3. I want to safety tips
I. Overview of electricity In the case of taking the necessary safety measures to use and maintain electrical equipment.
Electricity is a convenient source of energy, and its widespread use has formed the second technological revolution in modern human history. Powerful to promote the development of human society, to create a huge wealth of human beings and improve human life.
Second, the hazards of electricity If you do not pay attention to the safe use of electricity in production and life, can also bring disaster. For example, electric shock can cause personal injury or death, equipment leakage of electric sparks may cause fires, explosions, high-frequency power equipment can produce electromagnetic pollution.
Third, electricity safety 1. How to use electricity safely The summer heat is unbearable, air conditioning, electric fans have turned up. Because of the use of these electrical appliances caused by fire, electrocution accidents occur every year, how to use electricity safely and scientifically, is a major event that every family must pay attention to.
First of all, to consider the energy meter and low voltage line capacity. The power meter can withstand the electric power is approximated by the voltage multiplied by the value of the current, the civilian electricity voltage is 220 volts, such as the installation of 2.5 amperes at home, the power to withstand is 550 watts, such as 600 watts of rice cooker can not be used.
So the projection, 5A meter can withstand the power is 1100 watts. Next, consider how many appliances can be plugged into a single outlet.
If the sum of the maximum power of all the appliances does not exceed the power of the socket, there is generally no problem. With more than three pairs of sockets, and the purpose of the simultaneous use of air conditioning, rice cookers, rice cookers, electric water heaters and other high-power appliances, you should first calculate the sum of the power of these appliances.
If more than the limited power of the socket, the socket will be too large due to the current and heat burned, which should reduce the number of appliances used at the same time, so that the total power to stay within the permissible range of the socket. In addition, the installation of the knife gate must use the appropriate standard fuse.
Not to be replaced by other metal wire, otherwise it is easy to cause fire and destroy electrical appliances. If a fire is caused by a household appliance catching fire, the power supply must be cut off before putting out the fire to avoid electrocution and injury.
2. Safe use of electricity refrigerators, televisions, washing machines, air conditioners and other household appliances, the popularity of people's lives has brought a lot of convenience. However, it is important to pay attention to the safe use of power to avoid unnecessary injuries.
Appliances with metal casings should use a three-pronged power plug. Some appliances malfunction or moisture when the shell may leak.
Once the shell is charged, with a two-pronged power socket, the human body in contact with the possibility of electric shock. Power-consuming household appliances to use a separate power outlet.
Because cords and sockets have a specified current-carrying capacity, if a variety of appliances share a power outlet, when the current exceeds its rated flow, the wire will heat up, and the plastic insulating sleeve may melt and burn. When the voltage fluctuates, use a protector.
In daily life, instantaneous power outages or large fluctuations in supply voltage occur from time to time, which is a threat to the refrigerator. If the power supply is restored after a power failure in a short period of time (3-5 minutes), the compressor of the refrigerator is subjected to a start-up current several times greater than the normal start-up current, which may burn the compressor.
Fourth, how to use electricity safely 1, why the lighting switch must be connected to the firewire? If the lighting switch is installed on the zero line, although the lights do not light when disconnected, but the phase line of the lamp is still connected, and people think that the lights do not light, it will be incorrectly assumed to be in a power failure. In fact, the voltage to ground at each point on the lamp is still 220 volts of dangerous voltage.
If the lights go out when people touch these actually electrified parts, it will cause electrocution. Therefore, all kinds of lighting switch or single-phase small-capacity power equipment switch, only in series on the firewire to ensure safety.
2, single-phase three-hole socket how to install the correct? Why? Usually, single-phase electrical equipment, especially mobile electrical equipment, should use three-core plugs and matching three-hole socket. Three-hole socket has a special protection zero (ground) jack, in the use of zero protection, some people often only in the bottom of the socket will be the hole wiring stakes and the introduction of the socket that the zero line is directly connected to the socket, which is extremely dangerous.
Because in case the zero line of the power supply is disconnected, or the power supply of the fire (phase) line, the zero line is reversed, the shell and other metal parts will be brought to the same voltage with the power supply, which will lead to electric shock. Therefore, when wiring the special grounding jack should be connected to the special protective grounding wire.
The use of zero protection, the zero line should be from the power supply end of the special lead, and should not be used in the vicinity of the zero line introduced into the socket. 3, plastic insulated wires why it is strictly prohibited directly buried in the wall? (1) plastic insulated wire after a long time of use, the plastic will be aging cracked, insulation level is greatly reduced, when the line short-term overload or short-circuit, it is easier to accelerate the damage to the insulation.
(2) Once the wall is damp, it will cause a large leakage, endangering personal safety. (3) Plastic insulated wires directly buried, not conducive to line maintenance and repair.
4, why use the leakage protector? Leakage protector, also known as leakage protection switch, is a new type of electrical safety devices, its main purpose is: (1) to prevent electrical equipment and electrical wiring leakage caused by electric shock. (2) Prevent single-phase electrocution in the process of using electricity.
(3) cut off the single-phase ground fault in the operation of electrical equipment in a timely manner to prevent electrical fires caused by leakage. (4) With the improvement of people's living standards, the increasing number of household appliances, in the process of electricity, due to the defects of the electrical equipment itself, improper use and safety and technical measures are not favorable and caused by personal electrocution and fire accidents, to the people's lives and property brought about by the undeserved losses, and the emergence of leakage protector, to prevent all kinds of accidents, cut off the power supply in a timely manner to protect the equipment and personal safety, to provide a reliable and effective technical means. A reliable and effective technical means.
