氧化锌避雷器
从属类别:高压系列   

◆ 基本原理 Keyston

氧化锌避雷器是目前国际最先进的过电压保护器。由于其核心元件采用氧化锌电阻片,与传统碳化硅避雷器相比,改善了避雷器的伏安特·眭,提高了过电压通流能力,从而带来避雷器特征的根本变化。当避雷器在正常工作电压下,流过避雷器的电流仅有微安级,当遭受过电压时,由于氧化锌电阻片的非线性,流过避雷器的电流瞬间达数千安培,避雷器处于导通状态,释放过电压能量,从而有效地限制了过电压对输变电设备的侵害。

The zinc oxide arrester is the most advanced over—voltage protector in the world.Due to make the resistor disc of core component mainly
adopt zine oxide arrester.Compared with the conventional silicon carbide arrester,this presciption of the product improves greatly the volt—Ampere characterisics of the resistor disc and increased through—current capabil—ily at over-voltage so as to bring a radical changes for the characteristics of the a rresters.Under the circumstance of no rmal ope rating voltage,the current through the arrester is just on microampere degree. When suffered from over—voltage,the arrester’s excellent nonlinear characte ristics will make the current through the arrester increase to several thousand amperse,while the arrester will be under the circulating state and release over—
voltage energy so as to protecting the power thansmission equipmentsagainst the damage caused by the over—voltage

YW、HYW型氧化锌避雷器 Zinc Oxide Arreste

 

组合式过电压保护器
用途
RSB组合式过电压保护器是一种新颖的过电压保护器,主要用于35KV及以下电力系统中,保护变压器、开关、母线、电动机、并联补偿电容器等电气设备,可限制大气过电压及各种真空断路器引起的操作过电压,对相地和相间的过电压均能起到可靠的限制作用。
概述
RSB三相组合式过电压保护器由四只避雷器组成图示四星型接法,从而使各相地、相间的过电压都得到保护。由于结构上的巧妙配合,使一台避雷器起到6只避雷器的作用。同时克服了简单的三只避雷器星形接法不能更好保护相间过电压的缺点。RSB三相组合式过电压保护器可以是有串联间隙型,也可以是无间隙型。
