Abstract

The invention discloses a noise and electromagnetic radiation monitoring and shielding system for an electrical control cabinet of a substation, comprising a control cabinet, a noise monitoring module and an electromagnetic radiation monitoring module uniformly arranged in a control room, a data transmission unit, a control center unit and a terminal display unit. The control cabinet includes a cabinet body and a sealed door, a cavity is arranged inside the sealed door, threaded holes communicating with the cavity are evenly distributed on the inner surface of the sealed door, and an air injection mechanism or a hole cover is arranged on the threaded hole, The cavity is connected with an air supply mechanism, an exhaust mechanism is arranged above the cabinet, and a temperature monitoring module and a smoke monitoring module are arranged in the cabinet. The invention uses a sealed control cabinet to shield the internal electromagnetic radiation and noise, and combines the map in the control room with the monitored noise and radiation conditions to remind on-site personnel, bypass areas with high radiation intensity, and timely Remind maintenance, reduce the damage caused by electromagnetic radiation and noise to the on-site staff.

Description

technical field [0001] The invention relates to the technical field of electromagnetic fields, in particular to a noise and electromagnetic radiation monitoring and shielding system for an electrical control cabinet of a substation. Background technique [0002] The electrical control cabinet is responsible for receiving and controlling the electrical information of each device in the substation, 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 awareness of environmental protection, 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 devices. The shielding device is g...
