630 KVA Dry Type Step-Up Transformer Basic parameters:
Rated power: 630 KVA (kilowatts)
Voltage ratio: Common voltage ratios include 380V/1200V or 380V/1140V, which can increase the lower input voltage to a higher output voltage to meet different needs
Power phases: Three-phase, suitable for most three-phase electrical equipment
630 KVA Dry Type Step-Up Transformer Features and advantages:
Solve the problem of low voltage: During the construction of the water diversion tunnel, if the high-voltage grid voltage is low or the low-voltage line is too long, causing the equipment to fail to operate normally, the transformer can increase the voltage to a suitable range, allowing the equipment to start and work normally
Deal with too many equipment: When the number of electrical equipment used in the construction is too low, the transformer can increase the voltage to ensure that the equipment is normal. Normal operation
Cost-effectiveness: Compared with the use of unit generators to generate electricity, it saves about 40-50% of the cost, and the purchase cost and maintenance cost are low
630 KVA Dry Type Step-Up Transformer Working principle:
Electromagnetic induction principle: Through the winding structure and electromagnetic interaction inside the transformer, the input voltage is increased to the required output voltage value. The ratio of the number of turns of the primary and secondary coils determines the voltage conversion ratio
