Fig. 1 is the utility model modular structure schematic diagram;
Fig. 2 is the utility model external structure schematic diagram;
Fig. 3 is the utility model back structures schematic diagram;
Fig. 4 is the utility model side structure schematic diagram.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Figure 1-3, general digital electric protection device of the present utility model comprises set of circuits plate 1, described circuit board 1 comprises an embedded controller 2, embedded controller 2 is connected with signal acquisition module 3, described signal acquisition module 3 is connected with signal input terminal 4, described embedded controller 2 is connected with load module 5, display module 6 and control signal lead-out terminal 7, described circuit board 1 is located in a metal cabinet 8 closed, described casing 8 comprises a panel 81 and is located at the housing 82 at panel rear, housing 82 is made up of rear end face 821 and side plate 822, described load module 5 and display module 6 are located on panel 81, described signal input terminal 4 and control signal lead-out terminal 7 are located on the rear end face of housing.
On the design area of panel, in the present embodiment, the length of described panel 81 is 122.54mm ± 0.01mm; 75.5mm ± the 0.01mm of width.
