7 - The dehydrating breather
The dehydrating breather is provided at the
entrance of the conservator of oil immersed equipment such as Transformers and reactors.
The conservator governs the breathing action of
the oil system on forming to the temperature change of the
equipment, and the dehydrating breather removes the moisture and
dust in the air inhaled and prevents the deterioration of the Transformer oil due to moisture absorption.
Construction and Operation
See Fig. (20) The dehydrating breather uses
silica - gel as the desiccating
Agent and is provided with an oil pot at the
bottom to filtrate the inhaled air. The specifications of the
dehydrating breather are shown in Table (1) and the operation of
the component parts in Table (2).
