Classification ntawm Insulator Strings

Suspension insulator strings tsuas yog haum rau cov yees ncaj (los yog nro ntauwd jumpers), ib qho kev ncua kev thaiv cov hlua. Nyob rau hauv ib txwm ua hauj lwm tej yam kev mob, nws tsuas dais lub ntsug thiab cua loads ntawm cov xov hlau thiab ntxiv loads. Thaum muaj xwm txheej, nws yuav tsum tiv taus qhov cuam tshuam ntawm cov hlau nro. Yog li ntawd, txoj hlua hluav taws xob raug ncua raws li ob qho tib si ib txhij.
Vim muaj qhov sib txawv ntsug loads, cov hlua khi hlua khi ntawm txhua theem tuaj yeem sib sau ua ke hauv ntau hom, xws li ib txoj hlua, ob txoj hlua, lossis ntau txoj hlua. Ib txoj hlua hluav taws xob thaiv hluav taws xob tau qhia. Kev siv ib txoj hlua insulator muaj ntau yam zoo: nws yuav tsum muaj tsawg dua cov khoom siv thiab cov insulators, yog li tus nqi qis dua; Tus nqi kev puas tsuaj kuj tseem qis dua, thiab tus nqi ntawm kev hloov, kev kho, thiab kev kho kuj raug txo; Vim muaj kev sib raug zoo ntawm qhov tshwm sim ntawm qhov tshwm sim ntawm flashover thiab tus naj npawb ntawm cov insulators thiab cov hlua, tus naj npawb ntawm cov insulators txo qis, uas ua rau txo qis qhov tshwm sim ntawm flashover.
Txawm li cas los xij, ib zaug ib txoj hlua insulator puas lawm, nws txoj kev ntseeg tau tsawg heev. Feem ntau, ob lossis ntau txoj hlua hluav taws xob tuaj yeem siv rau hauv qhov chaw uas muaj qhov loj, kev ntxhov siab hnyav, thiab qhov tseem ceeb spans. Sib dhos daim duab ntawm ob txoj hlua insulator. Tom qab siv ob txoj hlua insulator, txoj hlua ntev nce thiab cov pej thuam siab txo qis los ntawm 0.3-1M. Yog li ntawd, ib qho kev ncua sij hawm insulator cov hlua feem ntau yog siv, thiab tsuas yog thaum lub ntsug load loj thiab lub zog ntawm ib txoj hlua insulator tsis tuaj yeem ntsib, lossis ntawm qhov tseem ceeb, ob lossis ntau txoj hlua insulator yuav tsum tau siv. Qee zaum hauv thaj chaw roob, thaum lub kaum sab xis tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, ob txoj kab clamps kuj tau siv.
Kev soj ntsuam kev ntxhov siab ntawm cov hlua hluav taws xob nruj yog txawv kiag li ntawm cov hlua hluav taws xob ncua kev kawm. Nyob rau hauv ib txwm ua hauj lwm thiab kev khiav hauj lwm tej yam kev mob, ncua kev kawm ntawv insulator hlua tsuas yog dais ib ntsug load thiab tsis dais nto nro ntawm tus neeg xyuas pib. Ntawm qhov tsis sib xws, cov hlua hluav taws xob nro tuaj yeem cuam tshuam qhov nro ntawm tag nrho cov txheej txheem nyob ntawm tus neeg xyuas pib.
Zoo li cov hlua hluav taws xob raug tshem tawm, txoj kev xaiv rau cov ntsiab lus raug tshem tawm yuav tsum tau txiav txim siab tom qab txiav txim seb muaj pes tsawg tus insulator pob qij txha xav tau rau txhua txoj hlua insulator. Vim lub fact tias cov overlapping kab taw tes yog qhov chaw uas qhov kev nyuaj siab ntawm lub insulator txoj hlua yog concentrated, ib tug yooj yim qauv, hloov tau yooj yim kev sib hloov, yooj yim tsim, thiab clear stress overlapping kab txoj kev yuav tsum tau xaiv. Vim tias qhov no, txawm hais tias muaj ntau txoj hauv kev los dai cov kab hluav taws xob hluav taws xob, feem ntau muaj ob txoj hauv kev los dai lawv, ib qho yog square, thiab lwm qhov yog ob. Ob txoj hlua khi hlua tuaj yeem tig dawb do nce, nqis, sab laug, thiab sab xis, yog li ntawd, cov hlau dai cov qauv no tsis yog tsuas yog tsim nyog rau kev hloov ntawm lub kaum sab xis, tab sis kuj rau cov kev xav tau ntawm lub downward inclination lub kaum sab xis ntawm cov hlau hlau.
Muaj ntau hom V-shaped insulator sib dhos muaj rau kev kho thiab tshaj tawm. Kev siv cov V-shaped insulator hlua muaj qhov zoo hauv qab no: nws tuaj yeem txwv qhov oscillation ntawm cov hlua insulator, yog li txo qhov loj ntawm lub taub hau ntauwd; Txo qhov dav ntawm tsob ntoo txiav hauv thaj chaw hav zoov thiab txhim kho qhov kev khawb ntawm cov kab nqes hav hauv thaj chaw toj roob hauv pes hauv Suav teb tuaj yeem ua tiav los ntawm kev txo cov kev ncig xyuas txoj kev taug kev; Txo cov nyiaj txiag rau txoj kev yuav khoom thaum lub sij hawm tsim kab thiab txuag peev.
Ntawm qhov tod tes, siv V-shaped insulator hlua yuav muab ob npaug rau qhov yuav tsum tau rau cov insulators. Yog li ntawd, V-shaped insulator strings feem ntau yog siv rau ntauwd qhov rais thiab txwv rau nruab nrab theem conductors ntawm caw khob, qhov rooj, thiab miv taub hau hom. Yog tias siv rau theem sab, sab caj npab ntawm sab theem txuas ntxiv, tab sis nws tsis yog kev lag luam. Yog li ntawd, ib qho kev sib piv kev kawm thiab kev lag luam tau ua ua ntej siv V-shaped insulator hlua. V-shaped insulator hlua yog tsim nyog rau retrofitting qub kab los yog boosting kab.
