With the development of urban and rural power grid construction and transformation projects in China, the application market of the electric SF6 technology in China is started comprehensively. Therefore, the usage standard and safety of the SF6 gas are of great concern. Since the SF6 gas is partially decomposed under the action of high-voltage arc or at high temperature, the decomposed product is often extremely toxic and even in trace amount, can cause human non-life. When the leakage occurs in the process of indoor switching by taking SF6 gas as an insulating and arc extinguishing medium, the leaked SF6 gas and the decomposition products thereof can accumulate in the indoor lower-layer space to cause local oxygen deficiency and carry toxicity, thereby forming serious danger for the life safety of workers entering the indoor space.
In order to ensure the normal operation of the power system, the test team of the power supply bureau needs to regularly go to the substation to perform conventional sampling tests on the SF6 gas, such as leak detection, micro-water tests and the like, so as to find out the potential safety hazard in time. However, since the maintenance work of the operating personnel who newly enter the team is not familiar, if the operating personnel directly arrive the equipment to take samples, the equipment of the transformer substation is easy to leak or damaged due to improper operation, and meanwhile, the SF6 on the equipment is very dangerous to directly use for gas taking teaching, because the electric arc is generated, the decomposition products exist, and the life danger exists after the toxic decomposition products are inhaled by the human body.
