Problems solved by technology

It is only to verify the metering wiring method and the constant of the meter (that is, between the number of revolutions or the number of pulses and the load). It is impossible to change the constant of the meter (the number of revolutions of the turntable or the pulse number and pulse strobe of the electronic meter) and only change the counting degree. On-site verification by means of electricity stealing with less electricity metering
At the same time, what is more important is that the on-site magnetic field has a large interference factor to the inspection equipment, and it is even more difficult to detect users who steal electricity

Abstract

The invention discloses a watt-hour meter metering abnormality in-situ automatic diagnosis and treatment device comprising a clip-on current transformer, a standard watt-hour meter connected with the clip-on current transformer, and a programmable controller connected with the standard watt-hour meter. An adsorption mechanism is arranged on one side of the standard watt-hour meter. The outer surface of the clip-on current transformer is coated with an insulating layer. The device only compares the number of counted degrees of a field watt-hour meter and the standard number of degrees measured by the tool, and is accurate in judgment and quick.

Description

technical field [0001] The invention relates to the technical field of electric energy meter detection in electric power systems, in particular to an on-site automatic diagnosis and processing device for abnormal measurement of electric energy meters. Background technique [0002] With the popularization and application of electric energy meters, the current electricity stealing methods of electricity thieves are also gradually upgraded. There are endless electricity stealing methods for electronic meters. Go slow, this method of stealing electricity is relatively high-tech and powerful, it does not change the constant of the meter (the number of revolutions of the turntable or the number of pulses of the electronic meter and the pulse strobe), but only changes the counting degree and reduces the amount of electricity; the consequences are very serious. It is not easy to verify. The principle of causing less metering is: the electricity-stealing molecule installs a digital ...
