Mzere wogawa wamagetsi otsika umatanthawuza mzere womwe umachepetsa mphamvu ya 10KV mpaka 380 / 220v kudzera mu transformer yogawa, ndiko kuti, mzere wochepa wamagetsi wotumizidwa kuchokera ku substation kupita ku zipangizo.

Mzere wogawa wamagetsi otsika uyenera kuganiziridwa popanga njira yolumikizira ma waya a substation.Kwa ma workshop ena omwe amagwiritsa ntchito mphamvu zambiri, msonkhanowu ulinso ndi kagawo kakang'ono ka transformer.Transformer imapereka mphamvu pazida zamagetsi, pomwe Kwa ma workshop okhala ndi mphamvu zochepa, magetsi amaperekedwa mwachindunji ndi chosinthira chogawa.

Njira yogawa mphamvu yamagetsi otsika

Mzere wogawa wamagetsi otsika umapangidwa ndikuyikidwa molingana ndi mtundu, kukula, kugawa ndi chikhalidwe cha katundu.Nthawi zambiri, pali mitundu iwiri yogawa, mtundu wa radial ndi thunthu, monga momwe zikuwonekera pachithunzi chakumanja.

Radial mizere ndi kudalirika wabwino, koma mkulu ndalama ndalama, kotero tsopano otsika-voteji mphamvu yogawa mawaya amagwiritsidwa ntchito thunthu mtundu, amene angapeze kusinthasintha zokwanira.Tekinoloje yopangira ikasintha, mzere wogawa sufunika kusintha kwakukulu.Mtengo wamagetsi ndi wochepa kwambiri, womwe ndi makhalidwe ake awiri akuluakulu.Inde, ponena za kudalirika kwa magetsi, sizili bwino ngati mtundu wa radial.

Mitundu ya mizere yogawa yotsika kwambiri

Pali njira ziwiri zoyikira mizere yochepetsera mphamvu yamagetsi, ndiyo njira yoyika chingwe ndi njira yoyakira pamzere.

Chifukwa chingwe cha chingwecho chimayikidwa mobisa, chimakhala ndi mphamvu zochepa zachilengedwe kunja, monga mphepo yamphamvu ndi icing, ndipo palibe mawaya omwe amawonekera pansi, motero amakongoletsa maonekedwe a mzinda ndi chilengedwe cha nyumbayo, koma ndalama zogulira. wa chingwe chingwe ndi mkulu, ndipo kukonza n'kovuta kwambiri., ubwino wa mizere yapamwamba ndi yosiyana.Choncho, m'malo opanda zofunikira zapadera, mawaya otsika kwambiri amatengera njira yodutsa pamwamba.

Mizere yocheperako nthawi zambiri imapangidwa ndi matabwa kapena mitengo ya simenti kuti apange mitengo yafoni, ndipo mabotolo adothi amagwiritsidwa ntchito kukonza mawaya pamikono yopingasa yamitengo.Mtunda pakati pa mitengo iwiriyi ndi pafupifupi 30 ~ 40M pabwalo, ndipo imatha kufika 40 ~ 50M pamalo otseguka.Mtunda pakati pa mawaya ndi 40-60 cm.Kuyimitsidwa kwa mzere ndi kwaufupi momwe ndingathere.Zosavuta kukonza ndi kukonza.

Bokosi logawa pamalo omanga

Mabokosi ogawa pa malo omanga akhoza kugawidwa m'mabokosi ogawa wamba, mabokosi ogawa okhazikika ndi mabokosi ogawa mafoni.

Bokosi logawa zonse:

Ngati ndi thiransifoma palokha, thiransifoma ndi waukulu kugawa bokosi pambuyo anaika ndi ofesi ya magetsi.Bokosi lalikulu logawa lili ndi chowotcha chamagetsi otsika kwambiri, ma watt ola limodzi, ma voltmeters, ma ammeters, ma switch switch, ndi magetsi owonetsa.Mawaya a nthambi iliyonse ya malo omangapo ayenera kulumikizidwa ku bokosi logawira nthambi kuseri kwa bokosi lalikulu logawa.Ngati ndi transformer yokhala ndi mitengo, mabokosi awiri ogawa amaikidwa pamtengo, ndipo ndege yapansi ya bokosi ili yoposa 1.3m kuchokera pansi.DZ mndandanda otsika-voltage circuit breakers amagwiritsidwa ntchito m'bokosi logawa.Chophwanyidwa chonse cha dera chimasankhidwa molingana ndi momwe ma transformer akuyendera.Mzere uliwonse wa nthambi umayendetsedwa ndi woyendetsa dera wokhala ndi mphamvu zochepa.Kuthekera kwa wowononga dera kumasankhidwa malinga ndi kuchuluka kwazomwe zikuchitika kuzungulira dera.Ngati yapano ndi yaying'ono, iyenera kukhala Sankhani chosinthira kutayikira (kuthekera kwakukulu kosinthira kutayikira ndi 200A).Chiwerengero cha ophwanya magawo ang'onoang'ono ayenera kukhala chimodzi kapena ziwiri kuposa kuchuluka kwa nthambi zomwe zapangidwa ngati nthambi zosunga zobwezeretsera.Bokosi logawa malo omanga silikhala ndi ma voltmeter apano komanso owunikira.

