A voltage regulator winding, also known as a stabilizing winding, is a special type of winding in a three-winding transformer that is designed to provide a stable output voltage. It is typically connected in parallel with the main winding and is used to regulate the voltage at the secondary side of the transformer.
The purpose of a voltage regulator winding is to compensate for voltage fluctuations caused by changes in the load or supply voltage. It achieves this by adjusting its own impedance in response to changes in the voltage, thereby maintaining a constant output voltage. This is particularly useful in applications where a stable voltage is required, such as in power distribution systems or in sensitive electronic equipment.
To understand how a voltage regulator winding works, let's consider an example. Imagine you have a three-winding transformer with a main winding, a voltage regulator winding, and a
tertiary winding. The main winding is connected to the primary side of the transformer and receives the supply voltage. The voltage regulator winding is connected in parallel with the main winding and the tertiary winding is connected to the secondary side of the transformer.
Now, let's say there is a sudden increase in the load connected to the secondary side of the transformer, causing a drop in the output voltage. The voltage regulator winding detects this drop in voltage and adjusts its impedance to compensate for the change. By doing so, it maintains a constant output voltage, ensuring that the load receives a stable voltage despite the increase in demand.
Similarly, if there is a sudden increase in the supply voltage, the voltage regulator winding will detect this and adjust its impedance accordingly to prevent the output voltage from exceeding the desired level. This ensures that the load is protected from overvoltage conditions.

稳压绕组，也称为调压绕组，是三绕组变压器中的一种特殊绕组，用于提供稳定的输出电压。它通常与主绕组并联连接，用于调节变压器的二次侧电压。 稳压绕组的作用是补偿由于负载或供电电压变化而引起的电压波动。它通过调整自身的阻抗来响应电压变化，从而保持恒定的输出电压。这在需要稳定电压的应用中特别有用，例如在电力配电系统或敏感的电子设备中。 为了理解稳压绕组的工作原理，让我们举个例子。想象一下，你有一个三绕组变压器，其中包括一个主绕组、一个稳压绕组和一个三次绕组。主绕组连接到变压器的一次侧，接收供电电压。稳压绕组与主绕组并联连接，三次绕组连接到变压器的二次侧。
现在，假设二次侧连接的负载突然增加，导致输出电压下降。稳压绕组会检测到电压下降，并调整阻抗以补偿这种变化。通过这样做，它保持恒定的输出电压，确保负载在需求增加的情况下仍然获得稳定的电压。
同样地，如果供电电压突然增加，稳压绕组将检测到这一情况，并相应地调整阻抗，以防止输出电压超过所需水平。这确保负载免受过电压的影响。
总之，稳压绕组在三绕组变压器中起到了稳定输出电压的关键作用，通过调节自身的阻抗来补偿电压波动，确保负载获得稳定的电压。这使得变压器在各种应用中能够提供可靠的电力供应。
