Pillar and merging device, the capacitor are concatenated with arrester；
The current transformer in parallel with capacitor is accessed in the high voltage end of the arrester, for transmitting the dynamic of arrester
Make data to the harvester；
The harvester is arranged in the sensing head part on insulation column top, with the action data for being collected in arrester；
The merging device is connected with the insulation column, and the action data of the arrester of collection is transferred to by the insulation column
Merge the processor processing in device and transmit.
Further, the current transformer front end sets and is connected with voltage limiter, and the power frequency at limiting capacitance device two ends is excessively electric
Pressure.
Further, the current transformer is a great current mutual inductor and a small current mutual inductor, the big electricity
