Dongying Transformer Factory Changneng Dry type Transformer SCB10 Price

Description :

　　The cooling methods for dry-type transformers are divided into natural air cooling and forced air cooling. Under natural air cooling conditions, the transformer operates at its rated capacity for a long time. If forced air cooling is used, the output capacity of the transformer will increase by 50%. Suitable for intermittent overload operation or emergency overload operation, the load loss and impedance voltage increase significantly during overload, and it is in a non economic operating state, so it is not desirable to operate continuously for a long time.

　　The overload capacity of dry-type transformers is related to the ambient temperature, the load condition before overload (initial load), the insulation and heat dissipation conditions of the transformer, and the heating time constant. As needed, the overload curve of dry-type transformers can be requested from the manufacturer.

　　How to utilize the overload capacity of dry-type transformers?

　　(1) When calculating the capacity of the transformer, it can be appropriately reduced. Please fully consider the possibility of short-term impact overload of some rolling, welding and other equipment. Fully utilize the overload capacity of dry-type transformers and reduce their capacity. For areas with partial load imbalance, residential areas with nighttime lighting as the center, and department stores with air conditioning and daytime lighting as the center. Fully utilize its overload capacity, appropriately reduce the transformer capacity, and keep the main operating time at full load or short-term overload state.

　　Dry type transformers have the advantages of short circuit resistance, low maintenance workload, high operating efficiency, small size, and low noise, and are often used in places with high performance requirements such as fire and explosion prevention.

　　1. Safe, fireproof, pollution-free, and can operate directly in the load center.

　　2. Adopting advanced domestic technology, it has high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability, and long service life.

　　3. Low loss, low noise, significant energy-saving effect, and maintenance free.

　　4. Good heat dissipation performance, strong overload capacity, and can improve the capacity operation during forced air cooling.

　　5. Good moisture resistance, suitable for working in harsh environments such as high humidity.

　　6. Dry type transformers have perfect temperature measurement and protection systems. Intelligent start system and automatically activate signal lights.

　　7. Small size, light weight, small footprint, and low installation cost.
