Blackboard report related information for safe electricity use 1: Information related to safe electricity use

The heat in summer is unbearable, and air conditioners and electric fans are also turning on. Fires and electric shock accidents caused by the use of these electrical appliances occur every year. How to use electricity safely and scientifically is a major issue that every family must pay attention to. First, consider the endurance of the energy meter and low-voltage lines. The electric power that an electric energy meter can withstand is approximately the value of voltage multiplied by current. The voltage of residential electricity is 220 volts. For example, if a 2.5-amp electric energy meter is installed at home, the power it can withstand is 550 watts. A 600-watt rice cooker cannot be used. . Based on this calculation, the electrical power that a 5-A electric energy meter can withstand is 1100 watts.

Secondly, consider how many electrical appliances can be plugged into one socket. If the sum of the maximum power of all electrical appliances does not exceed the power of the socket, there will generally be no problem. When using sockets with more than three pairs of jacks and using high-power appliances such as air conditioners, rice cookers, rice cookers, and electric water heaters at the same time, you should first calculate the total power of these appliances. If the limited power of the socket is exceeded, the socket will heat up and burn out due to excessive current. At this time, the number of electrical appliances used at the same time should be reduced to keep the total power within the allowable range of the socket.

In addition, the installed knife switch must use corresponding standard fuses (air switches are commonly used, and fuses have basically been eliminated). Do not use other metal wires instead, otherwise it may cause fire and damage the electrical appliance. If a fire is caused by a household appliance catching fire, the power must be cut off first before putting out the fire to avoid electric shock and injury.

Use a protector when voltage fluctuations are large. In daily life, instantaneous power outages or large fluctuations in power supply voltage often occur, which is a threat to refrigerators. If the power supply is restored within a short period of time (3 to 5 minutes) after a power outage, the starting current of the refrigerator compressor will be several times greater than the normal starting current, and the compressor may be burned.

Dear students, for a long time, the safety of electricity in student dormitories has been one of the important issues of great concern to the school. one. Especially in winter, illegal use of electricity in student dormitories increases.

Dear students, student dormitories are important places for everyone’s daily life and study. Strengthening safety awareness and creating a safe and good dormitory environment are of great significance to the safety and stability of the school.

Some time ago, our teachers confiscated some students’ mobile phones and chargers, as well as electrical appliances used illegally in the dormitory. Some students did not understand and thought the school’s regulations were unreasonable. Please think carefully about why? The purpose is not to protect the personal safety of students. Students, ignoring the safety of electricity will bring painful lessons:

1. On June 28, XX, at around 17:00, Zhang Ran, a junior student in the physics department of a university in Hebei Province, returned home after class. In the dormitory, privately connected wires were connected, and the strong current instantly knocked Zhang Ran to the bed. 120 emergency doctors rushed to the scene and performed rescue operations immediately. However, none of this could save the life of Zhang Ran, who was only 22 years old.

2. What happened in Shanghai: On November 14, XX, students in dormitory 602 of Shanghai Business School used the Heater the night before. After turning off the lights and the power outage at 22:30, they forgot to plug in the Heater. On the power socket and went to bed. The power was restored at 6:00 in the morning while they were still sleeping. The heat plugged into the power outlet quickly boiled away the remaining water, quickly causing overheating and eventually burning. The fire spread rapidly and caused excessive fireworks. Four girls jumped from the balcony of the dormitory on the 6th floor to escape before the firefighters arrived. Unfortunately, they all died.

From the above two tragic examples, we can see how dangerous it is to pull wires privately and use electrical appliances illegally. The school will place special emphasis on electrical safety in every year's freshman orientation education and regular safety education.

However, the reason why violations still occur is because some students have a sense of luck when it comes to using illegal electrical appliances and making random connections. They believe that charging mobile phones and using power strips will not cause any serious consequences, and their safety awareness is extremely weak.

Students "When you ignore safety, you are already standing next to danger." For your own sake, as well as for the parents and the school who are concerned about your healthy growth, we once again appeal to everyone that "safety use of electricity starts with me." Only teachers and students in the school will attach ideological importance to school safety education and respect human life. Only by doing so can we ensure that everyone can grow up safely and healthily in school.
