Kune akawanda mashandisirwo epasi, 40% IACS copper clad steel (CCS) conductor ndiyo sarudzo chaiyo, uye solid copper ndiyo sarudzo chaiyo chete kana fault-current capacity kana soil chemistry ichida izvozvo. Ndinoti mushure memakore gumi nemaviri ekutumira zvinhu zvese kubva kuXinchang factory yedu: waya ye40% IACS CCS inopa inenge 40% ye conductivity ye annealed copper pa2 kusvika kana simba rekudhonza, copper layer ye 0.25 mm iyo kugadzirwa kwedu kunotsigira hupenyu hwebasa hunopfuura makore makumi mashanu, uye scrap value yakaderera zvekuti mbavha dzinonyanya kuifuratira. Solid 99.97% copper ichiri kukunda pa raw conductivity — 90% kusvika 99.9% IACS zvichienzaniswa neCCS yedu ye 15% kusvika 40% IACS — saka kana kuverenga kwako kwe IEEE 80 fault-current kusina kusiya margin, copper ndiyo mhinduro yechokwadi. Chikamu chasara chechinyorwa chino chinotsanangura zvinhu zvishanu zvandinotarisa nemaneja wese wekutenga zvinhu anondibvunza mubvunzo weCCS-kana-copper, nenhamba chaidzo kubva mumishumo yedu yemiedzo yemuchina pane zvichemo zvebhurocha.

Chiratidzo che40% cheIACS: Sei Chichiramba Chichionekwa Mumagadzirirwo Ekushandisa?

IACS inomirira International Annealed Copper Standard, iyo yakaitwa muna 1913 iyo yakaisa conductivity yemhangura yakanyungudutswa mukutengeserana se100% uye yakapa resistivity ye0.017241 Ω·mm²/m pa20°C. Nhamba yega yega conductivity muchinyorwa chino - uye nhamba yega yega iri pazvitupa zvedu zvemuchina - iperesenti yechiyero ichocho. Kana specification ichida "40% IACS wire," iri kukumbira conductor ine resistivity iri 0.017241 yakakamurwa ne0.40, iyo inosvika 0.0431 Ω·mm²/m. Ndinoona kuti kana vatengi vaona division imwe iyoyo, gakava rese reCCS-versus-copper rinova mathretics pachinzvimbo chekushambadzira.

Sei 40% kwete 30% kana 21%? Muruzivo rwedu rwekutumira kunze kwenyika, giredhi re40% rakava chinhu chinoshandiswa nevatengi nekuda kwechikonzero chinoshanda: ndiyo kirasi yepamusoro-soro yekufambisa zvinhu iyo simbi yakaputirwa nemhangura inosvika mumagiredhi akajairwa anodhonzwa akafukidzwa neASTM B227(Giredhi 40 HS neGiredhi 40 EHS) uye zvivakwa zvakakanganisika zveASTM B228. Wedzera pamusoro pe40% uye unenge uchikumbira kuti pave nejira rakakora remhangura kupfuura iro rakagadzirwa neboka rezvigadzirwa zvakaoma, uye musiyano wemutengo unobva wadzikira nekukurumidza kana uchienzaniswa nemhangura yakasimba.Nekuti ukobvu hwecladding hunosimudzira mutengo wechinhu chacho, kondakita yeCCS inopfuura 40% IACS inorega kuva imwe nzira inodhura kupfuura mhangura yakasimba.Ndinoudza zvikwata zvinotenga zvinhu kuti zvibate 40% IACS senzvimbo yepamusoro yeCCS, uye kuti zvibate chero chinhu chiri pamusoro payo sechiratidzo chekungotenga mhangura yakasimba.

Waya yesimbi yakaputirwa nemhangura padura redu rekugadzira reXinchang, yakazadzwa neroli yezvirongwa zvepasi — makirasi ekufambisa magetsi kubva pa15% kusvika 40% IACS pamutsetse mumwe chete.

Kufambisa Kwesimbi Yakaputirwa Nemhangura Mumagridi Echokwadi Ekugadzika: Unorega Zvakadini Chaizvo?

