Faseroptische Sensormessung der Messeranschnitttemperatur

Why does the knife switch need temperature measurement

With the increasing demand for power reliability, a certain component in a substation heats up severely and loses its original function, which means it will cause major power outages to users or major equipment damage accidents to the substation. The knife switch components of the substation, due to their rotatability and frequent operation, have always been the most vulnerable components to overheating and damage in the substation. In the safe operation system of power equipment, temperature is an important parameter to verify the normal operation of primary equipment. The connection parts of power equipment, due to changes in climate, equipment foundation, processing technology, environmental pollution, severe overload operation, Kontaktoxidation, und andere Gründe, cause loose crimping, insufficient pressure, changes in contact parts, and ultimately increase contact resistance. When current passes through, the temperature rises, causing equipment aging, insulation decline, und in schweren Fällen, triggering arc short circuits, burning out equipment, expanding the scope of equipment damage, reducing equipment service life, and even easily causing a fire and explosion of the equipment, especially the dynamic and static contact parts of the movable knife switch, which have a high failure rate, all of which constantly threaten the safe operation of power equipment.

What are the temperature measurement methods for the knife switch

The traditional inspection method uses manual operation or automatic program control of unmanned aerial vehicles with dual light cameras (visible light cameras and thermal infrared cameras) for inspection. Dann, visible light photos and infrared photos are exported from the unmanned aerial vehicles. Dann, by comparing the visible light photos, the knife switch equipment and contact points on the infrared photos are found and marked. Endlich, the marked infrared photos are read using temperature measurement software to display the temperature of the knife switch contact points. Jedoch, due to the fact that there are at least dozens of infrared photos taken during a single inspection, and each photo contains more than 20 knife switch devices, manually marking the contact points of the knife switch on the infrared photos is very cumbersome and time-consuming. Darüber hinaus, it is difficult to directly find the knife switch equipment from infrared photos, and it is often necessary to compare visible light photos taken at the same time to determine the position of the knife switch in infrared photos. Manual marking may result in missed or incorrect labeling. Gleichzeitig, the inspection frequency of substations (at least once a day) is high, and the manual marking work is very time-consuming. There is an urgent need for a more efficient method to replace it.
The traditional temperature measurement methods for substation knife switches include infrared thermal imaging temperature measurement, point infrared temperature measurement, Und kabellose Temperaturmessung. The above temperature measurement methods either have low real-time performance, hohe Kosten, or are prone to damage and cannot automatically adjust the temperature. Sie können nicht automatisch aufschneiden oder schließen, wenn die Temperatur des Messerschalters plötzlich ansteigt.

Messerschalter-Glasfaser-Temperaturmessgerät

Der Fluoreszenzfaseroptisches Temperaturmesssystem ist ein Gerät, das die elektrische Hochgeschwindigkeits-Teleskopstange so steuert, dass sie schnell arbeitet und abschaltet, wenn die Temperatur des Messerschaltarms einen bestimmten eingestellten Wert überschreitet, Vermeidung von Schäden an elektrischen Geräten durch hohe Temperaturen des Messerschalters. Noch wichtiger, aufgrund des großen Temperaturunterschieds zwischen den beiden Seiten des Temperaturdifferenzgenerators am Messerschalter, Die Stromerzeugung ist groß, und der Lüfter kühlt gleichzeitig auf einer Seite des Temperaturdifferenzgenerators ab. Der Temperaturdifferenzgenerator nimmt eine große Wärmemenge auf. Wenn die Temperatur des Messerschaltarms unter die eingestellte Temperatur fällt, Die Steuerung steuert die elektrische Hochgeschwindigkeits-Teleskopstange, um den Messerschaltarm schnell zu schließen, Erzielung einer intelligenten und automatischen Steuerung des Messerschalters, Einsparung von Arbeitskräften und materiellen Ressourcen, and reducing economic losses; Zeigen Sie das Temperatursignal direkt an und steuern Sie das lokale Alarmgerät zum Senden von Informationen, Bereitstellung einer Remote-Alarmausgangsschnittstelle für den Anschluss an andere Informationssysteme. Senden Sie die Alarm- und Dateninformationen an die Überwachungszentrale, um den Status des unbemannten Umspannwerkschalters in Echtzeit zu überwachen, rechtzeitige Reparatur, und wirtschaftliche Verluste vermeiden.
