Abstract

Prema ovom pronalasku, elektromotor uronjen u izolujuću tečnost sastoji se od elektromotora, hermetički zaptivenog rezervoara u kojem je smešten elektromotor, izolujuće tečnosti rasporedjene izmedju elektromotora i rezervoara, pri čemu rezervoar sadrži deformabilni uredjaj kroz koji gas i tečnost ne mogu da prodju i čiji je oblik promenljiv, tako da je promenljiva i prihvatna zapremina koja je u stanju da primi izolujuću tečnost izmedju rezervoara i elektromotora, izolujuća tečnost u potpunosti ispunjava prihvatnu zapreminu u rezervoaru, a elektromotor uronjen u izolujuću tečnost nadalje se sastoji od uredjaja za stvaranje pritiska radi podešavanja oblika deformabilnog uredjaja tako da se pritisak izolujuće tečnosti u rezervoaru održava na odgovarajućem nivou radi sprečavanja isparavanja izolujuće tečnosti.
