Technical Field

Background
The transformer respiratory system comprises a transformer oil storage cabinet, a breather and a breather communicating pipe, and the transformer breather is used for filtering moisture in air flowing into the transformer oil storage cabinet.
There are two types of respirators available today:
First kind: a common silica gel respirator;
Second kind: maintenance-free silica gel respirator.
The maintenance-free silica gel respirator adopts a mode of heating wet silica gel to remove excessive moisture in silica gel particles, so that the maintenance-free silica gel respirator is kept for a long time.
Because the number of transformer accidents caused by the blockage of a common silica gel respirator is insufficient, the safe operation of the transformer is seriously endangered, the smooth of a transformer respiratory system is currently checked manually, whether the oil surface at the lower end of the respirator has bubbles or not is checked regularly every day, but the method has the problems that labor is consumed, blockage cannot be found timely, the judgment is difficult to realize by naked eyes, and the like, for example, whether the oil surface at the lower end of the respirator has the bubbles or not can not be judged when the oil surface at the lower end of the respirator has no bubbles during observation.
Currently, such airflow sensors are lacking.
For the maintenance-free respirator, when the silica gel is heated and dehumidified, the transformer is selected to be used for 'spouting' outwards, so that the moisture heated from the silica gel is prevented from entering the transformer.
Currently, such airflow sensors are lacking. Therefore, there is a problem in that maintenance-free respirator products are difficult to put into practical use.
