Advantages of using fiber optic temperature measurement for high voltage cable joint temperature monitoring system-INNO

Sa kasalukuyan, ang domestic cable temperature monitoring technology ay karaniwang wired na koneksyon, sa view ng malakihang high-voltage cable network, Ang mga gastos sa pagtula at pagpapanatili ng linya ay mataas at mahirap ilapat. Mayroon ding mga problema sa pagpapatupad ng teknolohiya, tulad ng temperature-sensitive cable temperature measurement system dahil ang sinusukat na temperatura ay hindi ang aktwal na halaga ng temperatura ay hindi maaaring maging trend analysis, Ang sistema ng pagsukat ng temperatura ng thermistor ay kumplikadong pagpapanatili, fiber-optic distributed temperature monitoring system dahil ang linya ay masyadong mahaba ang mga mamumuhunan ay kadalasang mahirap tanggapin, kaya limitado ang diskarte sa fieldbus sa pagkamit ng maliit na hanay ng real-time na pagsubaybay sa temperatura ng cable, ang malakihang pagsubaybay sa linya ng cable ay tila hindi makakatulong. The fieldbus approach is limited to real-time temperature monitoring of a small range of cables, and is powerless to monitor a large range of cable lines.
In view of the cable with the help of joints connected to form a large-scale network, closely related to each other, any point of failure, may lead to power outages. Samakatuwid, the temperature of the cable joints as a fault characteristic quantity, as long as the temperature of each joint of the power cable can be accurately detected, after analyzing and comparing with the historical data, it can be judged whether there is a potential accident in the corresponding joints, and accurately determine its location, so as to take measures to eliminate the potential accidents.

Adopted a cable joints of the operational status monitoring system, the use of the system can be realized on a wide range of areas within the cable and cable trench temperature online monitoring, when found in a cable joints temperature is too high, the temperature sensing device can be automatically alarmed and through the wireless transmission unit will be the relevant data sent to a remote receiving device, so that the technician in the remote monitoring computer can be aware of the scene of each point of monitoring the situation, timely troubleshooting. The technician can know the situation of each monitoring point at the site on the monitoring computer at the remote end, and troubleshoot in time. This utility model is of great significance for avoiding cable faults and enhancing the safety and reliability of the power grid.

High-voltage cable joints fiber optic temperature measurement system mga tampok

Ligtas na ligtas: fiber-optic intrinsically safe, sensing probe is completely non-electric, anti-electromagnetic interference, do not lead to lightning, intrinsic corrosion, explosion-proof and adapt to harsh environments is significantly better than other means of measurement of electrical sensing.

Pagsubaybay sa real-time: uninterrupted online monitoring/electrical monitoring, realizing the real unattended power system.

Intelligent network: fiber optic sensing network measurement points, both point measurement and distributed measurement; through the LAN, WAN, Internet system connection, can be accessed to the power integrated system, fire protection system, atbp. sa isang mas malakas na power intelligent integrated monitoring system.

Mabilis at tumpak: digital measurement ensures the measurement accuracy and repeatability of the system, while the fast response speed can fully meet the requirements of temperature measurement accuracy and response time of the power system.
