Uhlolojikelele

I-fuse kagesi ephezulu iyinto ebuthaka kakhulu esethwe ngokuzenzisa kugridi yamandla.Uma i-over-current igeleza, i-elementi ngokwayo izoshisa futhi ifake i-fuse, futhi isekethe izophulwa indima ye-arc extinguishing medium ukuvikela izintambo zamandla nezinto zikagesi.Ama-Fuse asetshenziswa kakhulu kumagridi amandla amancane ane-voltage engaphansi kuka-35 kV.

I-fuse iqukethe ishubhu ye-fuse, isistimu yokuxhumana, isivikelo seposi kanye ne-base plate (noma i-mounting plate).Ingahlukaniswa nge-fuse ekhawulelayo yamanje kanye ne-drop fuse.

Isakhiwo

I-fuse yalolu chungechunge iqukethe izivikeli ezimbili zokuthumela, isisekelo sokuxhumana, ishubhu le-fuse ne-base plate.I-post insulator ifakwe ku-base plate, isihlalo sokuxhumana sigxilwe ku-insulator yeposi, futhi ithubhu ye-fuse ibekwe esihlalweni sokuxhumana futhi ilungiswe, kodwa izigqoko zethusi emikhawulweni yomibili zilimele ku-porcelain tube, kanye ne-fuse. emgqonyeni we-fuse ukalwe ngokuhambisana nosayizi wamanje.I-fuse eyodwa noma amaningi alinyazwa kunkambo yezimbambo (isilinganiso samanje esingaphansi kuka-7.5A) noma afakwe ngokuqondile eshubhuni (isilinganiso samanje esikhulu kuno-7.5A), bese sigcwaliswa ngesihlabathi sequartz.Izembozo zethusi zisetshenziswa kuzo zombili iziphetho.Lapho i-current overload noma i-short circuit current idlula, i-fuse izoshaya ngokushesha, futhi i-arc izokhiqizwa ngesikhathi esifanayo, futhi isihlabathi se-quartz sizocisha i-arc ngokushesha.Lapho i-fuse iqhuma, ikhebula lentwasahlobo nalo lishaya futhi liphuma entwasahlobo, okubonisa ukuthi i-fuse ishaywa.Ukuze uqedele umsebenzi.

Imiyalo yokusetshenziswa

Uhlobo lwe-RN1 uhlobo lwe-quartz sand fuse yangaphakathi, ilungele:
(1) Ukuphakama akukho ngaphezu kwamamitha ayi-1000.
(2) Izinga lokushisa lendawo ezungezile alikho ngaphezu kuka +40℃, hhayi ngaphansi kuka -40℃.
Amafuse ohlobo lwe-RN1 awakwazi ukusebenza ezindaweni ezilandelayo:
(1) Izindawo zasendlini ezinomswakama olinganiselwe omkhulu kuno-95%.
(2) Kunezindawo lapho kunengozi yokushiswa kwempahla nokuqhuma.
(3) Izindawo ezinokudlidliza okukhulu, ukushwiba noma umthelela.
(4) Izindawo ezinobude obungaphezu kwamamitha ayi-2,000.
(5) Izindawo ezingcolisa umoya nezindawo ezikhethekile ezinomswakama.
(6) Izindawo ezikhethekile (njengezisetshenziswa emishinini ye-X-ray).
