Abstract
A small parting apparatus arranged in a single plane parking space is mainly suitable for small units or families, the power of a motor of the small parting apparatus is not larger than 5kw, a three-phase asynchronous motor is employed, and the motor is directly started in the prior art. The parking apparatus is heavy-load started at most occasions, and large impacts are formed on the motor, mechanical devices and external power sources when the motor is directly started. The parking apparatus simply employing the three-phase asynchronous motor cannot be used under a condition that only a single-phase AC power source supplies power. By employing the mature frequency conversion speed regulation technology, when only the single-phase AC power source serves as the external power source, the parking apparatus can go on using the three-phase asynchronous motor by the use of a frequency conversion speed regulation device employing a single-phase input and three-phase output manner, so that the application range and universality of the product are improved. The frequency conversion speed regulation device is advantaged by stable starting, adjustable speed, rapid braking, energy conservation and environmental protection.
Description
Technical field
The present invention relates to mechanical parking equipment field, be specifically related to the small parking equipment that arranges in single parking stall and adopt variable-frequency control technique, with increase motor and deceleration device versatility, improve electric motor starting, acceleration, deceleration and braking ability and reach energy-saving effect.
Background technology
Along with the increase of automobile pollution, the problem of parking space deficiency becomes clear day by day, and mechanical parking equipment is used widely.Parking apparatus, comprising the small parking equipment arranged on single plane parking stall, is mainly applicable to flatlet or family, and the power of motor of the type parking apparatus is no more than 5kw, adopts threephase asynchronous machine directly to start.Because parking apparatus is heavy load starting in most occasion, directly starts and can produce larger impact to motor, mechanical device and external power source.But, under home environment, usually only have that single phase alternating current power supply is powered, the wire diameter of supply line is often less than normal; The garage, community built up, also only has single phase alternating current power supply to power usually.Because the starting characteristic of load motor is poor, manufacture and control cost also relatively high.And use the load motor directly started under home environment, if electric current is excessive when starting, other household appliances used above same supply line will affect greatly.For caution's sake, the universal product of parking apparatus producer does not provide applicable single phase alternating current power supply input queued switches, namely installs the parking apparatus of load motor.
Adopt ripe variable-frequency control technique, when external power source only has single phase alternating current power supply, adopt single-phase input, RHVC that three-phase exports can make parking apparatus continue to adopt threephase asynchronous machine and without the need to adopting monophase machine.When external power source is three-phase alternating-current supply, adopts three-phase input, RHVC that three-phase exports also can give full play to the advantages such as the startup that frequency control has is steady, speed is adjustable, braking is rapid, energy-conserving and environment-protective.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, ripe variable-frequency control technique is adopted at small parking equipment, select threephase asynchronous machine as power source, only need be single phase alternating current power supply or three-phase alternating-current supply according to the external power source of reality access and select the converter plant of suitable rectifier, then suitably change the motor winding connection mode of connection box for motor.
For achieving the above object, the small parking equipment of a kind of frequency control of the present invention, the feature of its technical scheme is: the small parking equipment that described small parking equipment refers to setting on single plane parking stall, single motor power is no more than 5kw, comprises the two-layer parking apparatus of various single lifting form and the two-layer parking apparatus of upper strata vehicle-containing reach rotation or lower floor's vehicle-containing reach rotated versions; Described frequency control refers to and adopts ripe converter technique, when the external power source of reality access parking apparatus is three-phase alternating-current supply input, selection rectification part is three-phase input, the three-phase output RHVC of three-phase bridge rectifier, and the threephase asynchronous machine driven is star connection or delta connection; And when the external power source of actual access parking apparatus is single phase alternating current power supply input, selection rectification part is single-phase input, the three-phase output RHVC of single-phase bridge rectifier, the threephase asynchronous machine driven is required to be delta connection, to reach enough powers of motor and moment of torsion.
The present invention's RHVC in one's power belongs to power frequency, discontinuous operation, focus on and start speed governing, most simple application without the need to overclocking high-speed cruising.
RHVC is the electric energy utilizing the on-off action of power semiconductor device power frequency supply to be transformed to another frequency, controls to export the device that motor realizes speed governing.At present extensively, the ripe RHVC used mainly adopts interchange-AC/DC mode (be called VVVF frequency conversion or be called Vector Control Frequency Conversion), first power frequency AC is converted to dc source by rectifier, and then dc source is converted to all controllable AC power of frequency, voltage to supply motor.The circuit of RHVC is generally made up of rectification, intermediate DC link, inversion, control four parts.Wherein, rectification part is that the AC power of input is carried out rectification by rectifier, obtained approximate dc source; Intermediate DC link part is filtering, DC energy storage and buffering reactive power; Inversion part is IGBT three-phase bridge type converter, and exports as PWM waveform; Control the output control that part then carries out frequency, voltage according to actual needs.
The input power of common RHVC is three-phase alternating-current supply, is called three-phase input, three-phase output RHVC; As required, also there is input power to be single phase alternating current power supply, for driving small-power triphase asynchronous motor, being called single-phase input, three-phase output RHVC.The RHVC of above-mentioned two kinds of forms, maximum difference is wherein rectification part.The rectification part that three-phase input, three-phase export RHVC is three-phase bridge rectifier, and the rectification part of single-phase input, three-phase output RHVC is single-phase bridge rectifier; Certainly, the voltage waveform that the voltage waveform exported due to three-phase bridge rectifier exports than single-phase bridge rectifier is closer to direct current, therefore the intermediate DC link of RHVC partly, and single-phase input form need have more consideration in filtering process; In addition, three-phase input, three-phase export RHVC and single-phase input, three-phase export the basic indistinction of RHVC.Certainly, under the prerequisite not increasing extra boosting process or step-down process, the output line voltage that three-phase input, three-phase export RHVC is 380v, therefore the small-power triphase asynchronous motor many employings star connection driven.And the output line voltage of single-phase input, three-phase output RHVC is 220v, therefore the small-power triphase asynchronous motor driven must adopt delta connection, to reach enough power and moment of torsion.If still adopt star connection, then the real output of motor and moment of torsion will be less than rated value.
The control part of RHVC comprises single chip computer device or special DSP digitial controller chip and is provided with the communication interface with external device (ED), accepts outside reasonably control instruction and also controls the output of RHVC accordingly.With regard to the technical program, the two-layer parking apparatus of single lifting form only has a lifting motor to need to control, and in fact only needs a low rate start operation curve, at most increase by be about to run the curve that runs slowly put in place; Rotate for the reach of upper strata vehicle-containing or the two-layer parking apparatus of lower floor vehicle-containing reach rotated versions, then the operation increasing a shift action and a spinning movement on the basis of the above again controls.And these control to be all can preset, the needs that run, control communication interface partly send control instruction and can realize by the form of agreement to RHVC by the control system of parking apparatus according to this.The rated output of all drive motors wherein maximum motor that the rated output of RHVC must select to be more than or equal to parking apparatus.
The advantage of the technical program is: the occasion of powering only having single phase alternating current power supply, also can utilize ripe variable-frequency control technique, use threephase asynchronous machine to drive small parking equipment, and the adverse effect produced when greatly reducing electric motor starting.When external power source is three-phase alternating-current supply, the advantages such as RHVC starts steadily, speed is adjustable, braking is rapid, energy-conserving and environment-protective more can be played.
