HY10W,HY5W Polymer type lightning Arrester
 
·Main principle

· Zno lighting arrester is one kind most world advanced over-voltage protector at present,due to its core components of resistanceapply-
ing Zno adn other metal oxide to make of,comparing with traditional carborundum arrester,it improves greatly V-Acharacteristics of resistance,increases the getting trough ability of resistance,thereby it brings fundamental change to features of arrester.
· Under normal working voltage, the current passing arrseter onlyu A class,when bearing over voltage,the escellentnon-linear V-Afeatures of arrester would make effect,the current passing through the arrester increase high to thoudands of Ampere instant,the arrester is under getting through state,to release over-voltage energy,therefore it effectve limits the admage to power transmission equiqments due to over voltage.
·Applicafion and feafures
· Zno lighting arrester is one kind protecting equipment preventing electric equipments in AC power system from high voctage and over-voltage operation.

Discharging counter
 
·Summary

　　JS8.JS8A discharging counter(hereinafter short for counter) is connected under the arrester in serias used for recoding the operation times of arrester,JSB style is applied for 6kV-220kV arrester,and JS8A is used for valve type arrester with 330kV and/or above,the environment condition shall meet the requirement required by arrester, for example,the altitude doesn’t,exceed4000m,the enxironment temperature is -40℃~+40℃, This counter can’t,be put in theplace that includes gas eroding metal and insulation parts,seri-ous pollution and drasticvibration.
·Structure and property
　　Discharging counter is made up of valve element,silicon bridge type rectifier,capacitor,electromagnetic counter and so on, it mak-es use of the arrester energy(surge current and power frequency current)to fetch the voltage on valve element(non linear resistan-ce),then it charges to the capacitor in single direction through silicon bridge typerectifier,makes the coils of electromagnetic coun-ter discharge with form of DC power tomove the counter,thus it can realixe that the operating tines can be recorded.
·Summary

　　JCQ-C1 type monitor of arrester is connected under arrester in series,it is applied for Zno arrester with 500kV and/or below,used to monitor leakage current and record operation times of arrester,the environment condition shall meet the requirement by arrester,the feature of monitor is antivibration, electromagnetic counting,indicating by current pointer.

　　Discharging counter is made up of valve element,silicon bridge type rectifier,capacitor,electromagnetic counter and so on, it mak-es use of the arrester energy(surge current and power frequency current)to fetch the voltage on valve element(non linear resistan-ce),then it charges to the capacitor in single direction through silicon bridge typerectifier,makes the coils of electromagnetic coun-ter discharge with form of DC power tomove the counter,thus it can realize that the operating tines can be recorded.
Arrester disconnector
 
·Arrester disconnector

　　Arrester disconnector is a device for disconnecting an arresteor from the system in the event of arrester failure,to prevent a persistentfault on the system and to give visible indication of the failed arrester,TL-1 is a thermal explode disconnector, our products as per IEC60099-4.standard.
