Abstract
Provided is an insulation pull rod used for outdoor switch equipment. The outside of the insulation pull rod is wrapped by a sealing ring, the sealing ring is a corrugated sealing structure, the insulation pull rod is cylindrical and is provided with a boss, the boss is arranged at the upper part of the insulation pull rod, the lower side of the boss is provided with a silicone rubber sealing gasket, the silicone rubber sealing gasket and the insulation pull rod are integrally formed, the outside of the sealing ring is wrapped by a switch shell, and the switch shell is positioned at the inner side of a switch pole. According to the insulation pull rod used for the outdoor switch equipment, a fixing sealing structure is formed between the sealing ring, the switch shell and the switch pole, the insulation pull rod is assembled at the central position of a concentric circle of the switch pole, the insulation pull rod moves in a reciprocating manner along the axis of the concentric circle, the outside of the insulation pull rod is wrapped by the sealing member so that the sealing performance of an inner cavity of the switch pole can be enhanced, water vapor is prevented from entering the switch pole, the damage to electric power equipment is prevented, and the service lifetime of the switch pole is extended.
Description
Technical field
The utility model relates to a kind of switchgear parts, is specifically related to a kind of for the insulated tension pole on outdoor switch device.
Background technology
Along with the development of national industrial sector, the whole nation also constantly increases for the demand of electric power, the development of electric power impels the development of power equipment industry, the useful life of at present a lot of power equipments is shorter, in the process of power equipment operation, short circuit phenomenon constantly occurs, have a strong impact on the normal transmission of electric power, power equipment is usually arranged on open air, such working method makes power equipment often suffer the corrosion of rainwater, long-term rainwater corrosion can cause in power equipment has aqueous vapor to enter, the power equipment that enters aqueous vapor can cause power equipment running suddenly to stop, serious meeting causes the spontaneous combustion of power equipment, cause serious impact to people's life, industrial production can not ensure normal operation, cause serious economic loss.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, good insulation preformance a kind of for the insulated tension pole on outdoor switch device.
The technical solution of the utility model is: a kind of for the insulated tension pole on outdoor switch device, described insulated tension pole is wrapped with sealing ring, described sealing ring is ripple hermetically-sealed construction, described insulated tension pole is cylindric, described insulated tension pole is provided with boss, described boss is positioned at the top of insulated tension pole, described boss below is provided with silicone rubber seal gasket, described silicone rubber seal gasket is one-body molded with insulation railing, described sealing ring is wrapped with switch case, described switch case is positioned at the inner side of switch pole, described sealing ring, between switch case and switch pole, form fixing seal structure, described insulated tension pole is assemblied in the concentric circles center of switch pole, described insulated tension pole is along the reciprocating motion of concentric circles axis.
Described sealing ring is elastic insulating material sealing ring.
Described insulated tension pole and ripple hermetically-sealed construction adopt integrated formed structure.
The beneficial effects of the utility model are: be wrapped with seal at insulated tension pole; can improve the sealing property of switch pole inner chamber; prevent that steam from entering switch pole; cause the damage of power equipment, extended the useful life of switch pole, ripple hermetically-sealed construction can cut off switch pole and the exchange of extraneous gas; can not allow dust enter inside; ensure the normal operation of switch pole, thereby avoid the impact of environmental factor switching devices inside, play the effect of protection switch equipment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1 is insulated tension pole, and 2 is sealing ring, and 3 is boss, and 4 is silicone rubber seal gasket, and 5 is switch case, and 6 is switch pole.
