Problems solved by technology

This causes the fixed cables on the tower to follow the twisting of the nacelle, and in severe cases, it will cause the twisted cables of high-power fans to fail, or even break the cables
[0003] In order to prevent the twisted cable failure of high-power fans, two solutions are usually adopted. First, the cable uses anti-twisted cables, but the requirements for cable quality are relatively high, and the cost is too high
Second, design a mechanical connection system that prevents twisted cables, but requires high contact resistance at the contact points of the system

Abstract

The invention discloses a cable twisting prevention connecting device for a high-power fan. The cable twisting prevention connecting device for the high-power fan comprises a cabinet cable, a cabinet current collection rotating shaft, a tower current collection ring, a cabinet current collection rotating plate and a tower cable. The cable twisting prevention connecting device has the advantages of low contact resistance of contacts and manufacturing cost, twisting prevention and the like.

Description

technical field [0001] The invention belongs to the field of high-power fan manufacturing, and in particular relates to a high-power fan anti-twisting cable connection device in the transmission of the high-power fan. Background technique [0002] The electrical energy of high-power wind turbines is output to the power grid by cables fixedly laid on the tower. Due to the need for high-power wind turbines to capture wind energy, the nacelle must perform yaw movements according to the wind direction to ensure maximum capture of wind energy. This has caused the fixed cables on the tower to twist along with the nacelle, and in severe cases, it will cause the twisted cables of high-power fans to fail, or even break the cables. [0003] In order to prevent the twisted cable failure of high-power fans, two solutions are usually adopted. First, the cable uses anti-twisted cables, but the requirements for cable quality are relatively high, and the cost is relatively high. Second, de...
