Capacity of oil-immersed transformer

To calculate the rated capacity of an oil-immersed transformer, you need to know the rated voltage and current of the original and payive parties. Their product is the rated capacity. Generally speaking, the design capacities of the original side and the paying side of the oil-immersed transformer are the same. If they are not the same, only the smaller side can be used as the rated capacity of the oil-immersed transformer. The product of the real-time voltage and the real-time current of the oil-immersed transformer is the real-time capacity. The capacity of a three-phase oil-immersed transformer is equal to 3 times the phase voltage multiplied by the phase current.

Each household in the community has 4 kilowatts, the number of households is N, and the simultaneous use coefficient is 0.7~0.8. Simplified estimation of oil-immersed transformer capacity = 4*N*(0.7~0.8). Oil-immersed transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. According to the purpose, it can be divided into: distribution oil-immersed transformer, fully sealed oil-immersed transformer, combined oil-immersed transformer, single-phase oil-immersed transformer, electric furnace oil-immersed transformer, rectifier oil-immersed transformer, etc. Oil-immersed transformer is a device that converts AC voltage, alternating current and impedance. When AC current flows through the primary coil, AC magnetic flux is generated in the iron core (or magnetic core), causing a voltage to be induced in the secondary coil ( or current). An oil-immersed transformer consists of an iron core (or magnetic core) and a coil. The coil has two or more windings. The winding connected to the power supply is called the primary coil, and the remaining windings are called secondary coils. The calculation methods of oil-immersed transformer capacity introduced by the transformer manufacturer and the various calculation methods of the capacity of common oil-immersed transformers are for your reference.
