Abstract： [Purposes] In order to further improve the reliability of power supply，the measures and research directions to improve the reliability of switching operation of distribution network lines are discussed.[Methods] The trip event of a distribution network line is analyzed.The action process of the switch is identified by the protection message.The abnormal situation of the switch is demonstrated from the protection configuration principle，and the typical automatic switch protection function test is completed.[Findings] After analysis，it is found that the wide access of distributed power supply has many effects on the operation of the system，so it is necessary to study and strengthen the control;the function of distribution network device is not perfect，and the test work should be done well.[Conclusions] There are still many problems in the switch of the distribution network.For example，the external challenges are faced with the access of distributed power sources and the equipment itself may also have functional defects that are difficult to find.In the future，it is necessry to continue to study and solve measures to effectively improve the rapid recovery capacity of the distribution network.
