Abstract

The invention relates to a dynamic experimental testing system of a pantograph. The dynamic experimental testing system of the pantograph mainly comprises a high voltage terminal data acquisition device, a low voltage terminal data acquisition device and a testing station. The system can comprehensively monitor various indicators of the pantograph according to the working state of the pantograph, and the whole system is organically integrated by combining the digital image processing technology, the testing technology and the optic fiber communication technology. Indexes of the time at which the arc is generated, the arcing rate and the like can be accurately obtained, the hard spot of the pantograph, the dynamic height curve of a pantograph plate, and the dynamic contact pressure of a pantograph catenary are measured, furthermore, the position at which the abnormal value is located is obtained according to the kilometer post information tested by the system, and thus the subsequent relevant adjustment on the pantograph catenary is facilitated.

Description

technical field [0001] The invention relates to a pantograph dynamic test system mainly aimed at high-speed trains. Background technique [0002] At present, the main scheme of the dynamic test of the pantograph is to test each item that needs to be tested separately, without combining the detected parameters to analyze the pantograph-catenary current receiving performance in a unified manner. [0003] After searching, it is found that the Chinese utility model patent: CN200920350834.X discloses "high-speed railway catenary-pantograph system current receiving performance test equipment", which adopts the combination of high-voltage side and low-voltage side, contact measurement and non-contact measurement The combined method realizes the dynamic height measurement of pantograph-catenary dynamic contact force, hard point, arc detection, and pantograph, but its defect is that the power supply module on the high-voltage side is unstable. Due to the special high-voltage environm...
