随着电力建设的飞速发展,特别是在国家“两改一同价”工作逐步实施以后,电能更加丰富,电价更加优惠。电烤炉因方便、快捷、无污染而逐渐步入了工厂、商店、办公室和家庭,由于电烤炉比较危险,加之使用、维护、管理不当,由此引发的火灾事故日益增多,造成的损失也越来越大。因此,弄清电烤炉引发火灾的本质,掌握各种有效的预防方法,对保护人民生命安全和国家财产不受损失是大有裨益的。电烤炉引发火灾的主要原因是:(1)电烤炉正常工作时,电阻丝的工作温度可达700-1100°C,由于温度高,很容易引燃误落或飞溅到电阻丝上的可燃物,从而引发火灾。(2)电烤炉一般没有定温、定时的保护装置,使用时安放的位置不恰当,容易引燃附近的可燃物或烘烤物,引起着火。(3)电烤炉功率较大,通过电烤炉连接线的电流也较大,如果有导线接触不良,绝缘损坏,插头松
With the rapid development of power construction, especially after the gradual implementation of the national “two changes and one price sharing” work, the electricity will be more abundant and the electricity price will be more favorable. Due to the convenience, speed and pollution-free operation, electric ovens gradually entered factories, shops, offices and homes. As the electric ovens are dangerous and their use, maintenance and management are not properly controlled, the fire accidents caused by them are increasing day by day, resulting in losses Also growing. Therefore, to understand the nature of electric fires and to master various effective prevention methods is of great benefit to the protection of people’s lives and the loss of state property. The main reason that the electric oven causes fire is: (1) When the electric oven is working normally, the working temperature of the electric resistance wire can reach 700-1100 ° C. Because of the high temperature, it is easy to ignite or fall onto the resistance wire Flammable, causing a fire. (2) Electric ovens generally do not have constant temperature, time protection device, the use of improper placement of location, easy to ignite nearby combustibles or baked goods, causing fire. (3) larger electric oven, through the electric oven cable current is larger, if there is poor wire contact, insulation damage, plugs loose
