ABB Vacuum Contactor KC2 Power Supply System Technical Transformation Plan Aikace ABB Vacuum Contactor KC2 Power Supply System Technical Transformation Plan

Gwandar Aiki​
Sistem na ɗaya daga ƙungiyar ake yi a cikin 10kV air compressor ta amfani da ABB vacuum contactor KC2 a matsayin yanayi na kontrola wajen shirye-shirye. Yanayi na wide-voltage power supply module da ke gudanar da wannan contactor ta samu masu hanyar:

1. ​Maimaito mai kadan-kadan: Yanayin power supply ba a iya yin rawa aiki daga 300V zuwa 12V, wanda ya haɗa a zama tashin fuse.
2. ​Koyarwa mai kadan-kadan: Yadda ake gudanar da yanayi a wurare ba a tabbas ba, wanda ya haɗa a zama tashin koyarwa, wanda ya ɗauki shekaru kan abubuwan da suka ɗauki.
3. ​Al'adu mai kadan-kadan: Yanayin orijinal ta zaɓe kusan 5,000 RMB, wanda ya haɗa a zama al'adu mai kadan-kadan na ilimi.

​II. WONE Technical Transformation Plan​
​Tsarin Aiki: Amfani da "functional decomposition" strategy don in karfi aiki na pull-in da holding, dukana ake jin da yanayi daban-daban.

​Sistemin Kalmomin:

1. ​Yanayin power supply orijinal: Yana da aiki mai sauƙi kawai, ake jin da shi 300V DC don kawo contactor zuwa pull-in.
2. ​Yanayin power supply 12V mai tsari: Yana da aiki na holding mai tsari, ake bayyana maintaining current zuwa coil na contactor bayan pull-in.
3. ​Control relay: Yana ɗaukar aiki na automatic control wajen kawo neman yanayi bayan an samu pull-in.
4. ​Isolation diode: Yana ɗaukar aiki na kawo neman interference daga yanayi daban-daban.

​Prinsipin Aiki:

• A lokacin da ake fara, yanayin orijinal ta jin da shi 300V DC don kawo contactor zuwa pull-in.
• Bayan an samu pull-in, auxiliary contact ta ɗauka control relay.
• A lokacin da control relay ta ɗauka, ta kawo neman yanayin power supply na orijinal da kuma ta kawo neman 12V holding power supply.
• Yanayin 12V power supply ta bayyana maintaining current zuwa coil na contactor, don a yi aiki na ɗaya.

​III. Implementation Plan​
​Jikin Aiki:

​Requirements na Installation:

1. Yanayin 12V power supply module zai iya a gudanar da ita a wurare da koyarwa mai kyau a waje.
2. Duk wiring zai iya taimaka da electrical installation standards.
3. Abubuwan da ake ɗauki zai iya a gudanar da su da brackets don a ɗaukan aiki.

​IV. Advantages of the Plan​

1. ​Cost-effectiveness: Al'adun transformation ta zaɓe kusan 160 RMB, mafi girma da 5,000 RMB na yanayin orijinal.
2. ​Reliability:
• Aikin yanayin orijinal ta ƙarin zuwa instantaneous, wanda ya haɗa a zama tafara.
• Yanayin 12V power supply module ta fi sani da industrial component, mafi girma da ake sauransu da ake ɗauki.
3. ​Maintainability: Yanayin da ake ɗauki ta gudanar da ita a wurare da koyarwa mai kyau, wanda ya haɗa a zama aiki na ɗaya da kusa.
4. ​Safety: Electrical isolation ta ɗaukar aiki na safe system operation.
5. ​Proven effectiveness: Duk da cewa transformations daban-daban sun yi aiki a tafara na shekaru biyu, da tushen mai yawa.

​V. Implementation Results​
Wannan plan ta ƙarfin da suka gyara original design flaws through technical innovation, ta samun:

• Percentage na equipment failure ta ci ɗaya da 90%.
• Annual maintenance costs ta ci ɗaya da 80%.
• Equipment availability ta ci ɗaya zuwa 99.5%.
• Maintenance response time ta ci ɗaya zuwa hours.
