With the improvement of the living standards of residents
People's daily electricity consumption continues to increase
Many small hidden dangers are often overlooked for a long time
Eventually become a "hidden killer"
Generally, it refers to electrical wiring, electrical equipment, and appliances
and the failure of power supply and distribution equipment to release heat energy
Such as high temperatures, arcing, electric sparks, and non-faulty energy releases
The body is ignited under combustion conditions
or other combustible fires
There are several common causes
∨
01
Short circuit fault
Electrical equipment in the home will cause short circuits due to insulation damage, circuit disrepair, operation errors, etc. The heat generated by a short circuit causes combustion, which can lead to a fire.
02
Line overload
The selection of lines or equipment is unreasonable, the load current of the line exceeds the standard, and the long-term overload operation of the electrical equipment will cause the line or equipment to overheat and cause fire.
03
Poor contact
If the joint connection is not firm or tight, the pressure of the moving contact is too small, etc., the contact resistance is too large, and overheating occurs in the contact part and causes fire.
04
Poor heat dissipation
High-power electrical equipment, if there is a lack of ventilation and heat dissipation facilities or damage to ventilation and heat dissipation facilities, will cause heat accumulation, thereby causing fire.
05
Improper use
If electrical appliances such as irons and hair dryers are not used as required, flammable and explosive materials are stacked nearby, and forget to disconnect the power supply after use, it may also cause fire.
