High-voltage ground switch

Abstract

The invention provides a high-voltage ground switch, comprising an outside-vehicle assembly mounted on a base plate of a vacuum circuit breaker and an inside-vehicle assembly mounted in the vehicle, wherein the outside-vehicle assembly comprises a contact, an elastic contact seat matched with the contact, a swinging arm, a soft connecting line, a ground pole and a rotating shaft; the elastic contact is positioned at both ends of the vacuum circuit breaker, the contact is positioned on the swinging arm, the swinging arm is mounted on the rotating shaft through a transmission assembly, and the soft connection line is used for connecting the swinging arm and the ground pole; the inside-vehicle assembly comprises a bearing bracket, a handle assembly, an interlocking mechanism and a rotating wheel, and the rotating wheel drives the swinging arm into motion through the transmission assembly; and the handle assembly and the rotating wheel are coaxially horizontally mounted for driving the rotating wheel to rotate; and the interlocking mechanism is used for restricting the rotation of the rotating wheel. The high voltage ground switch provided by the invention has the advantages of effectively avoiding misoperation of motor vehicles or motor train sets by drivers and conductors due to various reasons, thus ensuring the security of the drivers and conductors and motor vehicles.

Description

technical field [0001] The invention belongs to the field of high-voltage equipment for electric locomotives and EMUs, and in particular relates to a high-voltage grounding switch. Background technique [0002] Nowadays, the running speed of tram locomotives and EMUs on main railway lines is getting faster and faster, and the technological content is getting higher and higher. On the requirements of integrated control; in addition, the safe operation of locomotives is an eternal theme in the development of railways. [0003] When electric locomotives and EMUs run on the main railway line, unexpected failures occur and they need to be temporarily stopped for maintenance and in the process of repairing electric locomotives and EMUs in various locomotive depots, such accidents often occur: When drivers or maintenance workers often Due to negligence or forgetting to disconnect the main circuit breaker on the roof and lower the pantograph when dealing with emergency situations, ...
