Itsinda rikuru ry’ingunguru ni itsinda ry’ibikoresho by’amashanyarazi byo kohereza no gukwirakwiza (switchgear ifite voltage nyinshi) bishyirwa mu kabati k’icyuma cyangwa kadafite icyuma cyangwa bigakorwamo icyuma gitanga amashanyarazi. Igice cyacyo cy’ibanze gikoresha uburyo bwo gukwirakwiza amashanyarazi kandi Fuse ifite ibyiza byo kuba imiterere yayo yoroshye, ingano nto, igiciro gito, ishobora kunoza ibipimo by’amashanyarazi n’imikorere yayo, ndetse n’umutekano w’amashanyarazi. Ikoreshwa cyane mu dusanduku two gukwirakwiza amashanyarazi n’udusanduku tw’udusanduku two gukwirakwiza amashanyarazi mu turere tw’imijyi, inyubako ndende, inyubako nini za leta, inganda n’ibigo by’ubucuruzi.
Ubwoko butandukanye bw'utubati tw'urushundura
Ubwoko bwa HXGN-10
(H-Ring Main Unit; X-box type; G-fixed type; N-indoor) Imiterere y'akabati iteranywa hakoreshejwe ibyuma bipfunyika kandi bisudira, kandi urwego rwo kurinda ni IP2X. Igice cyo hejuru cy'akabati ni icyumba cya busbar, kandi icyumba cy'ibikoresho kiri imbere y'icyumba cya busbar, gitandukanyijwe n'ibyuma. Hagati y'akabati ni icyumba cyo gusimbuza imizigo, kandi igice gikingira imizigo gishyizwe hagati y'icyuma gisimbuza imizigo n'ibindi bice. Ku kabati k'insinga kinjiriramo n'igisohoka, hepfo y'akabati hari icyuma gipfundikira gishobora gukurwaho; ku kabati k'imbere kinjiriramo n'igisohoka, hejuru y'akabati hashobora gushyirwaho imiyoboro ya bisi cyangwa udukingirizo two gukingira.
Ubwoko bwa HXGN-10
Igice kinini cy’impeta y’umwuka ya HXGN-10 gifite gahunda 15, muri zo gahunda 01 ikaba akabati k’ifuru y’umuzigo; gahunda 02 ikaba akabati k’umuzigo, byombi bifite ibikoresho byo gusimbuza hasi; gahunda 09 ikaba akabati k’umuzigo.
Igikonoshwa cy'uru ruhererekane rw'akabati k'uruhererekane rw'impeta gikoresha icyuma gifunga plaque no gufatanya na vis kugira ngo kibe icyuma gifunze neza. Umubiri w'akabati ugizwe n'ibice bine bihagaze, igifuniko cyo hejuru, hasi hepfo, imbere, inyuma, ku ruhande, nibindi. Imbere y'akabati k'imashini ikoresha vis ifite inzugi ebyiri zo hejuru n'izo hepfo zifatanye na vis; imbere y'akabati k'imashini ikoresha vis ifite inzugi 3. Hari idirishya ryo kureba aho vis ikoresha vis n'aho vis iherereye; isano iri hagati y'akabati n'akabati ni mu buryo bwo gufunga plum contact, kandi vis ifite icyuma gikingira. Agasanduku k'ibikoresho gashobora kongerwaho hejuru y'akabati hakurikijwe ibyo umukoresha akeneye.
Imashini ikoresha amashanyarazi ishyirwa mu kabati k'umuyoboro w'impeta ikora gaze, nta mavuta kandi ntabwo ihumanya; igikoresho gikoreshwa n'intoki n'amashanyarazi ni uburyo bwo kubika ingufu mu muyoboro wa torsion, bufite imiterere yoroshye kandi bufite imbaraga nke.
Hari ibikoresho bihuza ibyuma hagati y’imashini ikoresha umutwaro, imashini ikoresha ubutaka n’imashini y’imbere. Imikoranire hagati yabyo ni iyi ikurikira:
1) Nyuma yuko swichi yo gufunga ifunze, swichi yo gupakira imizigo ntishobora gukoreshwa, kandi igice cy'imbere gishobora gufungurwa;
2) Nyuma yo gufungura icyuma gifunga ubutaka, icyuma gifunga imizigo gishobora gukoreshwa, ariko igice cy'imbere ntigishobora gufungurwa;
3) Nyuma yo gufungura swichi yo gushyiramo ibikoresho, swichi yo hasi ishobora gukoreshwa kandi igice cy'imbere gishobora gufungurwa;
4) Nyuma yuko swichi yo gushyiramo imizigo ifunze, swichi yo gufunga icyuma ntishobora gukoreshwa kandi igice cy'imbere ntigishobora gufungurwa.
Ubwoko bwa GE
Iyi ni moderi iturutse mu mahanga, ikoresha switch ya SF6. Uburyo bwo kuyikoresha ni ubwoko bwo kubika ingufu z'impeshyi, ifite igikoresho cyo kuyifunga vuba kandi gifungura vuba. Uburyo bwo kuyifungura bubikwa mu buryo bwikora n'impeshyi mu gihe cyo kuyifunga, kandi gucika kwayo bigenzurwa (bikozwe) na coil yo kuyifungura cyangwa fuse ya HRC.
