Damage to the socket can easily cause the power supply to fail during normal use, delaying work efficiency. It should be repaired in time. Poor wire contact, i.e. virtual connection, can easily cause fire or damage electrical appliances.
There are many reasons for poor socket contact. Ultimately, this is due to insufficient quality of the socket.
Generally, the copper parts of unqualified sockets are of poor quality, and the plug tends to loosen after being inserted, resulting in poor contact between the plug and the socket. Generally, the shell material of these sockets is insulated, and the flame retardant character is not very good. When the outlet is overloaded or short-circuited, the panel will melt due to heat and even cause a fire.
Thus, when purchasing prises, you should purchase qualified socket products which have been inspected by the national quality supervision department, otherwise it will pose a threat to the safety of family life.
Small household appliances such as hair dryers and electric kettles are available in almost every household. They are affordable and convenient to use, but we should not ignore the safe use of fire fighting equipment. Reminder: After use. electrical appliances or when going out for a long time, be sure to turn off the electrical switch and unplug the power plug to avoid accidents. Especially when using high-power electrical appliances such as hair dryers and induction cookers, do not place these items on them. chairs, sofas, mattresses and other combustible objects. Once the power is turned on, work in 8 seconds, it canignite surrounding objects and cause a fire. Here is a list of several dangerous electrical devices that are easily overlooked and should be alerted to by family and friends.
1. Hairdryer Someone already did such an experiment: the experimenter turned on a hairdryer without a heat shield, plugged it in, turned on the hot air and blocked the air outlet on the back< /p>
1. p>
After 8 seconds, the electric heating wire started to turn red. After a while, flames appeared at the air outlet. △De@ It’s shocking to see the firefighting in China. Attention. High temperature environment in summer
This cause of fire is more likely to be ignored. You should know these things about hair dryers
1 When buying a hair dryer, choose ordinary products. well-known chains and brands. A hair dryer with overheating protection function (it will stop atautomatically when the temperature reaches a high level).
2. When using the hair dryer, people cannot leave it, let alone place it on benches, sofas, mattresses and other combustible objects.
3. Do not use the hair dryer for too long to avoid the wire burning due to excessive temperature and causing a fire.
4. Try not to blow backwards. When the air inlet of the hair dryer blows on the ends of the hair, it can easily become tangled. Additionally, you need to keep a certain distance from your hair when blow-drying to avoid burns.
5. Do not use the hair dryer in the bathroom or in places with high humidity to avoid the risk of electric shock.
6. After using the hairdryer, remember to turn it on; Turn off the switch and unplug the power plug

7. Finally, don't forget toLeave the used hair dryer for a while and wait for the air outlet to cool down before storing it. You have to keep this in mind and leave nothing to chance. 2. A fire broke out near the Pingguoyuan community in Beijing. Thick black smoke billowed from a resident's home on the third floor and the entire house was on fire. After investigation, the cause of the fire was due to the aging of the electricity. short circuit strip.
The normal lifespan of a power strip is generally around three to five years, but it also depends on the quality and frequency of use. In case of aging such as damage, it should be replaced in time. . How to judge the aging of the power strip.
1. Judging from the appearance, frequent use or slipping can easily damage the hardware of the electrical outlet. In the event of a break, dust can enter the circuit and cause easycause a short circuit, leading to a fire.
2. Look at the power cord. The power cord is prone to "exposed copper" after using it for too long, which can easily cause a short circuit.
3. Look at the electrical outlet. There are two copper plates inside the electrical outlet. During frequent plugging and unplugging, the elasticity of the copper plates will weaken, which can easily cause virtual connection or poor contact. the socket strip, and also the cause This is what is often called
the “misconnected” phenomenon, which can easily cause arcing or sparking. In addition, if multiple high-power electrical appliances are used at home at the same time, they will be easily overloaded and cause safety hazards.
The circuit is easy to merge. Be careful when purchasing this type of power strip
1. Hole pluguniversal The universal hole socket is designed to be compatible with foreign two or three prong plugs (such as British standard, American standard, European standard plugs, etc.). There will be situations where the socket is too large, which can easily cause electric shock accidents, and the contact area between the socket blade and the electrical plug is too small, which which can easily cause the blade to overheat and cause a fire.
2. There is no safety door in the socket. If naughty children accidentally touch it with fingers or metal objects, it is very easy to cause electric shock. A qualified power strip looks like this
When purchasing, be sure to note that the product is marked with "3C certification". The socket has a copper foil to elastically block the safety door. Between each of the three sockets, and the wires are added.Grossly reduce wire heating and slow down power cord aging. Everyone should try to choose classic brand sockets to ensure safety.
3. Electrical appliances used beyond their lifespan. Electrical appliances are all electrical components that have a useful life. If used for a long time, they can easily cause phenomena such as insulation performance degradation and fire. Come see how long these appliances in your home have been in use.
01-Lifespan of the TV: approximately 8 years. In the hot summer, you should pay more attention to leaving a certain distance between the TV and the wall to dissipate heat. outside of the TV every six months to prevent component short circuits.
02-The lifespan of the water heater: approximately 8 years. A useExcessive operation of the water heater will affect the performance of the water heater and may also cause safety hazards. Try to separate dry and wet parts to avoid risk of electric shock and leakage.
03-The lifespan of the washing machine: approximately 8 years. Some old and vintage washing machines have aging circuits and corroded pipes, which are prone to water leaks and electricity leaks. Additionally, some bacteria can easily persist after prolonged use. The washing machine should be checked regularly for water and electricity leaks. It is best to install a splash guard or plastic baffle on the socket panel.
04-The lifespan of the refrigerator: about 10 years, and the maximum is not more than 12 years. If the refrigerator is leaking refrigerant, running too hard, vibrating, and consuming much more energy than itpreviously. This is “The characteristics of “excess”. In addition to not cooling the food and keeping it fresh, more importantly, it will consume more electricity and waste electricity bills.
05-Microwave oven life: 10 years when using a microwave oven to heat food, do not use metal utensils. Choose ceramic, glass and utensils. other heat resistant Do not heat eggs, liquids or food in sealed containers to avoid explosion: 5-8 years After prolonged use, the pressure resistance of the pot and related parts will be. significantly reduced. If it cannot withstand excessive pressure, it will cause explosion regularly and the rubber ring should be replaced every 2 years. If the accessories are damaged, please use original accessories. p>.
