Isishwankathelo

I-fuse yamandla ombane aphezulu yeyona nto ibuthathaka isetelwe ngokwenziwa kwigridi yamandla.Xa i-over-current flows, i-element ngokwayo iya kutshisa kunye ne-fuse, kwaye isekethe iya kwaphulwa yindima ye-arc yokucima umbane ukukhusela imigca yamandla kunye nezixhobo zombane.Iifuse zisetyenziswa ngokubanzi kwiigridi zamandla amancinci ezinomthamo ongaphantsi kwe-35 kV.

I-fuse iqukethe ityhubhu ye-fuse, i-contactive system, i-post insulator kunye ne-base plate (okanye i-mounting plate).Inokwahlulwa ibe yi-fuse enyiniweyo yangoku kunye ne-drop fuse.

Ulwakhiwo

I-fuse yolu chungechunge iqulethe i-insulators ezimbini zeposi, isiseko soqhagamshelwano, ityhubhu ye-fuse kunye ne-base plate.I-insulator yeposi ifakwe kwi-plate yesiseko, isihlalo soqhagamshelwano sigxininiswe kwi-insulator yeposi, kwaye ityhubhu ye-fuse ifakwe kwisihlalo soqhagamshelwano kwaye igxininiswe, kodwa ii-caps zobhedu kuzo zombini iziphelo zinxeba kwi-tube porcelain, kunye ne-fuse. kwi-barrel ye-fuse ilinganiswe ngokobukhulu bangoku.I-fuses enye okanye ngaphezulu inxeba kwi-ribbed core (i-rerated current engaphantsi kwe-7.5A) okanye ifakwe ngokuthe ngqo kwi-tube (i-rerated current enkulu kune-7.5A), kwaye izaliswe isanti ye-quartz.Izigqubuthelo zobhedu zisetyenziswa kuzo zombini iziphelo.Xa i-overload yangoku okanye i-short circuit current idlula, i-fuse iya kubetha ngokukhawuleza, kwaye i-arc iya kuveliswa ngexesha elifanayo, kwaye isanti ye-quartz iya kucima i-arc ngokukhawuleza.Xa i-fuse iqhuma, ikhebula lomthombo liphinde liqhume kwaye liphume entwasahlobo, libonisa ukuba i-fuse iqhume.Ukugqibezela umsebenzi.

Imiyalelo yokusetyenziswa

Uhlobo lwe-RN1 lwangaphakathi olugcwele i-quartz fuse yesanti, ilungele:
(1) Ubude abukho ngaphezu kweemitha ezili-1000.
(2) Ubushushu bendawo ejikelezileyo alikho ngaphezulu kwe +40℃, hayi ngaphantsi kwe -40℃.
Uhlobo lwe-RN1 iifusi alukwazi ukusebenza kwezi meko zilandelayo:
(1) Iindawo zangaphakathi ezinokufuma okungaphezulu kwama-95%.
(2) Kukho iindawo apho kukho ingozi yokutshiswa kwempahla nokudubula.
(3) Iindawo ezineentshukumo ezinzima, ujingi okanye impembelelo.
(4) Iindawo ezinobude obungaphezu kweemitha ezingama-2,000.
(5) Iindawo zongcoliseko lomoya kunye neendawo ezikhethekileyo ezifumileyo.
(6) Iindawo ezikhethekileyo (ezifana nezisetyenziswa kwizixhobo zeX-reyi).
