2 、 Khoom taw qhia

Fcrgj kua nplaum impregnated fiber ntau capacitive phab ntsa bushing maj mam txo cov high voltage los ntawm lub capacitive voltage faib txoj cai. Nyob rau hauv ib txwm ua haujlwm, qhov kawg screen txhuas yog sib npaug rau flange thiab grounded los ntawm flange. Yog li ntawd cov hlau lead high-voltage tuaj yeem hla ntawm phab ntsa lossis hauv pem teb kom nyab xeeb thiab ua si lub luag haujlwm ntawm kev rwb thaiv tsev thiab txhawb kev sib txawv.

Nws yog tsim los ntawm thawj winding, txheej sheath, silicone roj hmab kaus tiab, siab equalizing npog ntawm ob hnub, flange thiab conductive hlau clamp.

3. Phab ntsa bushing

Piv txwv li, lub ntsiab lus ntawm fcrgj-24 / 3150: roj hmab impregnated fiber ntau capacitive phab ntsa bushing nrog ntsuas voltage ntawm 24kV thiab ntsuas tam sim no ntawm 3150A.

Lub ntsiab lus ntawm fcrgj-252 / 2500: kua nplaum impregnated fiber ntau capacitive phab ntsa bushing nrog ntsuas voltage ntawm 252kV thiab ntsuas tam sim no ntawm 2500A.

4, Siv tej yam kev mob:

1. Ambient cua kub: ambient kub: siab tshaj 55 ℃, yam tsawg kawg nkaus - 60 ℃.

2. Kev xaiv ntawm creepage tshwj xeeb nyob deb yuav tsum ua raws li cov kev cai ntawm GB / T 5582.

Creepage tshwj xeeb nrug yog muab faib ua 4 theem:

Chav Kawm I: 16mm / kV; Chav Kawm II: 20mm / kV; Chav Kawm III: 25mm / kV; Qib IV: 31 mm / kV

Qhov kev tso cai tsis zoo ntawm qhov tseeb creepage deb ntawm bushing yog 0.04l + 1.5mm (L: yam tsawg kawg nkaus nominal creepage nrug).

Thaum tus neeg siv tsis muaj qhov yuav tsum tau ua, lub neej ntawd yog 31mm / kV

5 、 Main technical parameters ntawm cov khoom

1. Table 1 muab qhov ntsuas voltage, qhov system ua haujlwm voltage, ntsuas tam sim no, qib rwb thaiv tsev thiab lwm yam tsis muaj fcrgj hom phab ntsa bushing.

2. Nyob rau hauv qhov voltage ntawm 1.05ur / √ 3 thiab ur, lub dielectric poob qhov tseem ceeb TG δ ≤0.4%.

3. Lub peev xwm tso tawm hauv zos: ≤ 5pc nyob rau hauv qhov ntsuas hluav taws xob ntawm 1.05ur / √ 3.

4. Kub nce ≤ 60K, lub sijhawm ua haujlwm ntev ntawm qhov ntsuas tam sim no

5. Thaum tshav kub kub resistant tam sim no: ith = 25inom, 3C

6. Lwm yam kev mob yuav tsum ua raws li cov qauv IEC 60137-2017 thiab GB / T 4109-2008 insulating bushings nrog AC voltage siab tshaj 1000V.

6 、 Tsheb thauj mus los thiab hoisting

1. Cov khoom thauj

1.1 cov khoom tuaj yeem thauj tau los ntawm tsheb ciav hlau, nkoj, tsheb, dav hlau thiab lwm yam kev thauj mus los. Lub tsheb ciav hlau compartment, nkoj compartment thiab tsheb compartment nqa cov khoom yuav tsum tau ceev kom huv si thiab tsis muaj kuab paug.

1.2 kev thauj khoom ntawm cov khoom yuav tsum ua raws li cov kev cai hauv kev thauj mus los, thiab cov khoom yuav tsum tau muab tso rau ruaj khov. Tsis muaj kev sib tsoo, kev sib tsoo thiab txav tau raug tso cai thaum lub sijhawm thauj mus los.

1.3 thaum lub sij hawm thauj khoom, lub inclination yuav tsum tsis txhob ntau tshaj 30 °.

1.4 Tom qab cov khoom raug xa mus rau ntawm qhov chaw nres tsheb wharf los yog tshem tawm ntawm lub davhlau ya nyob twg, cov stacking yuav tsum tsis txhob ntau tshaj peb txheej, thiab lwm yam khoom tsis tso cai rau stacked nrog lawv.

HEADING-HOM-1

High voltage parallel capacitors yog tsim rau kev sib txuas sib txuas hauv AC lub zog hluav taws xob nrog lub zog zaus (50Hz lossis 60Hz) ntawm 1kV thiab siab dua. Lawv tau siv los them nyiaj rau inductive reactive zog, txhim kho lub zog ua haujlwm, txhim kho qhov zoo ntawm qhov hluav taws xob, txo cov kab poob, thiab siv tag nrho cov txiaj ntsig ntawm kev tsim hluav taws xob thiab cov khoom siv.
