The advantages and disadvantages of the circulation method are opposite to the "moving method". It connects the transformer oil to the oil filter from the lower part of the oil tank, and connects the oil return pipe to the upper part of the ...

Transformers have a wide variety and are widely used. Today, let Alisa, the sales manager of hengfengyou electric, introduce the difference between autotransformer and ordinary transformer in power transformer:...

The oil drain in the cooling machine and equipment is forced circulation, at least in the main winding resistance, it is forced to correctly guide the circulation; The common cooling methods of power engineering transformers are generally di...

Box type transformer is a general term for the transformer system installed in the box （as protection）， which is divided into three parts: ① high voltage switch control room; ② Transformer room; ③ Low voltage switch control room...

By analyzing the influence trend of these influencing factors on the withstand voltage strength of transformer oil, it shows that the higher the voltage level of transformer, the stricter the control requirements for water content, gas conte...

Oil immersed transformer is called insulating oil. Its function is to prevent breakdown. If the high-voltage end of the transformer is not insulated, corona or breakdown accidents will occur, causing losses to staff and equipment. Transform...

Common fault causes and solutions of transformer: it is mainly due to poor welding quality, false welding, desoldering, pinhole, sand hole and other defects in the weld, and the power transformer is covered with solder and paint when leaving...

Oil immersed transformer explosion accidents occur frequently. Because the explosion process of oil immersed transformer is a relatively slow development process, once the explosion occurs, there will be casualties and huge economic losses, ...
