Abstract: In this paper, an improper operation is discussed when need to exit the multiple-shot reclosing equipment, that is, only disconnect the multiple-shot reclosing equipments’ clips, while two sets of multiple-shot reclosing equipment’s conversion switch QK is still on “single-phase” state. The effect of this improper operating way is analyzed in detail. If the failure happens, the reclosing equipment cannot trip three phases of a circuit-breaker then reclose, this will lead to open-phase operation. This paper can help the operating staff familiar with the process of multiple-shot reclosing action; properly operate the multiple-shot reclosing equipment’s clips. Improve the recognition of complying fully to the operating regulations.
