Why can't university dormitories use high-power appliances?

For safety and cost reasons, high-power electrical appliances are not allowed in university dormitories. Universities generally have old campuses and new campuses. The old campus was built for a long time, and the industry was underdeveloped at the time of construction. At that time, there were no high-power appliances. Therefore, the rated current of air switches, fuses and wires in the distribution room is too small to withstand the use of high-power electrical appliances. And because of the age, the wires are aging. If high-power electrical appliances are used, the electric energy on the wires will be converted into heat energy, which will lead to serious heating of the wires. If the temperature of the wire exceeds its heat-resistant temperature, it will lead to the melting of the surface plastic, which will lead to the contact between the live wire and the neutral wire, thus causing a short circuit, which will lead to the burning of the whole line and even a serious fire. Therefore, the old campus prohibits the use of high-power electrical appliances.

The new campus of the university has not been built for a long time, but there are many laboratories, teaching equipment, air compressors, exhaust fans and other high-power and power-consuming equipment in the university, and the rated current on the school bus is certain. In order not to affect the use of these high-power equipment, the electricity consumption in the dormitory will be reduced, resulting in the inability to use high-power equipment in the dormitory. In addition, considering the cost, if the dormitory uses high-power electrical appliances, it must use thicker wires, which will increase the cost.

There are many people in university dormitories, the quality of high-power electrical appliances is uneven, the use of students is not standardized, and the turnover of personnel is large, which is easy to cause accidents due to misoperation. Once an accident occurs due to leakage or improper use, it will lead to personal danger. If not handled in time, it may also lead to a series of accidents, which are losses to students, families and schools.

It can be said that college students go to school to learn knowledge. The school has a canteen and a bathroom, which provides us with a convenient learning and living environment. There is no need to use high-power appliances in the dormitory. If you want to use it for yourself, you can rent out the house, which is convenient for you and does not violate the dormitory regulations.
