The utility model discloses structural design is novel, will go up binding post, lower binding post, solid utmost point support connnection together through the fin for go up binding post, lower binding post and the solid radiating efficiency that seals between the utmost point post three and obtain the improvement, satisfied the market demand.

Description

A kind of vacuum circuit breaker with radiator structure

Technical field:

This utility model relates to vacuum circuit breaker, particularly relates to a kind of vacuum circuit breaker with radiator structure.

Background technology:

Vacuum circuit breaker in the market is when operating current leads to bigger, easily produce bigger caloric value, mainly upper connecting terminal and lower connecting terminal, certainly pole also can produce caloric value, and on market, also some vacuum circuit breaker has radiator structure, is typically all for upper connecting terminal or lower connecting terminal, the demand of working environment cannot be met, therefore, how to solve the heat dissipation problem of three, be current problem demanding prompt solution.

Utility model content:

In order to make up prior art problem, the purpose of this utility model is to provide a kind of vacuum circuit breaker with radiator structure, novel in structural design, efficiently solves the heat radiation between upper connecting terminal, lower connecting terminal and pole three.

The technical solution of the utility model is as follows:

Vacuum circuit breaker with radiator structure, including pole, pole includes the ceramic shell of vacuum interrupter and outside thereof, pole upper and lower side is connected to upper connecting terminal, lower connecting terminal, wherein the lower end, lateral wall of pole is also associated with operating mechanism case, it is characterized in that, multiple fin spaced apart it is provided with between described upper connecting terminal and lower connecting terminal opposite face, fin embeds ceramic shell and along radial direction radial, and fin upper and lower side contacts with upper connecting terminal lower surface, lower connecting terminal upper surface respectively.

The described vacuum circuit breaker with radiator structure, it is characterised in that described fin be Ceramic manufacturing into strips, fin outer wall is coated with silicone grease layer.

The described vacuum circuit breaker with radiator structure, it is characterised in that described lower connecting terminal embeds in insulating mounting post.

The utility model has the advantages that:

This utility model novel in structural design, is linked together upper connecting terminal, lower connecting terminal, pole by fin so that the radiating efficiency between upper connecting terminal, lower connecting terminal and pole three is improved, and meets the market demand.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the present utility model.
