| Abstract |
Inside the distribution panel, various power devices such as transformers, VCB, and OCR are installed. The internal temperature under normal operation is approximately 40°C, and when it exceeds this temperature, the air is discharged to the outside by the ventilation fan to maintain a constant temperature. The insulating wire for wiring mainly used inside the distribution panel is HIV or KIV, and most of the insulating materials are PVC Compound, and to ensure flexibility, a thermal stabilizer and an antioxidant are mixed and used to prevent PVC from being decomposed by plasticizer and heat. The softening temperature of PVC is 65~80°C and the ignition temperature is 454°C. However, when a partial discharge occurs in a region inside the distribution panel, heat is generated at that point. When partial discharge occurs continuously, the temperature continues to rise, and the additives are gradually volatilized into gas in the insulating material from usually 100°C, thereby increasing in a large amount as the temperature increases. At this time, the gas smell, "burnt smell(phthalate and carboxylate series gas smell)", can be seen as the beginning of the deterioration phenomenon. A "fire prevention management system" was developed to prevent the occurrence of a fire in advance by detecting gas generated in such a deterioration phenomenon and determining it as a fire sign.
By applying the developed system to the distribution panel, it is expected that it will not only reduce human and material damage, but also be able to cope with disaster safety accidents in advance when operating as an unmanned system. |
