High temperature resistant overvoltage protector protection cover

Abstract

The invention relates to a high temperature resistant overvoltage protector protection cover. The formula of the high temperature resistant overvoltage protector protection cover consists of, by weight, 50-85 parts of polyethylene, 5-14 parts of antioxidant, 2-5 parts of graphite, 4-14 parts of thermoplastic resin, 6-9 parts of a plasticizer, 5-7 parts of activated carbon, 9-14 parts of dibutyl phthalate, 4-7 parts of polylactic acid, 3-8 parts of polystyrene, 2-6 parts of hydroxymethyl fatty amine, 4-16 parts of corrosion resistant resin, 6-9 parts of nitrile rubber, 5-9 parts of acrylic resin, 3-8 parts of corundum, 5-9 parts of silicon carbide grains, 3-5 parts of zinc oxide, 6-18 parts of aluminum oxide and 3-9 parts of copper oxide.

Description

technical field [0001] The invention relates to the technical field of overvoltage protectors, in particular to a high temperature resistant overvoltage protector protective cover. Background technique [0002] Overvoltage protectors are mainly used to protect the insulation of electrical equipment such as generators, transformers, vacuum switches, busbars, and motors from overvoltage damage. [0003] In the prior art, during the use of the overvoltage protector, there is a high requirement for the external ambient temperature. In the high temperature environment, the overvoltage protector is difficult to work, and it is easy to burn out after working for a period of time. Phenomenon occurs, thus losing a lot of resources and costs. In order to be able to work in a high temperature environment, people will add a protective shell to the outside of the overvoltage protector, but due to the material problem of the protective shell, the overvoltage protector cannot last for a lo...

[0003] In the prior art, during the use of the overvoltage protector, there is a high requirement for the external ambient temperature. In the high temperature environment, the overvoltage protector is difficult to work, and it is easy to burn out after working for a period of time. Phenomenon occurs, thus losing a lot of resources and costs. In order to be able to work in a high temperature environment, people will add a protective shell to the outside of the overvoltage protector, but due to the material problem of the protective shell, the overvoltage protector cannot last for a long time. work in a high temperature environment, which brings great trouble to the user
