What are the five preventions of malicious misoperation accidents?

1. Prevent the circuit breaker from being opened and closed by mistake:  The circuit breaker is an important device used to protect and control the circuit in the power system. The circuit breaker that is opened or closed by mistake will cause the protection of the power system to fail, which may cause serious consequences such as equipment damage and power outage.

2. Prevent the disconnector from being pulled and closed under load: The disconnector is used to isolate the circuit. Operating the disconnector under load may cause arcing, which may damage the equipment or cause a fire.

3. Prevent the earthing switch from being closed or the wire from being connected under power: The earthing switch is used for grounding protection. Operating the earthing switch under power may cause electric shock accidents and may also cause damage to the equipment.

4. Prevent the circuit breaker/disconnector from being closed with the earthing switch or the grounding wire connected under power: Operating the earthing switch or the grounding wire under power may cause the current circuit of the equipment to change, resulting in abnormal operation of the power equipment.

5. Prevent the accidental entry into the live interval: The live interval is the interval between the equipment in the power system. The accidental entry into the live interval may cause electric shock or other safety accidents.

Impact Analysis

1. Personnel safety: Five-prevention malicious misoperation directly affects the safety of operators, leading to serious consequences such as electric shock, burns and even death. The operating environment of the power industry is complex, and operators need to be vigilant at all times.

2. Equipment damage: Misoperation may cause equipment failure and damage, increasing the cost of equipment maintenance and replacement. After the equipment is damaged, repairing it will take a lot of time and human resources, affecting the normal operation of the power system.

3. Power supply interruption: Equipment failure caused by misoperation may cause large-scale power supply interruption, affecting the normal power consumption of residents and enterprises, and causing economic losses.

4. Legal liability: Misoperation in the power industry may lead to legal liability, and the relevant responsible persons may face penalties. At the same time, the company may also face compensation and reputation loss.

5. Operation efficiency: Frequent misoperation will reduce the operating efficiency of the power system and increase operating costs. The company's investment in safety management and operation training will also increase.

Preventive measures

    In order to effectively prevent five-prevention malicious misoperation accidents, power companies can take the following measures:

1. Strengthen training: Regularly conduct professional training for operators to improve their safety awareness and operation skills. Especially before new equipment is put into use, comprehensive training must be carried out.

2. Improve operating procedures: formulate detailed operating procedures and emergency plans to ensure that there is a basis for operation and reduce the possibility of misoperation.

3. Introduce technical means: use modern technical means, such as automation equipment, monitoring systems, etc., to reduce the frequency of manual operation and improve the safety of operation.

4. Regular inspection and maintenance: Regularly inspect and maintain power equipment, timely discover and eliminate hidden dangers, and ensure the normal operation of equipment.

5. Establish a responsibility system: clarify the responsibilities of personnel at all levels, form a good safety management culture, and improve the overall safety management level.
