Nguva itsva yeindasitiri yemotokari yemagetsi inobata huviri mishoni yekushandura maindasitiri nekusimudzira nekuchengetedza nharaunda yemhepo, iyo inofambisa zvikuru kuvandudzwa kwemaindasitiri etambo dzemagetsi akakwira uye zvimwe zvine chekuita nemotokari dzemagetsi, uye vagadziri vetambo nemasangano ezvitupa vane. yakaisa simba rakawanda mukutsvagisa nekuvandudza tambo dzemagetsi akakwira-voltage dzemotokari dzemagetsi. High voltage tambo dzemotokari dzemagetsi dzine hunyanzvi hwekuita zvinodiwa mumativi ese, uye dzinofanirwa kusangana neRoHSb standard, flame retardant giredhi UL94V-0 zvakajairwa zvinodiwa uye kushanda kwakapfava. Iri bepa rinounza zvigadzirwa uye tekinoroji yekugadzirira yetambo dzemagetsi akakwira emotokari dzemagetsi.
1.Nyaya ye high voltage cable
(1) Conductor zvinhu zvetambo
Parizvino, pane zvinhu zviviri zvakakosha zvetambo conductor layer: mhangura uye aluminium. Makambani mashoma anofunga kuti aluminium musimboti inogona kuderedza zvakanyanya mitengo yavo yekugadzira, nekuwedzera mhangura, simbi, magnesium, silicon uye zvimwe zvinhu pahwaro hwezvinhu zvakachena zvealuminium, kuburikidza nemaitiro akakosha senge synthesis uye annealing kurapwa, kuvandudza conductivity yemagetsi, kukotama. kushanda uye kusadzivirirwa kwetambo yetambo, kuitira kuti isangane nezvinodiwa zvehumwe hukuru hwekutakura, kuwana mhedzisiro yakafanana nemhangura core conductors kana kunyange zvirinani. Nokudaro, mari yekugadzira inoponeswa zvikuru. Nekudaro, mabhizinesi mazhinji achiri kuona mhangura sechinhu chikuru cheiyo conductor layer, chekutanga, iyo resistivity yemhangura yakaderera, uyezve yakawanda yekushanda kwemhangura iri nani pane iyo yealuminium padanho rimwe chete, senge yakakura ikozvino. kutakura simba, kupera kwemagetsi mashoma, kushandiswa kwesimba shoma uye kuvimbika kwakasimba. Parizvino, kusarudzwa kwemakondakita kunowanzo shandisa iyo yenyika chiyero 6 yakapfava conductors (imwe yemhangura waya elongation inofanirwa kunge yakakura kupfuura 25%, dhayamita yemonofilament iri pasi pe0.30) kuve nechokwadi kupfava uye kusimba kwemhangura monofilament. Tafura 1 inodonongodza zviyero zvinofanirwa kusangana zvezvinowanzo shandiswa copper conductor zvinhu.
(2) Insulating layer zvinhu zvetambo
Mamiriro emukati emotokari dzemagetsi akaomarara, mukusarudzwa kwezvinhu zvinodzivirira, kune rumwe rutivi, kuve nechokwadi chekushandiswa kwakachengeteka kwevhavha yekudzivirira, kune rumwe rutivi, sezvinobvira kusarudza kushandiswa nyore uye kushandiswa zvakanyanya. Parizvino, iyo inowanzoshandiswa insulating zvinhu ndeye polyvinyl chloride (PVC),cross-linked polyethylene (XLPE), silicone rabha, thermoplastic elastomer (TPE), nezvimwewo, uye midziyo yavo huru inoratidzwa muTebhu 2.
Pakati pavo, PVC ine lead, asi RoHS Directive inorambidza kushandiswa kwe lead, mercury, cadmium, hexvalent chromium, polybrominated diphenyl ethers (PBDE) uye polybrominated biphenyls (PBB) nezvimwe zvinokuvadza, saka mumakore achangopfuura PVC yakatsiviwa ne. XLPE, silicone rabha, TPE uye zvimwe zvakatipoteredza zvine hushamwari zvinhu.
(3) Cable shielding layer material
Iyo shielding layer yakakamurwa kuita zvikamu zviviri: semi-conductive shielding layer uye braided shielding layer. Iro vhoriyamu resistivity ye semi-conductive shielding zvinhu pa20 ° C uye 90 ° C uye mushure mekuchembera yakakosha tekinoroji indekisi yekuyera iyo inodzivirira zvinhu, iyo inosarudza zvisina kunanga hupenyu hwesevhisi yeyakakwira-voltage tambo. Zvakajairika semi-conductive shielding zvinhu zvinosanganisira ethylene-propylene rubber (EPR), polyvinyl chloride (PVC), uyepolyethylene (PE)based materials. Munyaya yekuti iyo mbishi haina pundutso uye nhanho yemhando haigone kuvandudzwa munguva pfupi, masangano ekutsvagisa sainzi uye vanogadzira zvinhu zvematambo vanotarisa pakutsvagisa tekinoroji yekugadzira uye fomula reshiyo yezvinhu zvinodzivirira, uye kutsvaga hunyanzvi mune kuumbwa kwechiyero chekudzivirira zvinhu kuvandudza kushanda kwese kwetambo.
