KYN28A- (12, 24) indoor metal
Indoor metal armored removable switchgear
KYN28A12 indoor metal armored medium-volume removable switchgear (hereinafter referred to as the switch) is a three-phase AC 50Hz indoor complete power distribution device for receiving and distributing 3-12 kV network power and implementing circuits Control protection and monitoring. Various types of microcomputer-based integrated relay protection devices can be installed on the panel of the relay cab of this product, and the system can be intelligently controlled. It has remote control, telemetry, remote signaling and remote adjustment functions, and is controlled by the CAN bus with a communication interface. Field network. And it has the functions of preventing the misoperation of the circuit breaker, preventing the push-pull handcart with load, preventing the earthing switch from being turned on and off, preventing the earthing switch from transmitting power at the grounding position, and preventing accidentally entering the electrified interval. This cabinet can be equipped with VS (ie ZN3) and ZN12V vacuum circuit breakers, and can also be equipped with imported VD4 vacuum circuit breakers and VC series vacuum contactors.
