A stability test method for automatic verification system of direct-in three-phase smart energy meter

Abstract

The invention relates to a stability test method for an automatic verification system of a direct-in three-phase intelligent electric energy meter. The verification process steps on the automatic assembly line verification system are as follows: (1) Preparation: input the information of the standard electric energy meter into the verification system; (2) Install the meter : Put the standard electric energy meter tray into the binding position and randomly mix the electric energy meter with normal tasks into the automatic verification line; (3) Binding: the assembly line server will compare the barcode number of the standard electric energy meter with the information of the tray according to the preset scheme Binding; ⑷Test: The automatic line will execute according to the predetermined test plan; ⑸The table below: PLC will automatically identify the standard electric energy meter on the tray according to the binding information, and the standard electric energy meter will carry out the process of steps ⑶, ⑷, and ⑸ in a cycle; ⑹Data processing: Export test data. The invention is scientific in design, convenient in operation, accurate and reliable, realizes periodic checking of electric energy metering devices or instruments and equipment, and can effectively ensure accurate and reliable transmission of electric energy values.

Description

technical field [0001] The invention belongs to the field of electrical measurement and instrumentation, in particular to a stability test method for an automatic verification system of a direct-in type three-phase intelligent electric energy meter. Background technique [0002] Electric energy has become an indispensable and important energy source for the survival and development of human society. Almost all human activities are closely related to electricity, and electric energy meters are direct measuring instruments for detecting electric energy usage standards. How to ensure the calibration of electric energy meters The accuracy and efficiency of the test, and efforts to improve the calibration efficiency of the electric energy meter have become problems that need to be solved urgently by the measurement and testing departments at all levels. [0003] In order to maintain the reliability of electric energy metering devices and test equipment, and ensure the accuracy an...

Problems solved by technology

At present, the method of checking during the period is to use the online detection of the electric energy meter to be tested. Dozens to hundreds of detection equipment are installed on the detection line to meet the online detection requirements of a large number of electric energy meters. The detection accuracy of the multiple detection equipment itself is calibrated It has become another difficult problem to ensure the detection accuracy of electric energy meters. Because the existing equipment itself is large in size, heavy in weight and difficult to move, it is necessary to manually carry the calibration equipment to disassemble, connect, and calibrate the testing equipment, often every calibration cycle Long time, heavy manual workload and low work efficiency
