Ingcaciso yeMveliso

Njengenxalenye ebalulekileyo yokufakelwa kwamandla ombane, ukusetyenziswa kweentonga ze-spacer zihlala zisetyenziswa kwiintambo zothumelo lwegridi yamandla yaseTshayina, kwaye imfuno yayo yokuvelisa iyanda.Ukuze kuthintelwe ukubetha phakathi kweengcingo kunye nokunciphisa ukungcangcazela kweengcingo ezibangelwa ngumoya, indima ye-spacer phakathi kweengcingo ibaluleke kakhulu, ifana nefuthe le-hammer anti-vibration, kodwa owona msebenzi uphambili ispacer kukucinezela ukungcangcazela phakathi kwespans .
I-spacer rod ibhekiselele kwizinto ezifakelweyo kwiingcingo eziqhekezayo ukulungisa umgama phakathi kweengcingo eziqhekezayo, ukuze kuthintelwe iingcingo ukuba zingatshayi omnye komnye, ukucinezela ukungcangcazela kwempepho kunye ne-sub-gap vibration.I-spacer ifakwe ngokubanzi phakathi kwe-span, kwaye enye ifakwe kwi-interval ye-50-60m.I-split-split, i-4-split, i-6-split, kunye ne-8-split-split wire spacer rods, xa kuthelekiswa ne-vibration amplitude yocingo oluqhekezayo emva kokufaka intonga ye-spacer kwaye ngaphandle kwe-spacer rod, i-wire-split wire iyancipha nge-50% , kwaye i-wire-split wire iyancipha ngama-87% kunye ne-90%.
Imfuno ephambili ye-spacer kukuba i-clamp kufuneka ibe ne-grip eyaneleyo kwaye ingakhululeki ngexesha lokusebenza kwexesha elide, kwaye amandla onke kufuneka akwazi ukumelana namandla e-centripetal yocingo ngalunye oluqhekezayo xa umgca ufutshane-ujikelezwe kwaye udinwe phantsi. ukungcangcazela kwexesha elide.I-spacer inokwahlulwa ibe ngamacandelo amabini: i-damping kunye ne-rigidity ngokwemigaqo yokusebenza.I-spacer yokudambisa ifakwe kunye nepedi yerabha engagugiyo kwiindawo zayo ezihambayo, kwaye isebenzisa ukuthotywa kwepedi yerabha ukuze idle amandla okungcangcazela komqhubi, ngaloo ndlela ivelisa impembelelo yokudambisa kwi-vibration ye-conductor..Izikhewu eziqinileyo ezingenazo iipads zerabha zidla ngokusetyenziswa kwiindawo apho ukungcangcazela kungekho lula ukwenzeka okanye kwi-jumper spacers ngenxa yokungasebenzi kakuhle kokufunxa ukungcangcazela.
I-spacer esidambisayo sisikhewu esithambileyo okanye esiqinileyo esinokuthi sinciphise ukungcangcazela kwempepho okanye ukungcangcazela kwesithuba esisezantsi somqhubi wokwahlulahlula.umzila wothumelo welizwe lam wama-500kV wamkela ulwakhiwo lwekhondatha oluzahlulo ezine.I-spacer iyona nto ifanelekileyo kwisakhiwo socingo oluqhekezayo.Imisebenzi esisiseko ye-spacer yile: ukuthintela ukubethelwa phakathi kweengcingo, ukucinezela ukungcangcazela kwempepho kunye nokungcangcazela kwe-sub-gap.Esona sisetyenziswa kakhulu sisithuba sokudambisa, esinokusebenza okungcono kokufunxa ukungcangcazela kunesikhewu esiqinileyo.Ke ngoko, uvavanyo lobungakanani bokusebenza kokufunxa ukungcangcazela kwesi spacer kube sisitshixo kuphando, uyilo, ukuvelisa kunye nokukhethwa kwesikhewu sokudambisa.

Iiparamitha zobugcisa

Iimpawu zemveliso kunye nenzuzo

1. I-spacer yokudambisa kunye ne-spacer engasimanzisi.Uphawu lwesi spacer sohlobo lokumanzisa kukuba irabha isetyenziswa njengesixhobo sokumanzisa kwindawo eshukumayo yesikhewu ukusebenzisa amandla okungcangcazela ocingo kwaye ivelise isiphumo sokudambisa intambo yocingo.Ke ngoko, olu hlobo lwe-spacer lufanelekile kuyo yonke imimandla.Nangona kunjalo, ngokuqwalasela uqoqosho lweentambo zothumelo lwamandla, olu hlobo lwe-spacer lusetyenziselwa imigca kwiindawo apho abaqhubi bathanda ukungcangcazela.I-spacer engathobekiyo ifunxa kakubi kwaye inokusetyenziswa kwimigca ekwiindawo apho ukungcangcazela kungekho lula ukwenzeka okanye ukusetyenziswa njenge-jumper spacer.
2. Iikhonduki ezimbini, ezine okanye ngaphezulu zisetyenziselwa umqhubi wesigaba ngasinye somgama omde kunye nomthamo omkhulu we-EHV transmission lines.Okwangoku, iintambo ze-220KV kunye ne-330KV zothumelo zisebenzisa ii-conductors ezimbini, ii-500KV iintambo zothumelo zisebenzisa ii-conductors ezintathu kunye ne-four-split conductors, kunye ne-ultra-high high voltage transmission lines kunye ne-voltage ephezulu kune-500KV isebenzisa ii-six-split kunye ne-conductor ezininzi eziqhekezayo.Ukuqinisekisa ukuba umgama phakathi kweentambo zocingo ezicandiweyo uhlala ungaguquguqukiyo ukuhlangabezana nokusebenza kombane, ukunciphisa ukuthambeka okunokubakho komphezulu, kwaye kwimeko yesekethe emfutshane, amandla ombane wombane awuzukwenziwa phakathi kweentambo zocingo, nto leyo ebangela umtsalane omnye komnye. kunye nongquzulwano, okanye nokuba ukungqubana komtsalane okukhawulezileyo kubangelwe, kodwa emva kokuba ingozi isusiwe Ngokukhawuleza ingabuyela kwimeko yesiqhelo, ngaloo ndlela iziphekepheke zifakwe kumgama othile kwisithuba.Ukufakwa kwee-spacer rods nako kunokudlala indima ethile ekuthinteleni ukungcangcazela kwesithuba sesibini kunye nokungcangcazela kwempepho.

