Imyiteguro y'umutekano:
Mu gukuramo fuse yo mu bwoko bwa drop type, umukozi agomba gukoresha inkoni yo gukingira ifite urwego rukwiye rw'amashanyarazi kandi agatsinda ikizamini, yambara inkweto zo gukingira, uturindantoki two gukingira, umupfundikizo n'amadarubindi yo gukingira, cyangwa agahagarara ku rukuta rw'imbaho rwumye, kandi agakurikiranwa kugira ngo arinde umutekano we bwite.
Inyandiko:
Iyo umukoresha atangije cyangwa arangije gukurura cyangwa gufunga fuse imanuka, nta ngaruka zizaba zihari. Ingaruka zizangiza fuse, nko gukurura no guca icyuma gikingira, gukurura umunwa w'igitambaro, gukurura no kumena impeta y'igikorwa, nibindi. Abakozi ntibagomba gukoresha imbaraga nyinshi mu gihe cy'ikoreshwa rya fuse yo mu bwoko bwa dose, kugira ngo hirindwe kwangirika kwa fuse, kandi gucikamo no gufunga bigomba kuba biri aho.
Imbaraga z'imikorere ya fuse zigenda buhoro (gutangira) - vuba (iyo aho ihuza riri hafi y'aho ihuza) - buhoro (iyo aho ihuza riri hafi yo gufunga). Uburyo bwo gukurura fuse bugenda buhoro (gutangira) - vuba (iyo aho ihuza riri hafi y'aho ihuza) - buhoro (iyo aho ihuza riri hafi yo gukurura). Kwihuta ni ukurinda amashanyarazi guhagarara no gutwika aho ihuza biterwa n'umurambararo, gutinda ni ukubuza imbaraga z'impanuka gukora, bigatera kwangirika kwa mashini kuri fuse.
Ohereza itegeko
Uburyo bwo guhagarika gutanga umuriro w’amashanyarazi wa transformateur ikwirakwiza umuriro bukurikira: Mu bihe bisanzwe, hagomba kubanza gukururwa switch ifite voltage nke ku ruhande rw’umutwaro, hanyuma hagakururwa fize ifite voltage nyinshi ku ruhande rw’umutwaro.
Mu gihe cy’amashanyarazi menshi, hakurikijwe uko umuriro uhagaze, bishobora gukumira transformer isubira inyuma, mu gihe habayeho ikibazo, uburinzi bushobora kwanga kugenda, bwongere igihe cyo gukuraho amakosa, bigatuma impanuka yaguka. Gukoresha uburyo bwo kohereza umuriro intambwe ku yindi uhereye ku ruhande rw’amashanyarazi bishobora kugabanya umuvuduko utangira ingaruka (umuzigo), kugabanya ihindagurika ry’amashanyarazi, no kwemeza ko ibikoresho bikora neza. Mu gihe habayeho ikibazo, bishobora guhita bigwa cyangwa bigahagarika igikorwa, byoroshye kugenzura, gusuzuma no gukemura ikibazo hakurikijwe urugero rw’amashanyarazi. Mu gihe habayeho ikibazo, banza uhagarike uruhande rw’umuzigo. Mu gihe habayeho ikibazo cy’amashanyarazi intambwe ku yindi uhereye ku muvuduko muke ujya ku muvuduko mwinshi, switch ishobora kwirinda gukata umuvuduko munini w’amashanyarazi no kugabanya ubwinshi n’inshuro by’imikorere hejuru y’amashanyarazi.
Mu gikorwa, gerageza kwirinda gukurura no kujugunya fusi zifite umutwaro. Iyo bigaragaye ko fusi zifite umutwaro zahuye nabi mu gihe cy'igikorwa, nubwo fusi zahuye nabi cyangwa se arc ibaye, ntibyemewe kongera gufungura fusi. Iyo fusi ifite umutwaro idahuye neza ibaye, iyo aho ihurira hagiye hasigara gusa aho ihurira, hazabaho arc. Muri iki gihe, igomba gufungwa ako kanya kugira ngo ikurweho arc kandi wirinde kwaguka kw'impanuka. Ariko, niba fusi zose zafunguwe, ntibyemewe kongera gufunga fusi zakuruwe nabi. Ku bahinduramajwi bafite ubushobozi bwa kva 200 cyangwa munsi yayo, fusi ziri ku ruhande rw'amashanyarazi menshi zemerewe gutandukana no guhuza umuvuduko w'umutwaro.
