In the power industry, most oil-immersed transformers are provided with capsule type oil conservators at present; when the volume of the transformer oil expands with heat and contracts with cold, the capsule also discharges or sucks external air through the moisture absorber to keep the pressure in the oil storage cabinet constant, and the drying agent in the moisture absorber mainly plays a drying role in absorbing moisture in the air, so that impurities and moisture in the air are prevented from being sucked into the oil, and the cleanness of insulating oil in the transformer oil tank is kept. If the desiccant of the moisture absorber fails after being replaced for a long time, the transformer oil is deteriorated after being directly contacted with unpurified air, and the safe operation of the transformer is seriously influenced; particularly, the large-capacity oil-immersed transformer has relatively large volume and wide contact surface, and the transformer oil is more easily affected with damp; once the transformer is affected with damp, the internal discharge of the transformer is easily caused, and the burning loss of the transformer is caused by the damp; therefore, the drying agent of the moisture absorber needs to be replaced in time, otherwise serious hidden trouble is brought to the safe operation of the transformer.
Once the silica gel of the moisture absorber of the existing transformer loses efficacy and changes color, the color-changing silica gel in the moisture absorber is generally replaced. The problems exist in reality: firstly, the existing moisture absorber still needs to manually observe the color of silica gel on site to know the running state, an online monitoring cloud platform is lacked, and early warning cannot be carried out on operation and maintenance personnel at the first time after abnormality occurs; secondly, current desiccator lacks self-heating hydrofuge device, and silica gel discolours and became invalid after, need move back gas and change, has certain potential safety hazard, and need consume a large amount of manpower and materials, can't carry out cyclic utilization to the drier.
