Description

Technical Field

[0001] This invention relates to the field of distribution cabinet technology, and more specifically, to a variable-capacity low-voltage distribution cabinet and its adjustment method. Background Technology

[0002] Low-voltage switchgear and control equipment, commonly known as low-voltage switch cabinets or low-voltage distribution cabinets, refers to complete sets of electrical installations with AC and DC voltages below 1000V. In traditional distribution cabinets, the internal space layout is fixed, which limits the versatility of the distribution cabinet during use. Existing publicly available variable volume structures are usually achieved by adjusting the position of internal partitions by removing screws, which also has significant limitations on the adjustable volume. There is a need for a more reasonable and less restrictive variable volume low-voltage distribution cabinet and its adjustment method. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a variable volume low-voltage switchgear and its adjustment method, in view of the above-mentioned defects of the prior art.

A first transverse slot is provided at the bottom of the insulating partition. Multiple parallel longitudinal second slots are provided on the insulating partition, with the lower ends of the second slots communicating with the first slots. The width of the first slot is the same as the width of the second slot. Multiple transverse movable rods and multiple detachably connected mounting base plates for mounting switching devices are provided on the insulating partition. One end of each movable rod has an annular groove that mates with a second slot. The end of the movable rod is threadedly fitted with a threaded sleeve that abuts against the insulating partition for position locking. Initially, the end of the movable rod with the annular groove is located within the first slot. Three support plates and three locking units are longitudinally rotatably connected to the movable rods, each corresponding to one of the support plates and locking their positions after rotation. After the three locking units lock the support plates, the orientation of the support plates is sequentially left, upward, and right.

[0006] The variable-capacity low-voltage distribution cabinet of the present invention is provided with slide rails that slidably connect the insulating partition at the top and bottom of the cabinet body; and a transverse moving unit that drives the insulating partition to move back and forth is provided at the bottom of the cabinet body.

[0008] The variable volume low-voltage distribution cabinet of the present invention includes a traverse unit comprising a lead screw that moves the insulating partition and a lead screw motor that drives the lead screw.

[0015] After adjusting the height of the movable rod, tighten the threaded sleeve on the movable rod to fix its position.

[0016] The required number and angle of support plates are unfolded, and the angle of the unfolded support plates is fixed by the locking unit. If there are support plates that do not need to be unfolded, the support plates that do not need to be unfolded are rotated to the upper surface of the horizontal support plates that are fitted and fixed.

[0017] As needed, the base plate is fixedly installed on the insulating partition to complete the volume adjustment operation.
