Problems solved by technology

[0002] The impregnating agent of the capacitor acts as a liquid insulating medium to fill the gap between the solid medium and improve the dielectric strength. The aging performance is closely related to the gas washing performance under the electric field. At present, the performance of the capacitor impregnating agent is not high, and the service life is low. Many impregnating agents are easy to cause corrosion to the capacitor plate, which further affects the life of the capacitor under high electric field.
