This paper reproduces the possibility of accidents and electric fires in the magnetic contactor(MC) of the control panel installed for the temperature control of the freezing warehouse, the low temperature warehouse and the storage. In addition, I would like to present a method for analyzing the characteristics and causes of accidents that occur due to an under voltage applied to a MC or an abnormal operation due to a foreign substance being interrupted. The inside of the control panel is composed of a molded-case circuit breaker(MCCB), a magnetic contactor(MC), a timer, and a terminal board. The MC for compressor and the MC for compressor control are designed to operate sequentially. The deterioration of the MC is caused by undervoltage and overvoltage, physical shock or vibration, inflow of foreign substances such as cockroaches and insects, formation of water or moisture. In other words, the inflow of foreign matter breaks the balance of the electromagnetic field of the MC and interferes with the formation of the magnetic path, so that heat and vibration are continuously generated and the function of the contact point is deteriorated. Therefore, in this paper, we analyze the ignition mechanism of MC and use it as fire detection data for the control panel for the refrigeration warehouse.
