Point-type optical fiber temperature sensing system

The point-type optical fiber temperature sensing system uses the principle of fluorescence detection to monitor temperature information through optical fibers. It is suitable for temperature sensing monitoring in areas with high temperature monitoring accuracy and narrow spaces, such as switch cabinet contacts, motor stators, transformer windings, etc. Most of these monitored equipment have relatively harsh electrical environmental conditions (electromagnetic field radiation, surges, electrical pulses and other electromagnetic interference), and optical fibers have the characteristics of electrical insulation, intrinsic safety, and immunity to electromagnetic interference, so the probe of the optical fiber sensor can be directly It is installed on the measured point in a contact manner, and monitors the temperature of these devices at "zero distance" to ensure real-time and accurate temperature detection.

Distributed fault location monitoring and pre-alarm system for transmission lines

The distributed fault diagnosis system of the transmission line obtains the traveling wave current at the time of the fault through the monitoring terminals installed on the conductors in a distributed manner, determines the fault location, and uses intelligent identification technology to analyze the fault waveform characteristics and identify the fault as a lightning fault or a non-lightning fault. In the case of a lightning failure, a lightning shielding or counter-strike failure will be further separately issued. The transmission line fault diagnosis method based on distributed monitoring overcomes the shortcomings of traditional methods that require the installation of monitoring equipment on the poles and towers one by one. You only need to install a set of monitoring devices every 20 to 30 kilometers across the entire line to achieve full line fault monitoring. The current technology is advanced and practical, lightning strike/non-lightning fault identification and location system.
