Outdoor high-voltage electrified installation and removal electric energy metering device

Abstract

The invention relates to an outdoor high-voltage electrified installation and removal electric energy metering device which comprises a current transformer, a voltage transformer and an electric energy meter box, wherein the current transformer is mounted on a high-voltage phase line, a high-voltage one-phase line penetrates through the middle hole of an iron core of the current transformer, and an outlet wire of a secondary winding of the current transformer is connected with an electric energy meter; the voltage transformer is mounted in the electric energy meter box or on an electric pole, the two outlet wire ends of a primary winding of the voltage transformer are connected with high-voltage two-phase lines, and the two outlet wire ends of the secondary winding of the voltage transformer are connected with the electric energy meter; and an electric energy meter box body is mounted on the electric pole or a transformer trestle, and the three-phase electric energy meter is mounted in the electric energy meter box. By applying the outdoor high-voltage 10kV electrified installation and removal electric energy metering device, the problem of frequent power failure caused by installation and removal of the electric energy metering device for checking can be avoided, when the electric energy metering device is installed or removed, the operation can be performed in an electrified manner without affecting the power supply for users, and the application of the outdoor high-voltage electrified installation and removal electric energy metering device can be used for improving the reliability in power supply and increasing the enterprise and social benefits.

Description

technical field [0001] The invention relates to an outdoor high-voltage live assembly and disassembly electric energy metering device, which is applied to on-site high-voltage electric energy metering for 10kV distribution network branch lines and distribution transformers. 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 distribution network lines and on-site power metering devices for transformers are all fixed, and assembly and disassembly require power outages. Metering devices, frequent power outages during assembly and disass...

Problems solved by technology

The power of the power grid is transformed and sent to thousands of households through the distribution network and distribution transformers. The current operating distribution network lines and on-site power metering devices for transformers are all fixed, and assembly and disassembly require power outages. Metering devices, frequent power outages during assembly and disassembly, affect user power supply, reduce power supply reliability, and affect power supply enterprises and social benefits
