Abstract

The invention discloses nitrogen filling vacuum pressure impregnation equipment and method. The equipment comprises a nitrogen preparation device, a paint impregnating vessel, a vacuum unit, a paint storage tank and an exhausting and recovering system. The nitrogen preparation device is connected with the paint impregnating vessel through a pressurizing pipe, and a pressurizing valve is arranged on the pressurizing pipe. The paint impregnating vessel is connected with the vacuum unit through a vacuum pipe, and a vacuum valve is arranged on the vacuum pipe. The bottom of the paint impregnating vessel is connected with the bottom of the paint storage tank through a paint conveying pipe, and a paint conveying valve is arranged on the paint conveying pipe. The paint impregnating vessel is connected with the exhausting and recovering system through an exhausting pipe, and an exhausting valve is arranged on the exhausting pipe. The technical problems that existing vacuum pressure impregnation processes are not good in impregnation effect and high in using cost, output pressure is not easy to control, and solvent waste and environment pollution are liable to occur are solved.

Description

technical field [0001] The invention relates to the field of process equipment manufacturing in the electric power industry, in particular to a nitrogen-filled vacuum pressure impregnation (VPI, Vacuum Pressure) applied to the production process of electrical appliances and electrical materials such as high-voltage motors, transformers, power capacitors, and paper-insulated high-voltage power cables. Abbreviation of Impregnation) equipment and method. Background technique [0002] Vacuum pressure impregnation, also known as VPI, is an important process technology in the production process of high-voltage equipment and electrical materials. After VPI treatment, the insulation performance of the device will be greatly improved. Using the vacuum pressure impregnation process to insulate the high-voltage motor can greatly improve the insulation effect of the motor, so it has always been greatly valued by the domestic and foreign motor and high-voltage equipment industries.
