1 IntroductionIn the process of electric energy transmission and distribution, power transformers are the core of energy conversion and transmission. They are the only way for all walks of life in the national economy and thousands of households to source energy. They are the most important and crit
1. Abnormal sound: The transformer emits a uniform and rhythmic "buzzing" sound during normal operation. If other abnormal sounds occur, it is abnormal sound. The main reasons are as follows:① When a large-capacity power equipment is started, the load suddenly increases and the transforme
The technology of live cleaning and maintenance of electric power and electrical equipment is generally a technology for cleaning power and electrical equipment that does not have power outages or has periodic power outages. Cleaning is carried out by professional cleaning personnel using profession
Transformers are one of the key electrical equipment in power distribution stations. Oil-immersed transformers are widely used because they have good dielectric strength, strong heat transfer performance and low construction costs. They can solve the problem of heat pipe heat dissipation in large sp
■ Advantages and disadvantages of dry-type transformers and oil-immersed transformersIn terms of price, dry change is more expensive than oil change.In terms of capacity, large-capacity oils produce more oil than dry ones.Dry inverters need to be used in complex buildings (basements, floors, roofs,
