The utility model discloses further set up to cover and form the constant head tank for the face, form a plurality of pothooks around the constant head tank, the one end of pothook is fixed in one side of constant head tank, and the other end of pothook turns over to the constant head tank and turns over and forms the barb, one side of barb forms the inclined plane, the guard plate passes through the pothook to be fixed in the constant head tank.

When the protection plate is installed, the protection plate can be stably fixed in the positioning groove of the face cover by pressing down along the inclined plane of the barb, and the installation and the positioning are convenient.

The utility model discloses further set up to be provided with charactron and pilot lamp on the display panel, form rectangle groove and through-hole on the guard plate, the charactron is just to rectangle groove, and the pilot lamp is just to the through-hole.

The data and the state of charactron and pilot lamp can be seen through the guard plate by the user, so that the real-time data of electric power can be observed conveniently.

The utility model discloses further set up to the drain pan bottom and form the multirow grid, all be provided with the socket on power strip and the expansion board, the socket extends to outside the drain pan bottom.

Set up the grid on the above-mentioned drain pan in order to improve the heat-sinking capability of instrument, the plug seat directly passes the grid and extends to the drain pan bottom outside and form the wiring end in actual installation, makes things convenient for the wiring and the installation of digital display instrument.
