家用电器起火燃烧,一般有五种诱因: 一、电线负荷过大。一般来说家庭照明用电的电线较细,负载能力低。但随着家用电器设备的增加,电线的负载能力不断递增、容易使电线剧烈发热,绝缘损坏,从而造成相间或对地短路电流起火。 Household appliances fire burning, there are five general incentives: First, the electrical load is too large. In general, household lighting electricity wire thinner, low load capacity. However, with the increase of household electrical appliances, the load capacity of the electric wire is continuously increasing, which makes it easy to cause the electric wire to generate intense heat and insulation damage, thereby causing the short-circuit current between phases or on the fire.
