Title:
RAIL TRANSIT VEHICLE AND METHOD AND SYSTEM FOR ADJUSTING PANTOGRAPH-CATENARY CONTACT PRESSURE OF RAIL TRANSIT VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/058795
Kind Code:
A1
Abstract:
A method of adjusting a pantograph-catenary contact pressure of a rail transit vehicle comprises the steps of: detecting a current motion status parameter and a current pantograph-catenary contact pressure while the rail transit vehicle is traveling; calculating a theoretical pantograph-catenary contact pressure corresponding to the current motion status parameter according to a predetermined corresponding relationship between the motion status parameter and the pantograph-catenary contact pressure; and adjusting the current pantograph-catenary contact pressure according to a difference between the current pantograph-catenary contact pressure and the theoretical pantograph-catenary contact pressure. Also provided are a system for adjusting a pantograph-catenary contact pressure and a rail transit vehicle using the same. The method and system for adjust the pantograph-catenary contact pressure and the rail transit vehicle using the pressure adjusting system can adjust a current pantograph-catenary contact pressure in real-time to be close to a theoretical pantograph-catenary contact pressure, such that a good current collection status is maintained between a pantograph and a catenary.
