Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] see Figure 1-3 , a vacuum high-voltage insulator, including an insulator body 1, the insulator body 1 is a segmented variable cross-section structure, which consists of a head, an upper cone with a small top and a large bottom, a cylinder, and a lower cone with a small top and a large bottom. Body and base, the taper angle of the upper cone and the lower cone is 45°, the external design of the insulator body 1 of the present invention adopts a segmented variable cross-section structure, and the surface of the insulator body 1 has no grooves, which ensures the overall ease of use. Machinability, and the 45-degree cone angle shape is used in the cone part, which improves the surface flashover voltage resistance.

[0026] A cavity is opened inside the insulator body 1, and the insert assembly 8 is accommodated in the cavity, an...

Abstract

The invention provides a vacuum high-voltage insulator comprising an insulator body having a segmented variable-section structure. A cavity is formed in inside the insulator body. An insertion assembly is accommodated into the cavity and consists of power terminals and two ground terminals; the power terminals and the ground terminals are inserted into an insulating support positioning block in asleeving manner; the end portions of the two ground terminals are in threaded connection to two sides of a ground terminal connection block and a columnar terminal is in threaded connection to the middle part of the ground terminal connection block; and the two ground terminals are connected with two contact rings by two connection conductors and the terminals and the contact rings form a completeloop. According to the vacuum high-voltage insulator, on the basis of optimization of the structural design, the appearance dimension is reduced, the raw material usage is reduced, and thus the costis lowered on the premise that the high workability, high connection reliability and good flashover-resistance level are ensured.

Description

technical field [0001] The invention relates to a vacuum high-voltage insulation device, in particular to a vacuum high-voltage insulator. Background technique [0002] The existing vacuum high-voltage insulation device adopts a relatively simple outline form in design, which has the problem of low surface flashover resistance voltage, and destructive surface flashover is prone to occur when working close to the rated high voltage upper limit, so that The functional failure of the product will bring great losses; at the same time, the existing internal connection structure design also has problems such as complex structure, difficult manufacture, and the stress in the forming process will easily lead to poor connection after forming, and the manufacturing cost is the highest. Not high enough. Contents of the invention [0003] Technical problem to be solved: the purpose of the present invention is to improve the flashover voltage level of the insulator surface from the de...
