Top dry type transformers supplier: Power quality plays a crucial role in the performance and longevity of distribution transformer substation. Poor power quality can lead to increased losses, reduced efficiency, and shorter equipment lifespan. Therefore, effective strategies for power quality management are indispensable for the optimal operation of distribution transformers. Harmonic currents, particularly those of higher frequencies, can significantly affect the performance of transformers. These currents are produced by non-linear loads such as computers, variable speed drives, and certain types of lighting systems, causing distortions in the sinusoidal waveform of the electrical supply.

Why does the current source inverter need a larger transformer capacity? Current source inverter is a common type of inverter. Its control method adopts current loop control, which has the advantages of high precision and strong adaptability, and is widely used in industrial production. Due to the working characteristics of the current source inverter, a large transformer capacity is required for the following reasons: The current source inverter adopts the intermediate inductance: the current source inverter adopts the intermediate inductor, which can realize the phase difference between the output voltage and the current, so as to realize the frequency conversion control. However, since the intermediate inductor needs to withstand large current and voltage, it is necessary to select a transformer with a larger capacity to ensure the normal operation of the inductor.

The main pillar of the smart grid is the smart substation, which is not only an important hub for power transmission and distribution, but also directly affects the operational and monitoring capabilities of the smart grid through its operational safety and stability. Through the network, information can be exchanged, and the transformer can share information with the process layer and the station control layer. On the premise of ensuring product performance, the integration of monitoring, control, measurement, protection, and metering is designed to achieve the integration of transformer components with actuators, sensors, and transformers.
Impedance voltage (%): Short-circuit the secondary winding of the transformer and slowly increase the voltage on the primary winding. When the short-circuit current of the secondary winding equals the rated value, the voltage applied on the primary side is the impedance voltage. It is usually expressed as a percentage of the rated voltage. Phase number and frequency: Three-phase is represented by S, and single-phase is represented by D. The frequency f of China’s national standard is 50Hz.There are countries abroad with 60Hz (such as the United States).I. Temperature rise and cooling: The difference between the temperature of the transformer winding or upper oil layer and the temperature of the surrounding environment is called the temperature rise of the winding or upper oil layer. The limit value of the temperature rise of the oil-immersed transformer winding is 65K, and the temperature rise of the oil surface is 55K.There are also various cooling methods: oil-immersed self-cooling, forced air cooling, water cooling, tube type, sheet type, etc.
Insulation level: The insulation level of a transformer refers to the insulation performance of the transformer at the time of design. For example, a 220kV transformer means that the designed insulation voltage of the transformer is 220 kV. Cooling method: The cooling method of the transformer refers to the heat dissipation method of the transformer. For example, transformers can dissipate heat through natural cooling, forced air cooling, or forced water cooling. To sum up, the rated value on the transformer nameplate refers to some important electrical parameters and performance indicators of the transformer, which is of great significance for the selection, installation and operation of the transformer.
