Description
Technical Field
The present disclosure relates to lightning protection technology, and more particularly to a high-resistance electrostatic discharger.
Background
The electrostatic discharger is an electrostatic discharge device for discharging the deposited charges on the surface of the aircraft. For an airplane, mounting enough static arresters on wings and empennages of the airplane is an important measure for static protection, the number of the static arresters of a general small airplane is 3-5, and the number of the static arresters of a large passenger plane is up to about 50. Most of static arresters of the conventional installation machine are composite material type high-resistance static arresters, and parts of the static arresters are all made of composite materials. The electrostatic discharger is installed in three ways, namely, bonding, screw connection or riveting. When in bonding, a paint layer of the aircraft skin needs to be polished, and when in screwing or riveting, holes need to be punched at the installation position of the aircraft skin, so that the static discharger installation surface and the aircraft surface are ensured to form a static passage. Replacement of the static arresters, whether by gluing, screwing or riveting, can cause physical damage to the aircraft skin. Meanwhile, the electrostatic discharger is a non-repairable product, and the service life of the electrostatic discharger is shorter than the service life of an airplane. Moreover, the electrostatic discharger is installed by protruding the appearance of the airplane structure, and the probability of damage caused by mistaken collision during ground operation is high. Compared with airplane structures and parts, the electrostatic discharge brush is a product with relatively high replacement frequency, so that the electrostatic discharger is urgently required to have the characteristics of convenience in use and maintenance and easiness in replacement.
