Annular construction power distribution network wiring structure

Abstract

The invention discloses an annular construction power distribution network wiring structure, which adopts an annular power distribution backbone network. A branch feeder line loop is equipped with dual-path incoming switches. The annular power distribution backbone network is firm in frame and high in power supply reliability; the network is concise in structure, is obvious in hierarchy and convenient to manage, is suitable for the power distribution network of various single power sources , multiple power sources, various loads and multichannel feeder lines, and is high in universality; the wiring structure is simple in wiring and needs small number of devices, is flexible and simple to run, is safe and simple to operate, is easy to expand and is high in flexibility; through general device, the effects of easy purchase, running, operation and maintenance are achieved; and the technical and economic performance is good and adaptability is good.

Description

【Technical Field】 [0001] The invention belongs to the field of power supply and distribution for thermal power generation construction, and relates to thermal power project construction and various construction power distribution wiring structures, and in particular to a wiring structure of a ring-shaped construction power distribution network. 【Background technique】 [0002] Thermal power engineering construction and various construction electrical loads mainly include lifting and lifting equipment, mixing equipment, water pumps, fans, electric heating, cutting, welding, vibrating and compacting equipment, various motors, illuminators, etc. One or several construction power transformers are routinely set up on the construction site and distributed to the electrical equipment in a radial pattern after voltage conversion. [0003] From the actual operation point of view, due to the lack of detailed system design for construction power supplies, weak power distribution grids and poor...

AI Technical Summary

Problems solved by technology

[0003] From the actual operation point of view, due to the lack of detailed system design of construction power supply, the distribution network frame is weak and poor in reliability; the construction power equipment is numerous and miscellaneous, and as the project progresses, various types of power equipment come in and out frequently, making it difficult to effectively manage; construction The work area is vast, and the staff's wiring is relatively random. Unauthorized connections lead to system disorder, frequent power accidents on the construction site, and easy tripping by leaps and bounds, resulting in expanded accident consequences; chaotic wiring is difficult to find fault points, and it takes a long time to restore power after a fault. It often leads to increased losses; the construction power management personnel are not professional enough, the operation is not standardized or even misoperation, etc.
