MOTOR (FAZ) KORUMA ve FAZ SIRASI RÖLELERÝ MKC-03A, MKC-03L, MKC-04A Genel Sanayi tesislerimizde yaygn olarak kullanlan elektrik motorlarnn iki faza kalarak aþr snmas ve yanmas skça karþlaþlan arza kaynaklarndan biridir. Motor korumasnda skça kullanlan termikmanyetik röle gerek elektro-mekanik yaps, gerekse demeraj akmnn karþlanabilmesi için akm ayarnn yüksek tutulmas nedeniyle, koruma iþleminde yetersiz kalmaktadr. Bu olumsuz etkileri ortadan kaldracak þekilde tasarlanmþ olan nötrlü MKC 03A ve nötrsüz MKC-04A Motor Koruma Röleleri aþa¤daki koruma fonksiyonlarn yerine getirir.

Özel istek üzerine %5-%15 arasý sabit gerilim dengesizliðine sahip cihazlar üretilebilir. Üç fazlý sistemlerde gerilim dengesizliði (asimetri); Yüklerin fazlara dengesiz baðlanmasý sonucu oluþabileceði gibi, Üç fazlý motorlarda fazlardan birinin kesilmesi durumunda da oluþur. Bu durumda kesilen faza ait motor sargý ucunda, motorun diðer sargýlarý üzerinden indüklenerek dönen gerilim görülür. Bu gerilim deðeri motorun cinsine ve yük durumuna göre deðiþir.

A4946 / Rev.2 PHASE FAILURE and PHASE SEQUENCE DEVICES MKC-03A, MKC-03L, MKC-04A Connection Diagrams PK-25 General One of the common faults faced in industrial plants is over-heating and burning of 3 phase motors due to the phase failure. Thermic-magnetic device which is an essential element in motor protection is generally too slow due to both its electromechanical structure and the use of high current setting range to assure demarrage without tripping. Being designed to eliminate the above disadvantages, MKC-03A (with neutral connection ), MKC-04A (without neutral connection) Phase Failure Devices react within 0.2 seconds (fixed) against the following faults and take the motor out of service. (0.5 A, 125 V AC) NC C NO 1 2 3 A1 1 2 3 T1 MKC-04A Stop MKC-03L C1 Start 1. Voltage Unbalance (Not Adjustable) MK-04 includes no neutral connection. When the neutral-phase voltage unbalance is greater than 40% (fixed), the output relay is activated and switched OFF the motor. Devices that have fixed voltage unbalance between 5%-15% can be producted for special order. Unbalanced voltage may occured when; The mains are loaded with unbalanced distribution, One of the 3-phase of motor has lost. In this case, some amount of voltage which produced by other phases will be inducted on the lost phase. Amount of this value depends on both the motor type and amount of load. Output relay is activated when a phase has lost or an unbalanced phase-neutral value, which is occured with any reason, is smaller than the Asymetrical value which is defined for the device. If this unbalanced voltage exceeds the adjusted Asymetrical value, output will release itself and motor will be Switched-off. In Applications; a proper device must be used regarding to the inducted voltage value in two-phase which are remained after the other one has lost.
