Twelve epitopes are used to place the detected power quality monitoring device 3 . The detection controller 1 can be placed on the top right of the detection table 7 .

Specifically, the test frame 6 can be integrally formed with the test table 7, or can be separated.

The power quality monitoring device detection platform disclosed in the present application is provided with a test frame 6 on the detection table 7. The test frame is divided into three-layer structures, and the device to be tested and the detection instrument are respectively stored, which facilitates the centralized management of the equipment. The detection controller 1 can be placed on the right side of the detection table 7, so that most of the lines that need to be connected during detection can be pre-connected, as long as the device to be tested is connected to the line, the wiring workload is reduced.

Referring to FIG. 1 , we can also set an integrated junction box 61 behind and above the twelve epitopes of the test rack 6 , and each junction box 61 is equipped with a network cable, power supply, voltage and current interfaces. It is used to connect the device under test into the circuit through wires.

Of course, for the convenience of users to watch and use, we can also set a label on each interface to indicate the name of each socket.
