Abstract
The invention relates to the power field, especially relates to the technical field of power equipment, and specifically relates to a 10kV distribution network high-voltage metering device based on an electronic-type sensor. The device comprises a measurement unit, a data processing unit and a communication unit, wherein the measurement unit mainly consists of a signal conditioning circuit, a metering circuit, and a pulse output circuit. The device takes the electronic-type sensor disposed in 10kV distribution network equipment as the signal conversion equipment, and is substantially different from a metering device which takes a conventional electromagnetic mutual inductor as signal conversion equipment. Compared with the prior art, the device can achieve the functions of high-voltage electric energy metering and real-time monitoring at equipment nodes of a 10kV distribution network, such as a segmented node, branch nodes, a column switch and a ring main unit, and provides essential data for the analysis of high-voltage line loss.
