Description
Technical field
The utility model is related to a kind of pole, particularly a kind of easy heat radiation, the open pole of easy mold release.
Background technology
Pole is by vacuum interrupter (Vacuum interruptor) and breaker (Circuit-breaker) phase
The conductive pieces of pass are embedded into epoxy resin or this kind of solid insulating material easily solidified of thermoplastic simultaneously forms pole
Post, makes whole circuit breaker polar turn into the part of an entirety.
Under normal circumstances, 40.5kV poles, up and down outlet centre-to-centre spacing there was only 328mm, maximum is also with regard to 400mm or so.
But for electric current 3000A above products, because operating current is big, caloric value is high, outlet must take into consideration radiating up and down, that is,
Increase heat dissipation wind channel；Because 40.5kV product voltages are higher, it is desirable to which creep age distance is in more than 810mm, the radiating of this kind of product
Air channel must take corresponding measure, to solve Insulation Problems.
The content of the invention
The purpose of this utility model is that there is provided the open pole of a kind of easy heat radiation, easy mold release.The utility model
With good heat dissipation effect, good insulation preformance, the characteristics of easy mold release.
The technical solution of the utility model：The open pole of a kind of easy heat radiation, easy mold release, includes vacuum extinction
Room, vacuum interrupter, which is externally provided with insulation shell, vacuum interrupter bottom insulation shell, is provided with full skirt；The top of the insulation shell
Portion is upwardly extended and exceeds the top of vacuum interrupter, and heat dissipation cavity 3 is surrounded beyond part, the top of heat dissipation cavity 3 be it is open, absolutely
The first longitudinal air channel is distributed with edge housing, the upper end in the first air channel is turned on the heat dissipation cavity, and the bottom of insulation shell is set
There are the middle cavity of connection full skirt and second air channel in the first air channel.
Foregoing easy heat radiation, the open pole of easy mold release, the inwall in first air channel are provided with spiral convex rib.
The beneficial effects of the utility model：
1st, the utility model in insulation shell by setting the middle cavity in conducting full skirt and the air channel of heat dissipation cavity so that
Cavity and heat dissipation cavity are connected where lower outlet, add the distance in air channel, enhance the effect of airflow stack effect, radiating effect
More protrude, meanwhile, heat dissipation cavity is open, and more preferably, faster, cold air is out of full skirt in the course of work for speed for radiating effect
Middle cavity rises, and enters heat radiation rack through the second air channel, the first air channel, and from the 3rd air channel discharge, air flow process under
And on the heat at vacuum interrupter bottom, middle part and top is taken away together, substantially increase radiating effect.
2nd, the utility model considerably increases the creep age distance in air channel by setting spiral convex rib in the first air channel,
It ensure that the insulating requirements of pole.
3rd, convex tendon of the present utility model is by using helical structure, during shaping and demoulding, can be by core by rotary core pulling
Take out, compared with the design to enter, the structure considerably increases the creep age distance in air channel in the case of size is less, protect
The insulating requirements of pole have been demonstrate,proved, and have easily been stripped, have been easy to manufacture.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model；
Accompanying drawing 2 is the partial schematic diagram in the second air channel；
Description of reference numerals：1- vacuum interrupters, 2- insulation shells, 3- heat dissipation cavities, the air channels of 4- first, 5- spiral convex ribs,
Cavity in the air channels of 6- second, 7- full skirts, 8-.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment of the present utility model：
Embodiment：A kind of open pole of easy heat radiation, easy mold release, as shown in accompanying drawing 1-2,1, include vacuum and go out
Arc chamber 1, vacuum interrupter 1 is externally provided with insulation shell 2, and the bottom of vacuum interrupter 1 is provided with full skirt 7；The top of the insulation shell 2
Upwardly extend and exceed the top of vacuum interrupter 1, heat dissipation cavity 3 is surrounded beyond part, the top of heat dissipation cavity 3 be it is open, absolutely
The first longitudinal air channel 4 is distributed with edge housing 2（First air channel 4 is set along the circumferentially distributed of insulation shell 2 according to radiating requirements
Put the quantity in the first air channel 4）, the upper end in the first air channel 4 turns on the heat dissipation cavity 3, and the bottom of insulation shell 2 is provided with Connectable umbrella
Second air channel 6 in the air channel 4 of middle cavity 8 and first of skirt 7.
The inwall in first air channel 4 is provided with spiral convex rib 5.
During making, the position of vacuum interrupter 1 in a mold is set, material shaping, the demoulding is then injected into.During work,
Cold air enters from the middle cavity 8 of full skirt 7, from bottom to top takes away the heat around lower outlet and vacuum interrupter 1, and from dissipate
Hot chamber 3 is discharged, and is radiated.
