Problems solved by technology

[0004] Non-conductive materials often use non-metallic materials, such as ceramics, PVC, etc. Ceramics are expensive and not flexible enough, while PVC is not rigid enough, so the thickness of the material needs to be increased to meet the requirements of supporting the busbar pipe, and the cost will be relatively high. high
After the insulating rubber is sleeved on the busbar tube, it is supported by a metal mounting bracket. However, the tower of wind power generation is prone to shake when it is subjected to wind force, and the busbar tube will shake with the tower tube, which will cause the insulating rubber to be easily worn and leak electricity.

Embodiment Construction

[0029] Such as figure 1 As shown, this embodiment introduces a power transmission system of a wind power generating set, which is arranged in the tower 9 and includes a plurality of bus pipes 1, flexible connections 2 and installation brackets 3, and the plurality of installation brackets 3 are fixedly connected to the tower 9, the mounting bracket 3 is arranged vertically and evenly, the bus pipe 1 is fixedly installed on the mounting bracket 3, and the bus pipe 1 is connected by a flexible connection 2. When the tower tube 9 shakes, the busbar tube 1 and the mounting bracket 3 will shake together with the tower tube 9. During the shaking process, the misalignment between the busbar tubes 1 is adjusted through the flexible connection 2 to reduce power transmission Internal stress between systems.

[0030] combine figure 1 As shown, when the tower tube 9 shakes, the busbar tube 1 and the mounting bracket 3 will also shake. Generally, one busbar tube 1 is provided with two mo...

Abstract

The present invention relates to the technical field of wind power generation, in particular to an electric energy transmission system of a wind power generating set, which includes a plurality of bus pipes, flexible connections and mounting brackets, the bus pipes are arranged vertically, and the bus pipes are connected to each other through flexible connections. The outer side of the bus pipe is covered with an insulating sleeve, the insulating sleeve is riveted or fixedly connected to the bus pipe, and the mounting bracket is lapped or clamped and fixed with the insulating sleeve. After the insulating sleeve is set on the outside of the bus pipe, the mounting bracket is fixed by lapping or clamping the insulating sleeve to fix the bus pipe, that is, the mounting bracket and the bus pipe are separated by the insulating sleeve. At this time, the mounting bracket can be made of iron, etc. Metal, with low cost and stable structure, finally achieves the effect of stably supporting the busbar and achieving insulation.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to an electric energy transmission system of a wind power generating set. Background technique [0002] As a new type of clean energy, wind power has been widely promoted all over the world. The electricity generated by wind power is transmitted through the power transmission system, and the power transmission system is set inside the tower of wind power generation. [0003] The existing power transmission system includes multiple busbars and flexible connectors, the busbars are connected by flexible connectors, the busbars are connected to the tower through the installation bracket, the installation bracket includes a fixed seat and a movable seat, and the fixed seat is horizontally fixed on the On the inner side wall of the tower, the movable seat and the fixed seat are detachably and fixedly connected, and the busbar is located between the fixed seat and the movabl...
