Technical field
The present invention relates to high-voltage circuitbreaker field, in particular to a kind of ac high-voltage SF6 breaker and its operating machine of the spring
Structure.
Background technique
High-voltage circuitbreaker (or high-voltage switch gear) it can not only cut off or the no-load current in closed high voltage circuit and negative
Charged current, and overload electric current and short circuit current are cut off by the effect of relay protection when system jam,
It has quite perfect arc extinguishing structure and enough cutout abilities, can be divided into: oil-break (bulk oil circuit, few oil-break
Device), sulfur hexafluoride breaker (SF6 breaker), compressed-air circuit breaker, vacuum circuit breaker etc..
In the use process of breaker, the size of switching on and off speed directly influences breaker disjunction and closes short circuit
The ability of electric current is the reliable condition for guaranteeing breaker safe operation.The speed of switching on and off needs to be maintained at a reasonable model
In enclosing, when switching on and off speed is excessively high, it can cause to bounce excessive, the collision between dynamic and static contact repeatedly can exacerbate the mill of contact
Damage；Switching on and off speed is too low, then cannot quick disengagement failure electric current, cause the accidents such as overstepping or explosion.
Go out various types of high-voltage circuitbreakers currently on the market, and these high-voltage circuitbreakers, it is all to pass through bullet
The flexible of spring realizes the switching on and off of breaker, it is desirable to promoted to the speed of switching on and off extremely difficult.Because existing
Breaker its close a floodgate when, be that energy storage is carried out by the compression or stretching of spring, released in separating brake by the energy storage on spring
It discharges into, therefore the collision of contact can be than more serious when opening velocity is too fast.Since switching on and off is an opposite process
In, when accelerating closing speed, spring energy-storage will reduce, and opposite separating brake also will be slack-off, will cause conversely, separating brake becomes faster
It closes a floodgate slack-off.
Summary of the invention
The purpose of the present invention one is to provide a kind of spring operating mechanism, has the advantages that switching on and off is fireballing.
