Abstract

The invention relates to a connecting device of a slip ring assembly and a gear box and a wind driven generator, and relates to the technical field of wind driven generators. The connecting device ofthe slip ring assembly and the gear box comprises a slip ring rotor, a limiting plate, a plurality of sealing elements and a plurality of power supply cables, the slip ring rotor comprises a cable mounting chamber and an adapter terminal mounted in the cable mounting chamber, the limiting plate is installed in the cable installation chamber and located on one side, facing the gear box, of the adapter terminal, the limiting plate is provided with limiting holes which are the same as the power supply cables in number and correspond to the power supply cables one to one, the plurality of power supply cables are fixedly connected to the adapter terminal correspondingly and arranged correspondingly in the corresponding limiting holes in a penetrating manner, and the sealing elements are connected with the limiting plate and the power supply cables to be used for blocking gaps between the limiting holes and the corresponding power supply cables. According to the connecting device of the slipring assembly and the gear box and the wind driven generator, the technical problem that in the prior art, the connecting device of the slip ring assembly and the gear box cannot well prevent gear box oil from entering the cable installation chamber is solved.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to a connection device between a slip ring assembly and a gear box and a wind power generator. Background technique [0002] The fan pitch system of the wind turbine needs power supply and signal and data transmission. Since the fan is in a rotating state, it cannot be directly powered by cables. It must use a rotary joint. This rotary joint is called a pitch slip ring. The slip ring rotor and The main shaft is connected to form the fan rotor, and the slip ring stator is fixed on the gearbox to form the fan stator. The pitch system mainly relies on the carbon brushes and slides between the slip ring stator and the slip ring rotor to complete the power supply when the fan rotates. The most basic requirement that the pitch slip ring needs to realize is: reliable power, signal and data transmission. The oil-proof requirements of the pitch slip ring after the motor is ma...
