Isiphazamisi seVacuum Ku-40.5kV TD-40.5/2500-31.5(163)

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Incazelo emfushane yomkhiqizo:

Isiphazamisi se-vacuum, esaziwa nangokuthi i-vacuum switch tube, siyingxenye eyinhloko yeswishi yamandla kagesi aphezulu aphakathi nendawo.Isetshenziswa kakhulu ohlelweni lokulawulwa kokudluliswa kukagesi kanye nokusabalalisa, futhi isetshenziswa nasezinhlelweni zokusabalalisa zensimbi, imayini, i-petroleum, amakhemikhali, ujantshi, ukusakaza, ukuxhumana kanye nokushisisa imvamisa ephezulu yezimboni.Isiphazamisi se-vacuum sinezici zokonga amandla, ukonga izinto ezibonakalayo, ukuvimbela umlilo, ukuvikela ukuqhuma, umthamo omncane, impilo ende, izindleko zokulungisa eziphansi, ukusebenza okuthembekile futhi akukho kungcola.Ukushintsha komthwalo kusetshenziselwa ikakhulukazi abasebenzisi be-terminal begridi yamandla.Lapho i-voltage yefrikhwensi yamandla iseduze noziro, futhi ngesikhathi esifanayo, ngenxa yokwanda kwebanga lokuvula othintana naye, I-plasma ye-vacuum arc ihlakazeka ngokushesha nxazonke.Ngemuva kokuthi i-arc current idlule ku-zero, i-medium egebeni lokuxhumana ishintsha ngokushesha ukusuka ku-conductor ukuya ku-insulator, ngakho-ke i-current iyanqanyulwa.Ngenxa yesakhiwo esikhethekile sothintana naye, igebe lokuxhumana lizokhiqiza insimu yamagnetic longitudinal ngesikhathi se-arcing.Le nkundla kazibuthe ingenza i-arc isatshalaliswe ngokulinganayo endaweni yokuxhumana, igcine i-voltage ephansi ye-arc, futhi yenze igumbi lokucisha i-arc le-vacuum libe nesivinini sokuthola kabusha samandla e-post arc dielectric, okuholela emandleni amancane e-arc kanye nesilinganiso esincane sokugqwala.Ngale ndlela, umthamo wamanje ophazamisayo nempilo yesevisi yesiphazamisi se-vacuum iyathuthukiswa.

FAQ

Q:Ingabe imboni yakho ingakhiqiza ngokwezidingo zekhasimende?
A: Yebo, imikhiqizo oyifisayo iyamukeleka.Sicela usithumele imininingwane nge-E-mail noma iWhatsapp.

Q:Liyini izinga lakho lephakheji?
A: Ngokuvamile sisebenzisa igwebu elivamile nebhokisi ukuze sihlanganise.Uma unezicelo ezikhethekile, singakwazi futhi ngokwezidingo zakho.

Q:Singakwazi ukuvakashela inkampani yakho?
A: Yebo, ngokuqinisekile, wamukelekile ukuvakashela inkampani yethu.

Q:Ingabe unayo ikhathalogi?Ungakwazi ukungithumelela ikhathalogi yakho?
A:Yebo, sinawo amakhathalogi.Sicela usithinte, singakuthumelela ikhathalogi yomkhiqizo ku-inthanethi namafayela e-PDF.
