Monga gawo lofunikira la zopangira magetsi, kugwiritsa ntchito ndodo za spacer kumagwiritsidwa ntchito pafupipafupi pamizere yotumizira magetsi ku gridi yamagetsi yaku China, ndipo kufunikira kwake kukukulirakulira.Pofuna kupewa kukwapula pakati pa mawaya ndi kuchepetsa kugwedezeka kwa mawaya omwe amachititsidwa ndi mphepo yamkuntho, udindo wa spacer pakati pa mawaya ndi wofunika kwambiri, mofanana ndi zotsatira za nyundo yotsutsa kugwedezeka, koma ntchito yaikulu ya spacer ndi kuletsa kugwedezeka pakati pa spans.
Ndodo ya spacer imatanthawuza zopangira zomwe zimayikidwa pa mawaya ogawanika kuti akonze mtunda pakati pa mawaya ogawanika, kuti ateteze mawaya kukwapula wina ndi mzake, kupondereza kugwedezeka kwa mphepo ndi kugwedezeka kwapakati.Spacer nthawi zambiri imayikidwa pakati pa danga, ndipo imodzi imayikidwa pakapita nthawi ya 50-60m.Zigawo ziwiri, zogawanika zinayi, zisanu ndi chimodzi, ndi zisanu ndi zitatu zogawanitsa waya, poyerekeza ndi kugwedezeka kwa matalikidwe a waya wogawanika mutatha kuyika ndodo ya spacer ndipo popanda ndodo ya spacer, waya wogawanikawo amachepetsedwa ndi 50% , ndipo waya wogawanika anayi amachepetsedwa ndi 87% ndi 90%.
Chofunikira chachikulu cha spacer ndikuti chowongoleracho chiyenera kukhala chogwira mokwanira ndipo sichiyenera kumasuka pakapita nthawi yayitali, ndipo mphamvu yonseyo iyenera kupirira mphamvu yapakati pa waya uliwonse wogawanika pamene mzere uli wozungulira komanso kutopa pansi. kugwedezeka kwa nthawi yayitali.The spacer akhoza kugawidwa m'magulu awiri: damping ndi rigidity malinga ndi ntchito.The damping spacer imaphatikizidwa ndi mphira wosamva kuvala m'zigawo zake zosuntha, ndipo imagwiritsa ntchito damping pad ya rabara kuti iwononge mphamvu yakugwedezeka kwa kondakitala, potero imatulutsa mphamvu pakugwedezeka kwa kondakitala..Ma spacers olimba opanda mapepala oterowo nthawi zambiri amagwiritsidwa ntchito m'malo omwe kugwedezeka sikophweka kuchitika kapena ma jumper spacers chifukwa cha kusagwira bwino ntchito kwa mayamwidwe.

Zosintha zaukadaulo

Zogulitsa katundu ndi ubwino

1. Damping spacer ndi si damping spacer.Makhalidwe a spacer yamtundu wonyowa ndikuti mphira umagwiritsidwa ntchito ngati chonyowetsa pamalo osunthika a spacer kuti adye mphamvu yakugwedezeka kwa waya ndikupangitsa kuti pakhale kugwetsa kugwedezeka kwa waya.Choncho, mtundu uwu wa spacer ndi woyenera kumadera onse.Komabe, poganizira za chuma cha mizere yotumizira mphamvu, mtundu uwu wa spacer umagwiritsidwa ntchito makamaka pamizere m'malo omwe ma conductor amakonda kugwedezeka.Chombo chopanda damping sichimayamwa bwino ndipo chimatha kugwiritsidwa ntchito pamizere yomwe kugwedezeka sikophweka kapena kugwiritsidwa ntchito ngati jumper spacer.
2. Awiri, anayi kapena kuposerapo ogawanika kondakitala ntchito gawo lililonse kondakitala wa mtunda wautali ndi lalikulu mphamvu EHV mizere kupatsira.Pakali pano, mizere yotumizira 220KV ndi 330KV imagwiritsa ntchito ma kondakitala ogawanika awiri, mizere yotumizira 500KV imagwiritsa ntchito makondakitala ogawanika atatu ndi anayi, ndipo ma ultra-high voltage transmissions okhala ndi ma voltages apamwamba kuposa 500KV amagwiritsa ntchito ma conductors ogawanika asanu ndi limodzi ndi ochulukirapo.Pofuna kuwonetsetsa kuti mtunda pakati pa ma waya ogawanika umakhalabe wosasinthika kuti ugwirizane ndi mphamvu zamagetsi, kuchepetsa kukwera kwapamwamba, ndipo ngati kuli kozungulira pang'ono, mphamvu yamagetsi yamagetsi sidzapangidwa pakati pa ma waya, zomwe zimayambitsa kukopana. ndi kugundana, kapena ngati kugunda nthawi yomweyo kukopa kuyambika, koma ngoziyo itathetsedwa Mwamsanga akhoza kubwerera ku mkhalidwe wabwinobwino, potero ndodo za spacer zimayikidwa pamtunda wina wake.Kuyika kwa ndodo za spacer kungathenso kuchitapo kanthu poletsa kugwedezeka kwa nthawi yachiwiri ndi kugwedezeka kwa mphepo.

