Description
ZW43-12F outdoor high voltage intelligent vacuum circuit breaker is an outdoor high voltage switchgear with rated voltage of 12kV and three-phase AC 50Hz. Mainly used for disconnection
Close the load current, overload current and short-circuit current of the power system. It is suitable for protection and control of substations, industrial and mining enterprises and urban and rural distribution networks, especially for
Places with frequent operation and urban automatic distribution network. Comply with the following standards: gbat1984 high voltage AC circuit breaker and GB / t11022 high voltage open circuit breaker
Common technical requirements for standards of switching equipment and control equipment,
Features
The vacuum interrupter adopts patented solid sealing technology, small size, long service life, high reliability, and the shielding cover is exposed; epoxy resin encapsulation, good weather resistance, convenient transportation;
The operating mechanism adopts high-reliability bistable permanent magnet technology, simple structure, maintenance-free, and mechanical life up to 30,000 times;
Epoxy resin packaging: meets environmental protection requirements; widely verified outdoor performance; resistance to ozone and ultraviolet rays; strong, light, and not easy to break;
Permanent magnet mechanism: few moving parts; no maintenance required;
Vacuum arc extinguishing, solid insulation, small size, light weight, large breaking capacity, high insulation level;
Manual opening device: When the control system fails, manual opening can be used for emergency opening operation, and the rated load current can be disconnected reliably;
Position detector: The proximity switch is installed on the linkage shaft and does not require mechanical components. It can simply and reliably detect the opening and closing positions of the switch;
The switch shell is made of stainless steel or sprayed plastic, which has good corrosion resistance and weather resistance;
Separated to form a visible fracture, reliable interlocking to form a combined electrical appliance;
The controller realizes the functions of remote control, remote measurement, remote signaling, and remote adjustment.
