Problems solved by technology

[0004] ①During the heating and dehydration process after the silica gel is damp, it is necessary to convert water vapor into condensed water before it can be discharged from the bottom of the device, which is greatly affected by the environment, and the heating and reduction process takes a long time and the efficiency is low; In the online dehydration and reduction of silica gel, the inner wall of the glass bottle is prone to frost. Even if the water outlet and air inlet are equipped with a heating device, there is a risk of freezing and blockage when the heating fails or the power is cut off; ③During the long-term heating and dehydration process of silica gel, due to The uncertainty of breathing of the main equipment increases the probability of inhalation of steam; ④The dust and harmful gases in the air are not filtered out, and the dust will lead to the increase of impurities in the insulating oil, SO 2 Such harmful gases will accelerate the aging of the breathing capsule and bring hidden dangers to the safe operation of the main equipment; ⑤The waterproof sealing ring in the control box cover is prone to aging with the service life and changes in the natural environment, which will increase the risk of water ingress

Abstract

A maintenance-free dehydrator with air in and out at the upper part, its heating assembly and its control method. The interior of the rain cover forms an evaporation and condensation chamber, the diameter of the rain cover is larger than that of the dehydrator body, and a breathing channel is formed between the bottom inner wall of the rain cover and the top outer wall of the dehydrator body; the bottom of the dehydrator body is provided with a filtered air buffer chamber with The breathing tube with the flange installed is inserted from the top of the rainproof cover from top to bottom through the silica gel particle layer and the activated carbon layer and inserted into the filtered air buffer chamber. The filtered air buffer chamber communicates with the outside of the equipment through a pipe. At the drain port of the stop valve, a heating element is arranged in the silica gel particle layer, and a control box is arranged under the filtered air buffer chamber. The invention can directly discharge the water vapor generated during the heating and dehydration process of the silica gel, and the heating and drying efficiency of the silica gel is high.

Description

technical field [0001] The invention relates to a moisture absorber, in particular to an upper air inlet and outlet type maintenance-free moisture absorber, a heating assembly and a control method thereof. Background technique [0002] Applied to transformers, high voltage reactors and large capacitors, air drying devices (moisture absorbers) for breathing ports generally use upper air intake and lower air outlet or upper air outlet and lower air intake structures, such as figure 1 and figure 2 shown. Traditional dehumidifiers need to replace silica gel particles regularly, which is time-consuming and labor-intensive, and the disposal of waste silica gel must be considered. Moreover, its working status cannot be automatically uploaded to the comprehensive monitoring system, and it is a kind of equipment that is facing elimination. In recent years, the maintenance-free dehumidifier that has emerged in recent years judges the degree of moisture in the silica gel by detectin...
