Abstract
An assembled internal bevel bus bushing solves the problems of restricted adaptability and too demanding manufacturing accuracy of buses, which are caused by the reason that a high-voltage terminal and an insulator of an internal bevel bus bushing in the prior art are pressed into an integrated structure. The assembled internal bevel bus bushing is characterized in that a groove at the joint of the insulator and the high-voltage terminal adopts a circular arc-shaped opening to form a circular arc groove; the upper round platform of the insulator and the cone-shaped surface of the insulator adopt arc transition to form a circular arc lug boss; a high-tension shielding part is processed by aluminum alloy; two ring-shaped grooves are formed at the lower part of the contact surface between the high-voltage terminal and the high-tension shielding part, a conductive O-ring rubber seal is mounted between the two grooves, and a ring-shaped circular arc groove for an elastic baffle ring to be mounted therein is formed at the upper part of the two grooves; and the assembled high-voltage terminal can be displaced by 3 to 5 mm in the axial direction. The utility model has the advantages of reliable insulation, uniform electric field, reasonable structure, and reliable sealing; and various structural modes can be realized when the high-voltage terminals connected with the insulator have identical corresponding connection size, so that flexible use and strong adaptability are realized.
Description
Technical field
The utility model belongs to high voltage electrical apparatus technical field, and particularly a kind of HV Terminal is fabricated, be used between two equipment of Cubicle Gas-Insulated Switchgear or two inflation unit between a kind of assembled inner cone bus casing of connecting of bus.
Background technology
The inner cone bus casing is the main transition insulation component that the Cubicle Gas-Insulated Switchgear upper conductor entered and drew switchgear, and its insulation property and workmanship directly influence performance and the operational reliability and the personal safety of Cubicle Gas-Insulated Switchgear.Present inner cone bus casing that uses or title inner cone insulator, all be that HV Terminal and insulator are suppressed into integrative-structure, this HV Terminal and insulator are suppressed into the structure of one, the version that can not adapt to HV Terminal changes, and adaptability is restricted; Too high to the requirement of the bus accuracy of manufacture when connecting bus, manufacturability is also bad.
Summary of the invention
Problem to be solved in the utility model is, overcomes the deficiencies in the prior art part, and it is fabricated inner cone bus casing that a kind of HV Terminal is provided, and changes to adapt to the different version of HV Terminal.
The technical solution adopted in the utility model comprises HV Terminal, insulator, high voltage shield, the low pressure shielding part, embedded nut and seal groove, the groove at described insulator and HV Terminal junction surface is the circular arc mouth, form an arc groove, arc transition is adopted on the last round platform of insulator and the cone of insulator surface, form a circular arc boss, the outer surface of insulator is the protrusion arc conical surface, the inner chamber upper end is the face of cylinder, the lower end is a taper seat, described high voltage shield is processed by aluminium alloy, the contact-making surface bottom of HV Terminal and high voltage shield is provided with the bipassage ring connected in star, the conductive seal cushion rubber is installed therebetween, and top is provided with the annular arc groove of one installation elasticity baffle ring.
Described low pressure shielding part is formed by the stainless steel cloth compacting, and is welded together with embedded nut, realizes electric connection.
HV Terminal after the assembling is at the displacement that axially can form 3～5 millimeters.
Compared with prior art, the beneficial effects of the utility model are:
(1) insulation is reliable, electric field is even.The circular arc boss of insulator high-pressure side and the design of arc groove make the inside and outside electric field of product more even; The internal taper hole design can form good interface pressure with silica gel bus cover, uses phenomenons such as corona, discharge, flashover can not occur in Cubicle Gas-Insulated Switchgear.
(2) rational in infrastructure, sealing is reliable.When HV Terminal is installed by two conductive seal rubber sealings, better effects if, and realized that simultaneously HV Terminal connects with the electric of high voltage shield.
(3) adaptability is strong.HV Terminal, conductive seal cushion rubber and elasticity baffle ring assemble by designing requirement, and assembling back HV Terminal improves the manufacturability of bus manufacturing at the displacement that axially can form 3～5 millimeters.Simultaneously, HV Terminal with the measure-alike condition of insulator associated couplings under, can be designed to multiple version, occupation mode is more flexible, adaptability is stronger.