Urukurikirane rw'imikorere
Urukurikirane rw'imikorere y'ibice bitatu bya fuse igabanya umuriro mwinshi.
Ingufu zikoreshwa mu kunanirwa, zigomba kubanza gukurura igice cyo hagati, hanyuma zigakurura impande zombi z'igice.
Impamvu nyamukuru yo gukurura igice cyo hagati mbere ni ukureba ko umuyoboro w'amashanyarazi iyo igice cyo hagati giciwe ari muto ugereranije n'igice cyo ku ruhande (igice cy'umutwaro w'uruziga gitwarwa n'ibice bibiri), bityo umuyoboro w'amashanyarazi uba muto, kandi nta ngaruka ku mpande zombi z'igice. Iyo fuse y'ubwoko bwa kabiri (igice cyo ku ruhande) ikoreshejwe, umuyoboro w'amashanyarazi uba munini, mu gihe igice cyo hagati cyakuwemo, kandi izindi fuse ebyiri zo mu bwoko bwa amashanyarazi ziba kure cyane, ibyo bishobora gukumira umuyoboro mugufi hagati y'ibice biterwa n'umuyoboro muremure. Iyo hari umuyaga mwinshi, tugomba kubanza gukurura igice cyo hagati, hanyuma tugakurura igice cyo ku ruhande, hanyuma tugakurura igice cyo ku ruhande mu buryo bw'ibura ry'amashanyarazi.
Mu kohereza amashanyarazi, impande ebyiri z'icyiciro cya mbere, nyuma y'icyiciro cyo hagati.
Iyo ingufu zoherejwe, igice cya mbere cy'umuyaga, hanyuma kigasubira mu cyiciro cya phoenix, hanyuma igice cyo hagati, kugira ngo hirindwe ko umuyaga ugenda ugabanuka bitewe n'umurambararo w'umuyaga.
Inyandiko yo gushyiraho
Amabwiriza yo kwitondera gushyiraho firize y'amashanyarazi amanuka afite ingufu nyinshi
1, ishyirwaho rigomba kuba ari ugushonga kw'umusatsi (gushonga ku rugero rwa 24.5N), bitabaye ibyo byoroshye gutera ubushyuhe bw'umusatsi.
2, icyuma gishyirwa ku kuboko (umuyoboro) kigomba kuba gikomeye kandi cyizewe, ntigishobora kugira ikintu icyo ari cyo cyose kinyeganyega cyangwa kinyeganyega.
3. Umuyoboro ushongesha ugomba kugira inguni ya 25°±2°, kugira ngo umuyoboro ushongesha ushobore kugwa vuba bitewe n'uburemere bwawo iyo ushongesha uvanze.
4. Fuse igomba gushyirwa ku kuboko kwambukiranya (umuyoboro) intera ihagaze itari munsi ya metero 4 uvuye ku butaka. Iyo ishyizwe hejuru ya transformateur ikwirakwizwa, igomba kugumana intera itambitse irenga metero 0.5 uvuye ku mupaka wo hanze wa transformateur ikwirakwizwa, mu gihe habayeho izindi mpanuka zatewe n'imiyoboro yashongeshejwe igwa.
5. Uburebure bw'umuyoboro ushongesha bugomba guhindurwa neza. Ni ngombwa ko ururimi rw'umunwa w'igitambaro rushobora gupfunyika hejuru ya bibiri bya gatatu by'uburebure bw'aho gifatanye nyuma yo gufunga, kugira ngo hirindwe ko cyagwa ubwacyo mu gihe cy'ikorwa.
6. Ishonga ikoreshwa igomba kuba ari yo isanzwe ikoreshwa n'uruganda rusanzwe, kandi ifite imbaraga runaka za mekanike. Muri rusange, ishonga ishobora kwihanganira imbaraga zo gukurura zirenze 147N nibura.
7. Fuse yo mu bwoko bwa drop ya 10kV ishyirwa hanze, kandi intera iri hagati y'ibyiciro irenga cm 70.
