Condition assessment method and device for an outdoor post-mounted vacuum switch

A condition assessment device for an outdoor post-mounted vacuum switch, comprising:

• a model establishment module, configured to establish a condition assessment mathematical model of the post-mounted vacuum switch, and obtain scores of condition indicators of the post-mounted vacuum switch;
• and
• a condition assessment module, configured to acquire a condition assessment score based on the condition assessment mathematical model of the post-mounted vacuum switch and the scores of the condition indicators of the post-mounted vacuum switch, so as to realize on-line monitoring of a health condition of the post-mounted vacuum switch and assess the health condition of the post-mounted vacuum switch;
• wherein the condition assessment mathematical model of the on-column vacuum switch is configured as follows:
