As a kind of priority scheme of the present utility model, between the outer wall of described guide rod and the inwall of sleeve body, exist gap to form air chamber, air chamber between guide rod and insulator, as supplementary insulation, can reduce capacitance of bushing, improves corona voltage and the sliding lightning of sleeve pipe and presses.
As the further optimization of above-mentioned preferred version, the inwall of described sleeve body is coated with semi-conducting glaze, and is provided with spring leaf on the outer wall of semi-conducting glaze and guide rod.When electric pressure is higher, corona will occur and above-mentioned effect was lost efficacy in the above-mentioned air chamber inside be arranged between guide rod outer wall and sleeve body inwall, at this moment adopt the air chamber short-circuit structure, be coated with semi-conducting glaze at the sleeve body inwall, and connect and make the air chamber short circuit with spring leaf and conductor, in order to eliminate inner corona, thereby make air chamber recover to improve the effect of corona voltage and sliding lightning pressure.
As another kind of preferred version of the present utility model, be provided with the insulation full skirt on the outer wall of described sleeve body.When the inwall coating semiconductor glaze in sleeve body, and be provided with spring leaf on the outer wall of semi-conducting glaze and guide rod, when eliminating inner corona, but corona and sliding the sudden strain of a muscle still may occur in sleeve pipe, by the insulation full skirt is set on the outer wall of sleeve body, improve the flash-over characteristic of sleeve pipe.
Further, the number of described insulation full skirt is at least two, and is symmetrical set on its outer wall along the center of sleeve body, thereby plays the effect of better raising sleeve pipe flash-over characteristic.
The number of described insulation full skirt is preferably two, but is not limited to two, also can be according to actual conditions select separately the to insulate number of full skirt.
The material of described sleeve body is preferably pottery or insulating resin, thereby plays the effect of insulation, but the material of sleeve body is not limited to pottery or insulating resin, also can select separately other insulating material according to actual conditions.
The material of described guide rod is steel material, but the material of guide rod is not limited to steel material, also can select separately other materials according to actual conditions.
Preferably, described end cap is installed on the inwall of sleeve body, thereby is convenient to the installation of end cap and the dismounting in when maintenance.
Be provided with seal between the inwall of described end cap and sleeve body, thereby can make the zone between the outer wall of the inwall of sleeve body and guide rod form a seal cavity, and then the effect that improves air chamber, significantly reduce capacitance of bushing, improve corona voltage and the sliding lightning of sleeve pipe and press.
The utility model compared with prior art, the advantage had and beneficial effect:
1, the utility model is by being arranged to insulating sleeve two parts of mutual sheathing, be positioned at outside sleeve body, and be arranged on the inner guide rod of sleeve body, when using, only cable need be passed from the inside of guide rod, can realize the insulation effect of cable, its mount scheme, and insulation effect is good.
2, gap is set between the outer wall of the utility model by the inwall by sleeve body and guide rod and forms air chamber, can reduce capacitance of bushing, improve corona voltage and the sliding lightning of sleeve pipe and press.
3, the utility model, by the insulation full skirt is set on the outer wall of sleeve body, improves the flash-over characteristic of sleeve pipe.
4, the utility model is by between the inwall in end cap and sleeve body, being provided with seal, thereby further improved the effect of air chamber.
