Use front expansion: side the utility model being moved to totally-enclosed bus bar canister, by the strength of metallic support rod, collapsible bridge part is stretched to both sides, makes it launch completely; Tilt across ladder, make one end bay ladder leg be cross over bus bar canister opposite side.
Use rear folding: tilt across ladder, make its two legs be cross over bus bar canister the same side, by the strength of metallic support rod, upwards push away collapsible metallic support transverse slat, make it completely folding.
2. double-bus discharges (see Fig. 6 part B) up and down side by side:
Use front expansion: side the utility model being moved to totally-enclosed bus bar canister, by the strength of metallic support rod, collapsible bridge part is stretched to both sides, makes it launch completely; Tilt across ladder, make one end bay ladder leg be cross over bus bar canister opposite side.Then, height as required, connects adjacent two by rotational communication valve and makes it lengthen afterwards in steady status across terraced single-unit.
Use rear folding: tilt across ladder, make its two legs be cross over bus bar canister the same side.Disassembled lengthened below across terraced single-unit by rotational communication valve; Inwardly push away the collapsible metallic support transverse slat of bridge plate bottom, inwardly push away collapsible bridge both sides simultaneously, make it completely folding.
3. single busbar connection (see Fig. 6 C part):
Occupation mode with situation 1..
Launch before use of the present utility model to make an inspection tour in operation maintenance personnel or carry out in preoperative preparation.Convert mode and the position of expansion according to bus bar canister disposing way in operating process.
The utility model can make operation maintenance personnel directly pass through bus bar canister very easily, need not detour back and forth and flog a dead horse, thus decrease the operating time of operation maintenance, reduce working strength, provide the reliability of supply line from bus bar canister two ends.
The utility model is that universal transformer station fully closed combined electric unit bus bar canister is across ladder, bridge part and all can adjusting according to length with highly across ladder part, height-adjustable, width are scalable, meet the pose pattern that bus bar canister is all, applied widely, be easy to promotion and implementation.
