Maumbirwo ewaya netambo anosanganisira kondakita, insulation, shielding, sheath nezvimwe zvikamu.
1. Muitisi webasa
Basa: Kondakita chikamu chewaya netambo zvinotumira simba remagetsi (magnetic), ruzivo uye zvinoita mabasa chaiwo ekushandura simba remagetsi.
Zvinhu: Kune mafambiro asina kuputirwa, akadai semhangura, aruminiyamu, mhangura, aruminiyamu; mafambiro ane simbi, akadai semhangura yakaputirwa mugaba, mhangura yakaputirwa nesirivha, mhangura yakaputirwa nenickel; mafambiro ane simbi, akadai sesimbi yakaputirwa nemhangura, aruminiyamu yakaputirwa nemhangura, simbi yakaputirwa nearuminiyamu, nezvimwewo.
2. Kudzivirira kupisa
Basa: Chidziviriro chekudzivirira chakaputirwa pamudziyo wemhepo kana chimwe chikamu chemudziyo wemhepo (senge tepi yemica inodzivisa kudonha kwemhepo), uye basa rayo nderekuparadzanisa mudziyo wemhepo kubva pakutakura voltage inoenderana nemagetsi uye kudzivirira kubuda kwemhepo.
Zvinhu zvinonyanya kushandiswa pakudzivirira kupisa zvinobuda mumhepo zvinosanganisira polyvinyl chloride (PVC), polyethylene (PE), cross-linked polyethylene (XLPE), polyolefin isina moto inodzima utsi (LSZH/HFFR), fluoroplastics, thermoplastic elasticity (TPE), silicone rabha (SR), ethylene propylene rabha (EPM/EPDM), nezvimwewo.
3. Kudzivirira
Basa: Chidziviriro chinoshandiswa muzvigadzirwa zvewaya netambo chine pfungwa mbiri dzakasiyana zvachose.
Chekutanga, chimiro chewaya netambo dzinotumira mafungu emagetsi ane frequency yakakura (senge radio frequency, tambo dzemagetsi) kana mafungu asina simba (senge tambo dzemasaini) chinonzi electromagnetic shielding. Chinangwa ndechekudzivirira kupindira kwemafungu emagetsi ekunze, kana kudzivirira masaini ane frequency yakawanda ari mutambo kuti asapindirane nenyika yekunze, uye kudzivirira kupindirana pakati pemawiri ewaya.
Chechipiri, maumbirwo etambo dzemagetsi dzepakati nepamusoro dzinoenzanisa simba remagetsi pamusoro pechinofambisa magetsi kana pamusoro pechinodzivirira magetsi anonzi electric field shielding. Kutaura chokwadi, simba remagetsi haridi basa re "kudzivirira", asi rinongoita basa rekuita kuti simba remagetsi rive homogeneous. Nhoo inoputira tambo inowanzo shandiswa pasi.
* Chimiro chekudzivirira electromagnetic nezvinhu
① Kudzivirira kwakarukwa: shandisa waya yemhangura isina chinhu, waya yemhangura yakaputirwa netini, waya yemhangura yakaputirwa nesirivha, waya yealuminium-magnesium alloy, tepi yemhangura yakatambarara, tepi yemhangura yakatambarara yakaputirwa nesirivha, nezvimwewo kuti zvirukwe kunze kwepakati pesimbi yakaputirwa, waya yesimbi kana core yetambo;
② Kudzivirira tepi yemhangura: shandisa tepi yemhangura yakapfava kufukidza kana kuputira yakatwasuka kunze kwepakati petambo;
③ Kudzivirira tepi yesimbi: shandisa tepi yearuminiyamu Mylar kana tepi yemhangura Mylar kuputira kana kuputira waya kana tambo yepakati;
④ Kudzivirira kwakazara: Kushandiswa kwakazara nenzira dzakasiyana dzekudzivirira. Semuenzaniso, putira waya dzemhangura (1-4) dzakatetepa dzakamira dzakatwasuka mushure mekuputira nearuminiyamu foil Mylar tape. Waya dzemhangura dzinogona kuwedzera simba rekudzivirira;
⑤ Chidziviriro chakasiyana + chidziviriro chose: waya yega yega kana boka rewaya dzakachengetedzwa nearuminiyamu foil Mylar tape kana waya yemhangura yakarukwa zvakasiyana, uye chimiro chekudzivirira chose chinowedzerwa mushure mekubatidza waya;
⑥ Chidziviriro chekuputira: Shandisa waya yemhangura yakatetepa, tepi yemhangura yakati sandara, nezvimwewo kuputira pakati pewaya yakaputirwa, waya yesimbi kana pakati pewaya.
