Panel processed, 8 smoke inductors, 9 control cabinets, 10 temperature inductors, 11 alarms, 12 transformers, 13 insulating layers, 14 springs.
Specific implementation mode
Fig. 1 is a kind of structural schematic diagram of dry-type power transformer protective device of the utility model, including protective cradle 1,
It is equipped with babinet 2 on the holder 1, transformer 12 is internally provided in the babinet 2, insulation is equipped in 12 bottom of the transformer
Layer 13, the insulating layer 13 is affixed by spring 14 with 2 interior bottom surface of babinet, and dry powder is equipped with right over the transformer 12
Slot 4 is equipped with valve positioner 3 in 4 lower part of dry powder slot, temperature inductor is respectively equipped in 2 inner surface side of the babinet
10, smoke inductor 8, box cover 5 is equipped on 4 top of dry powder slot, and control cabinet 9 is equipped in 2 outer surface side of the babinet,
It is equipped with control panel 7 in the control cabinet 9, temperature inductor 10, the smog with 2 inner surface of babinet respectively of the control panel 7
The valve positioner 3 of 4 lower part of inductor 8 and dry powder slot connects, and the control panel 7 and the alarm 11 of outer connection connect.
Fig. 2 is a kind of structural schematic diagram of dry-type power transformer protective device dry powder slot of the utility model, the dry powder
