Novel anti-thunder blade and conducting resin applied to novel anti-thunder blade

Abstract

The invention discloses a novel anti-thunder blade. The novel anti-thunder blade comprises a blade body. The two sides of the blade body are fixedly provided with one or more grooves which are symmetrically formed. The interiors of the grooves are coated with heat insulation coatings. The heat insulation coatings are filled with conducting resin layers. The surfaces of the conducting resin layers are flush with the surface of the blade body. The blade body is further provided with a plurality of lightning arresters, and the adjacent lightning arresters communicate with each other through wires via the conducting resin. The novel anti-thunder blade is simple in structure and convenient to use; a user buries the wires for connecting the lightning arresters into the conducting resin in advance, the lightning arresters on the blade can effectively communicate with each other, and therefore the lightning receiving area of the novel anti-thunder blade is increased; and the grooves are internally provided with the heat insulation coatings, the heat produced after the conducting resin layers receive lightning can be effectively prevented from damaging the internal structure of the blade, the heat insulation coatings are made of heat insulation materials for the medium temperature, and heat with the temperature of 100 DEG C or above can be effectively insulated.

Description

Technical field [0001] The invention relates to the field of lightning protection, in particular to a new type of lightning protection blade and a conductive adhesive applied to it. Background technique [0002] With the rapid development of the building and aircraft industry, lightning protection facilities have become an indispensable part. The safety of lightning protection has always been a high priority of all sectors of society. The existing blades are mostly installed with air-termination devices. In this way, the air-termination area is limited due to the limited size of the individual air-termination system; [0003] At present, the lightning protection system of wind turbine blades mainly comes from the lightning protection model of buildings. The main principle is to install metal tips on the blades or install metal conductors on the surface of the blades to form an upward pilot advantage and realize lightning connection and conduct lightning current. However, due to th...

[0002] With the rapid development of the construction and aircraft industry, lightning protection facilities have become an indispensable part. The issue of lightning protection safety has always been attached great importance to by all walks of life. Most of the existing blades are equipped with lightning receptors. In this way, the air-termination area is limited due to the limited size of the individual air-termination device;

[0005] The traditional conductive adhesive is mainly based on matrix resin and conductive filler, and the conductive filler is mostly a kind of metal or semiconductor; this kind of conductive adhesive cannot be used in the field of large current, especially lightning current conduction, because it is too large current; there are conductive adhesives containing a variety of metal conductive fillers on the market, but there are problems of thermal conductivity and electrical conductivity that are not as good as metal bonding.
