The transformer brings great convenience to people in life and work, and solves the tripping or regional power outage caused by excessive voltage in people's daily life. The generation of the transformer can solve these hidden dangers.

Transformer is a very important electrical equipment in the power system. Whether it is working properly or not directly affects the safety of the power equipment. Different power grids have different requirements for transformers. Let me introduce the uses of various transformers in real life. .

The role of the transformer is multifaceted. It can not only increase the voltage to send electric energy to the electricity-consuming area, but also reduce the voltage to the voltage used at all levels to meet the demand for electricity. In short, both step-up and step-down must be completed by a transformer. In the process of transmitting electric energy in the power system, two parts of voltage and power will inevitably be lost. When the same power is delivered, the voltage loss is inversely proportional to the voltage, and the power loss is inversely proportional to the square of the voltage. The transformer is used to increase the voltage, and the power transmission loss is reduced.

So how should we choose a transformer in our lives? When the transformer is running at no load, a larger reactive power is required. These reactive power must be supplied by the power supply system. If the capacity of the transformer is too large, it will not only increase the initial investment, but also keep the transformer in no-load or light-load operation for a long time, which will increase the proportion of no-load loss, reduce the power factor, and increase the network loss. This operation is neither economical nor uneconomical. reasonable. If the transformer capacity is too small, the transformer will be overloaded for a long time and the equipment will be easily damaged. Therefore, the rated capacity of the transformer should be selected according to the needs of the electrical load, and should not be too large or too small.

This is the end of this issue of transformer knowledge, see you next time...
