Introduction

Oil-immersed split-winding transformers have become increasingly important in modern electrical distribution systems. They are known for their efficiency, reliability, and adaptability to various load conditions. This article will provide an in-depth analysis of their benefits, delve into the specific solutions offered by HOLEEP, a prominent company in this domain, and cite authoritative references to support the information presented.

Benefits of Oil-immersed Split-winding Transformers

Oil-immersed split-winding transformers offer numerous advantages for electrical power distribution and utilization:

1. Improved Efficiency

Split-winding transformers are designed to reduce losses and enhance efficiency. Typically, these transformers can achieve efficiencies greater than 98%, with energy losses minimized to below 2% under standard operating conditions. Their design optimizes the magnetic circuit, contributing to lower no-load losses.

2. Enhanced Load Sharing

This configuration enhances load sharing capability, enabling transformers to handle peak loads without excessive temperature rise. The split-winding design ensures equal distribution of the load across all windings, promoting uniform temperature distribution and prolonging the transformer’s lifecycle.

3. Robust Thermal Performance

The oil-immersed aspect provides superior cooling, maintaining winding temperatures within thermal limits even under high load conditions. The use of oil as a cooling medium allows these transformers to maintain operational integrity at ambient temperatures up to 40°C with minimal degradation, improving transformer reliability.

4. Reduced Fault Levels

Split-winding transformers limit fault levels by effectively splitting the winding into two or more sections, which can be beneficial in complex power systems where reduced fault levels are required to protect sensitive equipment.

5. Cost-effectiveness

The ability to handle variable loads without additional equipment reduces the need for expensive infrastructure upgrades. Over the lifecycle of the transformer, operational savings and reduced maintenance costs can lead to significant financial benefits.
