Good Life, Healthy Home, Four Scenes, Home Electricity Safety
[PConline talk] From Faraday's invention of the first electric motor through electromagnetic induction, people's production and life can no longer be separated from the existence of electricity. The extensive use of electricity has opened up a new era of electrical appliances, which has greatly promoted the rapid advancement of social productivity and greatly facilitated people's lives. Some time ago there was an investigation: Let your mobile computer break the internet for a week. Can you do it? The author thinks that there are still many people who can do it, but what if you let your family lose power for a week? Probably everyone will hesitate. We haven't had electricity in our generation and we haven't had it. The role of electricity is so important and extensive, but how much do you know about the safety of electricity? Today Xiao Bian took everyone to seriously understand the safety issues that you should pay attention to under the four scenarios. Family circuit knowledge We all know that we have learned the physics of junior high school. The home circuit is generally composed of a household line, a power meter, an air switch, an insurance device, an electrical appliance, a socket, a wire, and a switch. The size of the household's household entrance line is designed in advance according to the size of the home area and the amount of electricity used. Under normal circumstances, the household electricity load is fully affordable. We do not need to understand the entire building process of the home circuit, but we need to know the concepts of several key circuit failures so that we can be prepared for disaster prevention, better prevent dangerous occurrences, and communicate well with maintenance personnel. Open circuit: The wire is disconnected, the contact is bad, or the appliance is burned out. Short circuit: The wire in your home or the insulation of the appliance is damaged due to aging. Overload: too many appliances used at the same time! Power overload! Leakage: Improper wiring or electrical failure, the fire line is exposed conductive! In the common faults of the home circuit, overload and leakage are easy to check, and short circuits and open circuits are more difficult to check. If any of the above occurs, if you cannot find out where the problem is, and you do not have full assurance, it is recommended that you directly pull down the insurance gate and call maintenance personnel. One thing that needs to be pointed out specifically: Do not use wire, copper wire or Aluminum Wire instead of a fuse! The use of fuses is strictly limited based on the total current of household electricity. The thicker the fuse, the higher the rated current and the fusing current. The fusing current is usually twice the rated current. The specification of the fuse should be equal to or slightly greater than the total current when all the electrical appliances in the circuit are working. Living room electricity: Choosing a good row, people walk The living room is the main activity place where people are concentrated, and it is also the place where the electrical appliances are relatively concentrated. The electrical appliances concentration means that the total power of the electrical appliances is large, so it is necessary to install a socket with a better quality and sockets. It is best to distribute the electrical appliances across different outlets. Once the load is too high, it may cause overload and short circuit. With regard to the selection of sockets and sockets, the author has some tips. Smart sockets and sockets are now very hot, but they are also inseparable from traditional circuit structures and copper materials. Whether it is smart or not, when it is selected, the first thing to watch is to protect the door. Use a screwdriver or a small key to smash one side of the two holes and a hole below the three holes. Use a little effort to gain access to the unilateral protection door. Equal to no. This socket is obviously not safe enough. The second thing to look for is copper material. If you see it is bright yellow through the jack, then give it up. Brass easily rusts, and its texture is soft, and its conductive properties deteriorate as time passes. If the color of copper is purple, it is better. Copper is tough and does not easily rust. It's not enough to look directly at it, but generally you must open it up. Many sockets are jacks. Copper is used here, and brass is used inside. It is also easy to rust. Even if you use copper, you have high points. Most brands of copper pieces are several pieces of splicing, with rivets interface, so that the interface will also generate heat, affecting the conductivity. Compared with the current technology, the current brand will use the entire piece of copper as the copper part inside, so that the conductive performance is greatly improved. Many small partners have no one to go out of power, use the power-off habit, and always think that the danger is far from being taken seriously. Most of the switches of the electrical appliance are designed on the secondary side of the transformer. Only the primary coil that is directly connected to the power supply is not disconnected from the switch. The electrical appliance is always in an energized and heat-generating state. Waste of electricity is not said. The electrical insulation layer of the primary coil may also be carbonized. Short circuits can easily cause fire. In addition, during the rainy season, thunder and