TYDZ-750KVA/0.415KV/0~6.3KV Contact Type Voltage Regulator

Mode: TYDZ-750KVA/0.415KV/0~6.3KV
Single phase             Frequency: 50Hz            Cooling methods: ONAN
Rated Capacity: 750kVA                                    Rated Output Voltage: 0~6.3kV
Regulating methods: Motor drive                     Rated Output Current: 0~119A
Rated Input Voltage: 0.415kV                           Aberration Ration of Waveform: ≤3%
Rated Input Current: 1807.9A                           Starting Voltage ≤1.5%
Short-circuit Impedance:≤7.5%(in range of 50%~100%,impedance is being linearity)
Mode of Regulation: electrical drive Operation Time: working for 30 min under 100% rated voltage
Short-circuit capability: When test transformer discharge to the test object via damping resistance under transient state, short-circuit current reach 2 times of rated value. The discharge last 8 circle will no damage regulator’s winding or mechanical distortion.
Temperature raise: temperature rise of oil surface is less than 55K., winding less than 65K
Product structure: ① There are upper and lower position limited, oil drain valve, oil level indicator      
                                 ②Regulating unit and raise voltage raising units are set together.
