Minimization of gas content in liquids used for heat exchange and insulating purposes

摘要

In a device for minimising cracked gases in heat transfer and insulating liqs., (esp. transformer insulating liqs. and high temp. organic heat transfer liqs.),a vacuum compensated by the creation of a hydrostatic pressure is generated and maintained in a degassing vessel through which the insulating fluid flows as result of e.g. the thermal siphon effect, and the liq. is continually kept low in gas content. Also claimed is an arrangement for ensuring the function of the action principle according to the above on change in the liq. volume. The removal of the cracked gases from the system, even in cyclically (esp. daily) loaded transformers, without contact between the insulating liq. and other gases is ensured by means of a membrane between the transformer insulating liq. and a buffer liq. which communicates with an upper, closed vessel contg. an inert gas (esp. nitrogen).
