Description

Technical Field

[0001] This utility model relates to the field of high voltage switchgear technology, specifically a multi-combination type high voltage switchgear. Background Technology

[0002] Multi-combination high-voltage switchgear is designed to achieve flexible control, protection, and monitoring of high-voltage circuits. Through modular design, it integrates multiple functional units to meet the application needs of different power systems and improve the safety, reliability, and efficiency of power transmission and distribution. High-voltage switchgear operates at high voltages (typically 35kV and above). Protective covers provide physical isolation, preventing personnel from accidentally touching or approaching live parts and reducing the risk of electric shock.

[0003] In existing multi-combination high-voltage switchgear, the high-voltage switchgear is mostly fixed by bolts during installation. The bolts are prone to loosening and falling off, affecting the stability of the installation and making it difficult to control the position of the bolts. In addition, the existing multi-combination high-voltage switchgear has poor external protection for the high-voltage switchgear, and accidental contact with the high-voltage switchgear has certain safety risks. The present invention is a multi-combination high-voltage switchgear that solves the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a multi-combination high-voltage switchgear, including a high-voltage switchgear body 1 and a protective cover 2. Inside the high-voltage switchgear body 1, guide rods 3 and limit springs 4 are respectively installed. One end of the limit spring 4 is equipped with an L-shaped adjusting plate 5, one end of the L-shaped adjusting plate 5 is equipped with a limit baffle 6, and the other end of the L-shaped adjusting plate 5 is equipped with a push plate 7. A horizontal plate 8 is installed at the end of the push plate 7, and a locking block 9 is installed on the side of the horizontal plate 8 near the push plate 7. An L-shaped plate 10 is installed on the outer side of the protective cover 2, and a positioning block 11 is installed on the inner wall of the L-shaped plate 10. Matching plates 12 are installed on the front and rear of the high-voltage switchgear body 1. The interior of the matching plate 12 has threaded holes with the depth direction as the vertical direction, and bolts 13 are installed inside the threaded holes.

[0025] Specifically, it facilitates the sliding of the L-shaped adjusting plate 5 along the length of the guide rod 3, and facilitates the guiding function of the limit baffle 6 and the locking block 9.

[0026] Please see Figure 2 One side of the L-shaped adjustment plate 5 has a guide hole with the left and right directions as the depth direction, and the guide rod 3 passes through the guide hole.

[0027] Specifically, the limit baffle 6 is designed to limit the position of the bolt 13, thereby improving the stability of the installation. The protective cover 2 serves as an external protection to prevent accidental contact with the high-voltage switchgear body 1, thus improving the protection effect.

[0028] Please see Figures 1 to 5 The bottom of the limit baffle 6 abuts against the end of the bolt 13. There are two protective covers 2, and the sum of the widths of the two protective covers 2 is greater than the width of the high voltage switchgear body 1.

[0029] Specifically, the positioning block 11 serves to position and install the protective cover 2, facilitating its installation.

[0030] Please see Figures 4 to 5 The front and rear of the high-voltage switchgear body 1 are provided with positioning grooves with the front and rear directions as the depth direction, and the end of the positioning block 11 is inserted into the inside of the positioning groove.

[0031] Specifically, the two protective covers 2 are fitted together on the outside of the high-voltage switchgear body 1 to provide external protection and facilitate quick assembly and disassembly of the protective covers 2.

[0032] Please see Figures 1 to 5 The inner wall of the L-shaped plate 10 abuts against the outer side of the high-voltage switchgear body 1, and the protective cover 2 is fitted onto the outside of the high-voltage switchgear body 1, and the protective cover 2 abuts against the high-voltage switchgear body 1.

[0033] Specifically, the design of the card block 9 facilitates the restriction of the position of the positioning block 11, enables the quick installation of the protective cover 2, and improves its practicality.

[0034] Please see Figures 4 to 5 The positioning block 11 has a slot on one side with the left and right direction as the depth direction, and the end of the card block 9 away from the horizontal plate 8 is inserted into the slot.

[0035] During use, when installing the high-voltage switchgear body 1, a longer external object pushes the push plate 7 and the L-shaped adjusting plate 5 to facilitate the movement of the limit baffle 6. The guide rod 3 passes through the guide hole, causing the L-shaped adjusting plate 5 to move along the length of the guide rod 3, moving the limit baffle 6 away from the threaded hole. The bolt 13 is then tightened inside the threaded hole to install the mating plate 12 and the high-voltage switchgear body 1 into the appropriate position. Afterward, the push plate 7 and the L-shaped adjusting plate 5 are released. The elastic tension of the limit spring 4 causes the L-shaped adjusting plate 5 to move the limit baffle 6 back to its original position, allowing the limit baffle 6 to abut against the end of the bolt 13. This helps to limit the position of the bolt 13, preventing it from loosening and falling off, thus improving the stability of the high-voltage switchgear body 1 during installation. The protective cover 2 provides external protection for the high-voltage switchgear body 1, acting as a physical barrier to prevent accidental contact with the high-voltage switchgear body 1. When disassembling or replacing the protective cover 2, the horizontal plate 8 and the locking block 9 move with the push plate 7. The movement causes the locking block 9 to leave the slot, and then the protective cover 2 to move the positioning block 11 away from the positioning groove, moving the protective cover 2 away from the high-voltage switchgear body 1, facilitating the disassembly of the protective cover 2. The two protective covers 2 are fitted together on the outside of the high-voltage switchgear body 1 to provide protection. Conversely, when installing the protective cover 2, the movement causes the end of the positioning block 11 to insert into the positioning groove, making the protective cover 2 abut against the high-voltage switchgear body 1. When the sides of the two protective covers 2 abut against each other, the locking block 9 aligns with the slot on the positioning block 11. When the push plate 7 is released, the elastic tension of the limit spring 4 causes the locking block 9 to reset with the push plate 7, allowing the end of the locking block 9 to insert into the slot, facilitating the restriction of the position of the positioning block 11 and the installation of the protective cover 2. While restricting the position of the bolt 13, the position of the positioning block 11 can also be restricted, which can improve the stability of the installation and restrict the position of the protective cover 2, thus improving practicality.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
