Abstract

The invention provides a gas pressing device for improving oil gas fusion rate. The gas pressing device comprises a tube body, a connection base, a top cover, a piston, a turbine, an observation window, an oil feeding / taking port, a gas inlet, a gas transmission pipeline and a pressure sensor. The top surface of the piston is provided with a ring groove for holding a heavy object; and the test endof the pressure sensor extends between the piston and the bottom surface of the tube body. Gas-liquid contact area is increased by utilizing the long spiral gas transmission pipeline; gas-liquid two-phase disturbance degree is increased through the built-in small turbine, thereby reducing gas-liquid membrane surface resistance and increasing gas-liquid interface size; meanwhile, gas-liquid interface pressure is increased by utilizing the bearing piston, so that dissolution rate of fault characteristic gases in transformer oil can be improved effectively; and the side wall of the tube body isequipped with the pressure sensor, so that pressure of gas in the tube body can be monitored in real time, and gas dissolution amount can be calculated conveniently.

Description

technical field [0001] The invention relates to a gas dissolving device, in particular to a gas compressing device for increasing the fusion rate of oil and gas. Background technique [0002] Large oil-immersed power transformer is the core equipment of power transmission and transformation system. When it fails or is damaged, it will threaten the stability and safe operation of the power grid, and even cause serious safety accidents, which will bring great harm to people's lives and property. [0003] The transformer oil and insulating paper in the oil-paper insulation system of oil-immersed power transformers will crack and produce some fault characteristic gases, such as H 2 , CO, CO 2 、CH 4 、C 2 h 6 、C 2 h 4 、C 2 h 2 etc. These gases will be dissolved in the transformer oil. Accurate detection of the characteristic gas dissolved in the transformer oil and the dissolved amount of the gas is the key to realize the early latent fault diagnosis of the oil-immersed po...
