TYDZ-750KVA/0.415KV/0~3.15KV Contact Type Voltage Regulator

Mode: TYDZ-750KVA/0.415KV/0~3.15KV
Single phase        Frequency: 50Hz           Rated Capacity: 750kVA
Rated Input Voltage: 0.415kV                     Rated Output Current: 0~47.6A
Rated Input Current: 361.4A                       Aberration Ration of Waveform: ≤3%
Rated Output Voltage: 0~3.15kV               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 15 min under 100% rated voltage and current
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.
