Live working is the power industry to improve reliability and grid security, economic operation and development of a special mode of operation, currently at home and abroad has been widely used in electricity production plays a very important role.Dongguan City is one of the most economically developed areas, electricity supply has grown rapidly, due to the limited land resources, with the poles of the double (multiple) back to the increasing number of overhead transmission lines such as: 500kV by Wan A, B line and 220kV Wan into A, B and four back of the tower line circuit; 220kV Yuexin A, B Dongguan new 220kV line and the A, B and four back of the tower line circuit, 220kV Dong Yue A, B line and the 110kV Datang, dazhang line four back of the tower lines. As a general maintenance operations, single-circuit transmission line maintenance, the adjacent lines which require power, this will inevitably cause blackouts in some areas, seriously affecting the supply of electricity.Moreover, the charged state of the job is not running and equipment limitations, you can always test equipment running, timely detection and elimination of equipment defects and hazards, to ensure uninterrupted power supply and a reasonable flow distribution system, help to reduce power line losses, economic stability to ensure the system is running. Compared with power operation, the device can reduce its operating, convenient scheduling system, greatly reducing the error log tower, mistakenly charged interval, as a result of repeated misuse of power, electrical inspection, and other ground mounted equipment and procedures caused personal injury thus saving the construction investment.In this paper, Dongguan 110kV ~ 500 kV transmission line with towers running multi-loop analysis of device parameters, in accordance with common research methods selected live working air gap is small by typical 500kV line as a line of Dongguan, 500kV Guangzhou-Dongguan-line, 500kV Kun Dong A, B line, 500kV B line, Tung Wai; 220kV Dongguan into A, B line, 220kV Yuexin A, B line, 220kV Dongguan new A, B line, 220kV East jump A, B Datang lines and 110kV, 110kV line dazhang up cattle A, B, C line, 110kV Chen Ling-line, 110kV lines, and Yuan Chang had the following lines of research:In this paper, Dongguan 110kV ~ 500 kV transmission line with towers running multi-loop analysis of device parameters, in accordance with common research methods selected live working air gap is small by typical 500kV line as a line of Dongguan, 500kV Guangzhou-Dongguan-line, 500kV Kun Dong A, B line, 500kV B line, Tung Wai; 220kV Dongguan into A, B line, 220kV Yuexin A, B line, 220kV Dongguan new A, B line, 220kV East jump A, B Datang lines and 110kV, 110kV line dazhang up cattle A, B, C line, 110kV Chen Ling-line, 110kV lines, and Yuan Chang had the following lines of research:1) Live working methods to determine safety, hazard rate and live working method of calculation;2) 110kV ~ 500 kV transmission line with towers of multi-loop operation typical job positions live live working safety analysis, conducted for the typical job position, for the operation of impulse discharge test.3) 110kV ~ 500 kV transmission line with towers of multi-loop security research, a strong electric field of protective equipment including clothing and electrostatic shielding and other protective clothing.4) insulated tools to determine the minimum effective insulation length, bearing tools and operational tools of the minimum effective length calculations and check the insulation.5) 110kV ~ 500 kV multi-circuit transmission line tower with eight kinds of commonly used operations to determine the feasibility of the project and field operations guidelines.
