Scb11 33kv 35kv 2500kva Dry Type Transformer

The scb11 33kv 35kv 2500kva dry type transformer produced by Wenzhou Xifa Electrical Equipment Co., Ltd., are not only oil free, but all their components are solid state, with no flash point and no need for bushings, thereby eliminating the major risks of fire and oil leakage. Furthermore, most of the insulating materials used in scb11 33kv 35kv 2500kva dry type transformer transformers are easy to recycle, making them environmentally friendly as well.

The safe operation and service life of a scb11 33kv 35kv 2500kva dry type transformer largely depend on the reliability of the transformer winding insulation. Winding temperatures exceeding the insulation's tolerance temperature can damage the insulation, which is one of the main reasons leading to transformer malfunction. Therefore, monitoring the operating temperature of the transformer and implementing alarm and control measures is very important.

Depending on the characteristics of the operating environment and protection requirements, scb11 33kv 35kv 2500kva dry type transformer transformers can be equipped with different enclosures. An IP20 protection enclosure is typically selected, which prevents solid foreign objects larger than 12mm in diameter, as well as small animals such as rats, snakes, cats, and birds, from entering and causing serious faults like short circuits and power outages, thereby providing a safety barrier for live parts. If scb11 33kv 35kv 2500kva dry type transformer needs to be installed outdoors, an IP23 protection enclosure can be chosen. In addition to the protection functions of IP20, the IP23 enclosure also prevents water droplets falling at an angle of up to 60° from the vertical from entering. However, the IP23 enclosure can reduce the transformer's cooling capacity, so attention should be paid to the derating of its operational capacity when selecting this option.

The cooling methods for scb11 33kv 35kv 2500kva dry type transformer are divided into natural air cooling (AN) and forced air cooling (AF). Under natural air cooling, the transformer can operate continuously at rated capacity for a long period. With forced air cooling, the transformer's output capacity can be increased by 50%. This method is suitable for intermittent overload operation or emergency overload operation. Since load losses and impedance voltage increase significantly during overload conditions, the transformer operates in a non economic state; therefore, it should not be allowed to operate under long term continuous overload.

The overload capability of scb11 33kv 35kv 2500kva dry type transformer depends on factors such as ambient temperature, load conditions before overload initial load, the transformer's insulation heat dissipation characteristics, and the thermal time constant. If necessary, the overload curve of the dry type transformer can be obtained from the manufacturer. Currently, the annual production capacity of resininsulated dry type transformers in China has reached 10,000 MVA, making China one of the largest producers and sellers of dry type transformers in the world.
