Abstract

The Invention provides a high-voltage interlocking protection device and method for a rail vehicle. The device comprises a first key locker assembly, a second key locker assembly, a third key locker assembly, a first protective grounding switch assembly and a second protective grounding switch assembly; the first key locker assembly corresponds to a first protective grounding switch and is used for controlling rising and falling of a corresponding pantograph; the second key locker assembly corresponds to a second protective grounding switch and is used for controlling rising and falling of a corresponding pantograph; and the third key locker assembly corresponds to the first protective grounding switch, the second protective grounding switch, corresponding room power supplies and converters of various carriages and is used for controlling the corresponding protective grounding switches, corresponding traction converter grounding switches and interlocking protection of various circuitsbetween the room power supplies. The device is simple in structure, safe and reliable, and by means of the method, operation normalization and standardization of a high-voltage safety interlocking system are guaranteed, and the personal safety of operating personnel during vehicle inspection and maintenance is guaranteed.

Description

technical field [0001] The invention relates to the technical field of locomotive high voltage protection, in particular to a rail vehicle high voltage interlock protection device and method. Background technique [0002] At present, the high-voltage safety interlock system is an important part of the high-voltage safety protection system of rail vehicles, which is related to the personal safety of train operators, the protection and safe use of high-voltage equipment. [0003] In recent years, as more and more rail vehicles have been put into use, the high-voltage safety protection system of train vehicles has gradually become the focus of current work. With the extensive promotion and application of domestic AC25kV urban rail vehicles, the safety and reliability of the high-voltage system of vehicles Sexual demands are getting higher and higher. [0004] However, most of the existing schemes operate the traction converter directly, without considering the impact of the hi...
