[0002] Transformers are often equipped with desiccant devices to absorb moisture entering the transformer. Traditional desiccant devices use disposable silica gel to absorb moisture from the air entering and exiting the transformer's oil conservator. When the silica gel becomes saturated with water, it must be replaced to maintain the desiccant's moisture absorption function. Currently, there are maintenance-free desiccant devices. Their advantage is that when a self-feedback system detects that the silica gel is saturated with water and has lost its moisture absorption function, it transmits this information to the system, heats and drains the silica gel, and ensures that the silica gel can continue to absorb moisture for recycling.
