Abstract
The utility model provides a high heat dispersion static contact of heavy current switch cabinet, including the static contact of one set of tube-shape, characterized by: the static contact is provided with a plurality of annular radiating fins on a half-section excircle with a cylinder bottom, and a radial hole is formed in the cylinder wall of the static contact upwards at a position close to the cylinder bottom. The utility model discloses a be equipped with the radial hole that is used as the radiating air duct and increase heat radiating area's annular fin, improved the cooling radiating efficiency of static contact, it has the silver layer to further improve its heat transfer efficiency to cover at the surface of static contact moreover.
Description
Technical field
The utility model relates to a kind of high heat dispersion fixed contact of high-current switch.
Background technology
Along with the high speed development of China's industry, need for electricity amount increases swift and violent, and the power consumption distribution of China is very unbalanced, the area of several industrialization prosperity, quantity as Yangtze River Delta Area, Pearl River Delta and Beijing-tianjin-hebei Region population and enterprise is much more compared with other places, and this proposes very large challenge to local supply of electric power.Especially in the summer of sweltering heat, residential electricity consumption and commercial power are all in peak period, high-current switch works long hours under high-load condition, the heat causing switch cubicle to produce significantly increases, significantly more than national sector standard, even there is the too high and tragedy of blast and " baked wheaten cake is operated " of switch cubicle Yin Wendu in temperature rise.All can bring huge economic loss and power grid maintenance cost every year.
The reason that switch cubicle produces heat significantly to be increased has a lot, but mainly because the fixed contact of switch cubicle is positioned at inside fixed contact box and forms enclosure space, and the fixed contact of prior art itself not make in heat radiation to set out rational structure meter yet, exacerbate the gathering of heat in fixed contact, thus the heat convection dead band temperature causing enclosure space to be formed is too high, and then lead to work safety accident.
Utility model content
Technical problem to be solved in the utility model, just be to provide a kind of high heat dispersion fixed contact of high-current switch, the heat dispersion of fixed contact self can be improved, effectively prevent the accident of power supply caused because fixed contact heating is too high, reduce maintenance cost, promote the safety and reliability of power supply.
Solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of high heat dispersion fixed contact of high-current switch, comprise the fixed contact of a sleeve-shaped, it is characterized in that: described fixed contact is being provided with several annular fin with on section cylindrical of half at the bottom of cylinder, the barrel of described fixed contact has a radial hole upward in position at the bottom of cylinder.
By having the annular fin design of radial hole and the increasing heat radiation area that can be used as heat dissipation wind channel, the cooling efficiency of fixed contact can be improved.
The surface coverage of described fixed contact has silver layer, can improve the heat transfer efficiency of fixed contact so further, thus improve its rate of heat dispation.
Compared with prior art, the utility model instrument has the following advantages:
The utility model, by being provided with the annular fin of radial hole as heat dissipation wind channel and increasing heat radiation area, improve the cooling efficiency of fixed contact, and has silver layer to improve its heat transfer efficiency further in the surface coverage of fixed contact.
Accompanying drawing explanation
Fig. 1 is cutaway view of the present utility model.
In figure: 1-annular fin, 2-radial hole.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of high heat dispersion fixed contact of high-current switch, comprise the fixed contact of a sleeve-shaped, it is characterized in that: described fixed contact is being provided with several annular fin with on section cylindrical of half at the bottom of cylinder, the cylindrical shell of described fixed contact has a radial hole upward in position at the bottom of cylinder.
By having the annular fin design of radial hole and the increasing heat radiation area that can be used as heat dissipation wind channel, the cooling efficiency of fixed contact can be improved.
The surface coverage of described fixed contact has silver layer, can improve the heat transfer efficiency of fixed contact so further, thus improve its rate of heat dispation.
Claims (2)
1. the high heat dispersion fixed contact of a high-current switch, comprise the fixed contact of a sleeve-shaped, it is characterized in that: described fixed contact is being provided with several annular fin with on section cylindrical of half at the bottom of cylinder, the barrel of described fixed contact has a radial hole upward in position at the bottom of cylinder.
2. the high heat dispersion fixed contact of high-current switch according to claim 1, is characterized in that: the surface coverage of described fixed contact has silver layer.
