Igikoresho cyo gusimbuza cya GCS gifite Voltage nkeya gitanga imbaraga mu gukwirakwiza ingufu nkeya mu rwego rw'inganda

Nk'igikoresho cyo gukwirakwiza ingufu nkeya kandi gitanga ingufu nkeya, GCS Low-Voltage Drawer-Type Switchgear yagenewe gusa sisitemu z'amashanyarazi za AC zifite ibyiciro bitatu, ikabasha gukora imirimo myinshi irimo gukwirakwiza ingufu, kugenzura moteri hamwe no kwishyura ingufu zikoreshwa. Yakozwe hakurikijwe cyane IEC439-1 Low-Voltage Switches na Controlgear hamwe na JB/T9661 Low-Voltage Drawer-Type Switchgear, ifite imikorere myiza n'imiterere y'imiterere ijyanye n'ibisabwa cyane mu gukwirakwiza ingufu mu rwego rw'inganda, bigatuma iba amahitamo y'ingenzi kuri sisitemu zo gukwirakwiza ingufu nkeya mu nganda zitandukanye.

I. Aho ibicuruzwa by'ingenzi biherereye

Ibi bikoresho bikoreshwa mu gutanga amashanyarazi no kuyatanga hamweinshuro eshatu za AC 50/60Hz, ifite voltage y'akazi ya 380V (400)/660V n'umuvuduko w'amashanyarazi wa ≤4000A, kandi ishobora guhindurwa kugira ngo ihuzwe n'ihitamo ry'imashini zikwirakwiza za 2500kVA no munsi yayo. Ifite akabati k'ingurane ka capacitor n'akabati k'ingurane kakozwe mu buryo bwihariye, ibi bikoresho bishobora guhaza neza ibisabwa mu gutanga amashanyarazi no kunoza ingufu, bihuza imikorere myiza y'ikwirakwizwa ry'amashanyarazi n'ikiguzi cy'ishoramari ryuzuye.

II. Imiterere y'Ikoreshwa mu Buryo Bugari

Kubera ko byizewe cyane kandi bihuzwa n’imikorere y’ikoranabuhanga, iki gicuruzwa gikoreshwa cyane mu nganda no mu bihe bitandukanye bifite ibisabwa bikomeye kugira ngo ingufu zikwirakwizwe neza:

1.Urwego rw'amashanyarazi: Sisitemu zo gukwirakwiza ingufu z'amashanyarazi n'amashanyarazi zifite ingufu nke;

2.Inganda zikomeye: Gukwirakwiza ingufu n'igenzura rya moteri mu nganda zirimo peteroli, imiti, ibyuma n'imyenda;

3.Urwego rw'ibikorwaremezo n'ubwubatsi: Sisitemu zo gukwirakwiza ingufu z'amashanyarazi make mu nyubako ndende;

4.Urwego rukora cyane mu buryo bwikora: Ibintu bikenewe cyane mu kugenzura ahantu hamwe nk'inganda nini z'amashanyarazi na sisitemu za peteroli.

III. Ibipimo by'ingenzi bya tekiniki

Icyiciro cy'ibipimo	Ibipimo byihariye
Voltage ifite amanota	Umuyoboro mukuru: AC 380 (400)V, 660V; Urugendo rw'inyongera: AC 220V, 380(400)V / DC110V, 220V; Voltage yo gufunga: 660(1000)V
Inshuro zipimwe	50(60)Hz
Ingano y'ubushyuhe	Insinga zitambitse ≤4000A; Udusanduku twa bus duhagaze (MCC) 1000A
Umuyoboro wa Busbar Wihangana n'Umuriro	Guhangana mu gihe gito: 50, 80kA/1s; Guhangana mu gihe gito: 105, 176kA/0.1s
Igeragezwa ry'ingufu z'amashanyarazi	Urugendo rukuru 2500V/umunota 1; Urugendo rw'inyongera 1760V/umunota 1
Ishuri ry'Uburinzi	IP30, IP40 (ni ngombwa)
Sisitemu ya Busbar	Insinga enye z'icyiciro cya gatatu (A, B, C, PEN); Insinga eshanu z'icyiciro cya gatatu (A, B, C, PE, N)

IV. Ibyiza by'Imiterere n'Imikorere

1.Udukingirizo tw'uburyo bukomeye: Urufunguzo rw'ingenzi rukozwe mu cyuma cya 8MF gifite imyobo ya 20mm modular installation, gishyigikira imiterere ibiri yo guteranya no gusudira igice. Ingano z'akabati zigenwa kugira ngo zihuze n'imiterere itandukanye yo gushyiraho.

2.Kwitandukanya kw'ibice by'imikorere byigenga: Icyumba cy'ibikoresho bikora neza, icyumba cya bisi n'icyumba cy'amashanyarazi bigabanyijemo ibice bikomeye, buri gice gifite imirimo yihariye, ibi bikarinda ikwirakwira ry'amakosa no kunoza umutekano w'imikorere.

3.Igishushanyo mbonera cy'ubwoko bw'akabati gashobora koroha: Uburebure bw'agasanduku gashingiye kuri module ya 160mm, kandi utubati dufite imiterere itandukanye dufite ubushobozi bwo gusimburana. Dufite ibikoresho bihuza ibyuma n'ibimenyetso bisobanutse byo gufungura/gufunga, kugerageza no gukuramo, ibi bikoresho bitanga icyizere cyo gukora neza no kubungabunga byoroshye. Akabati kamwe ka MCC gashobora kwakira utubati tugera kuri 22.

4.Ibikoresho by'ubwiza n'utubari tw'imodoka: Udusanduku tw’umuringa ukomeye twa TMY-T2 dukoreshwa mu bikoresho byose, hamwe n’ibice bifatanye; utusanduku tw’umuringa dufite uburebure bwose bukozwe mu macupa/ifeza ni amahitamo kugira ngo twongere ubushyuhe n’imbaraga. Ibice by’amashanyarazi by’ingenzi bitoranywa mu buryo bw’ikoranabuhanga bwo mu gihugu n’ubwo mu mahanga bufite ubushobozi bwo guhindura ibintu, bushyigikira kuvugurura no gusimbuza ibice.

5.Guhuza imbaraga cyane n'uburyo zikwirakwizwa: Ibikoresho bishobora guhuzwa mu buryo bworoshye na transfoma zumutse n'izicukurwa mu mavuta. Igice cy'insinga gifite ubugari bubiri bushobora gukoreshwa bwa 240mm na 440mm, bityo bikaba byoroshya gushyiraho no kubungabunga insinga. Hagati aho, amashanyarazi ya 24V adakomeye arahari kugira ngo yuzuze ibisabwa mu buryo bwikora na sisitemu za mudasobwa.

Ifite imiterere y'ingenzi yo kwizerwa cyane, koroherana cyane no kubungabunga byoroshye, GCS Low-Voltage Drawer-Type Switchgear ipima imikorere myiza y'amashanyarazi n'umutekano mu mikorere. Ishobora gushyirwa mu buryo bworoshye hakurikijwe ibyo inganda zitandukanye zikenera mu gukwirakwiza ingufu, itanga ubufasha buhamye kandi bunoze ku bikoresho bikwirakwiza ingufu nke mu nganda, inyubako ndende, amashanyarazi n'ibindi.
