Ikoreshwa rya ASJ Ibisigisigi Byubu muri Generator Gushiraho Umushinga muri Malidiya

1.Icyegeranyo rusange

Uyu mushinga uherereye muri Malidiya. Intego yibisigisigi bya relay yashyizweho ni ukumenya ibisigisigi bigereranywa no kugereranya agaciro gasigaye hamwe nagaciro fatizo. Mugihe agaciro gasigaye gasigaye karenze agaciro shingiro, kazohereza ikimenyetso cyumukanishi kuri off-off (kugirango imashini ihindurwe ikubye cyangwa igikoresho cyo gutabaza acousto-optique yohereze impuruza) .Icyerekezo gisanzwe gisanzwe hamwe na voltage yamashanyarazi cyangwa umuyagankuba muke, nibindi byahujwe nibikoresho bisigaye birinda ibyuma bisigara, cyane cyane bikoreshwa kuri ac 50 hz, igipimo cya voltage 400 v no munsi yumuzunguruko wa sisitemu ya TT na TN, ikoreshwa mukurinda amashanyarazi amashanyarazi, gukumira ibikoresho byatewe nubutaka bwumuriro n amashanyarazi impanuka yumuriro, irashobora kandi gukoreshwa mugutanga amakuru ataziguye kubantu kugirango bakingire ingaruka zamashanyarazi, bityo rero ikoreshwa cyane muri sisitemu yo gutanga amashanyarazi no gukwirakwiza.

2.Ibikoresho byinshi byo gukoresha ibisigisigi byubu

2.1 Kurinda Amashanyarazi ataziguye

Igipimo cyo guhuza amashanyarazi mu buryo butaziguye ni uguhita uhagarika amashanyarazi. " ibikoresho. Nk’ubushakashatsi, agaciro keza ka contact za voltage ni 50V. Kubwumutekano wumuntu ku giti cye, mugihe kunanirwa kwizuba bibaye mugice icyo aricyo cyose cyigikoresho cyamashanyarazi, iyo voltage yo guhuza irenze 50V, birakenewe guhita uhagarika igice cyamakosa yumuriro mugihe cyagenwe. Igikoresho kirengera-kirenze kugarukira kumashanyarazi nibikoresho hamwe nigikorwa cyacyo bwite, kandi ntishobora guhita ihagarika amashanyarazi. Igikoresho gisigaye cyokwirinda ntigishobora guhindurwa numuyoboro wumutwaro kandi kirashobora gukoreshwa hamwe nigikoresho kirenga kirenze icyerekezo cyo gukingira amashanyarazi mu buryo butaziguye.

2.2 Kurinda amakosa

Impamvu ni ihuriro hagati yumuyobozi muzima nisi, igishishwa cyicyuma cyangwa ikintu cyahujwe nubutaka. Kunanirwa kwayo birashobora gutuma umuntu ahitanwa n’amashanyarazi n’ibikoresho byangiritse, kandi bishobora guteza umuriro w’amashanyarazi mu bihe bikomeye. Kurinda amakosa kubutaka byahoze bikingirwa nibikoresho birenze urugero. Iyo ikosa ryikosa rirenze agaciro kagenwe kubikoresho birenga-bigezweho byo kurinda, umuzenguruko wamakosa ucibwa nigikoresho cyo kurinda kirenze.

Muri sisitemu ya TT, umurongo ufite ibipimo binini byerekanwe kandi birebire umurongo wo gukwirakwiza, amakosa yo gutwarwa nuyobora ubuzima, amakosa yo mu butaka adafite umutekano hamwe n’ikosa rya arc muri sisitemu ya TN birashobora kubaho ko ikosa ryikosa ritari munsi yimiterere yuburinzi burenze urugero Igikorwa, hamwe nigikoresho kirenze-igikoresho cyo kurinda ntigikora. Igikoresho gisigaye kirinda ibikoresho, cyangwa icyuma cyumuzingi hamwe nuburinzi bwubutaka, burashobora gukora neza kurinda amakosa yubutaka.

2.3 Kurinda umuriro w'amashanyarazi

Umuriro w'amashanyarazi ubusanzwe uterwa numuyoboro mugufi w'amashanyarazi, urimo ibyuma bigufi byumuzingi hamwe na arc bigufi. Iyambere ni umuzunguruko mugufi hagati yabayobora bizima (nko hagati yicyiciro, hagati yicyiciro na N imirongo). Ikosa ryikosa ribarwa muri kilo ampere. Ubushyuhe bwo hejuru buroroshye gutera okiside ya insulation no gutwikwa kwizana.

Nubwo impanuka y’umuriro ari nini, irashobora gukingirwa n’umuriro w’umuzunguruko hamwe na fuse hamwe n’uburinzi buke bw’umuzunguruko, kandi amashanyarazi arahagarikwa n’ibikorwa ako kanya byangiza amashanyarazi kugirango birinde umuriro. Iheruka ni umuyoboro muzima uzunguruka kubutaka, cyane cyane arc nkinzira, nubwo ikosa ryikosa ari rito, ariko kuruhande rumwe, arc imara igihe kirekire, ubushyuhe bwaho buri hejuru, biroroshye gutwika ibikoresho bikongoka kandi bigatera umuriro. Kubwibyo, impanuka yumuriro iterwa na arc ya short short circuit irarenze cyane iy'icyuma kigufi. Imashanyarazi yamashanyarazi hamwe nibikorwa bisigaye byo gukingira ibikorwa birashobora guhagarika umuzunguruko udashyigikiwe nigikoresho cyokwirinda kirenze urugero kugirango wirinde umuriro wamashanyarazi uterwa numuyoboro mugufi wa arc.

3.ASJ Urukurikirane rwibisigisigi byubu

3.1 Icyitegererezo & Imikorere

3.2 Ibipimo bya tekiniki

3.3 Igishushanyo gisanzwe cyo gusaba

4.Amashusho yo kwishyiriraho ibyasigaye byerekanwa kuri generator yashizeho urubuga

5. Incamake

Acrel ASJ yuruhererekane rwibisigisigi byasigaye byakoreshejwe mubihe byinshi, nkinganda, ubwenegihugu, metero, inyubako yubwenge nibindi, byagize ingaruka nziza zo gukingira kandi bikwiye gukoreshwa mukwamamaza.
