Large-size cable laying method for wind turbine generator set

Abstract

The present invention relates to a large-size cable laying method for a wind turbine generator set. The method particularly comprises the following steps: a, before lifting a wind turbine generator, arranging and fastening all large-size cables which need to be laid in an upper tower tube; b, after completing lifting the wind turbine generator, removing the large-size cables which are prearranged in the upper tower tube and are used for cable laying at the upper part of the upper tower tube, hoisting the removed large-size cables to an upper tower tube platform by using an overhead hoist, and then drawing the large-size cables to cable connection positions in a cabin by suing a traction apparatus; c, fastening the large-size cables arranged in place so as to complete the laying work of the large-size cables at the upper part of a fan tower tube; and d, removing the rest of the prearranged large-size cables, descending the removed large-size cables layer by layer by using the overhead hoist, fastening the removed large-size cables, and sequentially completing the laying and mounting work of all the large-size cables layer by layer. The large-size cable laying method for the wind turbine generator set has the beneficial effects that the laying operation process is more reasonable and is simple to operate; and the potential safety hazard in the field construction process is reduced and labor intensity of personnel is reduced.

Description

technical field [0001] The invention relates to a large-scale cable laying method of a wind power generating set. Background technique [0002] At present, the installation and laying of large cables in the wind turbine tower mainly adopts the manual laying method. In the wind turbine cabin, the staff use manpower to lower the large cables, and set up a person at intervals in the tower , from top to bottom, and install and lay the laid down cables. There are several major disadvantages in this installation method: [0003] First, the construction cost is high. Due to the harsh environment of the cable laying site and the high labor intensity, a large number of personnel are required to ensure the operation process, and at least 10 people (each unit) should be invested at a time, especially for the use of cables. The unit needs to be equipped with a special crane to cooperate with the operation, and the cost is relatively high. [0004] Second, the work efficiency is low. A...

Problems solved by technology

[0003] First, the construction cost is high. Due to the harsh environment of the cable laying site and the high labor intensity, a large number of personnel are required to ensure the operation process, and at least 10 people (each unit) should be invested at a time, especially for the use of cables. The unit needs to be equipped with a special crane to cooperate with the operation, and the cost is relatively high

[0004] Second, the operation efficiency is low. As mentioned above, it takes two working days to lay a large fan cable. In the case of a large amount of manpower and material resources, the work efficiency is relatively low.

[0005] Third, there are great potential safety hazards. The installation of wind power is a high-altitude operation. The staff need to repeatedly climb on the tower ladder for installation work. There is a great safety hazard for the labor-intensive process that requires a high degree of coordination and cooperation of the staff. Hidden danger
