Grounding system and rail vehicle having same

Abstract

The invention provides a grounding system and a rail vehicle including the same. The grounding system includes: an in-vehicle grounding structure, and an under-vehicle grounding structure, wherein thein-vehicle grounding structure is a frame type structure, can be distributed on the side wall and the top wall in the vehicle body, and is used for connecting electrical equipment on the vehicle body; the under-vehicle grounding structure is arranged in the length direction of the in-vehicle grounding structure, is connected with the lower part of the in-vehicle grounding structure, is a mesh structure, and can be distributed on the bottom wall outside the vehicle body; and the under-vehicle grounding structure is used to connect the electrical equipment on the vehicle body and is grounded. Therefore, the electrical equipment on the vehicle body can be connected to the in-vehicle grounding structure or the under-vehicle grounding structure in the neighborhood, and then the grounding of the electrical equipment can be realized through the under-vehicle grounding structure, thereby improving the safety and reliability of the grounding of the electrical equipment and preventing lightningstrikes and anti-static effect.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a grounding system and a rail vehicle with the same. Background technique [0002] Following the replacement of stainless steel by aluminum alloy materials, new carbon fiber materials have become one of the preferred materials for the design and manufacture of lightweight car bodies due to their high strength, low expansion coefficient, small heat capacity, and low specific gravity. However, due to objective factors such as composition method and molding process, compared with metal materials such as stainless steel or aluminum alloy, carbon fiber materials have a certain degree of change in their electromagnetic properties such as electrical conductivity and magnetic permeability after forming, which may cause damage to the car body. The weakening of electromagnetic compatibility performance such as magnetic field shielding effectiveness, electric field shielding effective...

Problems solved by technology

However, due to objective factors such as composition method and molding process, compared with metal materials such as stainless steel or aluminum alloy, carbon fiber materials have a certain degree of change in their electromagnetic properties such as electrical conductivity and magnetic permeability after forming, which may cause damage to the car body. The weakening of electromagnetic compatibility performance such as magnetic field shielding effectiveness, electric field shielding effectiveness, grounding impedance, electrostatic protection, lightning strike protection, etc., leads to abnormal working conditions such as communication disorder, control failure, and equipment failure.
