Description
Technical field
The utility model relates to elevator energy-saving technology, especially designs frequency conversion energy feedback control system.
Background technology
Since First elevator in 1889 is born, so far, elevator kind is more and more, and the technology of elevator is gradually to networking, high-endization, intellectuality, energy-saving development.2011 approximately 450,000 of Nian， China elevator volume of production and marketing, compare increasing degree approximately 23% in 2010.In the past few years, China's elevator output, recoverable amount and annual increment are the first in the world.Current science and technology is developed by leaps and bounds, and mankind's demand is day by day harsh, and further investigation has great significance with the elevator technology development of analyzing latest development ，Dui China of world's elevator technology.Due in recent years, the quantity of elevator is more and more.In the electricity consumption condition survey statistics such as Dui hotel, office building, show, elevator power consumption accounts for the more than 17%～25% of total electricity consumption, is only second to idle call electric weight, higher than the power consumption of illumination, water supply etc.
In actual use, the part that elevator power consumption is larger is: for driving the motor of elevator cage operation need to consume excessive energy.Investigation shows, the electric weight that the motor of elevator consumes while dragging cage operation accounts for 72% of gross energy.The energy-efficient of motor drive system will become the core that realizes elevator energy-saving.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiency that above-mentioned prior art exists, and proposes a kind of frequency conversion energy feedback control system for elevator energy-saving.
The technical scheme that the utility model proposes for above-mentioned technical problem comprises, proposes a kind of frequency conversion energy feedback control system for elevator energy-saving mainly frequency converter, IPM module, peripheral circuit three parts, to consist of; Wherein, described IPM module, is mainly comprised of IPM element, isolating diode, high-order harmonic filtering device, and described high-order harmonic filtering device, three chokes reactors and four electrolytic capacitor filters, consists of; Described peripheral circuit, mainly consists of single chip microcomputer, programmable logic chip, peripheral signal collector; Described IPM module is connected with one end of frequency converter by the chokes reactor of high-order harmonic filtering device, and the other end of frequency converter is connected with peripheral circuit.
Described high-order harmonic filtering device, the higher harmonic current that can effectively stop IPM element to produce enters electrical network, can improve the Electro Magnetic Compatibility of variable frequency feedback system.
Described peripheral circuit, can control the normal operation of IPM module in order, guarantees direct current energy feedback timely and realizes smoothly regeneration.
In elevator, use this frequency conversion energy feedback control system, can successfully realize converting the direct current energy storing in electric capacity to AC energy and be transmitted back to electrical network, power saving rate reaches 30%～40%.In addition, in described frequency conversion energy feedback control system, non-resistance heater element, has reduced the ambient temperature of machine room, has also improved the operating temperature of apparatus for controlling elevator simultaneously, and control system is no longer crashed, and extends elevator useful life; Machine room can not re-use the heat dissipation equipments such as air-conditioning, can save the power consumption of air conditioner in machine room and heat dissipation equipment, and energy-conserving and environment-protective make more power saving of elevator.And described IPM module, speed is high, precision is high, stability is good, antijamming capability is strong; Can guarantee that output voltage is accurate, prevent electric current loopback, frequency converter is not affected, in the use occasion of frequent braking, economize on electricity more obvious.
