Pole Mounted Transformer Key Craft
- Magnetic Circuit Design:The shape, size, hysteresis characteristics, and eddy - current
loss of the iron core are crucial considerations. An optimized
magnetic circuit design ensures efficient energy transfer and
minimizes power losses, enhancing the overall performance of the
transformer.
- Winding Design:During the design phase, multiple elements, including the number of
turns, wire material, interlayer insulation, and wiring
configuration, must be carefully evaluated. A meticulously planned
winding design significantly improves the transformer's load -
bearing capacity and operational reliability, enabling it to
perform stably under various electrical loads.
- Insulation Material Selection:Selecting appropriate insulation materials is a fundamental
requirement for ensuring the safety and extended lifespan of the
transformer. Insulation materials with superior insulation
properties, high - temperature resistance, arc - resistance, and
moisture - resistance are essential to prevent electrical
breakdowns and safeguard the transformer's internal components.
- Vacuum Oil Filling:Vacuum oil filling is commonly employed in single - phase pole -
mounted transformers. This process involves evacuating the
transformer core under vacuum conditions, injecting high - quality
insulating oil, removing any trapped air bubbles, and then
hermetically sealing the unit. Vacuum oil filling effectively
improves the transformer's insulation performance and thermal
stability, thereby extending its service life.
- Heat Treatment:Heat treatment is a critical process that can enhance the
mechanical properties and structural strength of transformers. By
altering the material's microstructure, heat treatment increases
hardness and wear - resistance, while simultaneously reducing
internal stress and minimizing deformation, ensuring the
transformer's durability and long - term reliable operation.
