Problems solved by technology

[0005] The present invention aims to solve the problem that the sulfur hexafluoride sample gas of the equipment to be tested may be mixed with the original gas in the collection bottle in the prior art, causing sample pollution and reducing the accuracy of the test, and the problem of sampling and collecting the sulfur hexafluoride gas in the prior art The operation is cumbersome, and the original gas needs to be blown out with the sulfur hexafluoride gas of the equipment. The sulfur hexafluoride gas will leak with the original gas. The sulfur hexafluoride sample gas contains toxic gas, which threatens the health and life safety of the experimenters, and Sulfur hexafluoride gas is a greenhouse gas, and it is a problem of environmental pollution, and then a sulfur hexafluoride gas collection device is proposed

Abstract

The invention discloses a sulfur hexafluoride gas collecting device, relates to a gas collecting device, and aims at solving the problems in the prior art that a sulfur hexafluoride sample gas of to-be-detected equipment may be mixed with an original gas in a collecting bottle, so that pollution to the sample is generated, and the test accuracy is reduced; the original gas is blown out by using the sulfur hexafluoride gas of the equipment, the sulfur hexafluoride gas containing toxic gas leaks along with the original gas, so that the health and the life safety of an experimenter are threatened; the sulfur hexafluoride gas belongs to a greenhouse gas, resulting in damage to the environment. The device comprises an intake pipe, an intake valve, a pressure gage, a first bottle body, a second bottle body, a vent valve, a vent pipe, a piston mechanism, two flanges and a plurality of connectors. The sulfur hexafluoride gas collecting device is used when the sulfur hexafluoride gas is collected.

Description

technical field [0001] The invention relates to a gas collection device, in particular to a sulfur hexafluoride gas collection device. Background technique [0002] As an excellent insulating medium and arc extinguishing medium, sulfur fluoride gas is widely used in various high-voltage electrical appliances, including sulfur hexafluoride gas-insulated circuit breakers, GIS, transformers, transformers, power cables, etc. Strict quality control of sulfur hexafluoride gas used in power equipment. Generally, the chemical properties of sulfur hexafluoride gas are very stable, it does not burn in the air, does not support combustion, and does not react with water, strong alkali, ammonia, hydrochloric acid, sulfuric acid, etc.; it is chemically inert at room temperature, rarely melts in water, slightly melts Yu alcohol. It does not chemically interact with metals and other organic materials commonly used in electrical equipment. However, under the action of high-power arc, spar...
