Abstract
Przedmiotem zgłoszenia jest sposób suszenia układu izolacyjnego urządzenia elektroenergetycznego przy użyciu metanolu, w którym układ izolacyjny urządzenia elektroenergetycznego umieszcza się szczelnej obudowie urządzenia elektroenergetycznego (2), po czym usuwa się ze szczelnej obudowy (2) tlen, poprzez wymuszenie przepływu azotu, następnie w obieg azotu wprowadza się pary metanolu do osiągnięcia zawartości metanolu w celulozie na poziomie do 8%, po czym reguluje się stężenie metanolu w cyrkulującym azocie w przedziale od 0,1 do 1,0 g/l i prowadzi się proces przepływowego osuszania do osiągnięcia założonej wielkości średniego zawilgocenia celulozy na poziomie niższym niż 1%, przy czym mieszanina azotu i metanolu w trakcie przepływowego suszenia jest przetłaczana przez osuszacz (4) wykonany na bazie sita molekularnego. Przedmiotem zgłoszenia jest także system realizujący ten sposób.The subject of the application is a method of drying the insulating system of a power device using methanol, in which the insulating system of a power device is placed in a tight housing of the power device (2), and then oxygen is removed from the tight housing (2) by forcing the flow of nitrogen and then into the nitrogen circulation. methanol vapors are introduced until the methanol content in the cellulose reaches 8%, then the methanol concentration in the circulating nitrogen is adjusted from 0.1 to 1.0 g/l and the flow drying process is carried out until the assumed average cellulose moisture content is achieved at a level lower than 1%, and the nitrogen and methanol mixture is forced through a dryer (4) based on a molecular sieve during flow drying. The subject of the application is also a system implementing this method.
