Iyo yakakosha chimiro chewaya uye tambo inosanganisira conductor, insulation, kudzivirira, sheath uye zvimwe zvikamu.
1. Muitisi
Basa: Conductor chikamu chewaya uye tambo inofambisa magetsi (magnetic) simba, ruzivo uye inoona chaiwo mabasa emagetsi ekushandura simba.
Material: Kune kunyanya isina kuvharwa conductors, semhangura, aluminium, copper alloy, aluminium alloy; simbi-yakavharidzirwa conductors, yakadai semhangura yakakanyiwa, sirivha-yakaputirwa mhangura, nickel-plated mhangura; simbi-yakapfeka makondukita, akadai semhangura-yakapfeka simbi, mhangura-yakapfeka aluminium, aruminiyamu yakavharwa simbi, nezvimwe.
2. Insulation
Basa: Iyo insulating layer yakaputirwa yakatenderedza conductor kana iyo yekuwedzera layer ye conductor (senge refractory mica tepi), uye basa rayo nderekuparadzanisa conductor kubva pakutakura inoenderana voltage uye kudzivirira kuvuza ikozvino.
Zvinhu zvinowanzo shandiswa pakuisa extruded insulation ndeye polyvinyl chloride (PVC), polyethylene (PE), cross-linked polyethylene (XLPE), low-smoke halogen-free flame retardant polyolefin (LSZH/HFFR), fluoroplastics, thermoplastic elasticity (TPE), Silicone rubber (SR), ethylene propylene rubber (EPM/EPDM), nezvimwewo.
3. Kudzivirira
Basa: Iyo shielding layer inoshandiswa muwaya uye tambo zvigadzirwa zvine maviri akasiyana pfungwa.
Chekutanga, chimiro chewaya uye tambo dzinofambisa mafungu emagetsi emagetsi epamusoro-soro (akadai seredhiyo, tambo dzemagetsi) kana mafambiro asina simba (senge tambo dzechiratidzo) anodaidzwa kuti electromagnetic shielding. Chinangwa ndechekuvhara kupindira kwemafungu emagetsi ekunze, kana kudzivirira masaini epamusoro-frequency mutambo kuti asapindirane nekunze kwenyika, uye kudzivirira kupindirana pakati pewaya peya.
Chechipiri, chimiro chepakati nepamusoro tambo dzemagetsi emagetsi kuti aenzane nemunda wemagetsi pane conductor surface kana insulating surface inonzi electric field shielding. Kunyatsotaura, kuchengetedzwa kwemagetsi hakudi basa re "kudzivirira", asi rinongoita basa rekuita homogenizing munda wemagetsi. Iyo nhovo inoputira tambo inowanzoiswa pasi.
* Electromagnetic shielding chimiro uye zvinhu
① Yakarukwa nhovo: kunyanya shandisa waya yemhangura isina chinhu, tin-plated tambo yemhangura, sirivheri-yakavharidzirwa mhangura waya, aluminium-magnesium alloy waya, mhangura flat tape, siri-plated copper flat tape, nezvimwewo kuti irukwe kunze kweiyo insulated core, waya. pair kana cable core;
② Tepi yemhangura inodzivirira: shandisa tepi yakapfava yemhangura kuvhara kana kuputira vertically kunze kwetambo yepakati;
③ Metal composite tepi kudzivirira: shandisa aruminiyamu foil Mylar tepi kana yemhangura foil Mylar tepi yekuputira kana vertically kuputira waya peya kana tambo yepakati;
④ Comprehensive shielding: Comprehensive application by different forms of shielding.Semuyenzaniso, putira (1-4) waya dzakatetepa dzemhangura dzakadzika mushure mekuputirwa nealuminium foil Mylar tape. Waya dzemhangura dzinogona kuwedzera conduction mhedzisiro yekudzivirira;
⑤ Yakaparadzana shielding + yakazara shielding: imwe neimwe yewaya peya kana boka rewaya inodzivirirwa nealuminium foil Mylar tape kana waya yemhangura yakarukwa zvakasiyana, uye ipapo iyo yakazara nhovo chimiro inowedzerwa mushure mecabling;
⑥ Kuputira nhovo: Shandisa waya yakatetepa yemhangura, tepi yemhangura yakatsetseka, nezvimwewo kuputira simbi yakavharidzirwa musimboti, waya peya kana tambo core.
