*The VI in 10-VPR-32D (1,250A).

● Exposure

of live parts in the main circuit has been minimized even in VCBs with a 3,150A rating. This enhances safety through prevention of potential hazards such as short circuits caused by intrusion of small animals.

Earthing switch

● The

mechanical parts are coated with a long-life grease that contributes to the prevention of oxidation degradation and oilless bearings has been adopted for the bearing section of latch, thus extending the lubrication cycle to mechanical parts from three to six years and reducing the time required for maintenance. ● Includes a new withdrawable with door closed* (in addition to the conventional lever-based insert/draw-out mechanism) with cam-slide mechanism that reduces operating effort, saves time and enhances VCB safety. *Mechanism used to insert/draw-out the circuit breaker from the external panel based on IEC 62271-200 switchgear standards.

●

Enhanced options including additional auxiliary switch and earthing switch. ● VCB with the rated normal current up to 3,150A is transported together with a panel by shipping clamps. ● Compatibility with mounting frame of previous 10-VPR-C Series (positions of mounting holes, terminals and partitions are the same).

Minimizing exposure to the live part of a main circuit

Withdrawable with door closed (Type-M)

● No

use of the six hazardous substances (mercury, cadmium, lead, hexavalent chromium, PBB and PBDE), a measure that exceeds the requirements of RoHS standards. One example is use of a rust-proofing treatment for small parts such as pins and screws that is free of hexavalent chromium, a substance known to contaminate soil. ● Marking of main resin materials to facilitate recycling.

Cutting-edge Technologies Using 3D CAD and CAE VCB Structure

to Ensure the Utmost Levels of Reliability and Safety Operating Mechanism

● Through

use of thermal fluid analysis, we have realized efficient of heat to the cylinder-shaped insulation frame covering the VCB main circuit part, enabling a self-cooling mechanism up to a rated current of 3,150A.

● Greater

performance reliability and extension of the lubrication cycle from three to six years through measures for the mechanism such as minimizing the number of parts, reducing the number of moving parts, adopting oilless bearings and use of a long-life grease.

● More

reliable distribution of operating friction (which, due to the addition of a spring load, is difficult to verify/evaluate) has been achieved thanks to utilization of a three-dimensional mechanical simulation used to switch operation from the operating mechanism to a VI contact.

● Compound

insulation of insulated parts and air has been optimized through analysis and testing, resulting in a basic impulse level (BIL) up to 95kV, yet at a size equivalent to the previous 10-VPR-C Series. ● Materials

with superior tracking resistance have been adopted a cylindrical shape realized through stress analysis of the insulation frame and cutting-edge molding technology.

M2, E2, and C2 Classes Described in the Specifications (IEC62271-100) Classification as for Mechanical Endurance ( M1 and M2 )

3 / 6 / 10 / 15-VPR-25D / 32D / 40D Series*3

The IEC standards broadly divide the mechanical operating test into classes M1 and M2. At the control voltages shown in Table 1, class M1 requires the rated operation sequence to be performed 2,000 times in total while class M2 requires the rated operation sequence to be performed 10,000 times in total. At five times the actuating cycle of class M1, class M2 represents a highly reliable operation class. Table 1 M1 and M2 operating sequence. Control voltage

Probability of Restrike during Capacitive Current Switching (C1 and C2) Performance in capacitive current swiching test is broadly divided into classes C1 and C2; class C2 is highly reliable. Class C1: Low probability of arc restrike at the time of capacitive current switching test (2 restrikes are allowed during O 24 operations and CO 24 operations). Class C2: Very low probability of arc restrike at the time of capacitive current switching test (Restrikes is not allowed during O 24 operations and CO 24 operations).

*1 Rated short-circuit breaking current of 40kA with E2 class cannot be manufactured. And basic impulse level (BIL) with rated voltage 12kV has BIL75kV and BIL95kV. *2 Fixed (type-L) with rated current of 2,500A or 3,000/3,500A cannot be manufactured. *3 Please refer to the JNEC-SI-0150 catalog for 3/6-VPR-25D type with a rating of 1,250A or lower for information regarding class E1, withdrawable (types C,D and G) and fixed type-L.

