Abstract
Description
Verteilungstransformatoren und die Mehrzahl von Leistungstransformatoren werden kaum meßtechnisch überwacht. Die Verteilungstransformatoren mit geringer Leistung werden lediglich mit Hilfe von Hochspannungsschmelzsicherungen geschützt. Bei den Verteilungstransformatoren mit größerer Leistung und bei Leistungstransformatoren erfolgt der Schutz der Isolierung mit Hilfe von verschiedenen Schutzmaßnahmen wie thermischer Schutz, Überstrom- und Überspannungsschutz und Buchholz-Relais. Weiterhin gibt es die Möglichkeit mit Hilfe eines Hydran Sensors, der an den Transformatorkessel angebracht wird, einige gelöste Gase unter bestimmten Umständen nachzuweisen. Eine weitere Möglichkeit ist durch die Bestimmung der Menge und den Zeitpunkt des Auftretens sowie der Gasrate mit Hilfe eines neuen Systems zu ermitteln (Pat.). Darüber hinaus gibt es seit kurzem die Möglichkeit, den Lastzustand mit Hilfe von Temperaturmessung zu überwachen (Beitrag Tenbohlen).Distribution transformers and the majority of power transformers are hardly monitored by measurement. The distribution transformers with low performance are only with the help of High-voltage fuses protected. Both Distribution transformers with greater performance and at Power transformers are used to protect the insulation various protective measures such as thermal protection, overcurrent and Surge protection and Buchholz relays. There is also the possibility with the help of a Hydran sensor attached to the transformer tank will detect some dissolved gases under certain circumstances. A Another possibility is by determining the quantity and the time the occurrence and the gas rate with the help of a new system (Pat.). In addition, there has recently been the option of load status to monitor with the help of temperature measurement (contribution Tenbohlen).
Alle anderen Parameter, wie der Wassergehalt, die Alterungsprodukte und die verschiedenen gelösten Gase in der Isolierung werden durch Probeentnahmen in großen Zeitabständen ermittelt, so dass eine kontinuierliche Überwachung und Bestimmung des Isolierungszustandes und aufbauend darauf eine Lastoptimierung nicht möglich ist. All other parameters, such as the water content, the aging products and the various dissolved gases in the insulation are sampled in large intervals, so that continuous monitoring and Determination of the insulation state and building on it Load optimization is not possible.
Dem im Anspruch 1 angegebenen Verfahren liegt das Problem zugrunde, die verschiedenen Parameter zur Bestimmung des Isolierungszustandes von Transformatoren mit Hilfe geeigneter OFW Sensoren kontinuierlich zu erfassen und damit den Transformator zu überwachen, den Isolierungszustand zu bestimmen und eine Lastoptimierung und Serviceoptimierung zu erreichen.The method specified in claim 1 is based on the problem that various parameters for determining the insulation condition of Detect transformers continuously with the help of suitable SAW sensors and thus monitor the transformer, the insulation state too determine and achieve a load optimization and service optimization.
Die mit der Erfindung erzielten Verbesserungen gegenüber dem Stand der Technik bestehen insbesondere darin, daß durch den gezielten Einbau von geeigneten OFW Sensoren an verschiedenen Stellen von Transformatoren die notwendigen Parameter zur Bestimmung des Isolierungszustandes der Transformatoren kontinuierlich erfasst und daraus Schutzmaßnahmen, Last- und Serviceoptimierung abgeleitet werden.The improvements achieved with the invention over the prior art Technology consists in particular in that through the targeted installation of suitable SAW sensors at different locations on transformers necessary parameters for determining the insulation state of the Transformers continuously recorded and protective measures, load and Service optimization can be derived.
