The pantograph obtains the electric energy required by the running of the traction motor and the power equipment on the train from the contact network, and is an important part of a high-speed electric power train, wherein the carbon sliding plate is a part in direct contact with the pantograph and the contact network and is a first gateway for obtaining the electric energy. Carbon slides generally consist of an aluminum alloy chassis and graphite bars, bonded together by a conductive adhesive. The carbon slide plate is also internally provided with an air inflation cavity so as to achieve the purpose that the carbon strip can be automatically exhausted and bow-falling after the carbon strip is abraded to the limit or the carbon strip is broken. The carbon slide plate is an important condition for ensuring the stable operation of the high-speed electric power train and plays an important role in the operation of the high-speed railway. The carbon sliding plate is guaranteed not to have faults in the running process of the motor train unit and early warning of the faults is an important subject in high-speed railway operation, and the carbon sliding plate has important significance in online detection and warning of the characteristics of the carbon sliding block.
The principle of the pantograph carbon slide block monitoring and warning module of the ultrasonic electric locomotive is that two ultrasonic probes are designed, the ultrasonic probes respectively send out specific transmitting signals and send out the signals through an ultrasonic transmitting module, the sent ultrasonic waves can generate changes including periods, frequencies, amplitudes and the like when passing through a measured object, and the structural characteristics and defect distribution of the measured object can be detected by receiving echo waves of two reflected waves. The module has the following functions: (1) the alarm can be given when the height of the carbon strip is less than 5 mm; (2) the air leakage condition of the joints or seams of the sliding plate can be monitored in real time or at regular time; (3) the crack in the middle of the carbon sliding plate can be monitored; (4) the dropping condition of the carbon block with large area can be monitored.
