Industry Overview:

Electric power equipment is based on electromagnetic principle of generators, transformers, current transformers, voltage transformers and so on, these power equipment in the operation process of electricity, heat, mechanical load, as well as the impact of the natural environment, long-term work will cause aging, fatigue, wear, so that the reliability of gradually reduced. In particular, once the insulating medium of the equipment is damaged, it cannot be automatically restored and has to quit operation. Therefore, necessary monitoring of power equipment to ensure its stable operation is of great significance to the reliability and security of power system operation.

According to the statistical data of American Electric Power Research Institute and Construction Code Association, the implementation of state monitoring and fault diagnosis of electric power equipment can improve the utilization rate of equipment by 2%~10%, prolong the service life by 10%~15%, and save the maintenance cost by 25%~30%. The state monitoring of electric power equipment not only ensures its reliable operation, Moreover, it can bring huge economic and social benefits to power equipment enterprises. Taking shengli oilfield power plant as an example, since 1998, dynamic balance has been carried out on the spot for 107 times by using the data mining equipment, and leakage in the vacuum system of steam turbine has been checked for 28 times, and many leakage points have been found. This not only extends the service life of the equipment, but also completely changes the past practice of inviting people to do dynamic balance and leak detection, saving more than 1.2 million yuan for the enterprise.

In recent years, with the continuous development of sensor and the on-line monitoring technology and mature, and the condition monitoring technology in our country in recent years has been widely used in power system, so as to improve equipment utilization, lower equipment accident rate, so the state overhaul alternative preventive maintenance has been accepted by electric power system and identity, and become the inevitable trend of equipment maintenance.
