121kv/50000 KVA On-load Voltage-changing Power Transformer (SZ11)

Product Introduction

121kV/50000kVA on-load voltage-regulating power transformer is a transformer that can complete tap voltage switching during load operation. It is mainly used to adjust the tap position of the transformer to maintain voltage stability when the system voltage fluctuates or the user load changes, thereby ensuring the power supply quality.

Application scenarios and advantages
This transformer is suitable for occasions where voltage needs to be adjusted frequently to adapt to different load conditions, especially in power systems. When the system voltage fluctuates or the user load changes, the tap position of the transformer can be adjusted to maintain voltage stability, thereby ensuring the power supply quality. In addition, on-load voltage-regulating transformers can effectively reduce power outage time and improve power supply reliability.

What are the components of the transformer?
The core components of a transformer include the iron core and the coil. In addition, there are other components such as the oil tank, oil pillow, insulating bushing and tap changer. The oil tank is used to contain transformer oil and insulating materials; the oil pillow is used to store extra transformer oil and help dissipate heat; the insulating bushing is used to protect the coil and ensure safety; and the tap changer is used to adjust the transformer's turns ratio and output voltage.
