[0034] At present, the meter cabinet usually separates the transformer room and the electric energy meter room into two independent compartments, but such a design takes up more space and is not conducive to the miniaturization of the meter cabinet and the box-type substation. For this reason, in the related technology, the meter cabinet places the transformer and the electric energy meter in the same compartment, but this will cause the structure in the compartment to be too compact, which is not convenient for the maintenance of the transformer and the electric energy meter.

[0035] To this end, an embodiment of the present invention provides a metering cabinet 1000, specifically referring to the accompanying drawings of the specification. Figure 1-Figure 7 shown.
