Automatic control trolley capable of self-cooling for live-line gas supplementation of SF6 (sulfur hexafluoride) equipment

Abstract

The invention discloses a self-cooling SF6 equipment live-line air supply automatic control trolley which comprises a control trolley body, a machine box is fixedly installed on the left side of the top of the control trolley body, heat absorption pipes are fixedly installed on the two sides of the machine box, an air pressure box is connected to the upper sides of the bottoms of the heat absorption pipes through pipelines, and an air pressure plate is slidably connected to the interior of the air pressure box. A top pipeline of the air pressure plate is connected with a reset spring, the other end of the reset spring is fixedly connected to the inner wall of the top of the air pressure box, the top of the air pressure plate is fixedly connected with an air pressure rod, the two sides of the air pressure rod are fixedly connected with Z-shaped connecting rods, and the other ends of the Z-shaped connecting rods are fixedly connected with sliding blocks. A sliding rheostat is slidably and electrically connected to the left side of the sliding block, a fan is electrically connected to the top of the sliding rheostat, and a one-way exhaust hole is formed in the top of the case.

Description

technical field [0001] The invention relates to the technical field of control hosts, in particular to a self-cooling SF6 equipment charged gas automatic control trolley. Background technique [0002] SF6 electrical equipment has the characteristics of large capacity, many times of operation, stable and reliable operation, and convenient maintenance. The SF6 gas is prone to leakage, which reduces the gas pressure in the SF6 equipment, resulting in a significant drop in the insulation and arc extinguishing capabilities of the SF6 equipment, and may even cause serious accidents such as equipment explosion. [0003] However, the existing SF6 equipment electrified gas supply automatic control trolley control host does not have the function of automatic cooling and cooling. The control host will become hot under long-term work. In severe cases, it may even cause an explosion, burn the equipment, and bring unpredictable safety hazards. , Therefore, it is necessary to design a sel...

[0002] SF6 electrical equipment has the characteristics of large capacity, many times of operation, stable and reliable operation, and convenient maintenance. The SF6 gas is prone to leakage, which reduces the gas pressure in the SF6 equipment, resulting in a significant drop in the insulation and arc extinguishing capabilities of the SF6 equipment, and may even cause serious accidents such as equipment explosion.

[0003] However, the existing SF6 equipment electrified gas supply automatic control trolley control host does not have the function of automatic cooling and cooling. The control host will become hot under long-term work. In severe cases, it may even cause an explosion, burn the equipment, and bring unpredictable safety hazards. Therefore, it is necessary to design a self-cooling SF6 equipment with strong practicability and automatic cooling of the SF6 equipment.
