Description

[0001] APPARATUS FOR HOLDING GENERATOR CABLE [0002]

The present invention relates to a cable fixing device for a wind turbine, and more particularly, to a cable fixing device for a wind turbine that can compensate for a change in length due to twisting of a cable generated by rotation of a nacelle of a wind turbine, And more particularly, to a cable fixing apparatus for an installation.

Wind turbines such as wind turbines are an environmentally friendly power generation facility that converts wind-induced rotational energy into electrical energy. It is part of a renewable energy business, which is well received in today's world where the need for global environmental protection is highlighted.

These wind turbines can be roughly divided into nacelle and tower. In the nacelle, a plurality of blades rotated by the wind are mounted in a circumferential direction at predetermined intervals on a hub, and the center of the hub is connected to the drive shaft of the rotor. When the blade is rotated by the wind force, the rotational energy is transmitted to the rotor.

Inside the nacelle, a generator connected to the rotor is also built in. As the rotor rotates, the generator converts the rotational energy into electrical energy.

In addition, various devices are arranged inside the nacelle. In particular, a device requiring power or various sensors are connected to a power system unit or a control unit by a cable.

These cables are arranged along the inside of the towers supporting the nacelle and connected to various devices inside the nacelle.

On the other hand, the wind turbine is configured such that the nacelle performs a 'yawing motion' and rotates correspondingly to the change of the wind direction to generate maximum output at all times. Such a system is called a yaw system.

However, when the nacelle performs a yawing motion, the cable connected to various devices built in the nacelle causes a twist in the ellipse. If the cable is twisted, the position of the cable inside the tower is severely changed, and the cable is dirty or severely damaged.

Further, since the cable is pulled in the direction of the nacelle as the cable is twisted, the length of the cable is changed in the vertical direction, and the cable may be broken when the cable is connected without any margin.

 1 shows a state in which a cable 3 is fixed inside a tower 1 of a conventional wind power facility. A fixing block 4 having a plurality of through holes 4a passing through the cable 3 is bolted to the inner frame 2 and a plurality of guide plates 5 are arranged at the midpoint of the cable 3, (3).

However, since the conventional cable fixing method is not a method of holding the cable 3, the downward load acts largely due to the load of the cable 3 itself. If some cable 3 is damaged and needs to be replaced, (3) is difficult to be attached and detached, which results in an excessive maintenance load, maintenance time and cost for the operator.
