The Development of Detection System for Three-Dimensional Alternating Electromagnetic Radiation

Abstract:

Medium frequency induction heating is a kind of energy-saving heating method. Now it has been applied to industrial heating craft, and it reveals that it has wide application prospect. However, due to the problem of electromagnetic radiation, it is extremely necessary to do some detection and protection. Based on this study background and according to the standards of EN62233:2008 Measurement Methods for Electromagnetic Fields of Household Appliances and Similar Apparatus with Regard to the Human Exposure in European Union, the guidelines of ICNIRP (the abbreviation of International Commission for Non-Ionizing Radiation Protection) with the international authority are adopted on the protection standards of electromagnetic field. And a new detection system for three-dimensional alternating electromagnetic radiation has been developed, and is used to detect electromagnetic radiation generated in industrial medium frequency induction heating. In the laboratory test, the precise instrument imported in Germany was a comparison of the equipment. And when testing the same heating object, the test results had better consistency between the precise instrument and the new detection system. On the basis of test requirements in EN62233, a comprehensive value of electromagnetic field intensity has been gotten after the superposition of every effective harmonic component in electromagnetic field, and the prompt of exceed standard is given in the paper, which gives a viable reference and guidance for electromagnetic radiation detection of medium frequency induction heating. After experimental debugging and system calibration in the laboratory, the detection system is running stably and accurately, and reaches the design requirements.
