Lub Ceg Txheem Ua Si Tester yog qhov ntsuas ntsuas ntsuas tshwj xeeb thiab tsim raws cov qauv xws li GB4207 thiab IEC60112. Nws yog qhov haum rau kev sim cov cabilage ncua sij hawm ntsuas thiab cov khoom siv hluav taws xob, khoom siv hluav taws xob ntawm cov khoom siv hauv tsev. Nws yog qhov yooj yim, raug, txhim khu kev qha thiab ua tau. Nws yog siv rau kev tshawb nrhiav, kev tsim khoom ntawm cov cuab yeej siv teeb pom kev zoo, tshuab hluav taws xob, cov cuab yeej hluav taws xob, cov tshuab hluav taws xob, khoom siv thev naus laus zis. Nws tseem haum rau insulating cov ntaub ntawv, engineering uas tshuab ua kom haum rau cov khoom siv hluav taws xob thiab simulation kev xeem hauv kev lag luam ntxiv.
Kev Xeem Cov Ntsiab Cai: Qhov kev sim taug kev taug qab yog thov ntawm ib qho kev sib tw ntawm cov khoom siv tsis zoo (0.1% NH 4Cl) ntawm qhov siab ruaj khov (35 hli ) Thiab lub sijhawm ruaj khov (30s) ntawm qee cov khoom siv hluav taws xob, thiab cov khoom siv ntub dej ntawm cov ntawv sau ua ke hauv qab (CT1) thiab to taub 010- 10
Cov kev xeem yuav tsum tau: Qhov kev laus tag nrho thiab kuaj ntawm lub chaw tswj hwm tsheb tswj lub tsheb (suav nrog kev xa khoom, fuses, thiab kab hlau txuas ntxiv).
1) Cov yam ntxwv tsis sib xws ntawm cov relay ntawm cov programmammable tower tam sim no tester
Thov saib cov ntawv ntsuas sib ntsuas. Cov cuab yeej kuaj xyuas cov yam ntxwv ntawm cov relay hauv lub xeev tsis muaj kev tswj hwm. Daim npav tswj Relay yog nyob rau hauv lub xeev tsis tswj, thiab qhov tsis kam ntawm lub ntsiab tswj choop yog txiav txim thiab cov nqi raug txiav txim;
Cov programmab siv thim cov neeg ua haujlwm tam sim no uas lub thauj khoom tam sim no cov tswj hwm hluav taws xob tseem ceeb tsawg dua li qhov tseem ceeb (xau tam sim no).
2) Xa mus rau tus qauv ntsuas sib nug rau cov yam ntxwv uas kaw ib txwm muaj ntawm cov relay.
Cov yam ntxwv ntawm relay nyob rau hauv lub kaw-voj tswj cov khoom siv ntawm cov khoom relay. Lub teeb liab tswj ntawm lub relay nyob rau hauv lub channel tshwj xeeb raug kaw rau hauv cov nplai loj (kev tswj hwm yog qhov loj heev lossis cov hluav taws xob tsawg lossis lub zog hluav taws xob yog qhov tsis raug);
Txiav txim siab tias qhov hluav taws xob poob qis ntawm cov tswj hwm hluav taws xob (qhov ntsuas hluav taws xob poob qis dua (kev tswj voltage tau loj dhau lossis qis dua lossis lub pob zeb tsis sib haum Ntawm lub Circuit Court tsis cuam tshuam rau cov voltage poob kev sim ua tiav: txiav txim siab tias lub thauj khoom tam sim no ntawm lub voj pib tam sim no yog nyob rau hauv cov nplai seem.
3) Xa mus rau tus qauv xeem sib xws rau kev tswj hwm cov yam ntxwv ntawm cov relay, thiab ua kev ua haujlwm txiav tawm ntawm cov relay.
Disconnect Cov channel tshwj xeeb relay tswj teeb liab, thiab txiav txim tias tus txiav txim tias kev tiv thaiv ntawm lub ntsiab tswj cheop voj yog tsawg dua li cov nqi teeb; Lub thauj khoom tam sim no tsawg dua li teev tus nqi (xau tam sim no).
4) Thov saib tus qauv ntsuas sib piv rau kev hloov kho ntawm qhov hluav taws xob ntawm cov relay tswj lub davhlau ya nyob twg.
Thaum lub kaw lus nres khiav, nws tuaj yeem tswj cov voltage thiab tam sim no ntawm cov pab hluav taws xob fais fab. Cov khoom siv fais fab muaj peev xwm tuaj yeem hloov kho rau qhov hluav taws xob ntawm 0-30V los pab txhawb kev sim ntawm kev tswj cov yam ntxwv ntawm cov relay.
Yog tias tsim nyog, cov khoom siv fais fab uas tuaj yeem hloov. Thaum kho tau thiab hloov lub zog hluav taws xob, thov them nyiaj rau kev tswj voltage nplai thiab ua haujlwm thov kev sim relay.
