Description
Technical Field
The invention relates to a wire clamp of power system substation equipment, in particular to an electromagnetic shielding type equipment connecting wire clamp of a substation.
Background
Electromagnetic radiation refers to the propagation of a portion of the electromagnetic energy emitted by a field source away from the field source and out-diffusing the energy in the form of electromagnetic waves. Electromagnetic waves are waves in which electric and magnetic fields move and transfer energy, including radio waves, microwaves, infrared rays, visible light, ultraviolet rays, x-rays, gamma rays, and the like. In urban (town) areas, substations are built, and electric fields, magnetic fields and electromagnetic radiation exist inside and around the substations; the main reason for generating electric field, magnetic field and electromagnetic radiation is that the live equipment and live conductor of the substation have power frequency voltage and power frequency current. In order to prevent the electric field, the magnetic field and the electromagnetic radiation generated by the charged equipment from affecting the human body, the electric field, the magnetic field and the electromagnetic radiation energy need to be controlled within a certain range. The concern of electric and magnetic fields affecting human health was first originated in the united states of the last century, western europe, etc., where electric power facilities were first used on a large scale. In the research work on electromagnetic fields and human health by the international committee for non-ionizing radiation protection, according to the relevant research results, the international committee for non-ionizing radiation protection issued a guideline in 1998 to specify that the safety value of the power frequency electric field intensity to the public is 4kV/m and the limit value of the power frequency magnetic induction intensity to the public is 100 microtesla. This standard was officially recommended by the world health organization in 2007 and adopted by most countries. The power frequency electromagnetic radiation protection safety value of part of the countries (organizations) in the world is specified in a table 1-1.
TABLE 1-1 part of State (organization) Power frequency electromagnetic radiation protection safety value regulations
The 'electromagnetic radiation environmental protection management method' in China is attached to a power frequency strong radiation system specified by 'electromagnetic radiation construction project and equipment directory', wherein two items are related to power transmission and transformation engineering, and the three items comprise: a power transmission and transformation system with the voltage of more than 100 kV; and the current is over 100A.
The experts such as the teaching just at the high points of the main committee of the Chinese electromagnetic compatibility committee, the teaching of Zhaoyefeng of the Chinese electro-technical society, the teaching of pottery and Yongyu of the original institute of labor protection in Beijing city, and the like indicate that: there is a lot of scientific evidence at home and abroad that the electromagnetic radiation environment with the magnetic field higher than 0.2 microtesla is likely to cause harm to human body. Professor soviet Thomsom the Chinese disease prevention center environment suggests that the harm of electromagnetic radiation to human health is accumulated, and the harm cannot be said to be caused even if the electromagnetic radiation does not exceed the standard.
The power frequency electric field, the power frequency magnetic field and the electromagnetic radiation are arranged around the connecting wire clamp connected with the high-voltage device of the transformer substation, when the conductor connected with the wire clamp or an electric power system where the device is located breaks down, performs switching operation, overhauls the device, tests and changes the operation mode of the electric power system, large current can be instantly conducted or interrupted on the wire clamp, the electromagnetic radiation intensity at the moment is high, and the influence on external electromagnetic interference is also large. Therefore, it is necessary to finely study the electromagnetic radiation generated by the connection clip for shielding the high voltage conductor and the high voltage equipment. How to reduce the generation of the power frequency electric field and the power frequency magnetic field of the connecting wire clamp and prevent the transmission of the power frequency electric field and the power frequency magnetic field to the outside creates a safe electromagnetic environment for social public spaces and transformer substation operators, and is still an important subject of research in the field.
