Abstract

本实用新型是一种采用伺服电机控制调压器的 三相交流稳压器，其特征是三相电压独立调节，互不 牵连。在三相输入电压，严重不平衡时，能保证输出 三相电压是平衡的。因此可用于三相不均衡负荷，单 相负荷。特别适合电网电压很低的一般稳压器不能 正常工作的条件下工作。

Description

本发明是一种采用伺服电机控制调压器的三相交流稳压器。
广泛使用的调压器式的三相交流稳压器，其输出的三相交流电压不平衡，每相电压不能独立调节，输出电压调节范围窄。这是因为三个调压器是同轴的、三相电压只能同步变化。按普通方式接线的调压器，其输入输出升压比＜1.3。过低的输入电压经升压后依然达不到额定输出电压值。
本发明的第一个目的是提供一种三相交流电压平衡，各相可独立调节，互不牵连的交流稳压器。
本发明的第二个目的是提供一种输出电压调节范围宽，输入电压很低时也能保证输出电压达到额定值的交流稳压器。
本发明采用三个伺服电机控制三个独立的不同轴的调压器。并将调压器输入（出）端作为输出（入）端的方式制作交流稳压器。
如图1.为自动交流稳压器原理图，伺服电机M1、M2、M3分别控制B1、B2、B3调压器当输出端A′相或B′C′相电压过低时。信号经0－－1端输入到信号检测处理电路MC中。经比较放大，MC输出指令，使伺服电机M1正向运动，带动调压器B1调节臂X1运动使输出电压A′升高，直到A′输出电压为额定值为止，反之亦然。
采用新型交流稳压器可大大减少因三相电压不平衡或输入电压，太低使用电器不能正常工作的情况发生。

Claims (3)

1、一种采用调压器的三相交流稳压器，其特征是三个调压器由三个伺服电机控制互不牵连。
2、一个如权利要求1所述的三相交流稳压器，其特征是调压器活动臂接电源输入端。调压器输入端为稳压器输出端。
3、一个如权利1和2所述的三相交流稳压器。其特征是三个调压器输入、输出为星形接法。
