Photovoltaic power generation box transformer substation high-voltage cabinet locking device

The utility model relates to a locking device for a high-voltage cabinet of a photovoltaic power generation box transformer substation, and relates to the field of pulling mechanisms. Comprising a limiting barrier plate, a cabinet door mounting plate and a mechanical locking plate, the limiting barrier plate is arranged between the cabinet door mounting plate and the mechanical locking plate, the limiting barrier plate is parallel to the cabinet door mounting plate, the mechanical locking plate is perpendicular to the limiting barrier plate, a mechanical locking hole is formed in the mechanical locking plate, and the limiting barrier plate is arranged in the mechanical locking hole. The aperture of the mechanical locking hole is not smaller than the diameter of the lock rod, and the cabinet door installation plate is provided with an installation screw hole. According to the scheme, the technical problem of how to improve the safety performance of the high-voltage cabinet is solved, and the five-prevention sa
