Catenary-Checking on-Line Monitor Device
CRRC Qingdao Sifang Co., Ltd.: It is in the leading position in the industry in the research and development and manufacturing of high-speed EMUs, intercity EMUs, and urban rail vehicles. It manufactured China's first 200 km/h high-speed EMU and the first "Fuxing" EMU. Its main models are CRH2A, CRH380A, CR400AF series, etc. The market share of high-speed EMUs is nearly 50%.
In catenary on-line monitoring applications, infrared (IR) thermal imaging offers key benefits:
-
Hotspot Detection in Electrical Contacts: IR identifies overheating in catenary joints, pantograph contacts, or connectors, preventing arcing and power supply failures.
-
Non-contact High-voltage Surveillance: Non-invasive IR scanning safely monitors live catenary systems without disrupting electrified rail operations.
-
Real-time Thermal Fault Warning: IR systems detect temperature spikes in real time (e.g., due to abrasion or ice accumulation), enabling prompt maintenance to avoid service interruptions.
-
Component Degradation Monitoring: Thermal imaging maps temperature gradients on catenary wires and supports, helping assess wear and optimize replacement schedules.
