High voltage load switch is a vital device in the power system
A high voltage load switch is a kind of switching equipment that can control and protect the high voltage power system. It consists of a contact system, an operating mechanism, and a protective device. When it is necessary to carry out load access or disconnection, the operating mechanism controls the splitting and closing action of the contact system to realize the control of the load. The protection device can monitor the state of the circuit and cut off the current immediately once the abnormal situation is found, in order to protect the safety of equipment and personnel.
High voltage load switch can realize fast and safe access and disconnection of loads without interrupting the whole power system, which improves the working efficiency.
When a short circuit occurs in the circuit, the high voltage load switch can quickly cut off the current to prevent the accident from expanding and protect the safety of equipment and personnel.
When the load exceeds the rated value, the high-voltage load switch can automatically disconnect the circuit to avoid equipment damage due to overload.
When a ground fault occurs in the circuit, the high-voltage load switch can cut off the power supply in time to prevent electric shock accidents.
The high voltage load switch can be operated by a remote control signal, which improves the flexibility and convenience of work.
