In daily life, electrical wiring aging, short circuit, fire accidents are very easy, and you must be familiar with these things about electrical safety.
First, the main reason for the electrical circuit
1.The two wires of the line short-circuit AC collide with each other and short-circuit, and the direct circuit does not pass through the equipment with the wire, because the loop current will increase instantaneously, and the larger current passes through the thin wire, and the temperature generated by the excessive heat generated by the large resistance is enough to burn off the surrounding flammables.
2.Poor contact can also cause excessive resistance to catch fire, which can occur when the heat burns the wire.
3.The line is overloaded, and once the current of the wire exceeds the current carrying capacity it bears, the more it exceeds, the greater the heat, which will also lead to the tragedy of the wire.
4.The problem of wire leakage and leakage must attract people's attention, due to the poor insulation of wire insulation and bracket materials, so that current is generated between wires, wires and earth, and leakage is also one of the main causes of fire.
Second, how to prevent electrical short circuit?
1.Choose qualified electrical products, unqualified electrical products may be cheap, but easy to cause short circuit, fire and electric shock hazards, so try to choose products with larger scale, better product quality and service quality.
2.Do not pull the wires privately, do not pull the wires privately for convenience, this may cause a short circuit and cause a fire.
3."Special plug special" uses several high-power electrical appliances in a socket, and the wires connected to the socket are often prone to accidents because the wire diameter is too small, such as burning out the wire or even causing fire, so it is necessary to achieve "special plug special".
4.Regular inspection of electrical appliances should be checked before use, maintained after use, and placed in moisture-proof, sunscreen, ventilated, away from flammable and explosive materials. If there is an electrical circuit, first cut off the power supply, and then use a fire extinguisher to extinguish the fire, not directly extinguished with electricity, in order to prevent electric shock or electrical appliances from hurting people.
5.When the power supply is cut off before leaving, when the electrical equipment is not used for a long time, the switch should be cut off or the bolt should be unplugged to ensure that the electricity is used in a standardized manner and the power is cut off when people leave.
