Description
Technical field
The utility model relates to actuating mechanism, more specifically says so to be used for the electromagnetic push driven machine of electric power system circuit breaker.
Background technology
Operating mechanism is referred to as the nerve center of circuit breaker, is one of importance of weighing vacuum circuit-breaker performance quality, and following several stages has approximately been experienced in its development: manual operation mechanism, electromagnetic mechanism, spring mechanism and permanent magnet mechanism.
Relying on the operating mechanism that manually directly closes a floodgate is manual operation mechanism, and it is mainly used to the very little circuit breaker of low, the specified drop-out current of actuating electric pressure, and its weak point is can not automatic reclosing, can only local operation, safety inadequately.
The operating mechanism that closes a floodgate by electromagnetic force is that the shortcoming of electromagnetic operating mechanism is that the power that consumes of closing coil is too big, needs to be equipped with that expensive storage battery, switching current are big, structure is relatively heavier, operate time is longer.
Spring operating mechanism utilizes the spring of energy storage to realize feed motion for power makes switch, and it can adopt manpower or small-power AC and DC motor to drive, and is a kind of operating mechanism the most frequently used in the circuit breaker.But general spring operating mechanism has more than 200 part, and transmission mechanism is comparatively complicated, and failure rate is higher, and moving component is many, the requirement on machining accuracy height, and manufacture process requirement is higher.And the power producing characteristics of spring mechanism and the load characteristic of vacuum circuit-breaker are not complementary, and carry out appropriate design on cam profile curve and bar linkage structure.In addition, the complex structure of spring operating mechanism, sliding friction surface is many, and how at key position, in the long-time running process, the wearing and tearing of these parts, corrosion and bleeding of lubricant, curing etc. all can cause operate miss.And then cause the generation of following situation:
1, circuit breaker tripping is promptly sent operation signal to circuit breaker and is not closed a floodgate or separating brake;
2, close not brake application or close after be disjunction;
3, relaying protection action during accident, circuit breaker can not divide;
4, burn out closing coil.
Permanent magnet mechanism is that electromagnetic mechanism and permanent magnet are combined, avoided the unfavorable factor that on/off switch position machinery is threaded off, fastener system caused, need not mechanical energy and by the confining force that permanent magnet produces circuit breaker is remained on to close, on the separating brake position.Be equipped with control system and realize the desired repertoire of circuit breaker.The advantage of this mechanism is relatively simple for structure, reduces about 60% with its parts of spring mechanism comparison; Failure rate also reduces thereupon, the reliability height, mechanism's life-span is long, volume is little, in light weight.But because of the moving separating brake motion that participates in unshakable in one's determination, the movement inertia of kinematic system obviously increases when making separating brake, and is very unfavorable to improving just-off speed aspect opening characteristic; Because of the need permanent magnet keeps, so be subjected to the restriction of manufacture craft and cost.
