近年来,家电及厨房电气化的用电器具不断增多,增大了生活用电量,同时也增加了电气事故的机率。无论是原有民宅用电线路或新建民宅用电线路,皆会因用电量增加,而电流亦增大,故有一个与其导线截面相对应的问题。否则将会按电流的热效应规律(φ=0.24I~2Rt卡)发热,造成多余热量不宜散发。
In recent years, appliances and kitchen electrification of electrical appliances continue to increase, increasing the amount of electricity consumption, but also increase the probability of electrical accidents. Whether it is the original residential electricity lines or new residential electricity lines, both because of increased power consumption, and the current also increases, so there is a problem with its wire cross-section. Otherwise, it will generate heat according to the law of thermal effect of current (φ = 0.24I ~ 2Rt card), resulting in unnecessary heat dissipation.
