The invention provides safety performance testing equipment of a high-frequency electromagnet wave and belongs to the field of testing equipment. The safety performance testing equipment of the high-frequency electromagnet wave comprises a high-frequency electromagnet wave emitter, a grinding spark testing device and a motor, wherein an electrode holder and a cadimium plate are arranged in the grinding spark testing device, and tungsten wires are arranged at the lower side of the electrode holder, the high-frequency electromagnet wave emitter is respectively connected with the electrode holder and the cadimium plate and used for providing the high-frequency electromagnet wave for the electrode holder and the cadimium plate, and the motor is respectively connected with the electrode holder and the cadimium plate and used for driving the electrode holder and the cadimium plate to rotate during a test and enabling the tungsten wires at the lower side of the electrode holder to contact with the cadimium plate. During the test, when the tungsten wires at the lower side of the electrode holder contact with the cadimium plate, if the high-frequency electromagnet wave provided by the high-frequency electromagnet wave emitter is high enough, combustible gas in the grinding spark testing device can be detonated, and therefore the extremum range of the high-frequency electromagnet wave of the comestible gas can be confirmed, wherein the content of the comestible gas is known. Therefore, the high-frequency electromagnet wave equipment which can be safely used in a corresponding underground coal mine can be ensured.
Description
technical field [0001] The invention relates to safety performance test equipment, in particular to high-frequency electromagnetic wave safety performance test equipment. Background technique [0002] Driven by the development of science and technology, high-frequency electromagnetic wave equipment such as ground penetrating radar, pit penetrator, wireless communication equipment, electric law instrument and handheld mobile phone are widely used in the coal mining process. They are in the process of ensuring the safety of coal mine production. played an immeasurable role. [0003] However, because there is usually a large amount of combustible gas underground in coal mines, if the combustible gas content is too high, the high-frequency electromagnetic wave equipment is prone to explosion during use. Therefore, in order to ensure the safety of high-frequency electromagnetic wave equipment, it is necessary to measure the extreme value range of high-frequency electromagnetic w...
