Problems solved by technology

[0005] At present, when electric energy meter manufacturers and electric energy meter testing centers conduct electrical fast transient burst immunity performance tests on electronic energy meters in accordance with the requirements of GB17215, GB / T17883, and GB / T18460.3, due to the need to test the The error of the test meter is measured and the meter calibration device of the electric energy meter must be used. The above-mentioned types of interference signals will also interfere with the meter calibration device and cause the test to be unable to proceed smoothly. This problem largely plagues the normal conduct of the test.

Embodiment

[0022] Such as figure 1 As shown, the figure is a schematic diagram of the system structure of the present invention.

[0023] In order to ensure the correctness of the automated detection results and the rationality of the detection logic to the greatest extent, it is necessary to strictly follow the framework results and detection process of the manual test during design, while taking into account different test requirements and the requirements for convenient expansion. The design of automated detection technology The three principles of consistency, comprehensiveness and operability should be followed.

[0024] (1) Consistency principle

[0025] The principle of consistency means that the automated test of the acquisition terminal should be close to the manual test method, and can effectively carry out all the test items and test requirements of the manual test. The results were consistent.

[0026] (2) The principle of comprehensiveness

Abstract

The invention relates to an electric energy meter electromagnetic compatibility immunity automatic test system. The electric energy meter electromagnetic compatibility immunity automatic test system is used for automatically testing the electromagnetic compatibility immunity performance of an electric energy meter. The system comprises an upper computer, a test host, an electromagnetic compatibility immunity generation test device and a meter calibration device, wherein the test host communicates with the host computer, the electromagnetic compatibility immunity generation test device and the meter calibration device. Compared with the prior art, the electric energy meter electromagnetic compatibility immunity automatic test system of the invention has the advantages of high test precision, wide test range and the like.

Description

technical field [0001] The invention relates to the field of electromagnetic compatibility immunity testing of electric energy meters, in particular to an automatic testing system for electromagnetic compatibility immunity of electric energy meters. Background technique [0002] The earliest industry in my country to develop electromagnetic compatibility performance testing is the smart meter industry. This project has also been valued and vigorously promoted by the State Grid Corporation of China. Electromagnetic compatibility testing is a marginal subject and an applied science. The best test results can be obtained only by the integration of test technology and specific test product characteristics, which is particularly prominent in the field of electromagnetic compatibility testing of smart meters. Because many manufacturers engaged in EMC testing technology research and testing equipment manufacturers tend to pay more attention to EMC testing itself, and are not familia...