SF6 ni uburyo bwo gukurura imizigo, agasanduku ka gaze gasukwa hakoreshejwe laser y'icyuma kidashonga, gusudira umwuka udafunga neza, nta gasket zisohoka cyangwa zifunga; muri zo, 8DJ20 ni imiterere y'agasanduku ka gaze gasanzwe idashobora kwaguka; 8DH10 ni ubwoko bushobora kwaguka; ikoresha igishushanyo mbonera cya modular kugira ngo ihuze n'ibikenewe bitandukanye. Ibikenewe n'abakoresha terminal na ring network. Ifite ibyiza byo kuba imiterere mito, imiterere mito, kandi idakoreshwa mu kubungabunga.
Igikoresho cyo kurinda
Hashingiwe ku bunararibonye bw'imyaka myinshi bw'ibikoresho byo mu gihugu no mu mahanga mu bikoresho birinda mudasobwa ntoya by'icyuma gikuru cy'impeta, hamwe n'imiterere nyayo ya sisitemu yo mu gihugu ihujwe n'ikoranabuhanga, ni ibikoresho by'ikoranabuhanga rigezweho bikoresha ikoranabuhanga rigezweho rihuza uburinzi, igenzura, kugenzura, itumanaho n'ibindi bikorwa. Ibikoresho by'amashanyarazi byiza ku bikoresho by'ikoranabuhanga bikoresha ikoranabuhanga. Ibi bikoresho bifite isomero ry'uburinzi ryubatswemo rigizwe na gahunda zirenga 20 zisanzwe zo kurinda, rifite imikorere yuzuye kandi ikomeye yo gukusanya voltage, ingano ya analog y'amashanyarazi n'ingano ya switch y'ibikoresho by'ibanze (ibipimo by'amashanyarazi bigerwaho na CT yo kurinda)
Uburinzi bwa mudasobwa ziciriritse
Kubera ko igice cy’ingenzi cy’impeta gikoreshwa n’amashanyarazi menshi, hakenewe igikoresho cyo kurinda kugira ngo kirinde igice cy’ingenzi cy’impeta. Gukoresha ibikoresho byo kurinda mudasobwa nto mu gice cy’ingenzi cy’impeta biri kugenda bikundwa cyane. Bitewe n’uko igice cy’ingenzi cy’impeta ari gito kandi kikaba gihendutse, hakenewe igikoresho cyo kurinda mudasobwa nto gihendutse kandi gifatika.
Ingano y'ikoreshwa: ikoreshwa cyane cyane ku mishinga y'abakoresha nka 10KV;
Igice cyo kurinda: uruziga, icyuma gifasha gusimbuza transformer, moteri, capacitor, reactor, icyuma gifasha gusimbuza gikoresha amashanyarazi, PT, kitari amashanyarazi;
Ishusho y'igicuruzwa: Umubiri muto cyane uri muri mm 100 ukwiriye cyane cyane ku makabati nk'amakabati y'urusobe rw'impeta;
Ibikoresho by'umusaruro: igishishwa cy'icyuma gikozwe mu cyuma, ikizamini cyo kurwanya amashanyarazi gihuye n'amahame y'igihugu;
Urusobe rw'imikorere: Hatabayeho kurwanya gusimbuka, rushobora gukoreshwa hamwe n'amaswichi atandukanye hamwe no kurwanya gusimbuka;
Itumanaho: ni ngombwa kuri interineti y'itumanaho ya RS485 cyangwa ntayo.
Porogaramu:
Imashini nyamukuru y’impeta ntimaze igihe kinini igaragara, ariko imaze gukoreshwa cyane. Ibi biterwa ahanini n’inyubako nshya z’inganda n’ibigo. Ukurikije uburyo bwo gutanga amashanyarazi no gukwirakwiza, muri zo, ubushobozi buke ni bwo bwinshi. Transformateur ikwirakwiza muri rusange ntirenga 1250KVA, amashanyarazi ahoraho igihe kirekire, n’amaswichi afite ingufu nyinshi ntabwo akoreshwa kenshi. Kuri ubu bwoko bw’abakoresha, imikorere y’imashini nyamukuru y’impeta ntabwo itunganye, ariko irahagije. Hamwe n’inyubako nini z’umujyi, hamaze kubakwa inyubako nyinshi nini ndende, kandi sitasiyo zisanzwe akenshi ziba ziri hasi. Dukurikije ibisabwa mu kurinda inkongi, sitasiyo n’ibikoresho byo gukwirakwiza bigomba kuba “bidafite amavuta” kandi bigakoreshwa mu buryo bukwiye hakurikijwe ubuso bw’inyubako. , Transformateur n’ibikoresho byo gukwirakwiza bigomba kuba “bito”, bityo akabati k’impeta cyangwa imashini zigabanya umuriro, transformateur z’ubwoko bwumye, na transformateur z’ubwoko bwumye byinjiye muri buri nyubako. Akabati k’impeta gafite imiterere yoroshye, imikorere yizewe kandi itekanye, isuku nto, n’igiciro gito cyo gukora. Ugereranyije n'utubati tw'impeta dufite utumashini duhagarika imiyoboro y'amashanyarazi, dufite ibyiza bidasanzwe. Igice cy'ingenzi cy'impeta gisaba ko impeta y'impeta igira imikorere myiza kandi ntoya. Ubwoko bushya bw'impeta y'impeta bwaje kubaho, ari nabyo byatumye ikoranabuhanga ritera imbere. Igice cy'ingenzi cy'impeta y ...
