Abstract
The invention discloses a low-power elevator system which comprises an elevator control system, a first power unit, at least one elevator system without a counterweight and an enabling unit, wherein the elevator system without the counterweight comprises a second power unit, a motor, a traction pulley and a car, and the enabling unit comprises a third power unit, a generator, a flywheel and an energy storage unit. The invention makes it easier and more economical to suppress grid harmonics in an elevator system without counterweight. Furthermore, the invention can save costs for a power conversion unit between the electricity network and the elevator system, since this unit can be designed for a lower power rating than in the past.
Description
Technical field
Invention relates to a kind of technical field of low-power elevator system.
Background technology
The required power of the hoisting crane of elevator becomes with the various factors in the stage of the load that comprises elevator, speed, direct of travel and working cycle (operating cycle).It is favourable keeping power requirement as small as possible so that make the size of hoisting crane and required power connector size minimum.The traditional solution that is designed so that the power minimum that the moving elevator railway carriage or compartment is required is to be equipped with counterbalanced weight (counterweight) for every in elevator device elevator, counterbalanced weight is made into such size usually, and the quality that makes it is corresponding to about 50% of the quality of elevator car with full load.When along than double recipe when driving elevator, that is, surpass 50% cage or drive load downwards when being lower than 50% cage when upwards driving load, the main direction of power delivery is from the electrical network to the elevator motor.When quickening cage speed, need maximum instantaneous power in the beginning of working cycle.When light direction drives elevator, the potential energy of cage one counterweight combination reduces, and elevator motor is transformed into electric energy with mechanical energy.The power that produces during along light direction driving or braking elevator can be dissipated in the discrete resistors case and maybe can feed back in the electrical network.In comprising the eleva-tor bank of several elevators, it also is known that the power of an elevator generation can be used for along the solution that is included in other elevator of same eleva-tor bank than double recipe to driving.But, be supplied to other elevator in the elevator device to require to optimize the startup order and the direct of travel of cargo-carring elevator by different way the power that so produces, so that can flow (energy flow) in the assurance system all is in state of equilibrium constantly at each.Under this all working situation in elevator device all is impossible, and in this case, the power of generation may have to be dissipated in the resistance or with some other similar fashion and dissipates.Another kind of existing solution is that the hoisting crane with elevator device uses accumulator, the electric power that elevator device produces is stored allowing, so that be used for the elevator of the system that is included in later on.For example, specification sheets u$2003/0089557 has described by ultracapacitor is equipped with the power supply of elevator device with battery and has been connected, and can reduce the system of the power that elevator device obtains from electrical network.In this system, it is smooth that ultracapacitor is used to make the instantaneous power peak of the beginning of working cycle to flatten, and need battery to reduce required average power.
Summary of the invention
The present invention seeks to provides a kind of low-power elevator system at the defective that prior art exists.
The present invention adopts following technical scheme for achieving the above object:
Low-power elevator system of the present invention, it is characterized in that comprising apparatus for controlling elevator, first power cell, at least one non-counterweight elevator system and one enable the unit, wherein non-counterweight elevator system comprises second power cell, electrical motor, hauling block and car, enable the unit and comprise the 3rd power cell, electrical generator, flywheel and energy-storage units, the input end of first power cell gets access to grid, the mouth of first power cell connects the input end of second power cell and the 3rd power cell respectively, the mouth of apparatus for controlling elevator connects the input end of second power cell and the 3rd power cell respectively, the mouth of second power cell is connected in series electrical motor successively, hauling block, hauling block is connected with car by hauling rope, the mouth of the 3rd power cell is connected in series electrical generator successively, connect the input end of second power cell behind flywheel and the energy-storage units, the input end of output termination second power cell of the 3rd power cell.
The obtainable advantage of the present invention is owing to reduced connection power and can use low-pass filter, can not suppress mains by harmonics easier and economically in adding the counterbalanced weight elevator device.And the present invention can save the cost of the power conversion unit between electrical network and the elevator device, because this unit can be the rating horsepower design lower than the past.
Obtainable another advantage of the present invention is, can be for a long time, for example, in the morning and in the time between the afternoon peak load conditions, even in the interval longer than this time stored energy.And the accumulator in the elevator device of the present invention is environmental protection and durable, can repeat energy supply many times.
