1 Mwachidule

Dera la PS (Power Supply) limapereka mphamvu yofunikira ku ma elevator subsystems, omwe ali m'magulumachitidwe ochiritsira mphamvundimachitidwe amphamvu adzidzidzi.

Mauthenga Ofunika Kwambiri

Dzina la Mphamvu	Voteji	Kugwiritsa ntchito
#79	Nthawi zambiri AC 110V	Imayendetsa zolumikizira zazikulu, mabwalo achitetezo, maloko a zitseko, ndi machitidwe amabuleki.
#420	AC 24–48V	Amapereka ma siwiwiti othandizira (mwachitsanzo, masiwichi owongolera, ma switch ochepera, ma relay).
C10-C00-C20	AC 100 V	Imalimbitsa zida zamagalimoto (mwachitsanzo, pokwerera magalimoto, gulu la opareshoni).
H10-H20	AC 100 V	Imapereka zida zoyatsira (zosinthidwa kukhala DC kudzera pa mabokosi amagetsi kuti agwiritse ntchito magetsi otsika).
L10-L20	AC 220V	Zozungulira zowunikira.
B200-B00	Zimasiyana	Zida zapadera (mwachitsanzo, ma braking system).

Zolemba:

Magetsi amagetsi amatha kusiyanasiyana malinga ndi ma elevator (mwachitsanzo, #79 mu zikepe zocheperako pamakina zimafanana ndi #420 voteji).
Nthawi zonse tchulani zolemba zaukadaulo zachitsanzo kuti mudziwe zenizeni.

Makina Okhazikika Amagetsi

Transformer-Based:
- Zolowetsa: 380V AC → Zotulutsa: Ma volts angapo a AC/DC kudzera pamamphepo achiwiri.
- Mulinso zosinthira pazotulutsa za DC (mwachitsanzo, 5V yama board owongolera).
- Ma transformer owonjezera atha kuwonjezeredwa pazida zoyatsira zamphamvu kwambiri kapena kuyatsa kwachitetezo.
DC-DC Converter-Based:
- Zolowetsa: 380V AC → DC 48V → Zotembenuzidwira kumagetsi ofunikira a DC.
- Kusiyana Kwakukulu:
  - Makina obwera kuchokera kunja amakhala ndi mphamvu ya AC pakutera/masiteshoni apamwamba amagalimoto.
  - Machitidwe apakhomo amasintha kwathunthu kukhala DC.

Emergency Power Systems

(M)ELD (Chida Cholowera Mwadzidzidzi):
- Imayatsa nthawi yazimitsidwa yamagetsi kuti muyendetse chikepe kupita kumalo oyandikana nawo.
- Mitundu iwiri:
  1. Kuchedwetsa Kutsegula: Imafunikira chitsimikiziro cha kulephera kwa gridi; imalekanitsa mphamvu ya grid mpaka ntchito itamaliza.
  2. Instant Backup: Imasunga ma voliyumu amabasi a DC nthawi yazimitsa.

Mayendedwe a Precharge / Discharge

Ntchito: Malizitsani / tulutsani ma capacitor olumikizirana a DC.
Zigawo:
- Precharge resistors (malire inrush current).
- Zotsutsa zotulutsa (kutayani mphamvu zotsalira pambuyo pozimitsa).
Kusamalira Zolakwa: OnaniMC Circuitgawo la nkhani za regenerative system.

Precharge Circuit

Precharge Circuit Schematic

2 Njira Zothetsera Mavuto Onse

2.1 Zowonongeka Zowonongeka Zamagetsi

Mavuto Ambiri:

Fuse / Circuit Breaker Tripping:
- Masitepe:
  1. Chotsani dera lolakwika.
  2. Yezerani voteji pa gwero la mphamvu.
  3. Yang'anani kukana kwa insulation ndi megohmmeter (> 5MΩ).
  4. Lumikizaninso katundu mmodzimmodzi kuti azindikire chigawo cholakwika.
Mphamvu yamagetsi yamagetsi:
- Masitepe:
  1. Patulani gwero la mphamvu ndi kuyeza kutulutsa.
  2. Kwa ma transformer: Sinthani ma taps olowera ngati magetsi apatuka.
  3. Kwa otembenuza a DC-DC: Bwezerani chigawocho ngati malamulo a magetsi alephera.
Kusokoneza kwa EMI/Noise:
- Kuchepetsa:
  - Siyanitsani zingwe zamphamvu kwambiri/zotsika.
  - Gwiritsani ntchito orthogonal routing pamizere yofananira.
  - Ma tray apansi ochepetsera ma radiation.

2.2 Precharge / Discharge Circuit Zolakwika

Zizindikiro:

Mphamvu yamagetsi yamagetsi yamagetsi:
- Yang'anani ma resistor precharge for Heatther kapena kuwombedwa kwa fuse zamafuta.
- Yezerani kutsika kwamagetsi pazigawo zonse (monga zopinga, zingwe).
Nthawi Yowonjezera Yolipiritsa:
- Yang'anani ma capacitor, ma bancing resistors, ndi njira zotulutsira (monga ma module okonzanso, mabasi).

Njira Zowunika:

Lumikizani malumikizidwe onse a DCP (DC Positive).
Yesani precharge dera linanena bungwe.
Lumikizaninso mabwalo a DCP mochulukira kuti mupeze njira zotulutsira zosakhazikika.

2.3 (M)ELD System Zolakwika

Mavuto Ambiri:

(M)ELD Yalephera Kuyamba:
- Tsimikizirani #79 chizindikiro champhamvu panthawi yakulephera kwa gridi.
- Onani mphamvu ya batri ndi maulumikizidwe.
- Yang'anani masiwichi onse owongolera (esp. m'makonzedwe opanda zipinda zochepera makina).
Mphamvu yamagetsi yamagetsi (M)ELD:
- Yesani thanzi la batri ndi mabwalo opangira.
- Kwa makina okhala ndi ma boost transfoma: Tsimikizirani ma tap olowetsa/kutulutsa mphamvu.
Kuyimitsa Mosayembekezeka:
- Yang'anani ma relay otetezedwa (mwachitsanzo, #89) ndi ma siginecha a zitseko.

3 Zolakwika Zofala & Mayankho

3.5 Kulipira Kwambiri / Kutulutsa Nkhani Zozungulira

Chifukwa	Yankho
Lowetsani Mphamvu Yamphamvu	Konzani voteji ya gridi kapena sinthani gawo lamagetsi.
Kulephera Kwagawo	Yesani ndikusintha mbali zolakwika (resistors, capacitors, mabasi).

Zolemba Zolemba:
Bukuli likugwirizana ndi miyezo ya Mitsubishi elevator. Nthawi zonse tsatirani ndondomeko zachitetezo ndikuyang'ana zolemba zaukadaulo kuti mumve zambiri zachitsanzo.
