Abstract
The invention relates to a method for measuring a distorted electric field under a 1000KV ultra-high voltage AC line, which comprises three parts, namely a method for measuring the power-frequency distorted electric field in a residential building under the 1000KV ultra-high voltage AC line, a method for measuring the power-frequency distorted electric field on the balcony of the residential building under the 1000KV ultra-high voltage AC line and a method for measuring the field strength on the roof platform of the residential building under the 1000KV ultra-high voltage AC line. The method has the important practical significance in specifying the measurement of the power-frequency distorted electric field in the national power transmission and distribution project and scientifically carrying out the environmental protection and the environmental evaluation of the power transmission and distribution project, and solves the embroilment problem due to the electromagnetic environment of the power transmission and distribution project.
Description
Technical field
The invention belongs to high voltage power transmission and transforming engineering electromagnetic compatibility field, is a kind of 1000KV distortion electric field measurement method in extra-high voltage AC circuit specifically.
Background technology
Along with improving constantly of the continuous quickening of power grid construction paces, people's living standard, power grid construction also constantly runs into the puzzlement of environmental protection aspect problem.The electromagnetic problems initiation complaint and the dispute of house owed by a citizen take place to close on, cross over because of transmission line of electricity throughout the country frequently, the incident of group's visit in recent years constantly rises, even the masses obstruct the incident of project of transmitting and converting electricity construction to happen occasionally, this brings difficulty not only for the construction of electrical network, and has had a strong impact on the safe operation of electrical network.
Eliminate the electromagnetic environment influence of the defeated Cheng Zaocheng that exchanges work for maximum magnitude ground; the environmental protection inspection and acceptance stage after the project of transmitting and converting electricity construction environmental evaluation stage in early stage, construction; carry out electromagnetic environment monitor work; and project of transmitting and converting electricity put into operation the back actual environment index is scientifically measured evaluation, be the fundamental state policy of China environmental protection.Because high-voltage alternating aerial power transmission line power frequency distortion electric field measurement method disunity; make that different results appears in different mechanism for monitoring when concrete engineering being carried out environmental monitoring and estimating; cause measurement data and judge very big deviation occurring; unnecessary misunderstanding and many disputes have been caused with this; this not only scientifically protects environment unfavorable to China, and has seriously hindered the construction and the operation of the defeated journey of exchanging work of China.
Summary of the invention
The objective of the invention is measurement for standard China project of transmitting and converting electricity power frequency distortion electric field, and solve the dispute problem that causes owing to the project of transmitting and converting electricity electromagnetic environment, and power frequency distortion electric field measurement method under a kind of scientific and effective 1000KV extra-high voltage AC circuit is provided.
To achieve these goals, the present invention includes three parts: power frequency distortion electric field measurement method in the house owed by a citizen under the 1000KV extra-high voltage AC circuit; Power frequency distortion electric field measurement method on the house owed by a citizen balcony under the 1000KV extra-high voltage AC circuit; Field intensity measuring method on the house owed by a citizen roof platform under the 1000KV extra-high voltage AC circuit, wherein:
Power frequency distortion electric field measurement method in the house owed by a citizen: the power frequency electric field in the room, area inner measuring place outside distance wall and other fixed objects 1.5m, and measure maximal value, as estimating foundation.As not satisfying above-mentioned and the requirement metope distance, then get the floor space planar central as measurement point, but the 1m at least of the distance between measurement point and peripheric fixture body;
Power frequency distortion electric field measurement method on the house owed by a citizen balcony: when the physical dimension of balcony satisfied in the house owed by a citizen field intensity measurement point arrangement requirement, the field strength measurement method on the balcony was identical with field intensity measuring method in the house owed by a citizen; If the physical dimension of balcony does not satisfy field intensity measurement point arrangement requirement in the house owed by a citizen, then should measure at the balcony middle position;
Field intensity measuring method on the house owed by a citizen roof platform: the area inner measuring power frequency electric field outside wall and other fixed objects 1.5m around the distance, and draw the measurement maximal value, if the physical dimension of house owed by a citizen roof platform does not satisfy this condition, then should measure at the platform middle position.
The present invention is the measurement of standard China project of transmitting and converting electricity power frequency distortion electric field, scientifically carries out the environmental evaluation of environmental protection and project of transmitting and converting electricity, and solves because the dispute problem that the project of transmitting and converting electricity electromagnetic environment causes has important practical significance.
