Gas cylinder charging assistance device and using method

Abstract

The invention discloses a gas cylinder charging assistance device and a using method. The air cylinder charging assistance device comprises a supporting frame, a hoop, a bearing plate, a weighing base, a heater, a digital display controller and a moving mechanism, wherein the supporting frame is used for supporting a gas cylinder, the hoop is arranged on the first side of the supporting frame andused for tightly holding the gas cylinder, the bearing plate is used for bearing the gas cylinder, the weighing base is arranged on the bearing plate, the heater is used for heating the gas cylinder,the digital display controller is electrically connected with the heater and the weighing base, and the moving mechanism is arranged on the second side of the supporting frame; and the second side ofthe supporting frame is the side opposite to the first side of the supporting frame. According to the gas cylinder charging assistance device, the remaining amount of gas in the gas cylinder can be obtained, the gas is supplemented in time, and the gas cylinder can be transferred to a charging position or a working place easily and rapidly; and meanwhile, gas waste and low efficiency caused by gascondensation due to gas pressure drop in the gas charging process of the gas cylinder can be prevented.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a gas cylinder inflation auxiliary device and a use method. Background technique [0002] Sulfur hexafluoride has good electrical insulation performance and excellent arc extinguishing performance. Its electric strength is 2.5 times that of nitrogen under the same pressure, its breakdown voltage is 2.5 times that of air, and its arc extinguishing ability is 100 times that of air. It is a new generation of ultra-high voltage insulating material superior to that between air and oil. Widely used in large-capacity transformers, closed combination appliances and other electrical equipment. Limited by the manufacturing process, sulfur hexafluoride leakage is common in GIS equipment. Once leakage occurs, the pressure of the air chamber will decrease, which will lead to a decrease in the insulation performance of the GIS equipment, seriously affecting the safe and stable operation of the e...
