Jagoran Matsalar Matsalar Wutar Lantarki Main Elevator - Babban Da'irar (MC)

1 Bayani

Da'irar MC ta ƙunshi sassa uku:sashin shigarwa,babban sashin kewayawa, kumasashen fitarwa.

Sashen shigarwa

• Yana farawa daga tashar shigar da wutar lantarki.

• Yana wucewaAbubuwan EMC(fita, reactors).

• Haɗa zuwa tsarin inverter ta hanyar lambar sadarwa mai sarrafawa#5(ko module rectifier a cikin tsarin sabunta makamashi).

Babban Sashe na Da'ira

• Abubuwan da ake buƙata sun haɗa da:

  • Mai gyarawaYana canza AC zuwa DC.

    • Rectifier mara sarrafawa: Yana amfani da gadojin diode (babu buƙatun tsarin lokaci).

    • Sarrafa Mai Gyara: Yana amfani da kayan aikin IGBT/IPM tare da kulawa mai saurin lokaci.

  • DC Link:

    • Electrolytic capacitors (jeri-haɗe don tsarin 380V).

    • Resistors masu daidaita ƙarfin lantarki.

    • Na zaɓiregeneration resistor(don tsarin da ba a sake farfadowa ba don watsar da makamashi mai yawa).

  • Inverter: Yana canza DC zuwa AC mai canzawa don motar.

    • Hanyoyin fitarwa (U, V, W) suna wucewa ta cikin DC-CTs don amsawa na yanzu.

Sashen fitarwa

• Yana farawa daga fitarwar inverter.

• Yana wucewa ta DC-CTs da abubuwan EMC na zaɓi (reactors).

• Yana haɗi zuwa tashoshin mota.

Mabuɗin Bayanan kula:

• Polarity: Tabbatar da daidaitattun haɗin "P" (tabbatacce) da "N" (mara kyau) don masu iya aiki.

• Hanyoyin SNUBBER: An shigar a kan IGBT/IPM modules don murkushe ƙarfin wutar lantarki yayin sauyawa.

• Siginonin sarrafawa: Ana watsa siginar PWM ta igiyoyi masu murɗaɗɗen igiyoyi don rage tsangwama.

2 Gabaɗaya Matakan Magance Matsalar

2.1 Ka'idoji don Ganewar Laifi na MC

1. Duban Sirri:

   • Tabbatar cewa duk matakai uku suna da sigogin lantarki iri ɗaya (juriya, inductance, capacitance).

   • Duk wani rashin daidaituwa yana nuna kuskure (misali, diode mai lalacewa a cikin gyara).

2. Yarda da Tsarin Mataki na Mataki:

   • Bi zane-zanen wayoyi sosai.

   • Tabbatar gano lokacin tsarin sarrafawa ya daidaita tare da babban kewaye.

2.2 Ikon Rufe-Madauki

Don ware kurakurai a tsarin rufaffiyar madauki:

1. Cire haɗin Motar Tafiya:

   • Idan tsarin yana aiki kullum ba tare da motar ba, laifin yana cikin motar ko igiyoyi.

   • Idan ba haka ba, mayar da hankali kan majalisar kulawa (inverter/rectifier).

2. Saka idanu Ayyukan Masu Tuntuɓa:

   • Don tsarin sabuntawa:

     • Idan#5(Input contactor) tafiye-tafiye kafin#LB(brake contactor) yana shiga, duba mai gyarawa.

     • Idan#LByana shiga amma matsalolin sun ci gaba, duba inverter.

2.3 Binciken Lambar Laifi

• Lambobin allo na P1:

  • Misali,E02(mafi yawa),E5(DC link overvoltage).

  • Share kurakuran tarihi bayan kowane gwaji don ingantaccen ganewar asali.

• Lambobin Tsarin Gyarawa:

  • Duba jeri tsakanin grid ƙarfin lantarki da shigar da halin yanzu.

2.4 (M) Laifin Yanayin ELD

• Alamun: Tsayawa kwatsam yayin aiki mai ƙarfin baturi.

• Tushen Dalilai:

  • Bayanan awo na kaya mara daidai.

  • Saurin karkatar da ma'aunin wutar lantarki.

• Duba:

  • Tabbatar da ayyukan tuntuɓar da ƙarfin fitarwa.

  • Saka idanu lambobin allon P1 kafin rufewar (M) ELD.

2.5 Binciken Laifin Mota

3 Laifi gama gari & Magani

3.1 PWFH(PP) Mai Nuna Kashe ko walƙiya

• Dalilai:

  1. Asarar lokaci ko jerin kuskure.

  2. Kuskuren allon kulawa (M1, E1, ko P1).

• Magani:

  • Auna ƙarfin shigarwar shigarwa da daidaitaccen tsari na lokaci.

  • Sauya allo mara kyau.

3.2 Rashin Gasar Koyon Iyalan Gindi na Magnetic

• Dalilai:

  1. Kuskuren maɓalli (amfani da alamar bugun kira don bincika tatsuniyoyi).

  2. Lallatattun igiyoyi masu ɓoye.

  3. Kuskuren encoder ko allon P1.

  4. Saitunan ma'auni mara daidai (misali, saitin motsin motsi).

• Magani:

  • Sake shigar da rikodi, maye gurbin igiyoyi/ allo, ko daidaita sigogi.

3.3 Laifin E02 (Mai wuce gona da iri).

• Dalilai:

  1. Poor module sanyaya (masoya toshe, m thermal manna).

  2. Rashin daidaitawar birki (ratar: 0.2-0.5mm).
