Electrical accidents including personal accident and equipment accidents. Personal accident and equipment accidents may lead to secondary accidents, and both may occur simultaneously. Electrical accidents are associated with electrical accidents. From the energy point of view, the electrical power will cause loss of control accidents. According to the form of electrical energy, electrical accidents can be divided into electric shock, lightning accidents, static electricity accident, incident electromagnetic radiation and electrical equipment accidents.
1, electric shock,
Electric shock from the current and its conversion into other forms of energy caused by the accident. Into shock and electric shock accident injuries. Shock is the current directly on the body caused by injury. Electric current injury is converted into heat energy, mechanical energy and other forms of energy in the human body caused by injury. Electric shock accidents often happen suddenly, in a very short period of time causing serious consequences.
Commonly referred to as electric shock refers to the shock. Shock into direct contact and indirect contact electric shock electric shock. The former is the normal state of touching live electrical shock occurs when the charged body, also known as the normal state of shock; reach the normal state which is not charged, but an accident during a fault condition occurs when the body charged live electrical attack, also known as electric shock under fault conditions.
Electric shock into the arc burns, the current burns, skin metal, electric branding, mechanical injury, lightning eye and other injuries. Arc burns are burns caused by the arc discharge, is the most dangerous electric shock. Arc temperature up to 8000 ℃. Can cause a large area, deep burns, and even charred, burned limbs and other parts.
2, lightning accident
Lightning accidents are caused by nature, Chiang Kai-shek, the negatively charged form of energy caused by the accident.
3, electrostatic accident
Accidents are caused by static electricity or process arising from human activities, relatively static positive charge and negative charge in the form of energy caused by the accident.
4, electromagnetic radiation hazards
Electromagnetic radiation is incident radiation energy in the form of electromagnetic waves caused by the accident. Electromagnetic radiation refers to electromagnetic frequencies above 100 kHz transition. In a certain intensity of high frequency electromagnetic radiation under crossing, the damage suffered by the human body mainly as dizziness, memory loss, poor sleep and other symptoms of neurasthenia. In severe cases, in addition to increased symptoms of neurasthenia, but also associated with cardiovascular symptoms. Electromagnetic waves damage the human body there is a lag, and may affect offspring by genetic factors. In addition to harm the human body, the high-frequency electromagnetic transition can cause high-frequency induction discharge and high-frequency interference.
In addition to radio equipment, high-frequency metal heating equipment (such as high-frequency quenching equipment, high-frequency welding equipment), high-frequency dielectric heating equipment (such as high-frequency heat sealing machine, drying equipment, insulation materials), is electromagnetic radiation dangerous equipment.
In order to prevent electromagnetic radiation hazards, should be taken to shield, absorb other special precautions. For high-frequency shielding and protection of the plate with a mesh screen can be copper, aluminum or steel. Necessary, consider double-shielded. If the shield plate coated with tiny particles material, can reduce the reflection of electromagnetic transition. More effectively absorb the energy of electromagnetic waves, constitute the so-called absorption shield.
5, electrical equipment failures and accidents.
Gas system failure caused the accident, including: abnormal power failure, abnormal electric, electrical equipment damage, electrical wire damage and short circuit, disconnection, grounding, electrical fires.
Abnormal power failure in the normal production process, a sudden power interruption. This makes the production process into chaos, resulting in economic losses; in some cases, will result in accidents and casualties.
Abnormal live in normal circumstances should not be charged or which part of the production facilities unexpected live. Easily lead to abnormal persons Battery for CANON BP-808 charged hurt.