LSC1 : No partition LSC2A-PI : No partition in the cable room LSC2A-PM : No partition in the cable room LSC2B-PI : Partitions in all compartments LSC2B-PM : Partitions in all compartments

*Arc restrike is the phenomenon that occurs when current flows later than a 1/4 of a cycle after zero when there are insufficiencies in the VCB arc extinction or in insulation stress between VCB poles for recovery voltage.

◎ Precautions （１）Caution for circuits containing harmonics As is the case with general high-pressure capacitors, please exercise caution when applying CR suppressors to circuits with higher harmonic waves. Particular care is required regarding multiple-order harmonic waves which may have flowed into circuits used for current control via the thyristor. When using a CR suppressor, set the effective value of resultant current with harmonic waves to the values shown in the table below (values are 1.3 times the rated value). Table 11 Effective value of resultant current with harmonic waves. Type

（４）Caution for withstand voltage tests 1.Please conduct a withstand voltage test after removing any wire connections. 2.Take care to ensure that test voltages and application times are correct. Depending on transformer capacity, excessive current flow may prohibit the test from being performed. For withstand voltage tests where the panel includes a CR suppressor, the CR suppressor must be disconnected from main circuit.

Technical Information Operation Mechanism and Operating Principles

Operation / Control Voltage (Current) Table 17 Variation range of operation/control voltage.

Closing Operation Fig. 53 shows the state where the circuit breaker is opened and the closing spring is discharged.

Standard

Electrical (Closing) Operation ① When the power supply is connected, auxiliary relay 52Y is excited via limit switch LS2 and the contact of auxiliary relay 52Y closes, which then activates the motor via LS2, and the contact of auxiliary relay 52Y starts to charge the closing spring. When the closing spring is completely charged, limit switch LS2 opens, the motor then stops and limit switch LS1 closes (the closed control circuit is formed). ② By closing the closing command switch CS1 in this state, the closing coil CC is excited, the closing latch of the operating mechanism is released and the circuit breaker closes as a result of the energy from the charged closed spring. Through discharging the closed spring, LS2 is closed and LS1 is opened. ③ When limit switch LS2 closes, the motor activates and charges the closing spring to prepare for the next closing operation. ④ When the circuit breaker is closed, circuit breaker auxiliary contact 52b opens and shuts off excitation of closing coil CC. At the same time auxiliary contact 52a closes and forms a trip circuit of the voltage trip coil STC and at the same time excites the auxiliary relay (for anti-pumping prevention) 52X.

If consecutive closing commands are given to the closing operation switch CS1 while charging the closed spring (charge time of motor: 6 seconds): limit switch LS1 closes, the closing coil CC is excited, and the circuit breaker closes after completing the charging of the closing spring.

② When the circuit breaker is opened (tripped), circuit breaker auxiliary contact 52a opens and shuts off excitation of STC to prepare for the next closing operation.

Trip-free Operation If the closing command and trip command are given simultaneously when the circuit breaker is in an opened state and the closing spring is in a charged state (closing preparation):

③ When performing the closing operation, it is necessary to release the closing command by closing command switch CS1 and then restore auxiliary relay 52X.

10-VPR-D VCBs are designed and manufactured as an indoor unit and comply with JEC-2300 (AC circuit breakers) and IEC 62271-100. Accordingly, these VCBs require a normal service conditions specified in Table 24. Furthermore, sufficient maintenance and inspections must be performed in accordance with the VCB instruction manual. Please consult the manufacturer regarding operation of VCBs under special conditions.

Caution for Installation Site and Surrounding Environment The VCB service conditions must comply with the specifications shown in Table 24. Do not use the VCBs in environments that do not meet these conditions. For use in outdoor panels and special environments where there is excessive dust, corrosive gas, water/condensation or abnormal vibration/shock, be sure to take appropriate countermeasures. Non-adherence to these cautions may result in damage to the products or degraded performance in areas such as switching, current carrying capacity and insulation.