5, what is the main cause of electrocution? Statistics show that the main causes of electrocution accidents are the following: (1) lack of knowledge of electrical safety, flying kites near high-voltage lines, climbing high-voltage poles to pull out the bird's nest; low-voltage overhead line breaks without stopping the power to pick up the fire line with the hand; the blackout of electrified wiring hand touching the electrified body; touching the broken rubber cover the knife gate. (2) violation of operating procedures, electric connection lines or electrical equipment without taking the necessary safety measures; touching the damage to the equipment or wire; mistakenly boarding the charged equipment; electric connection lighting; electric repair power tools; electric mobile electrical equipment; with wet hands to screw the bulb and so on.
(3) Unqualified equipment, insufficient safety distance; two lines and one ground.
4. What does Knowledge of Electric Safety mean
Knowledge of Electric Safety provides a comprehensive introduction to safety education, general knowledge of safe use of electricity, knowledge of on-site emergency care, safety appliances, and knowledge of fire prevention and extinguishing, as well as related exercises.

5. Summarize the knowledge of safety with electricity common sense, summarize the precautions of safety with electricity, 100,000 fire. The best
1. each household meter must be equipped with a total insurance, meter should be equipped with a total knife gate and leakage protection switch. 2. electric lines and electrical equipment insulation must be good, lamps, sockets, switches and other electrically charged parts can not be exposed to prevent electrocution. 3. electrically connected to the operation of the notes: the operator must be wearing electrician's insulating shoes and look for a dry wood Ban pad to strengthen the insulating effect, wiring first to connect the low voltage, and the first to connect to the low voltage. When wiring, first connect the low-potential (zero) line, and then when connecting the phase line, the phase line and to be wired to contact before operation (in order to prevent the load mistakenly open the human body circuit caused by electrocution), at the same time, there should be a person to supervise the 4. Why must the lighting switch be connected to the firewire? If the lighting switch is installed in the zero line, although the lights do not light up when disconnected, but the phase wire of the lamp is still connected, and people think that the lights do not light up, it will be incorrectly assumed that it is in a state of power failure. In fact, the lamp on the points of the ground voltage is still 220 volts of dangerous voltage. If the lights go out when people touch these actually charged parts, will cause electric shock accident. So a variety of lighting switches or single-phase small-capacity power equipment switch, only in series on the firewire to ensure safety .

9. Electricity safety knowledge are included what
First, learn to see the safety of electricity signs
A clear and unified sign is to ensure that the safety of electricity is an important measure. Statistics show that many electrical accidents are caused entirely by the sign is not uniform. For example, due to the color of the wire is not uniform, mistakenly connect the phase line to the chassis of the equipment, resulting in the chassis charged, resulting in contact casualties.
Signs are divided into color signs and graphic signs. Color signs are often used to distinguish between a variety of different properties, different uses of the wire, or used to indicate a degree of security. Graphic signs are generally used to warn people not to go close to a dangerous place. In order to ensure the safety of electricity, must be strictly in accordance with the relevant standards for the use of color signs and graphic symbols. China's safety color marking using standards, basically the same as the draft international standard (ISD). Generally used safety colors are as follows:
1, red: used to mark the ban, stop and fire, such as signal lights, signal flags, emergency stop button on the machine are red to indicate that the "ban" information.
2, yellow: used to mark the attention of the danger. Such as "beware of contacts", "pay attention to safety" and so on.
3, green: used to mark safe and sound. Such as "work here", "grounded" and so on.
4, blue: used to mark the mandatory, such as "must wear a helmet" and so on.
5. Black: used to mark images, text symbols and warning signs of geometric shapes.
In accordance with the provisions of the regulations, in order to facilitate identification, prevent misuse, and ensure the safety of operation and maintenance personnel, the use of different colors to distinguish the characteristics of the equipment. For example, the electrical bus, phase A is yellow, phase B is green 7a64e4b893e5b19e31333365656566 color, phase C is red, open grounding line painted black. In the secondary system, AC voltage circuits are colored yellow, AC current circuits are colored green, and signal and warning circuits are colored white.
Second, the precautions for safe use of electricity:
With the continuous improvement of the standard of living, the life of electricity in more and more places. Therefore, it is necessary for us to master the following basic general knowledge of safe use of electricity:
l. Recognize and understand the main switch of the power supply, and learn to turn off the main power supply in case of emergency.
2, without hands or conductive objects (such as wire, nails, pins and other metal products) to touch, test the interior of the power socket.
3, without wet hands touching the appliance, without a wet cloth to wipe the appliance.
4, electrical appliances should be unplugged after use; plugging and unplugging the power plug do not pull the cord to prevent damage to the insulation layer of the wire caused by electric shock; the insulation of the wire peeled off, to be replaced in time with a new line or wrapped in insulating tape.
5, found someone electrocuted to try to turn off the power in a timely manner; or with a dry stick and other things will be electrocuted and electrified electrical appliances separate, do not use their hands to save people directly; the age of the students encountered this situation, should call out to adults to help, do not deal with their own in order to prevent electrocution.
6, do not arbitrarily dismantle, install power lines, sockets, plugs and so on. Even if you install a light bulb and other simple things, you have to turn off the power first, and under the guidance of parents.
