Fault electric energy meter rapid judgment method by applying multi-epitope electric energy meter detection device

Abstract

The invention discloses a fault electric energy meter rapid judgment method by applying a multi-epitope electric energy meter detection device, belonging to a method for measuring an electric energy meter fault. An electric energy meter is connected with the multi-epitope electric energy meter detection device, a communication state between epitopes in the electric energy meter detection device is detected according to segments so as to rapidly find the position at which a fault electric energy meter is located. By the method, the fault electric energy meter in the electric energy meter connected with the multi-epitope electric energy meter detection device can be judged within 1 minute, fault judgment time is reduced, and verification efficiency is improved; each fault finding time of the traditional finding method is about 2.5 minutes, each fault finding time of the method is about 1 minute, and verification efficiency is greatly improved.

Description

technical field [0001] The invention relates to a measuring method for measuring the fault of an electric energy meter, in particular to a method for quickly judging a fault electric energy meter by using a multi-meter position electric energy meter detection device. Background technique [0002] With the increasing amount of electric energy meter verification, 24-meter, 48-meter or even 96-meter electric energy meter verification devices have become the mainstream configuration. This kind of verification device can carry out the verification of electric energy meters in batches, greatly improving the verification efficiency . However, due to the crimping method used between the watt-hour meter verification device and the ammeter, sometimes a few watt-hour meters have poor contact and cause the current loop to open, which affects the verification work. The electric energy meter verification device itself does not have an automatic fault finding device, and can only use manu...

Problems solved by technology

However, due to the crimping method used between the watt-hour meter verification device and the ammeter, sometimes there will be an open circuit of the current loop due to poor contact of individual watt-hour meters, which will affect the verification work.

The electric energy meter verification device itself does not have an automatic fault finding device, and can only use manual measurement. Due to the large number of meter positions, it takes a long time to check in sequence according to the order of the meter positions

If you upgrade the verification device and install an automatic fault finding device, firstly, the capital investment will be large, and secondly, the verification device itself will need to be damaged to a certain extent, which may cause the overall performance of the device to decline
