Feel the impact on animals is not small, I heard that a homing pigeon farm is not far from the 500 thousand volt substation, often near the wire dead dove, a lot of headless, very scary. Ask an expert, how far is at a distance of substation safe distance I help him answer input content has reached the limit the length of input 9999 words insert picture insert delete pictures map delete map insert video video map can answer 2 points experience value, answer is chosen as a satisfactory answer can be simultaneously increase the value of experience and wealth valueReference: anonymous answer, submit, reply cancel2010-9-17 23:08 wonderful answer general safety distance is charged or wire, according to the relevant provisions of the safe distance of buildings and power lines are as follows; 1, the vertical distance;the power line voltage below 1kV; 2.5 meters; power line voltage level 1- 10kV; 3 meters; power line voltage 35kV:4 meters; power linevoltage meter 60-110kV:5 the power line voltage; 154-220kV:6 meters;power line voltage 330kV:7 meters; 2, the horizontal distance between the power line voltage below 1kV: 1 meters; power line voltage 1-10kV:1.5 meters; power line voltage 35kV:3 meters; power line voltage 60-110kV:4 meters; power line voltage level 154-220kV; 5 meters; power line voltage 300kV; 6 meters; power line voltage meter 500kV:8. The above regulation is the minimum distanceregulation to ensure that no discharge accident occurs. In addition, the safety distance of electromagnetic radiation should be considered, but there is no corresponding regulation about the safety distance of electromagnetic radiation.The national "electromagnetic radiation management measures" provisions of more than 100 thousand volts strongelectromagnetic radiation works, the provisions of article twentieth: in use around the large equipment or high-frequency electromagnetic radiation equipment, according to the environmental protection and the requirements of city planning, in the planning restrictions or construction of residential housing, kindergartens and other sensitive buildings within the area. It is understood that, at present, the state provides more than 100KV power supply facilities, and its construction must be approved by the environmental protection department of the administration. Among them, the environmental protection indexes mainly include four parts: electric field, magneticfield, radio interference and noise.The establishment of the power supply facilities in residential areas, through the environmental protection administrative license, must meet these standards: power frequency electric field strengthless than 4 thousand V / M; magnetic induction strength less than 0.1 milli Tesla;radio interference, the 110KV project which does not exceed 53 dB, 55 dB less than 500KV Engineering; noise for daytime not more than 55 dB, the night does not exceed 45 decibels. As long as these indicators meet the standard, in environmental protection, there is no strict requirement for the distance between the relevant equipment and building.However, according to the environmental protection department, China has a certain distance between equipment and buildings. For example, the general requirements of 10KV-35KV substation, positive from residential above 12 meters, 8 meters above the side; the construction of 35KV substation, it is required from the residential side of 15 meters, 12 meters above the box type substation from residential; 5 meters.The following content is controversial, without legislation, the law does not support:1. according to the electromagnetic radiation produced by UHV powertransmission project to close contact damage problem, Chinese EMC, Professor Committee Gao Yougang China Electrotechnical Institute Professor Zhao Yufeng, Beijing Institute of labor protection of the original director Professor Tao Yongxian pointed out that many experts at home and abroad have much scientific evidence shows that more than 0.2 micro electromagnetic magnetic field Tesla radiation environment may cause harm to the human body, and it has been confirmed by a large number of domestic and foreign scientific evidence.Note: generally, 2000 meters away from the substation, close to the environment, the background value of 0.2 micro Tesla2. British and American countries electromagnetic radiation protection Specialized Committee experts, after years of research, in 1995 proposed the national health standards (100 micro Stella) revised to 0.2 micro Stella.ThreeProfessor Cao Zhaojin of the environment center of China Center for disease prevention and prevention pointed out that the harm caused by electromagnetic radiation to human health is caused by accumulation, and even if it does not exceed the standard, it can not be said thatit is not harmful.4. during the two sessions in 2005, deputies to the National People's Congress and academician Wang Xiaomo of the Chinese Academyof Engineering suggested that laws and regulations on anti electromagnetic pollution should be formulated as soon as possible so as to protect the health of the people". It has been clearly stated that "the existing standards have been unable to meet the new problems", and the relevant laws and regulations should be formulated to protect the environment, safety and health".5. Hunan provincial CPPCC Vice Chairman of the CPPCC National Committee, Professor Cai Zixing and other 16 members of "high voltage transmission lines and substation construction should be away from residential areas" proposal, pointed out that "at present the masses have great views of the case, and that residents should try to negotiate, the consultations did not result, especially the substation engineering, the masses are losing some pressure to the overall situation, power construction departments should also take a step away from residential areas".6., Beijing Planning Commission (2004 regulation word 0638) for approval of the Olympic Information Center building around 220 thousand volts underground high voltage substation project,specifically requested distance of not less than 2000 meters.7. many domestic and foreign professional institutions and experts through dozens of years of investigation have confirmed: "theprobability of 220kV high voltage line 2000 meters around the area of the people suffering from leukemia, cancer is several times more than in other regions, the electromagnetic radiation can also cause miscarriage, fetal abnormalities and cardiovascular disease. In the high temperature, wind, snow, rain, lightning and other meteorological conditions, prone to fracture and other hazards occurred."220KV substation radiation safety distance of more than 2000 meters 220KV substation, expert point of view 1.220KV substation radiation safety distance of 2000 meters above the 220KV substation, expert opinion in 1. countries "electromagnetic radiation management measures" provisions of more than 100 thousand volts strong electromagnetic radiation works, the provisions ofarticle twentieth: in use around the large equipment or high-frequency electromagnetic radiation equipment, according to the environmental protection and the requirements of city planning, in the planning restrictions or construction of residential housing and the kindergarten sensitive construction zone. 2. according to the electromagnetic radiation produced by UHV power transmissionproject to close contact damage problem, Chinese EMC, Professor Committee Gao Yougang China Electrotechnical Institute Professor Zhao Yufeng, Beijing Institute of labor protectionof the original director Professor Tao Yongxian pointed out thatmany experts at home and abroad have much scientific evidence shows that more than 0.2 micro electromagnetic magnetic field Teslaradiation environment may cause harm to the human body, and it has been confirmed by a large number of domestic and foreign scientific evidence. Note: usually in the 2000 meters outside the substation close to the background value of 0.2 micro Tesla electromagnetic radiation protection experts 3. Anglo American Specialized Committee, after years of research in 1995 the National Health Standard (100 micro Stella) to modify 0.2 micro Stella. 4., Professor Cao Zhaojin of the environment center of China's Center for disease prevention and prevention pointed out that the harm caused by electromagnetic radiation to human health is caused by accumulation, and even if it does not exceed the standard, it can not be said that it is not harmful. 5. during the two sessions in 2005, deputies to the National People's Congress and academician Wang Xiaomo of the Chinese Academy of Engineering suggested that laws and regulations on anti electromagnetic pollution should be formulated as soon as possible so as to protect the health of the people".
