SD9000 excitation control panel

SD9000 low-voltage microprocessor excitation control panel hydropower units are specially designed to solve the low-hydropower unit microcomputer excitation system designed products. The control panel of the computer SD9000-LE brush excitation device, thyristor rectifier circuit, excitation transformers, KELY loop, off the magnetic circuit, power components, display circuit, operating circuit, the power supply circuit components. Brushless excitation units only need SD9000-LW brushless excitation device to the computer, SD9000-LW computer brushless excitation device can be placed in the automation control panel for the user to save costs. Features: 1 Kai Li, adjust the terminal voltage regulator is 100% Ue (ie 380V) 2 units when the circuit breaker trips to prevent over-voltage terminal voltage of 380V.. 3. Prevent low frequency overcurrent function, when the frequency is below 40HZ, automatic shut-off thyristor, improve crew safety. 4 ultra-high frequency digital display of the machine for easy and intuitive. 5. Regulator with dual power supply, power plants disappear if the operation can be provided by the machine's power to continue working. Technical parameters: 1 pressure range:. (30% -130%) Ue 2 regulator parameters: better than 0.5% 3 regulator factor: +8% 4 frequency characteristics: frequency every 1% change in the generator terminal voltage variation <0.1% Ue 5 from zero boost: overshoot <15%, the adjustment time 3-5 seconds, oscillation frequency of 3-5 times a 6.10% step response: Ultra excess <15% Ue, the oscillation frequency 1 times, regulation time <3 seconds 7 thrown rated reactive load: overshoot <15% Ue, shock frequency <3 times, 1.3 times the adjustment time
