Abstract

The embodiments of the present application relate to the technical field of rail vehicles, and in particular, relate to a rail vehicle and a battery circuit breaker box thereof. The battery circuit breaker box includes a circuit breaker box body; a plurality of mounting seats are arranged on the side wall of the circuit breaker box body, and an installation positioning plate and a waterproof guard plate are fixedly installed on one side surface; the installation positioning plate is The bottom is provided with a rectangular ring-shaped structure with openings; the waterproof shield is located inside the installation positioning plate; the waterproof shield is a door-shaped structure, including a top plate and vertical plates fixedly connected to both ends of the top plate; A perspective window and a switch installation hole are arranged on the circuit breaker box inside the guard plate. The circuit breaker box can be installed inside the vehicle body, and is convenient for maintenance personnel to perform inspection and maintenance outside the vehicle, and can also meet sealing requirements.

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...
