Pasinei nepamusoro uye yakaderera mitsara yemagetsi pamwe nekuvharira otomatiki mitsara yekumusoro, kune kunyanya kunotevera kurongeka kwechikamu: mutsara danda, danda rekutapa, tension tsvimbo, terminal pole uye zvichingodaro.

The common pole structure classification:
(A)danda remutsara wakatwasuka- inonziwo yepakati danda. Gadzirisa mumutsara wakatwasuka, danda pamberi uye shure kwewaya yemhando imwe chete uye nhamba yakaenzana pamwe newaya kumativi maviri emakakatanwa akaenzana, chete mumutsara unoputsika kuti utsungirire kusawirirana kusingaenzaniswi kumativi ose.
(B) tension tsvimbo - mutsara unogona kuitika mukushanda kwekukanganisa kwemutsara uye kuita kuti shongwe imire kushushikana, kuitira kudzivirira kuwedzera kwekukanganisa, inofanira kuiswa mune imwe nzvimbo ine simba rakakura remagetsi, inokwanisa kumira. tension of the shongwe, shongwe iyi inonzi tension rod. Tsvimbo yekumanikidza inomisikidzwa munzira yemutsara, kuitira kuti iwe ugone kudzivirira kuparara kwemutsara, kukanganisa kunopararira kumutsara wese kumusoro, uye chete kusaenzana kwekunetseka kunongogumira kuhurumende pakati peiyo tambo yekumanikidza. Chinhambwe chiri pakati petsvimbo mbiri yekumanikidza inonzi tensioning chikamu kana tensioning giya chinhambwe, tambo refu dzemagetsi dzinowanzopa 1 kilometa yechikamu chekushushikana, asiwo zvinoenderana nemamiriro ekushanda kuti ave akakodzera kuwedzera kana kupfupisa. Munhamba yewaya uye chikamu chemuchinjiko chenzvimbo chakachinja, asiwo kushandisa tensioning tsvimbo.
(C)danda rekonashanduko mugwara remutsetse wepamusoro wenzvimbo, danda rekona rinogona kusagadzikana, rinogonawo kuve rakatsetseka, zvinoenderana neshongwe yakatakurwa netambo yekumanikidza.
(D)terminal pole - mutsara wepamusoro wekutanga uye wekupedzisira, nekuti danda rekupedzisira divi rimwe chete remutyairi, pasi pemamiriro ezvinhu akajairika zvakare rinofanira kutsungirira kushushikana, saka kuisa tambo.
Conductor type: steel-core aluminium stranded wire ine simba rakakwana remagetsi, yakanaka magetsi conductivity, lightweight, low price, corrosion resistance, inoshandiswa zvakanyanya mumagetsi epamusoro-soro emagetsi.
Iyo yakaderera-chikamu chemuchinjiko we conductor haisi pasi pe50mm² yekuzvivharira mitsara uye 50mm² kuburikidza nemitsara.
Line pitch: kusarudzwa kwepitch kwakakodzera kutora mapani ekugara nzvimbo 60-80m, nzvimbo dzisiri dzekugara 65-90m, asiwo zvinoenderana nemamiriro chaiwo pane saiti.
Conductor transposition: kondakita anofanirwa kutora chikamu chese chekuchinja, yega yega 3-4km shanduko, nguva yega yega yekumisikidza kutenderera kutenderera, mushure mekutenderera kutenderera, isati yaunzwa ye substation inofanira kuchengetedzwa mukusuma kwezviviri zvakavakidzana kugoverwa kweiyo. same phase line. Basa: kudzivirira kukanganiswa nekurukurirano yepedyo mitsetse yakazaruka uye mitsetse yezviratidzo; kudzivirira voltage yakawandisa.

Kurongeka kwetambo dzemagetsi epamusoro, ingave mitsetse yakakwira-voltage, mitsetse yakaderera-voltage kana otomatiki truncation mitsara, inogona kupatsanurwa mumhando dzinotevera: mapango akatwasuka, matanda akachinjika, matanda ekusunga uye mapango ekupedzisira.
1. Kurongwa kwezvakajairwa zvemagetsi pole zvimiro
Imwe mhando. Straight pole: Inozivikanwawo secenter pole, yakaiswa pachikamu chakatwasuka, kana mhando nenhamba yemaconductor zvakafanana, tension pamativi ese edanda yakaenzana. Inongomira chete kusawirirana kusingaenzaniswi kumativi ose apo conductor aputsa.
Inoiswa pachikamu chakatwasuka kana maconductor ari emhando imwechete uye nhamba. b. Tension Resistant Poles: Kana mutsara wadimburwa, mutsetse unogona kuiswa pasi pesimba rekumanikidza. Kuti udzivise kupararira kwezvikanganiso, zvakakosha kuisa matanda ane simba rakakwirira remagetsi uye anokwanisa kutsungirira kushushikana kune dzimwe nzvimbo, dzinonzi tension bars. Tension rods inopihwa mitsetse yetension padivi pemutsara kudzivirira kupararira kwezvikanganiso uye kuderedza kusawirirana pakati pematsimba maviri. Nhambwe iri pakati pematanho maviri etension inodaidzwa kuti tension section kana tension span, iyo inowanzoiswa pa 1 km kune tambo dzemagetsi refu, asi inogona kugadziriswa zvinoenderana nemamiriro ekushanda. Tension rods inoshandiswawo panosiyana nhamba necross-section yemaconductor.
c. Angle rods: Inoshandiswa sechinjo yenzvimbo yekumisikidza tambo dzemagetsi pamusoro. Mapango anogona kunge akatsikirirwa kana kuenzana. Kuiswa kwetension mitsara kunoenderana nekunetseka kwedanda.
d. Termination Posts: Inoshandiswa pakutanga uye pamagumo emutsetse wemagetsi wepamusoro. Kazhinji, rimwe divi reposvo rekupedzisira rinenge riri pasi petension uye rine tambo yetension.
Conductor Type: Aluminium core stranded wire (ACSR) inoshandiswa zvakanyanya mumagetsi akakwira pamusoro pemagetsi nekuda kwesimba rayo rakakwana remagetsi, kunaka kwemagetsi conductivity, huremu huremu, mutengo wakaderera uye kusagadzikana kwemarara. Pamitsetse ye10 kV pamusoro, makondukita akaiswa muzvikamu zvisina maconductor uye insulated conductors. Insulated conductors anowanzo shandiswa munzvimbo dzine masango nenzvimbo dzisina kukwana pasi pevhu.
Conductor cross-section: Steel-core aluminium stranded waya dzine diki diki-chikamu-chikamu chisingasviki 50mm² anowanzo shandiswa pakuzvivhara wega uye kuburikidza nemitsara.
Mutsara kureba: Nharaunda pakati pemitsetse munzvimbo dzekugara dzakafuratira ndeye 60-80m, uye kureba pakati pemitsetse munzvimbo dzisiri dzekugara ndeye 65-90m, iyo inogona kugadziridzwa zvinoenderana nemamiriro chaiwo pane saiti.
Kudzoserwa kwemutyairi: Kondakita anofanirwa kudzoserwa kumashure kwese kwese kwemakiromita 3-4, uye kutenderera kutenderedza kunofanirwa kuisirwa chikamu chimwe nechimwe. Mushure mekutenderera kutenderera, chikamu cheyakavakidzana substation feeder chinofanirwa kunge chakafanana nechikamu chisati chaiswa chiteshi. Izvi ndezvekudzivirira kuvhiringidza kutaurirana kuri pedyo uye mitsetse yemasaini uye kudzivirira overvoltage.
