The system is characterized in that: junction boxes are provided and can realize semi-automatic wiring; a built-in test circuit is provided, voltage functions are connected in parallel, current functions are connected in series for testing, a single calibration source can be used for calibrating the three-phase multifunctional electric power parameter measuring instrument, three paths of voltage or three paths of current of a calibrated multifunctional electric power parameter measuring instrument can be measured at the same time, the calibration time is shortened, and the calibration efficiency is improved; a built-in test circuit is provided, and a built-in line program control change-over switch is arranged, so that a wire does not need to be replaced in a test process, the test process is simplified, the verification time can be shortened, the working intensity of personnel is reduced, and the risk in verification is reduced; and a calibration platform is provided with four junction boxes, the junction boxes are simple and convenient to operate and are in good contact with the calibrated multifunctional electric power parameter measuring instruments, at most four multifunctional electric power parameter measuring instruments can be calibrated at the same time, and the calibration efficiency is improved.

Description

technical field [0001] The invention belongs to the field of measurement verification, and in particular relates to a verification system of a multifunctional power parameter measuring instrument. Background technique [0002] The multifunctional power parameter measuring instrument is used to monitor power parameters such as AC phase voltage, line voltage, current, frequency, power factor (phase), etc., and is widely used in online monitoring of power systems and measurement of various electrical parameter indicators. In order to avoid the influence caused by the reduction of the measurement accuracy of the meter during long-term use, it is necessary to carry out periodic verification of the power meter. [0003] At present, manual verification is generally used. The verification process needs to connect the power line of the multi-function power parameter measuring instrument to supply power to it, connect the calibration source and the test line of the multi-function powe...
