Kuphatikizika kwa thiransifoma (yomwe imadziwikanso kuti kusintha kwa bokosi la ku America), monga gawo lofunikira lamagetsi pamaneti ogawa chingwe, chinthucho chimayika chosinthira chamagetsi champhamvu kwambiri komanso fuse yamagetsi apamwamba mu nduna ya thiransifoma.Tanki yamafuta imatenga mawonekedwe osindikizidwa bwino, ndipo mafuta osinthira omwe ali m'bokosi ali ndi ntchito yabwino yotchinjiriza komanso kutulutsa kutentha.Zili ndi ubwino wa kukula kwazing'ono, kulemera kwake, kuyika bwino ndi kukonza, chitetezo ndi kudalirika, ndi maonekedwe okongola.Amagwiritsidwa ntchito kwambiri m'matauni, nyumba zogona, mahotela, zipatala, mafakitale, migodi, malo opangira mafuta, ma eyapoti, njanji, ma terminals ndi malo ena opangira magetsi akunja.
Malo apansi ndi 1/3-1/5 okha a bokosi lopangidwa m'nyumba lomwe lili ndi mphamvu zofanana.Zosindikizidwa bwino, zotetezedwa bwino, palibe mtunda wotsekera.Kuchita bwino kwambiri, kotetezeka komanso kodalirika, kutayika kochepa, phokoso lochepa.Kugwirizana Kwabwino
Mzere wolowera wamagetsi okwera kwambiri umatenga pulagi ya chingwe, yomwe imatha kukhala ndi zomangira zinc oxide kuti ikwaniritse zofunika zosiyanasiyana zopatsa mphamvu zochepa.Malinga ndi zofunikira za ogwiritsa ntchito, metering yotsika-voltage ndi shunting ikhoza kuwonjezeredwa.
Mphamvu Zochulukira Zamphamvu
S11 thiransifoma, imagawidwa m'magawo atatu: chipinda chachikulu choponderezedwa, chipinda chocheperako komanso chosinthira.Imakonzedwa mwanjira "yabwino", ndipo mbali yothamanga kwambiri imatenga mtundu wa V kapena mtundu wa T wosinthira komanso ma fuse amagawo awiri.Chitetezo chingagwiritsidwe ntchito pa netiweki ya mphete komanso pa terminal, ndipo mawonekedwe amagetsi ndi osinthika komanso odalirika.

Mawonekedwe:

1. Otetezeka & Odalirika
Shell nthawi zambiri imatenga mbale yachitsulo ya aluminium zinki, chimango chokhala ndi chidebe chokhazikika komanso njira yopangira yomwe imakhala ndi ntchito yabwino yotsutsa dzimbiri kwa zaka 20 zotsimikizika.Chipinda chosindikizira chamkati chimapangidwa ndi mbale ya aluminiyamu ya alloy buckle, ndipo sangwejiyo imapangidwa ndi zinthu zosagwira moto komanso zotsekereza kutentha.Makina oziziritsira mpweya ndi dehumidification amaikidwa m'bokosi.Kugwiritsiridwa ntchito kwa zida sikukhudzidwa ndi chilengedwe cha nyengo ndi kuipitsidwa kwakunja, ndipo ntchito yabwino ikhoza kutsimikiziridwa pansi pa malo ovuta -40 ℃ ~ +40 ℃.Zida zazikulu zomwe zili m'bokosilo zatsekedwa kwathunthu, chinthucho chilibe gawo lowonekera, lomwe lingathe kukwaniritsa ngozi yamagetsi ya zero, siteshoni yonse imatha kuzindikira ntchito yopanda mafuta, chitetezo chapamwamba, kugwiritsa ntchito kwachiwiri kwa microcomputer Integrated automation system, yomwe akhoza kuzindikira popanda kusamala.

