Electrical equipment is an indispensable part of power system. Inner Mongolia Power Maintenance The condition of the machine is related to the stable operation of the power grid, so the inspection, detection and predictive maintenance of electrical equipment is an important way to ensure the safety of equipment and the stable operation of the power grid.
With the continuous development of power grid capacity, the number of mechanical equipment is gradually increasing, and the traditional management and maintenance technology can no longer meet the requirements. How to correctly grasp the status of equipment, improve maintenance efficiency, reduce maintenance costs, and improve the service life of equipment is the current difficulty.
(1) Maintenance of electrical equipment
Inner Mongolia power maintenance equipment The development trend of maintenance mode can be divided into three stages: common fault maintenance timely maintenance condition based maintenance.
In the development process of power industry, the maintenance and management mode of electrical equipment has also changed. At the initial stage of its development, the maintenance management is dominated by the maintenance method of common faults; By the middle and late 1920s, the timely maintenance of the scheme was dominant; After joining the 21st century, the scale of power grid business has expanded rapidly. Due to the weakness of timely program maintenance methods, not only some maintenance resources are consumed, but also some machines are "out of repair for a long time" due to insufficient maintenance manpower, and condition based maintenance is gradually emerging.
Condition based maintenance is a countermeasure for allocation and maintenance according to the health status of equipment after testing. This maintenance method started from the equipment maintenance of four axle aircraft in foreign aerospace industry in the 1960s. In 1978, it was gradually widely used in equipment maintenance of foreign naval warships. In the 1980s, it was also applied and promoted in China's nuclear industry, and rapidly developed into the maintenance of power engineering equipment in the power industry.
Condition maintenance is extremely important: first, in the past, due to the lack of scientific and reasonable evaluation standards and methods, coupled with the limited accumulation of materials, the grasp of system health awareness was neither perfect nor good. More system software can classify equipment status more accurately, comprehensively and systematically;
Secondly, because the system health awareness is accurate, comprehensive and the system software is mastered after the situation review, the purpose of equipment maintenance is greatly improved;
Again, Inner Mongolia Power Maintenance It can greatly reduce the workload of the original maintenance method, improve the maintenance quality and the health awareness of mechanical equipment, and lay the foundation for the whole life cycle management of the property of the power grid company.
