هیچ رێگایەک هەیە بۆ گرتنی دەرەخستنی موتوری ناڕێکخراوی سێ فاز؟
Hemî divê bikar bînin da ku dûrê ya du terminal ê biguherînin an hêza phase sequence biguherînin, yana metodên din derbasdar da ku bi taybetmendiyeyek digirek jî hêza motorê induksyonî three-phase biguherîne. Heke ti metodên bêtir yên bikar bînin:
1. Bi Karberdanan Phase Sequence Relay
Principle: Phase sequence relay dikare hêza phase sequence ya three-phase power supply bideşînin û otomatîkî li ser logic-a predifined biguhere.
Application: Yekîtiyek ji bo vebijarkên ku hewceya otomatîkî guherandina direction ya motor heye, wêjî hemî sisteman control automated.
Operation: Phase sequence relay install bike û logic-a detection û switching setup bike. Heta ku hewceya guhertina direction ya motor be, relay otomatîkî hêza phase sequence biguhere.
2. Bi Karberdanan Programmable Logic Controller (PLC)
Principle: PLC dikare hêza phase sequence ya motor bi programming kontrol bike, lêkîn hêza rotation ya motor biguhere.
Application: Yekîtiyek ji bo sisteman automation complex ke dikarin hêzan control functions zorav bike.
Operation: PLC program bike bi karberdan relays output hêza phase sequence ya motor kontrol bike.
3. Bi Karberdanan Variable Frequency Drive (VFD)
Principle: VFD nînimetan dikare speed ya motor regulate bike lê dikare hêza rotation ya motor bi settings software biguhere.
Application: Bistîna wekî ji bo vebijarkên ku regulation speed û change direction hewce ne, wêjî industrial automation û elevator systems.
Operation: Hêza rotation ya motor bi panel control ya VFD û signals input external set bike.
4. Bi Karberdanan Reversing Contactor
Principle: Reversing contactor ji du contactors gerdaye, yek ji bo forward operation û yek ji bo reverse operation. Bi kontrolkirina switching-yê ya du contactors ê, hêza rotation ya motor biguhere.
Application: Yekîtiyek ji bo vebijarkên ku manual û automatic switching direction ya motor hewce ne.
Operation: Du contactors connect bike û states-yan switch bike bi circuit control hêza phase sequence ya motor biguhere.
5. Bi Karberdanan Electronic Commutation Module
Principle: Electronic commutation module hêza phase sequence ya motor bi electronic circuits kontrol bike, lêkîn hêza rotation ya motor biguhere.
Application: Yekîtiyek ji bo vebijarkên ku precision high û fast response hewce ne, wêjî equipment control precision.
Operation: Electronic commutation module install bike û switching phase sequence bi signals external û logic built-in kontrol bike.
6. Bi Karberdanan Soft Starter
Principle: Soft starter dikare hêza phase sequence ya motor li ser dema starting process smoothly biguhere, lêkîn hêza rotation ya motor biguhere.
Application: Yekîtiyek ji bo vebijarkên ku smooth starting û change direction hewce ne, wêjî machinery large.
Operation: Hêza rotation ya motor bi panel control ya soft starter û signals external set bike.
7. Bi Karberdanan Switch Manual
Principle: Switch manual dikare hêza phase sequence ya motor biguhere, lêkîn hêza rotation ya motor biguhere.
Application: Yekîtiyek ji bo vebijarkên simple ku frequent changes direction hewce ne.
Operation: Switch manual operate bike hêza phase sequence ya motor biguhere.
Summary
Hêza motor induction three-phase dikare bi metodên din digirek biguhere, including phase sequence relays, programmable logic controllers (PLCs), variable frequency drives (VFDs), reversing contactors, electronic commutation modules, soft starters, û switches manual. Choice of method divê li ser specific application requirements, system complexity, û cost factors base bike.
