The invention discloses a dissimilar metal electrical isolation monitoring device. The device comprises a main cabinet and at least one junction box, wherein a voltage detection module, an insulationresistance detection module, a setting value module, a search generator module, a detection control module and a power module are arranged in the main cabinet; the voltage detection module is used fordetecting an electrode voltage difference between dissimilar metal; the setting value module is used for setting a voltage setting value; the detection control module is used for comparing the electrode voltage difference and the voltage setting value to judge the electrical isolation state of the dissimilar metal; the insulation resistance detection module is used for detecting isolation resistance between the dissimilar metal; and the search generator module is used for outputting an alternating current to a detected channel when the insulation resistance detection module detects the isolation resistance between the
