Outdoor Auto Circuit Recloser is a kind of power equipment which combines circuit breaker and automatic reclosing function. When a line fault is detected, it automatically disconnects the circuit to isolate the fault area and attempts to re-close the circuit after a preset interval to restore power to the non-fault area. If the fault is rectified, the coincidence is successful. If the fault persists, it is disconnected again, and several attempts may be made until a preset number of overlaps is reached or a permanent fault is detected.

Zi Kai Outdoor Auto Circuit Recloser Feature And Application
Feature
Enhanced power supply stability: The built-in automatic reclosing mechanism automatically isolates the fault area and quickly restores the power supply to the non-fault area, effectively reducing the power outage duration and impact range.
Reduce operation and maintenance overhead: Its compact design simplifies the maintenance process and significantly reduces the labor and time costs required for regular inspection and repair.
Environmental protection and energy efficiency: The use of oil-free design significantly reduces the negative impact on the environment, fully in line with the pursuit of green and energy-saving contemporary power systems.
Wide adaptability: The device can be flexibly adapted to the power system requirements of different voltage levels and electrical characteristics, demonstrating excellent flexibility and wide application compatibility.
Application
Overhead distribution lines: On the overhead distribution lines of urban and rural power grids, automatic reclosers can quickly isolate and restore power supply to non-fault areas, reducing the scope and time of outages.
Substation: Automatic recloser can improve the stability and reliability of the power supply system on the incoming and outgoing lines of the substation.
Industrial and commercial power: For industrial and commercial users with high reliability requirements, outdoor automatic reclosers can significantly reduce the loss of power outages caused by line failures.
