Theem Sequence Meter Wiring Measurement Method thiab Phase Poob Teeb meem
Rau txoj kev ntsuas kev sib txuas ntawm cov theem ib ntus ntsuas thiab qhov teeb meem ntawm qhov tsis muaj theem, txuas peb qhov kev xeem coj ntawm cov theem ib ntus meter mus rau peb kab ntawm qhov chaw yuav tsum tau ntsuas, thiab siv qhov tseeb ntawm qhov tsis muaj theem qhia thiab theem ntu ntu qhia, thiab lwm yam. Ua ntej qhib rooj plaub, Nco ntsoov txiav tawm lub hwj chim.
Phase sequence tablewiring Measurement method
1. Cov kab hluav taws xob
Txuas peb txoj kab kev xeem A (liab, R), B (xiav, S), thiab C (dub, T) ntawm theem kab lus rau peb kab A (R), B (S), thiab C (T ) ntawm qhov chaw yuav tsum ntsuas, feem. hauv online.
2. Kev ntsuas
Nias lub ntsuas khawm nyob rau sab laug ces kaum ntawm lub 'meter', lub teeb yog nyob rau, thiab ntsuas pib. Kev ntsuas nres thaum lub ntsuas khawm tso tawm.
3. Phase poob qhia
Peb lub LEDs liab A, B, thiab C ntawm lub vaj huam sib luag qhia qhov sib txuas peb-theem hu xov tooj. Thaum ntsuas qhov chaw tawm ntawm theem, cov LED sib txuas tsis teeb.
4. Phase sequence indication
Thaum qhov peb-theem sib lawv liag ntawm qhov chaw nyob rau hauv kev ntsuam xyuas yog lawm, lub teeb ntsuab coj mus rau lub zoo theem ib theem zuj zus; Thaum peb-theem ib ntus ntawm qhov chaw nyob rau hauv qhov kev sim tsis raug, lub teeb liab sib raug rau qhov rov qab theem ib ntus yog nyob rau, thiab lub buzzer suab lub tswb.
Note 1: Positive phase sequence means UA0, UB0, UC0 (or UAB, UBC, UCA) lag by 120 degrees in sequence; rov qab theem ib ntus txhais tau tias UA0, UB0, UC0 (los yog UAB, UBC, UCA) coj los ntawm 120 degrees hauv ib ntus.
Lus Cim 2: Txhawm rau hloov cov theem rov qab mus rau theem zoo, tsuas yog pauv ob ntawm peb cov xov hlau A, B, thiab C.
Nco tseg: Thaum twg ib qho ntawm peb-theem cov kab nkag tau txuas nrog hluav taws xob, lub ntsuas hluav taws xob raug them. Nco ntsoov txiav tawm lub hwj chim ua ntej qhib rooj plaub.
1. Powered ncaj qha los ntawm lub hwj chim mov nyob rau hauv kev sim, tsis muaj roj teeb yuav tsum tau.
2. Nrog rau theem poob qhov taw qhia muaj nuj nqi: peb lub teeb liab-emitting diodes A, B, thiab C ntawm lub vaj huam sib luag qhia qhov sib txuas peb-theem hu. Thaum ntsuas qhov chaw tawm ntawm theem, qhov sib thooj LED tsis teeb.
3. Siv lub suab thiab lub teeb raws li theem qhia ua ntu zus: thaum qhov peb-theem ib ntus ntawm qhov chaw nyob rau hauv kev sim yog raug, lub teeb ntsuab sib raug rau theem zoo ua ntu zus; thaum peb-theem ib theem zuj zus ntawm qhov chaw nyob rau hauv qhov kev ntsuam xyuas yog tsis ncaj ncees lawm, lub teeb liab coj mus rau lub rov qab theem ib theem zuj zus. Lub teeb yog qhib thiab lub buzzer suab tswb.
