Abstract

The invention provides a single-phase electric energy meter debugging device which comprises a frame, a programmable power source and a host computer. The frame is provided with one or more calibration stations. Each calibration station is provided with one or more meter positions. The device is characterized in that the voltage passage of each meter position is provided with a first relay used for controlling voltage on and off; and the current channels of the respective epitopes are provided with a second relay for controlling the current on and off And a monitoring board is arranged on the frame, the monitoring board is provided with a relay monitoring module which is electrically connected with the first relay and the second relay of each epitope for monitoring the first relay and The second relay is switched on. The single-phase energy meter of the adjustment device for each of the current channel and the voltage channel on the relay switch status real-time monitoring.

Description

technical field [0001] The invention relates to the technical field of a detection device for a single-phase electric energy meter, in particular to an adjustment device for a single-phase electric energy meter. Background technique [0002] In the debugging and general inspection process of the existing single-phase electric energy meter, since multiple test points are required to be detected, after a test point is detected, it is usually necessary to disconnect the relays on the voltage channel and the current channel, and wait for the program-controlled power The voltage and current of the source are adjusted to the new test voltage and test current before reclosing the relay. However, in the actual detection process, some relays may fail to close reliably, so that the voltage and current of the programmable power source cannot be reliably connected to the corresponding meter, thus affecting the detection results of debugging and general inspection. Contents of the inve...
