Abstract:
With the continuous expansion of power grid capacity and the development of smart grid,higher requirements are put forward for the reliability and safety of power supply.The performance of low voltage switching devices and the coordination between various switching devices are closely related to the reliability of power system.Starting from improving the reliability requirements of power system control and protection functions,the present situation,technical requirements and shortcomings of electromagnetic apparatus commonly used in the main circuit of low voltage distribution network such as contactors and circuit breakers are expounded,and the necessity of the development of integration technology of low voltage electromagnetic apparatus is pointed out.The research status of the new principle structure technology at home and abroad and three realization forms of this technology are summarized.The necessary intelligent control technology in the integrattion process is analyzed,including fault identification and optimal control of motion process.Finally,the trend of low voltage electromagnetic apparatus integration technology is discussed.
