Iimveliso zethu

Inkcazo:

                Isahluko soku-1 –Iintlobo zesigqugquzeli se-Spool

              Isahluko 2– Intshayelelo yesiKhuseli

Ama-insulators aphantsi-i-voltage asetyenziselwa ukugquma kunye neengcingo zokuxhoma kwi-voltage ephantsi kunye ne-ultra-low voltage ac kunye ne-dc transmission lines. Kwiminyaka yokuqala, i-insulators ephantsi kwe-voltage yayisetyenziselwa izibonda zefowuni, kwaye zaye zaphuhliswa ngokuthe ngcembe.Kwesinye isiphelo senqaba yokudibanisa i-high-voltage ye-high-voltage, i-insulators eninzi ene-disc yaxhonywa.Yayikukwandisa umgama we-creepage.

                  Isahluko sesi-3 – Uphawu lwesiKhuseli

1) ixabiso le-zero liphulwa ngokwalo, elilungele ukufumanisa.

I-insulator yeglasi inophawu lwexabiso le-zero self-breaking. Ngethuba nje emhlabeni okanye kwi-helicopter inokubonwa, akukho mfuneko yokukhwela isiqwenga sepali ngokuchongwa kweqhekeza, ukunciphisa ubuninzi bomsebenzi wabasebenzi. kumgca wemveliso, izinga lokuziqhekeza lonyaka li-0.02-0.04%, elinokugcina iindleko zokugcinwa komgca.

2) i-arc elungileyo kunye nokumelana nokungcangcazela

Umphezulu omtsha we-insulator yeglasi ephantsi kokutsha kombane ngexesha lokusebenza usemtyibilizi we-vitreous kwaye unomaleko okhuselweyo woxinzelelo lwangaphakathi, ngoko ke ugcina amandla okwaneleyo okugquma kunye namandla omatshini. Kumgca we-500kv, bekukho iintlekele ezininzi ezibangelwa ngumkhenkce. kucingo, kunye nokusebenza komatshini kunye nombane we-insulator yeglasi emva kokuba ukudansa kocingo kuhlolwe.

I-3) ukusebenza kakuhle kokuzicoca kwaye akukho lula ukuguga

Ngokwengxelo jikelele yecandelo lamandla, i-glass insulators ayilula ukuqokelela ungcoliseko kwaye kulula ukuyicoca.Ukusebenza komatshini kunye nombane we-insulators yeglasi kwimigca yengingqi eqhelekileyo yalinganiswa ngesampulu eqhelekileyo, kwaye amawaka aqokelelweyo edatha abonisiwe. ukuba ukusebenza komatshini kunye nombane we-insulators yeglasi emva kweminyaka engama-35 yokusebenza yayifana naleyo xa bephuma kumzi-mveliso, kwaye kwakungekho nto yokuguga.

4) umthamo omkhulu oyintloko, ukuhanjiswa okufanayo kombane kuthotho.

Iglasi yenza i-dielectric constant ye-7-8, i-insulator yeglasi eqinisiweyo inamandla amakhulu kunye nomtya wokuhanjiswa kwamandla ombane, ukunciphisa icala locingo olusezantsi kunye ne-insulator kwicala lombane elikufutshane, ukuze kuncitshiswe ukuphazamiseka kwerediyo, ukunciphisa ilahleko ye-corona. kunye nokwandisa ubomi benkonzo ye-insulator yeglasi, injongo yokuqhuba umsebenzi ingqina le ngongoma

 Isahluko sesi-4 –Iskim sokhuselo lwe-insulator

Okwangoku, ukukhuselwa kombane womgca ikakhulu kukufaka i-zinc oxide arrester, kodwa ukusetyenziswa kwe-zinc oxide arrester nayo inezi ngxaki zilandelayo:
(1) emva kokuba isibambi se-zinc oxide saphulwe okanye sonakaliswe ngumbane, umlomo owonakeleyo mncinci kwaye kunzima ukujikeleza nokufumana.
(2) isibambi se-zinc oxide kufuneka sivavanywe kanye emva kweminyaka emi-3 ~ 5, kwaye umsebenzi wovavanyo mkhulu kakhulu.
(3) isibambi se-zinc oxide kufuneka simiswe, kwaye iindleko zokwakha kunye nokugcinwa ziphezulu kakhulu.
(4) xa kuthelekiswa ne-insulator, ixabiso liphezulu, elingenakulungele ukusetyenziswa kobuninzi.

Ngokujoliswe kwiingxaki ezingentla, isixhobo sokukhusela umbane se-insulator siphuhlisiwe.Emva kokuhlalutya, kugqitywe ukuba isakhiwo se-gap air silula kwaye ixabiso liphantsi.Olu hlobo lwesikhewu somoya lusebenzisa uphawu lokuba i-arc-frequency arc kulula ukuya phezulu phantsi kwesenzo samandla ayo ombane kunye nerhasi eshushu yangoku, kwaye yenza i-arc ibe nde, ngaloo ndlela yenza i-arc icime.Ngoko ke, isixhobo sokukhusela umbane se-insulator esenziwe nge-arc guide clamp, intonga ye-pole kunye ne-negative plate. yenzelwe, kunye nesakhiwo esinokutshintshwa samkelwa ukwahlula i-arc guide clamp kunye nentonga yesibonda esilungileyo, kunye nendibaniselwano yebholithi yamkelwa.

Ukuba intonga elungileyo yonakaliswe kukutsha kwe-arc, intonga entle inokutshintshwa endaweni yesethi yonke, enciphisa iindleko.
