Abstract

The invention belongs to the technical field of high-speed rail building lightning expelling, and discloses a passive corona field lightning dispeller for a high-speed rail. The passive corona field lightning dispeller comprises a plurality of passive lightning dispellers which are arranged at intervals along a high-speed rail, wherein the passive lightning dispeller comprises a metal outer coverof which the bottom end is provided with an opening, a plurality of discharge through holes are uniformly formed in the metal outer cover, a connecting sleeve is fixed in each discharge through hole in a penetrating manner, a plurality of discharge rods are uniformly fixed on the metal outer cover through the connecting sleeve, an insulating support is arranged on the inner wall of the opening endof the metal outer cover, an electrode is arranged at the bottom of the insulating support, a discharge gap is formed between the electrode and the inner wall of the metal outer cover, and the electrode is connected with a grounding wire and is connected with the ground through the grounding wire. According to the invention, one side of the high-speed rail is provided with a plurality of passivelightning dispellers at intervals so as to effectively eliminate thunderclouds near the high-speed rail and guarantee the operation safety of the high-speed rail; and the passive lightning dispeller has the advantages of being convenient to transport and install.

Description

technical field [0001] The invention belongs to the technical field of lightning driving for building high-speed railways, and in particular relates to a passive corona field lightning driving device for high-speed railways. Background technique [0002] High-speed railway, referred to as high-speed railway, at present, my country's high-speed railway geographical areas are separated by a large span, and there is no backup system. In this case, once a lightning strike occurs, it will cause a permanent failure, and the power supply section will be out of service. The cost and technical requirements are high, the construction standards are strict and demanding, and the management and maintenance are complicated and difficult. Therefore, lightning protection work for high-speed railways is particularly important. In order to reduce the impact of lightning weather on high-speed rail, lightning rods are usually installed on high-speed rail or lightning conductors are installed on ...
