Wind Turbine Lightning Protection And Monitoring Systems

Номер: GB0002469520A
Принадлежит:

A wind turbine hub 8 and nacelle 4 assembly includes means for conducting lightning between the hub and the nacelle. The hub is rotatably mounted on the nacelle and includes a hub conductor 26 connecting to a blade supported by the hub. The lightning conducting means includes a conductive track 40 and a terminal 30, 32 which confront and are displaceable relative to each other, one of the track and the terminal being mounted on the hub and connected to the hub conductor and the other being mounted on the nacelle. The terminal includes a terminal main body 30 spaced from the track and a sacrificial conductive terminal extension 32 e.g. a wire brush extending from the terminal main body towards the track. The brush wears with time to produce a gap. The brush is vapourised to plasma on a lightning strike. There is also an inductive sensor surrounding a conductor sending signals to a wind farm monitoring system to identify which turbine has been struck and which sacrificial elements need replacing ...

Power Cable

Номер: GB2459658A
Принадлежит:

A power cable 10 comprises a metal conductor encased in a first outer sheath 11, and further encased, partially along the length of the cable, in a second outer sheath 12, 13, 14 which influences the pattern of deformation of the cable under mechanical stress. Preferably the cable is a jumper cable having two terminals 15, 16. The conductor is preferably a tin coated copper braid. Each insulating layer is preferably a heat shrink tubing and the second insulating layer being disposed at end regions and/or at a central region along the length of the cable.
