A transport trolley for sulfur hexafluoride gas cylinders

Abstract

The invention discloses a sulfur hexafluoride gas cylinder transportation trolley which comprises a trolley frame, wherein a handle used for being held is arranged at the rear end of the upper portion of the trolley frame, a base used for bearing a gas cylinder is arranged on the lower portion of the trolley frame and provided with a weighing sensor used for measuring the weight of the gas cylinder, the base is further provided with a fixing sleeve matched with the gas cylinder in shape and used for fixing the gas cylinder, an electric heating device and a temperature sensor are arranged in the fixing sleeve, traveling wheels are arranged on the bottom of the trolley frame which is further provided with a display controller, and the display controller is respectively and electrically connected with the weighing sensor, the electric heating device and the temperature sensor. According to the sulfur hexafluoride gas cylinder transportation trolley, the sulfur hexafluoride gas cylinder can be transferred rapidly and flexibly in a workshop, heating and temperature controlling for the gas cylinder are achieved, the weight of the gas cylinder can be monitored in real time so as to bring convenience to mastering of charging and discharging volumes, the structure is simple, convenience and practicality are achieved, operation procedures are simplified, and production efficiency is improved.

Description

technical field [0001] The invention relates to a gas cylinder transportation tool for arc extinguishing gas sulfur hexafluoride, in particular to a sulfur hexafluoride gas cylinder transportation trolley. Background technique [0002] At present, sulfur hexafluoride gas is widely used as an insulating medium for high-voltage circuit breakers, transformers and other power equipment due to its excellent insulation and arc extinguishing properties. Traditional oil-filled equipment is basically replaced by gas-filled sulfur hexafluoride circuit breakers and combined electrical appliances. Sulfur hexafluoride circuit breakers and combined electrical appliances are widely used in power transmission and transformation equipment due to their good safety performance and technical performance; but During the installation and daily maintenance of these devices, it is often necessary to carry out necessary inflation and air supplementation to these electric devices. Therefore, a speci...

AI Technical Summary

Problems solved by technology

[0003] When the liquid sulfur hexafluoride gas in the gas cylinder is filled into the equipment, the liquid state becomes gaseous and absorbs a large amount of heat. If there is no external heat source to continuously replenish heat to the gas cylinder, the sulfur hexafluoride gas in the gas cylinder will remain more. Sulfur hexafluoride gas is expensive, causing a lot of waste, and the inflation efficiency is relatively low; in addition, the amount of sulfur hexafluoride inflated also needs to be determined according to different equipment, so the weight of the gas cylinder must be checked during the refilling process carry out testing

[0004] At present, the general gas cylinder transport trolley cannot meet the requirements of filling sulfur hexafluoride gas cylinders
