I. Cov Kev Xav Tau Ntawm Cov Hluav Taws Xob
1. Cov kab hluav taws xob zoo thiab Standardized
Cov kab hauv lub thawv yuav tsum zoo huv si thiab tsis muaj cov pob qij txha. Kev sib txuas ntawm cov hlau yuav tsum nruj, tsis muaj kev puas tsuaj rau cov tub ntxhais hlau lossis cov hlua tawg. Tus ntoo khaub lig- ntu ntu ntawm cov xov hlau nias ntawm ob sab ntawm cov ntsia hlau hauv qab lub tshuab ntxhua khaub ncaws yuav tsum zoo ib yam. Tsis pub ntau tshaj ob lub xov hlau yuav tsum txuas nrog tib lub tshuab hluav taws xob sib txuas. Anti-loosing washers thiab lwm yam yuav tsum ua kom tiav.
Txhua qhov hluav taws xob tiv thaiv kev sib txuas taw tes tau tso cai ntau kawg ntawm ob lub xov hlau. Feem ntau, ob lub xov hlau yuav tsum tsis txhob txuas mus rau txhua qhov chaw txuas ntawm lub davhlau ya nyob twg. Hauv cov xwm txheej tshwj xeeb uas ob lub xov hlau yuav tsum tau txuas nrog, qhov kev sib txuas yuav tsum txhim khu kev qha.
2. Tsis muaj qhov sib txuas hauv nruab nrab ntawm cov hlau
Yuav tsum tsis txhob muaj cov pob qij txha hauv nruab nrab ntawm cov xov hlau txuas. Hlau ceg pob qij txha yuav tsum tsis txhob bolted; lawv yuav tsum tau welded thiab insulated, tsis muaj qhov chaw nyob.
3. Kev kho cov hlau xaus
Lub stripped xaim yuav tsum tsis txhob ua rau cov hlau tseem ceeb heev. Hlau crimping yuav tsum ruaj thiab txhim khu kev qha. Multi-strand xov hlau yuav tsum tsis txhob coiled thiab crimped; crimping terminals yuav tsum tau ntsia. Yog hais tias crimping nrog lub teeb ntsia hlau yog tsim nyog, multi-strand xov hlau yuav tsum tau tinned ua ntej crimping; tus naj npawb ntawm strands yuav tsum tsis txhob raug txo.
4. Hlau Xim Xim
Cov xim cim ntawm cov xov hlau hauv lub thawv xa khoom yuav tsum tau sib txawv nruj me ntsis. Nyob rau hauv tsis muaj qhov xwm txheej yuav tsum muaj cov cim xim sib xyaw lossis hloov pauv.
Cov xim rwb thaiv tsev ntawm txhua hom xov hlau hauv tib lub tsev lossis cov qauv yuav tsum zoo ib yam. Hauv ib qho -theem 220V system, cov xaim nyob yuav tsum zoo dua yog xim liab, cov xaim nruab nrab xiav, thiab cov xaim hauv av daj-ntsuab.
II. Cov txheej txheem ntawm kev xa xov
1. N thiab PE Wire Configuration
Cov hluav taws xob mounting phaj ntawm lub thawv xa khoom yuav tsum muaj cais N thiab PE davhlau ya nyob twg thaiv.
Lub N davhlau ya nyob twg thaiv yuav tsum tau insulated los ntawm cov hlau hluav taws xob mounting phaj, thiab PE davhlau ya nyob twg thaiv yuav tsum tau hluav taws xob txuas rau hlau hluav taws xob mounting phaj.
N xaim nyob rau hauv cov kab nkag thiab tawm yuav tsum tau txuas nrog los ntawm N davhlau ya nyob twg thaiv, thiab PE hlau yuav tsum tau txuas los ntawm PE davhlau ya nyob twg thaiv.
Kev sib xyaw ntawm N thiab PE xov hlau raug txwv nruj heev.
N thiab PE xov hlau yuav tsum raug xa tawm los ntawm kev sib cais busbars thiab yuav tsum tsis txhob sib tw ua ke.
2. Cov Circuit Court sib txawv yuav tsum tsis txhob sib koom tib lub Terminal
N lossis PE cov xov hlau sib txawv ntawm cov kab hluav taws xob sib txawv yuav tsum tsis txhob txuas rau tib lub qhov lossis lub davhlau ya nyob twg ntawm lub tsheb npav. Tib lub davhlau ya nyob twg ntawm lub busbar yuav tsum tsis txhob txuas nrog N lossis PE cov xov hlau ntawm cov kab sib txawv.
3. Cov ntsiab lus ntawm Kev Siv Hluav Taws Xob
Tus naj npawb ntawm cov ntsiab lus txuas ntawm N- kab davhlau ya nyob twg thaiv thiab PE- kab davhlau ya nyob twg thaiv ntawm lub thawv loj (txheej txheem) yuav tsum yog n+1 (n- tus naj npawb ntawm circuits hauv lub thawv faib khoom); tus naj npawb ntawm cov ntsiab lus xaim ntawm N-kab davhlau ya nyob twg thaiv thiab PE- kab davhlau ya nyob twg thaiv ntawm sub- lub thawv xa khoom yuav tsum yog tsawg kawg ob; lub thawv hloov yuav tsum tau nruab nrog N- kab terminals thiab PE- kab terminals.
