Power frequency electric field and power frequency magnetic field are generated in the surrounding environment near the transmission line or power facilities. The protection of power frequency electromagnetic field is mainly divided into two aspects: one is the protection of personnel exposed to electromagnetic field radiation, and the other is the protection of the places and facilities where personnel are located. At present, the protective materials used in substations are usually metal plates, such as steel plates, copper plates, etc., or protective films or protective materials are added to the plates.

[0003] In the prior art, when performing performance tests on protective materials, the protective effect of the protective materials on the industrial frequency electromagnetic field in the surrounding space is generally measured, and then some test data is obtained. The protective materials are generally made into a box shape, and the test equipment is placed inside for testing. However, the protective materials in the prior art are very inconvenient to install. Sometimes it is necessary to replace protective material boxes of different sizes, and disassembly and assembly are time-consuming, which affects the efficiency of performance testing. In addition, when conducting ambient magnetic field tests, it is not convenient to flexibly adjust the test height of the protective material box. Based on this, improvements are needed.
