In modern power system, voltage stability and reliability are very important. In order to ensure the safe transmission and efficient use of power, On-load Tap Changer Transformer comes into being. It is a special type of transformer that can automatically or manually adjust the output voltage in the case of load operation to adapt to different load requirements and grid conditions. Now we will discuss in detail the working principle, main composition, application field and advantages of on-load voltage regulation transformer.

First, the working principle of on-load voltage regulating transformer

The core function of on-load regulator transformer is to regulate voltage. Its working principle is based on the basic principle of the transformer, by changing the tap position of the transformer to achieve voltage regulation. The voltage ratio between the primary and secondary windings of the transformer is determined by the tap position. When the load changes, the transformer will automatically adjust the tap according to the actual demand of the power grid to maintain the stability of the output voltage.

On-load regulator transformers are usually equipped with regulator devices that can be adjusted while the load is running. This adjustment is different from the off-load Tap Changer Transformer, which can only be adjusted when the transformer is powered Off. Through the on-load regulator, the power system can maintain voltage stability under different load conditions to avoid equipment damage and power supply interruption caused by voltage fluctuations.

Second, the main composition of the on-load voltage regulator transformer

The on-load regulating transformer is mainly composed of the following parts:

1. Transformer body: including iron core, winding and insulation materials. The core is used to direct the magnetic flux, and the winding is used to transmit electrical energy.

2. Voltage regulator: This is the core part of the on-load voltage regulator transformer, which is usually composed of multiple taps, switches and control systems. The voltage regulator can monitor the output voltage in real time and automatically adjust the tap position according to the set value.

3. Control system: Modern on-load voltage regulating transformers are usually equipped with intelligent control systems, which can automatically adjust the voltage to ensure the stability of the power grid by monitoring the real-time data of the power grid.

4. Protection device: including overload protection, short circuit protection and overvoltage protection, etc., to ensure that the transformer can operate safely under abnormal conditions.

Third, the application field of on-load voltage regulator transformer

On-load regulation transformers are widely used in various fields of power systems, especially in the following aspects:

1. Power transmission: In long-distance power transmission, the voltage may fluctuate significantly due to the influence of line impedance. The on-load voltage regulator can effectively regulate the voltage to ensure the stability of the power during transmission.

2. Power distribution system: In urban or industrial power distribution networks, on-load voltage regulating transformers can automatically adjust the voltage according to the change of load to ensure the normal operation of user equipment.

3. Renewable energy: With the continuous development of renewable energy sources, such as wind and solar, the load on the grid changes more frequently. The on-load voltage regulating transformer can quickly respond to the changes of the power grid to ensure the stable supply of power.

Fourth, the advantages of load regulating transformers

Compared with traditional no-load regulating transformers, on-load regulating transformers have the following obvious advantages:

1. Real-time regulation: The on-load voltage regulator can adjust the voltage in real time when the load is running to avoid damage to the equipment caused by voltage fluctuations.

2. Improve the reliability of power supply: By automatically adjusting the voltage, the on-load voltage regulator can improve the reliability of power supply of the power system and reduce the occurrence of power outage accidents.

3. Strong adaptability: Whether it is urban distribution network or industrial electricity, on-load voltage regulation transformers can be adjusted according to actual needs to adapt to different grid conditions.

4. Energy saving and consumption reduction: By optimizing voltage, on-load voltage regulator can reduce power loss and improve the overall efficiency of the power system.

On-load voltage regulating transformer plays an important role in modern power system. It not only improves the stability and reliability of power, but also provides a guarantee for the efficient use of power. With the increasing demand for power and the increasing complexity of the power grid, the application of on-load voltage regulation transformers will become more and more extensive and become an indispensable part of the power industry.

Through the in-depth understanding of on-load regulator transformers, we can better realize the complexity of power system and its importance to modern society. In the future, with the continuous progress of science and technology, the technology of on-load voltage regulator will also continue to develop, providing more powerful support for the safe and efficient operation of the power system.
