Zofunikira pa Kusintha Kwamagetsi Awiri Pakusintha Nambala Yapamtengo

Kaya mzere wosalowerera uyenera kudulidwa litikusinthapakati pa magetsi a thiransifoma ndi magetsi a jenereta (kuphatikiza kugwiritsa ntchitowapawiri mphamvu zodziwikiratu kutengerapo lophimba) zimatengera mikhalidwe kapena zinthu zingapo, kuphatikiza mtundu wa malo olumikizirana magetsi awiri, ngati malupu awiri amphamvu alumikizidwa ndi sam.e low-voltage switchboard, ndi momwe kukhazikitsira dongosolo kumakhazikitsidwa.Kaya dera lamagetsi lili ndi RCD kapena chitetezo chokhazikika cha gawo limodzi, ndi zina zotero, zinthu zimakhala zovuta kwambiri.Pachifukwa ichi, miyezo ya IEC sipanga makonzedwe omveka bwino.

Tiyeni tiwone masinthidwe osiyanasiyana amitundu iwiri:

1.Zigawo ziwiri zamagetsi zomwe zimayikidwa pamalo amodzi, ndikugawana zomwezootsika-voltage yogawa kabati, lupu lolowera kapena mphamvu ziwirikusintha kusinthaloop iyenera kugwiritsidwa ntchito4 pole transfer switch.

Tiyeni tiwone Chithunzi 1

Chithunzi 1

Kuchokera ku FIG.1, titha kuwona kuti ma RCD awiri otetezedwa3 ma pole circuit breakersQF11 ndi QF21 zimayikidwa kumapeto kwa zida zamagetsi kuti zigwirizane ndi magetsi awiri.Tikuganiza kuti QF11 yatsekedwa ndipo QF21 yazimitsa.
Titha kuwona kuti ngati vuto la gawo limodzi la gawo limodzi kapena kusalinganika kwa magawo atatu kumachitika mu zida zamagetsi, gawo limodzi lokhalokha lapansi kapena mzere wosalowerera ndale womwe umachitika chifukwa cha kusalinganika kwa magawo atatu ukhoza kudutsa mu mzere wa N ndi PE Chithunzi cha QF21.Chifukwa chitetezo cha QF21 RCD, QF21 chili muchitetezo chachitetezo, cholephera kutseka bwino.
Ndipo mosemphanitsa.Pachithunzi 1, zomwe zikuyenda mumzere wosalowerera ndale kapena PE mzere wa QF21 loop ndi mzere wosalowerera ndale wa njira yomwe si yachibadwa.Njira yomwe mzere wosalowerera ndale wa njira yosadziwika bwino umayenda ukhoza kupanga chipika chophimbidwa, ndipo mphamvu ya maginito yomwe imapangidwa mu chipika chophimbidwa imatha kusokoneza zida zachinsinsi, ndipo nthawi yomweyo zingayambitse wophwanya dera kuti agwire ntchito molakwika.Yankho lake ndikugwiritsa ntchito kusintha kwa quadrupole kwa QF11 ndi QF21 kuti mudule njira yomwe cholakwika chikuyenda.

2. Ma transfoma amtundu wapawiri ndi magetsi osungira wina ndi mnzake, kapena ma transfoma ndi ma jenereta a dizilo ndiwotengera mphamvu ya wina ndi mnzake, ndipo nsonga zopanda ndale za ma transfoma ndi ma jenereta zimakhazikika pafupi.Ngati ma seti awiri amagetsi agawana bolodi yotsika yamagetsi, loop yomwe ikubwera iyenera kugwiritsa ntchito masiwichi 4, monga momwe chithunzi 2 chikusonyezera.

Chithunzi 2

Kuchokera pa Chithunzi 2, titha kuwona kuti ma network otsika-voltage ogawa ndi mtundu wa tn-S, ndipo gawo losalowerera ndale la thiransifoma limakhazikika pafupi, kutsogolera magawo atatu, N line ndi mzere wa PE kuchokera ku transformer kupita ku low-voltage. gawo lobwera la kabati yogawa.Makina otsika-voltage omwe amalowa m'derali ndi ophwanyira mabasi ndi masiwichi atatu.Wowononga dera yemwe akubwera amakhala ndi chitetezo chokhazikika cha gawo limodzi.

