The invention discloses an anti-interference grounding method for medium-high frequency equipment. The method comprises an accelerator power supply chamber and a high-frequency tube power source, the high-frequency tube power source is arranged in the accelerator power supply chamber, the accelerator power supply chamber is arranged in a building wall, and a horizontal grounding grid and a vertical grounding electrode are arranged at a position 5 meters away from the outer side of the edge of the outer wall of the building. A copper sheet and the grounding electrode are used as grounding materials so that independent grounding of high-frequency equipment is realized, and high-frequency signals are prevented from interfering with other equipment. When a grounding scheme is adopted, interference phenomena of high-frequency standing waves, grounding loops and the like are avoided, and the grounding system is independent of the combined grounding grid of the building so that other equipment in the building cannot be interfered and influenced.
Description
technical field [0001] The invention belongs to the technical field of grounding systems for medium and high frequency equipment, in particular to a grounding method for preventing interference of medium and high frequency equipment. Background technique [0002] Cyclotrons are widely used in the research fields of heavy ion biological effects, heavy ion cancer treatment, material science and single event effects of aerospace devices, especially in the fields of radiopharmaceuticals and tumor treatment. It is imperative to build a medical cyclotron with independent intellectual property rights and put it into operation smoothly. Hefei Ion Medicine Center has carried out proton therapy and other related biomedical research, and has done a lot of research and experimental work on the development of superconducting cyclotrons. [0003] The frequency of the RF system of the important high-frequency equipment in the cyclotron reaches 92MHz. In order to ensure the stable operatio...
