Problems solved by technology

Although the current vacuum pressure impregnation equipment has good performance, it is impossible to avoid the influence of the insulating varnish remaining in the impregnation tank on the vacuum degree every time the vacuum is pumped, because the insulating varnish contains about 30% styrene or other diluents, and styrene or other diluents are flammable and explosive substances, the explosion limit range is 1-7%, and the spontaneous ignition point is 460°C
When there is more insulating varnish left in the varnish dipping tank, there will be more styrene or other diluents in the insulating varnish. When vacuuming, there will be more flammable and explosive gases entering the vacuum u

Abstract

The invention relates to explosion-proof vacuum pressure impregnated insulation device and its process which is used in high-tension motor winding loop impregnated insulation paint, it characterized in that: condensator connected with refrigerator is set on the vacuum tube between the impregnating vessel and vacuum set, and collecting vessel is set on bottom of the impregnating vessel, one end of the collecting vessel is connected with the impregnating vessel, the another end is connected with the paint pipelines of storing vessel via transferring valve and returning valve. Using the device and the process, the remained insulation paint and dissolvent in the impregnating vessel can be solved, when the vacuum set vacuumizes the impregnating vessel, the explosive fuel phenylethene deflocculating agent can not be sucked to the vacuum set to gel and jam, it possesses practical effects of explosion-proof, safe reliability, saving raw material.

Description

technical field [0001] The invention belongs to the technical field of pressure vessels, in particular to an explosion-proof vacuum pressure impregnated insulation device and a process method thereof for impregnating insulating varnishes for winding coils of high-voltage motors. Background technique [0002] The voltage generated by the generator can only be used through the grid transmission and sorting. Now, users combine the development needs of large drag and high power, and directly connect the motor to the transformer of 6Kv and above, which can reduce the loss of the line, and also reduce the re-investment of the low-voltage transformer and its auxiliary facilities. For this reason, high-voltage generators and electric motors of 6KV and above are popularized and applied in large areas. Since high-voltage motors are subject to high voltage and high current, in order to improve the withstand voltage level of high-voltage motor winding coils, vacuum pressure impregnatio...
