Embodiment 1

[0044] Such as figure 1 Shown, the present invention is used for the system of waste transformer oil performance recovery comprising:

[0045] Oil supply pump 2, the pipeline at the inlet end of the oil supply pump 2 is provided with a valve, the other end of the valve is connected to the oil suction filter 1 through the pipeline, the other end of the oil suction filter 1 is provided with an oil inlet pipeline, and the pipeline at the outlet end of the oil supply pump 2 is provided with Valve, the other end of the valve communicates with the heater 3 through a pipeline, the other end of the heater 3 communicates with the first valve device 5 through a pipeline, and a temperature sensor 4 is arranged inside the pipeline between the heater 3 and the first valve device 5;

[0046] Vacuum treatment device, vacuum treatment device comprises vacuum tank 16, condensate tank, vacuum pump 7 and the first oil discharge pump 8, vacuum pump 7 communicates with vacuum tank 16 through pipel...

Embodiment 2

[0070] Such as figure 2 The difference between the present embodiment and Embodiment 1 is that the first valve device 5 and the second valve device 6 are valve groups composed of three electronically controlled valves, by controlling the conduction and switching of different valves in the valve group. Closed to control the flow of waste transformer oil.

Abstract

The invention discloses a system and a treatment method for recovering properties of waste transformer oil. The system comprises an oil supplying pump, a vacuum treatment device, an adsorption regeneration device, a secondary fine filtering device and an electric control cabinet. The system integration is realized by integrating a rough filtering device, the secondary fine filtering device, a heating and temperature rising device, the vacuum treatment device and the adsorption regeneration device, and the integrated system can be used for carrying out rough filtering and secondary fine filtering on the waste transformer oil, dehydrating, degassing and filtering in vacuum, adsorbing, regenerating and filtering, and can be used for carrying out all-directional filtering treatment on the waste transformer oil, so that the cleanness, moisture content, gas content, and indexes including an acid value, dielectric lose, pressure resistance and the like of the waste transformer oil reach new oil standards; the treatment method for recovering the properties of the waste transformer oil, provided by the invention, can be used for carrying out deep treatment by selecting a certain treatment manner according to ageing degrees and impurity components of the waste transformer oil; various treatment manners are integrated through switching working modes, so that the property recovery of the waste transformer oil is realized very well.

Description

technical field [0001] The invention relates to the technical field of transformer oil purification and regeneration treatment, in particular to a system for recovering the performance of waste transformer oil and a treatment method thereof. Background technique [0002] Transformer oil is a kind of natural mineral oil. It is a distillation component in the boiling point range of 280~360°C during petroleum refining. The main components are hydrocarbons, including alkanes, cycloalkanes and aromatics, etc., and a small amount of sulfur , oxygen, nitrogen, etc. Transformer oil is the most important insulation and cooling medium for oil-filled power equipment. It will age during use. The aging process refers to the transformation of transformer oil under the action of physical and chemical factors such as light, heat, oxygen, electric arc, electric field, magnetic field, and radiation. , the physical properties such as color, smell, kinematic viscosity and dielectric loss facto...
