Description
Technical field
The present invention relates to low-voltage circuit breaker technical field, be specifically related to one under short circuit current, dynamic and static contact can be scolded out the also breaker of the structure of contact terminal that can open fast of disjunction simultaneously simultaneously.
Background technology
Low-voltage circuit breaker can be used for the short circuit current protection of circuit. Concerning some current limiting type circuit breakers, before the physical fault short circuit current of circuit reaches circuit prospective short circuit current peak value, moving contact will be scolded out under the effect of electrodynamic repulsion force, produces electric arc, thus the further rising of limiting short-circuit current.
General breaker, when by short circuit current, only has moving contact to be scolded out, and produces electric arc, limiting short-circuit current, and due to opening apart from limited of moving contact, the rising of arc voltage also can be restricted.
Summary of the invention
In order to solve the deficiencies in the prior art, the one that provides of the present invention is under short circuit current, and dynamic and static contact can be scolded out the also breaker of the structure of contact terminal that can open fast of disjunction simultaneously simultaneously.
The technical solution that the present invention adopts is:
A kind of breaker of the structure of contact terminal that can open fast, comprise pedestal, static contact component, rotating moving contact component and operating mechanism, described pedestal is provided with stationary contact bracket, described static contact component is hinged in stationary contact bracket, described moving contact component is provided with moving contact rack, described moving contact component is hinged on moving contact rack, , between described static contact component and stationary contact bracket and moving contact component and moving contact rack, be also provided with elastic component, between described static contact component afterbody and moving contact component afterbody, be also provided with the linkage that makes move toward one another between them.
The breaker of the described a kind of structure of contact terminal that can open fast, described stationary contact bracket is provided with chute, described static contact component and the jointed shaft of stationary contact bracket are in chute, described linkage comprises connecting rod, described connecting rod one end is connected with static contact component bearing pin, the described connecting rod other end is hinged on moving contact rack, described moving contact component is connected with moving contact rack by bearing pin, described moving contact rack is hinged on pedestal, and described moving contact rack can rotate around jointed shaft.
The breaker of the described a kind of structure of contact terminal that can open fast, described elastic component bottom is supported respectively at stationary contact bracket and moving contact rack, and static contact component and moving contact component 3 are supported respectively in described elastic component top.
The breaker of the described a kind of structure of contact terminal that can open fast, described stationary contact bracket is provided with snap fit, and described elastic component is connected on snap fit.
The invention has the beneficial effects as follows: the breaker that the invention provides a kind of structure of contact terminal that can open fast, before short circuit current rises to expection maximum, not only moving contact can be scolded out by electrodynamic repulsion force, static contact also can synchronously be scolded out, produce electric arc, arc voltage is improved fast, effectively limit the rising of short circuit current, simultaneously after mechanical unlocking, be subject to the effect of connecting rod, static contact stays on and is scolding open position, ensure between contact compared with large opening, effectively reduce the logical energy of permitting of breaker, improved the short circuit breaking capacity of breaker.
