Embodiment

[0035] An electromagnetic compatibility testing method for online power monitoring equipment, comprising the following steps:

[0036] 1) Communicate and connect the tested sample with the EMC tester, and judge whether the connection is successful, if yes, execute step 2), otherwise continue to execute step 1);

[0037] 2) The electromagnetic compatibility tester conducts electromagnetic compatibility tests on the tested samples, encrypts the test data and uploads them to the host computer through the wireless transmission network;

[0038] 3) After the host computer decrypts the received test data, it matches and compares with the data in the database to obtain the test results of the tested samples.

[0039] The electromagnetic compatibility test items and strengths mentioned are as follows:

[0040] Electrostatic discharge immunity: test level 4, voltage ±8kV-±15kV;

[0041] Radio frequency electromagnetic field radiation immunity: test level 3, electric field strength 10...

Abstract

The invention relates to an electromagnetic compatibility test method and device for electric power online monitoring equipment. The method comprises the following steps of: (1) performing communication connection on a tested sample and an electromagnetic compatibility tester, and judging whether the connection is successful, if the connection is successful, executing the step (2), or otherwise, continuing executing the step (1); (2) testing the electromagnetic compatibility of the tested sample through the electromagnetic compatibility tester, encrypting tested data and transmitting the tested data to an upper computer through a wireless transmission network; and (3) decrypting the tested data received by the upper computer, and matching and comparing the test data with the data in a database to obtain a rest result of the tested sample, wherein the device comprises the electromagnetic compatibility tester, the upper computer, an insulation support, a grounding reference plane and a non-metal pedestal. Compared with the prior art, the electromagnetic compatibility test method and device have the advantages of wide test range, capability of remote monitoring, high test precision and the like.

Description

technical field [0001] The invention relates to an electromagnetic compatibility testing technology, in particular to an electromagnetic compatibility testing method and device used for electric power on-line monitoring equipment. Background technique [0002] The online monitoring function is a basic feature of the intelligence of primary equipment. In order to ensure the function and operation reliability of the online monitoring device, the online monitoring device should undergo performance inspection and acceptance work before it is put into operation. One of the most important tests is the electromagnetic compatibility test. , the electromagnetic compatibility (EMC) test is mainly divided into electromagnetic emission test (EMI) and electromagnetic immunity test (EMS). However, the existing EMC tests generally have the following problems: [0003] 1. The test range is narrow, and only a few types of interference are tested, so that the product cannot be reliably teste...
