Abstract

The invention discloses an outdoor three-phase high-voltage electric energy meter, which comprises an electric energy meter device and an electricity larceny prevention monitoring device. The electricenergy meter device comprises a high-voltage module, a low-voltage module and a micropower wireless communication module. The high-voltage module is used for realizing sampling and metering of electric energy data, and comprises an AB-phase voltage sensor, a CB-phase voltage sensor, an A-phase current transformer, a C-phase current transformer and an electric energy metering unit, and the low-voltage module comprises a low-voltage control terminal for realizing on-site display and remote transmission of electric energy data; the electric energy metering unit is connected to the low-voltage control terminal through the micropower wireless communication module; the electricity larceny prevention monitoring device comprises an electricity larceny prevention wiring terminal and an electricitylarceny prevention detection module, the electricity larceny prevention wiring terminal is connected to a load power utilization circuit of the electric energy metering unit in series, and the electricity larceny prevention detection module is used for monitoring the electricity larceny phenomenon and sending out an electricity larceny alarm signal when the electricity larceny phenomenon exists.The outdoor three-phase high-voltage electric energy meter is high in integration degree, convenient to use, small, exquisite, high in safety, excellent in electricity larceny prevention performance and capable of achieving electricity larceny real-time alarming.

Description

technical field [0001] The invention relates to the technical field of high-voltage electric energy meters, in particular to an outdoor three-phase high-voltage electric energy meter. Background technique [0002] The traditional outdoor high-voltage metering device consists of three parts: high-voltage PT, high-voltage CT and low-voltage electric energy meter. The ferromagnetic transformer is heavy, and there is a certain hidden danger of ferromagnetic resonance. Its copper loss and iron loss also cause a waste of energy; the secondary wiring is cumbersome and prone to errors; the secondary wire and the meter pole on the low-voltage side prone to electricity theft. Contents of the invention [0003] The present invention aims to at least solve the technical problems existing in the prior art, and especially innovatively proposes an outdoor three-phase high-voltage electric energy meter, which has a high degree of integration, is convenient and compact, has high safety, a...
