The device has a weather mast (3) consisting of pipelines (5), a stand (6) and a lightning protection cage (4), where the pipelines are connected with each other. The protection cage is formed from the pipelines that are arranged around 90 degrees. A heater is arranged in the pipelines, and is formed by multiple electrical heating wires. The heating wires are connected with a voltage supply, and are grounded separately from the masts. The heater is regulated separately or by a system control of a wind energy system. The heating wires of the individual weather mast are parallelly switched. |
