Abstract
The utility model relates to a flexible connection protecting component for a contact system of a universal circuit breaker, which is characterized by comprising a pure copper sleeve pipe which is sleeved on a flexible connection line of a movable contact of the universal circuit breaker. Because the square sleeve pipe is sleeved on the flexible connection line, the action of the electric field force to the flexible connection line is reduced. Therefore, the deformation of the flexible connection line is reduced, the overall curve of the flexible connection line is avoided when the universal circuit breaker is under the action of the larger current, the generation of the electric field force in the opposite direction is decreased, and further the breakage of the flexible connection line under the action of the large current is prevented.
Description
Technical field
The utility model belongs to a kind of omnipotent breaker, particularly relates to a kind of omnipotent breaker contact system guard member that is flexible coupling.
Background technology
Present known omnipotent breaker contact system is made up of moving contact and fixed contact, the process of its contact is: fixed contact is fixed, moving contact is connected with operating mechanism, and the branch action is closed in the control that is subjected to mechanism, therefore the current carrying part of moving contact is by hard connection with can movable being flexible coupling form, be flexible coupling and in the current-carrying process, work as the big especially and meeting fracture that requires to be flexible coupling under the non-shut-brake situation of electric current, thereby cause switch to lose the current-carrying effect.
Summary of the invention
The utility model provides a kind of and can solve the omnipotent breaker contact system weak omnipotent breaker contact system guard member that is flexible coupling that is flexible coupling for solving the technical problem that exists in the known technology.
The utility model for the technical scheme that solves the technical problem that exists in the known technology and take is: what it included a fine copper is used to be enclosed within be flexible coupling sleeve pipe on the line of moving contact of breaker.
The utility model can also adopt following technical scheme:
It is described that to be enclosed within the sleeve pipe that moving contact of breaker is flexible coupling on the line be square casing.
Advantage and the good effect that the utlity model has are: owing to adopted the technical scheme that puts square casing on moving contact of breaker is flexible coupling line, control has reduced the effect of electric field force to the line that is flexible coupling.Because reduced the be flexible coupling deflection of line of moving contact of breaker, thereby prevented omnipotent breaker moving contact of breaker under big function of current line integrally bending that is flexible coupling, reduce to produce reciprocal electric field force, fracture under the big function of current has further also prevented to be flexible coupling.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is used for the view that moving contact of breaker is flexible coupling with the utility model.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, the omnipotent breaker contact system guard member that is flexible coupling is a square casing 1 with fine copper plate bending process.
As shown in Figure 2, ten of moving contact 3 strands of lines 2 that are flexible coupling are divided into five groups in the omnipotent breaker contact system, all are with a square casing 1 at every group on being flexible coupling line 2.
Claims (2)
1. omnipotent breaker contact system guard member that is flexible coupling is characterized in that: what it included a fine copper is used to be enclosed within be flexible coupling sleeve pipe on the line of moving contact of breaker.
2. the omnipotent breaker contact system according to claim 1 guard member that is flexible coupling is characterized in that: described to be enclosed within the sleeve pipe that moving contact of breaker is flexible coupling on the line be square casing.
