CB/CWB/CWW 6-35KV 200-3150A Umgca wesikhululo samandla sangaphandle esinevoltage ephezulu yohlobo lwe-ceramic eludongeni bushing
Ingcaciso yeMveliso
Icasing eludongeni ikwabizwa ngokuba yi-wall casing, i-casing waterproof, umbhobho ofakwe eludongeni, kunye ne-casing engangeni manzi yahlulwe yaba yicasing eqinile engangenwa manzi kunye ne-flexible casing waterproof.Udonga lwe-AC olusetyenziselwa ukuqhuba umbane lubizwa ngokuba yi-AC eludongeni bushing, enokwahlulwa ibe yi-capacitive eyomileyo yodonga lwe-AC kunye ne-porcelain insulated AC wall bushing, ekubhekiselwa kuyo njenge-silicone irabha bushing kunye ne-porcelain bushing ngokulandelanayo.
I-Wall-through porcelain bushings ifanelekile kwizikhululo zamandla, izitishi, izixhobo zokuhambisa amandla kunye nezixhobo zombane eziphezulu zombane ezinombane ojikelezayo we-AC ongaphantsi kwe-35kV.Zisetyenziswa njenge-insulation kunye nenkxaso yeendawo eziqhubayo ezidlula kwiindonga okanye ezinye izinto eziphantsi.Amatyholo alungele ubushushu be-ambient -40℃+40℃.
I-Wall-through porcelain bushings ihlulwe ngaphandle nangaphakathi ngokwendawo yokufakela.Ngokwesakhiwo, ihlulwe ibe luhlobo lwentonga yesikhokelo kunye nohlobo lwebhasi.Ngokutsho kwesixhobo somqhubi esisetyenzisiweyo, ihlukaniswe ibe ngumqhubi we-aluminium kunye nomqhubi wobhedu.Ngokwendawo yofakelo, yahlulwe ngohlobo oluqhelekileyo kunye nohlobo oluchasene nongcoliseko.
Ukukhethwa kwamahlahla eludongeni
1. Uhlobo kwaye uchwetheze ukhetho
Ngokwendawo yokufakela, uhlobo lwangaphakathi kunye nohlobo lwangaphandle lunokukhethwa.Ngokutsho kwesicelo, i-bushings eludongeni kunye nabaqhubi kunye
ibha yebhasi .Izixhobo zokusasaza amandla angaphakathi ngokuqhelekileyo zisebenzisa i-aluminium conductor wall bushings.
2. I-voltage elinganisiweyo ikhethiwe
ngokwemeko yokuba i-voltage elinganisiweyo ye-bushing eludongeni ayiyi kuba ngaphantsi kombane olinganisiweyo wegridi yamandla apho ikhoyo.Xa kukho umkhenkce kunye nekhephu, i-3 ~ 20kV yodonga lwangaphandle kufuneka ikhethe imveliso enamandla ombane aphezulu.Kwi-3-6kV, iimveliso ezinokunyuka kwe-voltage yemigangatho emibini nazo zingasetyenziswa.
3. Ireyithi yangoku kukukhetha
i-bushing yodonga kunye ne-conductor, kwaye i-current yayo elinganisiweyo ayiyi kuba ngaphantsi kobuninzi obuqhubekayo obusebenzayo besiphaluka.Uhlobo lwe-busbar eludongeni lwe-bushing ngokwalo alunabaqhubi, ngoko akukho ngxaki ekukhethweni kwangoku okulinganiselweyo, kodwa ubungakanani bebhasi evunyelwe ukuba idlule kwifestile kufuneka ihlolwe.

Iimpawu zemveliso kunye nendawo yokusetyenziswa
1. Nganye ineengenelo zobukhulu obuncinci, ubunzima obulula, kunye nokuhamba ngokulula.
2. I-insulator nganye edibeneyo inamandla amakhulu omatshini, isakhiwo esithembekileyo, ukusebenza okuzinzile, kunye nomda wokhuseleko ophezulu wokuqinisekisa ukusebenza ngokukhuselekileyo kwesekethe.
3. I-insulator yombane nganye edibeneyo inokusebenza okuphezulu, i-hydrophobicity elungileyo kunye nokuhamba, kunye nokumelana namabala.
