Zvigadzirwa zvedu

Tsanangudzo:

                Chitsauko 1 -Mhando dzeSpool insulator

              Chitsauko 2– Nhanganyaya yeInsulator

Low-voltage insulators anoshandiswa pakuisa uye kurembera waya mu low-voltage uye ultra-low voltage ac uye dc transmission lines.Mumakore ekutanga, low-voltage insulators ainyanya kushandiswa pamatanda efoni, uye akagadzirwa zvishoma nezvishoma.Pane imwe magumo eiyo high-voltage waya yekubatanidza tower, akawanda ma disc-shaped insulators akaturikwa.Kwaiva kuwedzera creepage distance.

                  Chitsauko 3 – Feature Of Insulator

1) iyo zero kukosha yakaputsika pachayo, iyo iri nyore kuti ionekwe.

Girazi insulator ine hunhu hwe zero value self-breaking.Kureba pasi kana muherikoputa ichigona kucherechedzwa, hapana chikonzero chekuisa danda chidimbu nekuonekwa kwechidimbu, kuderedza simba rekushanda kwevashandi.Kune zvigadzirwa zvakaunzwa. mumutsara wekugadzira, iyo yegore inomhanya yekuzvityora mwero ndeye 0.02-0.04%, iyo inogona kuchengetedza mutengo wekugadzirisa wemutsara.

2) yakanaka arc uye vibration kuramba

Iyo nyowani yegirazi insulator inopiswa nemheni panguva yekushanda ichiri yakatsetseka vitreous uye ine yakaomeswa mukati mekudzivirira kushushikana kwemukati, saka ichiri kuchengetedza yakakwana yekudzivirira simba uye simba remagetsi.Mumutsara we500kv, pakanga paine njodzi dzakawanda dzakakonzerwa nechando. pawaya, uye mashandiro emuchina uye emagetsi egirazi insulator mushure mekutamba kwewaya kwakaedzwa.

3) yakanaka yekuzvichenesa kuita uye kwete nyore kuchembera

Zvinoenderana neshumo yakajairika yechikamu chemagetsi, magirazi insulators haasi nyore kuunganidza kusvibiswa uye ari nyore kuchenesa. Iyo mechanical uye magetsi emagetsi emagetsi egirazi insulators pamitsetse yedunhu yakayerwa neyakajairwa sampling, uye yakaunganidzwa zviuru zve data zvakaratidzwa. kuti mashandiro emagetsi uye emagetsi egirazi insulators mushure memakore makumi matatu nemashanu ekushanda aive akafanana neaya pavakabva mufekitori, uye pakanga pasina chiitiko chekuchembera.

4) hombe huru kugona, yunifomu kugovera voltage munhevedzano.

Girazi rinoita kuti dielectric irambe iri 7-8, yakaomeswa girazi insulator ine hombe capacitance uye tambo huru yunifomu voltage kugovera, kuderedza pasi waya waya uye insulator padivi pedivi voltage, kuitira kuderedza redhiyo kupindira, kuderedza kurasikirwa kwekorona. uye kurebesa hupenyu hwebasa regirazi insulator, chinangwa chekumhanya kudzidzira chinoratidza iyi pfungwa

 Chitsauko 4 -Chirongwa chekudzivirira chidziviriro

Parizvino, kudzivirira mheni kwemutsara kunonyanya kuisa zinc oxide arrester, asi kushandiswa kwezinc oxide arrester kunewo matambudziko anotevera:
(1) mushure mekunge zinc oxide arrester yaputsika kana kukuvadzwa nemheni, muromo wakakuvadzwa idiki uye zvakaoma kutenderera uye kuwana.
(2) zinc oxide arrester inoda kuongororwa kamwe chete pamakore matatu ~ 5, uye basa rekuedza rakakurisa.
(3) zinc oxide inosunga inoda kudzikiswa, uye mutengo wekuvaka nekugadzirisa wakakwirisa.
(4) kana ichienzaniswa neinodzimisa, mutengo wakakwira, izvo zvisingakodzeri kushandiswa kwevazhinji.

Tichifunga nezvematambudziko ari pamusoro, mudziyo wekudzivirira mheni we insulator unogadzirwa.Mushure mekuongorora, zvinogumiswa kuti iyo mhepo gap chimiro chiri nyore uye mutengo wakaderera.Iri rudzi rwemhepo gap rinoshandisa chimiro chekuti simba-frequency arc. iri nyore kukwira kumusoro pasi pekuita kwesimba rayo remagetsi uye gasi rinopisa, uye rinoita kuti arc irebe, zvichiita kuti arc idzime.Saka, insulator mheni yekudzivirira mudziyo inoumbwa nearc guide clamp, positive pole rod uye negative plate ndiyo. yakagadzirwa, uye chimiro chinotsiviwa chinogamuchirwa kupatsanura arc gwara rinosungirira uye yakanaka danda tsvimbo, uye bhaudhi musanganiswa unogamuchirwa.

Kana iyo tsvimbo yakanaka yakakuvadzwa nekupisa kwearc, tsvimbo yakanaka inogona kuchinjwa panzvimbo yeseti yose, iyo inoderedza mari.
