The utility model discloses a high-voltage bus bar contact temperature measurement system based on optical transmission, which comprises a bus bar contact part, a temperature sensor, a temperature controller, a field instrument, a first infrared emitter diode, a. Busbar temperature monitoring represents the most critical parameter in preventing catastrophic switchgear failures. Statistical analysis from electrical utilities worldwide reveals that thermal-related failures account for 30-40% of all high voltage switchgear breakdowns, with average repair costs. Temperature monitoring in high-voltage busbar systems is vital for preventing faults, yet difficult due to electrical hazards, limited accessibility in switchgear cabinets, and interference risks in traditional contact-based methods. Gradual degradation, poor connections, and electrical imbalance. One of the most reliable indicators of system health is temperature. in high-voltage switchgear cabinets. The sensors are composed. Critical busbar joints and terminations are the "silent" risk centers of an industrial plant, where undetected loose connections or oxidation lead to overheating, catastrophic fire hazards, and unplanned downtime.
