Working on electrical equipment, to ensure the safety of the organizational measures are the work ticket system, work permit system, work monitoring system, end system.
Electrical Equipment (Electrical Equipment) is a collective term for generators, transformers, power lines, circuit breakers, and other equipment in the power system.
Electrical equipment consists of two parts: power supply and power equipment. Power supply includes batteries, generators and their regulators. Electrical equipment including engine starting system and automotive lighting, signaling, instrumentation, etc., in the forced ignition engine also includes the engine ignition system.
Contents of electrical safety work:
(1) Research and take all kinds of effective safety technology measures.
(2) Research and promote advanced electrical safety technology to improve the level of electrical safety.
(3) To formulate and implement safety technology standards and safety technology regulations.
(4) Establish and implement various safety management systems.
(5) Carry out education on electrical safety ideas and electrical safety knowledge.
(6) To analyze accident examples and find out the causes and patterns of accidents from them.
If the basic cause of the accident, electrical accidents can be divided into the following categories:
(1) electric shock accident. The person touches the electrified body (or too close to the high voltage electrified body), due to the current flowing through the human body and the personal injury caused by the accident. Electrocution accident is caused by the current energy applied to the human body. Electrocution can be divided into single-phase electrocution, two-phase electrocution and step voltage electrocution.
(2) lightning and electrostatic accidents. Local range of temporary loss of balance of positive and negative charges, under certain conditions will be the charge of energy released, the human body caused by the injury or other accidents caused.
Lightning strikes can often destroy buildings, injuring people and animals, and may also cause fires; the greatest threat of electrostatic discharge is to cause fires or explosions, which may also cause injury to the human body.
(3) radio frequency injury. Electromagnetic field energy on the human body caused by the injury, also known as electromagnetic field injury. In the role of high-frequency electromagnetic fields, the human body due to the absorption of radiation energy, the organs will be subject to varying degrees of injury, thus causing a variety of diseases. In addition to high-frequency electromagnetic fields, ultra-high voltage high-intensity industrial electromagnetic fields will also cause some damage to the human body.
(4) circuit failure. Electrical energy in the transmission, distribution, conversion process, due to the loss of control and cause accidents. Circuit and equipment failures not only threaten personal safety, but also seriously damage electrical equipment.
