Analysis of the electrical equipment repair status Paper Keywords: state of the reliability of regular maintenance Abstract: Power system equipment maintenance, long time period is based on regular maintenance of the system, but recently this simple time-based maintenance system has been regularly questioned, people are constantly adopting new technologies to explore reform maintenance system, and gradually to the state-based maintenance mode transition, and have achieved some results. 1 Introduction Electrical equipment reliability and power system security and stability are closely related. For a long time, China’s power industry has been based on electrical equipment preventive test the Statutes of the regular power electrical equipment testing, repair and maintenance of power system security operation plays a very important role as the state of maintenance technology is widely recognized, state of repair technology to replace regular maintenance has become inevitable. 2 the need to implement condition-based maintenance analysis With the reform of the power system and operating mechanism changes, and reduced to increase efficiency and further improve power supply reliability requirements, planned maintenance system has been gradually can not fully meet the requirements of development of the situation, so eager to achieve the electrical equipment maintenance and management by the ‘to the compulsory repair, maintenance mandatory good’ approach to ‘should be compulsory repair, maintenance mandatory good,’ the concept of change, and traditional equipment maintenance reforms. In fact, the state of maintenance of electrical equipment is currently in advanced industrial countries have generally adopted a scientific equipment maintenance and management strategies. Electricity from a planned economy to a market economy shift, economic and social benefits are an important goal to pursue, and to improve reliability and reduce cost of productio
