1, organizational measures:
(1) Strengthen the education of safety thoughts and improve the safety responsibility of employees.
"Electric Safety Work Regulations" is a life-saving regulation for electric workers, and "two votes" is the life ticket for electric workers. Failure to strictly implement the "safety regulations" and "two votes" is tantamount to joking with your own life. The electrical operator is the owner of the equipment and the direct executor of the electrical switching operation. Improving their safety responsibility and giving full play to their subjective initiative are the basis to prevent electrical misoperation accidents. Department leaders should also go deep into the on-site team, guide employees to formulate improvement measures according to the actual situation and existing problems of the team, so as to persevere, sound the alarm, be prepared for danger in times of peace, and further improve employees' awareness of safety responsibility and self-safety protection ability.
(2) Strengthen technical training and improve the quality of personnel.
With the continuous popularization and use of new equipment and technology in power system, operators should not only be trained in the theoretical knowledge of new equipment and technology, but also be trained in the operation coordination of primary and secondary equipment in switching operation, so as to avoid misoperation accidents caused by unfamiliar business of operators.
(3) Implement monitoring in place and strictly control the site quality.
The more important operation must be checked by professionals on site, that is, the general operation should be monitored in place, carefully operated and thought for 3 seconds. Practice has proved that putting operation monitoring in place, strictly controlling site quality and correcting habitual violations in time can not only effectively prevent the occurrence of electrical misoperation accidents, but also have great significance for improving the operation level of operators, shortening operation time and improving equipment utilization.
(4) Do a good job in political and ideological work to relieve employees' worries.
In safety production, we should do a good job in the political and ideological work of employees in a timely and effective manner, care about their sufferings, help them relieve their worries in time and become intimate people of employees. Strengthen employees' psychological training, enhance their self-adjustment ability, eliminate unnecessary psychological pressure, establish a stable and optimistic work attitude, and always put themselves into their work with the best mental state.
2. Technical measures: The implementation of the standardization, standardization and proceduralization of switching operation is often caused by the negligence of the operator and the omission of a certain link in the operation process. As long as the operators can strictly abide by the operating rules, misoperation accidents can be avoided. The electrical operation post is introduced into the switching operation with process management and whole process management as the main content mode, and the standardized, standardized and programmed switching operation is implemented.
Extended data:
Device for preventing electrical misoperation:
1. Mechanical interlock: mechanical parts (connecting rod, crank arm, shaft, pin, baffle, etc.). ) It is used to connect the operating mechanisms of circuit breakers, disconnectors and grounding switches with the cabinet door according to the design requirements of misoperation prevention procedures, so that the high-voltage switchgear can only operate correctly according to the specified procedures, and misoperation can be prevented through mechanical components (or combinations). The mechanical interlocking device is integrated with the high-voltage switchgear, which is an ideal interlocking device without additional operation. Mechanical interlocking should be preferred for interlocking of short-distance components (such as metal enclosed switchgear). Its disadvantage is that it is not easy to realize long-distance and lateral interlocking of equipment.
2. Program lock: It is a mechanical lock manufactured according to the design requirements of error-proof program and installed on the interlocking link of high-voltage switchgear. Program locks are generally divided into three parts: lock body, lock tongue and key. Only when the operator correctly operates the high-voltage switchgear according to the specified procedures can he get the key of the next operation from the program lock after completing the previous operation until all the operations are completed. The lock bolt prevents misoperation because the key can't open the lock. The program lock can meet the different operation requirements of the equipment such as vertical, horizontal and long distance, but besides the normal operation of the equipment, it is necessary to increase the opening and closing operation.
