Summary
The ZW43M-12 intelligent prepaid outdoor high voltage vacuum circuit breaker is an outdoor high-voltage switchgear with rated voltage of 12kV and three-phase ac 50Hz.It is mainly used to break the load current, overload current and short circuit current of the power system.It is suitable for the protection and control of substation, industrial and mining enterprises and urban and rural distribution network, especially suitable for the operation of frequent site and city network automatic distribution network.Meet the following standards: GB/T1984 "high voltage ac circuit breaker", GB/T11022 "common technical requirements for high voltage switch equipment and control equipment", DI402 "ac high voltage circuit breaker ordering technology condition >...
Model and its meaning
Product features
The vacuum arc extinguishing chamber adopts the patented solid sealing technology, small volume, long life, high reliability and shielding mask.Encapsulated in epoxy resin, good weather resistance, easy to transport:
The operating mechanism adopts the high reliability bistable permanent magnet technology with simple structure, no maintenance, and the mechanical life can reach up to 30,000 times.
Epoxy resin packaging: meet environmental requirements;Widely verified outdoor performance;Ozone and ultraviolet radiation;Strong, light, not fragile:
Permanent magnet mechanism: less moving parts;Need not maintain;Applying bistable permanent magnetic technique;
Adopt vacuum arc extinguishing, solid insulation, small volume, light weight, large capacity, high insulation level;
Manual brake device: when the control system fails, it can be used for emergency breaking operation, and the rated load current is reliable.
Position detector: the proximity switch is installed on the linkage shaft, without mechanical components, simple and reliable detection switch of the split position;
The switch enclosure is treated with stainless steel or spray, with good corrosion resistance and good weather resistance.
Can be combined with the isolation switch to form a visible broken and reliable interlock to form a composite electrical appliance;
It can be equipped with the controller to realize remote control, telemetry, remote letter, remote control "four remote" function.
