Wind power bus system

Abstract

The invention provides a wind power bus system. Side plates of a wind power bus are clamped and installed between phase line conductor fixed blocks and limiting ribs of cover plates through steps, theside plates are connected to supporting frames through rotation shafts and pull plates at the same time, the pull plates and the support frames are shortened in order such that the wind power bus isvertically installed in a wind tower, the bottom of a mounting frame is fixedly connected through the supporting frames and an inner wall of the wind tower, the top of the mounting frame presses against wind power bus cover plates through a damper, and mounting frames of adjacent bus systems are symmetrically distributed and installed along the diameter of the wind tower on a support frames. A vibration force is isolated through the damper, through the relative rotation of the pull plates and rotation shafts on the support frames and the relative rotation of the rotation shafts and side platemounting holes, vibration and inertial impact force generated by wind tower swing caused by strong wind flow are buffered, operating risks caused by the looseness of a bus body and a joint part causedby the swinging of the wind tower are reduced, the dynamic and thermal stability of a wind power bus system are good, the safety factor is high, and the bus installation and connection are stable.

[0002] The wind energy resources are huge, and the rapid development and broad prospects of wind power industry technology have brought huge market demand for bus duct products. Wind power bus duct products are an indispensable power supply system for wind power generators. Busway products are generally fixedly installed in the wind tower equivalent to a high-rise building through the installation structure. The wind energy provides energy and also causes the wind tower to swing and generate busway vibration, resulting in the loosening of the bolts of the busway products in the installation structure of the wind tower, and even causing Potential safety hazards caused by the looseness of the main body and joints of the bus duct; only spring supports at the bottom of the wind power bus system cannot effectively resist the high-frequency vibration isolation of the wind. Two wind power bus systems need to be installed in the same wind tower, two Wind power bus system needs synchronous shock absorption

[0003] In the prior art, the busway products in the wind power generation system generally adopt the form of adding heat sink structure on the side plate of the bus bar. The installation gap between the heat sink and the side plate and the contact resistance hinder the transfer and distribution of heat, and the heat dissipation efficiency is low. The temperature rise of the system also increases the user's use cost; the wind tower of the wind turbine is a super high building, and the strong wind causes the wind tower to swing with a large amplitude and frequency. The wind power bus requires strong seismic performance and adopts a dense insulation structure. The anti-seismic performance cannot meet the requirements of wind power generation, nor can it resist the inertial impact caused by the wind swaying wind tower
