Overvoltage suppression cabinet arrester valve plate

Abstract

The invention relates to an overvoltage suppression cabinet arrester valve plate. The overvoltage suppression cabinet arrester valve plate is prepared from, by weight, 4-9 parts of kaolin, 3-7 parts of carborundum, 2-4 parts of charcoal active powder, 2-3 parts of nanometer zirconia, 5-6 parts of glass fibers, 3-4 parts of carbon fibers, 2-5 parts of dolomite powder, 4-5 parts of octylphenol polyoxyethylene ether, 3-7 parts of polydimethylsiloxane, 1-2 parts of trimethylhexamethylenediamine, 3-7 parts of solid carbamic acid, 1-2 parts of chlorosilane, 0.3-0.6 part of benzene and 1-1.6 parts of methylbenzene. According to the components of the overvoltage suppression cabinet arrester valve plate, the materials are easy to obtain and low in price, the service life can be prolonged, the anti-aging degree is high, the detects of overvoltage protective elements and devices in a system can be overcome, the overvoltage protection level of the system is promoted, and meanwhile resonance overvoltage and broken wire overvoltage in the system are eliminated.

Description

technical field [0001] The invention relates to the technical field of overvoltage suppression devices, in particular to a valve plate of an arrester for an overvoltage suppression cabinet. Background technique [0002] In the power supply system or in the power supply grid, the phenomenon of overvoltage is very common. If there are no precautions, it can happen at any time, and it can be found at any time. There are many reasons for grid overvoltage. It can be mainly divided into internal overvoltage and lightning overvoltage. Internal overvoltage includes resonant overvoltage and operating overvoltage. Resonant overvoltage occurs frequently in normal operation and is more harmful. [0003] Accidents caused by resonance overvoltage are very frequent, and it may occur in all levels of power grids. Many components in the system are inductive or capacitive, such as power transformers, transformers, generators, and arc suppression coils. , A parallel or series capacitor bank...

Problems solved by technology

[0004] It is precisely because of the long duration of the resonant overvoltage that its harm is also great. In the power system, the resonant overvoltage not only endangers the insulation of electrical equipment, but may also generate continuous overcurrent and blow the fuse or equipment. Affects the working conditions of the overvoltage protection device. Ordinary arresters are often destroyed due to the action under the resonant overvoltage and the arc cannot be extinguished.
