使用GlobeCore設備乾燥變壓器的程序
使用完整的系統來乾燥充滿油的變壓器繞組的干燥程序:特殊的GlobeCore加熱裝置(低頻加熱)+CMM真空加熱變壓器油乾燥系統(根據變壓器的油量,可以提供不同的容量,從400升/小時到15000升/小時不等)。
在變壓器的乾燥過程中,斷開的變壓器繞組直接加熱過程和變壓器油的水分去除過程同時進行。
由於該過程使用CMM真空加熱變壓器油乾燥裝置,因此也會對絕緣油進行脫氣和過濾。
特殊的GlobeCore加熱裝置與變壓器的一次側繞組相連,而二次側繞組則被短路。
在加熱過程中,水分從絕緣紙層移到油中,然後用真空加熱乾燥和脫氣裝置從油中去除。
循環往復,直到繞組升溫到+75oC的溫度後,油中的水份含量低於10ppm。
GlobeCore的特殊加熱裝置是為一次側繞組的額定電流為200A或以下的變壓器設計的。
該系統是完全自動化的。
在運轉過程中,會定期檢查繞組的溫度,以防止過熱。

The procedure for drying transformers with GlobeCore equipment
The drying procedure using a complete system for drying oil-filled transformer windings: a special GlobeCore heating device (Low Frequency Heating) + CMM thermal vacuum transformer oil drying system (depending on the amount of oil in the transformer, different capacities can be offered, ranging from 400 l/hour to 15000 l/hour)
During the drying of the transformer, the processes of direct heating of the windings of the disconnected transformer and the process of removing of moisture from the transformer oil run simultaneously.
Due to the fact that the process uses a CMM thermal vacuum transformer oil drying unit, degassing and filtering of the oil occurs as well.
The special GlobeCore heating device is connected to the primary winding of the transformer, the secondary winding is short-circuited.
During the heating process, moisture moves from paper insulation to the oil, then removed from the oil using a thermal vacuum drying and degassing unit.
The cycle repeats until the amount of moisture in the oil is less than 10 ppm after the windings have warmed up to a temperature of +75oC.
GlobeCore’s special heating device is designed for transformers with primary winding current rating of 200A or less.
The system is fully automated.
During operation, the temperature of the windings is periodically checked to prevent overheating.
