YIKA Indonesia Isolating Switch Disconnector Outdoor High Voltage Ceramic AC 24KV 400A Isolator Switch

   YIKA Indonesia Isolating Switch Disconnector Outdoor High Voltage Ceramic AC 24KV 400A Isolator Switch is an important switching device in the electrical system of power plants and substations. It needs to be used in conjunction with high-voltage circuit breakers. Its main function is to ensure the safety of high-voltage electrical appliances and devices during maintenance work, and act as an isolation voltage. It cannot be used for Cut off, input load current and break short-circuit current, it can only be used for certain switching operations that do not produce strong arc, that is, it does not have the arc extinguishing function; according to the installation location, it is divided into indoor type and outdoor type, according to the insulation pillar The number is divided into single-column type, double-column type and three-column type, with optional equipment for each voltage level.
Function:
1)   After opening, establish a reliable insulation gap, and separate the equipment or lines that         need to be overhauled from the power supply with an obvious disconnection point to ensure          the safety of inspection and maintenance personnel and equipment. 
2)    Change the line according to operational needs. 
3)    It can be used to divide and combine small currents in the circuit, such as the charging        current of bushings, busbars, connectors, short cables, the capacitance current of the switch voltage equalizing capacitor, the circulating current when the double busbar is switched, and the excitation current of the voltage transformer etc. 
4)    According to the specific conditions of different structure types, it can be used to divide and combine the no-load excitation current of a certain capacity transformer.
