The invention relates to a power electrical device with an insulation performance self-recovery function and a use method thereof. According to the prior art, the insulation medium of a power electrical device, which is made of epoxy resin cannot be recovered and needs to be replaced after broken down; and since the insulation medium is difficult to replace, the problem that the whole device is possibly damaged and even scrapped can be brought about, while, with the power electrical device adopted, the problem in the prior art can be solved. The power electrical device includes a shell and a plurality of electrical elements arranged in the shell; paraffin is arranged between the plurality of electrical elements and between the electrical elements and the shell; and the breakdown strength of the paraffin is greater than field strength of the electrical elements.
Description
Technical field[0001]The invention belongs to the application of dielectric in the field of electrical equipment insulation, and in particular relates to a power electrical equipment with self-recovery insulation performance and a use method thereof.Background technique[0002]In the research and development of power and electrical equipment, high-voltage electrical equipment, gas switches and other products, the insulation between electrical components and equipment is often involved, and the insulation characteristics directly determine the performance and reliability of the product. The widely used solid dielectrics with volume insulation (such as epoxy resin, etc.) usually have high hardness and melting point, and have strong adhesion to the device. Once the internal components are broken down, the insulation cannot be restored. Replace the insulation The difficulty of the media is also very large, which usually leads to the scrapping of the entire equipment, restricts repeated ap...
