Vacuum ultrasonic degassing device for portable transformer oil photoacoustic spectrum detection device

Abstract

The invention discloses a vacuum ultrasonic degassing device for a portable transformer oil photoacoustic spectrum detection device. The vacuum ultrasonic degassing device comprises an oil chamber and is characterized in that the oil chamber is internally provided with a piston; the piston is connected with a stepping motor; an oil inlet pipeline of the oil chamber is matched with an injector; a solenoid valve is further arranged on the oil inlet pipeline; a gas outlet pipeline is arranged at the top end of the oil chamber; the gas outlet pipeline is connected with an in-oil gas concentration detection device through a three-way solenoid valve; a liquid level switch is further arranged at the connection part of an oil outlet pipeline and the oil chamber; an ultrasonic vibration device is further arranged under the oil chamber; and a central controller is further matched with the stepping motor, the solenoid valve, the three-way solenoid valve, the in-oil gas concentration detection device, the liquid level switch and the ultrasonic vibration device.

Description

technical field [0001] The invention relates to a degassing device, in particular to a vacuum ultrasonic degassing device used in a portable transformer oil photoacoustic spectrum detection device. Background technique [0002] The traditional degassing device has the following disadvantages during use: 1. The oil-gas separation efficiency is low, and the gas in the oil cannot be completely separated, which directly leads to large errors in the analysis and measurement of the gas in the transformer oil; 2. Oil-gas separation The operation time is long, which affects the service life of the oil-gas separation device; 3. The degassing method used in traditional gas chromatography cannot meet the requirements of photoacoustic spectroscopy measurement. Based on the above reasons, there is a need for a new type of degassing device that can solve these problems. Contents of the invention [0003] The present invention aims to solve the above-mentioned deficiencies in the prior ...
