Description

Technical Field

[0001] The utility model relates to the technical field of ring network cabinets, in particular to a high-voltage ring network cabinet which can be quickly repaired. Background Art

[0002] A ring main unit is a group of electrical equipment installed in a metal or non-metallic insulating cabinet or made into an assembled interval ring main unit. Its core part uses load switches and fuses. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety.

[0003] The existing ring network cabinet is directly fixed in the distribution cabinet by fasteners. When repairing the ring network cabinet, only the cabinet door on one side of the ring network cabinet needs to be opened for maintenance. During maintenance, the maintenance personnel need to squat and drill into the ring network cabinet to complete the maintenance, which is very inconvenient. At the same time, the cabinet door of the existing ring network cabinet is only provided on one side, and a handle is required to open it horizontally when opening it, which easily causes obstruction during maintenance.

[0012] Preferably, first limiting grooves are opened in the base near both sides of the middle seat, first limiting blocks are movably embedded in the first limiting grooves, and the first limiting blocks are welded to the middle seat.

[0013] Preferably, second limiting grooves are opened in the middle seat near the two sides of the top seat, second limiting blocks are movably engaged in the second limiting grooves, and the second limiting blocks are welded to the top seat.

[0014] Preferably, a protective shell is welded on a side of the fixing block away from the cabinet door, a push plate is movably engaged in the protective shell, and the push plate movably fits the fixing column.

[0015] Preferably, a first elastic member is provided on a side of the push plate away from the fixing column, and the first elastic member is movably fitted in the protective shell.

[0016] Preferably, limiting rods are welded on both sides of the top of the clamping ring, the limiting rods are movably embedded in the fixing block, and a second elastic member is movably attached to one side of the limiting rod close to the clamping ring.

[0017] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0018] First, pull the main body of the ring network cabinet, which drives the top seat to move, and the top seat slides on the middle seat through the second roller until the top seat drives the middle seat to move through the second limit blocks on both sides, and the middle seat slides on the base through the first roller at the bottom, thereby pulling the main body of the ring network cabinet out of the distribution box, which is convenient for multi-angle inspection of the main body of the ring network cabinet.

[0019] Second, twist the knob, and the knob drives the rotating block to rotate in the rotating groove. The rotating block pushes the snap ring, so that the snap ring compresses the second elastic member through the limit rod and moves downward until the snap ring is no longer engaged with the snap groove. At this time, the first elastic member can push the fixed column through its own elastic force, so that the fixed column is separated from the fixed block and drives the cabinet door to rotate. After the fixed column is separated from the fixed block, the snap ring will be reset under the action of the second elastic member, so that the cabinet door can be opened quickly, thereby improving the efficiency of maintenance.
