This product is also known as Scott transformer, is a three-se input into two single-se output transformer. The same requirements as two individual load capacity. Otherwise, the three-se current imbalance. It is widely used in industrial and mining enterprises in particular load situations, solve the problem of unbalanced three-se current, suitable for AC 50 / 60Hz frequency. The series transformer insulation thermal class level F. Three se to single se transformer core for high-quality cold-rolled silicon steel sheet orientation Diego area from the coil structure using cylindrical, oval and rectangular cylinder barrel. Small size, exnt performance, safety and reliability. Three se to single-se transformer is a special transformer, also known as T wiring transformer. It can use a three-se AC power into single-se AC power supply, as a large-capacity single-se power to the load, in order to improve the degree of unbalanced three-se power grid. Especially as with the melting of the power-frequency ideal omitted balancing capacitors and reactors.
Three se to single-se transformer is to enter into a three-se single-se output transformer. The three-se transformer input se currents close to balance. Frequency distortion. Other technical parameters and conditions of use and the same as ordinary dry-type transformers. It is higher than the cost of the isolation transformer. It is widely used in industrial and mining enterprises in particular load situations, solve the serious problem of unbalanced three-se current. This series of products suitable for AC 50 / 60Hz, operating voltage 1140V below. The series transformer insulation thermal class F, B, H level. This product is of high quality cold rolled oriented silicon steel core is made of convolution, the coil structure using cylindrical, oval and rectangular cylinder barrel. Small size, exnt performance, safety and reliability. Products produced by the national machinery of the standard JB / T 8750-1998 production.
FeaturesEnergy efficiency analysis:1. The use of high-quality cold-rolled silicon steel plates stacked; with special dipping process, oven drying! Effectively reduce vibration and noise during operation; and the introduction of the use of high temperature insulation materials and design new processes, new technologies, so that the transformer more energy, more quiet. Energy-saving and low noise coil ventilation slots left, smooth air flow, reduce the coil temperature.
2. Band product box: all with casters (100KVA below), voltmeter, ammeter, cooling fan, temperature controller, transformer temperature exceeds 80 ° start the fan, over temperature alarm (internal transformer exceeds 150 ° alarm protection use safety equipment above 100KVA with this feature).
