Analysis and prevention of electrical fires

Electrical fires are mainly induced by electrical failure,and it causes great loss to social production and people＇s life safety.In this paper,the process,causes and characteristics of electrical fire were analyzed,and the hazard of electrical fire was pointed out.The importance of attaching importance to prevention work of electrical fire was illustrated,and the countermeasures of electrical fire prevention were put forward,such as establishing and improving the organization and institution,conducting the popularization and training of electric fire prevention knowledge correctly selecting electrical facilities,enhancing the supervision and management of electrical products and engineering quality,cleaning the energized electrical equipment places,strengthening the fire prevention of low voltage line,reinforcing the prevention of lightning fires,carrying out the fire precaution induced by higher harmonic,completing the electrical fire pr ecaution of small resistance grounding system in 10KV power grid,and establishing the automatic monitoring and warning system and network of electrical fire.It will play a very active role in guiding the electrical fire prevention and restraining the occurrence of electrical fire.
