Railway vehicle and storage battery circuit breaker box thereof

Abstract

The embodiment of the invention relates to the technical field of railway vehicles, in particular to a railway vehicle and a storage battery circuit breaker box thereof. The storage battery circuit breaker box comprises a circuit breaker box body, a plurality of mounting seats are arranged on the side wall of the circuit breaker box body, and a mounting positioning plate and a waterproof protection plate are fixedly mounted on the surface of one side of the circuit breaker box body; the mounting positioning plate is of a rectangular annular structure with an opening in the bottom; the waterproof protection plate is located on the inner side of the mounting positioning plate. The waterproof protection plate is of a door-shaped structure and comprises a top plate and vertical plates fixedly connected to the two ends of the top plate. And a perspective window and a switch mounting hole are arranged on the circuit breaker box body on the inner side of the waterproof protection plate. The circuit breaker box can be installed inside a vehicle body, is convenient for maintenance personnel to overhaul and maintain outside the vehicle, and can meet the sealing requirement.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, in particular, to a rail vehicle and a battery circuit breaker box thereof. Background technique [0002] In order to ensure the safety performance of the emergency battery power supply, the existing rail vehicle is equipped with a circuit breaker for the battery. The circuit breaker should be set close to the battery box, but space isolation should be carried out to avoid the explosion of combustible gases (hydrogen and oxygen) released by the battery due to the ignition of the circuit breaker. The existing circuit breaker is generally installed on the battery box nearby through the circuit breaker box, and the battery box is installed on the chassis of the vehicle; since the circuit breaker box is installed under the chassis of the vehicle body, even if the side of the rail vehicle is provided with an apron, it has a certain However, it is still necessary to consider the sealin...

AI Technical Summary

Problems solved by technology

[0003] Since the double-layer stainless steel EMU project of Philadelphia Power Concentration in the United States belongs to double-layer stainless steel cars, the circuit breaker box needs to be installed inside the car body, and at the same time it is convenient for maintenance personnel to repair and maintain the circuit breaker outside the car. The structure of the existing circuit breaker box Unable to meet the requirements, the circuit breaker box needs to be redesigned to meet the maintenance and sealing requirements of the battery
