Description

Technical Field

[0001] This utility model belongs to the field of ring main unit technology, and specifically relates to a combined ring main unit. Background Technology

[0002] A ring main unit (RNU) is an electrical device consisting of a set of power transmission and distribution equipment housed in a metal or non-metal insulated cabinet or assembled into a modular ring network power supply unit. When installing a RNU outdoors, a mounting base must be erected outdoors before installation, and a mounting compartment must be reserved for the RNU. However, due to errors in construction, mismatches may occur between the RNU and the mounting compartment when the RNU is installed on the outdoor mounting base. When the mounting compartment is large, workers can reduce the instability caused by the large size of the mounting compartment by adding filler to the edge area. However, when the mounting compartment is small, the construction workers need to enlarge the mounting compartment, which is inconvenient. Utility Model Content

[0019] Please see Figures 1-5 The present invention provides the following technical solution: a combined ring main unit, comprising symmetrically arranged connecting support plates 1, with a first connecting top plate 11 and a second connecting top plate 111 symmetrically fixedly connected to the inner sides of the two connecting support plates 1 respectively, and one end of the second connecting top plate 111 slidably connected to the interior of the first connecting top plate 11, a first connecting side plate 12 fixedly connected between the two symmetrically arranged first connecting top plates 11, and a second connecting side plate 121 fixedly connected between the two symmetrically arranged second connecting top plates 111, and one end of the second connecting side plate 121 slidably connected to the interior of the first connecting side plate 12, and a plurality of connecting slide rails 3 fixedly connected to one side of both the first connecting top plate 11 and the second connecting top plate 111, and mounting plates 31 slidably connected to the plurality of connecting slide rails 3.

[0020] In this implementation scheme: the symmetrically arranged connecting support plates 1 serve as side plates in the entire ring main unit, and also provide a connecting carrier for the first connecting top plate 11, the first connecting side plate 12, the second connecting top plate 111, and the first mounting groove 112. The first connecting top plate 11, in cooperation with the first connecting side plate 12, forms the top plate assembly and bottom plate assembly of the entire ring main unit. The second connecting top plate 111, in cooperation with the first mounting groove 112, forms the adjustable side plate assembly of the entire ring main unit. Thus, the first connecting top plate 11, the first connecting side plate 12, the second connecting top plate 111, and the first mounting groove 112 together form the adjusting assembly of the entire ring main unit. The first connecting top plate 11 and the first connecting side plate 12 respectively provide a connecting carrier for the second connecting top plate 111 and the first mounting groove 112 during the assembly of the entire ring main unit in the construction area. In this system, the overall width of the entire ring main unit can be adjusted according to the reserved installation slots in the construction area, so that the ring main unit can be well assembled and fixed with the reserved installation seats during assembly. This avoids the need for workers to reinstall the reserved installation seats or adjust the ring main unit due to dimensional errors between the ring main unit and the installation seats during construction, which facilitates the construction work and helps to improve the work efficiency of the workers. The connecting slide rail 3 located in the first connecting top plate 11 and the second connecting top plate 111 is used to provide the connection for the installation of various working components inside the ring main unit. The mounting plate 31 is used to provide a sliding connection carrier between the connecting slide rail 3 and the second connecting top plate 111 and the second connecting side plate 121. The connecting slide rail 3 can be easily adjusted to accommodate the overall width of the ring main unit by sliding. In addition, an inspection door is installed on one side of one of the connecting support plates 1.

[0021] The first connecting top plate 11 has a first mounting groove 112 inside, and one end of the second connecting top plate 111 is damped and slidably connected to the inside of the first mounting groove 112; wherein the first mounting groove 112 is used to provide space for the installation and storage of the end of the first connecting side plate 12.

[0022] The first connecting side plate 12 has a second mounting groove 122 inside, and one side of the second connecting side plate 121 is damped and slidably connected to the inside of the second mounting groove 122; wherein the second mounting groove 122 is used to provide space for installation and storage of the end of the second connecting side plate 121.

[0023] Support rods 2 are symmetrically fixedly connected to one side of the connecting support plate 1 and one side of the connecting support plate 1, and the support rods 2 are slidably connected to the outside of the support rods 2. Elastic rubber walls 21 are fixedly connected between the symmetrically arranged support rods 2. The support rods 2, with the cooperation of the elastic rubber walls 21, form a sealing assembly that fills the gap between the first connecting side plate 12 and the second connecting side plate 121. The elastic rubber walls 21 play a supporting role and also serve as a carrier for connecting the elastic rubber walls 21. The top of the elastic rubber walls 21 is connected to the first connecting side plate 12.

[0024] A mounting bracket 4 is fixedly connected to one side of the first connecting top plate 11, and a plurality of second limiting screws 41 are threadedly connected to the mounting bracket 4; wherein the mounting bracket 4 is used to provide a carrier for connecting the second limiting screws 41, and among the plurality of second limiting screws 41, the ends of the second limiting screws 41 located at the top and bottom penetrate into the interior of the first mounting groove 112, and the ends of the plurality of second limiting screws 41 located in the middle area penetrate into the interior of the second mounting groove 122.

[0025] The mounting plate 31 is threaded with a plurality of first limiting screws 32, and the first limiting screws 32 are located on one side of the mounting plate 31; wherein the first limiting screws 32 are used to limit the position of the mounting plate 31 on the connecting slide rail 3.

[0026] The working principle and usage process of this utility model are as follows: When installing the ring main unit outdoors, firstly, the overall width of the ring main unit is finely adjusted according to the width of the reserved mounting base in the outdoor construction area. While finely adjusting the overall width of the ring main unit, the second limiting screw 41 on the mounting frame 4 is loosened, and then the second connecting side plate 121 is pulled to adjust the overall width of the entire ring main unit. After the adjustment is completed, the second limiting screw 41 is tightened again, and the position of the mounting plate 31 is adjusted according to the overall width of the entire cabinet and limited by the first limiting screw 32. Then, the various internal components are installed inside the entire cabinet. In addition, during construction, the various working components can be installed inside the cabinet first and then the entire ring main unit is fixed.