Application of Surge Protection Device

Load device

Table 26 Withstand voltage test voltage value of load device (11kV system).

VCB load devices are generally considered to include transformers, rotators and capacitors. When the surge voltage is higher that the insulation level of a load device, one of the surge protection devices shown in Table 25 must be applied. The withstand voltage of transformers, rotators and capacitors as listed in the IEC standards are shown in Table 26. Please confirm the overvoltage tolerance of each device with the relevant manufacturer.

Dry transformer

Oil transformer

General purpose arrester used

Not required

Mitsubishi Electric Phase-advanced molded transformer capacitor General-purpose arrester used

Not required

*1: To directly switch the semiconductor rectifier unit (for example, a electric power thyristor rectifier unit) to the secondary side of a transformer, use a transformer with a contact-protective plate. Use a general-purpose arrester on the primary side and the surge protective device (such as a filter capacitor) on the secondary side. *2: Avoid interrupting the no-load excitation inrush current of a molded transformer oil transformer. When such current must be interrupted, use a general-purpose arrester. Before using any oil transformer or molded transformer made by other manufacturers, consult the manufacturer. *3: For motors in applications where inching operation is frequently performed and inching is the predominant switching duty (cranes, conveyors, etc.), use a CR suppressor.

Application to different-system circuits Application to different-system circuits is possible. In this case, it is necessary to shorten the maintenance, inspection and cleaning cycle because the voltage added between VCB poles will be higher than under normal conditions. A more frequent maintenance and inspection cycle is especially important in environments where there is pollution or high humidity.

Caution for Korndorfer Start Circuit For a korndorfer start, a neutral point release of the auto-transformer should be conducted after the start current is completely diminished. Alternatively, for an auto-transformer that is used as a starting compensator, please use a korndorfer system startup transformer specified in "power transformer (JEC-2201)."

Application to Electric Furnace Circuit High frequency switching of the circuit breaker for an electric furnace increases the possibility of generating a switching surge, and when a filter capacitor is connected there is a risk of generating high overvoltage. In addition to adopting a surge protection device, please use a circuit breaker with a high withholding voltage or select a circuit breaker with a rated voltage in one of the top classes.

Surge Voltage for Breaking Current Surge voltage at the time of interrupting current generally includes the current chopping surge when interrupting an inductive small current. If small current is interrupted by a switch that is superior in arc extinction capacity like the vacuum circuit breaker, the arc suddenly dissipates before forcing the current to zero and then interrupts current. This is called the current chopping phenomenon, and a high surge voltage may be generated if the phenomenon occurs at the time of inductive small current breaking. It is possible to calculate the current chopping surge voltage by the following general equations.

Service Life and Applications Vacuum Service Life of VI The high vacuum of the VI in the VCB ensures interrupting and insulation characteristics. It is very important that this vacuum be maintained. Our VIs are manufactured on our advanced production line and provide safe, long term use guaranteed by our original method of service life testing and control. Vacuums can be inspected simply as part of regular inspections via the withstand voltage method or through use of portable vacuum checkers.

Electrical Service Life of VI (see Table 27) The electrical service life of a VI is determined by the electrode consumption and the number of switchings. For VPR-D, the service life can be determined by the number of load switchings, because the electrode consumption is extremely small. Therefore, it is not required to measure the electrode consumption (wipe) at the time of maintenance and inspection.

Replace When Service Life Expires The estimated service life is 20 years when used under normal environmental conditions. When the VCB reaches the end of its mechanical service life or its specified operation count, it is necessary to replace the VCB.

When using the VCB in altitudes over 1,000m above sea level, the insulation withstand level is reduced due to differences from the standard ambient conditions. To make corrections for altitude, please confirm and apply the insulation withstand levels for higher altitudes as listed in IEC 62271-1-2011.

For installations at an altitude 2,500 m, if VCB is required with BIL 75kV, VCB with BIL 95kV should be used in accordance with Figure 65. “75 multiplied by 1.2 is 90.”
