Null line break-off metering method for electric energy meter

Abstract

The invention discloses a null line break-off metering method for an electric energy meter. The method comprises the following steps of step 1, setting a punishment mode and a null line break-off metering mode through a main control chip of the electric energy meter; step 2, judging whether the electric energy meter turns on a null line break-off metering mode switch or not, if yes, turning to thestep 3, and if not, ending; step 3, detecting whether a user has a malicious null line break-off electricity stealing event or not, if yes, recording a null line break-off event, and turning to step4, and if not, turning to step 5; step 4, enabling the main control chip of the electric energy meter to start the punishment mode and generate a punishment record, and turning to the step 2; step 5,judging whether a metering chip of the electric energy meter adopts the punishment mode or not, if yes, turning to step 6, and if not, turning to step 7; step 6, enabling the metering chip of the electric energy meter to exit the punishment mode and record a null line break-off end event, and turning to step 2; and step 7, enabling the electric energy meter to meter according to a normal meteringmode, and turning to step 2. According to the method, the electricity stealing event is recorded and punishment is carried out, the traceability is strong, and the loss is reduced.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a method for measuring a broken zero line of an electric energy meter. Background technique [0002] With the improvement of meter technology, power bureaus and users have higher and higher requirements for meter quality and reliability. At the same time, more and more people are trying their best to steal electricity, so as to achieve the goal of paying less for individuals. The power bureau is facing great losses. [0003] At present, most electric energy meters adopt the combination of manganese copper and CT for sampling and measurement. If the user intentionally disconnects the neutral line of the meter and grounds the meter indoors, the meter will power off and stop measuring, and the user can still use it normally. Achieving the purpose of undercounting electricity meters will greatly affect the charging of the power bureau and be unfair to normal users; in addition, the main...

Problems solved by technology

However, this method can only detect the electricity stealing behavior of the broken zero line, but cannot record the electricity theft behavior of the broken zero line, and cannot recover the loss that occurred when the zero line was broken.
