Yuav hloov thiab kho li cas kub hluav taws xob rauv thyristor?

Hloov Hloov Hloov Lub thyristor chav tsev, thawj zaug cais cov hluav taws xob kub kub ntawm lub tshuab hluav taws xob, thiab tom qab ntawd tshem tawm sab laug cover (0). Sau tag nrho cov kev sib txuas rau thyristor, thiab tom qab ntawd txiav nws. Hloov lub cuab yeej, thiab tom qab ntawd rov ua dua.

Lus Cim: Yog tias koj hloov 208V fais fab mov, koj yuav tsum hloov lub thyristor chav tsev.

Yog tias chav tsev thyristor hloov pauv vim qhov hloov pauv hloov pauv, qhov hloov pauv hloov kais kom raug yuav tsum tau teeb tsa. Tom qab hloov ib qho thyristor chav tsev, lossis tom qab hloov qhov voltage lossis transformer kais, lub potentiometer ntawm lub thyristor yuav tsum tau kho kom muab cov khoom raug tam sim no. Qhov kev ua haujlwm no yuav tsum tau ua los ntawm cov neeg ua haujlwm tsim nyog, vim tias muaj kev phom sij txaus ntshai nyob hauv chav tswj.

Tsis tas li ntawd, yuav tsum tau calibrated non-intrusive clamp ammeter. Ua ntej txuas lub hwj huam mov, tig lub potentiometer ntawm lub thyristor mus rau sab laug (counterclockwise). Qhov no teev cov zis tam sim no ntawm thyristor rau “tawm”. Txuas lub zog thaum kaw lub hau sab. Ceev faj! Teem lub qhov cub kub kom muaj nuj nqis loj. Cia lub qhov cub pib cua sov. Ntsuas qhov tam sim no los ntawm cov khoom siv hluav taws xob. Thaum ntsuas, siv cov tuab ntawm cov hlua ntawm sab laug ntawm lub tshuab hloov pauv kom cua lub clamp ammeter. Kho lub potentiometer nyob rau saum npoo ntawm chav tsev thyristor. Maj mam hloov mus rau sab xis (clockwise) kom nce qhov tam sim no, thiab nres kom lub ammeter teb.

Txuas ntxiv mus kho kom qhov kev nyeem ntawv ammeter nyob nruab nrab ntawm (149 txog 150 A-rau HTF 17) lossis (139 txog 140A-rau HTF 18). Qhov kev hloov kho no yuav tsum tau ua nyob rau hauv thawj 5 feeb ntawm cua sov, thiab qhov kev ntsuam xyuas zaum kawg yuav tsum tau ua thaum qhov kub ntawm lub qhov cub hluav taws xob kub kub qis dua nws qhov kub siab txog li 100 ° C. Yog tias tsim nyog, txuas ntxiv kho raws li qhov ntsuas kub no. Tshem tawm cov khoom siv hluav taws xob thiab nco ntsoov hloov lub vaj huam sib luag sab.
