The Research In Influence Of The Electromagnetic Radiation By High-voltage Transmission And Transformer Of Wuhan City To Urban Environment

As the developing of electrical industry, more and more transmission lines and stations are built to meet the need of power system. In recent years, transmission lines' rebuilding is carried out in many cities and lead to electromagnetic radiation by high voltage transmission lines and stations. Electromagnetic pollution has become a serious problem. Therefore, systematic study on environmental influence by electromagnetic radiation has both important academic meaning and engineering value.Therefore, this paper based on the domestic and foreign existing work's, by conducting the related research to the Wuhan typical region --the East Lake developing zone of the new-high technology in Wuhan city, and it has carried on the comparison the observed value and the theory predicted value, and compares with the corresponding national standards, then makes the analysis, proves the influence of high-voltage power transmission and transformer's electromagnetic radiation to the urban environment of Wuhan typical region, then puts forward the proposal for the urban planning and the high voltage transmission lines. The conclusions in this paper are as follows:(1) Proving the significance and feasibility of this paper, and reviewing the influence and development of the domestic and foreign electromagnetic radiation. The paper has the great significance to the research of electromagnetic radiation pollution, the urban planning and the high voltage transmission lines in Wuhan city, according to the present domestic and foreign research foundation, this paper is feasibly.(2) Analyzing the principle of electromagnetic radiation produced by high-voltage power transmission and transformer as well as the major technique target, and analyzing the method of frequency electromagnetic. Because the terrain is similar in Wuhan city, the paper chooses the most representative region to carry on the survey. Explaining the metering equipment, the measuring technique, the survey environment, the domestic and foreign general judgments standard and the domestic working standard.(3) looking the electromagnetic data of high-voltage power transmission and transformer, it satisfies the electromagnetic radiation environment request; From the rule, we can conclude that the field intensity along with is far away from the transformer substation the distance to increase assumes the declining trend, along with is far away from the high-pressured air line the distance to increase assumes the declining trend.(4) Spotting monitors show that when the electrical equipments are in normal operation, it doesn't do harm to the publics, except in several measuring spots, but no people live there.(5) Proposing the corresponding protective measures by analyzing the present polluting of electromagnetic radiation, and putting forward the reasonable proposal to the plan of urban construction and the reconstruction of the high voltage transmission lines.
