Sealing gas sampling apparatus

Abstract

The invention discloses a sealing gas sampling apparatus, including an adapter, a first electromagnetic valve, a second electromagnetic valve, a gas container, a vent valve and a minisize high-pressure air pump. One end of the adapter is provided with a connecting column and a convex column and the other end is provided with an air inlet and an air outlet. The air outlet of the adapter is connected with the inlet of the first electromagnetic valve. The outlet of the gas container is connected with the inlet of the minisize high-pressure air pump. The outlet of the minisize high-pressure air pump is respectively connected with the inlet of the second electromagnetic valve and the vent valve via a tee joint. The outlet of the second electromagnetic valve is connected with the air inlet of the adapter. An interface is arranged on the gas container. The sealing gas sampling apparatus can sample the sealing gas. The gas passing through the sampling and analysis instrument can be charged to the electrical apparatus or the gas tank timely to realize the effective sampling of the measured gas, thus benefiting environmental protection and avoiding the economic loss.

Description

technical field [0001] The invention relates to a sealed gas sampling realization device for sampling the sealed gas in electrical equipment or a gas storage tank. Background technique [0002] Sampling and testing the sealed gas in electrical equipment or gas storage tanks is a work that often needs to be dealt with in practice. For example, in practice, it is often necessary to sample and detect sulfur hexafluoride gas in electrical equipment or gas storage tanks. Sulfur hexafluoride gas is a colorless, odorless, non-toxic, high-insulating gas, which is generally used as an insulating gas in various high-voltage electrical equipment. However, due to the huge damage of sulfur hexafluoride to the environment Moreover, the price of sulfur hexafluoride gas itself is relatively high, and the requirements for sulfur hexafluoride gas are very high during the operation of high-voltage electrical equipment. The operation of on-site equipment needs to pay attention to various chang...

Problems solved by technology

This method is currently adopted by many sites and many gas sampling and analysis instruments. The gas sampling method is very simple, but its disadvantages are many, mainly: A. Since the sampling gas is directly discharged into the atmosphere, the damage to the environment is very serious; B. Cause the loss of sulfur hexafluoride gas in the equipment, which may cause serious consequences to the safe operation of the equipment; C. The price of sulfur hexafluoride gas itself is relatively high, causing great economic losses

[0006] Both of the above two methods have serious problems, and the above methods are only suitable for intermittent periodic inspection gas sampling analysis, and cannot solve the problem of online gas sampling in the electrical equipment under inspection. Monitoring and analysis, and with the increasing use of electrical equipment using sulfur hexafluoride gas, monitoring its safe operation is becoming more and more important. It is considered that many It is an extremely effective method in the operation safety monitoring method, and the exploration of a new effective and safe gas sampling method has been focused on for a long time, but so far there has not been a realization method and a realization device that can solve the above problems
