Pepalali limafotokoza makamaka mapangidwe a mzere wapamwamba, kusankha kwa chigawo chilichonse chofunikira, malo oyendetsa mzere ndi kuwerengera mzere ndi kuphatikiza kwa nyengo, njira zopangira mzere wapamwamba.Kumvetsetsa zazikulu magawo a makina ndi thupi katundu wa waya;Phunzirani mphamvu zamakina zanyengo pa makondakitala komanso mapangidwe amikhalidwe yazanyengo yophatikizana, ndikumvetsetsa momwe mayendetsedwe ake amayendera.

Kugawika ndi kapangidwe ka mizere yopatsira pamutu
1. Gulu la mizere yopatsira
Mzere wamagetsi ndi gawo lofunika kwambiri lamagetsi, lomwe limayang'anira kutumiza ndi kugawa mphamvu zamagetsi.Mizere yomwe imatumiza mphamvu zamagetsi kuchokera ku gwero kupita kumalo onyamula magetsi amatchedwa ma transmission lines.Pofuna kuchepetsa kutayika kwa mphamvu yamagetsi potumiza, mizere yotumizira imatenga magawo osiyanasiyana amagetsi malinga ndi mtunda wotumizira komanso mphamvu yotumizira.Pakalipano, magetsi osiyanasiyana omwe amagwiritsidwa ntchito ku China ndi 35, 60, 110, 220, 330, 500kV, ndi zina zotero. Ku China, mzere wa 35 ~ 220kV umatchedwa high voltage transmission line, ndipo mzere wa 330 ~ 500kV umatchedwa. ultra high voltage transmission line.Kuphatikiza apo, mzere womwe umayang'anira ntchito yogawa magetsi umatchedwa mzere wogawa.Miyezo yamagetsi ya mizere yogawa ku China ndi: 380V/220V, 6KV, 10KV, zomwe zimatanthawuza mizere yomwe ili pansi pa 1kV ngati mizere yamagetsi otsika kwambiri, mizere 1 ~ 10KV ngati mizere yogawa mphamvu yayikulu.
Mizere yotumizira imatha kugawidwa m'mizere ya chingwe ndi mizere yapamwamba molingana ndi kapangidwe kake.Poyerekeza ndi chingwe cha chingwe, mzere wapamwamba uli ndi ubwino wambiri woonekeratu, monga mawonekedwe osavuta, nthawi yomanga yochepa, mtengo wotsika wa zomangamanga, kukonza bwino, ntchito yabwino yowonongeka kwa kutentha, mphamvu yaikulu yotumizira ndi zina zotero.Pepalali limangopereka chidziwitso choyambirira cha mizere yotumizira ma voltage okwera kwambiri.
2. Mapangidwe a mizere yopatsira pamutu
Nthawi zambiri mizere yotumizira magetsi imagwiritsidwa ntchito kulumikiza mafakitale amagetsi a m'chigawo ndi masiteshoni ang'onoang'ono kumbali yolandirira.Kuti musunge mtunda wina pakati pa mawaya amoyo a mzere wotumizira mphamvu ndi pansi, gwiritsani ntchito mitengo ndi nsanja kuti muthandizire mawaya, monga momwe tawonetsera pa Chithunzi 1-1.Mtunda wopingasa pakati pa mizere yapakati ya nsanja zoyandikana umatchedwa mtunda wa gear.Gawo lokhazikika limapangidwa ndi mtunda wambiri pakati pa nsanja ziwiri zoyandikana.Monga momwe chithunzi #5 ~ #9, gawo lovutitsa limapangidwa ndi mtunda anayi.Ngati pali mtunda umodzi wokha mu gawo lovutitsa, limatchedwa lolekanitsidwa, monga momwe tawonetsera pachithunzi chapakati pa nsanja #9 ndi nsanja #10.Mzere wopatsirana nthawi zonse umakhala ndi magawo angapo opumira, kuphatikiza magawo akutali.

Mawu ena okhudzana ndi mizere yapamwamba
Choyamba, mawu ena ofunikira okhudzana ndi mapangidwe apamwamba amafotokozedwa motere:
(1) Kutalikirana kwa zida - Mtunda wopingasa pakati pa malo oyimitsidwa a mawaya pansanja ziwiri zoyandikana amatchedwa mtunda wa gear, womwe umasonyezedwa ndi, monga momwe tawonetsera pa Chithunzi 1-2.
(2) sag (kupumula) - mtunda pakati pa mfundo iliyonse ya waya ndi malo oyimitsidwa munjira yowongoka imatchedwa sag, yomwe imatchedwanso kupumula.
Nthawi zambiri, sag imatanthawuza kutsika kwakukulu mu giya imodzi pokhapokha ngati kutchulidwa kwina, ndipo kawirikawiri kumasonyezedwa ndi chilembo F, monga momwe tawonetsera pa Chithunzi 1-2.Pamene waya kuyimitsidwa mfundo ndi wofanana (okwera ndi ofanana), pazipita sag mu mtunda zida pakati;Pamene waya kuyimitsidwa mfundo si wofanana mu msinkhu (kukwera si wofanana), pazipita sag mu giya pafupifupi pakati pa giya mtunda.

