Description
Technical field
The utility model belongs to instrument transformer technical field, is specifically related to a kind of outdoor voltage transformer.
Background technology
Outdoor voltage transformer is measuring voltage in electric power system, the equipment of electric energy or relaying protection, pushing forward comprehensively especially along with national distribution automation work, various intelligent outdoor pole top switch and demarcation switch adopt in a large number, outer through wind owing to being exposed to throughout the year, rain erosion, make the damage that the parts such as the binding post on current transformer and conductive clamp are subject in various degree, it is accurate that impact is measured, increase failure rate, there is certain potential safety hazard, the short circuit of current transformer generation internal structure is even there is time serious, explosion, device security and personal safety are threatened.
Common outdoor mutual inductor has in use procedure, because product uses out of doors, the design of cluster parachute requires very high.When cluster parachute is unreasonable, rainwater can be made to flow to ground along instrument transformer surface, and rainwater itself is conductive materials always, when there is moisture content on whole instrument transformer surface, the surperficial creep distance of product can be caused to reduce, easily cause product creepage, cause product surface to puncture.
Utility model content
The purpose of this utility model is to provide one and eliminates safe hidden trouble, and avoids rainwater to form following current along product surface, the outdoor voltage transformer that the surperficial creep distance of product can not reduce because of the reason of rainwater.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Outdoor voltage transformer, comprise voltage transformer device body, the insulation shell be arranged on outside voltage transformer device body, the insulation king-post be arranged on the upper surface of insulation shell, fuse is provided with in described insulation king-post, described insulation king-post comprises the first insulation king-post and the second insulation king-post, and described being built by epoxy resin between the first insulation king-post, the second insulation king-post and insulation shell is integrated; The outer wall of described insulation king-post is uniformly distributed and spaced full skirt, one end of described full skirt is connected with the outer wall of described insulation king-post, the other end of described full skirt is provided with the conduction part for guiding rainwater, described conduction part is bent to form barb-like downwards, real waterproof design has been accomplished in the cluster parachute design of this product, the cluster parachute of product is designed to reverse hook type, makes rainwater be unlikely to form following current along product surface, the surperficial creep distance of product can not be reduced because of the reason of rainwater.
Further, be provided with projection immediately below bottom described full skirt, described projection is between the outer wall and conduction part of described insulation king-post.Even if the design of projection make rainwater along full skirt lower surface to insulation king-post direction flow into time, projection also well can play the effect of stopper, thus improves rain proofness.
Further, the shape of described projection is water-drop-shaped.Above-mentioned being designed with is beneficial to rainwater and flows away along the direction of projection, makes rainwater be unlikely to form following current along product surface.
Further, the first described insulation king-post and second insulate and forms the angle of 30-35 degree between king-post.
The utility model, owing to have employed above technical scheme, has significant technique effect:
Real waterproof design has been accomplished in the cluster parachute design of the utility model product, the cluster parachute of product is designed to reverse hook type, make rainwater be unlikely to form following current along product surface, the surperficial creep distance of product can not be reduced because of the reason of rainwater, and practicality is improved.
