Iri bepa rinonyanya kutsanangura magadzirirwo emutsetse wepamusoro, kusarudzwa kwechimwe nechimwe chikamu chinodiwa, mutsara unomhanya nharaunda uye mutsara kuverenga pamwe nekubatanidzwa kwemamiriro ekunze emamiriro ekunze, pamusoro pemutsetse dhizaini maitiro.Nzwisisa iwo makuru ma paramita emakanika uye emuviri zvimiro zvewaya;Iva nemeteorological pesvedzero yemeteorological mamiriro emamiriro ekunze uye kuumbwa kweakasanganiswa mamiriro emamiriro ekunze, uye unzwisise kuyerera kwekutanga kwedunhu dhizaini.
Kurongeka uye chimiro chemitsetse yekufambisa pamusoro
1. Kurongwa kwemitsara yekufambisa
Mutsara wemagetsi chikamu chakakosha chegadziriro yemagetsi, iyo inokonzera kutumira uye kugovera simba remagetsi.Mitsetse inofambisa simba remagetsi kubva kutsime kuenda kunzvimbo yemagetsi inonzi transmission lines.Kuti uderedze kurasikirwa kwesimba remagetsi munzira yekutapurirana, mitsara yekufambisa inotora mazinga akasiyana evoltage zvichienderana nenhambwe yekutapurirana uye simba rekutapurirana.Parizvino, mazinga akasiyana-siyana emagetsi anoshandiswa muChina 35, 60, 110, 220, 330, 500kV, nezvimwewo. MuChina, mutsara we35 ~ 220kV unonzi high voltage transmission line, uye mutsara we330 ~ 500kV unonzi. Ultra high voltage transmission line.Mukuwedzera, mutsara unotarisira basa rekugovera magetsi unonzi mutsara wekugovera.Mwero wevoltage wemitsara yekugovera yeChina ndeiyi: 380V/220V, 6KV, 10KV, zvinoreva mitsara iri pasi pe1kV semitsetse yakaderera-voltage yekugovera, 1 ~ 10KV mitsetse seyepamusoro-voltage yekugovera mitsetse.
Mitsetse yekutumira inogona kukamurwa kuita tambo dzetambo uye mitsara yepamusoro zvinoenderana nechimiro chavo.Kuenzaniswa netambo yetambo, mutsara wepamusoro une zvakawanda zvakanakira zviri pachena, senge chimiro chakareruka, nguva pfupi yekuvaka, mutengo wakaderera wekuvaka, kugadzirisa kuri nyore, kuita kwakanaka kwekupisa kupisa, hukuru hwekutakura uye zvichingodaro.Iri bepa rinongosuma chete ruzivo rwekutanga rweyakakwira voltage pamusoro pekutapurirana mitsara.
2. Maumbirwo emitsara yekufambisa pamusoro
Matanho ekutakurisa anowanzo shandiswa kubatanidza magetsi edunhu nezviteshi padivi rekugamuchira.Kuti uchengetedze chinhambwe pakati pewaya mhenyu yetambo yekufambisa simba uye pasi, shandisa mapango neshongwe kutsigira waya, sezvakaratidzwa mumufananidzo 1-1.Mufambo wakachinjika pakati pemitsetse yepakati peshongwe dziri pedyo unonzi nhambwe yegiya.A tensioning section inoumbwa nemafaro akati wandei pakati pema base towers maviri akatarisana.Sezvinoratidzwa mumufananidzo #5 ~ #9, iyo tensioning chikamu inoumbwa nemakiromita mana.Kana paine chinhambwe chimwe chete muchikamu chekumanikidzana, chinonzi chakasarudzika, sezvakaratidzwa mumufananidzo uri pakati peshongwe #9 neshongwe #10.Mutsetse wekutapurirana unogara wakaumbwa nezvikamu zvakawanda zvinonetsana, kusanganisira zvikamu zvakasarudzika.
Mamwe mazwi ane chekuita nemitsara yepamusoro
Chekutanga pane zvese, mamwe mazwi akakosha ane hukama nepamusoro mutsara chimiro anotsanangurwa sezvinotevera:
(1) Gear kureba - Iyo yakatwasuka nhambwe pakati penzvimbo dzakamiswa dzewaya pashongwe mbiri dziri padyo inonzi giya daro, iro rinowanzo kuratidzwa, sezvakaratidzwa mumufananidzo 1-2.
(2) sag (relaxation) - chinhambwe chiri pakati pechero poindi yewaya nenzvimbo yekumisikidza munzira yakatwasuka inonzi sag, inonziwo kuzorora.
Kazhinji, sag inoreva sag yakakura mugiya rimwe kunze kwekunge yatsanangurwa neimwe nzira, uye inowanzo ratidzwa netsamba F, sezvakaratidzwa mumufananidzo 1-2.Kana iyo waya yekumisa poindi yakaenzana (kukwira kwakaenzana), iyo yakanyanya sag mugiya chinhambwe pakati;Kana iyo yekumisa waya isina kuenzana muhurefu (kukwirira hakuna kuenzana), iyo yakanyanya sag mugiya inenge iri pakati pegiya chinhambwe.
