HY10WZ-108/280W Composite jacket, Zinc Oxide Aarrester

Product Introduction

HY10WZ-108/281 Zinc Oxide Arrester is used to protect AC electrical equipment in power plants and substations from damage from atmospheric overvoltage and operating voltage. Lightning arrester is a device that protects equipment in substations from lightning shock waves. When the lightning shock wave introduced into the substation along the line exceeds the protection level of the arrester, the arrester will discharge, and the lightning current will be safely introduced into the ground through a good conductor. The grounding device is used to limit the amplitude of the lightning voltage to the lightning shock level of the protected equipment. Keep electrical equipment protected.

HY10WZ-108/281 Zinc Oxide Arrester can be divided into: protection gap, a simpler form of arrester; tubular arrester, – is also a protection gap, but it can extinguish the arc by itself after discharge; and valve arrester, which is a single discharge arrester. The gap is divided into many short series gaps, and at the same time, non-linear resistance is added to improve the protection performance; magnetic blowing arrester: using the magnetic blowing spark gap, the arc extinguishing ability is improved, and it also has the ability to limit internal overvoltage; zinc oxide Surge arrester: utilizes the ideal volt-ampere characteristics of zinc oxide valve plates (high nonlinearity, that is, low resistance characteristics at large currents, limiting the voltage on the arrester, and high resistance characteristics under normal power frequency voltage), with The advantages of no gap, no freewheeling, and low residual voltage can also limit the internal overvoltage and are widely used.
