Abstract
The utility model relates to a matching assembly of power equipment and specifically relates to a large-current contact box having a radiating channel and used for a handcart switch cabinet. The large-current contact box having the radiating channel includes a box. The front end of the box is closed while the rear end of the box is provided with a mounting base. The box is provided with a bus bar outlet. The middle of the box is provided with a gap. The outer periphery of the gap is covered with a section of shade having a U-shaped section. The rear end of the shade connects with the outer wall of the box. The front end of the shade is a U-shaped opening. The radiating channel is formed between the shade and the box. By adopting the above structure, too much heat generated in the contact box can be discharged out of the box through the radiating channel formed between the shade and the box. In this way, the temperature in the box is lowered, and the temperatures of a static contact and a bus bar are lowered. The shade has a function of increasing a creeping distance in the gap, thereby guaranteeing the insulation safety of the large-current contact box having the radiating channel.
Description
Technical field
The utility model relates to the matching used parts of a kind of power equipment, specifically a kind of contact box that is used for the big electric current band louvre passage of handcart switch cabinet.
Background technology
The big electric current 4000A contact box of tradition, removing the busbar exit surface is hermetically-sealed construction entirely, when handcart normally moves in the service position; Compact because of the contact box space, radiating effect is not good, and contact box inside is easy to generate temperature and crosses problems such as height; Therefore often need to install 2 and force heat radiation with fan, this spline structure setting not only increases cost, and if blower fan damage; Can cause temperature rise too high, accidents caused, the environment for use of big electric current is caused a hidden trouble.
Summary of the invention
The technical problem that the utility model will solve provides a kind of contact box that effectively dispels the heat, improves the big electric current band louvre passage of security performance.
In order to solve the problems of the technologies described above, the contact box of the big electric current band louvre passage of the utility model comprises box body, the sealing of box body front end, and the box body rear end is provided with and installs and fixes seat; Box body is provided with the busbar outlet, and the box body middle part has a breach, the cover body that it is U-shaped that the periphery of breach is covered with one section cross section, and the cover body rear end is connected with the box body outer wall, and the cover body front end is the U-shaped opening, forms heat dissipation channel between cover body and the box body.
Said breach is arranged on the offside of contact box in the busbar outlet.
Said cover body and box body global formation.
After adopting above-mentioned structure,, the inner excessive temperature that produces of contact box is shed outside the box body fast, reduce the temperature in the box body like this, the temperature of fixed contact in the contact box and busbar is reduced through the heat dissipation channel that forms between cover body and the box body; The effect of cover body has increased the creepage distance of indentation, there, has guaranteed the insulation safety property of contact box.
Description of drawings
Fig. 1 is the front view of the contact box of the big electric current band of the utility model louvre passage;
Fig. 2 is the left view of the contact box of the big electric current band of the utility model louvre passage.
Embodiment
Below in conjunction with accompanying drawing and embodiment the contact box of the big electric current band louvre passage of the utility model is done further explain.
As shown in the figure; The contact box of the big electric current band louvre passage of the utility model; Comprise box body 1; Box body 1 front end sealing, box body 1 rear end are provided with and install and fix seat 8, can the contact box of the big electric current band louvre passage of the utility model be installed on the cabinet through the bolt that installs and fixes on the seat 8.Fixed contact 2 is installed in box body inner chamber front end, and fixed contact is connected with busbar 4, and box body 1 is provided with busbar outlet 9, and busbar 4 stretches out outside the box body 1 through the busbar outlet, and box body 1 middle part has a breach 6, and breach 6 is arranged on the offside of contact box in busbar outlet 9; The cover body 7 that it is U-shaped that the periphery of breach 6 is covered with one section cross section, the cover body rear end is connected with the box body outer wall, and the cover body front end is the U-shaped opening, forms heat dissipation channel 5 between cover body and the box body; Cover body 7 and box body global formation.
