建筑内部装修都不同程度地采用了大量可燃、易燃装修材料,从而使火灾危险性大大增加,引发的火灾事故逐年上升。其中,电气火灾所占比例相当大,预防电气火灾已成为消防监督工作的当务之急。内部装修的电气火灾危险性1.导线截面选择不当。随意接入电气设备或设计时没有充分考虑日后发展需要,线截面所留裕度过小,导致配电线路过载。电气设备或导线的功率超过其额定值,会引起导线过热,截流导体 The interior decoration has adopted a large amount of combustible and flammable decoration materials to varying extents, so that the fire risk is greatly increased, and the fire accidents caused by them are increasing year by year. Among them, the proportion of electrical fires is quite large. Preventing electric fire has become a priority of fire supervision. Electrical fire hazard for interior decoration 1. Improper wire cross-section selection. Random access to electrical equipment or design did not fully consider the needs of future development, the line cross-section left margin is too small, resulting in distribution lines overload. Electrical equipment or wires that exceed their rating will cause the wire to overheat and shut off the conductor
