Summary:The invention provides a plug-in intermediate relay voltage class locking device and a locking method. The device comprises a relay body, a base and a locking mechanism, wherein the locking mechanismsare respectively arranged at the bottom of the relay body and an upper part of the base, the locking mechanism comprises a plurality of grooves and connecting plugs arranged in the grooves, breakinglines are arranged at the joints of the connecting plugs and the grooves, the connecting plugs can be broken off along the breaking lines to be exposed out of the grooves, and different locking codingmethods are formed by arranging different grooves and connecting plugs. According to the device, different mechanical codes are correspondingly arranged for plug-in relay bodies and bases with different voltage levels for locking, the relay bodies and the bases can be reliably engaged after being inserted, locking is achieved, only the same voltage class can be matched and inserted, so the situation that equipment cannot r
