Description
Technical field
The present invention relates to a kind of checkout gear that dispatches from the factory automatically of frequency converter, relate to a kind of frequency converter that can control automatically checkout gear that dispatches from the factory.
Background technology
At present, for alternating current being changed into the frequency converter that direct current changes interchange again into, when dispatching from the factory, have following several to its method that whether can operate as normal detects:
(1) connect the actual induction motor that uses on detected frequency converter, perhaps the induction motor of model is dwindled in (2) connection, detects.
Also have in addition, (3) detect (example: refer to Patent Document 1) at the ac output end of detected frequency converter via insulating transformer connection PWM frequency converter.
What Fig. 4 represented is the pie graph of above-mentioned existing checkout gear (1) of dispatching from the factory.
In Fig. 4,40 are the detection control apparatus that dispatches from the factory, and 43 is detected frequency converter, and 44 for detecting motor, and 45 is coupler, and 46 are the load motor, and 47 are the load frequency converter.
The detection motor 44 that links to each other with detected frequency converter 43 is connected to load motor 46 by coupler 45, detects connected load frequency converter 47 on the motor 44 at this, and frequency converter 43 is manually controlled the detection of dispatching from the factory with frequency converter 47 by the detection control apparatus 40 that dispatches from the factory.
In the testing process,, make detected frequency converter 43 produce high voltage and high electric currents, detect the initial stage defective products thereby apply electrical load to the power semiconductor of detected frequency converter 43 inside by applying reverse moment of torsion from load motor 46 pairs of detection motors 44.
But this device is owing to adopt manual operation, and except that needs a large amount of detection times, the equipment investment of aspects such as control device and load equipment is huge, and need take bigger space.
In addition, the problem that has a trouble in the above-mentioned checkout gear that dispatches from the factory (2) in the past: owing to be to connect the induction motor that dwindles pattern to detect, event must be made the pattern of dwindling with actual induction motor and peripheral rotary body device equivalence at every turn separately, also must make sometimes and dwindle the frequency converter of pattern.
What Fig. 5 represented is the system diagram of the checkout gear (3) of patent documentation 1 record.
In the figure, the 100th, frequency converter checkout gear, the 110th, phase voltage detector, the 120th, insulating transformer, the 130th, choke, the 140th, DCCT, the 150th, PWM frequency converter, the 160th, direct current capacitor, the 201st, AC power, the 202nd, rectifier, the 203rd, frequency converter.PWM frequency converter 150 is made of switch 151～156 bridge joints that the diode with the switch element anti-parallel connection constitutes.
Among the figure, frequency converter 203 is by the switch control of built-in dc capacitor and PWM transducer, will export after exchanging power supply 201 and being converted to 3 cross streams electricity through the direct current of rectifier 202 inputs.
At this moment, the control circuit of frequency converter 203 is exported from the default rotation number generation circuit in the control circuit of frequency converter checkout gear 100 in input, during 3 phase currents of the default electrical angle speed omega r of induction motor and frequency converter 203 outputs, send the switching control instruction of the PWM transducer of equivalence when driving induction motors with frequency converter 203.
Frequency converter checkout gear 100 is made of phase voltage detector 110, insulating transformer 120, choke 130, DCCT140, PWM frequency converter 150, direct current capacitor 160.The positive pole of direct current capacitor 160 and negative pole import anodal with the direct current of frequency converter 203 respectively and negative pole is connected in parallel.
Like this, the ac output end of the frequency converter 203 of detected device is connected with PWM frequency converter 150 via insulating transformer 120, default electrical angle speed, reduce the differential equation number of times control PWM frequency converter 150 of induction motor, the phase current instruction of the frequency converter that the ac output voltage three of feasible electric fixed number according to induction motor that frequency converter drives, default electrical angle speed, frequency converter is calculated and the phase current of frequency converter equate.
Thus, insulating transformer and PWM frequency converter are equivalent to an induction motor that does not have rotary body, need not the equivalence of structure setting and carry out work.
