Description

Technical Field

[0001] The utility model relates to the technical field of ring network cabinets, in particular to a cabinet combining platform for ring network cabinets. Background Art

[0002] Ring main unit is generally divided into two types: air insulation and SF6 gas insulation. It is used to separate and connect load current, break short-circuit current and transformer no-load current, and the charging current of overhead lines and cable lines at a certain distance. It plays a control and protection role. It is an important switchgear for ring network power supply and terminal power supply. Ring main unit has the characteristics of compact structure, flexible operation, reliable interlocking, etc. It can provide satisfactory technical solutions for various application sites (especially places with harsh environments) and different user requirements. Ring main unit is suitable for small secondary substations, switchgear, box-type substations, residential areas, industrial and mining enterprises, large shopping malls, especially for airports, subways, railways and other places with high power requirements.

[0003] Common ring main unit cabinets are basically designed with two inputs and four outputs with PT, three gas box structures, and three sets of cabinets are connected together when the cabinets are connected; some ring main unit cabinets are mainly unit cabinets according to the technical specifications of various products, with two inputs and four outputs with PT, seven gas box structures, and seven sets of cabinets are connected together when the cabinets are connected. For outdoor ring main unit cabinets, the cabinets are connected by the supplier and then installed in the outdoor box. For indoor ring main unit cabinets, that is, the ring main unit cabinets used in the power distribution room, the supplier delivers them separately and connects the cabinets on site.

[0004] In the prior art, there are a variety of cabinet connection solutions for ring main units:

[0005] 1) Some manufacturers hoist the cabinets to be combined on the same ground, and use pneumatic guns to directly combine the two sets of cabinets together by lengthening bolts;

[0006] 2) For example, in a ring main unit assembly platform disclosed in Chinese patent CN210926833U, rails are provided at the front and rear ends of the upper end of the base, and the rails are welded and fixed to the base, a pulley assembly is provided at the upper end of the rail, and the pulley assembly is slidably connected to the rail, eight pulley assemblies are provided, and the pulley assemblies are provided in two groups, and a cabinet assembly flat plate is provided at the upper end of each group of pulley assemblies.

[0007] 3) As disclosed in Chinese patent CN218569674U, a ring main unit combining device comprises: a combining frame; an bakelite board slidably arranged on the combining frame, one ring main unit is placed on each bakelite board; a reciprocating mechanical driving member fixedly installed at one end of the combining frame, for pushing the ring main unit; a limiting member arranged above the combining frame and opposite to the reciprocating mechanical driving member, for providing a force on the ring main unit toward one side of the reciprocating mechanical driving member when combining the cabinets.

[0008] The technologies involved in the above cabinet combination scheme have obvious disadvantages, which are:

[0009] 1) If the cabinets to be combined are hoisted on the same ground, due to the uneven ground, there is a lack of a certain reference surface when combining the cabinets. The two sets of cabinets are directly combined together by lengthening the bolts with a jackhammer. This may damage the busbar connector used for combining the cabinets, damage the side expansion busbar socket, and there will be gaps between the cabinets after combining the cabinets, which does not meet the IP protection level;

[0010] 2) Chinese patent CN210926833U discloses a ring main unit assembly platform. After the platform is installed, the center of gravity of the ring main unit is difficult to grasp. When hoisting by ceiling hanging, how can the rear side of the ring main unit be controlled to be completely close to the limit boss on the assembly plate, and the two sides of the cabinet are completely aligned with the two sides of the assembly platform? If the cabinet on the assembly plate is misaligned front and back and the two sides cannot be aligned with the assembly plate, there is no way to adjust it. In addition, the ring network cabinet is not only a unit cabinet, but also a shared cabinet, including the unit cabinet body width is also inconsistent, such as the cabinet width dimensions are 360mm, 375mm, 420mm, 450mm, 500mm and other dimensions, there are a variety of schemes for combining shared cabinets, the shared cabinet dimensions of each combination scheme will be inconsistent, the cabinet flat plate needs to be designed according to the actual cabinet width dimensions, there will be countless, when the cabinets are combined, the cabinet combination personnel need to verify the width of the ring network cabinet, and then select the cabinet flat plate corresponding to the size, and then place the cabinet flat plate on the pulley assembly, which is too complicated and will increase countless workloads, seriously affecting the efficiency of cabinet combination.

[0011] 3) For example, a ring main unit merging device disclosed in Chinese patent CN218569674U uses mechanical hydraulic equipment to replace manual operation. However, like the patent CN210926833U, the ring main unit needs to be placed on a bakelite board, and the ring main unit cannot be placed straight by hanging from the ceiling. At the same time, countless bakelite boards of different specifications are also required, which will increase the workload and seriously affect the efficiency of merging. In addition, a hydraulic device is used as a driving component to push the ring main unit, but once the ring main unit merging component is deformed, misaligned, or other faults occur, the force pushing the ring main unit cannot be controlled, and the cabinets will continue to be merged even if there is a problem, which may cause the two cabinets to be merged to be completely damaged.

[0012] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
