What is china automative isolator disconnect rotary battery?

        China Isolator Disconnect Rotary Switch is an important switching device in the electrical system of power plants and substations, and needs to be used in conjunction with high-voltage circuit breakers. The isolation switch is suitable for indoor equipment with three-phase AC 50Hz and additional voltage of 12KV. It is used for connecting high-voltage equipment under voltage and load, blocking or converting lines. Its main function is to ensure the safety of high-voltage electrical appliances and equipment during overhaul operations, and have the effect of blocking voltage. It cannot be used to block, input load current and break short-circuit current. It can only be used for certain switching operations without strong arcs. That is to say, it does not have arc extinguishing function; it is divided into indoor type and outdoor type according to the device address, and divided into single-pillar type, double-pillar type and three-pillar type according to the number of insulating pillars. There are optional equipment for each voltage level. .

The China Isolator Disconnect Rotary Switch ensures the safety of high-voltage electrical appliances and devices during maintenance operations, and has the effect of blocking voltage. It cannot be used to block, input load current and break short-circuit current. It can only be used for certain switching operations without strong arcs. It means that it does not have the arc extinguishing function; it is divided into indoor type and outdoor type according to the different device addresses. According to the number of insulated pillars, it is divided into single-pillar, double-pillar and three-pillar. There are optional equipment for each voltage level. It can also reliably block the parts that need to be powered off from the live parts in the high-voltage power distribution device to ensure the safety of maintenance operations. The contacts of the China Isolator Disconnect Rotary Switch are all exposed to the air and have a significant disconnection point. The isolating switch has no arc extinguishing device, so it cannot be used to block load current or short-circuit current, otherwise the disconnection point will occur under the effect of high voltage The violent arc is difficult to quell by itself, and may even cause arcing (relative or phase-to-phase short circuit), burn equipment, and endanger personal safety. This is a serious accident called "pull disconnecting switch with load".

　　 high-voltage isolation switch can also be used to switch some circuits to change the operating method of the system. For example: In a double-bus circuit, a China Isolator Disconnect Rotary Switch can be used to switch the circuit in operation from one bus to another.
