Electrified automatic gas supplementing device for SF6 equipment

Abstract

The invention discloses an electrified automatic gas supplementing device for SF6 equipment, belongs to the technical field of electrician equipment maintenance, and is used for moving a gas cylinderto supplement gas. The electrified automatic gas supplementing device comprises a frame body, a gas supplementing device, a crawler belt mechanism, a power supply with a handle and a control panel. Byarranging an interlayer A for inserting the power supply, an interlayer B for placing the bottom of the gas cylinder, a bandage for flexibly fixing the middle part of the gas cylinder and an interlayer C for placing the gas supplementing device on the frame body, a worker can flexibly assemble the power supply, the gas cylinder and the gas supplementing device, so that the time consumed by early-stage preparation of emergency operation is reduced; and the crawler belt mechanism and ladder climbing wheels are additionally arranged at the bottom of the frame body, manual pushing is replaced, the stair climbing function is achieved, and the technical problems that the worker moves an SF6 gas cylinder far away, moving is difficult, and the working intensity is high are solved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment maintenance, in particular to an automatic gas supply device for SF6 equipment when it is charged. Background technique [0002] SF 6 Electrical equipment has the characteristics of large capacity, many operations, stable and reliable operation, and convenient maintenance. It is one of the mainstream equipment in substations at present. SF 6 Gas leaks easily, making SF 6 The gas pressure in the equipment decreases, causing SF 6 The insulation and arc extinguishing capabilities of the equipment are greatly reduced, which may even cause serious accidents such as equipment explosion. [0003] Considering SF 6 Due to the safety requirements of electrical equipment, the substation maintenance team needs to frequently carry out air replenishment work on electrical equipment. Often, due to the urgency of the substation maintenance situation, the staff needs to prepare urgently, and the ...

[0002] SF 6 Electrical equipment has the characteristics of large capacity, many operations, stable and reliable operation, and convenient maintenance. It is one of the mainstream equipment in substations at present. SF 6 Gas leaks easily, making SF 6 The gas pressure in the equipment decreases, causing SF 6 The insulation and arc extinguishing capabilities of the equipment are greatly reduced, which may even cause serious accidents such as equipment explosion

[0003] Considering SF 6 Due to the safety requirements of electrical equipment, the substation maintenance team needs to frequently carry out air replenishment work on electrical equipment. Often, due to the urgency of the substation maintenance situation, the staff needs to prepare urgently, and the pre-assembly preparation work of the existing equipment is complicated; large Some substations are geographically far away from the headquarters, and the staff move SF 6 The gas cylinder is difficult, the work intensity is high, and the gas replenishment work is usually carried out temporarily and urgently. The gas replenishment equipment cannot be prepared in advance, and the temporary preparation is time-consuming; the gas replenishment process requires the cooperation of multiple people, always pay attention to the air pressure of the equipment, and adjust the trachea multiple times The valve, the inflation efficiency is extremely low, and the output gas pressure of artificial inflation and the pressure inside the equipment are unstable, SF 6 The equipment pressure is too low to affect the normal operation of the equipment, SF 6 Equipment pressure is too high, there is a risk of safety accidents
