YSM6-12~24 RMU ifite ubwishingizi bw'umwuka (Ubwoko buhamye)

YSM6-12/24 ubwoko bwa SF6 RMU ifite SF6 load switch nk'ifunguzo nyamukuru, ku kabati kose ikwiriye gukoreshwa mu buryo bwikora mu gukwirakwiza amashanyarazi ndetse no mu byuma bito kandi bishobora kwaguka. Ifite imiterere yoroshye, imikorere yoroshye, uburyo bwizewe bwo guhuza no gushyiraho ibintu byoroshye nibindi, bishobora gutanga imishinga ishimishije ya tekiniki haba ku bikorwa bitandukanye ndetse no ku bakoresha. Hamwe no gukoresha ikoranabuhanga rya sensor na relay yo kurinda igezweho, hamwe n'ikoranabuhanga rigezweho n'umushinga wo guteranya ibintu woroshye.
Ubwoko bwa YSM6-12/24 SF6 RMU bushobora kuzuza ibisabwa byose ku isoko rihora rihindagurika. Bushobora gukoresha SF6-12/24 yikorera ubwayo; Uburyo bwo gukoresha icyuma gikuru imbere mu ruziga rw'impeta bushobora gukoreshwa n'intoki cyangwa hakoreshejwe amashanyarazi. Kandi bushobora kuzuza ibisabwa na "Four Controls" iyo buhujwe na FTU na RTU.

Icyitonderwa: Ku bijyanye no gucika k'umuyoboro mugufi no kugabanya umuvuduko w'amashanyarazi, hashingiwe ku guhuza kwa Fuse plus.

Ku bijyanye n'ishusho y'ikibaho cyo gukwirakwiza

1. Igikoresho cyo gukuraho icyuma gihindura ikoranabuhanga

ibisobanuro by'ibicuruzwa2

Icyitonderwa: Ibikoresho by'inyongera urugero nk'ibifunga inkuba cyangwa switch yo hasi yo gufunga ni amahitamo.

2. Uburinzi bwa fuse-switch

ibisobanuro by'ibicuruzwa3

Icyitonderwa: Ibice by'inyongera urugero nk'ibikoresho bifunga inkuba cyangwa zero sequence CT ni amahitamo.

3. Uburinzi bw'ibice bigabanya urujya n'uruza rw'amashanyarazi

ibisobanuro by'ibicuruzwa4

Icyitonderwa: 1. Kuri HV SF6 circuit breaker, harimo ubwoko bwinshi, ishobora gutoranywa. Ijyanye n'ibyo umukiriya akeneye. (SF1/Schneider, PF/Areva, nibindi). Nanone icyuma gikoresha vacuum circuit breaker nacyo ni amahitamo. (VD4/S-12/24 cyangwa SF6-12/24)
2. Ibindi bice by'inyongera urugero Zero sequence CT irimo gusuzuma nyuma yo kumenyeshwa n'ikigo cyacu.

4. Gupima MV

Icyitonderwa: Ibice by'inyongera urugero nk'ibikoresho bifunga inkuba cyangwa zero sequence CT ni amahitamo.

5. Ibikoresho byo kubikamo bisi (Akabati k'imodoka)

ibisobanuro by'ibicuruzwa6

Icyitonderwa: Ibindi bice by'inyongera ni amahitamo (Gukuraho paneli y'imashini, paneli ya transformer ya Voltage, nibindi)

2. Uburinzi bwa fuse-switch

ibisobanuro by'ibicuruzwa7

Ibice 5 by'ubwoko bwa SF6 ring main unit:

1. Gukuraho switch-disconnector hamwe na switch yo gufunga mu gipangu cyuzuyemo SF6 kandi byujuje ibisabwa na "système pressure yafunzwe".
2. Akabati ka bisi n'akabari kose kari mu murongo umwe utambitse, bityo bigatuma habaho kongera kwagura no guhuza ibikoresho bisanzwe.
3. Akazu ko guhuza kagenzurwa imbere, gahuzwa n'aho hasi hahurira na switch-disconnector na earthing switch (IM cubicles) cyangwa aho hasi hahurira na fuse (PM na QM cubicles). Aka gace kandi gafite icyuma cyo gufunga ubutaka kiri munsi y'amafuru ya MV yo kurinda.
4. Uburyo bwo gukora, guhuza ibintu bikubiyemo ibintu bikoreshwa mu gukoresha switchdisconnector na earthing switch no gushyira mu bikorwa ibimenyetso bihuye (positive break).
5. Gushyiraho agace k'amashanyarazi gafite ingufu nke (imiterere yo hejuru n'iyo hasi) gafite icyuma gikingira umuriro (niba hari moteri), ibyuma bya LV n'ibikoresho bito byo gutwaramo. Niba hakenewe umwanya munini, hashobora kongerwaho agace k'inyongera hejuru y'agace k'inkoni.
6. Ibice by'imashini bishobora gushyirwaho: uburyo bwo kugenzura moteri; ibikoresho bihagarika umuvuduko w'amashanyarazi.

Ikoranabuhanga rizunguruka ry’ibice bitatu rishyirwa mu cyumba cya gaze cyuzuyemo gaze ya SF6 kandi igitutu cyayo ni 0.4 bars. Ifite imikorere myiza kandi ifite umutekano n’ubwirinzi.