Pogwiritsidwa ntchito mwachizolowezi, wowononga dera amatsekedwa ndipo busbar imatsegulidwa.Kuwonongeka kwa gawo limodzi kukakhala pazida zamagetsi m'basi ⅰ, titha kuwona kuti njira yolondola ili motere: chipolopolo cha zida zamagetsi → waya wa PE → kulumikizana kwa waya wa PE ndi waya wa N → gawo ⅰ N waya → Gawo ⅰ kuzindikiritsa zolakwika pakalipano → Gawo ⅰ chosinthira.

Njira iyi ndi yolondola.Chifukwa cha kusatsimikizika kwa mzere wa N ndi mzere wa PE wophatikizira malo, mwachitsanzo, mfundoyi ikhoza kukhazikitsidwa pazigawo ziwiri kukhala mzere wozungulira mzere, kotero kuti njira yosadziwika bwino ya gawo limodzi lokhazikika pakali pano ingakhale: kutsekera kwa zida zamagetsi. – PE line – Ⅱ mu mzere, PE line ndi N mzere kuphatikiza malo – Ⅱ nyengo ya N mzere – Ⅱ nthawi ya nthaka vuto panopa – Ⅰ nyengo ya N line – Ⅰ thiransifoma pansi zolakwika panopa – > Ⅰ ndime.Msewu womwe ukuyenda m'njirayi ndi njira yosalowerera ndale, yomwe ingayambitse ulendo wa ⅱ gawo lolowera, kupangitsa ngoziyo kukula.

Yankho lake ndi kugwiritsa ntchito aquadrupole switchkudula njira yosasinthika yomwe njira yolakwika imayenda ndikuchotsa zoopsa zobisika za ngozi.Momwemonso, ngati imodzi mwa ma thiransifoma isinthidwa ndi jenereta, jenereta yomwe ikubwera yamagetsi iyeneranso kugwiritsa ntchito chosinthira cha quadrupole.Kutsiliza: Pamene magetsi awiri ali m'chipinda chimodzi (pansi) ndikugawana kabati yogawa magetsi otsika, magetsi otsika a magetsi olowera ndi mabasi ayenera kugwiritsa ntchito 4 pole switch.

3. Ma seti awiri amagetsi ali m'chipinda chimodzi (malo wamba), koma sagawana kabati yogawa yotsika-voltage, kotero kutembenuka kwamagetsi mu zida zachiwiri zogawa kumatha kutengera 3 pole switch, monga momwe tawonera pa Chithunzi 3 .

Chithunzi 3

CHITH.3ATSEimatha kutengera masinthidwe atatu ngati ili ndi mphamvu yosungira.Kuchokera pa Chithunzi 3, titha kuwona kuti thiransifoma ndi jenereta zili pamalo omwewo otsika voteji, koma sagawana kabati yogawa voteji.Timawona kusalinganika kwa magawo atatu mu katundu wa woyendetsa dera QF11 wa zida zachiwiri zogawa, ndipo motero njira yosagwirizana ndi magawo atatu ikuwonekera mu mzere wosalowerera wa zida zamagetsi.

Njira ya magawo atatu osakhazikika pakali pano ndi awa: mzere wosalowerera ndale N mzati wa zida zamagetsi → mzere wosalowerera WA zida zachiwiri zogawira → mzere wosalowerera wa thiransifoma wogawa → kuzindikira kwapadziko lapansi cholakwika cha thiransifoma yomwe ikubwera loop → ndale mfundo N ya thiransifoma.Njira iyi ndi njira yokhazikika.

KuyambiraATSEndi unidirectional mu kutembenuka, akhoza kusankha pakati pa thiransifoma chakudya ndi jenereta chakudya, kotero ndale mzere panopa si kuonekera mu njira unconventional.Pankhaniyi, chosinthira cha ATSE chitha kugwiritsa ntchito chinthu chamitengo itatu.
