Summary:The present disclosure relates to a system for detecting a defective porous sheet. The system comprises a clamp with a through hole, a heating unit, a temperature sensor, a control unit, an air permeability determining unit and a judging unit. In this manner, it is possible to provide a novel system for detecting a porous sheet, which may be a defective separator after being coated with a porous coating, in advance by using the air permeability and shutdown temperature of the porous sheet itself. 本公开涉及一种用于检测有缺陷多孔片材的系统。该系统包括具有通孔的夹具、加热单元、温度传感器、控制单元、空气渗透率确定单元和判定单元。以这种方式，能够提供用于事先通过使用多孔片材本身的空气渗透率和关停温度来检测多孔片材的新颖系统，该多孔片材在被涂覆有多孔涂层之后可能是有缺陷分隔件。
