Nguva itsva yeindasitiri yemotokari itsva ine basa rekuchinja maindasitiri nekuvandudza nekudzivirira nharaunda yemhepo, izvo zvinotungamira zvikuru kukura kwemaindasitiri kwetambo dzine simba guru nezvimwe zvinhu zvine chekuita nemotokari dzemagetsi, uye vagadziri vetambo nemasangano ekupa zvitupa vakaisa simba rakawanda mukutsvagisa nekugadzira tambo dzine simba guru dzemotokari dzemagetsi. Tambo dzine simba guru dzemotokari dzemagetsi dzine zvinodiwa pakushanda kwepamusoro-soro muzvinhu zvese, uye dzinofanira kusangana neRoHSb standard, zvinodiwa zvemhando yeUL94V-0 zvinodzora moto uye kushanda kwakadzikama. Pepa iri rinopa zvinhu uye tekinoroji yekugadzirira tambo dzine simba guru dzemotokari dzemagetsi.
1. Zvinhu zvetambo yemagetsi yakakwira
(1) Zvinhu zvinofambisa tambo
Parizvino, kune zvinhu zviviri zvikuru zve cable conductor layer: copper nearuminiyamu. Makambani mashoma anofunga kuti aluminium core inogona kuderedza zvakanyanya mari yekugadzira, nekuwedzera copper, iron, magnesium, silicon nezvimwe zvinhu zvichibva pazvinhu zvearuminiyamu yakachena, kuburikidza nemaitiro akakosha akadai se synthesis ne annealing treatment, kuvandudza electrical conductivity, bend performance uye corrosion resistance ye cable, kuitira kuti isangane nezvinodiwa zvekukwanisa kurema zvakafanana, kuti iwane mhedzisiro yakafanana neye conductors copper core kana kutopfuura. Saka, mari yekugadzira inoponeswa zvikuru. Zvisinei, mabhizinesi mazhinji achiri kuona copper sechinhu chikuru che conductor layer, kutanga, resistivity ye copper yakaderera, uye ipapo mashandiro mazhinji e copper ari nani pane earuminiyamu padanho rimwe chete, senge large current capacity, low voltage loss, low energy consumption uye strong viability. Parizvino, kusarudzwa kwe conductors kunowanzo shandiswa national standard 6 soft conductors (single copper wire elongation inofanira kunge yakakura kupfuura 25%, dhayamita ye monofilament iri pasi pe 0.30) kuti ive nechokwadi chekupfava uye kusimba kwe copper monofilament. Tafura 1 inoratidza zvinodiwa kuti zvinhu zvinoshandiswa nemhangura zvinofambiswa nemhangura zvisashande.
(2) Zvinhu zvinodzivirira tambo
Nzvimbo yemukati memotokari dzemagetsi yakaoma, pakusarudza zvinhu zvinodzivirira kupisa, kune rumwe rutivi, kuve nechokwadi chekuti insulation layer inoshandiswa zvakachengeteka, kune rumwe rutivi, zvakanyanya sezvinobvira kusarudza kugadzirisa kuri nyore uye zvinhu zvinoshandiswa zvakanyanya. Parizvino, zvinhu zvinodzivirira kupisa zvinoshandiswa zvakanyanya ipolyvinyl chloride (PVC),polyethylene yakabatana (XLPE), silicone rabha, thermoplastic elastomer (TPE), nezvimwewo, uye hunhu hwazvo hukuru zvinoratidzwa muTafura 2.
Pakati pazvo, PVC ine mutobvu, asi RoHS Directive inorambidza kushandiswa kwemutobvu, mercury, cadmium, hexvalent chromium, polybrominated diphenyl ethers (PBDE) uye polybrominated biphenyls (PBB) nezvimwe zvinhu zvinokuvadza, saka mumakore achangopfuura PVC yakatsiviwa neXLPE, silicone rabha, TPE nezvimwe zvinhu zvine hushamwari kune zvakatipoteredza.
(3) Zvinhu zvekudzivirira tambo
Chidziviriro chakakamurwa kuita zvikamu zviviri: chidziviriro chehafu-conductive uye chidziviriro chakarukwa. Kudzivirira kwehuwandu hwezvinhu zvekudzivirira zvehafu-conductive pa20 ° C uye 90 ° C uye mushure mekukwegura inyanzvi yakakosha yekuyera zvinhu zvekudzivirira, izvo zvinosarudza zvisina kunanga hupenyu hwebasa retambo ine voltage yakawanda. Zvinhu zvekudzivirira zvehafu-conductive zvinosanganisira ethylene-propylene rubber (EPR), polyvinyl chloride (PVC), uyepolyethylene (PE)zvinhu zvakagadzirwa. Kana zvinhu zvisina kunaka uye mwero wemhando usingagone kuvandudzwa munguva pfupi, masangano ekutsvagisa kwesainzi nevagadziri vezvinhu zvetambo vanotarisa pakutsvaga tekinoroji yekugadzirisa uye chiyero chefomula yezvinhu zvekudzivirira, uye vanotsvaga hunyanzvi muhuwandu hwezvinhu zvekudzivirira kuti vawedzere kushanda kwese kwetambo.
