With the rapid development of China's national economy, the GDP is also increasing, which can also show that the scale of China's industrial enterprises is gradually expanding, and the internal structure of the power system is also gradually improving. In the operation of high-voltage electrical equipment, how to prevent the high-voltage electrical equipment from stopping operation due to failure is an important problem that all staff need to think about. Based on the development of industrial electrical equipment, this paper analyzes the measures that should be taken in the maintenance and inspection of electrical equipment, so as to promote the rapid development of enterprises.
The production and operation of all kinds of factories in China mainly depend on the cooperation of all kinds of large electrical equipment and mechanical equipment. Due to the different types and quality of electrical equipment, the maintenance and management of electrical equipment is a more professional and complex work. In the actual operation process, the maintenance of electrical equipment will be more complex, electrical maintenance management personnel need to master professional electrical knowledge, enough to understand the situation of electrical equipment, so as to make the maintenance work to achieve a reasonable, scientific and clear goal, and promote the improvement of high-voltage electrical equipment maintenance process.
The equipment in the high voltage distribution system includes fittings, supporting insulator, bus, lightning arrester, voltage transformer, current transformer, isolating switch, high voltage switch, etc. In the normal operation of the system, these system equipment should run smoothly to complete the distribution task. Perfect maintenance can ensure the normal operation of high-voltage distribution system. The main maintenance requirements are as follows: first, SCADA data monitoring and acquisition should be completed through operation and maintenance, so as to ensure that the operation parameters of distribution system can reach the established constraints of normal state; Secondly, DSM and LM are implemented through maintenance to improve the load curve under normal state, so as to avoid the situation that excessive load causes violation of inequality constraints when it reaches the peak value; DMS can reduce network loss through voltage / reactive power optimization and load balance under normal state through implementation maintenance, so as to promote the smooth operation of distribution system. Then, after maintenance, the mechanical calculation is completed in different stress states and meteorological conditions. The safety factor should not be lower than the specified value to avoid safety accidents. In the normal operation of high-voltage distribution system, the maintenance work needs to ensure that its design and implementation can maintain the normal work, and also can ensure the safety of the distribution system. In the actual distribution system maintenance, we also need to consider the normal operation of the system and make a reasonable and comprehensive maintenance plan.
