The length of time a transformer can operate normally under rated voltage and rated load is called the service life of the transformer. Materials used in transformer manufacturing fall into two main categories: metallic materials and insulating materials. Metallic materials generally can withstand relatively high temperatures without damage, but insulating materials will rapidly age and degrade when the temperature exceeds a certain value. Therefore, temperature is one of the main factors affect

1. About the Hydraulic TransformerA hydraulic system typically consists of a hydraulic power source (pump), actuators (hydraulic cylinder or motor), control components, and auxiliary parts. However, one critical component is notably missing—the hydraulic transformer. Hydraulic transmission is often compared to electrical transmission, and hydraulic control systems to electrical control systems, due to their strong similarities and corresponding functional components and parameters. Can we imagin

During operation, transformers may generate magnetizing inrush currents due to various factors. These inrush currents not only affect the normal operation of the transformer but may also compromise the stability of the power system. Therefore, accurately identifying transformer magnetizing inrush current is crucial for effectively suppressing such inrush.Next, let's explore how wavelet theory is applied in analyzing transformer magnetizing inrush current. Wavelet analysis is a method that provid

Application of Vegetable Oil in High-Voltage Power TransformersVegetable oil transformers are more environmentally friendly, safer, and longer-lasting compared to mineral oil transformers. As a result, their use is increasing both domestically and internationally. It is estimated that the number of vegetable oil transformers worldwide has already exceeded 2 million.Among these 2 million units, the vast majority are low-voltage distribution transformers. In China, only one vegetable oil transform

With the rapid development of China's economy, the power industry has also gradually expanded in scale, increasing the requirements for both the installed capacity and the single-unit capacity of power transformers. This article provides a brief introduction to four aspects: transformer construction, transformer lightning protection, transformer faults, and transformer noise.A transformer is a commonly used electrical device capable of converting AC electrical energy. It can transform one form o

Why Silicon Steel Sheets Are Used in Transformer Cores – Reducing Eddy Current LossWhy reduce the other type of iron loss—eddy current loss?When a transformer operates, alternating current flows through its windings, producing a correspondingly alternating magnetic flux. This changing flux induces currents within the iron core. These induced currents circulate in planes perpendicular to the direction of the magnetic flux, forming closed loops—hence they are called eddy currents. Eddy current los
