Ma substations ndi njira yabwino kwambiri, nthawi iliyonse yomwe zida ndi mafakitale zikuyenera kulumikiza ma gridi kwakanthawi komanso magetsi osakhalitsa.
Mapulogalamuwa amachokera ku magetsi panthawi yadzidzidzi kapena kuzimitsidwa komwe kunakonzedwa, kupita ku zochitika, kusuntha katundu, ndi kuphatikizika kwa mbadwo wogawidwa kapena wongowonjezedwanso.
Zokwera pama skid, ma trailer kapena zotengera za njanji, misewu kapena mayendedwe apamlengalenga, malowa amabwera m'njira yokonzekera kulumikiza, misonkhano yathunthu ndipo amapangidwa kuti azitsatira malamulo a gridi komanso kuyenda kosavuta.Njira zothetsera magetsi zilipo mpaka 420 kV ndi mphamvu zonse, ndikuwonetsetsa kuti magetsi odalirika komanso apamwamba kwambiri.
Chitsimikizo chapamwamba, thanzi, chitetezo ndi miyezo ya chilengedwe
Mayankho okhathamiritsa a magwiridwe antchito apamwamba, kuchita bwino, kusinthasintha, kudalirika komanso kutsika mtengo kwa moyo
IEC 61850 yowongolera, chitetezo ndi njira zoyankhulirana zimathandizira kuwongolera ndi kuyang'anira kwanuko komanso kutali
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.Mbale yosindikizira yamkati imapangidwa ndi mbale ya aluminiyamu ya alloy buckle, ndipo sangwejiyo imapangidwa ndi zinthu zosagwira moto komanso zotsekemera zotentha.Makina oziziritsira mpweya ndi dehumidification amaikidwa m'bokosi.Kugwiritsiridwa ntchito kwa zida sikukhudzidwa ndi chilengedwe cha nyengo ndi kuipitsidwa kwakunja, ndipo ntchito yabwinoyi ikhoza kutsimikiziridwa pansi pa malo ovuta -40 ℃ ~ +40 ℃.Zida zoyambirira zomwe zili m'bokosilo zatsekedwa kwathunthu, chinthucho sichikhala ndi gawo lowonekera, lomwe lingathe kukwaniritsa ngozi yamagetsi ya zero, siteshoni yonse imatha kuzindikira ntchito yopanda mafuta, chitetezo chachikulu, 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 automation, 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 mukwaniritse zofunikira za palibe amene ali pantchito. kuyang'anira zithunzi zakutali malinga ndi kufunikira.
3. Fakitale prefabrication
Popanga, malinga ngati mlengi malinga 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 ocheperapo kuyambira pakuyika mpaka kuyitanitsa amangofunika masiku 5-8, kufupikitsa nthawi yomanga.
4. flexible kuphatikiza mode
Bokosi mtundu substation dongosolo ndi yaying'ono, bokosi lililonse amapanga dongosolo palokha, zomwe zimapangitsa kuphatikiza kusinthasintha, mbali imodzi, ife tonse 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 makina owongolera ndi chitetezo zitha kuyikidwa mkati mwa bokosi.Njira yophatikizirayi ndiyoyenera makamaka kusinthika kwa ma gridi akale 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 wamba a sikelo yomweyo.Zomangamanga (kuphatikiza ndalama zogulira malo) za malo opangira mabokosi ndi zochepera yuan miliyoni imodzi poyerekeza ndi malo wamba wamba potengera sikelo ya 4000kVA ya 35kV single main substation. -gawo laling'ono limatha kukonza zinthu, kuchepetsa ntchito yokonza, ndikusunga ndalama zokwana 100,000 yuan zogwirira ntchito ndikukonza chaka chilichonse, ndipo phindu lonse lazachuma ndilambiri.
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 yomweyo ya substation chimakwirira kudera la 1/10, akhoza kuikidwa pakati pa msewu, lalikulu ndi ngodya fakitale, mogwirizana ndi dziko kupulumutsa dziko 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 mizinda, angagwiritsidwe ntchito ngati substation atakhazikika, itha kugwiritsidwanso ntchito ngati malo ogwiritsira ntchito mafoni, ndi gawo la zokongoletsera ndi kukongoletsa chilengedwe.
