Izinhlobo zokuhlolwa kokukhishwa kwengxenye kanye nezindawo ezifanele

Kungase kube nokukhishwa okuyingxenye endaweni yokuhlukanisa impahla yamandla ezintanjeni ezisanda kwenziwa noma amakhebuli ekusebenzeni kwesikhathi eside.Ukuze kutholwe lokho kukhubazeka nokuwohloka kwe-insulation ngokushesha ngangokunokwenzeka, ukuhlolwa kokukhipha ingxenye ezintamboni kungavimbela futhi kutholwe izinkinga futhi kumise ukulahlekelwa ngesikhathi.gwema ukulahlekelwa okwengeziwe.

Idivayisi yokuhlola yochungechunge lwe-GDYT engakhishelwa ngaphandle

I-HV Hipot GDYT yochungechunge lwedivayisi yokuhlola yokukhipha ingxenye

 
Izinhlobo zokuhlolwa kokukhishwa kwengxenye kanye nezindawo ezifanele?
Isetshenziselwa kakhulu ukubona ukukhishwa okungaphelele kwezintambo ezinamandla kagesi angu-110kV nangaphezulu, kusetshenziswa amathuluzi ukuqoqa amasignali ebhokisini lentambo eliphansi, nokukhetha izinhlobo ezihlukene zokuhlola ngokuya ngendawo yendawo kanye nezidingo, ezingahlukaniswa ikakhulukazi zibe izinhlobo ezi-4. :
① Ukumelana nokuhlolwa kokukhipha ingxenye ye-voltage.Sebenzisana nemishini yokuhlola i-voltage ephezulu eqinile njengokuguqulwa kwemvamisa noma i-resonance yochungechunge, futhi wenze isilinganiso sokukhipha ingxenye ngesikhathi sokuqedwa kwekhebula noma ukuhlolwa okuvamile.
② Ukuhlolwa kokutholwa bukhoma.Sebenzisa izinzwa zokulinganisa ezifana ne-HFCT, ingalo ye-high-frequency capacitive, i-foil membrane electrode, njll. ukuze ulinganise ukuchithwa kwengxenye eshajikiwe kwekhebula.
③ Ukuqapha kwe-PD okuku-inthanethi.Okokusebenza kokutholwa kufakwe kusayithi lokuhlola ukuze kuqashwe isignali yokukhishwa kwengxenye yesikhathi sangempela.
④ Ukunakekelwa okujulile.Idivayisi ingafakwa esizeni ukuze igade amathrendi ekhebula le-PD ku-inthanethi ngokunakekelwa okukhulu kwesikhathi esifushane noma eside.
