Abstract

The invention discloses a method and device for detecting the action time of a primary and secondary fused switchgear assembly. The method is executed by a controller, the controller directly sends atripping and closing command to an IGBT driving module to control a control mechanism of a circuit breaker to act, and action trigger is completed by manually triggering a first key; the controller further simulates a tripping and closing instruction of the primary and secondary fused switchgear assembly to communicate with a feeder automation terminal through a first communication module, tripping and closing actions are conducted through the feeder automation terminal and the control mechanism of the circuit breaker, and action trigger is completed by manually triggering a second key; the method is executed by the controller, if it is detected that the first key is pressed down, a first working mode is switched, and the action time of a circuit breaker body is detected; if it is detectedthat the second key is pressed down, a second working mode is switched, and remote control of circuit breaker action time detection is simulated; and after detection is completed, detection data arestored and displayed on a display module, convenience and reliability are achieved, and precision is high.

Description

technical field [0001] The invention relates to the technical field of power equipment detection in a distribution network, in particular to a method and a device for detecting the action time of a complete set of primary and secondary fusion switchgear. Background technique [0002] In recent years, with the rapid development of smart grid construction, higher requirements have been put forward for the intelligence of distribution network. As its key support, the integration of primary and secondary equipment of distribution network is the development of standardization and integration of distribution network equipment. trend. The primary and secondary fusion complete switchgear is the most important equipment in the power system. Its main function is to control the opening and closing of various power lines and load equipment during normal or fault conditions, so as to ensure the normal operation of the power system. The primary and secondary fusion switchgear is the main...