2. Mkulu digiri ya zochita zokha
Total siteshoni wanzeru kamangidwe, chitetezo dongosolo utenga microcomputer Integrated substation zipangizo zokha, kukhazikitsa, amene angathe kuzindikira telemetry, kulankhulana kutali, kulamulira kutali, kulamulira kutali.Chigawo chilichonse chili ndi ntchito yodziyimira payokha.Ntchito yoteteza relay yatha, yomwe imatha kukhazikitsa magawo ogwiritsira ntchito patali, kuwongolera chinyezi ndi kutentha m'bokosi la bokosi ndikuchenjeza utsi patali, kuti ukwaniritse zofunikira za palibe amene ali pantchito. kuyang'anira zithunzi zakutali malinga ndi kufunikira.

3. Fakitale prefabrication
Popanga, malinga ngati mlengi molingana ndi zofunikira zenizeni za substation, amapereka chithunzi chachikulu cha mawaya ndi mapangidwe a zipangizo kunja kwa bokosi, opanga amatha kuyika ndi kukonza zida zonse, kuzindikira fakitale yomanga ya substation, kufupikitsa kamangidwe ndi kupanga.Kuyika pa malo kumangofunika kuyika bokosi, kulumikiza chingwe pakati pa mabokosi, kulumikiza chingwe chotuluka, kuwongolera chitetezo, kuyesa kutumiza ndi ntchito zina zotumizira.Malo onse kuyambira pakuyika mpaka kuyitanitsa amangofunika masiku 5-8, kufupikitsa nthawi yomanga.

4. flexible kuphatikiza mode
Bokosi mtundu gawo lapansi dongosolo ndi yaying'ono, bokosi lililonse amapanga dongosolo palokha, zomwe zimapangitsa kuphatikiza kusinthasintha, pa dzanja limodzi, ife tikhoza kugwiritsa ntchito bokosi, kotero kuti 35kV ndi 10kV zida zonse anaika mu bokosi, zikuchokera lonse. kagawo kakang'ono kabokosi;Zida za 35kV zitha kuyikidwanso panja, ndipo zida za 10kV ndi control and chitetezo system zitha kuyikidwa mkati mwa bokosi.Njira yophatikizira iyi ndiyoyenera makamaka kusinthika kwa masiteshoni akale amagetsi akumidzi.Mwachidule, palibe njira yophatikizira yosakanikirana ya compact substation, ndipo wogwiritsa ntchito amatha kuphatikiza mitundu ina momasuka molingana ndi momwe zilili kuti akwaniritse zosowa zachitetezo.

5. Kusunga ndalama
Malo ang'onoang'ono amtundu wa bokosi amachepetsa ndalama ndi 40% ~ 50% poyerekeza ndi malo okhazikika a sikelo yomweyo.Zomangamanga (kuphatikiza ndalama zogulira malo) zagawo laling'ono lamtundu wa bokosi ndi zochepera yuan 1 miliyoni poyerekeza ndi zomwe zili pamalopo wamba potengera sikelo ya 4000kVA ya 35kV single main substation. -mtundu wa substation ungathe kukonza zinthu, kuchepetsa ntchito yokonza, ndikupulumutsa pafupifupi 100,000 yuan ya ntchito ndi kukonza ndalama chaka chilichonse, ndipo phindu lonse lachuma ndi lalikulu kwambiri.

6. Malo okhala ndi anthu ochepa
Potengera chitsanzo cha 4000kVA chagawo chachikulu chimodzi monga mwachitsanzo, kumanga kagawo kakang'ono ka 35kV kudzakhala malo okwana 3000㎡ ndipo kumafuna uinjiniya waukulu. kokha kwa sikelo yofanana ya substation chimakwirira kudera la 1/10, akhoza kuikidwa pakati pa msewu, lalikulu ndi ngodya fakitale, mogwirizana ndi dziko kupulumutsa ndondomeko.

7. Kukongola mawonekedwe
Bokosi mawonekedwe kapangidwe ndi wokongola, pa mfundo kuonetsetsa kudalirika kwa magetsi, mwa kusankha bokosi gawo lapansi chipolopolo mtundu, kotero zosavuta kugwirizanitsa ndi chilengedwe ozungulira, makamaka oyenera kumanga m'tawuni, angagwiritsidwe ntchito ngati substation atakhazikika, itha kugwiritsidwanso ntchito ngati malo ogwiritsira ntchito mafoni, ndi gawo la zokongoletsera ndi kukongoletsa chilengedwe.
