详细内容

 SD9000-L-E微机有刷励磁装置

 

可应用于各种可控硅整流励磁(零式、三相半控桥、三相全控桥、单相半控桥、单相全控桥及交流励磁机方式),功能强,性能可靠。

 

性能特点:

1、起励后,调节器调整机端电压为100%ue(380V)

2、断路器跳闸时防止机组过电压,机端电压为380V(使用全控桥方式,该性能佳)

3、防止低频过流功能,当频率低于40HZ时,自动关断可控硅。提高机组安全性。

4、超亮数码管显示本机频率,方便直观。

5、调节器采用双电源供电,运行中若厂用电消失,可以靠本机提供的电源继续工作。

610%阶跃响应:超调量<5%,振荡次数1次,调节时间<3秒。

7、甩额定无功负荷:超调量<15%Ue,振荡次数<3次,调节时间<5秒。

8、可控硅控制角分辨率:0.036度。

9、强励位数>1.3倍。


SD9000-L-E microcomputer with brush excitation device

 

SD9000-LE microcomputer brush excitation device can be applied to a variety of SCR rectifier excitation (zero, three-phase half-controlled bridge, three-phase full control bridge, single-phase half-controlled bridge, single-phase full control bridge and AC exciter mode ), Strong function, reliable performance.

 

Features:

1, from the excitation, the regulator to adjust the terminal voltage of 100% ue (ie 380V).

2, circuit breaker tripping to prevent over-voltage unit, the terminal voltage of 380V (using full-controlled bridge mode, the best performance)

3, to prevent low-frequency over-current function, when the frequency is lower than 40HZ, the automatic shutdown thyristor. Improve unit safety.

4, ultra-bright digital display of the machine frequency, convenient and intuitive.

5, the regulator uses dual power supply, running in the plant if the electricity disappears, you can rely on the power supply to continue working.

 

Technical Parameters:

1, pressure regulating range: (30% -130%) Ue

2, high-pressure accuracy: better than 0.5%

3, the height difference coefficient: +8%

4, the frequency characteristics: 1% change in frequency, the generator terminal voltage change <0.1% Ue.

5, zero from the boost: high volume <10% -15%, adjust the time 3-5 seconds, the number of oscillation 3-5 seconds.

6,10% Step response: overshoot <5%, the number of oscillation 1, the adjustment time <3 seconds.

7, rejection of the rated reactive load: overshoot <15% Ue, the number of oscillation <3 times, the adjustment time <5 seconds.

8, SCR control angular resolution: 0.036 degrees.

9, strong excitation bit> 1.3 times.
