Problems solved by technology

However, the current operating system has the following defects: (1) The operating environment is limited
However, urban distribution networks are often located in areas with crowded spaces and narrow streets, and usually do not have the conditions to carry out bypass operations, and the environment for bypass operations is limited
(2) Safety protection is difficult
It is difficult to protect equipment such as load switches and cable joints on the job site, and there are shortcomings such as difficult management and many safety hazards

Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] like figure 1 , which is a schematic diagram of teaming in the bypass operation and maintenance method of the cable lifting with the hoisting platform applicable to complex terrain in the present invention, using two crawler-type lifting work platforms 1 and a crawler-type cable retracting device 2 to complete the bypass operation. , the live operator 3 and the bypass cable 4 go up the tower synchronously once, and complete the replacement of the isolating...

Abstract

The invention relates to the technical field of power transmission line maintenance operation, in particular to a bypass operation maintenance method suitable for lifting of a cable along with a hoisting platform in complex terrains. The bypass operation maintenance method is characterized in that a maneuvering team consisting of two crawler-type lifting working platforms and a crawler-type cablewinding and unwinding device is adopted to complete bypass operation, a hot-line worker and a bypass cable synchronously go up to a tower at one time, and replacement of a disconnecting switch is completed by means of auxiliary lifting appliances on the working platforms. Compared with the prior art, the bypass operation maintenance method has the beneficial effects that 1) the crawler-type three-vehicle maneuvering team is strong in maneuverability and is more suitable for the bypass operation of farmland cultivated land or other complex terrain environments; 2), the hot-line worker and the bypass cable can synchronously go up to the tower without going up to and going down from the tower for many times, so that the labor intensity is low, and the work efficiency is higher; 3), field workrequirements are met, large-scale equipment such as a cable laying vehicle can be replaced to complete bypass work, so that the flexibility is improved; and 4), extra cranes are not needed to be additionally arranged, so that resources are saved.

Description

technical field [0001] The invention relates to the technical field of power transmission line maintenance operations, in particular to a bypass operation maintenance method in which cables in complex terrain are lifted and lowered with a hoisting platform. Background technique [0002] The principle of opening 10kV distribution network lines without power failure or short-term power failure through the bypass operation system is simple, safe and reliable. A temporary power supply line can be quickly built through bypass load switches, flexible cables, quick terminals and intermediate connectors. Carrying out various maintenance operations in the state of power failure of the maintenance equipment can ensure the normal power consumption of each branch user, ensure the safety of personal and equipment, and improve the reliability of power supply. But the current operating system has the following defects: (1) The operating environment is limited. At present, the distribution...
