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

1 Mwachidule

Dera la MC lili ndi magawo atatu:gawo lolowetsa,gawo lalikulu la dera,ndigawo lotulutsa.

Gawo Lolowetsa

• Imayambira pazolowera magetsi.

• AmadutsaZithunzi za EMC(zosefera, zoyatsira).

• Imalumikizana ndi gawo la inverter kudzera pa control contactor#5(kapena rectifier module mumachitidwe okonzanso mphamvu).

Gawo Lalikulu Lozungulira

• Zofunika kwambiri zikuphatikizapo:

  • Wokonzanso: Amasintha AC kukhala DC.

    • Wowongolera Wosawongolera: Amagwiritsa ntchito milatho ya diode (palibe gawo lotsatizana).

    • Controlled Rectifier: Amagwiritsa ntchito ma module a IGBT/IPM okhala ndi gawo lomvera.

  • DC Link:

    • Electrolytic capacitors (mndandanda-olumikizidwa ndi machitidwe a 380V).

    • Magetsi oletsa magetsi.

    • Zosankharegeneration resistor(kwa machitidwe osasinthika kuti awononge mphamvu zambiri).

  • Inverter: Imasintha DC kukhala ma frequency frequency AC a injini.

    • Magawo otulutsa (U, V, W) amadutsa ma DC-CTs kuti ayankhe.

Gawo lotulutsa

• Zimayambira kuchokera ku inverter.

• Idutsa ma DC-CTs ndi zigawo zosankhidwa za EMC (ma reactors).

• Amalumikizana ndi ma terminals.

Mfundo zazikuluzikulu:

• Polarity: Onetsetsani kuti zolumikizira "P" (zabwino) ndi "N" (zoipa) zolondola za ma capacitor.

• Madera a SNUBBER: Anayika pa IGBT/IPM modules kupondereza voteji spikes pa kusintha.

• Control Signs: Zizindikiro za PWM zimafalitsidwa kudzera pazingwe zopotoka kuti muchepetse kusokoneza.

Chithunzi 1-1: Dera Lalikulu la Rectifier Losayendetsedwa

2 Njira Zothetsera Mavuto Onse

2.1 Mfundo za MC Circuit Fault Diagnosis

1. Symmetry Check:

   • Tsimikizirani magawo onse atatu ali ndi magawo amagetsi ofanana (kukana, inductance, capacitance).

   • Kusalinganika kulikonse kumasonyeza vuto (mwachitsanzo, diode yowonongeka mu rectifier).

2. Phase Sequence Compliance:

   • Tsatirani zithunzi zamawaya mosamalitsa.

   • Onetsetsani kuti kudziwika kwa gawo lowongolera kumayenderana ndi dera lalikulu.

2.2 Kutsegula Kotseka-Loop Control

Kusiyanitsa zolakwika mu machitidwe otsekedwa:

1. Chotsani Magalimoto Oyendetsa:

   • Ngati dongosolo limagwira ntchito bwino popanda mota, vuto limakhala mu mota kapena zingwe.

   • Ngati sichoncho, yang'anani pa kabati yowongolera (inverter / rectifier).

2. Yang'anirani Zochita za Contactor:

   • Kwa machitidwe osinthika:

     • Ngati#5(lolowetsa contactor) maulendo kale#LB(brake contactor) amachita, fufuzani wokonzanso.

     • Ngati#LBzimagwira koma zovuta zikupitilira, yang'anani inverter.

2.3 Kusanthula kwa Khodi Yolakwa

• P1 Board kodi:

  • Mwachitsanzo,E02(kuchuluka),E5(DC link overvoltage).

  • Chotsani zolakwa za mbiriyakale pambuyo pa mayesero aliwonse kuti mudziwe zolondola.

• Ma Code Regenerative System:

  • Yang'anani mayanidwe agawo pakati pa grid voltage ndi zolowetsa zapano.

2.4 (M)ELD Mode Zolakwika

• Zizindikiro: Kuyima mwadzidzidzi panthawi yogwiritsira ntchito batire.

• Zomwe Zimayambitsa:

  • Deta yolakwika yoyezera katundu.

  • Kuthamanga kwa liwiro kumasokoneza mphamvu yamagetsi.

• Onani:

  • Tsimikizirani zochita za contactor ndi voteji linanena bungwe.

  • Yang'anirani ma code a board a P1 (M)ELD asanatseke.

2.5 Kuzindikira Zolakwa za Magalimoto

3 Zolakwika Zofala & Mayankho

3.1 Chizindikiro cha PWFH(PP) Kuzimitsa kapena Kuwala

• Zoyambitsa:

  1. Kutayika kwa gawo kapena kutsata kolakwika.

  2. Gulu lowongolera lolakwika (M1, E1, kapena P1).

• Zothetsera:

  • Yezerani voteji ndi dongosolo loyenera la gawo.

  • Bwezerani bolodi yolakwika.

3.2 Maginito Pole Kulephera Kuphunzira

• Zoyambitsa:

  1. Encoder misalignment (gwiritsani ntchito chizindikiro choyimba kuti muwone kukhazikika).

  2. Zingwe za encoder zowonongeka.

  3. Encoder yolakwika kapena bolodi ya P1.

  4. Zokonda zosayenera (mwachitsanzo, masinthidwe amotor traction).

• Zothetsera:

  • Ikaninso encoder, sinthani zingwe/mabodi, kapena sinthani magawo.

3.3 Nthawi zambiri E02 (Overcurrent) Cholakwika

• Zoyambitsa:

  1. Kuzizira kwa module (mafani otsekedwa, phala losafanana lamafuta).

  2. Kusokonezeka kwa Brake (kusiyana: 0.2-0.5mm).

  3. E1 board yolakwika kapena IGBT module.

  4. Kuzungulira mozungulira mozungulira mozungulira.

  5. Chosinthira chamakono cholakwika.

• Zothetsera:

  • Yeretsani mafani, ikaninso phala lotentha, sinthani mabuleki, kapena sinthani zinthu zina.

3.4 Zolakwa Zazikulu Zomwe Zachitika

• Zoyambitsa:

  1. Kusagwirizana kwa mapulogalamu oyendetsa galimoto.

  2. Asymmetric brake kumasulidwa.

  3. Kulephera kwa inshuwaransi yamagalimoto.

• Zothetsera:

  • Sinthani mapulogalamu, kulunzanitsa mabuleki, kapena kusintha ma windings a injini.

Zolemba Zolemba:
Bukuli likugwirizana ndi miyezo yaukadaulo ya Mitsubishi elevator. Nthawi zonse tsatirani ndondomeko zachitetezo ndikuyang'ana m'mabuku ovomerezeka kuti mudziwe zambiri zachitsanzo.
