Abstract
The utility model relates to a high-current solid sealed pole which forms natural convection heat dissipation by using variations in the specific gravity when the air is heated. The high-current solid sealed pole comprises an upper terminal and a lower terminal which are embedded in an internal cavity of a solid sealed pole insulating body, wherein one sides of the upper and lower terminals are exposed outside the insulating body, and the other sides are connected with two ends of a vacuum arc-extinguishing chamber in the solid sealed pole respectively in a direct or transitional manner; the lower terminal is provided with one or n convection heat dissipation holes, and the convection heat dissipation holes are communicated with the internal cavity of the solid sealed pole. According to the solid sealed pole adopting the technical solution provided by the utility model, when the internal temperature of the lower terminal and a moving conductive end cavity rises, the air inside the solid sealed pole forms natural convection heat dissipation because of variations in the specific gravity when heated, and the hot air flows out of the cavity through the convection holes so as to form air circulation convection, thereby reducing the temperature rise of a moving end of the solid sealed pole, and improving the overall operation condition of a switch.
Description
Technical field
The utility model relates to a kind of pole, relates generally to a kind of band from the great-current fixed sealed pole of heat radiation, is mainly used in protection and the control device of electric power system facility.
Background technology
Pole is that the conductive pieces that vacuum interrupter is relevant with circuit breaker is embedded into thermosetting simultaneously or thermoplastic class insulating material forms pole, makes whole circuit breaker polar constitute the parts of an integral body.Existing great-current fixed sealed pole generally comprises parts such as outlet seat, following outlet seat, vacuum interrupter, silastic cord breaker, Elastic Sliding fingertip, and through vacuum interrupter, the Elastic Sliding fingertip flows into outlet seat down to electric current from last outlet seat during use.Because the last outlet seat of this pole, following outlet seat, vacuum interrupter and Elastic Sliding fingertip are all coated wherein by solid insulating material, it is very outstanding that heat dissipation problem in the course of work seems, prior art generally is an aluminium radiator to be installed improve radiating effect above last outlet seat.But because the following outlet seat of pole and slip fingertip are in the bottom of pole, and insulated tension pole need be installed in the pole bottom, realize the branch resultant motion of vacuum interrupter, therefore can't install radiator additional in the bottom of pole, so local temperature rise is higher when causing pole work, force the user to take forced air cooling to realize cooling.
The utility model content
The purpose of this utility model provides the novel pole of a kind of novel structure, reasonable in design, good heat dissipation effect, need not additionally to increase air-cooled mechanism when utilizing this great-current fixed sealed pole, and whole temperature rise is low.
The technical scheme that realizes the utility model purpose is: a kind of great-current fixed sealed pole of being with from heat radiation comprises insulation shell and is arranged on the last terminals in the described insulation shell, following terminals, vacuum interrupter and Elastic Sliding fingertip; The upper end of described vacuum interrupter is the static conductive rod end, and described static conductive rod end is electrically connected with the described terminals of going up, and the lower end of described vacuum interrupter is the moving conductive rod end, and described moving conductive rod end is electrically connected with described terminals down by described Elastic Sliding fingertip; On the terminals some louvres are set under described, described louvre and described pole inner chamber connect.
Further, be filled with silastic cord breaker between described insulation shell and the described vacuum interrupter.
Further, described insulation shell is the solid insulating material housing.
The utlity model has positive effect: the pole that adopts the technical program, when terminals and elasticity fingertip temperature raise instantly, the heat of pole inside can pass through the outside heat loss through convection of louvre, thereby improved radiating condition greatly, improve the overall operation situation of switch, all processing and manufacturings of the utility model in addition, Installation and Debugging are fully the same with existing pole flow process, need not out novel die processed, have saved production cost in the time of practicality.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below.
Fig. 1 is structural representation of the present utility model.
Embodiment
See Fig. 1, the utlity model has material is the insulation shell 2 and the last terminals 1, time terminals 4, vacuum interrupter 6 and the Elastic Sliding fingertip 7 that are arranged in the insulation shell 2 of solid insulating material; Wherein the upper end of vacuum interrupter 6 is the static conductive rod end, this static conductive rod end is electrically connected with last terminals 1, the lower end of vacuum interrupter is the moving conductive rod end, this moving conductive rod end is electrically connected with following terminals 4 by Elastic Sliding fingertip 7, the described center of terminals 4 down is provided with louvre 5, described louvre 5 connects with the pole inner chamber, like this when pole inside cavity temperature raises, the air of pole inner chamber forms Natural Heat Convection because the proportion that is heated changes, hot-air flows outside cavity by louvre 5 and forms the air circulation convection current, thereby the temperature rise of the pole moved end that has reduced improves the overall operation situation of switch.In addition, present embodiment can also be on this technical scheme, by filled silicon rubber resilient coating 3 between insulation shell 2 and vacuum interrupter 6, avoids thermal stress to make the problem of pole housing cracking, has improved the whole service life of pole.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
