UKUKHETHA KWESHINTSHI LOMTHWALO WE-VOLTAGE HIGH

Okokuqala, kubalulekile ukuqonda indawo yokusetshenziswa. Iswishi yomthwalo we-high-voltage iyithuluzi likagesi elinomsebenzi walo phakathi kwe-high-voltage circuit breaker kanye ne-high-voltage isolation switch. Iswishi yomthwalo we-high-voltage ivame ukusetshenziswa ochungechungeni lwe-high-voltage fuse; isetshenziselwa ukulawula i-power transformer. Iswishi yomthwalo we-high-voltage inedivayisi elula yokucisha i-arc, ngoba ingavula futhi ivale i-load current ethile kanye ne-overload current. Kodwa-ke, ayikwazi ukuxhuma i-short-circuit current, ngakho-ke ngokuvamile isetshenziswa ochungechungeni lwe-high-voltage fuse yokuvikela i-short-circuit.

Amanothi Okukhetha:

1. Isilinganiso samanje, shiya umkhawulo ongaba ngu-30%

2. I-voltage ekalwe: efanayo noma ephakeme kune-voltage yangempela

3. Ugesi ophukayo kufanele uhambisane nezidingo zomklamo

4. Imvamisa yokusebenza kufanele idlule izidingo zomklamo cishe ngo-10%

5. Umthamo uhambisana nezimo zangempela zesayithi

6. Ukuthembeka, ukuphepha kuqala

Uyini umsebenzi oyinhloko weswishi yomthwalo we-voltage ephezulu?

Iswishi yomthwalo we-high-voltage iyithuluzi likagesi elikhethekile kusekethe ye-high-voltage esetshenziselwa ukuxhuma noma ukuxhuma i-load current ngaphansi kwe-voltage elinganisiwe. Nakuba inedivayisi yokucisha i-arc, ikhono layo lokucisha i-arc libuthakathaka, futhi linganqamula futhi lixhume i-load current evamile kuphela, kodwa alikwazi ukusetshenziselwa ukunqamula i-short-circuit. Ngaphansi kwezimo ezijwayelekile, iswishi yomthwalo isetshenziswa kanye ne-fuse ye-high-voltage, futhi i-fuse idlala indima yokuvikela i-short-circuit.
