POLE-MOUNTED CIRCUIT BREAKER
Outdoor high-voltage vacuum circuit breaker is used for AC 50Hz-12kV three-phase power systems, to switch load current, overload current, and short-circuit current. It is suitable for protection and control in substation and industrial distribution systems, and is ideal for urban and rural grid construction, upgrading, and frequent switching. When combined with an isolating switch, it can also be used as a sectionalizing switch.
Pole-Mounted Circuit Breaker Series
General
- The three-phase insulation pillar adopts outdoor epoxy resin solid or silicone rubber insulation, which has the advantages of high and low temperature resistance, ultraviolet resistance, aging resistance and so on. Using miniaturized spring mechanism, low energy consumption, mechanism transmission output adopts spindle sliding mode, no torque loss, dividing and closing transmission parts, high reliability; The current transformer is installed on the outgoing line of the moving end.
- The circuit breaker can be equipped with a disconnecting switch, three-phase linkage, with obvious visible fracture in the disconnecting switch opening state, and has an anti-mis-interlock between the circuit breaker body, convenient maintenance and safety.
- The high voltage vacuum circuit breaker equipped with vacuum arc quench chamber has the characteristics of stable and reliable opening performance, no combustion and explosion risk, safety, maintenance-free, small size, light weight and long service life. The circuit breaker adopts fully closed structure, good sealing performance and moisture-proof. Anti-condensation performance, suitable for use in high temperature and humid areas.
- The closing and opening of the circuit breaker can be operated manually or electrically and remotely. It can be matched with the controller to realize power distribution automation, and can also be matched with the coincidence controller to form a coincidence device. The operation mechanism is novel, simple, reliable, small size, and the mechanical life can reach 10,000 times.