4. Inesakhono esihle sokumelana nokungcoliseka kwe-flashover, kwaye inokusebenza ngokukhuselekileyo kwiindawo ezingcoliseke kakhulu ngaphandle kokucocwa ngesandla, ukuphepha umlinganiselo we-zero point.
5. Yonke i-insulator ehlanganisiweyo inokumelana ne-asidi, ukuxhathisa kwe-alkali, ukumelana nokuguga kobushushu kunye nokumelana ne-capacitance, ukusebenza kakuhle kokutywinwa, kwaye inokuqinisekisa umswakama we-insulation njalo njalo.

Ukuhlelwa kwemveliso kunye nokufakwa
Ukusetyenziswa kunye nokuhlelwa:
I-casing yenziwe ngamacandelo e-porcelain, izesekeli zetsimbi, iiflange ezikhwelayo kunye nemivalo yokuqhuba (iintonga).
I-porcelain bushings edongeni isetyenziselwa izixhobo zokuhambisa amandla kunye nezixhobo zombane eziphezulu ze-voltage kwizikhululo zamandla kunye nezikhululo ezincinci, ukuze iingcingo zigqithe kwiindawo zokubeka umhlaba, iindonga okanye iindawo ezivaliweyo zezixhobo zombane, kunye nokuxhasa iindawo zokuqhuba ukuzikhusela emhlabeni okanye kwi-insulating. indawo ebiyelweyo.
Udonga lwe-porcelain bushings lunokwahlulwa lube ludonga lwangaphakathi kunye nangaphandle-nge-porcelain bushings ngokwemeko yokusetyenziswa kwazo.Ngokwee-conductor ezahlukeneyo ezidlula embindini wayo, inokohlulwa ibe yi-busbar through-wall porcelain bushing, iconductor yobhedu ngokusebenzisa-wall porcelain bushing kunye ne-aluminium conductor through-wall porcelain bushing.
Xa umqhubi wobhedu exhunywe ngokuthe ngqo kwi-busbar, i-galvanic corrosion kulula ukwenzeka, kwaye ukunyuka kweqondo lokushisa kwendawo yokudibanisa kuphezulu kakhulu, okuya kubangela ukuba umdibaniso utshise kwaye uchaphazele ubomi bezixhobo.Ngoko ke, i-copper-aluminium transition joints kufuneka isetyenziswe, kodwa iya kuzisa ingxaki kulwakhiwo lwesiza.I-casing inokusombulula ezi ngxaki zingentla.
Udonga lwangaphakathi nangaphandle-nge-porcelain bushings luhlanganiswe kwiindawo ze-porcelain, iintonga ze-conductive, izixhobo zetsimbi kuzo zombini iziphelo kunye neeflange ezikhulayo.Udonga lwe-busbar-nge-porcelain bushing luhlanganiswe kwiindawo ze-porcelain, izixhobo zetsimbi kuzo zombini iziphelo, i-busbar splint kunye ne-flange ekhulayo (i-busbar splint idla ngokulungiswa ngumsebenzisi ngokobukhulu be-busbar).
Imiyalelo yokufakela nokusetyenziswa:
1. Udonga lwe-porcelain bushing lufanelekile kwisixhobo sokuhambisa izikhululo zamandla kunye nezikhululo apho amandla alinganisiweyo ombane we-AC angaphantsi kwe-40.5kv, ubushushu obuphakathi kwendawo yofakelo yi -40°C~+40°C, kunye ukuphakama akudluli kwi-1000m.
2. I-bushings yodonga lwangaphakathi ayifanelekanga kwiindawo apho i-enamel, izesekeli zetsimbi kunye ne-samente yokubambelela kwi-bushing yonakaliswe okanye yanele ukunciphisa ukusebenza kombane kwi-bushing.
3. Ukuba ukukhutshwa kwenxenye kwenzeka ngexesha lokusebenza kwe-porcelain bushing yodonga, khangela ukuba kukho ukuchithwa kwenxalenye ye-aluminium efafaziweyo kwi-flange okanye ngaphakathi kwendawo ye-porcelain bushing, kwaye ukuba kunjalo, thatha amanyathelo okulinganisa uxinzelelo lwexeshana ixesha.
4. Umngxuma wodonga lokufakela i-busbar ngokusebenzisa-udonga lwe-porcelain bushing kufuneka luvulwe ngokobukhulu obukhulu be-flange yayo yokuqinisa.
