Dab tsi yog cov yam ntxwv ntawm kev faib tshuab rau high-voltage bushings?

1 Txhais:

Capacitive bushing yog ib qho khoom siv tawm uas ua rau cov kab hluav taws xob siab hauv lub tshuab hloov mus rau sab nraud ntawm lub tank roj. Nws tsis tsuas yog ua haujlwm hauv av rwb thaiv tsev rau cov hlau lead, tab sis kuj tseem ua haujlwm ruaj khov thiab yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob.

2 Kev faib tawm: Bushing tuaj yeem muab faib ua hom flushing thiab hom capacitive.

Daim ntawv cable nyob rau hauv lub tes tsho roj flushing zoo ib yam li qhov voltage equalizing phaj nyob rau hauv lub tes tsho capacitive. Lub capacitor core nyob rau hauv lub tes tsho capacitive yog ib tug series ntawm coaxial cylindrical capacitors, thaum nyob rau hauv cov roj flushing lub tes tsho, lub dielectric tas li ntawm daim ntawv insulating yog siab tshaj cov roj, uas yuav txo tau lub zog teb ntawm qhov chaw.

Lub tshuab nqus tsev twj tso kua mis tuaj yeem muab faib ua ib qho roj sib txawv thiab ntau cov roj qhov sib txawv, thaum lub capacitive hom casing tuaj yeem muab faib ua cov ntawv nplaum thiab cov ntawv roj.

3 Feature:

Thaum tus neeg nqa khoom nqa tam sim no yuav tsum dhau los ntawm lub thawv hlau los yog phab ntsa uas muaj peev xwm sib txawv, yuav tsum muaj lub tes tsho. Raws li qhov teeb meem no, bushings tuaj yeem muab faib ua transformer bushings, bushings rau cov keyboards lossis cov khoom siv ua ke, thiab phab ntsa bushings [1]. Rau qhov "plug-in" electrode kev npaj, hluav taws xob teb ntawm ntug ntawm sab nrauv electrode (xws li nruab nrab flange ntawm lub tes tsho) yog cov concentrated heev, thiab tawm feem ntau pib los ntawm no. Taw qhia rau kev ua haujlwm ntawm quartz raj?

1. Kub kub tsis kam. Lub softening point kub ntawm quartz iav yog hais txog 1730 degree, thiab nws yuav siv tau rau ib ntev lub sij hawm ntawm 1100 degree, nrog ib tug siab tshaj plaws kub ntawm 1450 degree nyob rau hauv ib tug luv luv lub sij hawm ntawm lub sij hawm,

2. Corrosion kuj. Tsuas yog hydrofluoric acid, quartz iav tsis tshua muaj tshuaj lom neeg nrog rau lwm cov tshuaj acid, thiab nws cov kua qaub tiv thaiv yog 30 npaug ntawm cov ceramics thiab 150 npaug ntawm cov hlau tsis muaj steel. Tshwj xeeb tshaj yog nyob rau hauv kub kub, nws cov tshuaj stability yog unmatched los ntawm lwm yam engineering khoom.

3. Zoo thermal stability. Lub thermal expansion coefficient ntawm quartz iav yog qhov tsawg heev thiab tuaj yeem tiv taus qhov kub thiab txias hloov. Thaum rhuab mus txog 1100 degree, quartz iav yuav tsis tawg txawm tias muab tso rau hauv chav dej kub.

4. Zoo pob tshab. Quartz iav muaj kev xa tawm zoo thoob plaws hauv tag nrho cov spectral ntau yam ntawm ultraviolet mus rau infrared, nrog lub teeb pom kev zoo tshaj 93%, tshwj xeeb tshaj yog nyob rau hauv cheeb tsam ultraviolet spectral, nrog rau qhov siab tshaj plaws transmittance ntawm tshaj 80%.

5. Kev ua haujlwm zoo ntawm hluav taws xob rwb thaiv tsev. Tus nqi tsis kam ntawm quartz iav yog 10000 npaug ntawm cov iav zoo tib yam, ua rau nws yog cov khoom siv hluav taws xob zoo heev nrog cov khoom siv hluav taws xob zoo txawm tias qhov kub thiab txias.

Vim nws lub cev thiab tshuaj lom neeg zoo heev, quartz iav yog dav siv nyob rau hauv ntau yam xws li hluav taws xob lub teeb qhov chaw, semiconductors, kho qhov muag kev sib txuas lus, tub rog kev lag luam, metallurgy, tsev cov ntaub ntawv, chemistry, machinery, hwj chim, ib puag ncig tiv thaiv, thiab lwm yam.
