Further, a lead seal column is installed on the small door of the panel.

The utility model has the following effects:

The box structure is re-optimized, and the bottom box is divided into a power inlet switch room, a user metering room and a user outlet switch room. The three rooms have independent physical spaces, and the management requirements of the metering device are integrated into specific products. Through the structure Changes to achieve metering control of end users, to ensure that different personnel are managed according to their authority without interfering with each other.

Furthermore, the power inlet switch room, user metering room and user outlet switch room are all designed and equipped with protective wire grooves to optimize the wiring in the box, which solves the disadvantages of similar products and makes the product more scientific and reasonable.

Furthermore, lead seal columns are installed on the small door of the panel, and anti-unauthorized opening measures are installed on the box cover, and the installation requirements of seal and lock are met at the same time.

Furthermore, wire holes are reserved at different positions on the partition, and the unique built-in trough-type separate wire protection groove and wire holes not only ensure that the wires are not damaged, but also solve the eddy current generated by the wiring behind the box. The problem of heating the wires for a long time improves the aesthetics of the product.

The embedded panel structure not only solves the installation problem of different equipment heights, but also ensures the overall beauty and safety of the cabinet.
