Hydropower generator lower guide shoe temperature measurement and monitoring device

Abstract

This utility model discloses a temperature measurement and monitoring device for the lower guide bearing of a hydro-generator, relating to the field of condition monitoring and fault diagnosis technology for large-scale hydropower equipment. It includes a bearing base, multiple bearing supports, a tray, a lower guide bearing, a distributed temperature sensing layer, and intelligent acquisition units. It also includes an external monitoring host and a reliable data transmission network module. The reliable data transmission network module is a highly interference-resistant communication link connecting each intelligent acquisition unit to the monitoring host. This design can significantly improve monitoring accuracy and coverage. By densely deploying monitoring points to capture localized overheating, it completely solves the problem of missed detections caused by sparse temperature measurement, truly reflecting the overall temperature field of the bearing and bearing. Furthermore, it reduces the number of fragile long analog signal lines, and the sensors and communication links designed to withstand harsh environments greatly reduce the risk of false alarms and missed detections caused by sensor failure and signal interference.
