Lightning protection safety phrases

1. Handwritten report on lightning protection safety knowledge

Lightning should be a natural phenomenon, but if it is not controlled and prevented, it can also be regarded as a natural disaster. Accidents that can cause casualties and property damage. Although it is an irresistible natural factor and the harm and consequences it causes are very serious, it can be avoided by strengthening prevention and control. Therefore, it is very important and necessary to strengthen the study of lightning-related safety knowledge before the summer thunderstorm season in order to take corresponding safety precautions.

1. The generation of thunder and lightning

When dust, ice crystals and other substances in the air roll and move in the clouds, they go through some complex processes, causing these substances to be charged with positive and negative charges respectively. charge. Protruding objects and metals on the ground will induce positive charges. As the electric field gradually increases, thunderclouds will form a downward leader, and objects on the ground will form an upward reflow. When the two meet, they will form a discharge to the ground. This can easily cause lightning disasters.

2. The main characteristics of lightning

The impact current is large, the time is short, the lightning current change gradient is large, and the impact voltage is high: the alternating magnetic field generated by the powerful current can induce a voltage of Up to hundreds of millions of volts.

3. Damage caused by lightning

When lightning strikes a building directly, the strong lightning current causes the water in the building (structure) to heat, vaporize and expand, resulting in a large amount of damage. Mechanical forces that cause buildings to burn or explode. In addition, when lightning strikes the air-termination device and the current flows to the earth along the down conductor, the potential to the ground increases and may jump to nearby objects, which is called lightning "counterattack", resulting in fire or personal injury. casualties. Sensing the connected wires will cause strong damage to the equipment. When lightning approaches overhead pipelines, high-voltage shock waves will invade the room along the overhead pipelines, causing high current to be introduced, which may cause equipment damage or personal injury or death. If there are combustible materials nearby, it can easily cause a fire.

1. Unswervingly adhere to the policy of “safety first, prevention first”

"Safety first, prevention first" is the basic policy for the production and construction of electric power industry enterprises, and is the basis and guarantee for the electric power industry to achieve sustained, rapid and healthy development. During the period of establishing and developing the socialist market economy, we must continue to adhere to this policy. Electric power enterprises must properly handle the relationship between safety and efficiency, safety, quality and speed, and safety and diversified operations in all tasks. When conflicts arise, they must first submit to safety. It is necessary to correctly handle the relationship between security and reform, security and development, so that reform promotes security, development must be safe, and security ensures the smooth progress of reform and development.

Electric power enterprises and institutions must prevent personal deaths and malignant accidents that have a major impact on society, eliminate major equipment damage accidents, and significantly reduce general accidents.

2. Comprehensively implement the safety production responsibility system at all levels with the administrative official as the first person responsible for safety.

The administrative officials at all levels of electric power enterprises and institutions, that is, the legal representatives, are the first persons responsible for the safety of their units and departments. They are fully responsible for safety work, coordinate and personally intervene in major issues in safety production . Administrative deputies at all levels must do a good job in safety work within their respective areas of responsibility and assume corresponding safety responsibilities. It is necessary to establish a safety responsibility system for all types of personnel at all levels, so that every leader, every functional department, and every professional position has clear safety responsibilities, and everyone is responsible for their own responsibilities. It is necessary to improve the safety production guarantee system, and all departments should cooperate closely to complete safety work together.

3. Improve and improve the safety supervision system

Electric power enterprises and public institutions must improve and improve safety supervision institutions, enrich safety supervision personnel, and form a complete top-down system within the enterprise. safety monitoring network. Safety supervision work can only be strengthened but not weakened. The Ministry of Electric Power Industry implements safety supervision over the electric power industry; each network and provincial bureau (company) exercises safety supervision functions over its affiliated enterprises. The safety supervisors of enterprises are production personnel and are responsible for safety supervision. They implement safety supervision of the entire process of power production and construction. Administrative leaders at all levels must actively support and not interfere arbitrarily so that safety supervisors truly have their duties and powers. 7. Safety publicity on lightning protection
