Abstract

Provided is a low-residual-voltage ultra wide band coaxial lightning arrester. The problem that an existing coaxial lightning arrester is few in discharging channel, poor in through-current capability, high in residual voltage caused by insufficient discharging, narrow in transmission band and small in application, easily damages a protected device and causes communication signal distortion is mainly solved. The low-residual-voltage ultra wide band coaxial lightning arrester is characterized in that each main coaxial core (5) comprises an interface portion (53) penetrating insulation supports (51) and an equant core body portion (52) arranged between the insulation supports (51), and a plurality of cavities different in diameter are coaxially arranged inside a main coaxial housing (3). The main coaxial cores of the low-residual-voltage ultra wide band coaxial lightning arrester are even, and impedance matching is achieved by adopting a method of changing the diameters of the cavities of the main coaxial housing. The low-residual-voltage ultra wide band coaxial lightning arrester is wide in band width, large in through-current channel number, high in through-current capacity, rich in high-frequency digital signal frequency spectrum, high in signal fidelity, wide in application range, complete in discharging, low in residual voltage and high in protectiveness on an instrument device behind the lightning arrester.

Description

technical field [0001] The lightning arrester of the invention is mainly used in the microwave communication field, and particularly relates to a low residual voltage ultra-broadband coaxial lightning arrester. Background technique [0002] Reasonable installation of lightning arresters for communication equipment is the first choice to prevent them from being struck by lightning. This kind of lightning arrester must be able to filter out lightning on the one hand, and at the same time, it must not have too much influence on the transmitted communication signal. The coaxial arrester is an arrester designed according to the spectrum distribution of the communication signal and the lightning pulse. The spectrum of the lightning pulse is mainly DC and low frequency components with a frequency below tens of kilohertz, while the communication frequency is a microwave signal with a frequency of several hundred megabytes or more, such as 800~2500MHz. The difference between the two...