lightning will destroy electric appliances through electric wires, and it is easier to “fire and burn†without power. Therefore, to remind everyone to develop the use of finished electrical appliances to disconnect the power, it is best to unplug the good habits of the plug, this is harmless. Electricity in the bedroom: use lighting with caution and sleep safely The bedroom is a resting place for sleep. It is usually a quiet place to decorate. At night, a lamp hangs on a lamp and looks very artistic. Maybe someone else will buy some different colorful lights to decorate their bedroom. The more beautiful things, the more potential risk factors are. The improper use of lighting can cause fire and threaten people's personal safety. The surface temperature of the lamp during use is very high, including the energy-saving lamp also emits a lot of heat, so no flammable items must be decorated around it. If you purchase floor lamps, bedside lamps, and other removable lighting at home, keep lighting and curtains and other fabric products away. Many people are accustomed to placing a row at the bedside for mobile phone charging, night light, etc., which is very convenient. Although it feels convenient to place rows and bars at the bedside, it is a hidden danger for home safety. Taking mobile phone charging as an example, charging is done at the bedside. Should the mobile phone explode, the first person will directly injure the person at the bedside, and the second will light the bedding product, causing a fire. The temperature in winter is very cold. The elderly and children may use electric blankets in bed. In fact, Xiao Bian does not recommend using it. If you must use it, remember that you must not use electric blankets on your bed. There are electric wires inside the electric blanket. The soft bed is too soft and it will fold and fold the electric blanket. This will easily break the electric heating wire and cause fire. A better suggestion is to warm up the empty bed in advance and remove the electric blanket before the person goes to bed. Kitchen electricity: Do not wet hands, pay attention to the electrical layout The kitchen is the place with the highest risk factor in home safety, where accidental injuries are most likely to occur, such as electric shocks, cuts, burns or burns. When cooking in the kitchen, you must pay special attention to the details in order to ensure that nothing is lost. Many small partners washed dishes before cooking, poured oil into the pan, and found that the cooker had not been plugged in. Under no hurry, they had just picked up the plugs after they had just dried their hands. This is particularly dangerous, Xiao Bian because it was so charged. In the wet hand condition, it is not only impossible to plug the plug, nor touch the power switch of various appliances. The socket wires in the kitchen must not be placed arbitrarily. A protective screw-type safety cover should be installed on the power switch to prevent splash leakage. Kitchen microwave ovens, refrigerators, and sterilizers should be kept away from induction cookers and gas to avoid short circuits. When dealing with built-in appliances, the edge should be reserved so that if the appliance fails, it can be easily removed. Some appliances have different requirements for voltage and current, but also need to be equipped with a ballast to reduce the voltage and limit the current. Finally, the kitchen must pay attention to moisture and ventilation. Bathroom electric power: Install electric water heater, make waterproof measures Electric appliances that must be indispensable in the bathroom are electric water heaters. According to appliance maintenance personnel, the main reason for accidents in electric water heaters is that there is no grounding wire or wrong grounding wire. It is best to find a professional when installing. Most of the houses are now connected to the ground, but some old floors are not. Some users simply connect the ground line to the water pipe. In fact, this is very dangerous. In a wet environment, if a short circuit or electric water heater leaks, it can easily cause an accident. A user who once reported that he felt numb during bathing may be connected to a water pipe in a residential building. The bathroom is relatively humid and the electric lamp exposed to the humid air is often exposed to water vapor. The metal inside is prone to rust, causing no damage to the lamp, and severe short circuit. Therefore, it is recommended that the switches and lights in the bathroom are best to be waterproof, and the waterproof switch and the interior of the lamp have a much higher security. In addition, do not place a washing machine in the bathroom. Long-term working in a humid environment, the edge of the washing machine will rust, and the washing machine in the work of leakage occurs. Therefore, in order to protect personal safety and maintain the washing machine, it is best not to place the washing machine in the bathroom. The full text concludes: Electricity can bring people light and provide energy to people, but it can also cause disasters for people, just like water can carry a boat and overturn it. Household electrical safety is related to people's lives and property safety. You may think that these problems mentioned in this article are often not paid attention to, that you are far away from danger, but you are afraid of ten thousand if you are afraid. Only pay attention to the process of using electricity. In every detail, the danger is naturally away from you.
