Air make-up working vehicle with gas remaining amount control function

Abstract

The invention provides an air make-up working vehicle with a gas remaining amount control function. The air make-up working vehicle comprises a frame, wherein vehicle wheels used for walking are arranged on the frame; a weighing sensor is further arranged on the frame; the top of the weighing sensor is provided with a weighing platform; the frame is further provided with a luggage carrier used for bearing a gas cylinder; when the air cylinder is placed at the luggage carrier, the gas cylinder is not in contact with the weighing platform. The air make-up working vehicle is simple in structure, convenient in use, and capable of safely, fast and conveniently transporting the gas cylinder, thus, eliminating the potential safety hazards during a gas cylinder transportation process; by adopting the air make-up working vehicle, the gas cylinder can be fast and conveniently, accurately weighed at any time, so that SF6 gas remaining amount in the gas cylinder can be known, and further the air compensation for gas-insulated electrical equipment each time can be mastered, and production frontline data are provided for lean management of the gas-insulated electrical equipment, and a technological means is provided for lean management of a GIS air chamber.

Description

technical field [0001] The present invention relates to, in particular, relates to an air replenishing work vehicle with the function of controlling the remaining amount of gas. Background technique [0002] With the rapid development of the power grid construction of the State Grid Corporation of China, the proportion of gas replenishment work for gas-insulated electrical equipment such as GIS in the daily maintenance work is gradually increasing. The existing gas replenishment method is to manually replace the SF 6 The gas cylinder (hereinafter referred to as the gas cylinder) is transported to the vicinity of the equipment, and then the gas is replenished, but the above methods have the following problems in the gas replenishment process: [0003] 1. The gas remaining in the cylinder remains high. When the GIS equipment in the substation is working, the SF of the high-voltage switch GIS gas chamber is required 6 The gas pressure is 0.6-0.7Mpa, and the working pressure o...

AI Technical Summary

Problems solved by technology

However, the lack of SF 6 Accurate controller of remaining gas

[0005] 2. Security risks

Once the gas cylinder falls, the violent collision will cause the pressure in the gas cylinder to increase, and there is a risk of cracking and explosion

Once leaked, SF 6 When the gas is mixed with low sulfur fluoride, hydrogen fluoride, especially sulfur decafluoride, it is highly toxic, and if inhaled too much, it will cause breathing difficulties and even endanger life
