Sulfur hexafluoride gas insulated metal-enclosed switchgear mobile gas filling device

Abstract

The invention discloses a movable air inflation device of a sulfur hexafluoride gas insulation metal enclosed switchgear. The device comprises a base and a gas tank, a first pulley and a second pulleyare arranged on the two sides of the bottom of the base, the first pulley is hinged to the base through a mounting support, the second pulley is connected with the base through a lifting support, a sliding groove is formed in the top of the base, the gas tank is arranged in the sliding groove, a clamp, an air cylinder and a weight sensor are arranged in the sliding groove, a gas outlet connectoris formed in the top of the gas tank, a stand column is arranged on one side of the base, an electric telescopic rod which can stretch out and draw back in the horizontal direction is arranged on thetop of the stand column, a connecting pipe connected with the gas outlet connector is arranged at the bottom of the free end of the electric telescopic rod, a gas supply channel is formed in the electric telescopic rod, one end of the gas supply channel is communicated with the connecting pipe, and the other end of the gas supply channel is connected with a gas supply pipe. According to the device, the gas tank can be conveniently replaced, sulfur hexafluoride gas in the gas tank can be effectively monitored, use is convenient, energy consumption is reduced, the utilization rate of sulfur hexafluoride is imporved, and the waste wasted by sulfur hexafluoride gas is avoided.

Description

technical field [0001] The invention relates to a mobile inflatable device, in particular to a mobile inflatable device for sulfur hexafluoride gas-insulated metal-enclosed switchgear. Background technique [0002] At present, sulfur hexafluoride has become the most important insulating and arc-extinguishing gas medium in the power grid. However, although pure sulfur hexafluoride gas has excellent insulation performance and arc extinguishing performance, its electrical performance will deteriorate significantly as its purity decreases, especially when the gas purity does not meet the specified requirements. . For example, the relevant standards stipulate that the purity of sulfur hexafluoride gas during operation shall not be lower than 97%. During the operation of equipment, sulfur hexafluoride decomposes due to high current breaking and discharge faults, producing oxygen, water and other decomposition compounds, which not only degrades insulating materials, but also corr...

Problems solved by technology

[0003] In the prior art, the replacement of the gas tank is completely done manually by the staff, which is not only time-consuming and laborious, but also difficult to detect whether the sulfur hexafluoride gas in the gas tank is fully used, and there is waste of sulfur hexafluoride gas, which increases energy consumption. consumption
