Problems solved by technology

If the design of the lightning protection system is unreasonable, it will easily cause damage to the blades such as breakdown, burning and bursting, which will directly affect the safety of the fan blades.
The existing wind turbine blade lightning protection system suffers from insufficient insulation performance of the internal metal parts, especially the insulation performance of the electrical connection part, and the lightning reception efficiency is not high

Abstract

The invention discloses a wind driven generator blade lightning protection device which comprises a blade tip lightning receiving device arranged at the blade tip of a wind driven generator blade, the blade tip lightning receiving device is connected with a lightning protection system of a wind driven generator through a cable, a heat shrink tube wraps the cable, an insulating sleeve is arranged at the joint of the blade tip lightning receiving device and the cable, and the insulating sleeve wraps the part, connected with the cable, of the tail part of the blade tip lightning receiving device. According to the wind driven generator blade lightning protection device, the risk that a blade body is broken down by lightning due to lightning receiving of an electrical connection part in a wind power blade lightning protection system can be reduced.

Description

technical field [0001] The present invention relates to the technical field of lightning protection for wind turbine blades, and specifically to a lightning protection device for wind turbine blades. Background technique [0002] At present, all wind turbine blades include a lightning protection system. The lightning protection system is mainly composed of lightning receptors installed on the surface of the blade and wires inside the blade body. All lightning receptors are connected to wires, and the wires are installed at the root of the blade. The air-termination device receives lightning and is connected to the lightning protection system of the entire machine through wires, thereby preventing the fiberglass fiber reinforced plastics of the blade body from being struck by lightning. [0003] Wind turbines are generally installed in vast plains, semi-hilly areas and mountain tops, forming obvious protrusions that are prone to lightning strikes. If the lightning protection...
