Embodiment Construction

[0014] A shunt device for treating the heat generated by the gate of a horizontal rotary high-voltage isolating switch with electricity, including a self-operated isolating switch contact finger 1 and a horizontally arranged copper bar 2. There are a number of holes on both sides of the copper bar 2. The contact finger 1 of the self-operated isolating switch is connected with a copper bar 2; a pair of hooks 3 are arranged on the upper surface of the copper bar 2.

[0015] The connecting piece 4 is an adjustable fastening bolt; the contact fingers 1 of the isolating switch are symmetrically arranged around the center of the copper bar 2 .

[0016] The copper bars 2 are arranged in parallel and fixed to each other. The hook 3 is made of aluminum material.

[0017] The treatment of heat generation at the gate is generally a power failure treatment. The power failure treatment is to replace or polish the contacts and fingers at the gate of the isolating switch, fasten the joints,...

Abstract

The invention discloses a shunting device for handling heating of the gate of a horizontal-rotation type high-voltage isolating switch in an electrifying mode, and belongs to the technical field of handling of heating of the gate of the isolating switch. The gate and conducting rods of the isolating switch are exposed to the air and can emit heat easily under the influence of wind, rain, snow, dirt, condensates, ice and heavy frost. The shunting device for the gate of the horizontal-rotation type high-voltage isolating switch can lower the temperature of the gate effectively and is flexible and convenient to operate. According to the technical scheme, the shunting device for handling heating of the gate of the horizontal-rotation type high-voltage isolating switch in the electrifying mode comprises weight-loaded contact fingers and connection copper bars. The weight-loaded contact fingers are connected with the connection copper bars through adjustable bolts, adjustment is carried out according to the cross section of the conducting rods of the heating isolating switch before short circuit operation so as to guarantee contact pressure, and hooks are fixed. The shunting device for the gate is reliably connected with the gate of the heating isolating switch in parallel through an isolating operation rod and the hooks. The shunting device is suitable for electric systems.

Description

technical field [0001] The invention relates to electric power equipment, in particular to a shunt device for treating heat generated at a gate of a horizontal rotary high-voltage isolating switch with electricity. Background technique [0002] High-voltage isolating switches, because their key parts such as conduction, insulation, and transmission are exposed to the air, especially outdoor high-voltage isolating switches, can withstand the effects of wind, rain, snow, pollution, condensation, ice and thick frost, etc. Equipment has many defects and has a great impact, among which heat defects are the most concentrated. In recent years, with the improvement of the equipment of the manufacturer and the maintenance of the maintenance unit, especially since the live maintenance of the disconnector gate, the heating defects of the disconnector have been greatly reduced, and the health level of the equipment has been improved. However, there are still some gates of isolating swi...
