【技术实现步骤摘要】
本技术涉及民用单、三相供电系统中用于调压、稳压的装置,特别是一种单、三相交流稳压装置。中国专利CN2066164U公开了一种"家用自动交流稳压器",它能在电网电压波动时,输出额定电压满足需要;它的不足之处是由于采用自耦变压器,在高端和低端抽头输出时,输出功率受到变压器的限制,而只有额定的1/2,并且它的功能单一、实用范围窄小,不能调压定时。本技术的目的是提供一种单、三相交流稳压、调压及定时组合为一体的稳压装置。本技术的目的可以通过以下技术方案来解决。由稳压单元、采样单元、控制单元、调压单元、定时单元构成的稳压装置,其特征是电网电压经过由BG1-BG2、J1-J3、T1构成的稳压单元再经由可控硅SCR、稳压器W1及二极管D1构成的调压单元输送到负载上;同时,电网电压的波动信号在稳压单元之前被由二极管D6及采样变压器T2构成的采样单元采集并送入由比较器IC1及稳压电阻W2-W3构成的控制单元进行判断后,送出执行信号,经稳压单元完成稳压目的。上述交流稳压装置,在稳压与调压单元之间设有开关K,当开关K拔向2位置时,调节W1调压旋钮可得到0~220±10%伏的无级可调 ...
