Low-voltage electric energy metering device capable of being assembled and disassembled in electrified state

Abstract

The invention discloses a low-voltage electric energy metering device capable of being assembled and disassembled in electrified state. The device comprises a current mutual inductor, an electric energy meter box and an insulating wire clamp; the current mutual inductor is mounted on a low-voltage phase wire, the low-voltage phase wire passes through a central hole of a current mutual inductor iron core, a secondary winding outgoing line of the current mutual inductor is connected with the electric energy meter, the current mutual inductor is mounted in the electric energy meter box body or an indoor / outdoor low-voltage phase wire; the electric energy meter is directly clamped on the phase wire by the insulating wire clamp to collect voltage data required by the electric energy meter; the electric energy meter box body is mounted on an electric pole or a transformer rack; a three-phase four-wire electric energy meter is mounted in the electric energy meter box. When assembling and disassembling the electric energy metering device for assessing, the operation can be performed in electrified state without influencing the power supply to the user; the low-voltage electric energy metering device provided by the invention can improve the reliability of power supply and increase the enterprise and social benefit.

Description

technical field [0001] The invention relates to a low-voltage live assembly and disassembly electric energy metering device, which is a low-voltage electric energy metering device applied to low-voltage distribution network branch lines and distribution transformers on site. Background technique [0002] At present, with the rapid development of industrial and agricultural production, the rapid improvement of the national economy, the continuous improvement of people's living standards, the unprecedented development of the power industry, and the rapid development of the national smart grid construction. The power of the power grid is transformed and sent to thousands of households through the distribution network and distribution transformers. The current operating low-voltage distribution network lines and transformer low-voltage on-site energy metering devices are all fixed, and assembly and disassembly require power outages, especially for assessment purposes. The power ...
