What is a 500 kva dry-type step-down transformer?

500 kva dry-type step-down transformer is a power equipment that is mainly used to convert high-voltage electric energy into low-voltage electric energy. Its rated capacity is 500 kva. It is light in weight and easy to install and maintain. Can be seen in various places

500 kva dry-type step-down transformer Specific uses
500kva transformer is suitable for various power supply places, mainly used in subways, high-rise buildings, airports, stations, docks, and due to its dry structure, it is particularly suitable for places with high fire protection requirements, such as shopping malls, hospitals, data centers, etc.

500 kva dry-type step-down transformer Technical parameters and performance characteristics
Voltage ratio: The common voltage ratio is 0.38/6KV and 1.14KV, that is, the input voltage is 0.38KV (380V), and the output voltage is 6KV (6000V) and 1.14KV (1140V)

Efficiency: The efficiency of some three-phase dry-type transformers can reach 98%, which means that there is less energy loss during the energy conversion process

Insulation resistance: The insulation resistance is required to be ≥50MΩ to ensure safe and reliable operation

Electrical strength: It can withstand the industrial frequency sinusoidal voltage of 3KV for 1 minute without breakdown and flashover

Maintenance and maintenance
Dry-type transformers do not need to regularly check and maintain the oil status like oil-immersed transformers, reducing maintenance workload and costs.

What should be paid attention to during the transportation of dry-type 500kVA transformers

500 kva dry-type step-down transformer are large in size and heavy in weight. During transportation, cranes, forklifts and other tools can be selected to ensure that the transformer is protected from vibration and impact and to protect the stability of the transformer

‌In addition, the insulation of the transformer needs to be protected during transportation: avoid moisture, water and other external factors that may cause insulation rupture. It may affect the use of the transformer, especially in rainy days or humid environments. Rainproof measures should be taken to protect the transformer.
