Mwachidule

Fuse yokwera kwambiri ndiye chinthu chofooka kwambiri chomwe chimayikidwa mu gridi yamagetsi.Pamene over-current ikuyenda, chinthucho chimatenthetsa ndi kusakaniza, ndipo dera lidzasweka ndi ntchito ya arc kuzimitsa sing'anga kuteteza zingwe zamagetsi ndi zida zamagetsi.Ma fuse amagwiritsidwa ntchito kwambiri m'magulu ang'onoang'ono amagetsi okhala ndi voteji pansi pa 35 kV.

Fuseyi imakhala ndi fuse chubu, contact conductive system, post insulator ndi base plate (kapena mounting plate).Itha kugawidwa m'mafusi ochepera apano ndi madontho.

Kapangidwe

Fuse ya mndandandawu imakhala ndi ma insulators awiri, cholumikizira, fuse chubu ndi mbale yoyambira.Insulator ya positi imayikidwa pa mbale yoyambira, mpando wolumikizana umayikidwa pa positi insulator, ndipo fuse chubu imayikidwa pampando wolumikizana ndikukhazikika, koma zipewa zamkuwa pamapeto onse awiri zimavulazidwa pa chubu cha porcelain, ndi fusesi. mu mbiya ya fuseyi imavoteredwa malinga ndi kukula kwapano.Fuse imodzi kapena zingapo zimaphwanyidwa pa nthiti zapakati (zovotera panopa zosakwana 7.5A) kapena zimayikidwa mwachindunji mu chubu (chiwerengero chamakono choposa 7.5A), ndiyeno chimadzazidwa ndi mchenga wa quartz.Zophimba zamkuwa zimagwiritsidwa ntchito kumbali zonse ziwiri.Pamene mphamvu yowonjezera yamakono kapena yaifupi ikudutsa, fusejiyo idzawombera nthawi yomweyo, ndipo arc idzapangidwa nthawi yomweyo, ndipo mchenga wa quartz udzazimitsa arc nthawi yomweyo.Fuseyo ikawomba, chingwe cha kasupe chimawombanso ndikutuluka mu kasupe, kusonyeza kuti fuseyo imawombedwa.Kuti amalize ntchitoyi.

Malangizo ogwiritsira ntchito

Mtundu wa RN1 wamkati wodzaza mchenga wa quartz, woyenera:
(1) Kutalika sikuposa 1000 metres.
(2) Kutentha kwa sing'anga yozungulira sipamwamba kuposa +40 ℃, osati kutsika kuposa -40 ℃.
Ma fuse amtundu wa RN1 sangagwire ntchito m'malo otsatirawa:
(1) Malo amkati okhala ndi chinyezi chambiri kuposa 95%.
(2) Pali malo amene pali ngozi yopsereza katundu ndi kuphulika.
(3) Malo okhala ndi kugwedezeka kwakukulu, kugwedezeka kapena kukhudza.
(4) Madera okhala ndi mtunda wopitilira 2,000 metres.
(5) Malo oyipitsa mpweya ndi malo apadera achinyezi.
(6) Malo apadera (monga omwe amagwiritsidwa ntchito pazida za X-ray).
