INNO faseroptische Temperatursensoren ,Temperaturüberwachungssysteme.
Power equipment will generate heat during normal operation. Due to environmental factors, Verarbeitungstechnologie, und andere Faktoren, the connection of circuits, Ausrüstung, etc. may not be tightly pressed, the pressure may not be sufficient, and the contact between contacts may change, resulting in an increase in contact resistance and a more pronounced heating phenomenon. Long term exposure to this will accelerate the aging of power equipment lines, leading to a decrease in insulation performance of power equipment. In schweren Fällen, it can also trigger arc short circuits, reduce the service life of equipment, und schwere Stromunfälle verursachen. Especially in the dynamic and static contact parts of the isolation switch, the main transformer lead, and the cable head, the phenomenon of overheating is more prominent, with a high failure rate, and such problems occur every year. Gegenwärtig, monitoring methods still rely on regular completion by staff, was zeitaufwändig ist, arbeitsintensiv, extremely inefficient, and cannot be reached.
Fiber optic sensing technology is a new technology developed in recent years, which is a new concept of sensing technology derived from the development of optical fibers and fiber optic communication technology. Fiber optic sensors detect and measure changes in external physical quantities by analyzing the wavelength of light. As a new member of the sensor family, fiber optic sensors have the following obvious advantages:
1) Anti-elektromagnetische Interferenz, Elektrische Isolierung, Korrosionsbeständigkeit, and good safety. A pair of electrical insulation, suitable for high voltage places;
2) Hohe Empfindlichkeit, high temperature accuracy, lange Lebensdauer, and comprehensive performance superior to existing monitoring methods:
3) Leicht, klein, Flexibel, suitable for narrow spaces;
4) The measurement object is wide and has little impact on the measured medium;
5) Einfache Vernetzung und Durchführung von Temperaturmessungen in mehreren Bereichen.

Designziele von faseroptisches Temperaturmesssystem
Das faseroptische Temperaturmesssystem muss die folgenden Anforderungen erfüllen:
1. Echtzeiterkennung der Kontakttemperatur der Schaltanlage
2. Lokalisieren Sie die Adresse der Schaltanlage für abnormale Temperaturen genau;
3. Das faseroptische Temperaturmesssystem sollte in der Lage sein, die dreiphasigen Kabelköpfe A rechtzeitig und genau zu erkennen, B, und C in der Schaltanlage; Ein, B, C
4. Dreiphasiger statischer Kontakt; Die Temperatur der Innenumgebung der Schaltanlage kann in Echtzeit erfasst werden, und das Temperaturalarmsignal kann über den faseroptischen Temperaturmess-Host an den vorhandenen Brandmelder im Instrumentenkontrollraum übertragen werden. The alarm can be displayed on the industrial control computer in the fire duty room, and information can also be sent to relevant personnel via mobile phone SMS.
