Abstract

The invention discloses a dehydration, degassing and storage device for insulating oil in the laboratory. The device comprises a vacuum pump, a nitrogen bag, a vacuum glass bottle, a constant-temperature magnetic stirrer and an oil storage tank, wherein the vacuum glass bottle is arranged on the constant-temperature magnetic stirrer and internally matched with a magnetic stirring rotor, an exhaustport of the vacuum glass bottle is connected with the vacuum pump and the nitrogen bag, an exhaust pipeline of the oil storage tank is connected with the vacuum pump and the nitrogen bag, an oil outlet of the vacuum glass bottle is connected with an oil inlet pipeline of the oil storage tank, and an oil taking pipeline is arranged at the bottom of the oil storage tank. The invention also discloses a dehydration, degassing and storage method for the insulating oil in the laboratory. The dehydration, degassing and storage of the insulating oil can be completed by only one set of simple equipment, and the whole process is isolated from air, so that the dehydration, degassing and storage device has the advantages of low equipment consumption, easiness in construction, simplicity in operation,small occupied space and good dehydration and degassing effects, and the influence of excessive moisture or dissolved gas in the insulating oil on simulation experiment results such as breakdown andpartial discharge can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of insulating oil pretreatment, in particular to a laboratory insulating oil dehydration and degassing storage device and a dehydration and degassing storage method. Background technique [0002] Insulating oil is an important liquid insulating medium in power system. It is widely used in high-voltage power equipment such as power transformers, power capacitors, reactors and oil-filled cables. Insulation, heat dissipation and cooling, and arc suppression. [0003] The insulating oil that has just left the factory will absorb gas and moisture during packaging, transportation and storage management. The more aromatic components in the insulating oil, the higher the moisture absorption, and the existence of polar molecules in the oil will also increase the moisture absorption of the insulating oil. The increase of moisture in the insulating oil will have a serious impact on the electrical and physical and che...