Umgaqo wemveliso

Umgaqo-siseko wokusebenza we-spacer yokudambisa:
i-vibration yocingo olubangelwa yimpepho kunye ne-vibration ye-sub-gap eyenziwa ngumoya onamandla kuya kubangela ukukhathala kocingo, kwaye ukukhululeka kwe-fastener kuya kubangela ukuba ucingo lugqoke.Iingcingo eziqhekezayo zisebenzisa i-spacers ukwenzela ukusebenza okuzinzileyo kwe-electromechanical.I-spacer ye-damping kukusebenzisa i-elasticity ye-rubber element ukufumana ukuqina okufunekayo ukwenzela ukuba ibe nokuhamba okwaneleyo ngelixa igcina imilinganiselo yejometri yocingo oluqhekezayo.Sebenzisa i-viscosity yerabha ukufunxa amandla awoneleyo phantsi koxinzelelo olutshintshanayo ukufezekisa injongo yokucinezela ukungcangcazela komoya.
Ukusebenza kokudambisa kwe-spacer yokudambisa kunxulumene ne-coefficient yokumanzisa kwesixhobo serubha.Nangona kunjalo, umphumo wokudambisa into yerabha isondele ngakumbi kwisakhiwo kunye nesimo sokusetyenziswa kwe-spacer.Ukusebenza kokudambisa yipharamitha ephambili yophando kunye nokuyila izikhewu zokudambisa.Iimpawu zokufunxa ukungcangcazela kunye nokuqina kweentlobo ezahlukeneyo ze-spacers ezimanzi zinokuqikelelwa kwaye zithelekiswe ngokuvavanya ukuqina kwazo kunye nokusetyenziswa kwamandla.
Umgaqo wokuvavanya
ye-slider ye-damping spacer: Inkxaso yocingo lwenkxaso ye-spacer yokumanzisa idityaniswe nesilayida setafile yokungcangcazela efanisiweyo ukwenza isixhobo se-rocker slider, kwaye ukungcangcazela kwesilayida kusetyenziselwa ukulinganisa imeko yokusebenza ye-spacer yokumanzisa phezu kwentloko. ucingo.Vavanya umgca we-loop we-damping spacer rod kwi-overhead wire ukuxhasa i-amplitude yomgca wenkxaso oguqukayo kunye namandla angaphandle.Ummandla ovalelwe ngulo mgca we-loop yilahleko yamandla ngeveki.Ubunzima obuphakathi bubalwa ukusuka kumandla aphezulu angaphandle kunye ne-amplitude.
Indlela yokuchasa ukudanisa ye-clamp rotary spacer:
I-ice coating yocingo olulodwa kunye nocingo oluqhekezayo lwahluke kakhulu.I-axis yomgca wothumelo ngokuqhelekileyo i-eccentrically iced kwaye ijonge kwicala elibheke umoya.Emva kokuba i-conductor igqunywe ngumkhenkce, ukungalingani kobunzima kuya kujikeleza i-axis yayo.Ubume obunqamlezayo bomqhubi we-iced uba yinto efanayo ngexesha lenkqubo yokuguqulwa okuqhubekayo kunye nokugquma komkhenkce.Inefuthe lokucinezela ukugalopha kocingo.Ii-conductor eziqhekezayo zinezikhewu ngexesha lokulungisa i-sub-conductors, ukwenzela ukuba abaqhubi abancinci abakwazi ukujikeleza ngokufanelekileyo kufuphi neentonga ze-spacer.Ngexesha elifanayo, ngenxa yoxhulumaniso olusisigxina, ukuqina kwe-torsional ye-conductor encinci ye-gauge iyanda.I-sub-conductor ye-sub-gap idinga i-torque enkulu ye-static ukuba iguqulwe, kwaye kunzima ukuba umqhubi ajikeleze kwi-axis yayo.I-coefficient ye-torsion yocingo oluqhekezayo inkulu kakhulu kunocingo olulodwa, kwaye i-icing engalinganiyo ibaluleke kakhulu, ngoko ke ucingo oluqhekezayo luyakwazi ukugabavula kunocingo olulodwa.
Umthetho-siseko wokudanisa wokhuselo we-wire clamp rotary spacer: isibambiso socingo olujikelezayo sisitshixo sokukhusela ngokuchasene nokudanisa.Xa ii-sub-conductor zilungiswe kunye ne-spacers, isiqingatha se-sub-conductor sinokujikeleza ngaphakathi koluhlu oluthile.Nakwimeko ye-icing, abaqhubi banokusebenzisa i-eccentric mass egqunywe ngumkhenkce kunye nekhephu ukujija, kwaye benze ngokujija ii-axes zabo Ngokulinganayo ngokujikeleza kunye ne-icing.Ukuze kuphunyezwe injongo yokucinezela i-galloping egqunywe ngumkhenkce yocingo.
