Abstract

The invention provides an elevator energy-saving device. The elevator energy-saving device is connected with a power network, and comprises a controller, a traction motor and a battery pack; one end of the controller is connected with the power network, and the other end of the controller is connected with the traction motor and the battery pack; the controller is used for rectifying and invertingalternating current output by the power network to output the rectified and inverted alternating current to the traction motor for driving the traction motor to work; the controller is also used forcontrolling the power network to charge the battery pack; when an elevator is in the descending running state, the controller is also used for modulating alternating current generated by the tractionmotor into direct current to output the direct current to the batter pack for storage. According to the elevator energy-saving device, the elevator running safety is improved while energy is saved.

Description

【Technical field】 [0001] The invention relates to the technical field of elevators, in particular to an energy-saving device for elevators. 【Background technique】 [0002] During the operation of the elevator, due to the counterweight of the elevator system, it does not consume electric energy when it decelerates or brakes. The kinetic energy and potential energy of the elevator are converted into electrical energy by the motor and stored in the DC side capacitor of the inverter. This part of energy is usually converted into heat energy by the energy-consuming resistor and wasted, thereby preventing the voltage of the capacitor in the inverter from being too large. However, the energy consumption of resistors not only reduces the efficiency of the system and wastes energy, but also the large amount of heat generated by the resistors deteriorates the environment around the elevator control cabinet and reduces the safety of elevator operation. [0003] In view of this, it is...
