Imikhiqizo Yethu

Ukucaciswa:

                Isahluko 1 -Izinhlobo Zezivikeli ze-Spool

              Isahluko 2– Ukwethulwa Kwesivikelo

Ama-insulators aphansi-voltage asetshenziselwa ukwahlukanisa kanye nezintambo ezilenga ku-low-voltage kanye ne-ultra-low voltage ac kanye nemigqa yokudlulisa i-dc.Ngakolunye uhlangothi lombhoshongo woxhumano lwezintambo ezinamandla amakhulu, kwalengiswa ama-insulators amaningi amise okwe-disc.Kwakuwukwandisa ibanga le-creepage.

                  Isahluko 3 – Isici Se-Insulator

1) inani elinguziro liphulwa ngokwalo, elilungele ukutholwa.

Isivikelo sengilazi sinesici sokuziphuka kwenani elinguziro. Uma nje uphansi noma endizeni enophephela emhlane ungabonwa, asikho isidingo sokuhlonza isigxobo ngezicucu, kunciphisa umfutho wokusebenza kwabasebenzi. emgqeni wokukhiqiza, izinga lokuziphuka lonyaka eligijimayo lingu-0.02-0.04%, elingasindisa izindleko zokugcinwa komugqa.

2) i-arc enhle kanye nokumelana nokudlidliza

Indawo entsha ye-insulator yengilazi engaphansi kokusha kombani ngesikhathi sokusebenza iseyi-vitreous ebushelelezi futhi inongqimba oluqinile lwangaphakathi lokuvikela ukucindezeleka, ngakho isagcina amandla okufaka anele namandla emishini.Kulayini we-500kv, kube nezinhlekelele ezimbalwa ezibangelwe yiqhwa. ocingweni, nokusebenza komshini nokukagesi kwesivikeli sengilazi ngemuva kokuhlolwa kokudansa kocingo.

3) ukusebenza okuhle kokuzihlanza futhi akulula ukuguga

Ngokombiko ojwayelekile womkhakha wamandla, izivikeli zengilazi akulula ukunqwabelanisa ukungcola futhi kulula ukuzihlanza.Ukusebenza kwemishini nogesi kwezivikeli zengilazi emigqeni yesifunda evamile kukalwa ngamasampula avamile, futhi izinkulungwane zedatha eziqoqiwe zibonisiwe. ukuthi ukusebenza komshini nogesi kwezivikeli zengilazi ngemva kweminyaka engu-35 yokusebenza ngokuyisisekelo kwakufana nalokho lapho ziphuma efektri, futhi kwakungekho mkhuba wokuguga.

4) umthamo omkhulu oyinhloko, ukusatshalaliswa okufanayo kwe-voltage ochungechungeni.

Ingilazi yenza i-dielectric constant engu-7-8, isivikeli sengilazi esiqinile sibe namandla amakhulu kanye nentambo yokusabalalisa i-voltage eyinhloko, inciphisa uhlangothi lwezintambo eziphansi kanye nesivikelo ku-voltage eseceleni eseduze, ukuze kuncishiswe ukuphazamiseka komsakazo, kunciphise ukulahleka kwe-corona. futhi andise impilo yesevisi ye-glass insulator, inhloso yokuqhuba umkhuba ifakazela leli phuzu

 Isahluko 4 –Isikimu sokuvikela isivikelo

Njengamanje, ukuvikela umbani kolayini ngokuyinhloko ukufaka isibambisi se-zinc oxide, kodwa ukusetshenziswa kwe-zinc oxide arrester nakho kunezinkinga ezilandelayo:
(1) ngemva kokuba isibambi se-zinc oxide sephukile noma sonakaliswe umbani, umlomo owonakele mncane futhi kunzima ukugada nokuwuthola.
(2) isibambi se-zinc oxide sidinga ukuhlolwa kanye njalo eminyakeni emi-3–5, futhi umthwalo wokuhlola mkhulu kakhulu.
(3) isibambi se-zinc oxide sidinga ukumiswa, futhi izindleko zokwakha nokunakekela ziphezulu kakhulu.
(4) uma kuqhathaniswa nesivikelo, izindleko ziphezulu, ezingahambisani nokusetshenziswa kwabantu abaningi.

Ngokuhloswe ngazo kulezi zinkinga ezingenhla, idivayisi yokuvikela umbani ye-insulator iyathuthukiswa.Ngemva kokuhlaziya, kuphetha ngokuthi isakhiwo segebe lomoya silula futhi intengo iphansi.Lolu hlobo lwegebe lomoya lisebenzisa isici sokuthi i-arc-frequency arc kulula ukuya phezulu ngaphansi kwesenzo samandla ayo kagesi kanye negesi eshisayo yamanje, futhi yenza i-arc ibe yinde, ngaleyo ndlela yenze i-arc icime.Ngakho-ke, idivayisi yokuvikela umbani we-insulator eyakhiwe nge-arc guide clamp, i-pole rod ne-negative plate yakhelwe, futhi isakhiwo esingashintshwa siyamukelwa ukuze sihlukanise i-arc guide clamp kanye nenduku yesigxobo esihle, futhi inhlanganisela yebhawodi iyamukelwa.

Uma induku ephozithivu yonakaliswa ukusha kwe-arc, induku ephozithivu ingashintshwa esikhundleni sesethi yonke, okunciphisa izindleko.
