Definition of high-power electrical appliances: the current increases, the wire heats up, and the greater the load, the faster the heating. High-power electrical appliances can easily lead to wire overload, resulting in increased current and wire heating. The greater the load, the faster the heating. The allowable temperature of wire insulation is generally 60℃. If the line is overloaded for a long time, the heating value of the line will increase, which will lead to accelerated aging of the insulation layer. When the temperature is higher than 250℃, the insulation layer will spontaneously ignite and separate from the wire, resulting in short circuit and fire accident. The power supply line of student dormitory is wire instead of cable, and the distribution facilities are configured according to the Ming design, so it is objectively not allowed to use high-power electrical appliances.

Dormitories belong to public areas, and schools have the right to search. "When entering the school, the school expressly stipulated that the power of electrical appliances should not exceed 800 watts." The use of high-power electrical appliances may lead to tripping, which has great hidden dangers. 20 1 1 a college in Yongchuan caused a fire because students used illegal electrical appliances, which led to the burning of the dormitory, and no one around was spared. At this time, the counselor has repeatedly applied to prohibit the use of illegal electrical appliances-refrigerators, electric woks, induction cookers, rice cookers, electric kettles and other high-power electrical appliances. Once found, in addition to confiscation, students' quality credits will be deducted. If the quality credits are not up to standard, you will not be able to obtain graduation certificates and degree certificates.
