Power Transformer Anti-short Circuit Measures

The operational stability of large transformers lies first in its construction and manufacturing technology level, and secondly, in the whole process of operation to carry out various experiments on machinery and equipment, and immediately grasp the working conditions of machinery and equipment. To master the reliability of the mechanical equipment of the transformer, the weak points can be improved according to the short circuit test to ensure that the compressive strength design scheme of the transformer structure is well understood.
Transformer manufacturers - standardize the design, pay attention to the axial pressing process of coil manufacturing.
When designing the scheme, in addition to considering the transformer to reduce wear and improve the level of the insulation layer, the manufacturer also needs to fully consider improving the impact toughness of the transformer and the working ability to resist common short circuit faults. At the level of manufacturing and processing technology, because many transformers have selected insulation layer pins, and high voltage and low voltage coils use the same pin, this kind of structure stipulates that there is a high level of manufacturing technology, to solve the protective layer pad to carry out dense solutions, after the coil production and processing also need to carry out constant current source drying of a separate coil, and accurately measure the height of the coil after shrinking.
Each coil of the same pin is adjusted to the same height after the above treatment process, and the working pressure required by the cooking oil pressure equipment is used to increase the required working pressure of the coil during the assembly process, and then the height specified by the design scheme and processing technology is achieved. In the total installation, in addition to paying attention to the pressing condition of the pressure coil, it is also necessary to pay attention to the manipulation of the pressing condition of the bottom pressure coil.
