Inferior switch sockets are like "time bombs", which endanger our personal and property safety at any time!
Cause analysis of fire accident;
1, the internal structure design of the switch socket is unreasonable.
In the switch, the state requires that the electrical gap be not less than 3 mm, and the inferior switch can't meet the requirements. The arc intensity generated by the switch at the moment of disconnection is very strong (arc refers to our common electric spark), which leads to the high temperature of 2000-4000 degrees on the contact surface, melting the metal on the contact surface, prolonging the circuit disconnection time, and there are potential safety hazards.
In the socket, the sleeve structure of inferior socket adopts rough riveting assembly structure, which increases the contact resistance, and the riveting position is prone to generate heat and high temperature, and the plastic material around the sleeve is easy to soften and deform, which leads to the displacement of the sleeve, and in serious cases, it forms a short circuit and causes a fire.
2. Choose inferior materials and cut corners.
The switch socket is made of inferior plastic material, which has low heat resistance, poor flame retardancy, impact resistance and aging resistance, which will lead to the decline of the comprehensive performance of the switch socket and cannot guarantee the normal use of the switch socket. In the long run, it will leave a fire hazard.
The electrifying ability of the metal parts of the switch socket is related to the material conductivity of the parts and the cross-sectional area of the current-carrying parts. Some switch sockets use cheap copper materials, which have poor conductivity. In addition, they cut corners, use very thin and narrow metal parts to reduce the cross-sectional area, and the metal parts generate too much heat, which is easy to cause safety accidents.
3. Low rated load and easy to overload.
The switch socket is marked with rated voltage and current. When the power of lamps and appliances connected in the circuit is too high (note: power = voltage ⅹ current), the current passing through the working circuit will increase with the increase of power (the voltage is relatively stable), resulting in the current passing through the switch socket exceeding the rated current. According to the thermal effect law of current, the greater the current in the circuit, the higher the temperature rise, and the high temperature for a long time may damage the switch socket, which may cause a fire in serious cases.
Cause analysis of electric shock in human body;
When the switch is turned on, a strong arc will be generated. People often turn on the switch with wet hands, which reduces the insulation resistance between the human body and the insulation part of the switch and causes insulation breakdown. Or there is too much water on the hand, and the structure of the inferior switch is loose, and the water flows into the contact switch, so that the switch directly forms a path current with the human body and flows to the earth to form a loop, causing an electric shock accident to the human body.
