Abstract
A storage facility for regenerative energy consists of two high frequency electronic switching devices, a large volume capacitor and an inductance. The three-phase current is rectified and filtered by a rectifier and changed into an AC current which is inverted to three-phase current or one-phase current through an inverter, then the output of three-phase current or one-phase current is connected with a load. The connection mode of the utility model is that one high frequency electronic switching device is in series connected with another high frequency electronic switching device and then is in parallel connected with the positive electrode and the negative electrode of the AC circuit; the large volume capacitor is in series connected with the inductance, the other end of the large volume capacitor is connected with the negative electrode of the AC circuit, and the other end of the inductance is connected with the series connection joint of one high frequency electronic switching device and another high frequency electronic switching device. The utility model can store the regenerative energy as well as reuse the stored regenerative energy, thereby not only realizing energy saving but also ensuring the normal operation of the circuit and the current-using equipment.
Description
Technical field: the utility model relates to energy storing device, relates in particular to a kind of storage device of regenerated energy.
Background technology: frequency conversion speed-adjusting system is extensive use in pump class, fan-type load, and function admirable, energy-saving effect are obvious.Frequency conversion speed-adjusting system is not extensive in the popularization that promotes in the class load.Its reason is an elevator, and particularly big capacity elevator requires too high to frequency converter, and frequency converter will double the above low-frequency torque of the above detent torque of nominal torque, 1.6 times of nominal torques, greater than the brake torque of nominal torque.In addition, also require four quadrant running.Because when weight is transferred, under the effect of gravity, the rotating speed of rotor may be greater than the rotating speed of stator rotating magnetic field, motor has become generator, regenerated energy raises busbar voltage, and must shift this part energy rapidly this moment, or feedback grid or fall with the power consumption resistance consumption.Current mining elevator multiple purpose aeroplane tool speed change or use the wire wound induction motor drive.The wire wound asynchronous electric motor speed adjusting method is rotor crosstalk resistance, this system belongs to step speed regulation, slip power is big, starting current and the gear shift rush of current is big, high speed operation vibrations are big, braking dangerous unreliable, to regenerated energy deal with improperly, speed governing in service is discontinuous slides down the failure rate height easily.Treating method to regenerated energy is a feedback grid, this yes good method, but because power network fluctuation is big, during Way of Regenerating Energy Feedback electrical network there is impact, in other words electrical network there is to a certain degree pollution, the original way of handling regenerated energy is a power consumption resistance, and this part energy is wasted, and this resistance burns out and require heat-dissipating space easily.
The utility model content: the purpose of this utility model is, overcome the deficiencies in the prior art part, a kind of storage device of regenerated energy is provided, select suitable capacity, suitable withstand voltage ultracapacitor memory for use as regenerated energy, after motor enters generating state, busbar voltage rises, and at this moment is busbar voltage to be descended the electric capacity charging.When the regenerative electric power process finishes, when busbar voltage falls back to safety value, allow big electric capacity to bus discharge, feed back to bus again and get on being stored in electric energy on the electric capacity, this is the basic scheme that regenerated energy stores.The storage device of a kind of regenerated energy described in the utility model includes two high frequency electronic switch devices, a large bulk capacitance and an inductance and forms.Three-phase electricity becomes direct current after by rectifier rectification filtering, and this direct current is reverse into needed three-phase electricity or single-phase electricity by inverter then, and Shu Chu three-phase electricity or single-phase electricity link to each other with load then.This device is mainly used in and is connected in parallel in this DC link.The connected mode of this device is as follows, the high frequency electronic switch device be connected in parallel on this DC circuit both positive and negative polarity after another high frequency electronic switch device is connected; Large bulk capacitance is with after inductance is connected, and links the negative pole of DC circuit at the other end of large bulk capacitance, links to each other with the series connection point of high frequency electronic switch device with another high frequency electronic switch device at the other end of inductance.
The storage device of a kind of regenerated energy described in the utility model can store regenerated energy, can utilize the regeneration energy stored more simultaneously, both can realize energy savings, can guarantee the normal operation of circuit and consuming device again.
Description of drawings: accompanying drawing is the regenerated energy storage schematic diagram of the storage device of a kind of regenerated energy described in the utility model.
Embodiment: referring now to accompanying drawing, be described as follows in conjunction with the embodiments: the storage device of a kind of regenerated energy described in the utility model includes two high frequency electronic switch devices (BT1 and BT2), a large bulk capacitance (C
B) and an inductance (L) composition.Three-phase electricity becomes direct current after by rectifier filter (U1), and this direct current is reverse into needed three-phase electricity or single-phase electricity by inverter (U2) then, and Shu Chu three-phase electricity or single-phase electricity link to each other with load (M) then.This device is mainly used in and is connected in parallel in this DC link.The connected mode of this device is as follows, high frequency electronic switch device (BT1) be connected in parallel on the anodal and negative pole of this DC circuit after high frequency electronic switch device (BT2) is connected on; Large bulk capacitance (C
B) with after inductance (L) is connected, at large bulk capacitance (C
B) the other end link the negative pole (-) of DC circuit, link to each other with the series connection point of high frequency electronic switch device (BT1) at the other end of inductance (L) with high frequency electronic switch device (BT2).The storage device of a kind of regenerated energy described in the utility model can store regenerated energy, can utilize the regeneration energy stored more simultaneously, both can realize energy savings, can guarantee the normal operation of circuit and consuming device again.
