Hey there! As a supplier of fully sealed oil-immersed transformers, I've seen firsthand how load fluctuation can have a real impact on these crucial pieces of equipment. In this blog, I'm gonna break down what load fluctuation is, how it affects fully sealed oil-immersed transformers, and what you can do about it.
Let's start with the basics. Load fluctuation is when the electrical load on a transformer changes over time. This can happen for a bunch of reasons, like changes in the number of devices being used, shifts in industrial production, or even just the time of day. For example, during the day when businesses are open and people are using lots of electricity, the load on a transformer might be high. But at night when most things are turned off, the load drops.
So, how does this load fluctuation mess with a fully sealed oil-immersed transformer? Well, one of the biggest issues is temperature. When the load on a transformer increases, it generates more heat. And since these transformers are fully sealed, that heat can build up pretty quickly. High temperatures can cause all sorts of problems, like damaging the insulation inside the transformer. The insulation is super important because it keeps the electrical current flowing where it's supposed to go. If the insulation gets damaged, it can lead to short circuits or even a complete failure of the transformer.
Another problem is mechanical stress. When the load fluctuates, the transformer's components expand and contract. This constant movement can put a lot of stress on the internal parts of the transformer, like the windings and the core. Over time, this mechanical stress can cause cracks or other damage, which can also lead to performance issues or even a breakdown.
Load fluctuation can also affect the oil in the transformer. The oil in a fully sealed oil-immersed transformer serves several important functions, like cooling and insulating. But when the temperature changes due to load fluctuation, the oil can degrade more quickly. This can reduce its effectiveness as a coolant and insulator, which can further exacerbate the problems caused by load fluctuation.
Now, let's talk about some of the ways we can deal with these issues. One option is to use monitoring equipment. For example, a Single-phase Relay Protection Test Instrument can help us detect any abnormal electrical activity in the transformer. This can give us an early warning if there are any problems caused by load fluctuation.
A Partial Discharge Comprehensive Analyzer is another useful tool. It can detect partial discharges in the transformer, which are often a sign of insulation damage. By catching these issues early, we can take steps to prevent more serious problems from occurring.
And then there's the Transformer On-load Decomposition Switch Parameter Tester. This device can help us monitor the performance of the on-load tap changer, which is an important part of the transformer that helps regulate the voltage. By ensuring that the on-load tap changer is working properly, we can better manage the effects of load fluctuation.
In addition to using monitoring equipment, we can also design the transformer to be more resilient to load fluctuation. For example, we can use high-quality insulation materials that can withstand higher temperatures. We can also improve the cooling system to better dissipate the heat generated during periods of high load.
