Abstract

The invention discloses a dynamic loading platform for a communication sliding ring of a wind generating set. The dynamic loading platform comprises a detection device, a driving device, a first sliding ring and a second sliding ring, wherein the driving device is installed on a bracket; the first sliding ring and the second sliding ring each comprise a rotor and a stator; the stator of the first sliding ring is installed on the bracket; the stator of the second sliding ring is installed on the bracket corresponding to one end of the stator of the first sliding ring; the rotor of the first sliding ring and the rotor of the second sliding ring are connected through a linkage device; the rotor of the first sliding ring is also electronically connected to the rotor of the second sliding ring; at least one of the stator of the first sliding ring and the stator of the second sliding ring is connected with the detection device; and the driving device is in transmission connection with the linkage device, such that synchronous rotation of the rotor of the first sliding ring and the rotor of the second sliding ring is realized. According to the dynamic loading platform disclosed by the invention, dynamic controllable detection of the communication sliding ring is realized by simulating the practical operation state of the communication sliding ring; and a new scheme is provided for dynamic loading tests of the communication sliding ring of the wind generating set.

Description

technical field [0001] The invention belongs to the field of wind power generation, and in particular relates to a dynamic loading platform for a communication slip ring of a wind power generating set. Background technique [0002] Wind energy is an inexhaustible, inexhaustible and non-polluting renewable resource that is naturally produced. It is a kind of available energy provided to human beings due to the work done by air flow, so it is widely used by people. Due to the progress of the scientific level and the characteristics of clean and environment-friendly wind energy itself, wind energy has been applied to the power generation industry. Wind power generation converts the kinetic energy of the wind into mechanical kinetic energy through wind turbines, and then converts the mechanical energy into electrical kinetic energy. The wind power is used to drive the windmill blades to rotate, and the speed of rotation is increased through the speed increaser to promote the gen...

Problems solved by technology

Due to the limitation of the communication slip ring structure, the relative rotation method is mostly used for detection at present, and the multimeter is used to measure the on-off and insulation of each channel or all the channels are connected with weak current (DC24V) signals to judge whether the slip ring is good or not. , such a solution cannot comprehensively and effectively test the communication slip ring, because each channel of the communication slip ring not only conducts weak current signals, but also conducts electrical signals such as CAN communication, serial communication, DC550V, AC380V, AC230V, etc., and cannot pass through analog communication Dynamic and controllable rotation detection is performed on the actual running state of the slip ring, which leads to a low yield rate of the repaired communication slip ring

There is currently no good solution for dynamic loading testing
