Moisture absorber

Moisture absorber

The moisture absorber is also known as the respirator, and slao called a silica gel tank or slow flow moisture absorber. On the transformer, the moisture absorber is usually connected to the oil storage tank, and there is a white or blue silica gel adsorbent inside for cleaning and Dry the debris and moisture in the air entering the transformer (or transformer) oil conservator due to the change of transformer oil temperature to ensure the insulation strength of the transformer oil and ensure the normal operation of the transformer. Large and medium-sized transformers generally have respirators. This kind of respirator is a glass container filled with a hygroscopic agent such as color-changing silica gel, and an oil cup containing transformer oil is arranged at the bottom of the respirator. The cup contains transformer oil, and the air entering the main transformer is first filtered through the transformer oil to remove dust. Then the water is filtered through silica gel, so that the air that finally enters the main transformer is relatively dry and pure, which can prevent the problem of aging of the insulating oil.

The hygroscopic agent is blue before it absorbs moisture, and the color is bright after being put into the respirator, which is convenient for observation.
