Problems solved by technology

[0004] However, since the installation position of the three-position transfer switch device 101 is located on the roof 100, the operator must be a professional with corresponding qualifications, and needs to board the roof 100 with the help of professional equipment such as lifts and safety ropes; and the three-position conversion The switchgear 101 is relatively close to the pantograph 102, which will cause potential safety hazards to the personal safety of the operators when switching the state of the rail vehicle

Abstract

The invention provides a three-position switch control system and control method. The control system comprises a control knob arranged in a cab and a three-position switch device arranged on the car roof, the three-position switch device is electrically connected with the control knob, and the three-position switch device and the control knob are both connected with a vehicle-mounted power supply.The three-position switch device is internally provided with limiting switches corresponding to different control positions separately, and turning-on or turning-off of the limiting switches of the different control positions is driven by the rotation of the control knob. The three-position switch control system allows a driver to realize control over the three-position switch device on the car roof in the cab, the operation is simple and fast, operation by climbing to the roof is not needed, the allocation of manpower and material resources and related resources is reduced, and potential safety hazards such as falling or electric shocking during the operation of an operator climbing to the roof are eliminated.

Description

technical field [0001] The invention relates to rail vehicle manufacturing technology, in particular to a control system and a control method for a three-position transfer switch. Background technique [0002] The three-position transfer switch device is set on the high-voltage circuit of the rail vehicle. By switching the switch to different control positions, it can realize the catenary power supply, grounding protection or connection to an external power supply of the rail vehicle. [0003] figure 1 It is a simplified diagram of the installation structure of the three-position transfer switch device in the prior art; please refer to figure 1 . In the prior art, the three-position transfer switch device 101 is generally installed on the roof 100 of the rail vehicle, and is located near the pantograph 102 on the roof 100 . The three-position changeover switch device 101 includes a box body and devices such as a three-position changeover switch arranged in the box body, a...
