The invention discloses an on-pole high-voltage integrated information collector of a 10kV metering device. The metering device is 0.5S in precision grade, adopts a reactive 2 grade, and is 3X10KV inrated voltage, and 50A--600A in rated current; and a three-phase three-line metering system is adopted. The metering device comprises two insulating supporting columns which are vertically arranged; and L1, L2, C1 and C2 are arranged between the two insulating supporting columns; a current signal and a voltage signal are collected in real time, and the electric quantity value calculated by a metering chip is stored in a storage unit, and is wirelessly transmitted to a standard national network centralized collector, and then is uploaded to a master station through a concentrator via a GPRS. According to the invention, the traditional voltage sampling, current sampling and electric energy metering are all integrated in the sensing part at the high-voltage side to realize integrated metering; the magnetic saturation phenomenon does not exist, and the metering device is small in size, light in weight, easy to mount and low in cost.
Description
technical field [0001] The invention relates to a metering device, in particular to a 10kV pole-mounted high-voltage integrated metering device. Background technique [0002] Traditional 10kV outdoor metering device, including high voltage part and low voltage part.
