Deep Primary And Secondary Fusion Magnetic Control Column Mounted Circuit Breaker
ZW32-12/M630-25
This type of primary and secondary deep fusion vacuum circuit breaker is an outdoor power distribution equipment with a rated voltage of 12kV and three-phase AC 50Hz. It is mainly used for breaking and closing load current, overload current and short-circuit current in the power system. It is suitable for protection and control in substations and industrial and mining enterprises' power distribution systems, and is more suitable for rural power grids and places with frequent operations.
Simple structure: three-phase direct-acting structure, each phase monostable independent permanent magnet mechanism.
Fast and stable action: inherent opening time ≤10ms, closing time ≤30ms.
Ultra-low power consumption: capacitor energy storage power ≤20W, closing peak current ≤25A, opening peak current ≤3A.
Permanent magnetic material performance is stable and reliable: demagnetization temperature>175℃.
Reliable control: military-grade capacitors and circuit boards operate reliably and have excellent anti-electromagnetic interference performance.
Long life: The mechanism life is up to more than 30,000 times.
The circuit breaker has reliable breaking performance, no burning and explosion hazards, safety, maintenance-free, small size, light weight and long service life.
The circuit breaker adopts a fully sealed structure with good sealing, which helps to improve moisture-proof and anti-condensation performance, and is suitable for use in high temperature and humid areas. The circuit breaker is equipped with high-precision, wide-range voltage/current sampling sensors, and the incoming and outgoing lines can be equipped with phase voltage sensors to meet the requirements of fault detection, measurement, metering and line loss calculation.
The circuit breaker can be electrically closed and opened. It can be manually opened under the condition of power failure, and can also be remotely controlled (optional configuration).
The magnetic control mechanism is sealed inside the switch box, which can effectively prevent the switch from rusting due to long-term outdoor environment. The operating mechanism is novel, simple, reliable, small in size, and the mechanical life can reach more than 30,000 times.
An outdoor disconnector and circuit breaker can be installed to form an integrated whole, and the circuit breaker and disconnector have a reliable mechanical interlocking device.
