Electrical equipment has many different operating states. To change electrical equipment from one operating state to another, a series of switching operations are required. The correct operation of the switching operation is related to the safety of people and equipment. . "Safety first, prevention-oriented" is a long-term guideline for electric power production. Continuous safety education and training on operational skills are one of the important measures to prevent electrical accidents. In the past few years, we have combined with the actual situation of substations, and summarized some specific practices to ensure the correct rate of switching operations.
First, strengthen the theoretical study of switching operations.
Our Liuyu area is responsible for the important load of the natural gas production and sales plant, the refining and chemical plant and other units, and the external environment is harsh. There are more than 20,000 switching operations per year. The operation is the focus of work and good The difficulty of safe work. In practice, we learned that because employees do not follow the switching procedures, the operation time is prolonged, the quality of operation is affected, and more serious personal and equipment accidents can occur, causing damage to state property and affecting the safety of Zhongyuan Oilfield Power Grid. run. We noticed that the operation in the year was concentrated in the preventive test and the spring maintenance. In combination with the actual work, we emphasized the ten steps of the operation of the switch in the safety study organized at the beginning of the year: 1 issuing the command and accepting the task 2 fill in the operation ticket; 3 review the operation ticket; 4 issue the operation command; 5 simulate the operation; 6 check the equipment; 7 record the ticket, reclaim and carry out the operation; 8 the operation quality check; 9 the operation report fills in the record; At the same time, explain the requirements and precautions of each step, for example: 1 For some attendants to have mutual trust and dependence when reviewing the operation ticket, we require the duty officer and the squad leader of the substation to separately sign and improve the signature. The correct rate of operation ticket filling. 2 For the operation of the reclamation operation, the operator should not rely solely on the monitoring, but should be aware of the contents of the operation. During the operation, the conversation and work unrelated to the operation cannot be performed. Through repeated learning, each employee can skillfully draw a program diagram of the top ten steps of the switching operation, and can clearly define the actual meaning and requirements of each step.
Second, strengthen the actual operation drill.
We have noticed that it is not enough to memorize the operation of the switch. The key is to practice more, strictly follow the procedure drills, and make the normative operation become a habitual behavior through repeated practice. We first look for two relatively skilled workers, one operation, one guardian, and follow the ten steps on the spare equipment. After the operation, each employee must evaluate. Then each shift will be drilled, and repeated and repeated, and constantly improved. There is always a gap between saying and doing. At the beginning, everyone was not used to it. However, after more than one month of training before each spring inspection, everyone’s operation level has improved significantly.
Third, strictly implement the supervision and inspection system.
Violation of the rules as an accident to arrest, the elimination of accidents is the purpose of our inspection. We require that the normal operation process must be carried out according to the operating procedures, even for a single operation. However, there are always individual employees who are lucky enough to work. I always feel that I have not had problems for a few years. The accident is far away from myself. We tell the staff that there are no accidents in violation of the regulations, but all accidents must be caused by violations. In the normal work of the education staff, the rules and regulations are strictly enforced. At the same time, we have increased the inspection and handling of non-procedural operations. , inspection, standardize the operation of employees, ensure the correct operation of the switch, and ensure the safety of people and equipment.
Fourth, constantly sum up experience. When standardizing the switching operation, it is necessary to continuously sum up the experience and find out the problems that are easily overlooked in the operation process and analyze them carefully. For example, after pulling the knife gate, check the operation quality. Usually, we only pay attention to whether the knife gate is opened or not, and it is easy to neglect to check whether the knife gate has defects. We have made important requirements for this, so that the operation quality can be guaranteed. Found a device defect. For example, in the operation of the three gas change inspection in April of 1999, when the 302 South Mother Knife Gate and the 301 North Mother Knife Gate were opened, the inspection found that there were burn marks on the 302 South A and C phases that were not found in the usual inspection. . The 6KV line of Liuyu Substation has serious electricity theft. When the equipment is repaired and grounded, there is a return power in a short time. Even if the ground wire is installed immediately after the electricity inspection according to the regulations, there is a live ground wire. Dangerous, we require the guardian to operate the ground wire while the phase-by-phase inspection is performed. By summarizing and improving the operation level of each employee, accidents are prevented.
Through the implementation of standardized switching operations, the purpose of summing up experience, improving technology, preventing accidents, and ensuring safety has been achieved. In the past five years, the Liuyu area has operated more than 90,000 times, and the correct rate of switching operations is 100%.
