Zw32M - 12 permanent magnet vacuum circuit breaker

Product introduction

ZW32M - 12 series of outdoor high voltage permanent magnet vacuum circuit breaker for a period of 12 kv, rated voltage of the three-phase ac 50 hz outdoor distribution equipment.Is mainly used to open and close of electric power system load current, overload current and short circuit current.Suitable for urban and rural power grid for protection and control, more suitable for frequent operation.

Circuit breaker adopts advanced reliable monostable permanent magnetic operating mechanism, the magnetic field generated by the rare earth permanent magnets to keep closing position, eliminating the traditional institutions delicate energy storage, lock, such as machinery, simplify the structure, the number of parts decreased by over 70% than traditional institutions, not only simplified the assembly, and greatly improves the reliability and life expectancy.Due to using the capacitance as an operating current at the same time, also avoid the auxiliary power supply fluctuation on the influence of agency action features.The excellent performance of the permanent magnet operating mechanism can be frequent operation for a long time, life can be as much as 100000 times, and truly permanent free maintenance.

Circuit breaker intelligent permanent magnet controller, not only for the permanent magnetic operating mechanism provides a stable working power supply, also provides a reliable circuit breaker protection function and control means, intelligent permanent magnet controller has the complete switching inrush current, over current, short circuit protection function, the protection parameters are adjustable;Intelligent permanent magnet controller also have operation and remote control function on the spot, at the same time use the RS232 communication interface, intelligent permanent magnet controller, by choosing different means of communication, the breaker can also realize the wired/wireless/fiber such as remote control, to achieve the "four remote" operation of power system.