Ngati siwodziyimira pawokha, koma chosinthira choyambirira chimagwiritsidwa ntchito, bokosi lalikulu logawa ndi bokosi logawa la shunt limaphatikizidwa, ndipo ma watt-hour yogwira ntchito komanso yogwira ntchito amawonjezeredwa.Kuyambira pa bokosi lalikulu logawa, mzere wakumbuyo umatenga TN-S magawo atatu a waya wamagawo asanu, ndipo chipolopolo chachitsulo cha bokosi logawa chimayenera kulumikizidwa ndi chitetezo cha zero.

Bokosi logawa lokhazikika:

Chifukwa cha chingwe chamitundu yambiri chomwe chimayikidwa pamalo omanga, njira yopangira magetsi imatenga mtundu wa radial, ndipo bokosi lililonse logawa lokhazikika ndilomapeto a nthambi iyi, motero nthawi zambiri imayikidwa pafupi ndi zida zamagetsi zanthambi iyi.

Chigoba cha bokosi lamagetsi chogawira chokhazikika chimapangidwa ndi mbale yachitsulo yopyapyala, ndipo pamwamba payenera kukhala mvula.Kutalika kwa thupi la bokosi kuchokera pansi ndi kwakukulu kuposa 0.6m, ndipo chitsulo chachitsulo chimagwiritsidwa ntchito ngati kuthandizira mwendo.200 ~ 250A chokha chosinthira chachikulu, pogwiritsa ntchito masinthidwe otayirira anayi, mphamvu zake ndizokwera kwambiri zida zamagetsi zomwe zili m'bokosi, poganizira kusinthasintha, zitha kupangidwa molingana ndi zofunikira za zida zosiyanasiyana zomwe zimagwiritsidwa ntchito pomanga. , monga kulingalira kuti bokosi lirilonse likhoza kugwirizanitsidwa ndi nsanja ya nsanja kapena Welder.Zosintha zingapo za shunt zimayikidwa kuseri kwa chosinthira chachikulu, ndipo masiwichi otayikira mapole anayi amagwiritsidwanso ntchito, ndipo mphamvu imaphatikizidwa molingana ndi zomwe zida zamagetsi wamba.Mwachitsanzo, chosinthira chachikulu chimagwiritsa ntchito chosinthira cha 200A, chokhala ndi nthambi zinayi, ziwiri za 60A ndi 40A ziwiri.Doko lakumunsi la shunt switch liyenera kukhala ndi fusesi ya porcelain plug-in ngati malo olumikizirana odziwikiratu ndikugwiritsidwa ntchito ngati mawaya opangira zida.Doko lakumtunda la fusesi limalumikizidwa ndi doko lakumunsi la chosinthira chotayikira, ndipo doko lakumunsi lilibe kanthu pazolumikizira zida.Pakafunika, chosinthira cha gawo limodzi chiyenera kuikidwa m'bokosi, chokonzekera kugwiritsidwa ntchito ndi zida zagawo limodzi.

Monga mapeto a mzere wa nthambi, pofuna kulimbikitsa kudalirika kwa chitetezo cha mzere wosalowerera ndale.Kuyikanso pansi kuyenera kuchitika pabokosi lililonse losasinthika.

Waya atalowetsedwa m'bokosilo, mzere wa zero womwe ukugwira ntchito umalumikizidwa ndi bolodi la terminal, mzere wagawo umalumikizidwa mwachindunji ndi doko lakumtunda kwa chosinthira chotayikira, ndipo mzere woteteza ndale umapindika pa bawuti yoyambira pa chipolopolo cha. bokosi logawa ndikukhazikika mobwerezabwereza.Pambuyo pa bokosi logawa Mzere wa zero wachitetezo umalumikizidwa ndi bolt iyi.

Bokosi logawa la mafoni:

Mawonekedwe a bokosi logawa mafoni ndi ofanana ndi bokosi logawa lokhazikika.Zimagwirizanitsidwa ndi bokosi logawa lokhazikika ndi chingwe chosinthika cha rabara chokhazikika ndikusunthira kumalo pafupi kwambiri ndi zipangizo zamagetsi, monga kuchokera pansi kupita kumalo omangamanga.Palinso chosinthira chotsitsa m'bokosilo, ndipo mphamvu yake ndi yaying'ono kuposa ya bokosi lokhazikika.Chosinthira chagawo limodzi ndi soketi ziyenera kukhazikitsidwa kuti zipereke mphamvu yagawo limodzi pazida zamagetsi zagawo limodzi.Chigoba chachitsulo cha bokosi logawa chiyenera kulumikizidwa ndi chitetezo cha zero.
