The invention discloses an elevator band-type brake power supply, an elevator control system and an elevator. The elevator band-type brake power supply comprises a rectifying circuit, a switching circuit and a time adjusting circuit. The switching circuit is connected in the rectifying circuit, the output end of the time adjusting circuit is electrically connected with the control end of the switching circuit, and when an alternating current is connected to the alternating current input end of the rectifying circuit, the time adjusting circuit controls the on-off duration of the switching circuit through the control end of the switching circuit and can enable the switching circuit to be switched off after the switching circuit is switched on for a preset duration. The time adjusting circuit comprises a time delay circuit, and the preset duration of the switching circuit can be adjusted by adjusting parameters of the time delay circuit. According to the invention, the output duration of the excitation voltage is adjusted through the time adjusting circuit, and the power supply has the functions of a large current and adjustable excitation voltage maintaining duration. The power supply can cover multiple small-current low-power products of the same type downwards, is easy to operate, concise and easy to understand, and is flexible in application, high in compatibility and suitable for multiple elevator band-type brake systems compared with products on the current market.

    本发明公开了一种电梯抱闸电源、电梯控制系统及电梯,包括整流电路、开关电路和时间调节电路。开关电路连接在整流电路中,时间调节电路的输出端与开关电路的控制端电性连接,时间调节电路在整流电路的交流输入端接入交流电时,通过开关电路的控制端控制其导通和关断的时长,且能够控制开关电路导通预设时长后断开,时间调节电路包括延时电路,开关电路的预设时长可以通过调整延时电路的参数进行调整。本发明通过时间调节电路调节激励电压的输出时长,同时具有大电流、激励电压维持时长可调的功能。可向下覆盖多款小电流低功率的同类型产品,并且操作简单,简明易懂,相较于当前市场上产品,本发明应用灵活,兼容性强,适用于多种电梯抱闸系统。
