Abstract
The utility model relates to a simple test device for broken-down electric energy meters and belongs to the technical field of power supply overhaul and maintenance. According to the technical scheme of the utility model, the device comprises an electric energy meter (5), a detection lamp holder (6), a clip-on ammeter (7), and a timer. From left to right, the electric energy meter is provided with four terminals: namely a live wire incoming terminal (1), a load live wire outgoing terminal (2), a zero wire incoming terminal (3) and a load zero wire outgoing terminal (4). The detection lamp holder and the clip-on ammeter are connected in series and then are connected between the load live wire outgoing terminal and the load zero wire outgoing terminal. The timer is matched with the clip-on ammeter. If the pulse counting error per minute is detected to be more than once, the electric energy meter is judged to be broken down. According to the technical scheme of the utility model, by means of the device, broken-down electric energy meters can be intuitively and quickly found out, and the working efficiency is improved. Meanwhile, the operation is simple and easy to master. The test accuracy is also ensured. Meanwhile, the occurrence of wiring errors due to the disassembly/assembly of electric energy meters can be greatly avoided. The power-failure time is shortened and the misunderstanding of users is relieved. The workload of workers is also lightened.
Description
Technical field
The utility model relates to a kind of fault electric energy meter Simplified Test Equipment, belongs to electric power repair maintenance technology field.
Background technology
Electric power system is due to long-time running, and ammeter often breaks down, and is untimely if the fault ammeter is found, is easy to cause the problems such as all-in one desk district line loss height, also has potential safety hazard.Because ammeter is arranged on huge numbers of families, can not use large-scale the detection, can only detect by the dismounting ammeter; Under such environment, owing to there is no easy fault ammeter method of testing and device, find that in time the fault ammeter is very difficult, workload is large, and power off time is long.
The utility model content
The utility model purpose is to provide a kind of fault electric energy meter Simplified Test Equipment, the convenient use, and the band electro-detection can detect the fault ammeter very soon, in time finds the fault ammeter, solves the problems referred to above that background technology exists.
The technical solution of the utility model is:
Fault electric energy meter Simplified Test Equipment comprises electric energy meter, detects lamp holder, clamp on amperemeter, timer, from left to right, is provided with four terminals on electric energy meter, is respectively live wire end of incoming cables, load live wire leading-out terminal, zero line end of incoming cables and load zero line leading-out terminal; After detecting the series connection of lamp holder and clamp on amperemeter, be connected between load live wire leading-out terminal and load zero line leading-out terminal; Timer coupling clamp on amperemeter.
Described detection lamp holder is the 100W bulb.The band electro-detection is simulated load below electric energy meter with the detection lamp holder, from left to right, is provided with four terminals on electric energy meter, is respectively live wire end of incoming cables, load live wire leading-out terminal, zero line end of incoming cables and load zero line leading-out terminal; After detecting the series connection of lamp holder and clamp on amperemeter, be connected between load live wire leading-out terminal and load zero line leading-out terminal; The per minute pulse number of normal electric energy meter equals: meter constant * 0.1 ÷ 60, the right hand is observed current value with clamp on amperemeter, left hand is taken timer observation ammeter ruuning situation, if the umber of pulse error that per minute is measured more than once, just judges that this electric energy meter has fault.
Good effect of the present utility model: can find bug list intuitively, fast, increase work efficiency; And the method is simple to operate, easily grasps, and can guarantee accuracy, has greatly avoided causing wiring error because of dismounting ammeter reason; Shorten power off time, reduced user's the workload that has not understood, alleviated the staff; The work that needed in the past complete in one hour only needs ten minutes now, has greatly improved work efficiency.
