Shielding-type insulation detection structure

A shielding-type insulation detection structure, comprising:

• an input power source comprising a first terminal and a second terminal;
• a first shielding layer electrically connected with the first terminal of the input power source;
• a second shielding layer comprising a first sub-layer and a second sub-layer, wherein the first sub-layer and the second sub-layer are separated from each other;
• an insulation layer disposed between the first shielding layer and the second shielding layer;
• a first impedance unit electrically connected between the first sub-layer of the second shielding layer and the second terminal of the input power source;
• a second impedance unit electrically connected between the second sub-layer of the second shielding layer and the second terminal of the input power source;
• and
• a detection circuit electrically connected with the first sub-layer and the second sub-layer, wherein a detection signal related to a voltage difference between the first sub-layer and the second sub-layer is detected by the detection circuit.
