Embodiment Construction

[0019] The method for detecting the closing core action and closing failure of a spring energy storage type circuit breaker is characterized in that it includes the following steps:

[0020] a) Detect the opening coil;

[0021] b) Detect the opening mechanism;

[0022] c) Detect the trip plate;

[0023] d) Detect the closing rod of the iron core;

[0024] e) Detect the limit screw of the circuit breaker.

[0025] further:

[0026] The method for detecting the closing core action and closing failure of the spring energy storage type circuit breaker is characterized in that: the step a) includes, if the opening coil is electrified or short-circuited, repairing it.

[0027] The spring energy storage type circuit breaker closing core action and closing failure detection method is characterized in that: the step b) includes, if the dead point self-locking function of the opening mechanism is unreliable or the opening mechanism after closing Action trip again, to be repaired. ...

Abstract

The invention discloses a spring energy storage type circuit breaker switch-on iron core action and switch-on fault detection method. The method is characterized by comprising the steps of (a), detecting a switch-off coil, (b) detecting a switch-off mechanism, (c) detecting a release plate, (d) detecting a switch-on iron core ejector rod and, (e) detecting a circuit breaker limiting screw. The detection method is provided based on the portion where a fault is possibly produced, the fault producing possibility and the overhaul complexity degree. According to the method, the fault portion can be rapidly detected and repaired in time, and normal running of a power gird is rapidly recovered.

Description

technical field [0001] The invention relates to a spring energy storage type circuit breaker closing core action and a closing failure detection method, which belongs to the technical field of circuit breaker maintenance. Background technique [0002] Due to its small size, good performance, no pollution, long life and many other advantages, spring energy storage circuit breakers are widely used in high voltage power grids, and basically completely replace various circuit breakers that are extinguished by other media. The ease of use and reliability of conventional vacuum circuit breakers have been greatly improved. In actual use, due to insufficient inspection and maintenance, circuit breakers often have certain problems, which affect the normal operation and safety of the power grid. [0003] The repair technology of circuit breaker parts has matured at present. Therefore, the key to the maintenance of circuit breakers is to quickly determine the fault location, restore i...
