Cut to length line supplier from China: What does the rated value on the nameplate of the transformer mean? The rated value on the transformer nameplate refers to some important electrical parameters and performance indicators of the transformer. Usually includes the following aspects: Rated capacity: The rated capacity of a transformer refers to the maximum load electric power that the transformer can continuously supply. For example, a 10MVA transformer means that the transformer’s maximum load can reach 10 megawatts. Rated voltage: The rated voltage of the transformer refers to the design voltage of the transformer. For example, a 220kV/110kV transformer means that the input voltage of the transformer is 220 kV and the output voltage is 110 kV. Rated frequency: The rated frequency of a transformer refers to the power frequency for which the transformer is designed. In China, the power frequency is usually 50Hz. Short-time withstand current: The short-time withstand current of a transformer refers to the maximum current value that the transformer can withstand in a short period of time. For example, the short-term withstand current of a transformer is 50kA, which means that the transformer can withstand an instantaneous current of up to 50 kA. See extra details at transformer coil.
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.

Epoxy resin dry transformer has the characteristics of good electrical performance, strong resistance to lightning impact, strong resistance to short circuit, small size and light weight. Temperature display controller can be installed to display and control the operating temperature of the transformer winding to ensure the normal service life of the transformer.
The cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When air cooled naturally, the transformer can run continuously for a long time under rated capacity. When forced air cooling, transformer output capacity can be increased by 50%. Suitable for intermittent overload operation, or emergency overload operation; Because the load loss and impedance voltage increase greatly during overload, it is in non-economic operation state, so it should not be in continuous overload operation for a long time.Welcome to inquiry price for dry type substation transformer.

As a result of mutual inductance, a transformer produces a transformed voltage or current when the magnetic flux produced by one winding (primary winding) links with another winding (secondary winding). There is a magnetic coupling between these two windings, and they are electrically isolated. In addition, magnetic reluctance is also known as opposition to magnetic flux flow. If, for example, the magnetic flux produced by a primary winding passes through air or any nonferrous material in order to reach a secondary winding in a transformer, it would result in a reduction in magnetic flux. Due to the high reluctance of air or nonferrous materials, it will reduce magnetic flux. See more details at https://www.canwindg.com/
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.
To accommodate the needs of grid voltage changes, the high-voltage side of the transformer has taps, which can be adjusted by adjusting the number of turns in the high-voltage winding to regulate the output voltage on the low-voltage side. Rated current (A): The current allowed to pass through the transformer for a long time under rated capacity. No-load loss (kW): The active power drawn when a rated voltage at rated frequency is applied to one winding terminal and the remaining windings are open circuit.It is related to the performance and manufacturing process of the core silicon steel sheet, as well as the applied voltage.
In terms of productivity, poor PQ can cause unscheduled downtime due to equipment malfunctions or system failures. This unpredictability can significantly disrupt operations, leading to lower productivity levels and potential revenue losses. Moreover, poor PQ can lead to diminished energy efficiency. Transformers operating under poor power quality conditions often require more power to function, leading to increased energy consumption and higher operating costs. The excess power demand could also strain the electrical grid, leading to further inefficiencies and disruptions. Additionally, the costs associated with repairing or replacing damaged equipment due to poor power quality can be substantial. There are also indirect costs to consider, such as those associated with investigation and troubleshooting of power quality issues.
