Abstract :
ABSTRACT Muna, Ahmad Chirzul, 2023, 551811216635 T ?Analysis of Magnetic Contactor Burning at the Starter Panel Provision Refrigeration Plant on MT. Pelagos One?, Thesis of Technical Department,Diploma IV Program, Semarang Merchant Marine Polytechnic, Supervisor I: Dr. Darul Prayogo, M.Pd, Supervisor II: M. Sapta Heriyawan, S.Kom, M.Si. A magnetic contactor is an electrical device that operates on the principle of electromagnetic induction in a copper coil or coil that is energized, creating a magnetic field that closes the NO (Normally Open) auxiliary contact and opens the NC (Normally Close) auxiliary contact. The magnetic contactor is a control on the provision refrigeration plant auxiliary machinery, and it is known that there is a trip on the control panel box, which causes the operation of the refrigeration compressor to stop; after checking, there is damage to the electrical component, namely a burning magnetic contactor. The goal of this research is to determine the causes of magnetic contactor burning, the impact of magnetic contactor burning, and the methods used to overcome the problem of burning magnetic contactors in MT. Pelagos One. The author employs a descriptive qualitative research method in the preparation of this thesis, employing the SHELL approach (Software, Hardware, Environment, and Liveware) to facilitate data analysis techniques. The author collects data through observation, interviews, and documentation studies that are carried out directly on the research objects in MT. Pelagos One. The magnetic contactor was examined, and interviews with the Chief Engineer and Electrician were conducted. The engine room provided documentation in the form of manual books, magnetic contactor data sheets, photos of magnetic contactor problems, maintenance records, and electrical component repairs. According to the findings of this study, the factors that cause burning or damage to the magnetic contactor are inaccuracy when checking and maintaining, disturbances that occur include uneven moving contact mounts on the contactor and contactors that have been eaten away by age due to use. As a result, the contactor does not work optimally, there is an increase in current, and the contactor coil burns. Periodic maintenance and repair of magnetic contactors and other electrical components every 6 month period, including replacement with new contactor parts, to prevent damage from spreading to other components.
