Hey there! As a supplier of Pad Mounted Transformers, I often get asked about the oil used in these transformers and what it actually does. So, I thought I'd break it down for you in this blog post.
What Kind of Oil is Used in Pad Mounted Transformers?
Most Pad Mounted Transformers use mineral oil. This oil is derived from crude oil and has been a staple in the transformer industry for a long time. Mineral oil is a great choice because it has excellent electrical insulating properties. It can prevent electrical currents from leaking out and causing short - circuits or other electrical issues.
Another type of oil that's becoming more popular is synthetic oil. Synthetic oils are man - made and have some advantages over mineral oil. For example, they are more fire - resistant. In areas where there's a higher risk of fire, using a transformer with synthetic oil can be a smart move. Some synthetic oils also have better environmental profiles, as they are biodegradable.
There's also a type of oil called silicone oil. Silicone oil has a very wide operating temperature range. It can work well in extremely cold or hot environments. This makes it suitable for Pad Mounted Transformers that are installed in places with harsh weather conditions, like deserts or high - altitude areas.
The Functions of the Oil in Pad Mounted Transformers
1. Electrical Insulation
The primary function of the oil in a Pad Mounted Transformer is electrical insulation. Inside a transformer, there are coils of wire that carry high - voltage electricity. The oil fills the space between these coils and other components. It has a high dielectric strength, which means it can withstand high voltages without breaking down and allowing current to flow where it shouldn't. This insulation is crucial for the safe and efficient operation of the transformer. Without proper insulation, the electrical currents could cause arcing, which can damage the transformer and pose a safety hazard.
2. Cooling
Transformers generate a lot of heat when they're operating. The electrical resistance in the coils and other components causes energy to be converted into heat. If this heat isn't removed, it can cause the transformer to overheat and eventually fail. The oil in the transformer acts as a coolant. It absorbs the heat from the hot components and then transfers it to the walls of the transformer tank. From there, the heat is dissipated into the surrounding environment.
The oil circulates within the transformer. As it gets heated up near the hot components, it rises to the top of the tank. Cooler oil then moves in to take its place, creating a natural convection current. This continuous circulation helps to keep the temperature of the transformer within a safe operating range.
3. Arc Quenching
In some situations, electrical arcs can occur inside the transformer. This can happen when there's a sudden change in the electrical load or a fault in the system. The oil in the transformer plays a role in quenching these arcs. When an arc forms, the high - energy arc heats up the oil around it. The oil then vaporizes, creating a gas bubble. This gas bubble has a high dielectric strength and can stop the arc from continuing. It's like putting out a fire by smothering it. This arc - quenching ability helps to protect the transformer from damage caused by arcing.
