Brief description
Fig. 1 is the circuit diagram of the supply unit of one embodiment of the present invention.
Detailed description of the invention
Hereinafter, referring to the drawings, embodiments of the present invention are described in detail.
The supply unit of embodiments of the present invention is to have towards as elevator and/or escalator etc.
The supply unit of the equipment of the motor of the driving of standby regeneration operating.Hereinafter, Fig. 1 is utilized to carry out in detail
Explanation.
As it is shown in figure 1, this supply unit 10 has the 11st, accessory power supply portion 12 of main power source portion and control
Circuit part 13 processed.Main power source portion 11 has the alternating electromotive force from source power supply 15 is transformed to direct current
The capacitor 17 of the converter 16 of electric power and filtering and this direct current power is inversely transformed into alternating current
The converter 18 of power.Further, the exchange output from this converter 18 is supplied to the horse driving
Reach 19.In the present embodiment, motor 19 is set to the driving use of not shown escalator.
Accessory power supply portion 12 has battery 20.This battery 20 is via the DC/DC of charge and discharge control
Converter 21 is connected with the DC circuit in main power source portion 11, is charged via DC/DC converter 21
The regenerated electric power being produced by the regeneration operating of motor 19.When motor 19 carries out power running, this electricity
Pond 20 is via the DC circuit in DC/DC converter 21 and main power source portion 11 and then via converter
18 carry out auxiliary power supply to motor 19.
It is provided with on circuit as load detecting portion performance work( supplying from main power source portion 11 to motor 19
The current detector 23 of energy, to the current value (load capacity) supplying to motor 19 from main power source portion 11
Detect.In addition, be provided with the surplus test section 24 detecting its surplus at battery 20.As this
Surplus test section 24, uses the device arranging at battery 20 study plot.
In addition, be provided with converter 26 and the electricity of filtering on the DC circuit in accessory power supply portion 12
Container 27, is configured to control circuit portion 13 supply control power supply.Control circuit portion 13 and business
Connect with the both sides in power supply 15 and accessory power supply portion 12, from source power supply 15 and accessory power supply portion 12
Either one can accept control power supply.Therefore, it is also able to maintain that control when source power supply 15 has a power failure
Function processed.
The escalator installation to application motor 19 for the control circuit portion 13 is integrally controlled, certainly,
Also the power running and regeneration operating of motor 19 is controlled.Therefore, from current detector 23 to
Control circuit portion 13 inputs the current value (load capacity) of flowing in motor 19, and from surplus inspection
Survey portion 24 inputs the surplus of battery 20 to control circuit portion 13.
In addition, in control circuit portion 13, corresponding with the surplus of battery 20, and set relative to
Motor 19 supply total electricity, from battery 20 electric power auxiliary ratio.Additionally, to motor 19
The total electricity of supply is obtained according to the current value inputting from current detector 23.This control circuit portion
13 examined according to the current value (load capacity) being detected by current detector 23 and by surplus detector 24
The surplus of the battery 20 measuring, determines the surplus corresponding electric power auxiliary ratio with the battery 20 detecting
Example.Then, control is from the electric power of battery 20 auxiliary power supply, so as to this electric power determined is auxiliary
Help ratio.That is, by DC/DC converter 21, the output power from battery 20 is controlled.
Here, (the electricity of the power supply ratio from battery 20 when the surplus of battery 20 and auxiliary power supply
Power assist ratio) relation set as following table.
Table 1
In addition, battery 20 be configured to the escalator with motor 19 beyond other equipment 30
Between, carry out electric power via the power converter portion 31 towards other equipment and give and accept.For example, by other
In the case that equipment 30 is set to elevator, regenerated electric power that the regeneration operating by elevator is produced via
Power converter portion 31 supplies to battery 20, is charged battery 20.In addition, at battery 20s
In the case of fully charged state, supply to the elevator as other equipment 30 via power converter portion 31
To electric power.
Additionally, be provided with the feelings of solar power plant in the building be provided with escalator installation
Under condition, it is also possible to be configured to the generation power of this solar power plant via power converter portion 31
Supply to battery 20, battery 20 is charged.
In said structure, in escalator, as is known, the load when declining operating (is taken advantage of
Visitor's number) when being more than predetermined value, motor 19 becomes regeneration operating, produces regenerated electric power.This regeneration electricity
Power is supplied to the DC circuit in main power source portion 11 via converter 18.It is supplied to this DC circuit again
Raw electric power is blocked by converter 16, so source power supply 15 side will not be flowed to, but from accessory power supply
The DC circuit in portion 12 supplies to battery 20 via DC/DC converter 21, carries out battery 20
Charging.
On the other hand, when the rising of escalator operates, motor 19 becomes power running, its load
Change because of load (ridership).That is, if load (ridership) is many, load big, then to motor
The electric power (current value) of 19 supplies also becomes big.When this power running, except from source power supply 15
Electric power outside, also carry out auxiliary power supply from battery 18.
Now, according to the surplus of battery 20, control circuit portion 13 determines that electric power set in advance assists
Ratio.For example, if battery allowance is big, then assisting ratio according to table 1 electric power set in advance is 50%,
Therefore this value is used.Then, DC/DC converter 21 is controlled, so that from the electricity of battery 20 supply
The ratio of power with respect to the current value (load capacity) being detected by current detector 23 obtain to
The supply electric power of motor 19 overall (total electricity) becomes the ratio of 50%.
Certainly, when source power supply 15 has a power failure, it is also possible to be configured to the battery from accessory power supply portion 12
Supply the electric power of 100% to motor 19, thus maintain the operating of escalator.
Additionally, the load capacity test section of the load capacity as detection motor 19, if motor 19 is automatic
Staircase drives use, then also can use at the image of the not shown ridership that can detect escalator
Reason device.That is, can obtain according to the ridership detecting and put on the load capacity of motor and right with it
The total amount of power answered
So, owing to being configured to arrange accessory power supply portion 12, regenerated electric power is filled with to this battery 20,
When power running, the electric power being filled with battery 20 is carried out auxiliary power supply, it is possible to suppression is from business
With the consumption electric power of power supply.Now, the load capacity of motor 19 and the surplus monitoring battery 20 are detected,
From electric power auxiliary ratio set in advance, select and determine the ratio of the surplus being most suitable for battery 20.So
After, control the supply electric power from battery 20, so that obtain with respect to the load capacity of motor
Total electricity, electric power auxiliary ratio become determined by ratio.Therefore, it is possible to with battery allowance phase
The certain ratio adapting to carries out auxiliary power supply.
Although being illustrated some embodiments of the present invention, but these embodiments are only used as example
Son and propose, be not intended to invention scope be defined.The embodiment of these novelties can be with
Other various forms are implemented, and can carry out various in the range of without departing from the main idea invented
Omit, replace, change.These embodiments and/or its deformation are contained in scope and/or the main idea of invention,
And it is contained in the invention described in claims and the scope with its equalization.
