Cikakken Ayyukan Mahimmanci

1. Ƙarfafa siginar martani na ƙarfin lantarki

IS200EXIBG1A tana karɓar sigina na amsawa mai ƙarfi kai tsaye daga gadar SCR mai ban sha'awa ta hanyar haɗin stab biyar (E1 ta E5):

• E1 (VA), E2 (VB), E3 (VC) : Abubuwan shigar wutar lantarki na layi-zuwa-layi AC guda uku, kewayon ƙima 240 zuwa 600 V rms, 50/60 Hz.

• E4 (VP) : DC ingantacciyar shigar da wutar lantarki ta bus, wanda matsakaicin matakin ƙarfinsa ya ƙayyadad da ƙarfin shigarwar AC mai hawa uku.

• E5 (VN) : Shigar da wutar lantarki mara kyau ta DC.

Kowace siginar wutar lantarki guda biyar tana wucewa ta hanyar cibiyar sadarwa mai rarraba wutar lantarki mai zaman kanta don daidaitawa, tare da kowace hanyar sadarwa tana nuni zuwa ƙasan chassis. Ana aika siginar analog ɗin da aka raba, daidai da ƙarfin ƙarfin gada, zuwa allon EXIC ta hanyar madaidaitan fil na kebul mai sarrafa nau'ikan J1 (wanda ake auna akan layi a TP502 zuwa TP506). Wannan hanyar rarraba wutar lantarki mai wucewa ba ta buƙatar ƙarin keɓancewar amplifiers, yana haifar da tsari mai sauƙi da ƙarfi.

2. Tashin Hankali na Yanzu

Ana gabatar da siginar amsawa ta halin yanzu ta hanyar haɗin J2. Wannan siginar ta samo asali ne daga shunt na DC da aka haɗa a cikin jeri tare da tabbataccen tashar fitarwa na DC na gadar tashin hankali. Siffar fitarwar shunt ita ce: 100 mV fitarwa yayi daidai da 100% na ƙimar halin yanzu (gudanar da ke gudana a cikin hanya ɗaya kawai).

Siginar shunt yana ɗaukar sarkar sarrafawa mai zuwa akan allon IS200EXIBG1A:

• Tace Noise : Yana hana tsangwama mai girma.

• Amplifier Voltage : Yana haɓaka siginar matakin mV zuwa matakin da ya dace da aiki.

• Canza-ƙarfi-zuwa-Frequency Converter (VF) : Kai tsaye yana jujjuya wutar lantarki ta analog zuwa siginar mitar.

Kwamitin yana fitar da siginonin mitar matakan tunani guda biyu:

• Siginar martani na yanzu (IFB, mai aunawa a TP509) : Yana ba da ra'ayi ga mai sarrafa filin yanzu, tare da kewayon kusan 2.5 PU daidai da 2 MHz.

• Siginar Saƙon Saƙon Model Tsare-tsare (ITOC, wanda za'a iya aunawa a TP510) : Yana da kewayon siginar martani na yanzu sau biyu, kusan 5.0 PU daidai da 2 MHz, ana amfani dashi don ƙirar kariya ta wuce gona da iri.

Ana aika dukkan sigina zuwa allon EXIC ta hanyar kebul na J1.

3. MOV Fuse Loss Ganewa

Uku Metal Oxide Varistor (MOVs) suna cikin gadar SCR mai ban sha'awa, an haɗa su a kan layin AC mai hawa uku don ɗaukar wuce gona da iri. Kowane MOV yana da fuse mai karewa a layin shigar sa. IS200EXIBG1A tana tattara siginonin ƙarfin lantarki na layi akan gefen lodi na fis ɗin uku ta hanyar haɗin kai tsaye guda uku (E10 don VMA, E11 don VMB, E12 don VMC), kama daga 240 zuwa 600 V rms a 50/60 Hz.

Da'irar gano asarar fiusi a kan jirgin yana ci gaba da kwatanta matsayin ƙarfin lantarki mai kashi uku. Idan ɗaya daga cikin fuses guda uku ya busa, da'irar ganowa daidai ta canza yanayin yanayin yanayin fitarwa, yana ba da rahoton laifin ga hukumar EXIC ta layin siginar MOV a cikin kebul na J1 (ana iya aunawa a TP508, ƙaramin matakin yana nuna fuse Ok). Ana ba da alamun LED guda biyu a gaban panel: jajayen hasken MNOK (DS41) yana haskakawa don nuna fuse ya busa, kuma koren MOK haske (DS42) yana haskaka lokacin da fis ɗin yayi kyau, yana ba da ingantaccen yanayin duba wurin dubawa.

4. Kofar Kofar SCR

Hukumar IS200EXIBG1A tana haɗe da keɓaɓɓen keɓaɓɓen keɓancewar kofa SCR ƙofar bugun bugun bugun jini da'irori. Kowane da'irar yana karɓar umarnin ƙofar dabaru-matakin TTL daga hukumar EXIC (GATE1C ta hanyar GATE6C, daidai da SCR1 ta hanyar SCR6) ta hanyar kebul na J1. Bayan opto-keɓewa da haɓaka wutar lantarki, yana fitar da daidaitaccen SCR ta hanyar haɗin fitarwa na kofa shida J3 zuwa J8.

Halayen fitarwa na kowane da'irar direban ƙofar sune:
