Description

Technical Field

[0001] The utility model relates to the technical field of grid connection cabinets, in particular to a metering grid connection cabinet. Background Art

[0002] Existing grid connection cabinets are generally installed without being against the wall. A door body is hinged to the rear side of the grid connection cabinet, and a metering mounting plate is fixedly connected inside. After the grid connection cabinet is fixed at the required site, after opening the door body, the metering current transformer can be installed on the metering mounting beam at the rear side inside the grid connection cabinet (the specification requires that the metering current transformer be installed at the rear side inside the grid connection cabinet), and subsequent acceptance and maintenance can be carried out. However, when the grid connection cabinet is installed against the wall, the door body at the rear side of the grid connection cabinet cannot be opened, and it is impossible to install the metering current transformer and carry out subsequent acceptance and maintenance. Therefore, it is urgently necessary to design a metering grid connection cabinet that can be installed against the wall and can normally install the metering current transformer and carry out subsequent acceptance and maintenance, which becomes an urgent technical problem to be solved. Summary of the Utility Model

[0003] In order to overcome the existing technical defects, the purpose of the utility model is to provide a metering grid connection cabinet to solve the above technical problems.

A mounting plate for fixedly connecting secondary components through fasteners is fixedly connected to the front side of the inner door, and an insulator mounting beam for installing a metering current transformer is arranged in the rear electrical installation chamber.

[0006] Adopting the above technical solution, after the grid connection cabinet is installed against the wall, the current transformer can be installed on the insulator mounting beam in the rear electrical installation chamber after opening the outer door and the inner door on the cabinet body. When acceptance or maintenance is required, opening the outer door and the inner door on the cabinet body can carry out acceptance and maintenance on electrical components such as the current transformer in the rear electrical installation chamber, solving the technical problem that the existing grid connection cabinet cannot install the current transformer and carry out acceptance and maintenance after being installed against the wall; by fixedly connecting the mounting plate to the front side of the inner door, the secondary components that were originally installed in the front electrical installation chamber can be fixed through fasteners on the mounting plate, so that the overall external dimensions of the grid connection cabinet are the same as before, meeting the requirements for the external dimensions of the grid connection cabinet.

A first partition is provided between the first electrical installation chamber and the second electrical installation chamber, and a second partition is provided between the third electrical installation chamber. A cable channel penetrating through the first partition and the second partition is provided between the second electrical installation chamber and the third electrical installation chamber. By providing a plurality of wire inlet and outlet through holes, the design requirement of wire inlet from the bottom and outlet from the bottom can be achieved. By designing the cable channel, the wire can pass through the cable channel from the second electrical installation chamber into the third electrical installation chamber for wiring, meeting the wiring requirements.

[0009] In some embodiments, an inlet switch is installed on the lower door body, and an outlet switch is installed on the upper door body.

[0010] In some embodiments, an observation window is provided on the outer door.

[0011] In some embodiments, a wire passing hole for communicating the front electrical installation chamber and the rear electrical installation chamber is provided on the inner door.

[0012] In some embodiments, the left side of the inner door is hinged to a first mounting rod through a hinge, the first mounting rod is fixedly connected to the cabinet body, and a door lock cooperating with a locking member connected to a second mounting rod is fixedly connected to the right end of the inner door, and the second mounting rod is fixedly connected to the cabinet body.

[0013] In some embodiments, the material of the mounting plate is any one of PVC, PE, PP, PES, and PC, and the fastener is a self-tapping screw. Thus, the secondary components can be directly drilled and fixedly connected to the mounting plate through the self-tapping screw, and there is no need to pre-set threaded holes on the mounting plate.