* Chimiro chekudzivirira munda wemagetsi nezvinhu
Kudzivirira kwemuchina wemagetsi: Pamatambo emagetsi e6kV zvichikwira, jira rakatetepa rekudzivirira rinonamirwa pamusoro pemuchina wemagetsi uye pamusoro pemuchina wekudzivirira. Rudzi rwekudzivirira rwemuchina wemagetsi igwara rakaburitswa remuchina wekudzivirira. Kudzivirira kwemuchina wekudzivirira magetsi nechikamu che500mm² zvichikwira kunowanzo gadzirwa netepi yakaburitswa yemuchina wekudzivirira magetsi nechikamu chakaburitswa chemuchina wekudzivirira magetsi. Rudzi rwekudzivirira rwemuchina wekudzivirira magetsi igwara rakaburitswa;
Kuputira waya yemhangura: Waya yemhangura yakatenderera inonyanya kushandiswa pakuputira nedivi rimwe chete, uye chikamu chekunze chinoputirwa nekumashure uye chinosungirirwa netepi yemhangura kana waya yemhangura. Rudzi urwu rwechigadzirwa runowanzo shandiswa mutambo dzine magetsi mapfupi makuru, senge dzimwe tambo dzemagetsi dze35kV dzakakura. tambo yemagetsi ine core imwe chete;
Kuputira tepi yemhangura: kuputira netepi yemhangura yakapfava;
④ Corrugated aruminiyamu sheath: Inoshandisa hot extrusion kana aruminiyamu tape longitudinal wrapping, welding, embossing, nezvimwewo. Rudzi urwu rwekudzivirira runewo zvakanaka kudzivirira mvura, uye runonyanya kushandiswa patambo dzemagetsi dzine voltage yakawanda uye ultra-high-voltage.
4. Muhara
Basa remugodhi nderekuchengetedza tambo, uye musimboti ndewekuchengetedza insulation. Nekuda kwenzvimbo yekushandiswa inogara ichichinja, mamiriro ekushandiswa uye zvinodiwa nemushandisi. Saka, mhando, maumbirwo echivakwa uye zvinodiwa zvekushanda kwechimiro chemugodhi zvakasiyanawo, izvo zvinogona kupfupikiswa muzvikamu zvitatu:
Chimwe ndechekudzivirira mamiriro ekunze, dzimwe nguva masimba emakanika, uye jira rekudzivirira rinoda dziviriro yakajairika (sekudzivirira kupinda kweutsi hwemvura nemagasi anokuvadza); Kana paine simba guru rekunze remakanika kana kutakura huremu hwetambo, panofanira kunge paine chimiro chekudzivirira chejira resimbi resimbi; chechitatu chimiro chejira rekudzivirira chine zvinodiwa zvakakosha.
Saka, chimiro chemutanda wewaya netambo chinowanzo patsanurwa kuita zvikamu zviviri zvikuru: sheath (sleeve) nesheath yekunze. Chimiro chemutanda wemukati chakareruka, nepo sheath yekunze inosanganisira sheath yesimbi nesheath yayo yemukati (kudzivirira sheath yekudzivirira kuti isakuvadze sheath yemukati), uye sheath yekunze iyo inofanirwa kuchengetedza sheath yekudzivirira, nezvimwewo. Kune zvakasiyana-siyana zvinodiwa zvakaita semurazvo unodzivirira moto, kudzivirira moto, kudzivirira zvipembenene (termite), kurwisa mhuka (kurumwa nemakonzo, shiri), nezvimwewo, zvizhinji zvacho zvinogadziriswa nekuwedzera makemikari akasiyana-siyana musheath yekunze; zvimwe zvinofanirwa kuwedzera zvikamu zvinodiwa musheath yekunze.
Zvinhu zvinowanzoshandiswa ndeizvi:
Polyvinyl chloride (PVC), polyethylene (PE), polyperfluoroethylene propylene (FEP), polyolefin isina murazvo unopisa ine utsi hushoma (LSZH/HFFR), thermoplastic elastomer (TPE)
