Chitsanzo cha Zamalonda

CJ: Kodi ya kampani
M: Chotsukira ma circuit cha bokosi lopangidwa
1: Nambala ya Kapangidwe
□:Mawonekedwe amakono a chimango
□:Kutha kusweka kwa mphamvu/khodi ya khalidwe/S imasonyeza mtundu wokhazikika (S ikhoza kuchotsedwa)H imasonyeza mtundu wapamwamba

Dziwani: Pali mitundu inayi ya pole yosagwirizana (pole ya N) ya zinthu zinayi. Pole yosagwirizana ya mtundu wa A ilibe chotchinga chamagetsi chopitirira muyeso, nthawi zonse imayatsidwa, ndipo simayatsidwa kapena kuzimitsidwa pamodzi ndi pole zina zitatu.
Mzati wa mtundu wa B wopanda mphamvu uli ndi chinthu chogwetsa mphamvu zambiri, ndipo umayatsidwa kapena kuzimitsidwa pamodzi ndi zipilala zina zitatu (mzati wa neutral umayatsidwa usanazimitsidwe) Mzati wa neutral wa mtundu wa C uli ndi chinthu chogwetsa mphamvu zambiri, ndipo umayatsidwa kapena kuzimitsidwa pamodzi ndi zipilala zina zitatu (mzati wa neutral umayatsidwa usanazimitsidwe) Mzati wa neutral wa mtundu wa D uli ndi chinthu chogwetsa mphamvu zambiri, nthawi zonse umayatsidwa ndipo suyatsidwa kapena kuzimitsidwa pamodzi ndi zipilala zina zitatu.

Kugawa

• Mwa kuswa mphamvu: mtundu wokhazikika (mtundu S) b wapamwamba mtundu wa kuswa mphamvu (mtundu H)
• Mwa njira yolumikizira: kulumikizana kwa bolodi lakutsogolo, kulumikizana kwa bolodi lakumbuyo la b, mtundu wa pulogalamu yowonjezera ya c
• Pogwiritsa ntchito njira yogwirira ntchito: ntchito yogwirira mwachindunji, ntchito yogwirira yozungulira b, ntchito yamagetsi c
• Chiwerengero cha ndodo: 1P, 2P, 3P, 4P
• Ndi chowonjezera: kukhudzana ndi alamu, kukhudzana kothandizira, kutulutsidwa kwa shunt, kutulutsidwa kwa mphamvu yamagetsi

Mkhalidwe Wabwinobwino wa Utumiki

• Kutalika kwa malo okhazikitsa sikuyenera kupitirira 2000m
• Kutentha kwa mpweya wozungulira
• Kutentha kwa mpweya wozungulira sikuyenera kupitirira +40℃
• Mtengo wapakati suyenera kupitirira +35℃ mkati mwa maola 24
• Kutentha kwa mpweya wozungulira sikuyenera kuchepera -5℃
• Mkhalidwe wa mlengalenga:
• 1. Chinyezi cha mpweya sichiyenera kupitirira 50% pa kutentha kwakukulu kwa +40℃, ndipo chikhoza kukhala kutentha kwakukulu pa kutentha kochepa, pamene kutentha kotsika kwambiri pamwezi wonyowa kwambiri sikupitirira 25℃ kungakhale 90%, chifukwa cha kusintha kwa kutentha, ziyenera kuganiziridwa.
• Mlingo wa kuipitsa ndi kalasi 3

ZIKWANGWANI ZOGWIRITSA NTCHITO ZOCHOTSERA MALANGIZO (MCCB)

Mu MCCB, mphamvu yothyola ma circuit short breaking imatanthauza mphamvu yothyola ma circuit pansi pa mikhalidwe yodziwika. Pambuyo pa njira yoyesera yomwe yatchulidwa, ndikofunikira kuganizira kuti circuit breaker ikupitiliza kunyamula mphamvu yake yodziwika. Pofuna kukwaniritsa zosowa za ogwiritsa ntchito osiyanasiyana, opanga ma circuit breaker ambiri tsopano amagawa mphamvu yothyola ma circuit short-circuit ya shell rating current yomweyi m'magawo osiyanasiyana, ndipo ogwiritsa ntchito amatha kusankha circuit breaker yoyenera malinga ndi zosowa zawo kuyambira pa zochepa mpaka ma circuit breaker apamwamba kwambiri. Ndi ofala kwambiri ndipo amapezeka pafupifupi mnyumba iliyonse kapena nyumba iliyonse kotero kuti nthawi zambiri amaonedwa ngati osafunikira. Komabe, amachita gawo lofunikira mu dongosolo lathu lamagetsi ndipo ayenera kusamalidwa kuti agwirizane ndi miyezo yaposachedwa yachitetezo.

Ma MCCB amapereka yankho nthawi yomweyo ku mphamvu yamagetsi yafupipafupi, kutengera mfundo ya maginito amagetsi. MCCB ili ndi coil ya solenoid yomwe imapanga munda waung'ono wamagetsi pamene mphamvu yamagetsi imadutsa mu MCCB. MCCB imagwiritsa ntchito chipangizo chozindikira kutentha (chomwe chili ndi mphamvu yamagetsi) chokhala ndi chipangizo chozindikira magetsi chamagetsi (chomwe chili ndi mphamvu yamagetsi) kuti ipereke njira yoyendera (chomwe chili ndi mphamvu yamagetsi yamagetsi) kuti iteteze kutentha ndi kudzipatula. Pa nthawi ya ntchito yanthawi zonse kapena nthawi yanthawi zonse, mphamvu yamagetsi yopangidwa ndi coil ya solenoid ndi yochepa. Komabe, pamene vuto lafupipafupi lamagetsi lichitika mu dera, mphamvu yamagetsi yayikulu imayamba kuyenda kudzera mu solenoid ndipo, chifukwa chake, mphamvu yamagetsi yamphamvu imakhazikika yomwe imakopa mzere wolowera ndikutsegula zolumikizira.
