Description

Technical Field

[0001] The utility model relates to the field of busbar bridge compensation, in particular to a busbar bridge housing with a telescopic compensation function. Background Art

[0002] The busbar bridge, also known as the bridge connection, is the main connection between the high (low) voltage cabinet and the high (low) voltage cabinet or between the transformer and the high (low) voltage cabinet.

[0003] When the distance between two sets of devices to be connected is relatively long, during the actual installation process, errors may cause a certain error between the last busbar bridge and the electrical equipment, making it too long or too short. When it is too long, the excessive part can generally be cut off by cutting. When it is too short, a busbar bridge of appropriate length is generally cut first and then welded to the last busbar bridge to compensate for the length. This method is more complicated and less efficient during actual operation. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 4In an embodiment of the utility model, a busbar bridge housing with a telescopic compensation function includes a busbar bridge 1, and a compensation mechanism is installed on the inner wall of the butt end of the two busbar bridges 1. The two sides of the compensation mechanism are detachably connected with a No. 1 fixing bolt 3. A slot 5 for the No. 1 fixing bolt 3 to slide is provided on the two side plates of the busbar bridge 1. The outer wall of the No. 1 fixing bolt 3 is located on the outside of the busbar bridge 1 and is threadedly connected with a tightening bolt 4 at one end; the compensation mechanism includes a telescopic box 2 and an installation cover 7. The top and both sides of the telescopic box 2 are open structures. The installation cover 7 is slidably installed at the top opening position of the telescopic box 2. The slidably installed installation cover 7 is fixedly connected to a busbar bridge 1 through a fixing mechanism.

[0020] In this embodiment, during the installation of the busbar bridge 1, if there is still some distance between the busbar bridge 1 and the electrical equipment, but the distance is small, a compensation mechanism is installed between the two busbar bridges 1 at the end. The compensation mechanism is used to make up for the missing distance, eliminating the need for cutting or welding to compensate for the length of the busbar bridge 1 at the end.

[0021] Place the telescopic box 2 of the compensation mechanism at the docking position of the two busbar bridges 1, then fix the telescopic box 2, and then lay the busbar. After the busbar is laid, slide the installation cover 7 on the top of the telescopic box 2. After the installation cover 7 is slid and installed, install and fix the installation cover 7 through the fixing mechanism.

[0022] Please refer to Figure 3 and Figure 4 The compensation mechanism also includes a track 12 welded to both sides of the inner wall of the telescopic box 2. The inner wall of the track 12 is slidably connected with a slider 11. One end of the slider 11 passes through the outside of the track 12 and is bent upward. The top of the upward bent portion of the slider 11 is integrally formed with the bottom end of the mounting cover 7. The mounting cover 7 is integrally formed with a downwardly bent limit plate 8. The limit plate 8 is used to limit the maximum sliding distance of the mounting cover 7.

[0023] In this embodiment: when sliding and assembling the mounting cover 7, the slider 11 is aligned with the inner cavity of the track 12, and then the mounting cover 7 is pushed to move. The mounting cover 7 drives the slider 11 to slide axially in the track 12 until the slider 11 and the track 12 completely overlap. At this time, the limit plate 8 is abutted against one end of the telescopic box 2, which can prevent the mounting cover 7 from excessive movement or sliding installation into place, and then the position of the mounting cover 7 is fixed using a fixing mechanism.

[0024] Please refer to Figure 2The fixing mechanism includes fixing ears 6 integrally formed on both sides of the bottom end of the No. 1 fixing bolt 3. A No. 1 through-hole is formed at the center of the fixing ear 6. A No. 2 through-hole is opened at the position where the busbar bridge 1 is aligned with the No. 1 through-hole. The No. 2 fixing bolt 9 passes through the No. 1 through-hole and the No. 2 through-hole and is threadedly connected to the fixing nut 10. The tightened fixing nut 10 is used to fix the position of the fixing ear 6.

[0025] In this embodiment: after the telescopic box 2 is fixed to the busbar bridge 1, a pistol drill is used to align with the No. 1 through-hole, and a No. 2 through-hole is drilled on the busbar bridge 1. Then, the No. 2 fixing bolt 9 is passed through the No. 1 through-hole and the No. 2 through-hole and is threadedly connected with the fixing nut 10. The fixing nut 10 is completely tightened. At this time, the position of the mounting cover 7 is fixed and cannot be moved.

[0026] Please refer to Figure 3 and Figure 4 The No. 1 fixing bolt 3 is located at one end of the inner wall of the telescopic box 2 and is integrally formed with an anti-slip portion. The telescopic box 2 is provided with a connecting circular hole that matches the No. 1 fixing bolt 3.

[0027] In this embodiment: after the positions of the telescopic box 2 and the two busbar bridges 1 are determined, the No. 1 fixing bolt 3 is inserted from the connecting circular hole into the slot 5, and then the tightening bolt 4 is used to connect with the No. 1 fixing bolt 3, and the tightening bolt 4 is rotated to lock it, so that the position of the telescopic box 2 can be fixed.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
