isithuthi Sokuphakamisa Esingasolwa Ngokwesibhamu Sase-Distribusheni Esinamandla Amashumi Amakhulu Amashibili Namasibhozo (630–5000 kVA), 20kV

U DINGXIN 20kV European Box Substation yilungisele isibayi esisemthwakathini sokubhala isibayi esinamandla, esithumela umsebenzi wokugcina amandla okwesibayi esikhulu esingaphansi kwezindawo zokusebenza kwamandla, ngokuphelele, emva kwezinkulungwane zokufaka emsebenzini. Amaswitchgear ayo amandla amakhulu, isitansifomu sokusambisa amandla, nezinkulungwane zokugcina amandla angaphansi zihlanganisiwe kahle emseleni wokubhala isibayi, futhi ziyenza isibayi esiphila, esihle, nesibalulekile sokusambisa amandla. Amandla amakhulu ayafika ngamaswitchgear ayo amandla amakhulu, ayabizwa phansi ngositansifomu, bese bayasambiswa ngamaswitchgear ayo amandla angaphansi — konke kusodwa kusibayi esisodwa, esinamandla angaphandle.

Kukhona ukulinganisa nesitansifomu esincane sase-Amerika esisodwa emhlabeni, isibayi sase-Europe sibhekisela kakhulu ekubhalweni kwezinkulungwane zokusebenza kahle, kuyaduma izinkulungwane zokugcina amandla ezimandla ezinkulu / izinkulungwane zokugcina amandla ezimandla ezinkulu, izinkulungwane zokusambisa amandla angaphansi, nesitansifomu kuhle — okuyenza isibayi sibe khulu kodwa sibeka isibayi esiphela, esisodwa.

Izistatimende ze-European box ze-DINGXIN zihlanganiswa ngamatransformer, amashidi we-high-voltage ne-amashidi we-low-voltage, azohlukaniswa ngokugqamile ngamacable noma ezinye izindlela zokuthumela. Izixhobo zihlelwe ngendlela "mu" shape noma "pin" shape ngaphakathi kwekiosk ye-steel-structure, kuvumela ukulungiselelwa okuvinjelwe ngokwahlukana ngezindawo zokusebenza nezidingo zokusebenza.

Ukufaka kwezixhobo zonke ngaphakathi nokubekiwe kubekwe kisikhangeli ngaphambi kokuthunyelwa. Isenzo sezindawo zihlalo kufakelwe kuthi kubukele ukulungiselela kwekiosk kusisebenzi esakhiwe ngaphambi kwaye ukuxhunyanisa amacable e-input ne-output — akudingeki igumbi elwahlukileyo le-distribution. Isikrwele se-kiosk siphinde siphakamise isilinganiso esinobulungiswa, ukufakwa okubhokodelelo kanye nokusebenza kumhlabathi wonke, kuvumela ukuba kube yisimo esifanelekileyo kubazalwane bezokugcina nezokusebenza okwahlukileyo noma okubuyiselwe.

Lokhuluma kwezinhlangano zezibalo zaseChina: GB 1094.1-2013, GB/T 11022-2011, GB 7251.1-2013 ne-JG/T 10217-2013, futhi izimo zokusebenza zakho zihambisana nezimo zokusebenza okudingekayo kwezithuthi zokugcina nezinkampani zokuhlela kuzo.

• Kwakhiwe ngaphandle kwendawo, ukufaka kwezinto ngokujwayelekile Ukufaka kwezinto zonke zokugcina kwenziwe ngaphandle kwendawo kabefore ukuthunywa. Umsebenzi wendawo uyisifunda kuphela sokubeka isubstation emsebenzini wakho wokuphatha nokuxhuma amacable we-inlet/outlet — okukhula kakhulu ukuthunywa kwezinto.

• Inhambili Enkulu neYimali Ezingenakuthathwa Isithuthi sesibhokisi sikhona kakhulu ukuthi siyakwazi ukuthunywa. Kuyisifundo esihle kakhulu kwezindlela zokusebenza zokugcina ezizimangaliso, isubstation iyakwakhiwa kabusha endaweni enye ukusebenza kabusha ngaphandle kokungafanele kwezinto.

