Switchgear/Pad-Mounted Transformer Fluorescent Fiber Optic Temperature Measurement System

Product Overview:

The Fluorescent Fiber Optic Temperature Online Monitoring System for switchgear is an intelligent device designed for measuring temperature at electrical contact points in power switchgear where high temperature requirements exist. It integrates real-time temperature monitoring, early warning, data transmission, temperature display, and overtemperature recording functions into one comprehensive electrical contact temperature measurement device. The system provides an RS485 communication interface and adopts the standard Modbus-RTU communication protocol, enabling rapid integration with third-party terminal devices and computer monitoring systems for networked applications, facilitating centralized data collection and forwarding. Utilizing fiber optic sensing technology, the product offers complete insulation against electromagnetic interference and high voltage, ensuring stable operation in various complex electromagnetic environments with exceptionally high reliability.

Key Features:

• High Insulation Withstand Voltage: Fully optical measurement device. The sensor can withstand over 140 kV power frequency voltage within a 30 cm creepage distance, fully meeting the insulation withstand voltage requirements of switchgear.
• Strong Anti-Pollution Flashover Capability: The fluorescent fiber optic temperature measurement device employs silicone fiber or polytetrafluoroethylene (PTFE) jackets with strong pollution resistance, tailored to different voltage levels, to ensure system safety through signal transmission via specialized optical fibers.
• High Reliability of Temperature-Sensitive Material: The temperature-sensitive substance in the temperature sensor is a rare-earth material exclusively responsive to temperature. The long-term stability of this material has been thoroughly validated, with related systems successfully applied in equipment monitoring for over 30 years.
• Distributed System Architecture with High Stability: A truly distributed system that allows flexible configuration. Each temperature measurement unit operates independently without mutual interference, ensuring that the failure of one component does not compromise the entire system. It exhibits excellent robustness, reliability, and stability.
• Accurate Positioning of Measurement Points: The temperature-sensing probe is compact (φ2.3 mm), enabling precise installation positioning.
• Short Temperature Measurement Cycle with High Real-Time Performance: The single-channel temperature measurement cycle is approximately 1 second,充分 ensuring timely alarm notifications.
