The Role Of High Voltage Isolating Switch

High Voltage Disconnect Switch is characterized by its obvious segmented gap and is mainly used to isolate high-voltage power supplies to ensure safe maintenance. It also has the ability to switch on and off certain small currents. However, it should be noted that the device is not equipped with a special arc extinguishing device, so it cannot cut off the normal composite power supply, let alone short-circuit current. In practical applications, disconnectors are often used together with high-voltage circuit breakers to maximize their effectiveness. In addition, high-voltage disconnectors can also be used to perform switching operations of certain circuits, thereby changing the operating mode of the power system. For example, in a double-bus circuit, it can smoothly switch the operating circuit from one bus to another bus.
