Quick-repairing method for urban power distribution room

Abstract

The invention provides a quick-repairing method for an urban power distribution room. The quick repairing method can solve the problems that during power distribution room repairing, the blackout time is long, cost is high and efficiency is low, and can guarantee normal power supply for residents. The quick-repairing method comprises the following steps that firstly, a set of high-voltage reserved interfaces are additionally arranged at the second 10kV wire inlet end of the power distribution room, and a first low-voltage reserved interface and a second low-voltage reserved interface are additionally arranged on a 0.4kVI section bus and a 0.4kVII section bus of the power distribution room respectively; secondly, a box transformer substation vehicle arrives at the site, a bypass circuit cable of the box transformer substation vehicle is unfolded; thirdly, a superior switch at the second10kV wire inlet end is turned off, a wire inlet cable of a second high-voltage switch and a ring main unit are disconnected, and protection is carried out; fourthly, working is carried out according to the sudden failures of the ring main unit or the routine repairing of the ring main unit or failures of any transformer. The quick-repairing method is suitable for the power distribution room, and also suitable for fast repairing of network distribution box type transformers, column transformers, switching stations and other network distribution devices.

Description

technical field [0001] The invention relates to the field of rapid repair operations of distribution network terminal equipment such as power distribution rooms and box-type substations in urban distribution networks, and in particular to operations such as rapid repair of power distribution rooms in urban areas and routine maintenance without power failure. Background technique [0002] With the construction and development of the city, there are more and more high-rise buildings, and the emergency and living equipment such as building fire protection and high-pressure water pumps have higher and higher requirements for the reliability of power supply. Power outages are basically not allowed, and grid construction in developed urban areas is basically To achieve dual power supplies, but for the internal equipment of the power distribution room, it is still a single equipment, such as the ring network cabinet. Although the incoming line of the ring network cabinet is dual po...
