S13 500KVA 10/0.4KV Oil - Immersed Transformer
The S13 500KVA 10/0.4KV oil - immersed transformer is a high - performance electrical device widely used in power distribution systems. This type of transformer, with the core keyword "500KVA oil transformer", plays a crucial role in stepping down the high - voltage electricity from the power grid to a suitable voltage level for end - users.
1. Design and Structure
- The S13 series 500KVA oil - immersed transformer features a well - engineered design. Its core is made of high - quality cold - rolled grain - oriented silicon steel sheets. These sheets are carefully stacked and annealed to reduce core losses, which not only improves the energy efficiency of the transformer but also reduces heat generation during operation.
- The transformer tank is made of high - strength steel plates. It is designed to be hermetically sealed to prevent oil leakage and protect the internal components from external environmental factors such as dust, moisture, and corrosive substances. The tank is also equipped with heat - dissipating radiators on the outside, which effectively transfer the heat generated inside the transformer to the surrounding environment, ensuring stable operation.
2. Electrical Performance
- Rated Capacity: As the name suggests, the rated capacity of this transformer is 500KVA. This means it can handle a relatively large amount of electrical power, making it suitable for medium - sized industrial and commercial applications.
- Voltage Ratio: The transformer has a voltage ratio of 10/0.4KV. It can step down the high - voltage input of 10KV from the power grid to a low - voltage output of 0.4KV, which is commonly used in low - voltage power distribution systems for lighting, motors, and other electrical equipment.
- Efficiency: Thanks to the advanced design and high - quality materials, the S13 500KVA oil - immersed transformer has a high efficiency. It can convert electrical energy with minimal losses, which is in line with the current trend of energy conservation and environmental protection.

4. Safety and Protection
- The S13 500KVA oil - immersed transformer is equipped with a variety of safety protection devices. For example, it has a temperature controller that can monitor the temperature of the oil and windings in real - time. When the temperature exceeds the set value, an alarm signal will be issued, and in severe cases, the transformer can be automatically shut down to prevent damage.
- There is also an oil - level indicator to monitor the oil level in the tank. If the oil level is too low, it may indicate a potential oil leakage problem, and timely maintenance can be carried out.
In conclusion, the S13 500KVA 10/0.4KV oil - immersed transformer, as a typical 500KVA oil transformer, is a reliable and efficient electrical equipment that meets the needs of modern power distribution systems with its excellent performance, advanced design, and strict compliance with national standards.
