Q: What is a recloser?

A: The reclosing device is a device that can automatically detect the fault current, and automatically cut off the circuit when the fault occurs, and then perform multiple reclosing operations.

Q: What is the function of the recloser?

A: It is mainly used in the distribution network. When there is a temporary fault in the line (such as a branch touching the line for a short time), the reclosing device restores power supply by reclosing operation, which greatly reduces the outage time and scope and improves power supply reliability.

Q: How does the recloser determine the type of failure?

A: It monitors characteristics such as the magnitude and duration of fault currents. If the fault is permanent, after a preset number of reclosing, the reclosing device will be locked to avoid further damage to the device.

Q: What are the application scenarios of reclosers?

A: It is widely used in the urban distribution network and rural power supply network, which can effectively cope with various possible line failures and ensure the stable supply of power.
