Vacuum Circuit Breaker(VCB)12KV 24KV 36KV BKV3(VS1)vacuum circuit breaker

Product Description

BKV3(VS1)-24KV vacuum circuit breaker

The BKV3-24 indoor H.V. vacuum circuit breaker is a three-phase indoor switchgear with a rated voltage of 24 kV. It provides control and protection for power plants, substations, electrical facilities, and industrial and mining enterprises. Its integrated design uses a VET operating mechanism and can be used as a fixed installation unit or as a mobile unit with a special advance mechanism. The handcart unit is composition uses some of the main circuit and can utilize the entire solid seal post with great reliability and requires no maintenance. To achieve smaller circuit breakers, it can be equipped with KYN28A 24 and other handcart switch cabinets. It can also be utilized in the house with fixed XGN switchgear.

VS1-Series circuit breaker features high stability and high reliability

Vacuum circuit breakers of the VS1-Series are engineered with unique transmission part optimization. The benefits of modular spring mechanisms include easy maintenance, quick power-off maintenance, high component diversity, and superior compatibility with vacuum interrupters, which significantly raises the technical specifications and yields even higher performance.

Applicable standards

1EC62271-100 High-voltage switchgear and control-gear-Part 100: Alternating-current circuit-breakers

Secondary circuit

The secondary control circuit boards of vacuum circuit breakers of the VS1-Series are modularly designed. High-grade self-fastener plugs are used for the mechanisms' electric connection, which makes replacement easier and guarantees a dependable electrical connection. * Superior functioning oil buffer

High-performance oil buffer

A high-performance breaking buffer can prevent mechanical endurance loss from partial overstress of vacuum interrupter bellows caused by moving contact overshoot by significantly reducing the overshoot and rebounding amplitudes of the moving contact of a vacuum circuit breaker during breaking. No re-ignition or restrike is detected during the switching capacitor bank test as the moving contact's rebounding amplitudes decrease.
