Zusammenfassung: | The present invention relates to a dynamic guide control device for remote release of elevator, which makes the dynamic guide control device connected with a capacitor in a spare power supply of the elevator, connects a capacitor charging switch between the spare power supply and the capacitor, makes the capacitor connected in parallel with a motor rotation control switch group, and connects a capacitor discharge switch between the capacitor and the motor rotation control switch group. The motor rotation control switch group is respectively equipped with a first control switch in series with the fourth control switch, a third control switch in series with the sixth control switch, a fifth control switch in series with the second control switch, and then the above-captioned three control switches in series are connected in parallel so that the three-phase inputs of the motor are respectively connected between the first control switch and the fourth control switch, the third control switch and the sixth control |
