Vacuum pressure lacquer-dipping cluster device

Abstract

The invention provides a vacuum pressure lacquer-dipping device which comprises a vacuum unit, a lacquer-dipping tank and a lacquer-storing tank connected with the lacquer-dipping tank, wherein the bottom of the lacquer-dipping tank is communicated with the bottom of the lacquer-storing tank through a lacquer-conveying pipeline; a lacquer-conveying valve is arranged on the lacquer-conveying pipeline; the lacquer-dipping tank is respectively communicated with the vacuum unit, an air compressor and a nitrogen tank through a communicating valve; an infrared heating device is mounted in the lacquer-dipping tank; the vacuum pressure lacquer-dipping device is characterized in that: the vacuum unit is provided with a roots pump, a first mechanical pump and a second mechanical pump; the first mechanical pump and the second mechanical pump are serially connected with the roots pump; and a low-temperature catcher is mounted on a vacuumizing pipeline between the lacquer-dipping tank and the vacuum unit. A vacuum system provided by the invention is used for quickly vacuumizing till the pressure is below 0.1Pa. The low-temperature catcher is arranged in the pipeline, so that the risk in styrene explosion during the preheating or vacuumizing process of the system is effectively prevented.

Description

technical field [0001] The invention relates to a vacuum pressure impregnation equipment, more specifically, the invention relates to a cluster equipment for vacuum pressure impregnation. Background technique [0002] Vacuum pressure impregnation, also known as VPI process, VPI vacuum pressure impregnation equipment is an important process equipment in the production process of high-voltage motors, transformers, power capacitors and paper-insulated high-voltage power, cables and other electrical appliances and electrical materials. Good insulation performance, lower temperature rise, higher efficiency, and can increase mechanical strength, solve the loosening phenomenon during operation, prevent insulation failures such as short circuits, improve the moisture-proof ability of the device, prolong the life of the device, and improve its electrical resistance. The equipment generally consists of a paint soaking tank, a paint removal coffin, a vacuum pumping system, a compressed...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the problems of discontinuous processes and low efficiency of the pressure impregnation equipment in the prior art, the present invention proposes a cluster equipment for vacuum pressure impregnation. The system is distributed around the shared vacuum chamber. According to the sequence steps of the vacuum pressure impregnation process, each subsystem is set up at one time, and then the continuous work of each link of impregnation can be realized, which saves time and improves production efficiency.
