Problems solved by technology

[0002] Due to the long-term operation of the power supply system, the ammeter often breaks down. If the faulty ammeter 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 a large scale for detection, and the electric meter can only be disassembled for detection; in such an environment, since there is no simple faulty electric meter testing method and device, it is very difficult to find the faulty electric meter in time, and the workload is heavy , long power outage

Embodiment Construction

[0013] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0014] A simple test device for a faulty electric energy meter, including an electric energy meter 5, a detection lamp holder 6, a clamp ammeter 7, and a timer 8. There are four terminals on the electric energy meter from left to right, which are the input terminal 1 of the live wire and the outgoing line of the live wire of the load. Terminal 2, neutral line input terminal 3 and load neutral line output terminal 4; after the detection lamp head and the clamp ammeter are connected in series, connect between the load live line output terminal and the load neutral line output terminal; the timer matches the clamp ammeter.

[0015] The detection lamp holder is a 100W light bulb.

[0016] The simple test method for the faulty electric energy meter is carried out by using the simple test device for the faulty electric energy meter mentioned above. Fo...

Abstract

The invention relates to a simple faulted electric energy meter test method and belongs to the technical field of power supply inspection and maintenance. According to the technical scheme, the detection is carried out in electrification, a detection lamp holder is used to simulate loads under an electric energy meter, the detection lamp holder is serially connected to a pincerlike ampere meter, and is connected between a load firing line leading-out terminal and a load null line leading-out terminal; a timer is matched with the pincerlike ampere meter; the pulse time per minute of the normal electric energy meter is equal to a pulse constant multiplied by 0.1 and divided by 60, the pincerlike ampere meter is held in a right hand to observe a current value, and the timer is held in a left hand to observe the operation condition of the ammeter, if the error of the detected pulse number per minute is more than once, then the electric energy meter is judged to be faulted. The simple faulted electric energy meter test method and device has the advantages that the faulted meter can be found visually and fast, and working efficiency is improved; the method and device is simple in operation, easy to master, and capable of guaranteeing the accuracy and greatly avoiding wiring errors caused by dismantling of the electric energy meter; power failure time is shortened, complaint of users is reduced, and workload of workers is reduced.
