Product Description

Zw32-12f /630 high voltage vacuum circuit breaker 10kv watchdog outdoor post sw


ZW32-12 model outdoor vacuum circuit breaker(below abbreviated to be breaker) was outdoor distribution equipment with rated voltage of 12kV, 3-phase AC to 50Hz. It was mainly used at cut-off, close-down electric system load current, over load current and short current. It also can be used in substation and factories distribution power protect and control place, even in agriculture electric network frequent workplace. This breaker has compact , light weight, anti--condensation, maintenance-free virtue which can be used in harsh climate and dirty conditions.


Product Details


ZW32-12F high-voltage intelligent dividing vacuum circuit breaker (commonly known as watchdog) is used to switch off and close the load current, overload current and short-circuit current of rural power network, urban power network and small power system. The overall layout of the product is three-phase pole type. The three-phase vacuum interrupter is placed in the sealed pole. The insulation material is used to insulate between phases and the ground. The performance is reliable and the insulation strength is high. Recloser type intelligent circuit breaker. The basic and coincidence controller matches are applicable to the occasion of easy power supply, the PT and coincidence controller matches are applicable to the occasion of no power supply, the intelligent circuit breaker is applied to the radial power supply and loop network power supply system, the subsidy system eliminates the instantaneous impediment, actively regulates the power supply, also can cut off the eternal impediment, and realize the initiative of distribution network. Intelligent circuit breakers are equipped with 1-3 times of reclosure results, and the parameters of reclosure can be adjusted; Intelligent circuit breakers are equipped with the results of inrush current control, overcurrent shield and short-circuit quick-break combined shield, and the parameters can be continuously adjusted; Intelligent circuit breakers are equipped with small current grounding shield results, and the parameters can be continuously adjusted; The circuit can be controlled by wired remote control or by wireless remote control under the pole. Three-phase power system for switching 50Hz, voltage 10-12kV, used for interrupting and closing load current. It has overload and short-circuit shielding results, quick-break shielding results, time-delay shielding results, active reclosing results. It can also be equipped with lightning arrester or interrupting switch (i.e. combination of circuit breaker and interrupting switch) according to user's need. The intelligent circuit breaker has its own power supply, which can be operated by remote control in the vicinity, with CT and PT interfaces, and can satisfy the requirements of telemetry.The circuit breaker has arc extinguishing device, so the circuit breaker can be operated with load, not only to control the load current, but also to control the obstruction (short circuit) current; the circuit breaker has excellent packaging conditions. Potential, therefore, simply observing the circuit breaker, can not directly determine whether it is in the closed or open position.
