Why does oil-immersed transformer leak oil
Causes of Oil Leakage in Oil-immersed Transformers 1. Welding quality The oil-immersed transformer shell is a combination of steel plate welding and connection. Longer welds and more welded joints have higher requirements for welding operations. Due to the influence of external environment, temperature, experience skills, welding materials, plates and other factors, the quality results after […]
Which points to be considered while installing transformers
Three Outdoor Installation Methods for Power Transformers There are three methods for outdoor installation of transformers, one is the pole tower type, the other is the platform type, and the third is the Pad-mounted type (including the pre-installed type). Pole Tower Type The pole tower type is to install the power transformer on the structure […]
Classification and function of transformer’s dielectric losses
Classification and function of transformer’s dielectric loss Dielectric loss of power transformer: 1. Dielectric loss is mainly caused by capacitive equipment; the host asked about the dielectric loss of the transformer, which should mainly refer to the magnetic dielectric loss. How to calculate the power losses of the transformer, the calculation method of the transformer iron […]
What is the alarm temperature of the dry-type transformer
What is The Alarm Temperature of The Dry-type Transformer? 1. At present, most dry-type transformers use H-class insulating materials, so generally the temperature of dry-type transformers should be below 180°C. 2. When class A insulating material is used, the maximum transformer temperature rise should be less than 60K when its limit working temperature is 105℃; when class […]
