Dear, find <> for you

What are the causes of electrical accidents1The production management is chaotic, the power transmission authority of the enterprise is not centralized and uniformly managed, and the multi-headed leadership causes the factory to stop the power or power transmission by mistake, resulting in the shutdown of production and personnel. 2.

Electrical staff dereliction of duty, illegal operation, not according to the requirements of the work ticket to operate or do not count the start of the ticket for blind operation, resulting in power outages, electrical equipment short circuit collapse or personnel **. 3.The relay protection of the power supply system is not perfect, the fixed value is not matched or the fixed test is not strict, and the switch is misoperated or refused, resulting in power failure or expanding the scope of the accident.

The main reasons can be divided into the following aspects: 1. Human factors: including illegal operation, lack of professional skills, sloppy and irresponsible work, lack of safety protection, etc.

2. Equipment factors: the equipment is outdated, the insulation is aging, the capacity is insufficient and overloaded, and the equipment should not be repaired or replaced. 3. Management factors:

The rules and regulations are incomplete, the on-site management is chaotic, and the leaders are blind to the layman. In addition to this, there are weather factors such as lightning strikes, heavy rain, snow and ice, extreme heat, etc.

According to the basic elements that constitute an accident, electrical accidents can be divided into five categories: electric shock accidents, electrostatic accidents, lightning disasters, radio frequency hazards, and circuit failures.

1. Electric shock accidents are caused by the energy of electric current. Electric shock is the harm of electric current to the human body. The injury of electric current to the human body can be divided into electric shock and electric injury. The vast majority of sock burning** accidents involve electric shock.

2. Electrostatic accident refers to the relatively static positive and negative charges accumulated due to the relative movement, contact and separation of certain materials in the production process and the operation process of the staff. Electrostatic voltages can be as high as tens of thousands or even hundreds of thousands of volts, which can generate electrostatic sparks in the field. In fires and hazardous locations, electrostatic sparks are a very dangerous factor.

3. Lightning disasters are atmospheric electricity. Lightning discharge has the characteristics of high current and high voltage. The release of its energy can be extremely destructive. In addition to destroying facilities and equipment, lightning strikes may also directly injure people and animals, and may also cause disasters.

4. Radio frequency radiation hazard is electromagnetic field injury. The human body absorbs radiation energy under the action of high-frequency electromagnetic fields, so that the central nervous system, cardiovascular system and other parts of the human body will be damaged to varying degrees. RF radiation hazards also manifest themselves as induced discharges.

5. Circuit failure is caused by loss of control of power transfer, distribution and conversion. Circuit faults, such as disconnection, short circuit, grounding, leakage, misclosing, mis-dropping, damage to electrical equipment or electrical components, etc. Electrical wiring or electrical faults can affect personal safety.

Legal basis

Regulations on the Reporting, Investigation and Handling of Safety Accidents in Distress and False Property".

Article 3 According to the personnel or direct economic losses caused by production safety accidents, accidents are generally divided into the following levels:

1) Particularly filial piety major accidents refer to accidents that cause more than 30 deaths, or more than 100 serious injuries (including acute industrial poisoning, the same below), or direct economic losses of more than 100 million yuan;

2) "Major accidents" refers to accidents that cause the death of more than 10 people and less than 30 people, or the serious injury of more than 50 people and less than 100 people, or the direct economic loss of between 50 million and 100 million yuan;

3) "Relatively large accidents" refers to accidents that cause the death of 3 to 10 people, or the serious injury of 10 to 50 people, or the direct economic loss of between 10 million and 50 million yuan;

4) "General accidents" refer to accidents that cause the death of less than 3 people, or the serious injury of less than 10 people, or the direct economic loss of less than 10 million yuan.

The production safety supervision and management department may, in conjunction with the relevant departments, formulate supplementary provisions for the classification of accidents.

For the purposes of paragraph 1 of this Article, the term "above" includes this number, and the term "below" does not include this number.

Electrical accidents include personal accidents and equipment accidents. Both personal accidents and equipment accidents can lead to accidents, and both are likely to occur at the same time. An electrical accident is an accident associated with electrical energy.

Loss of control of electrical energy will cause an electrical accident. According to the form of electrical energy, electrical accidents are divided into electric shock accidents, electrical fire accidents, lightning accidents, electrostatic accidents, electromagnetic radiation accidents and circuit accidents.

1) Electric shock accidents.

An electric shock accident is an accident caused by the amount of electric current. Electric shock accidents are divided into electric shock and electric injury. An electric shock is an injury caused by an electric current being passed through the body.

Electrical injury is an injury caused by the conversion of electric current into heat, mechanical and other forms of energy on the human body. In 8.5 percent of these electric shocks**, electric shocks are the result of 8.5 percent of these fatalities, but about 7.0 percent of them contain an element of electrical injury.

2) Electrical fire accidents.

Electrical fire** accidents are caused by electrical sources (sparks and arcs; Electrical installation hazard).

3) Lightning accidents.

Lightning accidents are caused by nature's positive and negative charge-shaped energies, when electricity is intensely charged.

4) Electrostatic accidents.

Electrostatic accidents are accidents caused by relatively stationary positive and negative charge forms of electrical energy generated in the process or in people's activities.

5) Electromagnetic radiation accidents.

Electromagnetic radiation accidents are accidents caused by the amount of electromagnetic wave forms. Radiated electromagnetic waves Electromagnetic waves at a frequency of 100 k h z. In addition to electrical equipment, high-frequency metal heating equipment (such as high-frequency quenching equipment, high-frequency welding equipment), high-frequency medium heating equipment (such as high-frequency heat sealing machine, insulating material drying equipment) are also radiation risk equipment.

6) Circuit accidents.

Circuit accidents are accidents caused by the development of circuit faults such as power transfer distribution, loss of control, or damage to electrical components. Wire breakage, grounding, leakage, sudden power failure, mismatched power transmission, and damage to electrical equipment are all circuit faults. If the circuit fault is not controlled, it will develop into an accident.
