Abstract

The invention relates to a combined energy transmission device and a wind generating set. The combined energy transmission device comprises a plurality of coaxially arranged energy transmission parts, and in every two adjacent energy transmission parts, at least part of one energy transmission part is located in the other energy transmission part; and each energy transmission part comprises a rotor and a stator which are in running fit and electrically connected with each other, the rotors of the energy transmission parts are independently arranged and are in insulated connection, and the stators of the energy transmission parts are independently arranged and are in insulated connection. According to the combined energy transmission device and the wind generating set of the embodiments, transmission of at least one of mechanical energy, electric energy, optical energy, hydraulic energy and the like can be met, limitation of installation space can be reduced or avoided, and construction is facilitated.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a combined energy transmission device and a wind power generating set. Background technique [0002] During the operation of the wind turbine generator set, there are electromechanical coupling energy transmission of multiple systems. Such as blades and hubs, impellers and nacelles, nacelle bases and towers, etc., there are both mechanical energy conversion and electrical energy transmission, including mechanical energy and hydraulic transmission. [0003] In order to adapt to the above working conditions, the commonly used solutions are collector rings, smooth rings, electric slip rings, lightning protection slip rings, etc. All the above equipments meet the operating conditions of wind turbines to a certain extent, but when two or more equipments need to be installed in one system, due to the limited installation space, the installation structure is complicated and the cons...
