Recently, the cold air is constantly coming, and the pace of winter is getting closer and closer. Many children have been wrapped in down clothes and used air conditioning, warm baby and little sun. But while these heating devices warm us, they also bring the risk of electrical fire

There are a large number of potential electrical fire hazards, which have a certain concealment and incubation period. Once they occur, it is very easy to cause malignant fire. "Blue friend" reminds everyone to check the electrical circuit regularly and replace it in time if there is aging and damage; Check the electrical appliances used for a long time. If you find dirt, please clean it in time.

Electrical fire generally refers to the fire caused by the thermal energy (such as high temperature, arc and electric spark) released due to the failure of electrical lines, electrical equipment, appliances and supply and distribution equipment and the energy released without obstacles (such as the hot surface of electric heating appliances) to ignite the body or other combustibles under the combustion conditions, including the fire caused by lightning and static electricity. The main causes of household electrical fire are as follows: first, on the electrical circuit; Second, on electrical equipment and appliances.

Electrical fire characteristics

one

Seasonal

The main reasons are summer and winter. In summer, the average temperature is high and more electricity is used, which is easy to cause the temperature rise when using electrical equipment and damage the insulation of the equipment, resulting in fire. It is cold in winter, and improper use of heating appliances is easy to cause fire; In addition, the air humidity is low in winter, which is easy to generate electric charge. When dry things rub with the air, or fur rubs with skin, static electricity will be generated, resulting in frequent electrostatic fires.

two

With time (time period)

The main reason is that there is a large amount of domestic electricity at night, and some enterprises also produce at night. During the frequent operation and use of starting, running and closing electrical equipment and lighting lamps, there are dangerous factors caused by insulation damage, poor contact, overload operation, disorderly pulling lines and disorderly placing electric heating appliances, coupled with negligence, unnecessary patrol inspection is not carried out, Accordingly, it increases the possibility of electrical fire accidents.

03

Industrial

From the Department of electrical fire, the proportion of fire in industrial industry is high. The reason is that production and lighting consume a lot of electricity, with long power consumption time, long lines and many electrical equipment; Unreasonable installation, poor management and maintenance, violation of rules and regulations. The fire source of industrial electrical lines and equipment has large energy and is a strong fire source. Therefore, once there is a fire, the fire will spread quickly and cause great losses.

four

Artificial

The vast majority of electrical fires are caused by illegal operation or negligence. For example, the fire caused by non-standard welding operation in lamps and electrical appliances factory is the fire caused by illegal operation. Therefore, electrical fire is closely related to people's knowledge, technology, sense of responsibility and morality.

How to prevent electrical fire

1. Improve short-circuit protection and leakage protection, and install circuit breaker and leakage protector.

2. The line laying is standard, the connection is reliable, and the line diameter meets the use requirements.

3. The electrical equipment shall be intact, the equipment shall be reliably connected with the power supply, and the electrical equipment shall not be overloaded.

4. Install and use qualified electrical components and equipment.

5. Regularly check the insulation performance, electrical component function and equipment condition.

6. Do not pull or connect electrical lines without permission, and keep electrical equipment away from inflammables and combustibles.
