Novel environment-friendly insulation medium fast charging and discharging device and gas preparation method

Abstract

The invention discloses a novel environment-friendly insulation medium fast charging and discharging device and a gas preparation method. The device comprises a liquid storage tank (9) and a gas storage chamber (8), and is characterized in that a heating module (14) is arranged in a bottom casing of the liquid storage tank (9); the gas storage chamber (8) and the liquid storage tank (9) are respectively connected with a gas distribution device (6) through a second gas outlet pipe (25) and a first gas outlet pipe (24); the gas distribution device (6) is connected with gas insulation equipment (1) through a third gas outlet pipe (2). The device and the method solve the technical problems that in the prior art, C6F12O is used as environment-friendly insulation gas of medium-low-pressure equipment, the precise C6F12O and CO2 mixing ratio cannot be realized; the comprehensive local discharge performance and breakdown performance are seriously influenced; in addition, when the C6F12O and CO2gas mixed charging is used, the mixing ratio cannot be precisely controlled; the mixed charging is difficult, and the like.

Description

technical field [0001] The invention belongs to a gas filling technology in a novel environment-friendly electrical equipment, and in particular relates to a novel environment-friendly insulating medium rapid charging and discharging device and a gas configuration method. Background technique [0002] SF 6 With its excellent insulation performance, it is widely used in power equipment of various voltage levels, but due to SF 6 It has a serious greenhouse effect and is listed as one of the six major greenhouse gases in the Kyoto Protocol. With the gradual awakening of people's awareness of environmental protection, the international community has imposed restrictions on SF 6 The voice of using it is getting higher and higher, and some countries and regions have also begun to use SF 6 Levy environmental protection tax. [0003] Therefore as the current SF 6 It is necessary to find a new type of environmentally friendly insulating gas that has both insulating properties an...