(3) Muganhu - Iyo shoma inobvumirwa kureba pakati petambo uye pasi inonzi muganhu, sezvakaratidzwa naH muFigure 1-2.Kukosha kwekudzikamisa chinhambwe kunotsanangurwa zvakadzama mumirairo yehunyanzvi yekugadzirwa kweOverhead transmission mitsara uye Technical Regulations yekugadzira mitsara yekugovera pamusoro yakapihwa neBazi reMagetsi Simba renyika yedu.Izvo zvakakosha zvemutsetse wepamusoro wekufambisa mutsara ndeye conductor, mheni conductor, insulator, shongwe, tambo uye nheyo.
Zvikamu zvemitsara yekufambisa kwepamusoro
Isu tinopa tsananguro pfupi yemabasa ekutanga uye mhando dzezvikamu zvemaseketi epamusoro.
1, conductor
Waya dzinoshandiswa kutakura magetsi emagetsi nemagetsi.Kazhinji, mitsara yekufambisa inoshandisa imwechete conductor pachikamu chega chega, asi kune ekupedzisira yakakwira voltage uye mitsara yakakura yekutapurirana, kuitira kudzikisa corona kuderedza kurasikirwa kwemagetsi uye kuderedza kupindira kweredhiyo neTV, phase split conductors inonyanya kushandiswa, kureva maviri. , nhatu, ina kana kupfuura waya (kazhinji inogadziriswa mumhete) inoshandiswa.
2. Mheni conductor uye muviri wepasi
Iyo mheni conductor inoturikwa pamusoro pedanda reshongwe, uye yakabatana nemuviri wepasi kuburikidza newaya yepasi pane yega yega danda reshongwe.Kana gore remheni rinoyerera richirova mutsara wemheni, iyo mheni conductor inowanikwa pamusoro pe conductor, uye mheni yazvino pamusoro pevhu inoburitswa pasi.Nenzira iyi, mukana wemheni inorova conductor inoderedzwa, kusungirirwa kwemutsara kunodzivirirwa kubva mukukuvadzwa kwemheni yakawandisa, uye kudzivirirwa kwemheni kunopiwa kuti kuve nechokwadi chekushanda kwakachengeteka kwemutsara.Chete pamusoro pe110kV voltage giredhi mutsara unowanzo kusetwa, zvinhu zvayo zvinowanzo galvanized simbi tambo.
3, shongwe
Iyo pole tower inoshandiswa kutsigira conductor uye mheni conductor uye nemidziyo yayo, uye kuchengetedza imwe nzvimbo yakachengeteka pakati pe conductor, mheni conductor neshongwe, pamwe nepakati pe conductor nepasi uye kuyambuka zvinhu kana zvimwe zvivakwa. .
4. Insulators uye tambo dzekudzivirira
MaInsulators ndiwo akakosha ekuisa mutsetse, ayo anoshandiswa kutsigira kana kumisa waya kuti aiise kubva pashongwe uye kuona kuti mutsara une yakavimbika magetsi ekudzivirira simba.Nokuti haisi kungoiswa pasi pesimba remagetsi uye chiito chemagetsi, asiwo kutsungirira kukukurwa kwemagasi anokuvadza mumhepo.
Naizvozvo, zvinodikanwa kuve neyakakwana mechani simba, insulation level uye corrosion resistance.
5, hardware
Transmission line fittings inoita basa rekutsigira, kugadzirisa nekubatanidza waya dzedziviriro uye waya dzekudzivirira mheni mumitsetse yekutapurirana pamusoro.Uye inogona kuita kuti wiring ive yakasimba.Kune akawanda marudzi egoridhe fittings, ayo anogona kupatsanurwa muzvikamu zvishanu: wire clamp, yekubatanidza, kudzivirira uye kudhirowa kwewaya zvinoenderana nemidziyo yavo uye mashandisiro.
Pole tower hwaro yakamisikidzwa pasi kuti ive nechokwadi chekuti pole tower haina kurereka, kudonha, subsidence uye zvimwe zvivakwa.Kana yakasimbiswa kongiri tsvimbo yakananga kuvigwa muvhu, nokuti muchinjikwa chikamu nzvimbo danda diki, danda richanyura muuzhinji ivhu.Panguva ino kudzivirira danda kunyura, kazhinji pasi pedanda cushion nzvimbo yakakura yakasimbiswa kongiri ndiro - chassis, chassis ndiko kudzivirira danda kunyura hwaro.Kune rumwe rutivi, basa retambo nderokuvandudza simba reshongwe, kutakura mutoro wekunze kune simba reshongwe, kuitira kuti kuderedza kushandiswa kwezvinhu zveshongwe;Kune rumwe rutivi, pamwe chete netambo yewaya uye tireyi yewaya, kugadzirisa shongwe pasi, kuve nechokwadi kuti shongwe haina kurerekera, kudonha.Shongwe hwaro zvinoenderana nenzvimbo dzakasiyana, geology uye mamiriro ekuvaka, mhando inoshandiswa zvakare yakasiyana.
