Abstract

The invention discloses a secondary circuit simulation device of a breaker. The secondary circuit simulation device of the breaker is used for solving the problem that the existing simulation breaker cannot really simulate the actual action of the breaker of an electrical system in the absence of spring energy storage function. The device comprises an on-site closing circuit, a spring energy storage circuit, a spring energy dis-storage circuit and a spring energy storage indicating circuit, wherein the spring energy storage circuit connected with the on-site closing circuit is triggered after conducting the on-site closing circuit; when a trip time of a time relay 1 SJ of the spring energy storage circuit is not reached, the spring energy dis-storage circuit connected with the on-site closing circuit is triggered; the spring energy dis-storage circuit controls a spring energy dis-storage indicting circuit connected with it. The secondary circuit simulation device of the breaker can really simulate the actual action condition of the breaker of the electrical system, and has the function of simulating the spring energy storage.

Description

technical field [0001] The invention relates to the field of substation protection automation, in particular to a circuit breaker secondary circuit simulation device. Background technique [0002] At present, the analog circuit breakers on the market adopt all-digital circuits, and the time is set by digital dial codes, which can realize the functions of analog circuit breaker tripping and closing time setting, three-phase / separate-phase operation selection, input signal logic control, etc., thereby simulating the operation of the circuit breaker. Jumping, closing action. Its principle is complex and expensive, and it cannot simulate SF6 low pressure alarm, lockout, spring energy storage alarm and other signals. The opening and closing indication of the circuit breaker is not intuitive. , cannot directly express the structure of the actual circuit breaker, nor can it truly simulate the actual action of the circuit breaker in the power system. Contents of the invention ...
