Abstract

A shielding-type insulation detection structure (1, 1a) includes an input power source (2, 2a), a first shielding layer (3), a second shielding layer (4), a first impedance unit (6), a second impedance unit (7) and a detection circuit (8). The first shielding layer (3) is electrically connected with a first terminal (21) of the input power source (2, 2a). The second shielding layer (4) includes a first sub-layer (41) and a second sub-layer (42). The insulation layer (5) is disposed between the first shielding layer (3) and the second shielding layer (4). The first impedance unit (6) is electrically connected between the first sub-layer (41) and a second terminal (22) of the input power source (2, 2a). The second impedance unit (7) is electrically connected between the second sub-layer (42) and the second terminal (22) of the input power source (2, 2a). The detection circuit (8) is used to detect a detection signal related to a voltage difference between the first sub-layer (41) and the second sub-layer (42) of the second shielding layer (4).
