Transmission line tower zvimiro zvirefu zvinoshandiswa pakufambiswa kwemagetsi emagetsi. Mamiriro avo ekuumbwa anonyanya kuenderana nemhando dzakasiyana dze spatial truss zvimiro. Nhengo dzeshongwe idzi dzinonyanya kuumbwa nesimbi imwechete equilateral angle kana simbi yakasanganiswa. Zvinhu zvinowanzo shandiswa ndezveQ235 (A3F) uye Q345 (16Mn).
Kubatana pakati pemitezo kunogadzirwa uchishandisa coarse bolts, iyo inobatanidza zvikamu kuburikidza neshear forces. Iyo shongwe yese inovakwa kubva kumakona simbi, inobatanidza mahwendefa esimbi, uye mabhaudhi. Zvimwe zvikamu zvega, senge shongwe base, zvinobatanidzwa pamwechete kubva kune akati wandei simbi mahwendefa kuti iite inoumbwa unit. Iyi dhizaini inobvumira kupisa-dip galvanization yekudzivirira ngura, kuita yekufambisa uye musangano wekuvaka kuve nyore.
Transmission line towers dzinogona kuverengerwa zvichienderana nechimiro chavo uye chinangwa. Kazhinji, ivo vakakamurwa kuita zvimiro zvishanu: semukombe, katsi-musoro wakaumbwa, wakatwasuka-umire, cantilever-shaped, uye barrel-shaped. Zvichienderana nebasa ravo, vanogona kuiswa mumatanho ekumanikidzana, shongwe dzakatwasuka, shongwe dzemakona, nhanho dzekuchinja-chikamu (pakuchinja chinzvimbo chemakondakita), shongwe dzekupedzisira, uye shongwe dzekuyambuka.
Straight-Line Towers: Aya anoshandiswa muzvikamu zvakatwasuka zvemitsara yekutapurirana.
Tension Towers: Aya akaisirwa kubata kunetsana mumakondakita.
Angle Towers: Izvi zvinoiswa panzvimbo iyo tambo yekufambisa inoshandura nzira.
Kuyambuka Towers: Shongwe dzepamusoro dzakamiswa pamativi ese echinhu chipi nechipi chinoyambuka kuti ive nechokwadi chekubvumidzwa.
Phase-Changing Towers: Idzi dzinoiswa nguva nenguva kuti dziyeredze kuvharika kwevatatu makondakita.
Terminal Towers: Aya ari panzvimbo dzekubatanidza pakati pemitsara yekufambisa uye zviteshi.
Mhando Dzinobva paZvishandiso
Transmission line shongwe dzinonyanya kugadzirwa kubva yakasimbiswa kongiri matanda uye simbi shongwe. Ivo vanogona zvakare kuverengerwa kuita shongwe dzinozvitsigira uye shongwe dzakashongedzwa zvichienderana nekugadzikana kwavo kwechimiro.
Kubva pamitsetse yekufambisa iripo kuChina, zvakajairika kushandisa shongwe dzesimbi kumazinga emagetsi ari pamusoro pe110kV, nepo mapango ekongiri akasimbiswa achiwanzo shandiswa kumazinga emagetsi ari pasi pe66kV. Guy waya dzinoshandiswa kuenzanisa mitoro yekumashure uye kukakavara mumakondakita, kuderedza nguva yekukotama pazasi peshongwe. Uku kushandiswa kwewaya dzevarume kunogonawo kuderedza kushandiswa kwezvinhu uye kuderedza mutengo wakazara wetambo yekufambisa. Guyed towers inonyanya kuwanda munzvimbo yakati sandara.
Kusarudzwa kwemhando yeshongwe uye chimiro kunofanirwa kuve kwakavakirwa pakuverenga kunosangana nezvinodiwa nemagetsi uchifunga nezve voltage level, nhamba yemasekete, terrain, uye geological mamiriro. Izvo zvakakosha kuti usarudze fomu reshongwe inokodzera iyo chaiyo purojekiti, pakupedzisira uchisarudza dhizaini iyo iri yese tekinoroji yepamusoro uye yehupfumi inonzwisisika kuburikidza nekuenzanisa ongororo.
Mitsetse yekufambisa inogona kukamurwa zvichibva panzira dzadzo dzekuisa kuita mitsara yekutapurirana pamusoro, tambo dzemagetsi tambo dzekutumira, uye gasi-insulated simbi-yakavharirwa tambo dzekutumira.
Overhead Transmission Lines: Aya anowanzo shandisa ma conductor asina kuvharirwa, anotsigirwa neshongwe dziri pasi, nemakondakita akamiswa kubva pashongwe achishandisa insulators.
Power Cable Transmission Lines: Aya anowanzo kuvigwa pasi pevhu kana kuiswa mumatambo etambo kana tunnels, anosanganisira tambo pamwe nemidziyo, yekubatsira, uye zvivakwa zvakaiswa patambo.
Gasi-Isulated Metal-Enclosed Transmission Lines (GIL): Iyi nzira inoshandisa simbi conductive tsvimbo yekutumira, yakavharirwa zvachose mukati megoko resimbi. Inoshandisa gasi rakamanikidzwa (kazhinji SF6 gasi) yekudzivirira, kuve nechokwadi kugadzikana uye kuchengeteka panguva yekufambisa ikozvino.
Nekuda kwemitengo yakakwira yetambo uye GIL, mitsetse yakawanda yekutapurirana parizvino inoshandisa mitsara yepamusoro.
Matanho ekutakurisa anogona zvakare kukamurwa nemazinga evoltage kuita yakakwira voltage, yakawedzera high voltage, uye Ultra-yakakwira voltage mitsetse. KuChina, mazinga emagetsi etambo dzekufambisa anosanganisira: 35kV, 66kV, 110kV, 220kV, 330kV, 500kV, 750kV, 1000kV, ±500kV, ±660kV, ±800kV, uye ± 10kV10.
Zvichienderana nerudzi rwezvino kufambisa, mitsetse inogona kuiswa mu AC uye DC mitsetse:
AC Lines:
High Voltage (HV) Mitsetse: 35 ~ 220kV
Extra High Voltage (EHV) Mitsetse: 330 ~ 750kV
Ultra High Voltage (UHV) Mitsetse: Pamusoro pe750kV
DC Lines:
High Voltage (HV) Mitsetse: ±400kV, ±500kV
Ultra High Voltage (UHV) Mitsetse: ± 800kV uye pamusoro
Kazhinji, kukura kwesimba rekufambisa simba remagetsi, ndiko kuwedzera kwevoltage yetambo inoshandiswa. Kushandisa ultra-high voltage transmission kunogona kunyatso kudzikisa kurasikirwa kwemitsara, kuderedza mutengo pachikamu chekutakura, kuderedza kugara kwevhu, uye kukurudzira kuchengetedza kwezvakatipoteredza, nekudaro kushandisa zvizere nzira dzekufambisa uye kupa zvakakosha zvehupfumi nemagariro.
Zvichienderana nehuwandu hwemaseketi, mitsetse inogona kuverengerwa se-single-circuit, double-circuit, kana multi-circuit mitsara.
Zvichienderana nechinhambwe chiri pakati pemakodhakita echikamu, mitsetse inogona kuiswa semitsetse yakajairwa kana mitsara yakabatana.
