Description

technical field

[0001] The invention relates to a method for upgrading and transforming power distribution lines, and belongs to the technical field of electric power overhead transmission. Background technique

[0002] With the continuous development of society and economy, the society's demand for electricity is increasing day by day, and the 10kV voltage level of the medium-voltage distribution network is difficult to meet the requirements of the existing power supply. With the increase of regional load density, many problems have appeared in 10kV power supply, such as: insufficient power supply capacity, many outgoing lines, crowded corridors, excessive line loss, low voltage at the end of the line, short power supply radius, and construction of substations. So much to wait. The use of 20kV voltage level in the medium-voltage transmission network can improve power supply capacity, reduce voltage loss, reduce line power loss, increase power supply radius, and reduce line...

Examples

Embodiment Construction

[0050] Example, the medium-voltage distribution network in a certain area adopts a frequency of 50 Hz, a voltage level of 10kV, and a three-phase AC transmission. The total length of the line is 16 km. The original bare wire line has been transformed into an insulated line. , can not meet the needs of users, insufficient power supply capacity, many outgoing lines, crowded corridors, excessive line loss, low voltage at the end of the line, and short power supply radius. The present invention goes through the steps of survey, check calculation, evaluation, design, implementation, test, acceptance, experiment and trial, and includes the following methods:

[0051] The first step of survey: line survey is the basis for establishing the best plan, which determines the rationality of the plan and the economic, technical indicators, construction and operating conditions of the line; use infrared night temperature measurement and shooting, and use ground probe (24) pole tower foundatio...
