Dab tsi yog vim li cas vim li cas lub qhov cub muaj qhov ci ntsa iab?

Thaum lub sij hawm ua hauj lwm ntawm industrial ncu, ntau yam malfunctions ib txwm tshwm sim. Yog tias tsis daws tau, txuas ntxiv siv lawv yuav ua rau cov cuab yeej puas lossis lwm yam cuam tshuam. Vim li cas nws thiaj li tso saib tsis tu ncua flashing? Hauv qab no, Hualubao yuav tshuaj xyuas cov laj thawj tshwj xeeb thiab kev daws teeb meem rau txhua tus.
Yog vim li cas rau industrial cub flashing. Kev ntsuas kub ntawm qhov ntsuas kub: qhov ntsuas kub: Lub ntsuas ntsuas vaj huam sib luag PV qhia qhov ntsuas kub tshwj xeeb hauv qhov cub, thiab SV qhia qhov ntsuas kub. Ua ntej, nias tus yuam sij SET, thiab SV qhia tus nqi flashing. Tom qab ntawd, nias tus yuam sij ▲ ntxiv kom qhov kub thiab txias, lossis nias tus yuam sij rho tawm kom txo qhov kub. Thaum kawg, nias tus yuam sij SET txhawm rau qhia qhov ntsuas kub uas koj tau teeb tsa, thiab SV qhia tias tus nqi yuav tsum tsis txhob flashing.
Kev daws teeb meem rau kev lag luam qhov cub flashing: Ua ntej xyuas yog tias lub caij nplooj ntoos hlav ncab ntawm lub tsheb relay ntawm lub qhov cub hluav taws xob tau poob; Puas yog qhov chaw tiv tauj "tua" thiab lo ua ke? Puas yog mercury kem hlau nyob rau hauv cov hluav taws xob tiv tauj tus pas ntsuas kub kawg tawg? Puas yog cov kab sib txuas txuas nrog tus pas ntsuas kub rau saum lub thawv ziab kom tawg, thiab lub taub hau puas muaj kev sib cuag tsis zoo? Siv lub tshuab digital multimeter los xyuas seb tus resistor R thiab R yog cov coj los yog qhov chaw welded. Ntsuas qhov tseeb ntawm 7-pin (grid voltage) ntawm lub raj rectifier Puas muaj qhov ua haujlwm voltage ntawm ib ncig ntawm 20V; Xyuas seb 7 tus pins ntawm lub rooj zaum lub raj puas muaj kev sib cuag zoo. Yog tias qhov kev ua txhaum tsis tau raug tshem tawm tom qab kev tshuaj xyuas thiab kev saib xyuas saum toj no, lub zog hloov pauv tseem ceeb tuaj yeem qhib thiab tawm ntawm tes. Xyuas seb qhov chaw tiv tauj ntawm lub tsheb relay tuaj yeem tso tau yooj yim thaum lub hwj chim hloov hluav taws xob raug kaw. Yog tias nws tsis tuaj yeem tso tawm tau yooj yim, nws yuav yog vim kev so mus sij hawm ntev thiab tsis muaj qhov ductility ntawm lub nraub qaum rub lub caij nplooj ntoos hlav vim cua sov, ua rau lub zog tiv tauj tsis tau rov qab tau yooj yim tom qab lub zog ntawm lub tsheb relay electromagnetic coil tig. tawm. Hauv cov xwm txheej zoo li no, lub zog tuaj yeem raug txiav tawm, tshem tawm cov mos txwv daj, thiab txiav ib ntu los sim nws; Yog tias nws tsis zoo, koj tuaj yeem hloov nws nrog cov ntaub nplaum daj tshiab los daws qhov teeb meem no.
Tshem tawm cov xwm txheej txawv txav hauv qhov cub muaj: Puas tsis muaj qhov qhia txog kev ua haujlwm tiag tiag ntawm lub tshuab hluav taws xob thaum tig lub zog hloov hluav taws xob? Thov xyuas yog tias peb-theem fais fab mov thiab xoom kab tau poob lawm. Yog lub hwj chim hloov hauv sab hauv yog disconnected. Puas yog lub fuse tube melting? Thov hloov nws nrog tus tshiab. R. Puas yog qhov xoom thiab nyob ntawm cov xov hlau S thiab T zoo ib yam, thiab puas muaj ib theem tawg? Thov hloov peb-theem fais fab mov.
Qhov kub nyob rau hauv qhov cub muaj tsis tau mus txog qhov preset tus nqi, thiab lub hwj chim mov raug txiav tawm! Yog hais tias lub fuse ntawm RD fuse raug hlawv tawm thaum lub sij hawm tag nrho cov txheej txheem cua sov, nws tuaj yeem ua rau qhov kev txhaum no thiab tsis tuaj yeem tsis quav ntsej. Tsis tas li ntawd, thaum lub qhov cub kom qhuav yog nyob rau hauv ib txwm ua haujlwm, hluav taws xob cua sov hlau R nyob rau hauv qhov cub thiab lub on-off ntawm lub switching fais fab mov yog tswj los ntawm hluav taws xob khoom xws li tsheb relays. Thaum ib qho kev txhaum tshwm sim hauv qee yam ntawm lub zog hluav taws xob (xws li resistor R lead), nws yuav ua rau cov khoom siv hluav taws xob hloov hluav taws xob poob tswj, ua rau qhov kub thiab txias tsis tu ncua, thiab yog li ua rau muaj kev txhaum ntau dua.
