The basic management system of the power supply system is "three systems and two votes."
The "three systems" refers to: shift system, circuit inspection system, and regular equipment testing system. "Two votes" means: operation ticket and work ticket. "Three systems, two votes" is an important measure to guarantee the safe and stable operation of the transformer (or distribution) station.
Transfer system: Post employees must accurately and timely record the various situations that occur on duty. Carefully hand in hand (changing heads of duty and duty shifts alternately, attendants and watchers alternate) to maintain the continuity of production and ensure the normal operation of equipment. If the shifter does not arrive, the shifter shall immediately report to the relevant leader and shall not arbitrarily leave the production (work) position until he or she is transferred to another person or with the consent of the leader. The shift shift system is a strict and rigorous duty. An important system that guarantees continuous, safe operation must be implemented in a serious and serious manner. The shift staff should arrive at the class 30 minutes before the shift, and the shift should be recorded and signed by the shifter. When changing shifts, changers should do the following: a. Refer to the operation logs and various logbooks; b. Inventory safety tools, equipment and related spare parts materials, and submit relevant keys; c. Check equipment operation status, test each Kinds of signals, alarm devices, DC bus voltage insulation monitoring, etc.; d. Check the operation of substations and accidents; e. Check the operation tasks and maintenance work, including task tickets and work tickets to be executed. When switching operations are being performed, no shifts shall be made and shifts shall be made until the shifts are completed. f. Check the implementation status of various work tickets and on-site safety measures and the number and location of grounding
Wires. Persons who are sick, drunk or mentally unstable may not change classes. In this case, the shifter may refuse to attend the shift and report to the supervisor in time. In the event of an accident occurring during the alternation process, it shall be immediately suspended and alternated, and the shift shifter shall be responsible for handling. The shifter may assist in the handling and wait until the end of the accident treatment or come to an end. After obtaining the consent of the on-duty dispatcher, he shall perform alternate procedures.
Equipment periodical testing system: The equipment periodical testing system refers to the system that is specially formulated for the purpose of ensuring the regular maintenance and testing of the equipment, ensuring the reliable operation and backup of equipment, eliminating hidden dangers in time, and ensuring safe operation. Regular maintenance test items: a. Each shift shall be tested once for various signal devices, insulation monitoring and capacitive energy storage devices; b. The reclosing device shall be tested once a week and shall be selected when the weather is clear and windless; c. mid-monthly Clean the battery room once; d. Test the voltage, density, and liquid temperature of the marked battery once every day, and do it once every half month.
The correct operation of the switching operation is an extremely important task to ensure the safe operation of the substation. Substation operators must implement it carefully and be meticulous. The switching operation must be filled with operation tickets.
