FJINNO provides distributed temperature measurement fiber optic, distributed fiber optic sensing system, fiber optic temperature measurement host, with good quality and reasonable price. Please feel free to contact us for detailed technical solutions.

Power cables are an important type of power transmission equipment and an important component of the power transmission and distribution system, occupying a significant proportion in the power system Therefore, monitoring cable temperature and preventing cable fires have always been highly valued by leaders of various manufacturers The traditional linear temperature sensing system was originally used for cable fire prevention, which was established earlier With the passage of time and technological progress, linear temperature sensing systems have shown many shortcomings and drawbacks, and can no longer meet technical requirements FJINNO has independently developed a distributed fiber optic temperature measurement system, which enhances the monitoring of cable fire prevention The principle and structure of a distributed fiber optic temperature measurement system, as well as its application and effectiveness in fire prevention of television tower cables.

The distributed fiber optic temperature measurement system mainly consists of fiber optic temperature measurement host, industrial control computer, monitor, network interface, ಇತ್ಯಾದಿ. The fiber optic temperature measurement host is the heart of the temperature measurement system The internal components include modules such as pulse lasers, optical wavelength division multiplexers, photodetectors, broadband linear amplifiers, and signal processing units The fiber optic temperature measurement host emits laser pulses, receives backward Raman light waves returned from the fiber optic, converts optical signals into electrical signals, and processes them to calculate the distribution of temperature values in the entire measurement area The industrial computer processes the data output by the temperature measurement host, displays and stores the temperature change status values of each temperature measurement point through configuration software, or achieves remote data sharing through the network.

The distributed fiber optic temperature measurement system utilizes the principles of spontaneous Raman scattering and optical time-domain reflection generated during the transmission of light in the fiber optic to obtain spatial temperature distribution information Fiber optic is both a sensor component and a transmission channel, and its characteristics remain unchanged for decades. Except for external forces causing fiber optic breakage, it will not malfunction and does not require replacement Continuous detection points with a wide detection range can be used for both point based detection and spatial area detection All equipment is concentrated in one cabinet, and only temperature sensing optical fibers are available on site A few optical fibers can complete large-scale and multi-point monitoring Easy to install, easy to lay, resistant to high voltage and strong electromagnetic fields, high temperature and radiation, resistant to radio frequency and electromagnetic interference, flame retardant, explosion-proof, corrosion-resistant, able to work in various harmful environments, inherently safe Widely used in power equipment overheating warning, fire protection, leakage monitoring, oilfield logging, and other aspects.

The distributed fiber optic temperature monitoring system is a new technology that is currently emerging in the field of temperature measurement. It can continuously and real-time monitor the temperature of various equipment such as cables in the power system, accurately identify hot spots, enable operators to timely understand the operation situation, eliminate hidden faults, and prevent the occurrence of malignant accidents With the continuous development, research, and improvement of distributed fiber optic temperature measurement systems, this technology will undoubtedly play an increasingly important role in the safe operation of power systems.
