Since the 20th century, with the development of industrial electrification, power capacitors have also gone through ups and downs for decades.
First generationPower capacitorsRapeseed oil or salad oil is generally used as the filling medium, which is generally called oil-type power capacitor, but the oil-type power capacitor will deform the shell due to thermal expansion during use, resulting in oil leakage at the seal, which will cause damage to other components when the environmental pollution is serious. In order to solve the environmental pollution problem of the first generation of liquid capacitors, the second generation of power capacitors uses relatively dry microcrystalline wax as the medium, which is a generation of products from oil power capacitors to dry power capacitors. The third-generation power capacitor uses dry-type silicone oil as the medium, and the dry-type silicone oil becomes a solid state after heat setting, because it is treated by heat setting technology, so there will be no liquid outflow when the electrical load is large, and the capacitor is overheated due to frequent switching. But the service life is relatively short. **The power capacitor is filled with the substrate of German Chuangspu, and the power capacitor has a special protective medium nitrogen, which is filled with degradable soft resin, which has the advantages of relatively small size, light weight, and can avoid environmental pollution, and is the mainstream product of power capacitors in the future.
