There are masters who know the basic principles and concepts of substation equipment management and

Daily operation and maintenance.

1) Establish a strict operation management system, take responsibility for the person, and equip full-time technicians to conduct regular inspections of the equipment, which are as follows:

Check the spacer layer: check the normal operation display, clock; Check the zero drift, check the scale and measurement error of each voltage and current channel; Check the value area, and whether the fixed value is consistent with the fixed value notice; Check the remote signaling operation, and check the amount of data and status with the scheduling; Whether the plug-in is hot or loose.

Check the monitoring machine and the five-proof machine: whether the mouse and keyboard are flexible, and whether the connecting wires are loose; Whether the amount of data and the amount of state are consistent with the actual operation; Remote control ** condition; Check whether the protection information is consistent with the duty record at that time, and whether the action is correct; Check whether the computer has virus intrusion and whether the system is running well; Check whether the five-proof machine can enter the system correctly and perform the operation task correctly; Five-proof key charging, whether the function is normal; Check the automatic switching of the UPS power supply, and test the discharge time of the UPS power supply to see if it is qualified.

2) Defect management: Establish a defect management system and defect handling records, and the personnel on duty will find problems in time through daily inspection equipment and notify the relevant personnel to deal with them in a timely manner. Operational analysis, accident prediction, and anti-accident drills are conducted to ensure accurate and rapid handling of accidents and defects.

3) Dustproof: The adjacent road of the institute has a large amount of dust, and the equipment is cleaned regularly and the system is adopted.

4) 10kv basement is humid in the rainy season, and it is stipulated to turn on the heater in July and September to drive away the moisture.

5) Cold-proof: Outdoor equipment, such as SF6 circuit breaker, has a low SF6 density at low temperatures, so it is stipulated that the heater should be turned on in December and February to heat up.

6) Lightning protection: install an isolation transformer on the communication line between the telecontrol box and the dispatcher.

Substation Operation and Maintenance" is a book published by the Machinery Industry Press, which can be used as a training material for high-voltage electricians to enter the network, and can also be used as a skill training material and daily learning skills textbook for substation operation electricians.

This book is based on the State Grid Corporation's "Electric Power Safety Work Regulations (Substation Part)", Hebei South Power Grid Substation Operation Regulations, Substation Operation Regulations, Substation Job Specifications and the requirements of substation operation attendant assessment and training, combined with the unique characteristics and actual needs of metallurgical enterprise substation operation.

There are five chapters in the book. The first part is the basic knowledge of the profession, which introduces the basic knowledge of the power system. The second part is the operation and maintenance of substation, which introduces the operation and maintenance of primary and secondary equipment of substation.

The third part is the operation and accident handling of the substation. The fourth part is the management and operation of substations, including various systems required for the operation and management of substations, and substation safety management. The fifth part is the operation and dispatch of the enterprise power grid, introducing the operation of the internal power grid of the enterprise and the handling of common power grid accidents.

This book can be used as a training material for high-voltage electricians to enter the network, and can also be used as a skill training material and daily learning skills textbook for electricians in substation operation. At the same time, it can also be applied to electric power vocational and technical schools, colleges and universities electrical professional practical skills training, electrical engineer technical training application books.