Papepa, musiyano wekufambisa magetsi unotaridzika kunge wakanyanya kuipa: waya yedu yemhangura yakachena inoyedzwa pa90%–99.9% IACS ine resistivity iri pasi pe0.017241 Ω·mm²/m, nepo CCS yedu iri pakati pe15%–40% IACS. Mugridi yegrounding, zvisinei, nhamba inokosha haisi conductivity iri yoga - ndeyekuti conductor inopona here kana zvikanganiso zvawakapihwa nekudzidza kwako. IEEE 80, ndiyo nzira inoshandiswa zvakanyanya pakugadzira grid re substation (IEEE Std 80), vatungamiriri vemagetsi vanoisa saizi nekubatanidza magetsi nekufamba kwenguva, kwete nekudzivirira chete. Patinoshandisa 40 kA, 0.5-second fault kuburikidza ne standard fusing formulas, 40% IACS CCS conductor inoda kanenge ka2.5 kupfuura copper kuti isvike pamuganhu wekupisa wakafanana - ndiyo chaiyo conversion factor, uye ndinoinyora mu quotation yega yega yatinoburitsa.

Iyo 2.5× factor inonzwika sekunge ichakanganisa mutengo wechinhu chose. CCS padhayamita yakakura ichiri kushandisa mhangura shoma zvakanyanya nehuremu,Nekuti musimboti wesimbi unotakura mutoro wemakanika, jira remhangura re 0.25 mm chete ndiro rinodiwa kuti riite basa rekufambisa simbi.— uye pa60 Hz fault frequency magetsi anoungana pamusoro chero zvakadaro, ndipo chaipo pane mhangura. Chikwata chedu chemainjiniya chakafambisa vatengi vakati wandei kuburikidza nepfungwa iyi yeganda-effect nemifananidzo chaiyo yezvikamu zvakasiyana; kana vangoona kuti nzira yemagetsi nemhangura zviri mudenderedzwa rekunze rimwe chete, kuramba kwekufambisa magetsi kunowanzo nyorova.

Pandisingakurudzire CCS pane zvakasiyana zvakanyanya: nzvimbo dzemumaguta dzakamanikana uko upamhi hwemugero uye kudzika kwetsvimbo zvinogadziriswa uye ongororo yezvikanganiso haipe nzvimbo yekuwedzera saizi yemutyairi. Mumapurojekiti iwayo tinotaura waya yedu yemhangura yakachena ye99.97% pasina kukumbira ruregerero,nekutihapana mukana wekushandisa michina unotsiva chikamu chausingakwanise kuisa. Mutengesi anosundidzira CCS mumamiriro ezvinhu akadaro ari kutengesa achipesana neongororo yako yezvikanganiso, uye ndingada kurasikirwa neodha pane kuita kuti grid isashande zvakanaka mugore rechitatu.

CCS yakasungirirwa pasi pekukwidziridzwa: monofilament yega yega (1.4–3.2 mm) isimbi yakabatana nesimbi kune 0.25 mm copper layer - chivakwa chiri shure kwe40% IACS rating.

CCS kana Solid Copper: Zviyero Zvishanu Zvinosarudza Kuti Ndeupi Muiti Wemuchina Anofanira Kukunda Zvaunoda

Kana mutengi wemagetsi akanditumira RFQ inoti “CCS kana copper — ndapota ndipei zano,” handipindure nedatasheet. Ndinopindura nekuenzanisa kwemitsara mishanu pazasi,nekutiMumakore gumi nemaviri ekutenga zvinhu kunze kwenyika, sarudzo iyi yagara ichienderana nechimwe chezvinhu zvishanu izvi: conductivity, simba remakanika, nguva yekuora, kubatwa nekubiwa, uye kufukidza zviyero.

Kuongorora Kwechokwadi Kwemakanika: Ko Mhangura Yakasimba Inogona Kupona Here Kana Yadhonzwa?

Heino nzira yekukundikana isingamboonekwi mumachati ekufambisa magetsi. Makore mashoma apfuura mumwe mukondirakita akatibata mushure mekunge waya yemhangura yakabviswa kubva kune imwe nzvimbo yakanganiswa zvakanyanya panguva yekuisa grid-in kwenguva refu; vashandi vakangoona kukuvara kwacho apo kuverenga kwegrid resistance kwakadzoka kusingaenderane panguva yekufamba.
