The utility model relates to a transformer substation for live working crawler -type from elevating gear that walks, including insulating crawler -type walking structure, be provided with on the crawler -type walking structure can go up and down, and insulating scissors fork type lifting structure, can be provided with the work fill structure that is used for operating personnel to stand scissors fork type lifting structure on with sliding, be provided with a plurality of abilities on the crawler -type walking structure and stretch out crawler -type walking structure, and can stretch out and draw back and change high bearing structure around the corresponding vertical rotation of axes, being provided with the ladder stand structure extension that makes progress, just insulation on the crawler -type walking structure. The device overcomes that the too big inconvenience of appearance that prior art exists gets into the transformer substation or the bearing is little, the poor stability scheduling problem, has satisfied the demand of the electrified operation of ascending a height of 220kV and following electric pressure transformer substation.
