Magnetic Pole Mounted Circuit Breaker
Magnetic pole mounted circuit breaker adopts three-phase arrangement structure, vacuum longitudinal magnetic field arc quenching, opening and breaking performance is stable and reliable; pole column adopts solid insulation structure, voltage sensor, current transformer and other charged bodies are directly embedded inside the insulated pole column, used for monitoring the three-phase current and zero-sequence current, as well as the three-phase voltage and zero-sequence voltage. The operating mechanism adopts a flexible magnetic operating mechanism, which is simple and reliable, and can effectively avoid the design defects of the traditional spring-operated mechanism, which is easy to stagnate and corrode, so that the reliability of the mechanism is greatly improved.
The switch is easy to install, long service life (mechanical life up to 30,000 times) and other excellent features.
Core Function
- Magnetic pole mounted circuit breaker is widely used in city network or agricultural network as sectional switch or contact switch, used in outdoor substation of agricultural network distribution system as outlet switch, for 10kV system as the protection of load current, overload current and short-circuit current, and can be used in conjunction with FTU/feeder terminals FTU as the automatic detection, isolation, alarm and monitoring of line operation in the segment and branch line faults of the loop network line, with the function of automatic restoration of power supply to non-faulty sections.
- The circuit breaker can meet the requirements of power distribution automation after being equipped with measurement, protection, control and communication modules.
Application Scenario
Magnetic pole mounted circuit breaker is mainly used in power distribution network to open and close the load current in the power system, close the overload, and short-circuit current. It is suitable for substations and industrial and mining enterprises to protect and control the power distribution system, and it is also suitable for urban power grids, rural power grids and places with frequent operation.
