为了消除电气安装中单项三眼插座接线错误,我们试制了一种在尚未通电的情况下检查装置,整个检测装置均设在一个单项三眼插头上,利用四节15Ｖ干电池来判断和检查单项三眼插座接线正确与否,共有七种功能。检测时只要将三眼插头插在被检测的插座上,便可以立即判断单相三眼插座的接 In order to eliminate the error of single three-eye socket wiring in electrical installation, we tried to test the device without power. The whole detection device was set on a single three-eye plug, and four 15V dry batteries were used to judge and check single item three. Eye socket wiring is correct or not, there are seven functions. When testing, just plug the three-eye plug into the tested socket and immediately judge the connection of the single-phase three-eye socket.
