Mitsubishi Elevator Power Circuit (PS) Itọsọna Laasigbotitusita

1 Akopọ

Circuit PS (Ipese Agbara) n pese agbara to ṣe pataki si awọn ọna ṣiṣe elevator, tito lẹtọ simora agbara awọn ọna šišeatipajawiri agbara awọn ọna šiše.

Key Power Designations

Awọn akọsilẹ:

• Awọn ipele foliteji le yatọ nipasẹ awoṣe elevator (fun apẹẹrẹ, # 79 ninu yara ẹrọ-yara-kere elevators ibaamu #420 foliteji).

• Nigbagbogbo tọka si awoṣe-kan pato awọn itọnisọna imọ-ẹrọ fun awọn pato pato.

Mora Power Systems

1. Amunawa-Da:

   • Input: 380V AC → Ijade: Pupọ AC / DC voltages nipasẹ awọn windings secondary.

   • Pẹlu awọn atunṣe fun awọn abajade DC (fun apẹẹrẹ, 5V fun awọn igbimọ iṣakoso).

   • Awọn oluyipada afikun le ṣe afikun fun awọn ẹrọ ibalẹ agbara giga tabi ina ailewu.

2. DC-DC Converter-Da:

   • Iṣawọle: 380V AC → DC 48V → Yipada si awọn foliteji DC ti o nilo.

   • Iyatọ bọtini:

     • Awọn ọna ti o gbe wọle ni idaduro agbara AC fun ibalẹ / awọn ibudo oke ọkọ ayọkẹlẹ.

     • Awọn eto inu ile yipada ni kikun si DC.

Awọn ọna agbara pajawiri

• (M)ELD (Ẹrọ ibalẹ pajawiri):

  • Ṣiṣẹ lakoko awọn ijade agbara lati wakọ elevator si ilẹ ti o sunmọ julọ.

  • Awọn oriṣi meji:

    1. Idaduro Muu ṣiṣẹ: Nbeere ìmúdájú ti akoj ikuna; ya sọtọ agbara akoj titi iṣẹ yoo fi pari.

    2. Afẹyinti lẹsẹkẹsẹ: Ntọju DC akero foliteji nigba outages.

Precharge / Dasile iyika

• Išẹ: Lailewu idiyele / itusilẹ DC ọna asopọ capacitors.

• Awọn eroja:

  • Precharge resistors (iye inrush lọwọlọwọ).

  • Awọn resistors itusilẹ (tu agbara ti o ku silẹ lẹhin-tiipa).

• Mimu aṣiṣe: WoMC Circuitapakan fun awọn oran eto atunṣe.

2 Gbogbogbo Laasigbotitusita Igbesẹ

2.1 Mora Power System ašiše

Awọn ọrọ to wọpọ:

1. Fiusi / Circuit Fifọ Tripping:

   • Awọn igbesẹ:

     1. Ge asopọ Circuit ti ko tọ.

     2. Iwọn foliteji ni orisun agbara.

     3. Ṣayẹwo idena idabobo pẹlu megohmmeter (> 5MΩ).

     4. Tun awọn ẹru pọ ni ọkọọkan lati ṣe idanimọ paati aṣiṣe.

2. Foliteji ajeji:

   • Awọn igbesẹ:

     1. Yasọtọ orisun agbara ati iwọn iṣelọpọ.

     2. Fun awọn ayirapada: Ṣatunṣe awọn titẹ titẹ sii ti foliteji ba yapa.

     3. Fun DC-DC converters: Rọpo kuro ti o ba ti foliteji ilana kuna.

3. EMI / Ariwo kikọlu:

   • Idinku:

     • Lọtọ ga / kekere foliteji kebulu.

     • Lo ipa-ọna orthogonal fun awọn ila ti o jọra.

     • Ilẹ USB Trays lati din Ìtọjú.

2.2 Precharge / Dasile Circuit awọn ašiše

Awọn aami aisan:

1. Aiṣedeede Gbigba agbara Foliteji:

   • Ṣayẹwo precharge resistors fun overheating tabi fifun gbona fuses.

   • Wiwọn foliteji ju silẹ kọja awọn paati (fun apẹẹrẹ, resistors, awọn kebulu).

2. Aago gbigba agbara ti o gbooro sii:

   • Ṣayẹwo awọn capacitors, iwọntunwọnsi resistors, ati itusilẹ awọn ipa ọna (fun apẹẹrẹ, awọn module rectifier, busbars).

Awọn Igbesẹ Aisan:

1. Ge asopọ gbogbo awọn asopọ DCP (DC Rere).

2. Wiwọn precharge Circuit o wu.

3. Tun awọn iyika DCP pọ ni afikun lati wa awọn ọna itusilẹ ajeji.

2.3 (M) ELD System Aṣiṣe

Awọn ọrọ to wọpọ:

1. (M)ELD kuna lati Bẹrẹ:

   • Ṣe idaniloju ifihan agbara #79 lakoko ikuna akoj.

   • Ṣayẹwo foliteji batiri ati awọn asopọ.

   • Ṣayẹwo gbogbo awọn iyipada iṣakoso (esp. ni ẹrọ-yara-kere setups).

2. Aiṣedeede (M) ELD Foliteji:

   • Ṣe idanwo ilera batiri ati awọn iyika gbigba agbara.

   • Fun awọn ọna ṣiṣe pẹlu awọn Ayirapada igbelaruge: Daju awọn titẹ titẹ sii/jade awọn titẹ foliteji.

3. Tiipa airotẹlẹ:

   • Ṣayẹwo awọn isunmọ aabo (fun apẹẹrẹ, #89) ati awọn ifihan agbara agbegbe ilẹkun.

3 Awọn aṣiṣe ti o wọpọ & Awọn ojutu

3.1 Awọn aiṣedeede Foliteji (C10/C20, H10/H20, S79/S420)

3.2 Iṣakoso Board Ikuna lati Power On

3.3 Amunawa bibajẹ

3.4 (M) ElD aiṣedeede

3.5 Precharge / Dasile Circuit oran

Awọn akọsilẹ iwe:
Itọsọna yii ṣe deede pẹlu awọn iṣedede elevator Mitsubishi. Tẹle awọn ilana aabo nigbagbogbo ki o kan si awọn ilana imọ-ẹrọ fun awọn alaye awoṣe-kan pato.
