Digital substation transformer high-voltage porcelain bush wiring chuck

Abstract

The invention discloses a digital substation transformer high-voltage porcelain bush wiring chuck and belongs to the power engineering power distribution construction field. The digital r substation transformer high-voltage porcelain bush wiring chuck comprises a substation transformer high-voltage porcelain bush; the substation transformer high-voltage porcelain bush is provided with an electric conduction rod; the electric conduction rod is provided with an inner lock sleeve; a first opening is formed in the side wall of the inner lock sleeve; the inner lock sleeve is provided with an outer lock sleeve; a second opening is formed in the side wall of the outer lock sleeve; the bottom of the side wall of the outer lock sleeve is provided with a lead pressing plate; the outer lock sleeve is provided with a pressing sleeve; the top of the pressing sleeve is provided with a gasket; and a nut is arranged on the gasket. According to the digital substation transformer high-voltage porcelain bush wiring chuck of the invention, a tapered opening locking mode which is different from a traditional clamp is adopted; the size of the chuck is decreased; material consumption is decreased; the utilization rate of electric conduction materials can be improved; a high-temperature self-healing effect can be realized; and the color of thermochromic paint can change with the change of temperature, and a special temperature measuring device is not required to perform detection, and therefore, inspection work can be simplified.

Description

technical field [0001] The invention relates to the field of power distribution construction in electric power engineering, in particular to a high-voltage variable-voltage porcelain bushing connection chuck used in a digital substation. Background technique [0002] At present, there are mainly two types of high-voltage porcelain bushing clamps used in digital substations, one is ordinary clamps, and the other is bergamot clamps. There are mainly the following problems in use: [0003] 1) Ordinary wire clips and bergamot type wire clips require a lot of consumables, and the utilization rate of conductive materials is low. [0004] 2) During the long-term use of the wiring clip, the contact surface is prone to oxidation and corrosion, resulting in poor contact. At high temperature, the wiring clip expands, and the wire clip is separated from the conductive rod, which cannot be self-healed. [0005] 3) When inspecting the joints of the wiring clips, special temperature measu...

Problems solved by technology

[0003] 1) Ordinary wire clips and bergamot type wire clips have a lot of consumables, and the utilization rate of conductive materials is low

[0004] 2) During the long-term use of the terminal clip, the contact surface is prone to oxidation and corrosion, resulting in poor contact. At high temperature, the terminal clip expands, and the cable clip is separated from the conductive rod, which cannot be self-healing

[0005] 3) When inspecting the junction of the wiring clips, it is necessary to use a special temperature measuring device to detect the temperature of the connecting wire clips, which is inconvenient to operate and increases the difficulty of the inspection work
