Ac coil/power frequency magnetic field coil
The power frequency magnetic field coil is designed for the power frequency magnetic field anti-interference test and meets the GB/T 17626.8 standard. The power frequency magnetic field coil shall generate a magnetic field strength corresponding to the selected test grade and the specified uniformity. The magnetic field strength shall be up to 2 kA/m. The magnetic field strength can be customized. The power frequency coil designed and manufactured by our company is made of non-metallic non-magnetic materials. Its cross section and mechanical structure are stable, which is conducive to stabilizing the coil during the test. The coil is of suitable size to surround the EUT (in three mutually perpendicular orientations) Customizing power frequency coils of different sizes according to the size of EUT can generate a uniform magnetic field in the whole volume of desktop equipment or vertical equipment with a deviation of+/-±3dB. When testing small equipment such as (computer monitor, watt-hour meter, program-controlled transmitter, etc.), the induction coil of standard size is a square with a side length of 1m or a circle with a diameter of 1m. The volume of test area for standard square coil is 0.6m*0.6 * 0.5m; When it is necessary to test equipment with larger volume, double coils of standard size can be used, and the volume of test area is 0.6m*0.6m*1.0m .. In order to adapt to three perpendicular magnetic field tests, the coil can rotate 90 to 360 degrees and the test bench can rotate 360 degrees. Power frequency magnetic field coils with special requirements can be customized.
