In recent years, with the rapid development of the urban rail transit scale in China, the power and lighting load of subways has increased rapidly, and the problem of electric energy consumed by the self - losses of distribution transformers has become increasingly prominent. Against the backdrop of the country's advocacy for energy conservation and environmental protection, amorphous alloy core transformers, which use amorphous alloy strips with excellent magnetic conductivity as the magnetic -

With the continuous acceleration of the urban-rural integration process, the construction quality of the rural power grid is directly related to the vital interests of the general public and has an impact on the economic development of the entire rural area. Currently, 10kV distribution transformers and box transformers are the most widely used power equipment in the rural power distribution system, and they also require the most operation and maintenance. They are key control objects for ensuri

Introduction to Fuses of American-style Box TransformersAmerican-style box transformers generally use a combination of plug-in fuses and backup protection fuses in series to provide protection. The protection principle is advanced and reliable, and the operation is simple. The backup protection fuse is an oil-immersed current-limiting fuse, usually installed inside the box transformer. It will operate only when a fault occurs inside the box transformer, and it is used to protect the high-voltage

Fault Causes of Distribution TransformersFaults Caused by Temperature RiseImpact on Metal MaterialsWhen a transformer is in operation, if the current is too large, causing the customer load to exceed the rated capacity of the transformer, the temperature of the transformer will rise, which in turn softens the metal materials and significantly reduces their mechanical strength. Take copper as an example. If it is exposed to a high - temperature environment above 200 °C for a long time, its me
