The Investigation On EMF Measurement Method And Limits Of Induction Cooker

With the development of society and science technology, most people share the modern convenience, at the same time they may intend or not to bare the electromagnetic radiation. As we know, so electromagnetic radiation of the induction cooker is an important problem especially to public, the relationship between our daily lives. This article analyze measurement distance of electromagnetic radiation, the frequency distribution characteristics, experiment cooker according to the actual using environment and public custom of induction cooker, and using for reference standards which IEC drew up. As a result, this article has reach conclusion on measurement methods and limits of induction cooker electromagnetic radiation. These achievements provide effective support for electromagnetic radiation measurement.This article combined theoretical analysis with experimental measurement methods to study. Basing on mathematical model, some theoretical calculations and detailed analysis about various factors which effect electromagnetic radiation measurement are made.There are some achievements through above research:Firstly, through measuring the field strength of induction cooker at different locations, studying its electromagnetic distribution, determining its measurement distance and direction, making these measurements more meet the actual using environment and public custom of our country.Secondly, through measuring the field strength generated by different sizes and materials of induction cooker, determining pot of household induction cooker, ensuring different laboratories consistency and retrospective.Thirdly, through analyzing time and frequency and studying field strength of the major frequency point, determining measurement frequency range of household induction cooker electromagnetic radiation, making the range choices of different measuring equipment guidable.Fourthly, based on the establishment of electromagnetic measurement method for induction cooker, and the uncertainty evaluation about measurement results derived from measurement system, ensuring limits are accord with determination science.Through the establishment of household induction cooker electromagnetic radiation measurement methods in this article, the measurement results can help to promote research and development, evaluation, practical application, green technology of induction cooker. Meanwhile induction cooker electromagnetic radiation measurement and evaluation may bring constructive help to overall industrial development of domestic induction cooker.
