Kerosene gas phase drying equipment gas phase drying can reduce energy loss:

The analysis and calculation show that the new gas-phase drying method has the following advantages: the production efficiency is improved, and the time of treating products with gas-phase drying technology is more than 1p3 shorter than that with hot air circulation technology. Although the transformer body needs to be dried, the time is very short. In this way, the time of using gas-phase drying technology to treat the transformer is half shorter than that of using hot air circulation to treat the transformer.

Transformer gas-phase drying technology is a new method applied to the vacuum treatment of transformer. This paper mainly compares the advantages and disadvantages of two drying methods used in transformer, and discusses the advantages of gas-phase drying technology used in transformer.

The drying process of insulating materials is the diffusion of water vapor molecules from insulating materials to the surrounding space. The driving force driving the water to move to the outside of the insulating material is mainly the water vapor partial pressure difference between the inside of the insulating material and the surrounding old space. Therefore, the larger the pressure difference, the faster the drying speed. Two interpretation diameters are added to increase the temperature of the insulating material, that is, to heat the insulating material; It is to reduce the ambient pressure and improve the drying method from these two 17 sides, which is the so-called thermal vacuum drying method. The hot air circulation is related to the air. It is all this ten drying method. The hot air circulation drying method is a drying method with air as the heat carrying medium, that is, the heating method of hot air circulation under atmospheric pressure, and the temperature is controlled within 1. With this method, the processing time of the product is long, so the manufacturing period of the product is prolonged.

The gas-phase drying method uses coal steam as the heat carrier, which can be added in vacuum, increase the heating temperature from 1 to 130, and increase the diffusion coefficient of water in insulation by times, so as to greatly shorten the processing time of products. The kerosene gas-phase drying technology has been used since the 1960s, and now it has been widely used in the bait air drying treatment of ten large transformers. Its treatment effect has been proved to be an advanced drying treatment method. The insulation of high-voltage current transformer above 0 times is relatively thick, and there are main screen and end screen made of aluminum foil or semiconductor paper between layers. Its insulation water outlet is much more difficult than that of transformer. At present, the vacuum drying method of hot air circulation is widely used for the insulation of high-voltage current transformer. Its technological process is body treatment 1! The finished product of furnace assembly is processed, that is, the assembled transformer body is in the vacuum with hot air circulation, enters the hall for insulation and drying treatment, and is dried thoroughly. When the residual water in the factory is less than the allowable value of 0.10.5, the transformer body is out of the furnace for assembly.