2. Maitiro ekugadzirira tambo yemagetsi epamusoro
(1) Tekinoroji yetambo yemuchina
Maitiro ekutanga etambo akagadzirwa kwenguva yakareba, saka kunewo maitiro avo chaiwo muindasitiri nemabhizinesi. Mukuita kwedhirowa rewaya, zvichienderana nemaitiro edhirowa rewaya imwe chete, michina yekusunga tambo inogona kukamurwa kuita muchina wekusunga tambo, muchina wekusunga tambo uye muchina wekusunga tambo. Nekuda kwekupisa kwakanyanya kwemubati wemhangura, tembiricha yenguva nenguva yakareba, zvakakodzera kushandisa michina yekusunga tambo kuita tambo yekusunga tambo inoenderera mberi uye tambo yekusunga tambo kuti ivandudze kurebesa uye kupwanyika kwehuwandu hwekudhirowa kwewaya. Parizvino, tambo yepolyethylene ine cross-linked (XLPE) yakatsiva zvachose tambo yepepa remafuta pakati pe1 ne500kV voltage levels. Kune maitiro maviri akajairika ekugadzira tambo yeXLPE conductors: denderedzwa compaction uye tambo yekusunga tambo. Kune rumwe rutivi, tambo yepakati inogona kudzivirira kupisa kwakanyanya uye kumanikidzwa kwakanyanya mupombi yakabatana kuti idzvanye zvinhu zvayo zvekudzivirira uye zvinhu zvekudzivirira mugomba rewaya rakasungwa uye kukonzera marara; Kune rumwe rutivi, inogonawo kudzivirira kupinda kwemvura munzira yemuchina wekufambisa mvura kuitira kuti tambo ishande zvakachengeteka. Muchina wekufambisa wemhangura pachawo imhando yemuchina wekubatanidza tambo, iyo inonyanya kugadzirwa nemuchina wekubatanidza tambo wefuremu, muchina wekubatanidza tambo yeforogo, nezvimwewo. Kana ichienzaniswa nemaitiro ekubatanidza tambo yedenderedzwa, inogona kuve nechokwadi chekuti muchina wekufambisa tambo wedenderedzwa unogadzirwa.
(2) Maitiro ekugadzira XLPE wire insulation
Pakugadzira tambo yeXLPE ine voltage yakawanda, catenary dry cross-linking (CCV) uye vertical dry cross-linking (VCV) inzira mbiri dzekugadzira.
(3) Maitiro ekubvisa
Kare, vagadziri vetambo vakashandisa nzira yechipiri yekuwedzera tambo kuti vagadzire tambo yekudzivirira tambo, danho rekutanga panguva imwe chete vachidzivirira tambo yekudzivirira tambo uye tambo yekudzivirira tambo, uye vozobatanidza tambo yacho voibatanidza netireyi yetambo, vozoiisa kwenguva yakati rebei vozoidzivirira. Mumakore ekuma1970, nzira yekuwedzera tambo ye1+2 yakaonekwa musimbi yesimbi yakaputirwa, zvichiita kuti tambo yemukati neyekunze ipedzwe nenzira imwe chete. Nzira iyi inotanga yaburitsa tambo yesimbi, mushure menguva pfupi (2~5m), uye yozoburitsa tambo yekudzivirira tambo uye tambo yekudzivirira tambo patambo yesimbi panguva imwe chete. Zvisinei, nzira mbiri dzekutanga dzine matambudziko makuru, saka mukupera kwema1990, vatengesi vemidziyo yekugadzira tambo vakaunza nzira yekugadzira tambo yekubatanidza tambo yesimbi ... Makore mashoma apfuura, nyika dzekunze dzakatangawo dhizaini itsva ye extruder barrel head uye curved mesh plate design, nekuenzanisa screw head cavity flow pressure kuderedza kuunganidzwa kwezvinhu, kuwedzera nguva yekugadzira inoenderera mberi, kutsiva shanduko isingamiri ye specifications yehead design kunogonawo kuchengetedza mari ye downtime uye kuvandudza mashandiro.
3. Mhedziso
Mota itsva dzemagetsi dzine mikana yakanaka yekugadzirwa uye musika wakakura, dzinoda mhando dzakasiyana dzezvigadzirwa zvetambo dzemagetsi dzine mutoro wakakwira, dzinodzivirira kupisa kwakanyanya, dzinodzivirira magetsi, dzinodzivirira kukotama, dzinochinjika, dzinoshanda kwenguva refu uye dzimwe nzira dzakanaka dzekugadzira uye dzinogara mumusika. Zvishandiso zvetambo dzemagetsi dzine voltage yakawanda uye maitiro ekugadzirira kwadzo ane mikana yakakura yekuvandudzwa. Mota dzemagetsi hadzigone kuvandudza mashandiro ekugadzira uye kuona kuti dzinoshandiswa zvakanaka pasina tambo dzemagetsi.
