The specific embodiment
Embodiment 1
Use Fig. 1 and Fig. 2 that an embodiment of the invention are described.Fig. 1 is the overall diagram of the elevator control gear of expression an embodiment of the invention.
In Fig. 1, elevator control gear has: the current converter 5 that three-phase alternating-current supply 3 is converted to vdc; Make the pulsating voltage of current converter 5 become level and smooth straight-though cond 7; The inverter that exchanges 10 with produced the variable voltage variable frequency by vdc also has by inverter 10 drive electric motor 17.
And inverter 10 constitutes according to moving from the command signal of elevator control part 40.
At the minus side of cond 7 is that the minus side of dc bus is connecting the emitter as the regenerated crystal pipe 31 of semiconductor switching module, positive side at dc bus, be connected backflow diode 33 and be connected in parallel as the regeneration resistance 35 of exothermic body with the collecting electrode of regenerated crystal pipe 31 via regeneration resistance 35.In addition, the anode of backflow diode 33 is connected with the positive side of dc bus, and negative electrode is connected with the collecting electrode of regenerated crystal pipe 31.Also can use the heater of induction type to replace regeneration resistance 25.
Connecting voltage detection department 51 on dc bus, it detects the vdc of current converter 5, and produces voltage detection signal, and the mouth of voltage detection department 51 is connected with the base stage of regenerated crystal pipe 31 via regeneration instructions portion 53.Regeneration instructions portion 53 constitutes predefined reference voltage signal (reference voltage value) and voltage detection signal is compared, if voltage detection signal surpasses reference voltage signal, then produce the regeneration instructions signal, make regenerated crystal pipe 31 become conducting by ending.
Two ends at regeneration resistance 35 are provided with: electric pressure converter 71, and it makes the chopping voltage of the being imported cunning that flattens, and produces the peaked vdc that is lower than chopping voltage simultaneously; Mouth bonded assembly electric power storage cond 73 with electric pressure converter 71; With cooling fan 75, its mouth with electric pressure converter 71 is connected, and to 35 air-supplies of regeneration resistance.Therefore, from the regenerated electric power increase of electrical motor 17, the both end voltage of regeneration resistance 35 raises, so the cooling power of cooling fan 75 improves.
The action of the elevator control gear that the explanation that sees figures.1.and.2 constitutes as mentioned above.Fig. 2 is the sequential chart of the action of expression elevator control gear shown in Figure 1.Now, when when moment t0 car 25 begins to descend under rated load, promptly produce regenerated electric power after a while, and charge by 10 pairs of conies 7 of inverter from electrical motor 17.Therefore, when the voltage at moment t1 dc bus rose, voltage detection department 51 detected the voltage of dc bus and produces voltage detection signal.Regeneration instructions portion 53 judges whether voltage detection signal surpasses reference voltage signal, produces the regeneration instructions signal when surpassing, and makes regenerated crystal pipe 31 by by becoming conducting, makes electric current flow through regeneration resistance 35, and consumes the regenerated electric power that is produced by electrical motor 17.
