Dab tsi yog qhov ua haujlwm ntawm cov plooj (porcelain bushing ntawm lub siab - voltage caportrory?

Nyob rau hauv high - voltage fais fab tshuab, txhim kho cov khoom siv nyiaj cuam tshuam rau cov khoom siv hluav taws xob, kev siv hluav taws xob ruaj khov thiab txo lub zog poob. Thiab qhov siab - pitched, dawb}} Lub ntsej muag plooj (} bellage capacitors yog qhov tseeb ntawm cov pob hluav taws xob. Yog li, lawv ua haujlwm dab tsi raws li cas?

I. Cov tub ntxhais muaj nuj nqi ntawm bushings ceramic

1. Rwb thaiv tsev thiab kev cais tawm (qhov tseem ceeb tshaj plaws thiab cov tub ntxhais ua haujlwm)

Sab hauv rwb thaiv tsev: cov tub ntxhais ntawm lub capacitor yog tsim ntawm ntau cov khoom txuas nrog hauv cov koob thiab sib piv. Lub teb chaws ua hauj lwm lub zog yog tsis tshua muaj siab. Cov xov hlau coj txuas rau cov tub ntxhais muaj qhov sib txawv ntawm cov sib txawv (voltage) nrog cov hlau casing ntawm lub capacitor ntawm lub capacitor ntawm tus kheej. Cov plooj (veneers) bushing ua haujlwm li qhov hluav taws xob rau cov hlau txhuas, thiab sab hauv kom tiv thaiv cov hlau ua kom muaj kev tshem tawm.

Cov rwb thaiv tsev sab nraud: thaum ua haujlwm sab nraud, capacitors yuav ntsib cov chaw ib puag ncig xws li noo noo, hws, thiab av. Cov plooj (veneers) bushing ua tau zoo thiab kev tiv thaiv kom haum rau ntawm lub siab.

2. Kev pab txhawb zog txhua yam thiab kev txhim kho

Lub plooj (veneers) bushing nws tus kheej tau muaj kev siv zog (tsis kam mus rau compression thiab khoov). Nws muab kev txhawb nqa ruaj khov rau ob peb hnyav tooj liab tuav lossis cable} Qhov hnyav thiab kev txhim kho hluav taws xob lossis kev sib cav sab nraud, thiab lwm yam, yog li tsis txhob ua txhaum.

3. Kev tiv thaiv luas

Cov neeg sawv cev ntawm capacitorors (xws li insulating roj, ib puag ncig cov roj av, thiab lwm yam. Lawv yuav tsum tau nruj me ntsis kom tiv thaiv kom tsis txhob to feakage thiab noo noo kev nqus. Cov kev sib txuas ntawm cov plooj (paptain

Ii. Vim li cas thiaj xaiv "Porcelain" raws li cov khoom siv?

1. Kev tiv thaiv hluav taws xob siab heev: Zoo heev withstand voltage kev ua tau zoo, muaj peev xwm ntawm cov hluav taws xob siab heev thiab impulse voltage.

2. Zoo heev mechanical zog: tiv taus compression thiab khoov, muaj peev xwm nrog nrog nrog hluav taws xob loj thiab hluav taws xob siab.

3. Cov huab cua zoo heev: anti {- {{{2} {{2} {{2} {{2} {{2} {

4. Zoo heev thermal stability: Qhov thermal nthuav kev coefficient yog tsawg, ua rau nws tsis tshua tawg vim yog kev hloov pauv kub tam sim no, thiab cov thermal conductivity yog nruab nrab.

5. Lub zog anti {{- Cov kab mob muaj kuab paug: Cov nplaim yog du thiab tsis nthuav plua plav yooj yim. Txawm hais tias muaj av, ntau lub kaus mom Umbrella nyob rau hauv nws cov qauv yuav ua tau zoo nce kev deb thiab tiv thaiv grashover.
