Problems solved by technology

[0002] Due to the long-term operation of the power supply system, the electric energy meter (referred to as the electric meter) often breaks down. If the faulty electric meter is not found in time, it is easy to cause problems such as high line loss in the comprehensive station area, and there are also potential safety hazards
Since the electric meter is installed in thousands of households, it is impossible to use large-scale equipment for detection, and the electric meter can only be disassembled for detection; in such an environment, since there is no convenient and practical faulty electric meter testing method and device, it is very difficult to find the faulty electric meter in time. Large volume, long power outage

Embodiment 1

[0021] Embodiment one, with reference to the attached figure 2 .

[0022] Adjust the electric energy meter to the current reading state, set the same time through the timer, observe the current value with the clamp ammeter with the right hand, adjust the electric meter to the current reading with the left hand, and observe the current value observed by the clamp ammeter and the current reading value of the electric energy meter respectively; At the same time, the observed current value of the clamp ammeter is 2.40A, and the current reading value of the electric energy meter is 0.252A. The error of the two current values ​​is above 0.5A, and it is determined that the electric energy meter is faulty.

[0023] The electric energy meter was removed, brought back to the station, and tested with special equipment, and the electric energy meter was damaged.

Embodiment 2

[0024] Embodiment two, with reference to attached image 3 .

[0025] Adjust the electric energy meter to the current reading state, set the same time through the timer, observe the current value with the clamp ammeter with the right hand, adjust the electric meter to the current reading with the left hand, and observe the current value observed by the clamp ammeter and the current reading value of the electric energy meter respectively; At the same time, the observed current value of the clamp ammeter is 1.738A, and the current reading value of the electric energy meter is 1.760A. The error between the two current values ​​is less than 0.5A, and it is determined that the electric energy meter is not faulty.

[0026] Remove the electric energy meter, take it back to the station, and test it with special equipment. The electric energy meter is normal.

Embodiment 3

[0027] Embodiment three, with reference to attached Figure 4 .

[0028] Adjust the electric energy meter to the current reading state, set the same time through the timer, observe the current value with the clamp ammeter with the right hand, adjust the electric meter to the current reading with the left hand, and observe the current value observed by the clamp ammeter and the current reading value of the electric energy meter respectively; At the same time, the observed current value of the clamp ammeter is 0.029A, and the current reading value of the electric energy meter is 0.032A. The error between the two current values ​​is less than 0.5A, and it is determined that the electric energy meter is not faulty.

[0029] Remove the electric energy meter, take it back to the station, and test it with special equipment. The electric energy meter is normal.

Abstract

The invention relates to a device and method for rapidly seeking a fault electric energy meter, and belongs to the technical field of power supply maintenance. According to the technical scheme, callipers of a clip-on ammeter clamp a line loading the live wire outlet end (2); an electric energy meter is adjusted to be in a current reading state, the same time is set through a timer, and then an observation current value of the clip-on ammeter and a current reading value of the electric energy meter are observed separately; if the error of the current values of the clip-on ammeter and the electric energy meter within the same time is 0.5 A or above, it is determined that the electric energy meter is out of order. According to the device and method for rapidly seeking the fault electric energy meter, the fault electric energy meter can be sought visually and rapidly, and the work efficiency is improved; the method is easy to operate, the accuracy can be guaranteed, and a wiring error caused by assembly and disassembly of the electric energy meter is greatly avoided; the power off time is shortened, misunderstanding of users is reduced, and the workload of workers is relieved; in the background art, one hour is needed to disassemble and assemble an electric energy meter for detection, whether the electric energy meter is out of order or not can be judged within one minute at present, and the work efficiency is greatly improved.
