Embodiment 1

[0043] like figure 1 As shown, the live indicator lead wire structure of the closed switchgear includes the gas box 3, the insulating sleeve 1 and the indicator lead terminal 6, the gas box wall of the gas box 3 includes the sleeve fixing wall 31, and the insulating sleeve 1 is fixed on the sleeve on the fixed wall 31.

[0044] The insulating bushing 1 includes a bushing main body, and an induction ring 2 is arranged inside the bushing main body, such as figure 2 As shown, the outlet terminal 5 is provided on the outer peripheral surface of the bushing main body, and the shape and structure of the outlet terminal 5 are as follows image 3 As shown, the outgoing terminal 5 is conductively connected with the induction ring 2 . An indicator lead terminal 6 is connected to the outlet terminal 5, and the outlet terminal 5 and the indicator lead terminal 6 are plug-in terminals, which are used for fitting and conduction in the form of plug-in, and the plug-in form is as follows: ...

Embodiment 2

[0049] Embodiment 2 of the live indicator lead wire structure of the closed switchgear provided by the present invention;

[0050] The difference between this embodiment and embodiment 1 is that, as Figure 4 As shown, in Embodiment 1, the lead terminal crimping piece 7 is used to press the indicator lead terminal 6 connected to the insulating bushing of each phase. In this embodiment, there are three lead terminal crimping pieces 7, Each lead terminal crimping piece 7 corresponds to a phase insulating sleeve respectively.

Embodiment 3

[0052] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the lead terminal crimping member 7 includes a support plate 73 with an L-shaped structure, and the support plate 73 with an L-shaped structure includes a support plate part and a connecting plate part. In the example, the lead terminal crimping member 7 is not provided with an L-shaped support plate 73 , and the indicator lead terminal 6 is crimped only by the crimping plate part 72 .

Abstract

The invention relates to a potential indicator lead structure of an enclosed switchgear. The potential indicator lead structure of the enclosed switchgear comprises a gas tank, an insulating sleeve and an indicator lead terminal, wherein the insulating sleeve is fixed on the gas tank wall of the gas tank. The insulating sleeve comprises a sleeve main body. An induction ring is arranged in the sleeve main body; an outgoing line terminal is arranged on the outer peripheral surface of the sleeve main body; and the outgoing line terminal is conductively connected with the induction ring. The indicator lead terminal is connected with a potential indicator lead and is used for being connected to the outgoing line terminal; and a lead terminal crimping part is fixed on the gas tank and is arranged on the indicator lead terminal to enable the indicator lead terminal and the outgoing line terminal to be kept in a connected state. The lead terminal crimping part is pressed on the indicator leadterminal, so that the indicator lead terminal and the outgoing line terminal can be kept in a connected state, and the problem that the line of the potential indicator is easy to wind can be solved.

Description

technical field [0001] The invention relates to a live indicator lead wire structure of a closed switchgear. Background technique [0002] C-GIS metal-enclosed switchgear has the characteristics of small size, compact size, maintenance-free, high reliability, good sealing and insulation performance, and is not affected by external environmental factors in the medium-voltage field. Therefore, it is used in power system distribution and high-speed railway distribution station construction. have been widely applied. The primary circuit of C-GIS metal-enclosed switchgear often realizes the communication between the inside and outside of the gas box through the insulating bushing. ensure. [0003] The main body of the existing insulating sleeve is provided with an induction ring, and an outgoing terminal is electrically connected to the induction ring; the insulating sleeve assembly also includes an indicator lead terminal adapted to the outgoing terminal, and the indicator lea...
