Utility model content
The purpose of this utility model is to provide the supporting construction of pole on the 110KV combined electrical apparatus of a kind of stabilized structure, good insulating.
The purpose of this utility model is achieved through the following technical solutions:
On 110KV combined electrical apparatus of the present utility model, the supporting construction of pole, comprises supports insulative platform, also comprises insulator, and the lower end of described insulator is fixed on the top cover of described supports insulative platform, and the upper end of described insulator is fixed on circuit breaker tank deck.
The technical scheme being provided by above-mentioned the utility model can be found out, the supporting construction of pole on the 110KV combined electrical apparatus that the utility model embodiment provides, owing to comprising insulator, the lower end of insulator is fixed on the top cover of supports insulative platform, the upper end of insulator is fixed on circuit breaker tank deck, can reinforce upper pole, improve the impact of arc spraying on insulation simultaneously.
Brief description of the drawings
The structural representation of the supporting construction of pole on the 110KV combined electrical apparatus that Fig. 1 provides for the utility model embodiment.
In figure: 1, supports insulative platform, 2, insulator, 3, radome, 4, circuit breaker tank deck.
Embodiment
To be described in further detail the utility model embodiment below.
The supporting construction of pole on 110KV combined electrical apparatus of the present utility model, its preferably embodiment be:
Comprise supports insulative platform, also comprise insulator, the lower end of described insulator is fixed on the top cover of described supports insulative platform, and the upper end of described insulator is fixed on circuit breaker tank deck.
The outer surface of described insulator is curved.
Between the top cover of described insulator and described supports insulative platform, be provided with radome.
Described radome is provided with multiple apertures.
The diameter of described aperture is 3mm.
The upper end of described insulator is that screw, lower end are double-screw bolt, and the screw of upper end is fixed by screws on described circuit breaker tank deck, and the double-screw bolt of lower end is fixed in the silk hole of top cover of described supports insulative platform.
The supporting construction of pole on 110KV combined electrical apparatus of the present utility model, on 110KV combined electrical apparatus, pole end installs insulator and radome additional, can reinforce upper pole, has improved the impact of arc spraying on insulation simultaneously.
Specific embodiment:
As shown in Figure 1, on 110KV combined electrical apparatus, on the top cover of the supports insulative platform of pole end, bore M24 silk hole, make the insulator of the poured with epoxy resin of diameter 120mm, consideration creepage, outer surface of insulator is arc circle, and the upper end of insulator is that screw, lower end are length 20mm double-screw bolt.Between insulator and the top cover of supports insulative platform, leave 2.0mm gap, the stainless steel shielding cover in U-shaped cross section is that 2.5 corrosion resistant plate spinning forms, simultaneously to be drilled with diameter be that the aperture of 3.0mm spreads all on surface, when installation, be placed on the top cover of supports insulative platform, the insulator with double-screw bolt can be fixed on upper pole.
The utility model adds an insulator at upper pole, and the lower end of insulator is fixed on the top cover of supports insulative platform, circuit breaker tank deck is fixed in upper end; The radome that adds a stainless steel between supports insulative platform and insulator, cover body spreads all over aperture, its role is to shielding the splashing of Arc In A Nozzle while cut-offfing everywhere, and gas also can overflow in aperture simultaneously.
The utility model on the basis of existing technology, by installing insulator fixed insulation platform additional, has been strengthened the mechanically stressed intensity of upper pole greatly, installs radome simultaneously additional and improves electric field, optimizes arc extinguishing condition.
The above; it is only preferably embodiment of the utility model; but protection range of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claims.
