Abstract

The invention discloses a noise and electromagnetic radiation monitoring and shielding apparatus for an electrical control cabinet in a communication base station. The apparatus comprises a control cabinet and a housing. The housing is of a structure with three layers, which sequentially include a stainless steel plate, a foamed aluminium plate and a sharp wedged absorbing material plate. A temperature and humidity monitoring module is disposed on the internal surface of the housing. A noise monitoring module and an electromagnetic radiation monitoring module are disposed on the external surface of the housing. A temperature control module is placed inside the housing. The sharp wedged absorbing material plate is adopted for shielding radiation, and has a far better radiation absorption effect that a radiation shielding coating adopted by the prior art. The foamed aluminium plate is adopted for absorption, can further minimize radiation, and can eliminate noise generated by running of equipment as much as possible. The temperature and humidity in the control cabinet can be monitored and an adjusting module for temperature and humidity is adopted, so inconvenience of heat radiation is avoided because the housing is thick, the safety of equipment running is improved, and the service life of equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of electronic communication equipment, in particular to a noise and electromagnetic radiation monitoring and shielding device for an electrical control cabinet of a communication base station. Background technique [0002] The electrical control cabinet is responsible for receiving and controlling the electrical information of each device in the communication base station, but most of the electrical control cabinets are collectively placed in the control room, and the noise and electromagnetic radiation are very large. With the development of my country's electric power industry and the improvement of people's environmental awareness , How to reduce or even eliminate the noise pollution and electromagnetic pollution of electrical control cabinets has become a new topic. At present, the control of noise and electromagnetic radiation in electrical control cabinets mainly relies on the addition of shielding devi...
