Therefore, the compressed air supplied by the compressed air supply means 300 is supplied only to the space between the control panel 110 and the cover 200. When compressed air is supplied to the space between the control panel 110 and the cover 200 as described above, the water introduced into the space between the control panel 110 and the cover 200 has a water level sensing unit having a lower water level ( Until it is lower than 400).

That is, the water level of the water flowing into the space between the control panel 110 and the cover 200 does not rise above the water level shown in FIG. 8, the water side mounted in the water transformer unit case 100. The electric machine will not be submerged.

In addition, when more water is introduced into the water substation facility system than the state shown in FIG. 8 and the water level rises to the water level detecting unit 400 located on the upper side as shown in FIG. The float 430 of the water level detection unit 400 is all floated, the compressed air supplied by the compressed air supply means 300 and the space between the control panel 110 and the cover 200 and the compressed air supply means All are supplied into the case 4.

Therefore, even if the entire water substation installation system is submerged in water, the space level between the control panel 110 and the cover 200 and the level inside the compressed air supply means case 4 do not rise above the level shown in FIG. 9. Therefore, both the water transformer and the compressed air supply means 300 mounted in the water transformer case 100 are not flooded.

10 is a cross-sectional view of the second embodiment of the water level detection unit 400 included in the water substation facility system according to the present invention.

In addition, the water level detecting unit 400 applied to the water substation facility system according to the present invention is configured to open and close the compressed air discharge line 420 by buoyancy of the knitting 430 as shown in FIGS. 5 and 6. As shown in FIG. 10, a separate switch 470 may be pressed by the buoyancy of the knitting 430.
