Fluorescent Fiber Optic Transceiver Module

The fluorescent fiber-optic temperature monitoring system is designed for the early prediction of faults and fires—triggered by insulation aging or poor electrical contact—within high-voltage power equipment such as switchgear, disconnectors, cable joints, and transformers. Equipment such as switchgear, disconnectors, cable joints, and transformers operate under conditions of high current and high voltage; consequently, their electrical operating environments are relatively harsh (characterized by significant electromagnetic interference, including electromagnetic radiation, surges, and electrical pulses). However, optical fibers possess inherent characteristics such as electrical insulation, intrinsic safety, and immunity to electromagnetic interference. This allows the sensor probes to be installed directly in contact with the specific points under measurement, thereby enabling “zero-distance” monitoring of temperature anomalies in switch contacts and cable joints to predict potential faults and prevent the occurrence of electrical fires.

描述

Features

(1) High Dielectric Strength

This is a fully optical measurement device. Within a creepage distance of 30 cm, the sensor can withstand power-frequency voltages exceeding 140 kV, thereby fully meeting the dielectric strength requirements for switchgear.

(2) Strong Resistance to Flashover Caused by Contamination

Tailored to different voltage levels, the fluorescent fiber-optic temperature measurement system employs special optical fibers—sheathed in either highly contamination-resistant silicone or PTFE—for signal transmission, thereby ensuring the overall safety of the system.

(3) High Reliability of Temperature-Sensing Materials

The temperature-sensing element within the sensor consists of a rare-earth material that is sensitive exclusively to temperature. The long-term stability of this material has been thoroughly validated, and related systems have been successfully deployed in equipment monitoring applications for over 30 years.

(4) Distributed System Architecture with High Stability

As a truly distributed system, it offers flexible configuration options. Each temperature measurement unit operates independently without mutual interference; consequently, a failure in a single component will not result in the failure of the entire system. This design ensures excellent robustness, reliability, and stability.

(5) Precise Positioning of Measurement Points

The temperature-sensing probe features a compact size (φ 2.3 mm), allowing for the precise positioning of the installation location.

(6) Short Measurement Cycle and High Real-Time Performance

The temperature measurement cycle for a single channel is approximately one second, thereby fully guaranteeing the timeliness of alarm notifications.
