The invention provides an electromagnetic detection device and method for PCCP broken wires, and belongs to the technical field of PCCP broken wire detection. The device comprises a sleeve; the exciting coil is arranged in the sleeve and used for exciting current in the metal net of the PCCP; the thermal imager is arranged on one side of the sleeve and used for detecting the position, with the temperature exceeding a threshold value, in the metal net of the PCCP as the wire breaking position of the PCCP after the exciting coil excites current in the metal net of the PCCP. The thermal imager circumferentially rotates around the center of the sleeve through the rotating mechanism; the moving mechanism is arranged on the sleeve and used for driving the sleeve to axially move in the PCCP. The method can accurately detect the wire breaking position of the metal net of the PCCP. 本发明提供了一种用于PCCP管道断丝的电磁检测装置及方法，属于PCCP管道断丝检测技术领域。该装置包括：套筒；激励线圈设于套筒中，用于在PCCP管道的金属网中激发电流；热成像仪设于套筒一侧，用于在激励线圈在PCCP管道的金属网中激发电流后，探测PCCP管道的金属网中温度超过阈
