Transformer operation and maintenance
Transformer Operating TemperatureDuring operation, transformers generate copper losses and iron losses, both of which are converted into heat, causing the transformer’s temperature to rise. Most transformers in China use Class A insulation. Due to heat transfer characteristics, significant temperature differences exist between different components during operation: winding temperature is the highest, followed by the core, and then the temperature of the insulating oil (with upper-layer oil being

What Is An Inverter-integrated Transformer?
What Is An Inverter-integrated Transformer?
An inverter-integrated transformer is a power conversion device that combines the functions of an inverter and a transformer into a single unit. Widely utilized in renewable energy systems such as solar photovoltaic (PV) and wind power generation, its primary role is to convert direct current (DC) to alternating current (AC) while adjusting voltage levels (stepping up or down) via the transformer, ensuring compatibility with grid requirements or specific load demands.1. Basic Functions and Opera

Estimation of capacitive current
Estimation of capacitive current
The capacitive current is mainly determined by the length of the feeder, the cross-sectional area of the conductor, the dielectric constant, the height above the ground, and the rated voltage. The specific estimation methods are as follows:Estimation of capacitive current of overhead lines: For overhead lines of 3 - 35 kV, the capacitance per phase to ground is usually 5000 - 6000 pF/km. Based on this, the value of the single-phase grounding capacitive current per kilometer for lines of differen

What are the basic knowledge points about transformer bushings?
1. Functions of Transformer BushingsThe core function of transformer bushings is to lead the coil leads out to the external environment. They serve both as insulating components between the leads and the oil tank and as fixing devices for the leads.During the operation of a transformer, bushings continuously carry load currents and, in the event of an external short circuit, withstand short-circuit currents. Therefore, transformer bushings must meet the following requirements:Possess specified e
