Temperaturmessung des Umspannwerkstransformators mithilfe von faseroptischen Sensoren

Substation temperature monitoring device

There are many types of substations, including different kV substations, 110kV-Umspannwerke, substation design, box type substations, 35kV-Umspannwerke, intelligent substations, substation construction, 220kV-Umspannwerke, intelligent substations, substation engineering, Hochspannungs-Umspannwerke, usw. The temperature of substation joints is an important parameter, and substations are widely used power equipment in the construction and renovation of power system urban networks. The substation integrates and installs various electrical equipment inside the substation. Due to the concentration of various electrical equipment in a relatively enclosed environment, when the substation is in use and in a powered state for a long time, the electrical equipment will generate a large amount of heat during operation. Due to the high temperature requirements of substations, wenn diese Wärme nicht rechtzeitig abgeführt werden kann, it will affect the overall normal operation of the substation and easily cause damage to the electrical equipment inside the substation. Zum Beispiel, the electrical equipment installed in the low-voltage room of a substation has a large heat dissipation capacity. When the internal temperature of the low-voltage room of the substation is too high, it can lead to the burning or short circuit of the internal electrical equipment. daher, real-time online monitoring of the temperature of various equipment in the substation is important.

The temperature measurement requirements for substation equipment mainly include transformers, Hochspannungs-Leistungsschalter, Trennschalter, Sammelschienen, Blitzableiter, Kondensatoren, Reaktoren, usw.

The main business of substation fiber optic temperature measurement enterprises is substation fiber optic temperature measurement. The performance of the substation fiber optic temperature measurement monitoring host is superior, the technical strength is internationally leading, und der Preis ist angemessen.

Fiber optic temperature measurement system for substation main transformer

The main transformer is generally an oil immersed transformer, which can use a fluoreszierendes faseroptisches Temperaturmesssystem,

According to the IEEE/ANSI or IEC Transformer Operating Load Guidelines, the upper load limit of a power transformer is set based on the winding temperature and/or top oil temperature of the transformer during normal or emergency operation. During each operating cycle of the transformer, its upper load limit can also serve as a basis for determining the remaining insulation life of the transformer. daher, users need to understand the actual hot spot temperature of the transformer during operation and optimize the load, maximize the asset value of the equipment, and minimize the risk of equipment overheating, sudden reduction in insulation life, and/or failure.

The independently developed transformer winding fiber optic temperature measurement device is used to monitor the critical operating temperature of power equipment. The monitored temperature data can be used to control the equipment cooling system and establish load levels. The transformer winding fiber optic temperature measurement device is easy to connect with the user’s local computer network or system, and provides temperature data to the dispatch center.
