I-CNHWX-12 ESEMTHETHWENI ESIQHELEKILEYO ESIVALIWEYO IKHEJI
Ukusebenza kwezinto ezibonakalayo eziphambili kunye nesekondari ye-fusion ye-standard standardized ring cage box ayikho ngaphantsi kwe-S304 insimbi engenasici okanye i-GRC (i-glass fiber reinforced cement) kunye nezinye izinto. Igobolondo kufuneka ibe namandla aneleyo omatshini kwaye akufanele ikhubazeke okanye yonakaliswe ngexesha lokunyuswa, ukuthutha kunye nokufakwa. Umgangatho wokukhusela webhokisi yangaphandle akufanele ube ngaphantsi kwe-IP43. Ukuba izinto zekheji yesangqa sisinyithi, ubukhulu begama ≥ 2mm, kwaye ukutenxa okuvumelekileyo komgangatho kuyahlangabezana neemfuno zokuchaneka kweKlasi B ye "GB/T 708 Dimensions, Shapes, Weights and Allowable Deviations of Cold-rolled Steel Plate and Steel. Imihlubu".
Ibhokisi yangaphandle yesinyithi kufuneka iphathwe ngeteknoloji yokugquma i-anti-corrosion. Ingubo kufuneka ifane kwaye ihambelane nobukhulu. Ingubo kufuneka ibe nokubambelela okuqinileyo.
Isishwankathelo
Ngophuhliso oluqhubekayo kunye nenkqubela phambili yoluntu, igridi yamandla edolophini yelizwe lam ifumene utshintsho olukhulu. Uninzi lwezixeko ziye zaqulunqa okanye zenza iindawo ezininzi ezithatha umbane ngamandla. Ngaphambili, unikezelo lwamandla ombane olusuka kwi-12/24kV kwimigca yesitishi esingaphantsi kwe-12/24kV [okanye iintambo zesebe] ukuya ngqo kubasebenzisi abakwazanga ukuhlangabezana neemfuno zophuhliso lwedolophu. Ngenxa yoko, indlela entsha yonikezelo lwamandla iye yavela ukunika amandla kubasebenzisi ngokutshintsha. Nangona kunjalo, ngenxa yokuqina koxinaniso lwedolophu, ezinye izixhobo zokutshintsha zasekhaya ziye zathintelwa ngumhlaba kunye nocwangciso lwedolophu. Ke ngoko, kuye kwavela ibhokisi yeringi ye-high-voltage ephezulu kunye nesebenzayo yangaphandle (esemgangathweni). Le mveliso ayifuni ukwakhiwa koluntu kwaye ihlala kwindawo encinci. Uqwalaselo lubhetyebhetye kakhulu kwaye indlela yonikezelo lwamandla inokuthenjwa ngakumbi. Ulwakhiwo, ukufakwa kunye nexesha lokucoca lincitshiswe kakhulu, kwaye ixabiso lilonke liyancitshiswa.
Ngophuhliso loshishino lwanamhlanje, inqanaba lokuzisebenzela kunye nobukrelekrele bezixhobo zolawulo lombane liya linyuka ngokunyuka. Itekhnoloji yale mihla yombane, iteknoloji yesivamvo, itekhnoloji yonxibelelwano, kunye neteknoloji yenethiwekhi yekhompyutha isetyenziselwa ukubeka esweni, ukukhusela, kunye nokubeka esweni izixhobo zombane phantsi kweemeko eziqhelekileyo kunye neengozi. Ukudityaniswa kolawulo kunye nokulinganisa ukufikelela kulawulo olulungileyo kuye kwaba yinto engenakuphepheka kunye nesikhokelo sophuhliso.
Ibhokisi lendandatho yangaphandle ye-voltage ephezulu (esemgangathweni) ithatha kwaye ifunde kwi-teknoloji yangaphandle yangaphandle, idibanisa i-12 / 24kV switch cabinet, i-circuit breaker, i-switch switch, i-transformer yangoku kunye ne-voltage, i-12 / 24kv yombane we-PT, isikhululo sokutshintsha i-FTU, i-RTU, unxibelelwano ulawulo lweTheminali (CCu). Imitha ye-12/24kV kunye nokufundwa kweemitha ezizenzekelayo, ukunikezelwa kwamandla e-USP kunye nezixhobo ezibonisayo zifakwe kwaye zihlanjululwe kwibhokisi yensimbi engenasici ekhutshwayo, etywiniweyo kunye neyomswakama, ngaloo ndlela iqonda iinkqubo eziphambili kunye nesekondari kuthungelwano lokusasazwa kwedolophu. Udibaniso kunye nendibano yeemodyuli mfutshane umjikelo wokwakha kunye nokuphucula kakhulu ukuthembeka kokusebenza kwegridi yamandla asezidolophini.
