How does the special transformer get wet?

Electric furnace transformers are used in the metallurgical industry to smelt high-quality alloy steels, ferroalloys, etc.; in the chemical industry, they are used to produce yellow phosphorus, calcium carbide, synthetic resins, etc.; in the machinery industry, electric furnace transformers are used for smelting cast steel and cast iron, etc. For transformer equipment, it is necessary to avoid the intrusion of moisture and moisture,Special transformerIt is required to have better insulation for the transformer, and pay attention to the use and protection methods in the later period. So how do special transformers get wet and how to deal with them?

1. After the transformer is purchased, the power supply bureau should be asked to do an account test.

2. When installing the transformer, it is strictly forbidden to use aluminum stranded wire, aluminum row, etc. to connect with the copper guide rod of the transformer to avoid corrosion of the guide rod.

3. Immediately install a moisture absorber. Transformers with a capacity of 100 kVA and above are equipped with a moisture absorber. Once the transformer is transported to the site, a moisture absorber should be installed to prevent the internal body from getting wet.

4. When ordering, it should be noted that the storage time of the transformer before power transmission should be minimized. After the transformer is manufactured, it is very easy to get wet during storage. The longer the storage time, the more serious the moisture will be. Therefore, the plan should be arranged and the storage time should be shortened as much as possible.

5. Small transformers with a capacity of 100 kVA and below, no moisture absorber equipment. The oil in the oil pillow is easily damp, and the oil pillow accumulates water. It will be stored for more than 6 months after no power transmission, or more than one month after being put into operation. The oil in the transformer oil pillow has been seriously damped. If you want to carry out lifting and transportation, repair and refueling, oil valve discharge, hanging core, etc., you should first use the oil drain plug under the oil pillow to drain the oil in the oil pillow. Drain it, wipe it with a dry cloth, and seal it well to prevent the dirty oil in the oil pillow from entering the oil tank.

6. During the operation of the transformer, always pay attention to the changes of oil level, oil temperature, voltage and current. If there is any abnormal situation, it should be analyzed and dealt with in time.

7. Supervise the silica gel in the dehumidifier. It should be replaced immediately after getting wet. The silica gel in the dehumidifier has the effect of absorbing moisture and protecting the transformer. After the moisture is fully absorbed, the color of the silica gel changes, and a new dry silica gel needs to be replaced.
