The present application discloses a multifunctional low-voltage metering cabinet, including a metering cabinet body. The metering cabinet body is provided therein with a plurality of separating plates. The plurality of separating plates divide the metering cabinet body into a plurality of independent metering chambers. The plurality of metering chambers are provided with lead seal brackets and concealed hinges. The metering chamber provided with measuring meters is also provided with an observation window. The observation window is disposed on the door of the corresponding metering chamber. Through the four edges of the observation window, all measuring meters in the metering chamber corresponding to the observation window can be observed. The conventional metering cabinet space is dividedinto multiple independent metering chambers which maintain independent structures and are functionally connected to each other. The multifunctional low-voltage metering cabinet can be matched with various wiring scheme cabinets. Moreover, the installation of the lead seal brackets and the concealed hinges guarantees the safety of each metering chamber. The installation of the observation window facilitates the observation of the measuring meters, thereby realizing the versatility and applicability of the measuring meters.
