Abstract
The utility model discloses an electricity economizer for an intelligent handrail elevator and belongs to the technical field of a power saving device. The electricity economizer for the intelligent handrail elevator comprises a frequency converter connected between a power supply and a motor, wherein the back of the power supply is additionally provided with a power saving control contactor KM2 and a by-pass contactor KM1; the frequency converter is also connected with a PID intelligent regulator and a photoelectric induction switch sequentially; an AC reactor is arranged in front of the frequency converter; and a by-pass system is also connected between the power supply and the motor. The utility model has the advantages that under the condition without passengers, the operation speed of the elevator is very low, so that wear of a mechanical part is greatly reduced and the service life of a handrail is prolonged relatively; the soft starting technology can greatly reduce impact to a power system when the motor is started; starting, stopping or speed conversion are stable and smooth and the comfortable feeling is good; compared with the conventional control, energy saving of the variable frequency control is the mostly valuable significance; the electricity economizer controls the operation state of the elevator according to the amount of people on the elevator; and the power rate is over 20 percent.
Description
Technical field
The utility model discloses a kind of intelligent handrail elevator electricity-saving appliance, belong to the battery saving arrangement technical field.
Background technology
Handrail elevator can exceed actual needs power more than 20% with the power of motor that uses generally speaking owing to consider actual power or service condition.Elevator is obviously wasted electric energy owing to be in intermittently no-load run for a long time.
The utility model content
In order to address the above problem, the utility model provide a kind of can saves energy, can improve precision benefit pulsation-free handrail elevator electricity-saving appliance again.
The scheme of the utility model technical solution problem is as follows: a kind of intelligent handrail elevator electricity-saving appliance, it is characterized in that: comprise the frequency converter that is connected between power supply and the motor, wherein be equipped with economize on electricity control contactor KM2 and bypass contactor KM1 behind the power supply, frequency converter links to each other with PID intelligent regulator, photoelectric sensor switch again successively, the AC reactor wherein is installed before the frequency converter, is connected with bypath system between power supply and the motor again.The quantity of described photoelectric sensor switch is two.Help from two bringing in the amount of passenger on the induction electricity ladder up and down.The detected signal of photoelectric sensor switch can be regulated at any time by the PID intelligent regulator, makes frequency converter be in an optimum Working.Described frequency converter input end is equipped with reactor.The installation of reactor can suppress the generation of harmonic wave, effectively reduces the influence of the high order harmonic of input to electricity-saving appliance, the service life of also having improved motor.
The utlity model has following advantage:
1, since during no passenger elevator speed very low, the wearing and tearing of mechanics will reduce greatly, prolong the service life of staircase relatively;
When 2, soft Starting Technology can reduce electric motor starting greatly to the impact of electrical network;
3, start, stop or the rate conversion steady and smooth, comfort is better;
4, variable frequency control and traditional control ratio, energy conservation is of practical significance most, according to the running state of how much controlling elevator of personnel on the elevator, electric rate is more than 20%.
Description of drawings
The circuit principle structure block diagram that Fig. 1 implements for the utility model.
The specific embodiment
As shown in Figure 1, the utility model handrail elevator electricity-saving appliance comprises the frequency converter 3 that is connected between power supply 1 and the motor 4, wherein be equipped with economize on electricity control contactor KM2 and bypass contactor KM1 behind the power supply 1, frequency converter 3 links to each other with PID intelligent regulator 7, photoelectric sensor switch 6 again successively, wherein before the frequency converter 3 AC reactor 2 is installed, is connected with bypath system 5 again between power supply 1 and the motor 4.Bypath system 5 is directly joined with power supply 1 and motor 4.The quantity of photoelectric sensor switch 6 is two.
Working process of the present utility model is:
1, give frequency converter 3 input parameters needed, run up time, acceleration and deceleration time, operation scheme, display mode etc.
2, power-on 1, and electric current is through reactor 2, frequency converter 3 soft start handrail elevator motors 4, and can regulate this run up time, and soft start has good protective effect to motor 4, has reduced the mechanical damage of fly start to motor; By the detection of 6 pairs of elevator passenger flows of photoelectric sensor switch, give 7 one electric signal of PID intelligent regulator, change to frequency converter 3 by PID intelligent regulator signal again, change the running frequency of motor by frequency converter 3.On elevator the passenger after a little while the running frequency of elevator also decrease.With reducing the use power of motor greatly, make electricity-saving appliance enter power save mode.
3, break down when frequency converter 3, disconnect KM2 economize on electricity loop and withdraw from use, open KM1 bypath system 5 and can devote oneself to work, guaranteed the normal operation of elevator.
