Classification ntawm insulators

Suspension insulator strings tsuas yog haum rau cov yees ncaj (los yog nro ntauwd jumpers) nrog ib qho kev ncua kev thaiv cov hlua. Nyob rau hauv ib txwm ua hauj lwm tej yam kev mob, lawv tsuas yog ris lub luj ntawm conductors thiab ntxiv ntsug loads thiab cua loads. Thaum muaj xwm txheej, lawv yuav tsum tiv taus qhov cuam tshuam ntawm tus neeg xyuas pib nruj. Yog li ntawd, ncua kev kawm ntawv insulator cov hlua ua tau raws li ob qho tib si ntawm cov xwm txheej no ib txhij.

Vim muaj qhov sib txawv ntsug loads, ncua kev kawm ntawv insulator cov hlua rau txhua theem tuaj yeem sib sau ua ke hauv ntau hom, xws li ib txoj hlua, ob txoj hlua, lossis ntau txoj hlua. Daim duab qhia tau hais tias ib qho kev ncua txoj hlua insulator. Kev siv ib txoj hlua ib leeg muaj ntau yam zoo: nws yuav tsum muaj tsawg dua fittings thiab insulators, uas ua rau cov nqi qis dua; qhov sib piv tsis ua hauj lwm tus nqi kuj qis dua, txo cov nqi ntawm kev hloov, tu, thiab kho; Qhov tshwm sim ntawm flashover yog ncaj qha proportional rau tus naj npawb ntawm cov insulators thiab cov hlua, yog li txo tus naj npawb ntawm cov insulators 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 qis. Feem ntau, ob lossis ntau txoj hlua hluav taws xob tuaj yeem siv rau hauv qhov chaw uas muaj qhov loj, muaj zog hnyav, thiab qhov tseem ceeb. Daim duab sib dhos rau ob txoj hlua insulator yog qhia. Los ntawm kev siv ob txoj hlua insulator, txoj hlua ntev nce, thiab qhov siab ntauwd txo los ntawm 0.3 mus rau 1 meter. Yog li ntawd, ib qho kev ncua sij hawm insulator cov hlua feem ntau yog siv, thiab ob los yog ntau cov hlua insulator tsuas yog yuav tsum tau thaum lub ntsug load siab thiab lub zog ntawm ib txoj hlua insulator tsis txaus, los yog ntawm qhov chaw tseem ceeb. Qee lub sij hawm, nyob rau hauv roob, ob-kab clamps kuj tau siv thaum lub kaum sab xis tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua.

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 tej yam kev mob, ncua kev kawm ntawv insulator hlua tsuas yog dais ib tug ntsug load thiab tsis dais lub nro ntawm tus neeg xyuas pib, thaum nro insulator hlua yog qhov opposite. Lawv tuaj yeem dais tag nrho kab rov tav nro ntawm tus neeg xyuas pib.

Zoo li cov hlua hluav taws xob raug tshem tawm, cov txheej txheem ntawm kev xaiv cov ntsiab lus ncua kev kawm 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. Txij li thaum cov ntsiab lus splicing yog qhov chaw uas muaj kev ntxhov siab nyob rau hauv cov hlua insulator, ib qho yooj yim, hloov tau, yooj yim rau nruab, thiab kev ntxhov siab-nrawm splicing txoj kev yuav tsum tau xaiv. Vim tias qhov no, txawm hais tias muaj ntau txoj hauv kev los tshem tawm cov kab hluav taws xob siv hluav taws xob, feem ntau muaj ob hom: square thiab ob npaug. Ob hom kev tshem tawm txoj kev tuaj yeem tig tau ywj pheej nyob rau hauv ob qho tib si ntsug thiab kab rov tav cov lus qhia, ua qhov kev ncua kev ncua tsis yog tsuas yog rau cov kev hloov ntawm cov kaum sab xis, tab sis kuj rau cov kev cai ntawm cov hlau inclination cov ces kaum.

V-shaped insulator sib dhos muaj ntau hom, thiab kev siv cov V-shaped insulator hlua muaj qhov zoo hauv qab no: nws tuaj yeem txwv lub viav vias ntawm cov hlua insulator, yog li txo qhov loj ntawm lub taub hau ntauwd; nws tuaj yeem txo qhov dav ntawm tsob ntoo txiav hauv thaj chaw hav zoov los ntawm kev nqaim txoj kev taug kev, thiab nws tuaj yeem txhim kho kev khawb ntawm qhov chaw siab tshaj ntawm cov roob roob hauv Suav teb; nws txo cov nyiaj yuav tsum tau rau txoj kev yuav khoom thaum lub sij hawm tsim kab, 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 hlua feem ntau yog siv rau ntauwd qhov rais, txwv rau khob-zoo li tus, portal, thiab miv taub hau hom ntawm theem conductors. Yog tias siv rau ntawm cov theem sab nraud, sab caj npab yuav txuas ntxiv, tab sis nws tsis yog kev lag luam, yog li kev sib piv kev lag luam thiab kev lag luam yog ua ntej siv V-shaped insulator hlua. V-shaped insulator hlua yog qhov tsim nyog rau kev kho dua tshiab lossis uprating ntawm cov kab uas twb muaj lawm.

Kev txhais lus:

Suspension insulator strings tsuas yog haum rau cov yees ncaj (los yog nro ntauwd jumpers) nrog ib qho kev ncua kev thaiv cov hlua. Nyob rau hauv ib txwm ua hauj lwm tej yam kev mob, lawv tsuas ris lub luj ntawm cov conductors
