夏季到了,由于夏季的风雨天多、雷电活动比较剧烈、气温较高,使得电气设备发生事故以至引起火灾的危险增加。许多工厂中都使用着一定数量的电气设备,夏季是电气火灾容易发生的季节。电气火灾是指由于电气方面原因形成火源而引起的火灾。通常是因发热、短路或接地、绝缘破坏以及开关切断电流产生电弧等将电气设备周围的易燃物及电气设备本身引燃而发生火灾。发生电气火灾,首先要有可燃物和助燃环境,其 Summer is coming. Due to the heavy rainy days in summer, the thunder and lightning activity is rather violent and the air temperature is higher, which increases the risk of electric equipment accidents and fires. Many factories use a certain amount of electrical equipment, and summer is a season in which electrical fires can easily occur. Electrical fire refers to the fire caused by the formation of a fire source due to electrical reasons. Fire is usually caused by ignition of flammable substances and electrical equipment themselves around the electrical equipment due to heating, short circuit or grounding, insulation breakdown, and arc generation by switching off current.
