In the use of baoding in the process of dry type transformer, it is easy to find, the fault is relatively common, often at this time of the electrical workers immediately take measures for processing, and in the process there are some items that need our attention, below, dry type transformer manufacturers will handle baoding dry type transformer fault is given some matters needing attention in the introduction.

 

1. Insulation should be guaranteed when replacing insulation parts.

 

The insulation parts that are replaced should be tested for their performance and can be used in accordance with the requirements. Special attention should be given to the insulation of the block. Block before installation should be under 80 ℃ heat transformer oil impregnated in a period of time, to ensure that the insulation of the block.

 

2. Transformer insulation test shall be carried out 24 hours after the transformer is still in the oil.

 

Because some of the damp insulation is immersed in hot oil for a long time, the water will spread to the surface of the insulation. If the oil is injected, the test will not be able to be checked out. Therefore, the insulation test should be reliable after 24 hours after the transformer is stopped.

 

3. The core should be paid attention to its sharp Angle.

 

Feng in the back yoke, attention should be paid to baoding wedge Angle of dry type transformer iron core chip, and timely measurement insulation oil, especially pay attention to the oil duct in chip corners, to prevent the chip core multipoint earthing lap.

 

4. Replace the winding materials with strong anti-short-circuit ability and improve the structure.

 

The mechanical strength of transformer windings is determined by the following two aspects: first, the winding mechanical strength determined by the factors of the winding's own structure; The second is the mechanical strength of the inner diameter side of the winding and the axial compression structure of the winding shaft and the drawing plate and the clamping process. At present, most of the transformer tank manufacturers half hard copper wire or self-adhesive transposed conductor is used to improve the winding itself anti-short circuit ability, amorphous alloy transformer used better quality cardboard tube or increase the number of stay to improve the ability of winding by the radial force, and USES the board or the spring compression screws to improve the ability of winding by the axial force.

 

5. The drying of the transformer.

 

Due to the short circuit shock of the transformer, it usually takes a long time to repair. In order to prevent the transformer from dampness, two measures can be taken:

 

A transformer buckle cover before the work every day, using vacuum pump to vacuum transformer, transformer with smoke free water on the surface of the body, the second day starts, using dry nitrogen or air lift vacuum drying, generally in transformer maintenance after hot oil circulation 24 hours can be directly put into operation;

 

Second, every day after work, waterproof measures for transformer, all the work completed, the amorphous alloy transformer adopt hot oil spray drying method, this method usually need to 7 to 10 days.

 

Therefore, baoding dry transformer should be used cautiously, once the baoding dry transformer has a short circuit fault, the attention should not be ignored in the process of processing.
