The causes of electrical fires may be as follows

The causes of electrical fires are as follows:

Causes: aging lines, overload operation, poor quality, random connection, poor heat dissipation, heating of equipment joints and high temperature.

1, line aging, overload operation

With the arrival of hot weather, the number of electrical equipment such as air conditioners, refrigerators and electric fans has increased greatly, and the lines are aging and overloaded, which leads to short circuit and fire due to the damage of power insulation.

2. Poor quality

Improper installation or operation of electrical equipment and poor quality of installed electrical products are prone to power accidents!

3, private pull disorderly connect

Violation of safety regulations, unauthorized wiring, or ignorance of common sense of safe use of electricity are also important causes of electrical fires.

4. Poor heat dissipation

Poor heat dissipation of electrical appliances or motors, high temperature reduces insulation strength, leading to short circuit or motor burning. Entering summer is also a frequent period of car fires. Under high temperature conditions, a slight negligence in the production, transportation and storage of dangerous chemicals will lead to a fire.

5, equipment joint fever

Some electrical equipment, such as transformers, motors, capacitors, wires and connectors, will cause fires when their heating temperature rises during operation.

6. High temperature

High temperature weather is easy to form strong convective weather, which increases the speed of fire development and spread. It is hot in summer, with less precipitation and large evaporation, dry weather, low ignition point and easy to burn when exposed to open fire. Under the action of radiant heat, the fire will spread to adjacent buildings, forming a three-dimensional or large-scale fire.

Methods of preventing electrical fire

1. Improve short-circuit protection and overload protection, and install circuit breakers and leakage protectors.

2, line laying specifications, reliable connection, line diameter meets the use requirements.

3, electrical equipment in good condition, equipment and power supply connection is reliable, do not overload the use of electrical equipment.

4. Install and use qualified electrical components and equipment; .

5, regularly check the insulation performance, electrical components function and equipment condition, especially the reliability of short circuit protection and overload protection.
