Embodiment
We will describe in the present invention the blade bearing 11 the mentioned engagement device to the rotor hub 13 of wind turbine (see Fig. 1 a, 1b), it is made up of multiple bolt type fasteners 21 with head 23 and bar portion 25 usually, but the present invention also goes for other engagement device of wind turbine components, the engagement device of the engagement device of part of such as going off course, pylon part or the drivetrain components of use bolt type fasteners or stud type securing member.
When fracture occurs securing member 21, must detect it as early as possible, to avoid contingent catastrophic damage, if the engagement device complete failure between blade bearing 11 and rotor hub 13, blade 10 will be separated from rotor hub 13.Especially, once the fracture of bolt be detected, the rotation of wind turbine blade 10 must be controlled, minimize to make infringement and finally make wind turbine stop.
Fault detection system of the present invention comprises:
Be attached to the conductor wire 31 of the head 23 of the securing member 21 of three blade bearings 11 (or only a blade bearing) by intermediate insulation element, it is arranged to be disconnected by the effect of the weight of its part removed from blade bearing 11 when securing member 21 lost efficacy.
Be connected to the inductive coupler 33 of the end of described conductor wire 31, for powering to the circuit wherein formed and detecting its disconnection when the inefficacy of conductor wire 31 fastener 21 is broken.
Be connected to the programmable logic control device 51 of described inductive coupler 33, for from its receive represent conductor wire 31 disconnection signal and for sending the control system 61 of warning message to wind turbine, regulate the inefficacy being adapted to detect for making it, it usually means in safe mode bootup window or stops it.
In one embodiment (see Fig. 3), inductive coupler 33 comprises the input block 35, remote unit 37, the elementary cell 39 comprising power supply and the output unit 41 that are connected to conductor wire 31.Remote unit 37 with elementary cell 39 magnetic coupling so that voltage V (several millivolts) can be injected into conductor wire 31 and represent that the signal S of the state of circuit formed together with input block 35 by conductor wire 31 can be sent to output unit 47.
The thickness of conductor wire 31 and material will be suitable for the feature of engagement device to guarantee that the inefficacy of fastener 21 is broken by it.It will be preferably made of copper.
In an embodiment (see Fig. 2 a, 2b, 2c), the intermediate insulation element between securing member 21 and conductor wire 31 is insulating binder block 27.
