Along with the development in China electric power network market and the progress of high-voltage switch gear technology, the structure of vacuum circuit-breaker is by the original fixed middle disposed withdrawn type handcart that progressively develops into, progressively being regenerated by original oil-minimum breaker is vacuum circuit-breaker, and it is spring-operated, permanent magnet operating etc. that its circuit breaker operation mechanism is progressively regenerated by original Electromagnetically-operating.At present China's use spring operating mechanism mechanical transmission part is many, manufacturing process is complicated, take up room large, maintenance is inconvenient.Although permanent magnet type operating mechanism be acknowledged as middle pressure regeneration product, represented Medium voltage switch or circuit breaker development trend but at present the permanent magnetic actuator vacuum circuit breaker of different structure and principle also exist many problems.
Present permanent magnet type vacuum circuit-breaker, being summed up can minute monostable permanent magnet type vacuum circuit-breaker and two type of bistable permanent magnetic formula vacuum circuit-breaker, and they respectively have characteristics:
1, the operation principle of monostable permanent magnet type breaker closes a floodgate, also keeps by tripping spring the function of separating brake for relying on permanent magnetic to keep;
2, the operation principle of bistable permanent magnetic formula vacuum circuit-breaker is that separating brake relies on permanent magnetic to keep with the maintenance of closing a floodgate fully.
Put into operation till now from China's First Domestic permanent magnet type vacuum circuit-breaker, the permanent magnet type vacuum circuit-breaker applicable cases of comprehensive more various structures, can see it being that monostable or bistable permanent magnetic formula vacuum circuit-breaker all are to close a floodgate by electromagnetism, the electromagnetism separating brake, with spring separating brake etc., but all do not overcome the present situation that relies on permanent magnetic to keep fully, although permanent magnet type vacuum circuit-breaker, comparing spring-operated formula vacuum circuit-breaker optimizes many, but because designing technique is immature, such as along with the time, environment, the change of temperature and make that progressively going down of permanent magnetic cause minute, close a floodgate unreliable, certainly will bring huge economic loss to power industry, bring inconvenience for our the army and the people's life, so this root place that also to be permanent magnet type vacuum circuit-breaker do not widely popularize.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiency that existing spring-operated formula vacuum circuit-breaker and permanent magnet operating formula vacuum circuit-breaker technology exist, design a kind of safe and reliable and more practical middle disposed withdrawn type vacuum circuit breaker.
The technical scheme that its technical problem that solves the utility model adopts is: this middle disposed withdrawn type vacuum circuit breaker, the chassis vehicle that comprises main box, is installed in the magneto spring operating mechanism in the main box, three fixed sealing type bodies and installs in the main box lower end, the magneto spring operating mechanism comprises again the permanent magnet mechanism body, it is characterized in that: complementary switching-in spring assembly is set in the left side of permanent magnet mechanism body.
Described complementary switching-in spring assembly comprises that driving fairlead drives the outer auxiliary switching-in spring of fairlead with being sleeved on, and described driving fairlead upper end is fixed on the main box, and its lower end is rotationally connected by the first actuating arm plate and main shaft.
Described magneto spring operating mechanism comprise permanent magnet mechanism body, the first actuating arm plate, drive rod, first drive win in succession, the second actuating arm plate, second drives and wins in succession, activation lever and minute gate assembly, A, the B, the C three-phase transmission component that are fixed on the main box lower end are won in succession and the activation lever composition by actuating arm plate, driving, the upper end of each phase of A, B, C three-phase is rotationally connected by its actuating arm plate and main shaft respectively, and the lower end of its each phase is connected with insulator rotating by activation lever; Permanent magnet mechanism is installed on B phase right side at A, B, C three-phase, and described permanent magnet mechanism comprises permanent magnet mechanism body and the drive rod that moves up and down, and described permanent magnet mechanism is rotationally connected by the first the 3rd actuating arm plate and main shaft that drives in the connecting plate assembly; Gate assembly comprised tripping spring and fixed head in described minute, and the upper end of minute gate assembly is fixed on the main box, and its lower end is rotationally connected by tripping spring and activation lever; The pole body is rotationally connected by insulator and the activation lever that is connected to its lower end.
