The disadvantages of the existing scheme are: in the work of meter installation and power connection, some technical problems that are not easy to solve on site are often encountered. 1. The secondary line of on-site measurement does not meet the standard requirements. 2. The secondary measurement in the power distribution cabinet is cumbersome and messy, and it is necessary to use a multimeter to check one by one, which is time-consuming. 3. Some of the metering secondary lines in the power distribution cabinet will be connected in series with the ammeter, which will bring hidden dangers to metering safety. 4. Sometimes the secondary metering line in the power distribution cabinet is relatively short. Although it can be connected, the line is not neat and not beautiful. The purpose of the present invention is to solve the problem of safe, beautiful, fast and accurate connection of the secondary circuit of metering at the work site, improve work efficiency, eliminate wrong wiring, and improve economic benefits.
