Intsinga z’umuriro uri hagati (MV) ni ngirakamaro cane mu mice y’ugukwiragiza umuyagankuba, mu bisanzwe zikora ku nguvu ziri hagati ya 1 kV na 35 kV. Izo nsinga ni ngirakamaro cane mu gutanga amashanyarazi ata nkomanzi kandi neza kuva ku bibanza vy’amashanyarazi gushika ku bakoresha, ku bibanza vy’inganda, no ku bihimba bitandukanye vy’ibikorwa remezo. Kubera akamaro kavyo, kumenya neza ko intsinga za MV zishobora kwizigirwa kandi zitagira aho zigarukira ni co kintu nyamukuru. Uburyo bumwe nyamukuru bwo kugenzura uko bimeze ni ugupima umuriro mwinshi-. Tuzoca tubona igituma Igerageza ry’Inguvu nyinshi rikenewe ku Mirongo ya MV.
1. Gusuzuma ubutungane bw'imirongo y'ivyuma
Intumbero ihambaye y’igerageza ry’umuriro munini ni ukugenzura ubutungane bw’uburyo bwo gukingira umuriro ku nsinga y’umuriro wa MV. Inenge z’ivyuma nk’ubusa, imivyimba, ubukonje bwinjira, canke amakosa yo mu guhingura bishobora gutuma ivyuma biva mu gice canke bisenyuka vyose, bikaba bituma intsinga zidakora neza. Igerageza ry’umuriro mwinshi ritandukanya izo ngeso mbi mu gutera umukazo ku gipfukisho c’umuriro kirenze urugero rw’umuriro usanzwe, bikaba bifasha kumenya neza intsinga zidahuye n’ingingo mfatirwako z’uburyo.
2. Gutuma imirongo y’imirongo ikora neza kandi yizigirwa.
Intsinga za MV zishirwa mu bisanzwe munsi y’ubutaka canke ahantu kuzisubiriza bizimvye kandi zitwara umwanya-. Iyo izo nsinga zidakora neza, birashobora gutuma amashanyarazi azima, ibikoresho vyononekara, umutekano ukaba uhungabanye, kandi umuntu akabura amahera menshi. Igerageza ry’umuriro munini rituma intsinga zigira inkomezi zihagije zo guhangana n’umuriro ukoreshwa hamwe n’ugutera kw’umuriro kwose kw’igihe gito, bikagabanya ubushobozi bwo gusenyuka kw’ibikorwa. Iryo gerageza rituma abakoresha ubuhinga bwa none bagira icizigiro ku nzira zabo z’imirongo.
3. Kwubahiriza ingingo ngenderwako n'ibisobanuro vy'inganda
Amashirahamwe y’amashanyarazi n’abahinguzi b’imirongo bategerezwa kwubahiriza ingingo ngenderwako zikomeye nka IEC 60502, IEEE 400, n’izindi zisobanura ibisabwa kugira ngo imirongo igeragezwe, harimwo n’igerageza ry’uguhangana n’umuriro mwinshi. Gukora ivyo bipimo bituma umuntu yubahiriza amasezerano n’amategeko, gutyo bikaba bituma igicuruzwa kiba ciza kandi kikamara igihe kirekire.
4. Kumenya ivyononekaye mu gushiramwo
Intsinga za MV zishobora kwononekara mu gihe co gushirwaho kubera gupfukama, gukururwa, canke ibidukikije nk’ugushika kw’ubukonje. Igerageza ry'umuriro munini rikorwa inyuma yo gushiramwo rishobora kumenya utunenge twose twatewe n'ugushiraho-tushobora kuba tutabonetse mu gihe c'isuzuma ry'amaso. Ukwo kumenya hakiri kare bituma habaho igikorwa co gukosora imbere y’uko umuntu atanga inguvu.
5. Ugukingira no gusuzuma uko bimeze
Bishobora kwonona insulation y'imirongo, akenshi ishirwa munsi y'ubutaka canke ahantu aho kuyisubirira bizimvye kandi bitwara umwanya-. Iyo izo nsinga zidakora neza, birashobora gutuma amashanyarazi azima, ibikoresho vyononeka, umutekano ukaba uhungabanye, kandi umuntu akabura amahera menshi. Igerageza ry’umuriro munini rituma intsinga zigira inkomezi zihagije zo guhangana n’umuriro ukoreshwa hamwe n’ugutera kw’umuriro kwose kw’igihe gito, bikagabanya ubushobozi bwo gusenyuka kw’ibikorwa. Iryo gerageza rituma abakoresha ubuhinga bwa none bagira icizigiro ku nzira zabo z’imirongo. Gupima umuriro mwinshi mu bihe bitandukanye nk’igice ca porogarama zo gusanasana bifasha gusuzuma uko intsinga ziguma zimeze, bikaba bituma amashirahamwe y’amazi ashobora gutegura ivyo gusubirira canke gusanura ataco akora aho gufata ingingo iyo hari ikintu kidakora neza.
