Abstract
The invention relates to a shielding cover and a method for shielding point discharge at a bolt end by using the shielding cover, in particular to the shielding cover for shielding the point discharge at the bolt end, and belongs to the technical field of discharge shielding. The invention adopts the technical scheme that: the shielding cover comprises a hollow hemispherical cover body (1), a circular ring (2) and a hinge (3), wherein the hollow hemispherical cover body and the circular ring are connected through the hinge; the diameter of the hollow hemispherical cover body is greater than that of the circular ring and greater than that of a bolt and a nut to be shielded; and the bolt penetrates through parts to be fastened and then penetrates through the circular ring of the shielding cover, a spring gasket is arranged, the nut is screwed, and the hollow hemispherical cover body of the shielding cover is folded to cover the bolt and the nut. The invention has the advantages of easiness and convenience in operation and low cost, and by adoption of the shielding cover, a point at the bolt end is effectively shielded, the shape of an electrode is changed, an electric field is uniformly distributed, local discharge is avoided, and the quality of a product is guaranteed.
Description
Technical field
The present invention relates to a kind of radome and, particularly shield the radome of bolt end point discharge, belong to the discharge shroud technical field with its method that shields bolt end point discharge.
Background technology
In electric field, the shape of electrode is very important, if there is the wedge angle burr just to be easy to take place electric discharge phenomena, influences the quality of product.A lot of product needed are used the fastening parts of bolt; But electric discharge phenomena just possibly take place in the sharp corner of bolt end; Requiring to shield this discharging structure simultaneously can not be complicated, and cost can not be too high, and the discharge that how to shield generations such as wedge angle burr becomes this area problem demanding prompt solution.
Summary of the invention
The purpose of this invention is to provide a kind of radome and shield the method for bolt end point discharge with it; Effectively shielded the wedge angle of bolt end; Improve electrode shape, made Electric Field Distribution more even, prevented the generation of partial discharge; Guarantee the quality of product, solved the problems referred to above that background technology exists.
Technical scheme of the present invention is: a kind of radome, comprise hollow hemisphere shape cover body, circular rings and hinge, and be connected through the hinge between hollow hemisphere shape cover body, the circular rings, the diameter of hollow hemisphere shape cover body is greater than the diameter of circular rings.
The present invention is hollow hemisphere shape cover body, circular rings and a hinge of processing radome with stainless steel material.
A kind of method with the end point discharge of radome shielding bolt; Comprise following steps: 1. radome comprises hollow hemisphere shape cover body, circular rings and hinge; Be connected through the hinge between hollow hemisphere shape cover body, the circular rings; The diameter of hollow hemisphere shape cover body is greater than the diameter of circular rings, and greater than to shield the diameter of bolt, nut; 2. bolt passes the circular rings of passing radome behind the fastening parts of needs, fills up upper spring packing ring, fastening nut again, and the hollow hemisphere shape cover body with radome folds back at last, covers screw bolt and nut.
Good effect of the present invention: the present invention is simple and easy to do, and is with low cost, and radome has effectively shielded the wedge angle of bolt end, has improved electrode shape, makes Electric Field Distribution more even, has prevented the generation of partial discharge, has guaranteed the quality of product.