* Magetsi munda wekudzivirira chimiro uye zvinhu
Semi-conductive shielding: Kune tambo dzemagetsi dze6kV uye pamusoro, yakatetepa semi-conductive nhovo yekudzivirira inosungirirwa kune conductor pamusoro uye insulating pamusoro. Iyo conductor shielding layer ndeye extruded semi-conductive layer. Conductor anodzivirira ane muchinjiko-chikamu che500mm² uye pamusoro anowanzo kuumbwa semi-conductive tepi uye extruded semi-conductive layer. Iyo insulating shielding layer is extruded structure;
Kuputira waya yemhangura: Waya yemhangura yakatenderedzwa inonyanya kushandiswa pakuputira-inonamirana, uye iyo yekunze dhizaini yakakuvadzwa neshure uye yakasungirirwa tepi yemhangura kana waya yemhangura. Rudzi urwu rwechimiro chinowanzo shandiswa mumatambo ane hombe-pfupi-yedunhu ikozvino, semamwe makuru-chikamu 35kV tambo. single-core power cable;
Kuputira tape yemhangura: kuputira nematepi emhangura yakapfava;
④ Corrugated aluminium sheath: Inotora inopisa extrusion kana aluminium tape longitudinal wrapping, welding, embossing, etc. Mhando iyi yekudzivirira inewo yakanakisa kudzivirira mvura, uye inonyanya kushandiswa kune yakakwirira-voltage uye Ultra-yakakwirira-voltage magetsi tambo.
4. Sheath
Basa re sheath nderokudzivirira tambo, uye musimboti ndeyekudzivirira iyo yekuvharisa. Nekuda kweiyo inogara ichichinja nharaunda yekushandisa, mamiriro ekushandisa uye zvinodiwa nemushandisi. Naizvozvo, iwo marudzi, mafomu ekuumbwa uye mashandiro ekuita kweiyo sheathing chimiro zvakare akasiyana, ayo anogona kupfupikiswa muzvikamu zvitatu:
Imwe ndeyekuchengetedza kunze kwemamiriro ekunze ekunze, dzimwe nguva mechanical masimba, uye general protective layer inoda kuchengetedzwa kwechisimbiso (sekudzivirira kupindira kwemhute yemvura uye magasi anokuvadza); Kana paine simba guru rekunze remagetsi kana kutakura huremu hwetambo, panofanira kunge kune gadziriro yekudzivirira yesimbi yesimbi; chechitatu ndiyo inodzivirira layer structure ine zvakakosha zvinodiwa.
Naizvozvo, iyo sheath chimiro chewaya uye tambo inowanzo patsanurwa kuita zvikamu zviviri zvikuru: sheath (sleeve) uye kunze sheath. Chimiro chemukati sheath chiri nyore, nepo sheath yekunze inosanganisira simbi yezvombo zvesimbi uye yemukati yemukati yemukati (yekudzivirira iyo yezvombo dhizaini kubva mukukuvadza yemukati sheath layer), uye yekunze sheath inodzivirira nhumbi dzezvombo, nezvimwe. .Kune zvakasiyana-siyana zvinodiwa zvakadai semurazvo wemoto, kudzivirira moto, anti-insect (termite), anti-mhuka (kuruma makonzo, shiri peck), nezvimwewo, zvizhinji zvacho zvinogadziriswa nekuwedzera makemikari akasiyana-siyana kune kunze; vashoma vanofanirwa kuwedzera zvinodikanwa mune yekunze sheath chimiro..
Zvishandiso zvinonyanya kushandiswa ndezvi:
Polyvinyl chloride (PVC), polyethylene (PE), polyperfluoroethylene propylene (FEP), low smoke halogen free flame retardant polyolefin (LSZH/HFFR), thermoplastic elastomer (TPE)
