Moreover, when the outer wall temperature of the heat dissipating fin 3 is high, the nozzle 11 sprays water to cool the surface of the heat dissipating fin 3. When the transformer body 2 is protected, the fixing bar 38 connected to one end of the protection net 37 is pulled to move the L-shaped block 39 set at the top and bottom of the fixing bar 38 to engage with the L-shaped seat 40 set on the inner top and bottom surfaces of the other side of the other support frame 8. Thereby, the protective net 37 is fixed to protect the transformer body 2 and prevent outsiders from approaching the transformer body 2 and causing danger. When the staff needs to dismantle the protective net 37 for maintenance of the transformer body 2, the L-shaped blocks 39 at the top and bottom of the fixing bar 38 are disengaged from the L-shaped holder 40, and then the second motor 36 is driven to drive the winding roller 35 to rotate, so that the winding roller 35 rotates to reel up the protective net 37, thereby facilitating the staff to maintain the transformer body 2, and there is no need to dismantle the traditional guardrail before maintenance, which improves convenience.
