Porcelain thiab polymer insulators yog ob qho tib si siv hauv cov tshuab hluav taws xob los muab kev rwb thaiv tsev thiab kev txhawb nqa rau cov hluav taws xob siv hluav taws xob, cov chaw siv hluav taws xob, thiab lwm yam khoom siv hluav taws xob. Txawm li cas los xij, lawv txawv heev hauv lawv cov khoom siv, kev tsim kho, kev ua tau zoo, thiab kev siv. Ntawm no yog qhov sib txawv ntawm qhov sib txawv ntawm cov plooj (porcelain) thiab polymer insulators:
1. Khoom siv:
- Porcelain Insulators: Porcelain insulators feem ntau yog tsim los ntawm cov khoom siv ceramic xws li av nplaum, feldspar, thiab alumina. Cov ntaub ntawv no raug rho tawm haujlwm ntawm qhov kub thiab txias los tsim cov khoom siv insulating ntom ntom thiab ruaj khov.
- Cov hluav taws xob hluav taws xob hluav taws xob muaj zog: Polymer insulators, tseem hu ua cov khoom siv hluav taws xob, yog tsim los ntawm cov khoom siv hluavtaws xws li roj hmab silicone lossis ethylene propylene diene monomer (EPDM) roj hmab rau lub tsev (cov vaj tsev sab nrauv) thiab cov khoom siv tseem ceeb xws li fiberglass lossis aramid. fiber ntau.
2. Kev tsim kho:
- Porcelain Insulators: Porcelain insulators feem ntau yog muaj ntau lub plooj (porcelain discs) stacked ua ke nrog cov khoom siv hlau xws li lub kaus mom hlau thiab tus pins. Cov discs no feem ntau yog cemented ua ke los tsim ib qho khoom siv.
- Polymer Insulators: Polymer insulators muaj ib qho kev tsim kho nrog cov vov tsev thiab cov tub ntxhais pas nrig sib xyaw ua ke hauv chav tsev monolithic. Hlau fittings los yog kawg fittings yog feem ntau txuas mus rau qhov kawg ntawm lub insulator kom yooj yim installation thiab kev twb kev txuas mus rau conductors los yog txhawb cov qauv.
3. Nyhav:
- Porcelain Insulators: Porcelain insulators kuj hnyav vim qhov ntom ntom ntawm cov ntaub ntawv ceramic. Lawv zoo li muaj qhov hnyav dua piv rau polymer insulators.
- Composite kab post insulator: Polymer insulators yog lub teeb yuag vim siv cov khoom siv hluavtaws. Lawv feem ntau sib dua li cov plooj (porcelain insulators), ua rau lawv yooj yim rau kev tswj thiab nruab.
4. Lub zog:
- Porcelain Insulators: Porcelain insulators muaj lub zog txhua yam thiab tiv taus rau lub cev puas tsuaj xws li kev cuam tshuam lossis kev co. Txawm li cas los xij, lawv tuaj yeem nkig thiab ua rau tawg hauv qee yam mob.
- Polymer Insulators: Polymer insulators muaj lub zog zoo heev thiab tiv taus kev puas tsuaj los ntawm kev cuam tshuam thiab kev vibration piv rau cov porcelain insulators. Lawv kuj hloov tau yooj yim dua, txo qhov kev pheej hmoo ntawm kev tawg thaum tuav lossis hauv cov huab cua.
5. Kev ua pa phem:
- Porcelain Insulators: Porcelain insulators muaj qhov cuam tshuam rau cov pa phem flashover, qhov chaw muaj kab mob xws li plua plav, ntsev, lossis cov pa phem tso rau ntawm qhov chaw, ua rau hluav taws xob arcing thiab rwb thaiv tsev tsis ua haujlwm.
- Polymer Insulators: cov kab hluav taws xob hluav taws xob muaj cov pa phem ua haujlwm zoo vim yog cov khoom siv hluav taws xob ntawm cov roj hmab silicone, uas tshem tawm cov dej thiab cov kab mob. Qhov no ua rau lawv tsis tshua muaj kuab paug flashover thiab zoo tagnrho rau siv nyob rau hauv cov pa phem los yog ntug hiav txwv ib puag ncig.
6. Kev txhim kho thiab tu:
- Porcelain Insulators: Txhim kho porcelain insulators yuav tsum tau ceev faj tuav vim lawv qhov hnyav thiab tsis muaj zog. Kev tu yuav koom nrog kev tu tsis tu ncua kom tshem tawm cov kab mob thiab tshuaj xyuas cov kab nrib pleb lossis kev puas tsuaj.
- Polymer Insulators: Polymer insulators yooj yim dua los tuav thiab nruab vim lawv lub teeb yuag thiab ib qho kev tsim kho. Lawv feem ntau xav tau kev saib xyuas tsawg dua vim tias lawv tsis tshua muaj kev puas tsuaj los ntawm ib puag ncig thiab muaj kev ua qias tuaj zoo dua.
Thaum ob qho tib si porcelain thiab polymer insulators ua haujlwm zoo ib yam ntawm kev muab hluav taws xob rwb thaiv tsev, polymer insulators muaj qhov zoo ntawm qhov hnyav, kev ua qias tuaj, thiab yooj yim ntawm kev tuav thiab teeb tsa. Txawm li cas los xij, kev xaiv ntawm porcelain thiab polymer insulators nyob ntawm ntau yam xws li daim ntawv thov tshwj xeeb, ib puag ncig, thiab kev txwv nyiaj txiag.
