Kev nyab xeeb Circuit Court
Muaj nuj nqi: Txhawm rau kom muaj kev nyab xeeb ntawm lub elevator, ntau yam kev nyab xeeb raug teeb tsa ntawm lub elevator. Tsuas yog thaum txhua qhov kev tiv thaiv kev nyab xeeb nyob rau hauv ib txwm muaj lub elevator tuaj yeem ua haujlwm, txwv tsis pub lub elevator yuav nres tam sim ntawd.
Lub npe hu ua kev nyab xeeb Circuit Court yog hais txog kev teeb tsa kev hloov pauv kev nyab xeeb hauv txhua qhov kev nyab xeeb ntawm lub elevator, uas txuas txhua qhov kev nyab xeeb hloov pauv hauv koob los tswj kev nyab xeeb relay. Tsuas yog thaum txhua qhov kev nyab xeeb hloov pauv tau qhib thiab qhov kev nyab xeeb relay qhib tau lub elevator tuaj yeem siv rau kev ua haujlwm.
Common kev ruaj ntseg circuits xws li:
Tshuab chav: tswj vaj huam sib luag thaum muaj xwm ceev nres hloov, theem ib theem relay, thermal relay, ceev limiter hloov
Hoistway: Kev hloov pauv sab saud thiab qis qis hloov pauv (qee lub elevator tso ob lub keyboards no rau hauv kev nyab xeeb Circuit Court, thaum lwm tus siv ob lub keyboards ncaj qha los tswj lub zog hluav taws xob)
Pit: txoj hlua tawg tiv thaiv kev hloov, qhov chaw tu lub thawv thaum muaj xwm ceev nres hloov, tsis hloov
Sab hauv lub tsheb: Kev kub ceev nres ntawm lub thawv tswj
Tsheb ru tsev: kev ruaj ntseg qhov rais hloov, kev nyab xeeb iav hloov, tsheb ru tsev tu lub thawv thaum muaj xwm ceev nres hloov
Fault status:
Thaum lub elevator nyob rau hauv lub xeev nres, tag nrho cov teeb liab tsis tuaj yeem sau npe, thiab ob qho tib si ceev thiab qeeb tsheb ciav hlau khiav tsis tau, nws xav tias qhov kev ruaj ntseg Circuit Court yog faulty. Koj yuav tsum mus rau qhov kev tshuaj ntsuam xyuas hauv chav computer kom saib xyuas qhov xwm txheej ntawm kev nyab xeeb relay. Yog hais tias qhov kev ruaj ntseg relay nyob rau hauv lub xeev tso tawm, nws yuav tsum tau txiav txim raws li ib tug kev ruaj ntseg Circuit Court txhaum.
Tej yam ua tau ntawm kev ua haujlwm tsis zoo:
1. Cov theem ua ntu zus yuam kev lossis tsis muaj theem ntawm cov khoom siv hluav taws xob ua rau cov theem ua ntu zus relay ua haujlwm.
2. Lub elevator ua haujlwm nyob rau hauv overload lossis kaw lub sijhawm ntev, ua rau lub thermal relay ua haujlwm.
3. Nws muaj peev xwm hais tias qhov overspeed ntawm qhov ceev limiter yuav ua rau lub nrawm limiter hloov mus ua.
4. Qhov txwv kev hloov pauv yog tshwm sim los ntawm lub elevator tsoo rau saum lossis tog hauv qab.
5. Txoj hlua khi txoj hlua tawg ua haujlwm. Tej zaum nws yuav yog vim tus tswv xeev txoj hlua dhia tawm los yog ntev dhau lawm.
6. Kev nyab xeeb iav ua haujlwm. Qhov laj thawj yuav tsum raug txheeb xyuas. Tej zaum nws yuav yog vim qhov kev txiav txim siab dhau ntawm tus tswv xeev ceev, kev ua haujlwm tsis raug ntawm tus tswv xeev nrawm vim poob roj, poob roj ntawm lub qhov hlua rub, cov khoom txawv teb chaws (xws li nas) tau nkag mus rau hauv lub qhov hlua rub, thiab me me dhau ntawm kev ruaj ntseg thaiv.
7. Lub qhov rais kev nyab xeeb yog nqa los ntawm ib tus neeg, ua rau lub qhov rais kev nyab xeeb hloov mus ua haujlwm.
8. Qee qhov chaw nres tsheb thaum muaj xwm ceev yuav raug nias los ntawm ib tug neeg.
9. Yog tias txhua qhov hloov pauv zoo li qub, xyuas seb lawv cov ntsiab lus tiv tauj puas zoo thiab yog cov xaim xoob xoob.
Tsis tas li ntawd, txawm hais tias kev nyab xeeb Circuit Court ntawm ntau lub elevator yog qhov qub thiab kev ruaj ntseg relay kuj tseem koom nrog, ib khub ntawm cov neeg sib tham feem ntau yog coj los ntawm kev nyab xeeb relay thiab xa mus rau microcomputer (lossis PC) rau kev sim. Yog hais tias qhov kev ruaj ntseg relay nws tus kheej muaj kev sib cuag tsis zoo, nws kuj tuaj yeem ua rau muaj kev ua haujlwm tsis zoo hauv kev nyab xeeb.
