VBL series lateral vacuum circuit breaker, as a competitive new type, is designed and developed by us. Its three-phase main conductive circuits are arranged vertically. It has small overall width, compact structure, suitable for box-type substations, ring main units and fixed type switchgears.
It has complete type specifications, the rated voltage is 24kv, the rated current is up to 4000a and the rated short circuit breaking current is up to 40KA.
Mechanism
1. Energy storage spring is integrated with the operation mechanism, precision, reliability and convenience of spring assembly are greatly improved.
2. Close and open are integrated, compact design, optimized kinematic mechanics performance, extended mechanical life, reduced size and easy to have intelligent extension.
3. gear drive, stable drive ratio, low noise, high mechanical strength, no chain break risk.
4. built-in charging handle, greatly increasing convenience of field operation and debugging.
5. Close and open trips are modular designed, one-step installation, only one screw is enough.
