I-P-70 Porcelain Post Insulator

Isithombe esifakiwe se-P-70 Porcelain Post Insulator

Incazelo emfushane:

I-post insulator iyisilawuli esikhethekile sokwahlukanisa esingadlala indima ebalulekile kulayini wokudlulisa ongaphezulu.Eminyakeni yokuqala, ama-insulators ezinsika ayesetshenziselwa kakhulu izigxobo zocingo, ezathuthukiswa kancane kancane ukuze zilengise ama-insulators amaningi anjenge-suspension ekupheleni kombhoshongo woxhumano lwezintambo eziphezulu ukuze kwandiswe ibanga le-creepage.Ngokuvamile zenziwe nge-silica gel noma i-ceramic, futhi zibizwa ngokuthi ama-insulators.
Isivikelo senduku kalayini we-voltage ephezulu sisetshenziswa njenge-insulation kanye ne-conductor esekelayo kumzila wokudlulisa nokusabalalisa amandla kagesi aphezulu.Umkhiqizo uyisakhiwo esingaqhekeki futhi unezinzuzo zamandla aphezulu emishini, ukusebenza okuqinile kokufakwa kwe-insulation kanye nokumelana okuhle nokungcola.I-insulator inezinzuzo zokusebenza okuphephile nokuthembekile, ukugcinwa okulula, impilo ende yesevisi kanye nezindleko zomugqa ophansi.

Incazelo Yomkhiqizo

I-post insulator iyisilawuli esikhethekile sokwahlukanisa esingadlala indima ebalulekile kulayini wokudlulisa ongaphezulu.Eminyakeni yokuqala, ama-insulators ezinsika ayesetshenziselwa kakhulu izigxobo zocingo, ezathuthukiswa kancane kancane ukuze zilengise ama-insulators amaningi anjenge-suspension ekupheleni kombhoshongo woxhumano lwezintambo eziphezulu ukuze kwandiswe ibanga le-creepage.Ngokuvamile zenziwe nge-silica gel noma i-ceramic, futhi zibizwa ngokuthi ama-insulators.
I-insulator emigqeni yokudlulisa phezulu enendima ezimbili eziyisisekelo, okuyizintambo zokusekela nokuvimbela imuva lamanje, le misebenzi emibili kufanele iqinisekiswe, isivikeli akufanele sikhiqize ushintsho ngenxa yezimo zemvelo kanye nezimo zomthwalo kagesi ziholela ekuqhekekeni nasekuhlulekeni kwe-flashover, noma isivikelo sizolahleka. , izolimaza wonke umugqa wokusetshenziswa nempilo yokusebenza.

Ukusebenza

1. Izivikeli zeposi zihambisana nezinhlinzeko ze-GB8287.1 “Izimo Zobuchwepheshe Zezici Ezifaka Ubumba Ezingama-Voltage Eziphezulu” kanye ne-GB12744 “Izikhiqizi Ezimelana Nokungcola Kwebha yangaphandle Ye-Porcelain”.Iphinde ihambisane nezidingo zezinga lamazwe ngamazwe le-IEC168, Ukuhlolwa Kwezinsimbi Zobumba noma zengilazi zokusebenzisa ama-Post Insulators ukuze zisetshenziswe ngaphakathi nangaphandle ezinhlelweni ezinama-Voltages angaphezu kuka-1000 V, kanye nokushicilelwa kwe-IEC 815, Imihlahlandlela yokukhethwa Kwezivikeli ngaphansi kwezimo zokungcola.

I-2, amandla emishini ye-insulator aphezulu, ukuhlakazeka okuncane, ukusebenza okuphephile nokuthembekile.

3, insulator izinga lokushisa eliphansi ukusebenza mechanical muhle.
Ukuze kuhlolwe izakhiwo zemishini ye-cryogenic yomkhiqizo, isivikeli se-zSW1-110/4 sahlolwa elabhorethri ye-cryogenic ye-Institute of Water Resources, i-Songliao Water Conservancy Commission, ukulingisa ukuguqulwa kwezinga lokushisa langaphandle ebusika.Ngemuva kwemijikelezo yokushisa eminingana, amakristalu okuhlola ahlolwe ukwehluleka ukugoba ezingeni lokushisa eliphansi.Imiphumela yokuhlolwa ikhombisa ukuthi amandla okuhluleka ukugoba ama-insulators ku--40℃ akanalo ushintsho olubalulekile uma kuqhathaniswa nalawo ezingeni lokushisa legumbi.

4. Ukuphazamiseka komsakazo okuphansi.
Isivikelo esinamandla kagesi esilinganiselwe esingu-550kV singakwazi ukukhiqiza ukuphazamiseka komsakazo okungengaphezu kuka-500μV izikhathi ezingu-1.1 ubukhulu bevoltheji yesigaba sokusebenza, akukho corona ebonakalayo ngobusuku obucwathile, kanye nomthamo we-corona obonakalayo ofika ku-450kV.