Mankhwala mfundo

Mfundo yogwira ntchito ya damping spacer:
kugwedezeka kwa waya komwe kumachitika chifukwa cha mphepo yamkuntho ndi kugwedezeka kwa gawo laling'ono lopangidwa ndi mphepo yamphamvu kumapangitsa kuti waya atope, ndipo kutayikira kwa chomangira kumapangitsa waya kuvala.Mawaya ogawanika amagwiritsa ntchito ma spacers kuti agwire bwino ntchito yamagetsi.The damping spacer ndi ntchito elasticity wa chinthu mphira kupeza rigidity chofunika kuti athe kuyenda mokwanira pamene kusunga miyeso ya geometric wa waya ogawanika.Gwiritsani ntchito mamasukidwe akayendedwe a rabara kuti mutenge mphamvu zokwanira posinthana kupsinjika kuti mukwaniritse cholinga choletsa kugwedezeka kwa mphepo.
Kuchita konyowa kwa spacer yonyowa kumayenderana ndi kunyowa kwa chinthu cha rabara.Komabe, kunyowetsa kwa chinthu cha rabara kumagwirizana kwambiri ndi kapangidwe kake ndi mawonekedwe a spacer.Kuchita konyowa ndi gawo lofunikira pakufufuza ndi kupanga ma spacers ocheperako.Mayamwidwe a vibration ndi kulimba kwa mitundu yosiyanasiyana ya ma spacers onyowa amatha kuyerekezedwa ndikufanizidwa poyesa kuuma kwawo komanso kugwiritsa ntchito mphamvu.
Mfundo yoyesera
wa damping spacer: Thandizo lawaya lothandizira la damping spacer limalumikizidwa ndi slider ya tebulo logwedezeka lofananira kuti lipange makina owongolera a rocker, ndipo kugwedezeka kwa slider kumagwiritsidwa ntchito kufananiza momwe ntchito yonyowa imachitikira pamwamba. waya.Yesani mzere wozungulira wa ndodo ya damping spacer pawaya wapamwamba kuti muthandizire kukula kwa mzere wothandizira kusintha ndi mphamvu yakunja.Dera lomwe lazunguliridwa ndi mzerewu ndilowonongeka kwa mphamvu sabata iliyonse.Kuuma kwapakati kumawerengedwa kuchokera ku mphamvu yaikulu yakunja ndi matalikidwe.
Makina odana ndi kuvina a clamp rotary spacer:
Kupaka ayezi wa waya umodzi ndi waya wogawanika ndi wosiyana kwambiri.Mzere wa mzere wotumizira nthawi zambiri umakhala wozizira kwambiri ndipo umayang'ana mbali yamphepo.Kondakitala atakutidwa ndi ayezi, kusalinganika kwakukulu kumazungulira kuzungulira kwake.Mawonekedwe amtundu wa iced conductor amakhala yunifolomu panthawi ya kupotoza kosalekeza ndi kuyanika kwa ayezi.Zimakhala ndi zotsatira za kupondereza kuthamanga kwa waya.Ma conductors ogawanika amakhala ndi ma spacers pakapita nthawi kuti akonze ma sub-conductors, kotero kuti ma conductors sangathe kuzungulira molingana ndi ndodo za spacer.Pa nthawi yomweyi, chifukwa cha kugwirizana kosasunthika, kukhazikika kwa torsional kwa mini-gauge conductor wamfupi kumawonjezeka.The sub-conductor of the sub-gap imafuna torque yayikulu yokhazikika kuti itembenuzidwe, ndipo ndizovuta kuti kondakitala azizungulira kuzungulira kwake.The torsion coefficient of the split wire ndi yaikulu kwambiri kuposa ya waya umodzi, ndipo icing yosagwirizana ndi yoopsa kwambiri, kotero kuti waya wogawanika amatha kudumpha kuposa waya umodzi.
Mfundo yovina yovina ya wire clamp rotary spacer: chingwe chozungulira chawaya ndiye chinsinsi chodziteteza ku kuvina.Pamene ma-conductors amaikidwa ndi ma spacers, theka la ma-conductors amatha kuzungulira mkati mwamtundu wina.Ngakhale pankhani ya icing, ma conductor amathanso kugwiritsa ntchito madzi oundana oundana ndi chipale chofewa kuti azipotokola, ndikupanga pozungulira nkhwangwa zawo Molingana mozungulira ndi icing.Kuti akwaniritse cholinga chopondereza kuthamanga kwa waya kwakutidwa ndi ayezi.
