Abstract

The invention relates to the technical field of power grid maintenance, and discloses a device for replacing a permanent-magnet circuit breaker controller in a charged mode. The device comprises a first plug, a second plug, a third plug, a fourth plug and a connecting guide rod, wherein the upper end of the first plug, the upper end of the second plug, the upper end of the third plug and the upper end of the fourth plug are respectively fixedly installed on the connecting guide rod and electrically connected with the connecting guide rod. The first plug, the second plug, the third plug and the fourth plug are respectively inserted into a first terminal, a second terminal, a third terminal and a fourth terminal to break the current circuit of the controller, then the controller is powered off, and the controller can be replaced, so that charged replacement of a permanent-magnet circuit breaker is realized, the phenomenon of power-off caused by damage of the permanent-magnet circuit breaker controller is prevented, the maintenance of lines is reduced, the line shutdown time is reduced, personal injury and equipment accidents caused by maintenance are avoided, and the use of insulating tension is not influenced.

Description

technical field [0001] The invention relates to the technical field of power grid maintenance devices, and relates to a device for replacing a permanent magnet circuit breaker controller with electricity. Background technique [0002] Power users have higher and higher requirements for power supply reliability. In recent years, power system upgrades and transformations have been accelerated. During the process of line automation transformation, permanent magnet circuit breaker controllers have failed and been damaged, resulting in failures due to replacement of control systems. Power outages occur from time to time, seriously affecting the normal operation of the power system. For the newly installed permanent magnet circuit breaker, after running for a period of time, the controller will be damaged and the black screen will appear, resulting in the failure of the permanent magnet circuit breaker to operate normally, resulting in the line leapfrog protection action and expan...
