Through analyzing an incorrect closing accident of 500 kV breaker, deep and detailed introduction of starting and blocking circuit of recloser device is given in paper. And incorrect closing reason is analyzed in two aspects of breaker mechanism and protective installation. In terms of local situation, a simple and applied improved scheme is proposed. The scheme can avoid the same accident, which is a good reference to the same type equipment.
