Embodiment approach 1

[0028] The present invention is used for lifting type vertical elevator, and the control switch S_** in the circuit is an external call elevator button using double contacts or single contacts, which is processed by diode D_** isolation, and the circuit is set in the elevator on each floor On the outside signboard, when no one is using the elevator for a long time, the elevator control cabinet sends out a power-saving signal to control the power-off of the entire circuit, and only the duty relay is kept working at low voltage; when someone presses the call switch, the power-on relay is activated, and immediately Activate the whole circuit and the elevator starts working.

Embodiment approach 2

[0030] The present invention is used for lifting vertical elevators, but the control switch does not use a manual button switch, the control switch uses an infrared sensor automatic switch, the power supply of the infrared sensor is connected to the indicator light, and the output of the infrared sensor is serially connected to the control line of the power-on relay Package, when the entire elevator is in a power-saving state, the infrared sensor starts to work; when someone stands in front of the elevator door, the infrared sensor sends out a signal by sensing the heat energy of the human body, activates the power-on relay, and then activates the entire circuit, and the elevator starts to work .

Abstract

The invention discloses an energy-saving circuit of an elevator. A power contactor, a duty relay, a switching power supply and a power-on relay are added between an elevator control cabinet and an elevator distribution box. Main contacts of the power contactor are connected between three-phase power lines of the elevator distribution box and the elevator control cabinet in series, the switching power supply is powered up by the elevator distribution box and outputs power to the duty relay and the power-on relay, the duty relay is connected with the power-on relay, and the duty relay and the power-on relay are respectively connected with control signal lines of the elevator control cabinet. In the energy-saving circuit, the power contactor does not work and consume no power in an energy-saving state, only the duty relay actuates and all external indicator lights work, the power-on relay consumes power only by pressing a button, and the power consumption of the power-on relay can be ignored. Elevators are used more and more day by day and the amount of elevators is large, so saved energy is tremendous, and the energy-saving circuit has a huge economic popularization benefit.

Description

technical field [0001] The invention relates to the field of energy-saving control, in particular to an energy-saving circuit for elevators. Background technique [0002] With the development of real estate, the number of elevators is increasing, among which residential elevators account for a large proportion. Due to the characteristics of residential elevators, their management adopts the continuous operation mode of 24 hours a day. The use density of residential elevators is high during commuting and commuting hours, and the frequency of use is very low at other times, especially from 10:00 pm to 6:00 am the next day. Almost no one uses them. And the fan is automatically turned off, but the control part of the elevator, the frequency converter and the internal and external display must be turned on, and these parts still need to consume a certain amount of power in vain. This part of electric energy accounts for a very small proportion of the daily energy consumption of ...
