ZW32-12 /M It is rated voltage of 12kV for the high voltage permanent magnet vacuum circuit breaker (hereinafter referred to as the circuit breaker).Three-phase ac 50Hz outdoor high voltage switching equipment. The circuit breaker is widely used in urban power grid as a break or contact switch, or in rural power distribution system outdoor substation output switch, it can effectively complete the work of the traditional coincidence unit. Full load current circuit breaker is a kind of intelligent switch with comprehensive protection developed by our company. It adopts vacuum arc extinguishing principle, permanent magnet operating mechanism, integrated microprocessing technology, modern network communication technology and new switch manufacturing materials. This product is mainly composed of vacuum circuit breaker permanent magnetic actuator and controller of ontology and the outer of PT three by air outlet and outdoor sealed cable for electrical connection, with functions of fault detection, protection and control function and communication function, it can detect switch reliable judgment, inlet and outlet side of the mA (mA) and zero sequence current and short circuit fault current, and realize automatic removal of single-phase grounding fault and short-circuit fault. The circuit breaker conforms to GB 1984-2003. DL/T 402-2007 and IEC60056.


ZW32-12 /M Outdoor Permanent magnet AC high voltage vacuum circuit breaker

★ Simple structure: adopt a new design of permanent magnet operating mechanism, further reduce the number of mechanical parts.

★ High reliability: the controller integrated with the "anti-jump" function, can effectively identify the fault current and closing inrush current, accurate protection.

★ Long life: the use of permanent magnet mechanism to make the mechanical characteristics of the circuit breaker more reliable, so that the integrated mechanical life of the whole machine including the arcing chamber than the original model increased several times, the life of up to 30,000 times.

★ Advanced control technology: standard configuration has (30m) wireless remote control operation function, and has manual operation function at the same time, the controller has a standard communication interface, through the expansion of wireless data communication module, can be convenient networking, to achieve "four telecontrol", to achieve the transport data exchange.

★ Powerful functions: Through expansion, it can easily form a coincidence unit and a sectionalizer, which can be used to distinguish permanent fault from temporary fault. At the same time, the control function of the permanent magnet mechanism controller can be used to realize various functions of networking, protection and operation according to the requirements of customers.

★ Small operation power: using the performance of permanent magnet mechanism, with a long life of the battery, directly from the CT energy, and can directly upgrade the circuit breaker into a coincidence unit, sectionalizer, can greatly improve the power supply quality of the grid. At that time, only the system's average load rate of more than 20% for 6 hours a day will be needed to balance the power of the controller and the battery. Users only need to connect the circuit breaker to the power grid system, without the need to set up the control power supply, and can work normally for a long time.
