Abstract
The utility model relates to a frame-type breaker, comprising a casing, a tripping system, an electric transmission mechanism, a handle assembly and a contact terminal system, wherein the contact terminal system comprises a bus, flexible connections and a contact terminal, multipath parallel flexible connections are arranged on the bus, and the other end of each flexible connection is connected with the contact terminal. Because the multipath parallel flexible connections are arranged on the bus of the contact terminal system, current carrying area of the breaker is substantially increased, electric repulsive force is effectively reduced, and electric stability is improved.
Description
Technical field
The utility model relates to a kind of frame-type circuit breaker.
Background technology
As everyone knows; circuit breaker in the market in use; especially when work; because the current-carrying area of contact system is big inadequately, relative makes that the electrodynamic repulsion force during divide-shut brake is bigger, thereby influenced the electronic stability of circuit breaker greatly; and; limited current-carrying area also makes effective protection range of circuit breaker greatly reduce, and is very fast at present economic development, and the area that current/voltage is had relatively high expectations seems outdated.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, provides little, the electronic stability of a kind of electrodynamic repulsion force higher frame-type circuit breaker.
For achieving the above object, the utility model adopts a kind of frame-type circuit breaker, comprise housing, take off port system, electric transmissio mechanism, Handleset and contact system, described contact system comprises bus, is flexible coupling and contact, have being flexible coupling of multi-channel parallel on the wherein said bus, be preferably being flexible coupling of five parallel connections, and connect contact at each other end that is flexible coupling.
By above-mentioned improvement to prior art, be flexible coupling owing on the bus of contact system, be parallel with multichannel, make the current-carrying area of circuit breaker greatly increase, effectively reduced electrodynamic repulsion force, improved electronic stability.
Description of drawings
Fig. 1 is the front view of contact system among the utility model embodiment.
Fig. 2 is that A among Fig. 1 is to view.
Embodiment
Specific embodiment of the utility model is a kind of frame-type circuit breaker, comprise housing, take off port system, electric transmissio mechanism, Handleset and contact system, with reference to figure 1 and Fig. 2 as can be known, described contact system comprises bus 1, be flexible coupling 2 and contact 3, what have five tunnel parallel connections on the wherein said bus 1 is flexible coupling 2, and connects contact 3 at each other end of 2 of being flexible coupling.
Obviously, more than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.Claim and equivalent thereof that the claimed scope of the utility model is appended define.
Claims (2)
