　　DJs Baidu series high sensitive arrester discharge recorder function introduction DJs series high sensitive arrester discharge recorder (hereinafter referred to as DJs) is an electronic arrester discharge counter for indoor use (optional arrester leakage current on-line monitoring). It is suitable for discharge counting of arresters without (with Series) gap below 35KV. It can record a, B and C. the number of discharge bs and corresponding discharge time of lightning arrester, liquid crystal display, data recording volume of more than 1000 times, strong anti-interference ability and high sensitivity, and provide network communication and data download interface. Product features: three-phase centralized counting, strip recording of discharge time, communicable, electronic liquid crystal display. Working principle and product comb DJs series high sensitive lightning arrester discharge recorder is mainly composed of sampler, sensor, adapter box, display, supporting transmission cable and some electronic components. Under normal operating voltage, the change of leakage current through lightning arrester is transmitted to the display through sampler and relevant cables, and converted into digital signal and displayed under the control of microprocessor in the display through amplification circuit and a / D conversion circuit in the display. When the lightning arrester flows through lightning wave, operation wave or power frequency overvoltage, the strong b current will be transferred from the leakage current measurement circuit to the counter circuit, and the leakage current measurement circuit is protected. The counter part uses the principle of electromagnetic induction to obtain the signal of operation wave or power frequency overvoltage current, and then processed by the microprocessor in the display to record the number of bs