• izindleko Ezilula Ngaphansi Kwe-50% Kwezindlu Zomphakathi Isibhokisi se-Europe sithintisa ngokuvamile i-50% kwezindlela zokuthenga kunezindawo zokugcina zokuthatha izinsiza, sithintisa isikhathi sokubakha ngokuvamile ngesibili, futhi akudingi abantu bendawo ekusebenzeni — okuthintisa izindlela zokuthenga kwezinto nezindlela zokusebenza kwezinto ngokuvamile.

• Ukubulala Okuncane Kwezindawo Akudingeki igumbi lokwahlukanisa elwahlukile — kufanele kube yisisekelo esisodwa kuphela. Lokhu kubuyisela kakhulu ukubulala kwezimali, indawo efakwe kuyo, nokubonakala kwezibulalo.

• 5. Ukulungiswa Okuvamile "Mu" noma "Pin" Amagumba e-HV, ithransifomha, nezindawo ze-LV zingalungiswa ngendlela "mu" noma "pin", zifakazela ezinye-izimo zezindawo nezidingo zokuhamba kwamacabeli.

• 6. Ukuvikela Okumelene Nokubulala Kaphesheya Igumbi le-oil libhalwe IP68 kanye nezindawo eziphakeme kanye ezincane zibhalwe IP54, ukuqinisekisa ukusebenza okubalulekile emasimini anqunyelwe kanye emanzini nangaphandle, ngokungafani ngezulu ezintambo ezinokuba nge-60 dB.

Umbuzo 1: Isikhundla sesibhakabhaka se-Europe yini? Isikhundla sesibhakabhaka se-Europe yindlela yokwenza isikhundla sesibhakabhaka esisemthwakathini esinamaphuzu amabili, isikhundla sesibhakabhaka, isikhundla sesibhakabhaka sokugcina kanye nesikhundla sesibhakabhaka sokusula emakhonjeni okukhulu. Kuyasebenza ngendlela efanayo no-sikhundla sesibhakabhaka sokusebenza kahle kodwa kwenziwa emzini wokwenza izinto, kusuka kumkhakha kanye kusobala ukuthi kusetyenziswa ngaphandle kokukhanya.

Umbuzo 2: I-voltage ne-ampacity yesikhundla sesibhakabhaka se-DINGXIN se-20kV ziyiphi? I-voltage ephezulu: 10/20/35 kV, i-voltage emphezulwini: 0.315–0.5 kV, i-ampacity ekhethiwe: 630–5000 kVA (isikhundla sesibhakabhaka sokugcina se-50–2000 kVA sifana nalo).

Umbuzo 3: I-degree yokuhlinzekisa yomkhakha uyiphini? I-tank yesithelo siyisilungile ku-IP68 futhi izikhundla zesibhakabhaka se-HV/LV zisilungile ku-IP54, sizokunika ukulinda kahle ngaphandle kokukhanya kanye nokufika kwamafuta nezilwane.

Umbuzo 4: Kuyahlukana kanjani nesikhundla sesibhakabhaka sokusebenza kahle? Kusetha malini ngokuphelele kwe-50%, kusindisa isikhathi sesakhiwo ngokuphindaphindwe kabili, kudinga kuphela isisekelo esisodwa esingafani noqatha olukhethekile, kungadingi abantu basebenzayo esikhathini sesiseko.

Ubu 5: Ingaba isubstation ingakhokhelwa? Yebo. Isakhiwo seshell ye-kiosk sinesandla esinamandla — sifanele kumaseko amancane, ingakhululwa futhi ingafakwa esinye isikhungo ukuzisebenzisa futhi.

Ubu 6: Kukhona ukhetho lwezinhlelo zini ezitholakala? Isubstation isethula izinhlelo ezimbili: ebalulekileyo "mu" noma "pin", ekuvumela ukulungiswa okuvamile kwe-HV switchgear, ithransfomha ne-LV compartments.

Ubu 7: Iziphawu ezimangalisayo zizifani nazo izinhlelo? GB 1094.1-2013, GB/T 11022-2011, GB 7251.1-2013 ne-JG/T 10217-2013.

Ubu 8: Kukhona ukuphathwa kwe-vector groups ne-tap ranges? I-vector groups: Dyn11, Dyn11yn11 ne-Yd11d11; ukulungiswa kwe-tap kungavuniwe: ±2×2.5%; isilinganiso se-tap se-tranformer: ±2×2.5% noma ±5%.
