Kurinda Umurabyo na Overvoltage Kurinda Imbaraga Nkuru
GPAS ya LV Impamvu zishobora kuba zirenze urugero
GPAS nigikoresho kinini kandi gikora kirinda imirabyo ikomatanya ubushobozi bwubutaka bwo guhagarika ibitero no kwirwanaho arc. Irashobora kugabanya cyane ibyangiritse ningaruka ziterwa nubutaka hamwe namakosa ya arc kubikoresho mugihe uhuye ninkuba.
Iyo inkuba itaziguye ibaye, inkoni yumurabyo cyangwa umuyoboro urinda inkuba birahuzwa, kandi inkuba zikomeye zinjira mumashanyarazi. Iyo imirongo yumurongo mwinshi ifite uburambe bukabije bwumurabyo, umurabyo utemba muri gride yubutaka unyuze kumurabyo. Mugihe ibikoresho bikomeye byo kwivanga nkimashini zo gusudira zikora, imbaraga zikomeye zivanga nazo nazo zizatemba muri gride yubutaka. Umuyoboro ukomeye urashobora gutera amakuru gutakaza amakuru, gukoresha ibikoresho nabi, kugendana ibikoresho, kwangirika kwangiritse cyangwa gutwikwa muri sisitemu yo gutanga amashanyarazi make.
GPAS ifite ubwizerwe buhebuje nigihe gito cyibikorwa, bishobora gutandukanya neza imirasire yumurabyo mwinshi, bikarinda imirabyo kwangiza imiyoboro ikingira ikingira imiyoboro ikingira inkuba, kandi ikirinda neza ko habaho impanuka zituruka kumutekano nkumuriro no guturika.
LOPS yo Kurinda MV Bisi Kurinda
LOPS igikoresho cyo guhagarika ingufu za bisi zirenze urugero zahujwe na bisi, hifashishijwe ikoranabuhanga nk'imashini yihuta, irwanya ingufu nyinshi zidafite umurongo, imiyoboro ihanamye cyane, hamwe no guhagarika ibitero. Irabarwa mubuhanga kandi yateguwe neza. LOPS ikoresha byimazeyo ibiranga volt ampere nziza, ubushobozi bwumuriro mwinshi, hamwe nihuta ryihuta ryumubyigano urenze urugero, ibyuma birwanya umurongo, hamwe nibikoresho byo guhagarika ibitero. Mubisanzwe, gushiraho ibikorwa byibikorwa bya LOPS inshuro 1,2 ya sisitemu yicyiciro cya voltage (irashobora gukoreshwa mubihe bidasanzwe) irashobora kugera kubisubizo byiza mugihe cyo gukora.
LOPS ihujwe mu buryo butaziguye na busbar, ikoresheje ikoranabuhanga nk'ubugenzuzi bwihuse, ingufu nyinshi zidafite umurongo urwanya umurongo, imiyoboro ihanamye cyane, hamwe no guhagarika ibitero. Irabarwa mubuhanga kandi yateguwe neza. LOPS yishyura ibitagenda neza nka SPD, gukingira birenze urugero, hamwe no kurwanya ubushobozi bwa capacitance, bikemura burundu ikibazo cyumuriro mwinshi kuri bisi nini ya voltage.
LOPT ya MV Imirongo Yumurongo Kurinda birenze urugero
35kV ~ 6kV kumurongo wo hejuru mubisanzwe ushyiraho abafata ZnO. Hano hari amakosa aganisha ku kugenda, umurongo wacitse kandi wirabura-hanze.
Kurinda Umurabyo Mushya Kumurongo wohereza hejuru （LOPT） Bishingiye ku ngaruka za cathode, urwego ruto rwinshi rugufi arc guhuha no kuzimya ikoranabuhanga, guca mu mucyo wa voltage iranga abatawe muri yombi ba ZnO, ikoresha ihame ry’imyanya myinshi ya arc guhuha no kuzimya, igishushanyo mbonera cyihariye cyo kwagura inzira ya arc, kugera ku ntego yo guhagarika arc hejuru.
LOPT ifite ibyiza nkumutekano, wizewe, igihe kirekire, no kubungabunga bito. Irashobora kurekura vuba ingufu zumurabyo, ikarinda inkuba no gukandagira, kandi ifite ibikorwa byubusa no kwisukura.
