Description of drawings
Fig. 1 is the operation principle block diagram of elevator battery saving arrangement of the present utility model.
Embodiment
In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.
Consult shown in the accompanying drawing, to be applied to a frequency converter is that the elevator control cabinet of 380V 50HZ 15KW is reference, this intelligent energy-saving controller comprises capacitor switch (10), ultracapacitor and auxiliary circuit (20), control circuit (30), filter inductance (40), harmonic wave control current transformer (50), electrochemical capacitor (60), harmonic wave control filter capacitor (70).The frequency converter dc terminal inserts the input of capacitor switch (10), the output of capacitor switch (10) is connected with the input of ultracapacitor and auxiliary circuit (20), external power source is connected with the output of filter inductance (40), the input of filter inductance (40) is connected with the interchange interface end of harmonic wave control with current transformer (50), harmonic wave control is connected with filter capacitor (70) with harmonic wave control respectively at electrochemical capacitor (60) with the DC interface end of current transformer (50), control circuit (30) respectively with harmonic wave control with current transformer (50) control end, capacitor switch (10) control end, ultracapacitor and auxiliary circuit (20) control end is connected.
Simultaneously, the harmonic wave control in this intelligent energy-saving controller can be V-type groove metal-oxide-semiconductor field effect transistor (VMOS), igbt (IGBT), integral gate change transistor (IGCT), smart power switch device and drive circuit integration module (IPM) or intelligent power integrated circuit (SPIC) with the power device that is comprised in the current transformer (50).
External power source is received harmonic wave control current transformer (50) through filter inductance (40).The harmonic current signal of gathering according to the current transformer of other installation, the direct current that harmonic wave control is understood in the electrochemical capacitor (60) that its DC interface end is connected with current transformer (50) carries out inversion, the harmonic wave control electric current that the interchange interface end of current transformer (50) will be exported and the harmonic wave size of current equates, direction is opposite.By the way of positive and negative counteracting, the harmonic wave that frequency converter produces is administered.The electric energy loss that harmonic wave produces will be eliminated.
To be in underloading up when elevator, heavy duty is descending, under the operating modes such as flat bed stop, motor is in generating state, this moment, frequency converter can absorb the regenerative electric energy of motor output in the frequency converter interior capacitor, the direct voltage of dc bus side continues to rise, when rising to the voltage 600V of the middle setting of control circuit (30), control circuit (30) will send signal and give capacitor switch (10), the frequency changer direct current bus side will be switched to ultracapacitor and auxiliary circuit (20) and it will be charged by capacitor switch, no longer carry out consumed power by brake resistance in the mode of heating; Be not in when elevator under the operating modes such as underloading is up, heavy duty is descending, flat bed stop, motor is in motoring condition, this moment, the direct voltage of frequency changer direct current bus side continued to descend, when dropping to the voltage 560V of the middle setting of control circuit (30), control circuit (30) will send signal and give capacitor switch (10), and ultracapacitor and auxiliary circuit (20) will be switched to the frequency changer direct current bus side and it is discharged by capacitor switch (10).So just changed the present situation that electric energy that former frequency changer direct current bus produces is generated heat and consumed by brake resistance.This part electric energy has obtained regeneration, has saved electric energy.
