Problems solved by technology

However, since the method of measuring the contact pressure changes the original structure of the pantograph, the pantograph-catenary contact pressure cannot truly and accurately reflect the dynamic relationship between the pantograph and catenary

Abstract

The invention discloses a non-contact type pantograph and catenary arcing energy detection method and system, and relates to the contact net detection technology. The method comprises the steps of 1, collecting pantograph and catenary arcing characteristic ultraviolet light signals; 2, converting the pantograph and catenary arcing characteristic ultraviolet light signals into electrical signals Vd; 3, calculating the arcing ultraviolet energy (unit: microwatt) according to the electrical signals; 4, calculating the arcing energy Warc according to the formula that Warc=a*Wuv+b, wherein preferentially, a ranges from 5 to 20, and b ranges from -20 to 20.

Description

technical field [0001] The invention relates to catenary detection technology, especially pantograph-catenary arc energy detection technology. Background technique [0002] The catenary is an important part of the traction power supply system, and the pantograph is the key component for the electric train to obtain electric energy from the catenary. The good dynamic contact performance of the catenary and the pantograph is the premise guarantee for the normal operation of the electric train. However, the good mechanical contact between catenary and pantograph is restricted by many other factors, such as catenary suspension, catenary wire material, defects of pantograph slide plate and track irregularity, etc. If the above influencing factors exist, there may be a slight bad contact between the contact wire and the contact surface of the pantograph, and arcing may occur between the pantograph and catenate. The occurrence of this discharge phenomenon not only deteriorates the...
