What are the Functions of High Voltage Load Switches?

1.Purpose
High voltage load switch is a kind of electrical appliance whose function is between high voltage circuit breaker and high voltage isolating switch. Used to control power transformers. The high voltage load switch has a simple arc extinguishing device because it can turn on and off certain load current and over load current. But it can not break the short circuit current, so it is generally used in series with high voltage fuse, with the help of fuse to short circuit protection.

2.Features
Can isolate the power supply, has a clear disconnect point, used for fixed high voltage equipment. There is no arc extinguishing device, the normal operating current and short circuit can be passed in the closed state. It is strictly forbidden to connect or disconnect the circuit with load. It is usually used in series with high-voltage circuit breaker.

3.Function
Used for switching load current and switching short circuit current, switching load current, closed loop current, no-load transformer and cable charging current, switching short circuit current. Load switch equipped with grounding switch, can withstand short circuit current. The load switch-fuse combined appliance with tripping device and high breaking capacity fuse has the function of phase breaking and tripping, which can cut off short circuit current and be used as protection equipment.
