Niaj hnub no, peb yuav tham txog lub installation qhov ntev ntawm Rectangular Yoke Phaj. Cov qhov ntev no tsis yog arbitrary; lawv raug txiav txim los ntawm rau yam tseem ceeb: ntauwd qauv, insulator string type, conductor type thiab split spacing, mechanical load, on -site installation space, and electronics safe distances. Kev sib txawv ntawm qhov loj me no tuaj yeem ua rau txhua yam los ntawm kev sib dhos ua tsis tiav rau kev nyab xeeb loj xws li kev ntxhov siab tsis sib xws, kev co qaug zog, thiab flashover.
Lub installation qhov ntev ntawm Rectangular Yoke Phaj yuav tsum yog raws li cov kev qhia tshwj xeeb, uas yog qhov yuav tsum tau ua ua ntej rau kev xam qhov ntev. Peb lub tuam txhab feem ntau siv ntauwd kos duab los ntawm tus neeg siv, suav nrog ntauwd txoj kev npaj, insulator hanging point layout diagram, thiab crossarm structure diagram, ua lub hauv paus tseem ceeb rau kev txiav txim siab lub qhov sib nrug, qhov chaw nyob deb, thiab qhov chaw nruab. Qhov thib ob, cov kab hluav taws xob insulator yog qhov tseem ceeb: qhov chaw nruab nrab ntawm ob - strand insulators, qhov ntev ntawm kev sib txuas ntawm cov khoom siv, cov neeg xyuas pib, qhov chaw nruab nrab ntawm ob -split conductors, qhov sib txuas qhov ntev ntawm qhov nro clamps thiab ncua kev kawm ntawv clamps, thiab cov khoom ntsuas ntsuas, uas txiav txim siab lub phaj thickness, thiab bolt specifications.
Ib qho ua tiav ntawm cov khoom tsim tau thiab nruab tau Rectangular Yoke Phaj yuav tsum qhia cov nram qab no 12 qhov ntev, tsis muaj ib qho twg tuaj yeem raug tshem tawm: qhov nruab nrab ntawm qhov sib txuas ntawm qhov sib txuas, qhov nruab nrab ntawm qhov sib txuas ntawm tus neeg xyuas pib clamp qhov, tag nrho qhov ntev ntawm cov phaj txuas, tag nrho qhov dav ntawm cov phaj sib txuas, phaj thickness, txoj kab uas hla ntawm qhov sib txuas, qhov kev npaj, qhov loj thiab qhov chaw nyob ntawm qhov sib txuas ntawm cov phaj sib txuas, tag nrho qhov dav ntawm qhov sib txuas phaj, phaj thickness, txoj kab uas hla ntawm qhov sib txuas, qhov kev npaj, qhov loj thiab qhov chaw ntawm qhov sib txuas ntawm cov phaj sib txuas. thickness, bolt specifications thiab zawm torque, yam tsawg kawg nkaus hluav taws xob clearance thiab creepage nrug. Peb tam sim no yuav qhia txog cov no hauv kev nthuav dav.
Qhov chaw nruab nrab L ntawm qhov sib txuas ntawm cov qhov hluav taws xob yog qhov tseem ceeb tshaj plaws ntawm kev teeb tsa rau lub voj voos Yoke daim hlau. Nws feem ntau yog cim rau ntawm tus pej thuam crossarm hanging point daim duab lossis txiav txim siab los ntawm cov kab hluav taws xob insulator los txiav txim siab qhov chaw tsim qauv ntawm ob txoj hlua ntsug. Feem ntau qhov tseem ceeb yog 400 mm, 450 mm, 500 mm, thiab 600 mm. Rau kev kho dua tshiab, ntawm - qhov chaw ntsuas tuaj yeem ua tau los ntawm kev ntsuas qhov nruab nrab ntawm qhov chaw dai ntawm ob txoj hlua insulator. Peb qhov yuav tsum tau muaj tseeb yog ± 1 hli. Qhov kev ncua deb ntawm qhov sib txawv yuav ua rau cov hlua insulator qaij thiab cuam tshuam rau thaj tsam kev ntxhov siab.
Qhov chaw nruab nrab W ntawm qhov sib txuas ntawm tus neeg xyuas pib clamp yog qhov tseem ceeb ntawm kev txiav txim siab tus neeg xyuas pib sib piv. Nws yog siv rau qhov chaw nyob deb ntawm lub qhov nyob rau hauv nro clamps thiab ncua kev kawm ntawv clamps rau txuas ob -split conductors. Qhov sib txawv tsim ntawm ob -split conductors yog 400 mm, 450 mm, thiab 500 mm. Qhov loj me no yog txiav txim siab los ntawm kab hluav taws xob theem thiab tus neeg xyuas pib hom . 400 thiab 450 hli feem ntau siv rau 220 kV kab, thiab 450 thiab 500 hli feem ntau siv rau 330 kV ~ 500 kV kab. Lub qhov nrug W ntawm lub clamp yuav tsum ua kom zoo ib yam nrog lub qhov nrug ntawm lub cev clamp, txwv tsis pub sib dhos tsis tuaj yeem ua tau.
Tag nrho qhov ntev A thiab tag nrho qhov dav B kom ntseeg tau tias qhov chaw teeb tsa thiab hluav taws xob muaj kev nyab xeeb. Tag nrho qhov ntev A=insulator qhov sib nrug L + kev nyab xeeb ntawm ob qhov kawg, uas feem ntau yog 50 ~ 80 mm. Qhov no ua kom lub chaw teeb tsa thiab ua haujlwm, zam qhov ntse -Kho tawm ntawm qhov kawg, thiab ua tau raws li qhov yuav tsum tau muaj rau qhov chaw kho vajtse hoisting. Tag nrho qhov dav B=clamp qhov sib nrug W + sab sauv thiab qis kev nyab xeeb, uas feem ntau yog 40 ~ 60 hli. Yog tias nws yog qhov siab - qhov siab lossis thaj chaw muaj kuab paug hnyav, qhov loj yuav tsum tau nce ntxiv.
Lub thickness t ntawm Rectangular Yoke Phaj yog txiav txim los ntawm cov neeg kho tshuab load. Phaj thickness tsis yog tus nqi empirical, tab sis ncaj qha txiav txim siab los ntawm cov khoom siv ntsuas, thiab yog lub hauv paus ntawm lub zog thiab kev nyab xeeb. Tsis txaus thickness yuav ncaj qha ua rau tensile puas, khoov deformation, kev co qaug zog tawg, thiab lub thickness yuav tsum tau raws li qhov tsawg kawg nkaus kev puas tsuaj load yuav tsum tau los ntawm tus qauv.
Qhov sib txuas qhov taub D tuaj yeem ncaj qha nrog bolts thiab fittings. Yog tias txuas ncaj qha rau pob taub hau, khob taub hau, lossis UB mounting daim hlau, lub qhov taub yuav tsum nruj me ntsis phim tus pin txoj kab uas hla. Lub qhov taub txoj kab uas hla H12 ua kom zoo sib dhos thiab tiv thaiv kev tshem tawm ntau dhau.
Thaum xam qhov ntev ntawm Rectangular Yoke Phaj, yuav tsum ua tiav cov txheej txheem. Ua ntej, tag nrho cov ntaub ntawv yooj yim tau sau tseg, tom qab ntawd cov duab kos duab kos duab kos duab, quab yuam thiab kev kuaj xyuas hluav taws xob tau ua tiav, thiab cov duab kos tau lees paub nrog tus neeg siv ua ntej qhov kawg, kev tsim khoom, thiab kev xa khoom tuaj yeem pib.