● Ubukana:
Icyumba cy'umwuka cyuzuyemo gaze ya SF6, yujuje ibisabwa na "sisteme ifunganye y'umuvuduko", kandi imikorere yo gufunga yaragenzuwe kandi
byagenzuwe mu ruganda.

● Umutekano mu mikorere:
1. Iyi switch ifite imyanya itatu ya "ifunze", "ifunguye" na "ifite hasi", kandi ifite akazi ko gufunga kugira ngo hirindwe ko ikora ku buryo butunguranye. Ikorana nayo riyoborwa no kuzenguruka hakoreshejwe uburyo bwo kubika ingufu z'impeshyi, butagizweho ingaruka n'ibintu bikoreshwa n'abantu.
2. Ifite imikorere yo "kuruhuka" no kwitandukanya.
3. Ubushobozi bwo gukora amashanyarazi make bw'icyuma gifunga ubutaka cya SF6 bwujuje ibisabwa bisanzwe.
4. Mu gihe habaye impanuka, umuvuduko uragabanuka nyuma y’uko umwuka wa SF6 ukabije unyuze mu gice cy’umutekano, maze umwuka ugashyirwa inyuma y’akabati kugira ngo habeho umutekano.
Kurenga ku Ihame:
Gazi ya SF6 ifite ubushobozi bwiza bwo kuzimya arc. Iyo switch ifunguye, urujya n'uruza hagati ya arc na gaze ruzazimya arc. Iyo aho amazi agenda n'aho amazi agenda atandukanijwe, arc igaragara mu butaka bwa electromagnetic bukorwa na magneti ihoraho, kandi arc irareruka kandi ikazimwa iyo umuriro wambuka zeru na gaze ya SF6. Intera iri hagati y'aho amazi agenda n'aho amazi agenda arahagarara irahagije kugira ngo ihangane n'ingufu nyinshi zo kugarura. Sisitemu ni yoroshye kandi yizewe, ifite ubusaza buke bwo gukoranaho kandi imara igihe kirekire.

● Ikimenyetso cyerekana uko Switchgear ihagaze:
Bishyizwe ku gice cyo hejuru cy'umuyoboro w'amashanyarazi, ibi bitanga ikimenyetso gisobanutse cy'aho umuyoboro uherereye. (umugereka A wa IEC 62271-102 isanzwe).
● Igikoresho cyo gukoresha:
Ibi byakozwe hakoreshejwe igikoresho kirwanya refl ex gihagarika igerageza ryose ryo gufungura igikoresho ako kanya nyuma yo gufunga switch cyangwa disconnector yo gufunga.
● Igikoresho cyo gufunga:
Ingufuri ziri hagati ya imwe na eshatu zituma ibi bikurikira bibaho:
● kwinjira mu gice cyo guhinduranya cy'icyuma cyangwa icyuma gihagarika uruziga
● kwinjira mu gice cyo gusimbuza cy'icyuma gihagarika ubutaka
● Gukoresha buto yo gufungura. ● Guhindura byoroshye kandi byoroshye
Igenzura rya mekanike n'amashanyarazi riri iruhande rw'imbere, ku gice cy'imbere kirimo imbonerahamwe igaragaza uko igikoresho gihagaze (gifunze, gifunguye, cyakuweho ivu):
● Bifunze:
Umugozi uyobora ukoreshwa mu buryo bwihuse, utitaye ku mukoresha. Nta ngufu zibikwa muri uwo muyoboro, uretse igihe ibikorwa byo guhinduranya birimo kuba.
Ku byuma bihuza ibyuma, uburyo bwo gufungura buba bufite intwaro mu gihe kimwe n'aho ibyuma bifunga.
● Gufungura:
Ifunguzo rifungurwa hakoreshejwe uburyo bumwe bwo gukora vuba, bukorera mu cyerekezo gitandukanye.
Ku gice cy’amafurushi ahuza switch, gufungura bigenzurwa na:
● akabuto ko gukanda
● ikosa.
● Gutunganya ubutaka:
Umugozi wihariye ugenzura utuma habaho gufungura cyangwa gufunga kw'imigozi y'ubutaka. Kugera kuri uyu mugozi bifungwa n'igipfundikizo gishobora gusubizwa inyuma niba switch ifunguye ariko igakomeza gufungwa mu mwanya wayo niba ifunze.
Ikimenyetso cy'uko umuriro uhari
Iki gikoresho gifite amatara yo mu bwoko bwa VPIS (Voltage Presence Indicating System), hakurikijwe ibipimo ngenderwaho bya IEC 61958, bituma ingufu z'amashanyarazi zigenzurwa ku nsinga.
Kutita ku bidukikije
● Inzu ifunze imbere, irimo ibice bikora bya LBSkit
(switch, disconnector yo gukurura imyuka). Yujujwemo SF6 hakurikijwe ibisobanuro biri mu nama ya IEC 62271-200 ku “buryo bw’imivuduko bufunze”.
Gufunga bigenzurwa mu buryo bunoze mu ruganda.
● Ibice byakozwe kugira ngo bibone uburyo bwiza bwo gukwirakwiza amashanyarazi.
