I-Elevator Main Electrical Circuit Troubleshooting Guide - Main Circuit (MC)

1 Uhlolojikelele

Isekethe ye-MC inezingxenye ezintathu:ingxenye yokufaka,ingxenye enkulu yesifunda, futhiingxenye yokuphumayo.

Isigaba Sokufaka

• Iqala kusukela kumatheminali okokufaka amandla.

• IyadlulaIzingxenye ze-EMC(izihlungi, ama-reactor).

• Ixhuma kumojula yokuguqula nge-contactor yokulawula#5(noma imojuli yokulungisa kabusha kumasistimu okuvuselela amandla).

Ingxenye Yesifunda Eyinhloko

• Izingxenye ezibalulekile zihlanganisa:

  • Isilungisi: Iguqula i-AC ibe yi-DC.

    • Isilungisi esingalawuleki: Isebenzisa amabhuloho e-diode (ayikho imfuneko yokulandelana kwesigaba).

    • Isilungisi esilawulwayo: Isebenzisa amamojula e-IGBT/IPM anokulawula okuzwela isigaba.

  • Isixhumanisi se-DC:

    • Ama-Electrolytic capacitor (uchungechunge-luxhumeke kumasistimu angu-380V).

    • Ama-resistors okulinganisa amandla kagesi.

    • Ongakukhetharegeneration resistor(kumasistimu angavuseleli ukuze ahlakaze amandla amaningi).

  • I-Inverter: Iguqula i-DC ibuyele ku-variable-frequency AC yenjini.

    • Izigaba zokuphumayo (U, V, W) zidlula ku-DC-CTs ukuze uthole impendulo yamanje.

Isigaba Sokuphumayo

• Iqala kokuphumayo kwe-inverter.

• Idlula kuma-DC-CTs kanye nezingxenye ze-EMC ozikhethela zona (ama-reactor).

• Ixhuma kumatheminali ezimoto.

Amanothi Abalulekile:

• I-polarity: Qinisekisa ukuxhumeka okulungile kuka-"P" (positive) kanye no-"N" (negative) kuma-capacitor.

• SNUBBER Circuits: Kufakwe kumamojula e-IGBT/IPM ukucindezela ama-voltage spikes ngesikhathi sokushintsha.

• Lawula Amasignali: Amasiginali we-PWM asakazwa ngezintambo ezisontekile ukuze kuncishiswe ukuphazamiseka.

Umfanekiso 1-1: Umjikelezo Oyinhloko Wokulungisa Ongalawulwa

2 Izinyathelo Ezijwayelekile Zokuxazulula Inkinga

2.1 Izimiso Zokuxilonga Iphutha Lesekethe ye-MC

1. I-Symmetry Check:

   • Qinisekisa ukuthi zonke izigaba ezintathu zinemingcele efanayo kagesi (ukumelana, inductance, capacitance).

   • Noma yikuphi ukungalingani kubonisa iphutha (isb, i-diode eyonakele kusilungisi).

2. Ukulandelana Kwesigaba:

   • Landela imidwebo yezintambo ngokuqinile.

   • Qinisekisa ukuthi ukutholwa kwesigaba sokulawula kuhambisana nesekhethi eyinhloko.

2.2 Ukuvula i-Closed-Loop Control

Ukuhlukanisa amaphutha kumasistimu avaliwe:

1. Nqamula I-Traction Motor:

   • Uma uhlelo lusebenza ngokujwayelekile ngaphandle kwenjini, iphutha lisenjini noma izintambo.

   • Uma kungenjalo, gxila kukhabhinethi yokulawula (inverter/rectifier).

2. Gada Izenzo Zothintana naye:

   • Okwamasistimu avuselelayo:

     • Uma#5(oxhumana naye okokufaka) uhambo ngaphambili#LB(i-brake contactor) iyabandakanyeka, hlola isilungisisi.

     • Uma#LBiyabandakanyeka kodwa izinkinga ziyaqhubeka, hlola i-inverter.

2.3 Ukuhlaziywa Kwekhodi Yephutha

• P1 Amakhodi Ebhodi:

  • Isb.,E02(i-overcurrent),E5(DC link overvoltage).

  • Sula amaphutha omlando ngemva kokuhlolwa ngakunye ukuze uthole ukuxilongwa okunembile.

• Amakhodi Wesistimu Yokuvuselela:

  • Hlola ukuqondanisa kwesigaba phakathi kwegridi yegridi kanye nokufakwayo kwamanje.

2.4 (M) Amaphutha emodi ye-ELD

• Izimpawu: Ukuma kungazelelwe ngesikhathi sokusebenza okunamandla ebhethri.

• Imbangela:

  • Idatha yesisindo somthwalo engalungile.

  • Ukuchezuka kwesivinini kuphazamisa ibhalansi kagesi.

• Hlola:

  • Qinisekisa izenzo ze-contactor kanye ne-voltage ephumayo.

  • Gada amakhodi ebhodi le-P1 ngaphambi kokuvalwa kwe-(M)ELD.

  2. Ukungalungiswa kahle kwamabhuleki (igebe: 0.2–0.5mm).

  3. Ibhodi le-E1 elingalungile noma imojuli ye-IGBT.

  4. I-Motor winding short-circuit.

  5. I-transformer yamanje enephutha.
