Emergency switching-on device for power grid 10KV distribution line permanent magnet intelligent circuit breaker

Abstract

The invention relates to the technical field of 10KV power distribution network lines, and particularly relates to an emergency closing device for a power grid 10KV distribution line permanent magnet intelligent circuit breaker. The invention aims to solve the technical problems that closing can not be performed because of a fault, maintenance is not convenient and production cost is high. In order to solve the technical problem, the invention provides the emergency closing device for the power grid 10KV distribution line permanent magnet intelligent circuit breaker. The device is mainly composed of a shell, a PLC, a partition plate, a sliding column mechanism, a switching mechanism and a base mechanism and is directly installed in a permanent magnet intelligent circuit breaker so that the problem that the permanent magnet intelligent circuit breaker cannot be closed manually after the fault occurs is solved. Closing power supply of a power grid power supply line can be recovered under the condition that an original controller cannot work due to a power loss, emergency closing operation can be performed on a circuit breaker under the condition that an internal power supply, communication, guidance, control and software and hardware systems of the original controller have independent faults or cascading faults or even have all faults, operation is simple, the structure is small, production cost is low, and carrying is convenient.

Description

technical field [0001] The invention relates to the technical field of 10KV power distribution network lines, in particular to an emergency closing device for a permanent magnet intelligent circuit breaker of a 10KV power distribution line in a power grid. Background technique [0002] The permanent magnet intelligent circuit breaker is a switchgear installed and used in large quantities on 10KV distribution lines in the construction of the State Grid in recent years. Compared with the traditional spring intelligent circuit breaker, the technology is more advanced, the action is more reliable, and the opening speed is faster when the line fails. ; It can more effectively, quickly and accurately remove line faults, and is more and more favored by the power system, but the existing emergency closing device of the permanent magnet intelligent circuit breaker of the 10KV power distribution line of the power grid has the following defects; [0003] In the actual use of the existi...
