Technical Field

[0001] This utility model relates to the field of switch cabinet technology, specifically to a contact box for switchgear. Background Technology

[0002] In power systems, switchgear is a crucial component, responsible for opening and closing circuits to ensure stable operation. The contact box, as a core component of switchgear, directly impacts the reliability and safety of the switchgear. When installing branch busbars, the distance between the two outermost branch busbars must reach 360mm. Therefore, if the distance is less than 360mm, the branch busbars on both sides must be tilted to ensure a safe distance.

[0003] The existing equipment has the following drawbacks: traditional equipment requires the inlay tilt angle to be designed separately according to the installation distance of the branch bus, which increases the manufacturing cost of the equipment. In addition, the existing equipment lacks an effective support mechanism when installing branch buses, which makes the installation process cumbersome and makes it difficult to guarantee the stability and reliability after installation.

[0004] Therefore, this application proposes a switchgear contact box to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a contact box for switchgear, so as to solve the problem that the tilt angle of the insert needs to be designed separately according to the installation distance of the branch bus, which increases the manufacturing cost of the equipment.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-9 This utility model provides a technical solution: a contact box for a switchgear, including a contact box 1, a box top 12 disposed at the upper end of the contact box 1, a rectangular box 11 disposed between the contact box 1 and the box top 12, and further comprising:

[0029] Insert 13 is provided on the top of the box 12 for mounting the stationary contact 2 and the branch busbar 3;

[0030] Adjustment device 4, which is installed on the top of box 12 and connected to insert 13, is used to adjust the installation angle of branch bus 3;

[0031] The support member 15 is adjustablely disposed in the rectangular box 11 and is used to support the branch busbar 3.

[0032] It should be noted that during operation, when the distance between the branch busbars 3 is greater than 360mm, the inserts 13 of the three sets of contact boxes 1 are arranged in parallel. Then, the branch busbars 3 are inserted from the rectangular box 11 into the interior of the contact box 1. The branch busbars 3 and the stationary contact 2 are then fixed inside the inserts 13. The support member 15 can support the branch busbars 3 when they are inserted into the rectangular box 11. When the distance between the branch busbars 3 is less than 360mm, the branch busbars 3 are fixed to the inserts 13. Then, the distance between the branch busbars 3 is adjusted by the adjusting device 4, causing the branch busbars 3 on both sides to expand outwards. Finally, the distance between the branch busbars 3 is measured. When the distance between branch busbars 3 exceeds 360mm, the adjusting device 4 is fixed, thereby fixing the installation position of the branch busbars 3. Through the design of the insert 13 and the adjusting device 4, the position and angle of the branch busbars 3 can be easily installed and adjusted to meet the practical needs of different working conditions and reduce manufacturing costs. The adjusting device 4 can ensure that the branch busbars 3 maintain a stable posture after installation, avoiding loosening and displacement problems caused by installation errors or long-term use. The support 15 adopts an elastic design, which can flexibly support the branch busbars 3 during use, making it convenient to adjust the installation angle of the branch busbars 3 later, thus improving the reliability and stability of the switchgear.

[0033] In one embodiment, the adjusting device 4 includes a rotating shaft 41 rotatably passing through the top of the box 12, a turntable 42 fixed to the upper end of the rotating shaft 41, and a fixing bolt 43 threadedly connected to the turntable 42. The top of the box 12 is provided with a fixing groove 1202 for fixing the fixing bolt 43, and the turntable 42 is provided with a threaded hole 4201 for installing the fixing bolt 43. The lower end of the rotating shaft 41 is fixed to the insert 13.

[0034] This design is for reference. Figure 4-5 ,as well as Figure 8 By fixing bolt 43, it is rotated out of fixing groove 1202, and then the restriction of turntable 42 on rotating shaft 41 is released. Then, turntable 42 is rotated to drive rotating shaft 41 to drive insert 13 to rotate along rotating shaft 41. By controlling the rotation angle of turntable 42, the installation angle of branch bus 3 can be finely adjusted to meet different installation requirements.

[0035] In one embodiment, the insert 13 is fixedly connected to the stationary contact 2 and the branch busbar 3 at the position corresponding to the rotating shaft 41 by a positioning bolt 6, and the insert 13 is fixedly connected to the branch busbar 3 at a position away from the rotating shaft 41 by a retaining bolt 5. The insert 13 is provided with a positioning hole 1302 for installing the positioning bolt 6 and a retaining hole 1301 for installing the retaining bolt 5. The branch busbar 3 is provided with a first mounting hole 301 for installing the retaining bolt 5 and a second mounting hole 302 for installing the positioning bolt 6.

[0036] This design is for reference. Figure 8 ,as well as Figure 9 The positioning bolt 6 tightly connects the insert 13, the rotating shaft 41, and the stationary contact 2 together through the positioning hole 1302, forming a stable structural system. The retaining bolt 5 further fixes the insert 13 to the branch busbar 3 through the retaining hole 1301, ensuring the stability of the internal structure of the entire contact box 1. The opening of the positioning hole 1302 and the retaining hole 1301 provides the positioning bolt 6 and the retaining bolt 5 with precise installation positions, thereby ensuring the relative positional accuracy between the stationary contact 2, the branch busbar 3, and the adjusting device 4.

[0037] In one embodiment, the support member 15 includes an elastic member 151 fixed on a rectangular box 11 and a support plate 152 fixed on the upper end of the elastic member 151 for supporting the branch bus 3. The rectangular box 11 has an installation groove 1102 for installing the elastic member 151 and a window 1101 for placing the branch bus 3.

[0038] This design is for reference. Figure 6 ,as well as Figure 8 The elastic element 151 is made of a damped spring or an elastic pad. The introduction of the elastic element 151 enables the support plate 152 to have a certain degree of adjustability, which can ensure the support of the branch bus 3 and facilitate the subsequent adjustment of the branch bus 3.

[0039] In one embodiment, a rotating groove 1201 for mounting a turntable 42 is provided on the top 12 of the box.

[0040] This design is for reference. Figure 7 The turntable 42 is mounted on the top of the box 12 via the rotating groove 1201. This design ensures that the turntable 42 remains stable after installation and is not easy to loosen or fall off, thereby enhancing the stability of the entire structure.

[0041] In one embodiment, the contact box 1 is provided with heat dissipation fins 14 at a position below the rectangular box 11.

[0042] This design is for reference. Figure 1-4 ,as well as Figure 7 The heat dissipation fins 14 increase the contact area between the contact box 1 and the surrounding air, which helps to accelerate the dissipation of heat, reduce the internal temperature of the contact box 1, and thus protect the internal electrical components from high temperature.

[0043] Furthermore, if the embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relation to the specification. The significance or implied number of the indicated technical features is not specified. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
