Nyob rau hauv ib qho hluav taws xob Circuit Court, cov kev ua ntawm cov khoom yog tswj los ntawm ib tug thib ob tswj daim duab. Txhawm rau nkag siab thiab ua tiav daim duab thib ob, ib tus yuav tsum ua raws cov txheej txheem ib ntus los ntawm sab laug mus rau sab xis thiab los ntawm sab saum toj mus rau hauv qab.
Cov ntsiab lus ntawm Secondary Wiring Diagram
Cov kab hluav taws xob thib ob yog qhov hluav taws xob tsis tshua muaj hluav taws xob uas tsim los ntawm cov khoom siv thib ob. Nws suav nrog AC tam sim no Circuit Court, AC voltage Circuit Court, Circuit Court breaker tswj thiab teeb liab Circuit Court, relay tiv thaiv Circuit Court, thiab ib tug tsis siv neeg ntaus ntawv Circuit Court, thiab lwm yam. thiab cov ntawv cim. Nyob rau hauv kev ua hauj lwm, ib tug yuav tsum muaj kev nkag siab zoo ntawm cov kab hluav taws xob thib ob vim nws tau ntsib ntau zaus thiab muaj ntau daim duab.
Classification of Secondary Wiring Diagram
Daim duab kab txuas txuas ntxiv tuaj yeem muab faib ua ob pawg: schematic thiab kos duab kos duab. Schematics tau muab faib ua cov ntsiab lus schematic thiab unfolded schematic, thiab cov duab teeb tsa tau muab faib ua qhov screen layout thiab rov qab vaj huam sib luag thaiv daim duab.
(1) Schematic
Ib daim duab kab txuas txuas ntxiv uas qhia txog txoj haujlwm ua haujlwm yog hu ua schematic kos duab. Txij li cov khoom sib txawv muaj cov sawv cev sib txawv, schematics suav nrog:
a) Summary schematic, qhov twg txhua yam yog sawv cev raws li ib tug tag nrho nyob rau hauv daim duab, xws li cov duab sawv cev ntawm ib tug tam sim no relay. Lub kauj nyob rau hauv qab thiab cov neeg nyob rau saum toj yog siv los qhia txog DC Circuit Court.
b) Unfolded schematic yog qhov twg txhua feem yog decomposed rau hauv ob peb qhov chaw, xws li cais cov saum toj no-hais tam sim no relay mus rau hauv ib tug coil thiab kev sib cuag. Lawv tsis nyob ua ke hauv daim duab tab sis tau tawg nyob ib ncig ntawm lub voj voog uas muaj feem xyuam.
(2) Kev teeb tsa kev teeb tsa
Ib qho kev kos duab kos duab yog ib qho duab sawv cev ntawm qhov chaw tshwj xeeb thiab cov txheej txheem thaiv ntawm cov khoom siv thib ob raws li kev teeb tsa thiab kev tsim kho.
Kev teeb tsa kev teeb tsa muaj xws li ib qho screen layout thiab lub vaj huam sib luag thaiv kab rov tav. Hauv qhov screen layout, qhov loj thiab qhov nrug ntawm txhua qhov yuav tsum tau nthuav dav kom yooj yim rau kev teeb tsa. Lub vaj huam sib luag thaiv kab rov tav ntxiv cov lej rau txhua qhov sib xyaw thiab cov khoom siv hluav taws xob, thiab thaum txuas hauv kev tsim kho, nws tuaj yeem txuas nrog cov lej, uas yooj yim heev.
** Cov Cim Ntxim Saib Ntxim Saib Ntxim Ua hauv Cov Kabmob Thib Ob **
Nyob rau hauv daim duab thib ob, los qhia txog qhov xwm txheej ntawm kev sib txuas ntawm txhua qhov, txhua qhov yuav tsum tau sawv cev los ntawm cov cim duab thiab cov ntawv cim nrog cov yam ntxwv tshwj xeeb kom tsis txhob muaj kev ntxhov siab. Piv txwv li, cov ntawv cim rau lub relay tam sim no yog LJ, cov ntawv cim rau lub sij hawm relay yog SJ, cov ntawv cim rau lub pob xeem yog YA, cov ntawv cim rau lub pob pib yog QA, thiab cov ntawv cim rau nres pob yog TA.
Summary Schematic
Summary schematics feem ntau abbreviated li schematics. Txij li thaum cov khoom siv tau sawv cev rau tag nrho, lawv yooj yim to taub thiab tuaj yeem kos ua ke nrog cov cuab yeej tseem ceeb, ua kom yooj yim rau kev nkag siab txog lawv cov kev sib raug zoo thiab kev ua, uas yog qhov zoo rau kev piav qhia txog kev khiav hauj lwm hauv paus ntsiab lus. Qhov tsis zoo ntawm daim duab kab hluav taws xob no yog tias thaum muaj ntau cov khoom sib txuas, kev sib txuas tuaj yeem ua tsis zoo. Cov khoom siv terminals thiab cov xov hlau tsis muaj npe, thiab kev siv feem ntau tuaj yeem tsis yooj yim.
Tshaj tawm Schematic
Unfold schematics tseem hu ua unfolded daim duab, thiab lawv tau kos tag nrho rau hauv lwm daim ntawv. AC Circuit Court thiab DC Circuit Court yog cais nyob rau hauv daim duab unfolded. Hauv AC Circuit Court, nws muab faib ua AC tam sim no Circuit Court thiab AC voltage Circuit Court.
Nyob rau hauv daim duab unfolded, lub kauj thiab cov neeg sib txuas ntawm cov relay raug cais thiab sau nrog cov cim thiab cov ntawv sau, ua rau nws yooj yim los tso saib lawv cov haujlwm. Txhua lub voj voog yog teem los ntawm sab laug mus rau sab xis thiab sab saum toj mus rau hauv qab nrog cov nyees khawm, hu, thiab coil raws li cov kev taw qhia ntawm cov hluav taws xob tam sim no, ua kom tiav daim duab nthuav dav. Sab xis ntawm daim duab suav nrog cov lus piav qhia txog kev ua haujlwm ntawm lub voj voog, uas pab ntxiv rau kev nkag siab txog cov txheej txheem ua haujlwm ntawm lub voj voog. Txij li thaum daim duab nthuav dav yog kev ua kom zoo thiab yooj yim rau kev txheeb xyuas thiab txheeb xyuas, nws yog siv ntau tshaj plaws hauv kev ua haujlwm.
Screen Layout
Screen layouts yuav tsum ua tau raws li cov cai hauv qab no:
1. Cov cuab yeej thiab cov relays uas yuav tsum tau saib xyuas tas li yuav tsum tsis txhob teem caij siab dhau.
2. Qhov siab ntawm cov khoom siv ua haujlwm, xws li cov khoom tswj, tswj cov keyboards, thiab cov nyees khawm, yuav tsum nyob nruab nrab, thiab ib qho kev ncua deb yuav tsum tau khaws cia ntawm lawv kom tsis txhob cuam tshuam cov khoom nyob ib sab thaum ua haujlwm.
3. Rau cov cuab yeej siv uas yuav tsum tau kuaj xyuas thiab kuaj,
