Counter durable 6kv 220kv above 330kv discharge counter

Short Description:

Summary

HW8,HW8A discharging counter(hereinafter short for counter)is connected under the arrester in serias used for recoding the operation times of arrester,JSBstyle is applied for
6kV-220kV arrester,and HW8Ais used for valve type arrester with330kV and/or above,theenvironment condition shall meet the requirement required by arrester,for example,the altitude doesn’t,yexceed4000m,the environment temperature is- 40C~ +40C,This eounter can, tbe put in the place that includes gas eroding metal and insulation parts,seri-ous pollrtion and drasticvibration

HW8-CQ type monitor of arrester is connected under arrester in series, it is applied for Zno arrester with 500kV and/or below, used to monitorleakage curent andrecord operationtimes ofarrester, the environment condition shall meet the requirement required by arrester, the feature of monitor is anti-vibration, electromagnetic counting, indicating by current pointer.

Structure and property

Discharging counter is made up of valve element, silicon bridge type rectifier, capacitor, electromagnetic counter andsoon, 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 sllicon 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.
