ZW□YF2-12 Outdoor Vacuum Prepayment and anti-power-theft Device is used to make and break load current, overload current and short-circuit current in the power system with rated voltage 12kV or below, three-phase AC 50/60Hz . The product is composed of a ZW8-12 type vacuum circuit breaker and a prepayment electricity selling management terminal controller. Equipped with the high precision CT and PT in the vacuum switch three-phase, SADC and box, it can realize three-phase current and voltage accurate metering through the combination with the controller. The control system and the switch body are closely linked and both indispensable. When the linkage between the switch body and controller is separated, the switch will automatically open and lock, and manual closing will fail (if GPRS and CDMA wireless backstage functions are selected). It will automatically feedback such information to management terminal to alarm. The device has anti electricity theft function, three-section protection function, metering function, prepayment function, auxiliary function, fault record and query function, remote communication fuction, ring network operation function and nearest remote control function.
