Problems solved by technology
[0002] The commissioning and general inspection of the existing single-phase electric energy meters are carried out separately, requiring two sets of equipment, and the cost is relatively high; and after the commissioning is completed, all the electric energy meters to be inspected need to be moved to the general inspection station, and then the electric energy meters are inspected. The general inspection can only be carried out after rewiring. Rewiring can prevent the bad meter from being transferred out, because if the wiring of the electric energy meter is not connected properly during debugging, although the electric energy meter can be adjusted to the range where the error limit is, but because the debugging is not normal Under the wiring, the meter may not be adjusted properly, but after the general inspection is rewired, the probability of detecting unqualified meters during the general inspection can be increased, thereby preventing the circulation of such bad meters. However, the above process still takes a lot of time to transport the energy meter from the debugging station to the general inspection station, and the detection efficiency is low

A single-phase watt-hour meter debugging and inspecting integrated device comprises a frame, a principal computer and a programmable power source. The frame is equipped with a standard meter and N meter calibration stations, wherein N is greater than or equal to 2. The device is characterized in that each meter calibration station includes a tray provided with one or more meter positions, ejector pin block components corresponding to the meter positions, and a front-back linear drive mechanism used for driving the ejector pin block components to be connected with or disconnected from calibrated meters in the meter positions; the first to (N-1)th meter calibration stations on the frame are used for debugging, and the second to Nth meter calibration stations are used for general inspection; and the frame is further equipped with a tray conveying channel used for conveying the trays. With the single-phase watt-hour meter debugging and inspecting integrated device, debugging and general inspection can be performed together, and rewiring can be carried out during general inspection to prevent bad meters from flowing out. In addition, the invention provides a single-phase watt-hour meter debugging and inspecting integrated method.