2.High voltage cable kugadzirisa maitiro
(1) Conductor strand tekinoroji
Iyo yakakosha maitiro etambo yakagadziriswa kwenguva yakareba, saka kune zvakare yavo yakajairwa yakatarwa muindasitiri nemabhizinesi. Mukuita kudhirowa kwewaya, zvinoenderana nemaitiro asina kumonyoroka ewaya imwe chete, midziyo yekumisikidza inogona kupatsanurwa kuita muchina usingachinjiki, muchina wekusungirira usingachinjiki uye muchina unomonereka/usingachinjiki. Nekuda kwekukwira kwekristaro tembiricha yemhangura kondakita, tembiricha yekureba uye nguva yakareba, zvakafanira kushandisa isina kumonyoroka muchina muchina kuita kudhirowa nekuenderera mberi nekudhonza monwire kuvandudza kureba uye kutsemuka kweyero yekudhirowa waya. Parizvino, iyo cross-yakabatana polyethylene tambo (XLPE) yakatsiva zvachose tambo yepepa remafuta pakati pe1 ne500kV voltage level. Kune maviri akajairwa conductor ekugadzira maitiro eXLPE conductor: denderedzwa compaction uye waya twisting. Kune rimwe divi, waya yepakati inogona kudzivirira tembiricha yakakwira uye kudzvanywa kwepaipi-yakabatana pombi yekutsikirira zvinhu zvayo zvekudzivirira uye zvinhu zvekudzivirira mukati megeji rewaya rakasungwa uye kukonzera tsvina; Kune rumwe rutivi, inogonawo kudzivirira kupindira kwemvura pamwe negwara rekondukita kuti ive nechokwadi chekushanda kwakachengeteka kwetambo. Iyo conductor yemhangura pachayo ndeye concentric stranding chimiro, iyo inonyanya kugadzirwa neyakajairwa furemu stranding muchina, forogo stranding muchina, nezvimwewo.
(2) XLPE tambo yekuvharisa kugadzirwa maitiro
Pakugadzirwa kweyakakwira voltage XLPE tambo, catenary dry cross-linking (CCV) uye vertical dry cross-linking (VCV) maviri ekugadzira maitiro.
(3) Extrusion process
Pakutanga, vagadziri vetambo vakashandisa yechipiri extrusion process kugadzira tambo yekuvharisa musimboti, danho rekutanga panguva imwe chete extrusion conductor nhovo uye insulation layer, uyezve yakabatana-yakabatana uye yakakuvara kune tambo tireyi, yakaiswa kwenguva yakati rebei extrusion. insulation shield. Mukati memakore ekuma1970, 1 + 2 matatu-layer extrusion process yakaonekwa mune insulated waya core, ichibvumira yemukati nekunze kudzivirira uye insulation kupedzwa mune imwechete maitiro. Iyo nzira inotanga kuburitsa nhovo yekondukita, mushure mechinguva chidiki (2 ~ 5m), uyezve inoburitsa iyo yekuvharisa uye nhovo yekudzivirira pane conductor nhovo panguva imwe chete. Nekudaro, nzira mbiri dzekutanga dzine zvipingamupinyi zvakakura, saka mukupera kwema1990, vatengesi vemagetsi ekugadzira matambo vakaunza matatu-layer co-extrusion yekugadzira maitiro, ayo akawedzera kudzivirirwa kwekondukita, insulation uye kudzivirira kwekudzivirira panguva imwe chete. Makore mashoma apfuura, nyika dzekune dzimwe nyika dzakatanga zvakare dhizaini nyowani yeextruder barrel uye yakakomberedzwa mesh ndiro dhizaini, nekuenzanisa screw yemusoro mhango kuyerera kudzvinyirira kudzoreredza kuunganidzwa kwezvinhu, kuwedzera nguva inoenderera yekugadzira, kutsiva iyo isingamire shanduko yezvakatemwa. iyo musoro dhizaini inogonawo kuchengetedza zvakanyanya kuderera kwemitengo uye kugadzirisa kushanda zvakanaka.
3. Mhedziso
Mota dzemagetsi nyowani dzine tarisiro yakanaka yekusimudzira uye musika muhombe, inoda nhevedzano yemhando yepamusoro yemagetsi tambo zvigadzirwa zvine yakakura kurodha simba, yakakwirira tembiricha kuramba, electromagnetic shielding effect, kukotama kuramba, kuchinjika, hupenyu hurefu hwekushanda uye kumwe kuita kwakanakisa mukugadzira uye kutora market. Mota yemagetsi yakakwira-voltage cable zvinhu uye maitiro ayo ekugadzirira ane tarisiro yakakura yebudiriro. Motokari yemagetsi haigone kuvandudza kushanda kwekugadzira uye kuve nechokwadi chekushandiswa kwekuchengetedza pasina yakakwirira-voltage tambo.
