Embodiment Construction

[0021] Referring to the accompanying drawings in the description, the following detailed description will be given for the shielding device for the live wire end of the secondary component of the power transformation equipment of the present invention.

[0022] Such as figure 1 , figure 2 As shown, the shielding device for the live wire end of the secondary component of the substation equipment of the present invention has a structure including a shielding device main body 1 and a pressurizing device. The inside of the shielding device main body 1 is provided with a jack 2 for inserting and releasing wires. The socket 2 is a blind hole, and several protrusions 8 are evenly arranged on the inner wall of the socket 2, which increases the friction of the wire 6 inserted into the socket 2 and prevents the wire 6 from slipping. The upper part of the jammer body 1 is provided with a pressurizing device; on one side of the jammer body 1 is provided with a coding dialer 4 and a test...

Abstract

The invention discloses a live wire end shielding device of a power transformation device secondary element. The problem that the wire ends are difficult to bundle and distinguish due to the fact that secondary element wiring is complicated and lead wires are tightly arranged is mainly solved. The live wire end shielding device structurally comprises shielding device bodies and pressurization devices, wherein plug holes for lead wires to be plugged are formed in the shielding device bodies, and the upper portions of the shielding device bodies are provided with the pressurization devices. One side of each shielding device body is provided with an encoding dialer and a test hole, and the test holes are communicated with the plug holes in the shielding device. The lead wire ends for secondary element wiring can be respectively plugged into the shielding device bodies different in color, maintainers can conveniently and quickly shield and test electrified lead wires, very easily distinguish positions needing wiring restoration and achieve the purpose of correct, safe and quick operation.

Description

technical field [0001] The invention relates to a shielding device, in particular to a shielding device for live wire ends of secondary components of power transformation equipment. Background technique [0002] With the promotion and application of intelligent substations, there are a large number of secondary components (such as relays, indicator lights, buttons, etc.) and operating handles in the substation equipment. Due to the long-term energization of these devices and the uneven quality of the devices themselves, in the maintenance of substation equipment, it usually involves live replacement of secondary components and operating handles or partial change of wiring methods while live. Usually, we need to use insulating tape to wrap the ends of the secondary live wires during live operation, so as to safely replace the components or change the wiring method. This is what we generally do now. Contents of the invention [0003] The purpose of the present invention is...