(3) Malire - Mtunda wochepa wovomerezeka pakati pa waya ndi pansi umatchedwa malire, monga momwe H akuwonetsera pa Chithunzi 1-2.Mtengo wochepetsera mtunda umafotokozedwa mwatsatanetsatane m'malamulo aumisiri pakupanga mizere yotumizira ku Overhead ndi Malamulo aukadaulo pakupanga mizere yogawa pamwamba yomwe idaperekedwa ndi Unduna wa Zamagetsi zadziko lathu.Zigawo zazikulu za chingwe chotumizira chapamwamba ndi conductor, conductor mphezi, insulator, nsanja, chingwe ndi maziko.

Zigawo za mizere yotumizira pamutu

Timapereka kufotokozera mwachidule za ntchito zoyambira ndi mitundu ya zigawo za mabwalo apamwamba.

1, conductor

Mawaya amagwiritsidwa ntchito kunyamula mphamvu yamagetsi ndi magetsi.Nthawi zambiri, mizere yotumizira imagwiritsa ntchito kondakitala imodzi pagawo lililonse, koma pamagetsi apamwamba kwambiri komanso mizere yayikulu yotumizira mphamvu, kuti achepetse corona kuti achepetse kutayika kwamagetsi ndikuchepetsa kusokoneza kwa wailesi ndi TELEVISION, ma conductor agawidwe amagwiritsidwa ntchito kwambiri, ndiko kuti, awiri. , mawaya atatu, anayi kapena kuposerapo (kawirikawiri amaikidwa mu mphete) amagwiritsidwa ntchito.

2. Woyendetsa mphezi ndi thupi lapansi

Woyendetsa mphezi amapachikidwa pamwamba pa nsanjayo, ndipo amalumikizidwa ndi thupi loyatsira pansi kudzera pa waya wokhazikika pa nsanja iliyonse yoyambira.Pamene kutulutsa kwamtambo wamphezi kugunda mzere wamphezi, woyendetsa mphezi amakhala pamwamba pa kondakitala, ndipo mphezi yomwe ili pamwamba pake imatulutsidwa padziko lapansi.Mwanjira imeneyi, kuthekera kwa mphezi kugunda woyendetsa kumachepetsedwa, kutsekemera kwa mzere kumatetezedwa ku kuwonongeka kwa mphezi, ndipo chitetezo cha mphezi chimaperekedwa kuti zitsimikizire kuti mzerewo ukuyenda bwino.Pokhapokha pamwamba pa 110kV voltage grade line nthawi zambiri imakhazikitsidwa, zinthu zake nthawi zambiri zimakhala chingwe chachitsulo.

3, nsanja

Pulo tower imagwiritsidwa ntchito kuthandizira woyendetsa ndi woyendetsa mphezi ndi zowonjezera zake, ndikusunga mtunda wina wotetezeka pakati pa kondakitala, woyendetsa mphezi ndi nsanja, komanso pakati pa kondakitala ndi pansi ndi kudutsa zinthu kapena nyumba zina. .

4. Ma insulators ndi zingwe zotsekera

Ma insulators ndi zigawo zikuluzikulu za kusungunula kwa mzere, zomwe zimagwiritsidwa ntchito kuthandizira kapena kuyimitsa waya kuti atseke pansanja ndikuwonetsetsa kuti mzerewo uli ndi mphamvu yodalirika yamagetsi.Chifukwa sichimangokhala ndi mphamvu zamakina ndi mphamvu zamagetsi, komanso kupirira kukokoloka kwa mpweya woipa mumlengalenga.

Chifukwa chake, pamafunika kukhala ndi mphamvu zokwanira zamakina, mulingo wa insulation ndi kukana dzimbiri.

5, hardware

Zipangizo zolumikizira zingwe zimagwira ntchito yothandizira, kukonza ndi kulumikiza mawaya oteteza ndi mawaya oteteza mphezi mumizere yodutsa pamwamba.Ndipo akhoza kupanga mawaya olimba.Pali mitundu yambiri ya zopangira golide, zomwe zingagawidwe m'magulu asanu: chingwe cha waya, cholumikizira, chitetezo ndi kujambula waya molingana ndi katundu wawo ndi ntchito.

Pole tower maziko amakhazikika pansi kuonetsetsa kuti nsanjayo simapendekeka, kugwa, kutsika ndi zina.Ngati ndodo yolimbikitsidwa ya konkire imakwiriridwa m'nthaka, chifukwa gawo laling'ono la mtengowo ndi laling'ono, mtengowo udzamira m'nthaka.Panthawi imeneyi, pofuna kuteteza mzati kumira, nthawi zambiri pansi pa mzatiwo pali malo ambiri olimba a konkire - chassis, chassis ndi kuteteza maziko oti amire.Kumbali imodzi, ntchito ya chingwe ndi kupititsa patsogolo mphamvu ya nsanja, kunyamula katundu wakunja pa nsanja ya mphamvu, kuti achepetse kugwiritsidwa ntchito kwa nsanja;Komano, pamodzi ndi waya ndodo ndi thireyi waya, kukonza nsanja pansi, kuonetsetsa kuti nsanja si kupendekeka, kugwa.Maziko a Tower malinga ndi malo osiyanasiyana, geology ndi zomangamanga, mtundu womwe umagwiritsidwa ntchito ndi wosiyana.
