Abstract
The utility model relates to an improve circuit breaker cabinet handcart contact, this circuit breaker cabinet handcart contact include moving contact and static contact, and the moving contact adopts the flat contact of GC type extension spring formula, and the static contact adopts the thick silver -plated copper preparation of 10mm. The clearance reduces between the sound contact, has increased the contact force between the sound contact, and it generates heat to have solved thoroughly burns out the trouble problem, has improved service reliability.
Description
Technical field
The utility model belongs to electrical equipment technical field, and particularly one improves breaker cabinet handcart contact.
Background technology
Breaker cabinet is widely used in electric power system, and breaker cabinet directly affects power supply reliability, will cause directly and indirect economic loss as broken down.In practice, the moving contact of breaker cabinet handcart contact adopts the flat contact of Extension Spring-type, and fixed contact adopts the thick sheffield plate of 8mm to make, when in certain hour after new equipment puts into operation, due to extension spring good springiness, dynamic/static contact contact is good, there will not be fever phenomenon, along with the growth of running time, due to metal fatigue, extension spring elasticity weakens, moving contact sensing finger pressure weakens, cause dynamic/static contact loose contact, occur the catastrophe failure of even burning of generating heat, cause unnecessary loss.
Utility model content
The purpose of this utility model is the heating burnout fault that solution type breaker cabinet handcart contact is in operation, a kind of improved circuit breaker cabinet handcart contact is provided, by increasing fixed contact thickness, gap between dynamic/static contact is reduced, add the contact between dynamic/static contact, solve heating burnout failure problems up hill and dale, improve power supply reliability.
For solving above technical problem, the technical scheme that the utility model adopts is:
A kind of improved circuit breaker cabinet handcart contact, comprise moving contact and fixed contact, moving contact adopts the flat contact of Extension Spring-type, and fixed contact adopts and thickeies sheffield plate making.
Preferably, moving contact adopts the flat contact of GC type Extension Spring-type.
Preferably, fixed contact adopts the thick sheffield plate of 10mm to make.
The beneficial effects of the utility model are as follows:
The utility model is thickeied to 10mm by the sheffield plate adopted by fixed contact, gap between dynamic/static contact is reduced, adds the contact between dynamic/static contact, solve heating burnout failure problems up hill and dale, improve power supply reliability.
Accompanying drawing explanation
Fig. 1: breaker cabinet handcart structure of contact terminal figure.
The flat structure of contact terminal figure of Fig. 2: GC type Extension Spring-type.
Fig. 3: the utility model transformation static contact structure figure.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1, Figure 2 and Figure 3, the utility model is by improving the physical dimension of JYN1-40.5 type breaker cabinet handcart fixed contact, and make fixed contact 1 with the thick sheffield plate of 10mm, change former fixed contact, moving contact 2 adopts the flat contact of GC type Extension Spring-type.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, other amendments that those skilled in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
