JCQ-10 Discharging counter
1.Summary
JQC-C1 type monitor of arrester is connected under arrester in serial,it is applied for Zno arrester with 50kv and/or below,used to monitor leakage current and record operation times of arrester,the environment condition shall meet the require ement required by arrester by arrester,the feature of monitor is anti-vibration,electromagneic counting,indicating by current pointer.
2.Structure and characteristic
Discharging counter is made up of valve element,silicon bridge type rectifier,capacitor,electromagnetic counter and so on,i makes use of the arrester energy(surge current and power frequency current) to fetch the voltage on valve element(nonlinear resistance),then it charges to the capacitor in single direction through silicon bridge type rectifier,makes the coils of electromagnetic counter discharge with form of DC power to move the counter,thus,it can realize that the operating times can be recorded.
