Abstract
The utility model relates to a design and manufacture field of an outdoor high-voltage AC porcelain knob type SF6 breaker, and discloses a static side device of outdoor high-voltage AC porcelain knob type SF6 breaker. The device comprises a flange, a support body, a static contact seat, a static contact and a silent arc contact, which is characterized in that the support body is cylandrical.
Description
Technical field
The utility model relates to outdoor high-voltage alternating current porcelain knob SF
6The design of circuit breaker and manufacturing field, particularly a kind of outdoor high-voltage alternating current porcelain knob SF
6The quiet side device of circuit breaker.
Background technology
Outdoor high-voltage alternating current porcelain knob SF6 circuit breaker belongs to three-phase mechanical linkage formula operating breaker, is made up of three one poles, can realize electric remote-control or manual on the spot.Along with the transformation energetically of urban and rural power grids, the application of this type of outdoor high-voltage alternating current porcelain knob SF6 circuit breaker is more and more widely.The supporter of the quiet side of this type of outdoor high-voltage alternating current porcelain knob SF6 circuit breaker adopts cylindric copper conductor, takes into account and supports and electric action, still, the internal end of travel of circuit breaker is bigger, and it is longer to need copper conductor, therefore, exist product centering bad on the one hand, cause and produce synchronism and spring increasing; Longer on the other hand copper conductor can not guarantee perpendicularity, causes bending in transportation easily.Above-mentioned two shortcomings cause copper conductor enlarged diameter, cost increasing, product from great.
Summary of the invention
The purpose of this utility model is to provide a kind of outdoor high-voltage alternating current porcelain knob SF
6The quiet side device of circuit breaker can overcome prior art and cause its enlarged diameter, cost increasing, product from great defective because of needing copper conductor than length, and can make circuit breaker obtain better thermal diffusivity, synchronism and spring property.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A kind of outdoor high-voltage alternating current porcelain knob SF
6The quiet side device of circuit breaker comprises the flange, supporter, stationary contact headstock, fixed contact and the quiet arc contact that are fixedly connected sequentially, it is characterized in that described supporter is a tubular.
Further improvement of the utility model is that described supporter is an aluminum barrel; Its further characteristics be that be fixed with sorbent tube on the described flange, described sorbent tube is positioned at described aluminum barrel, the SF that described aluminum barrel is inside and outside
6Gas is communicated with.
Because the utility model changes supporter into and is tubular, under the material of homogeneity with amount, tubular structure obviously is being better than column structure respectively aspect intensity, water conservancy diversion, the heat transfer; Especially adopt aluminum barrel, mechanical rigid and intensity are better than copper conductor, can overcome prior art and cause its enlarged diameter, cost increasing, product from great defective than length, and can make circuit breaker obtain better thermal diffusivity, synchronism and spring property because of needing copper conductor.
