[0002] The pole-mounted switch in the power system is an important distribution equipment, which undertakes the important task of opening and closing the circuit in the outdoor environment. With the growth of power demand and the progress of technology, the design of the pole-mounted switch not only needs to meet the basic electrical performance requirements, but also needs to have good mechanical stability and environmental adaptability. The traditional pole-mounted switch is usually composed of a switch mechanism box, an arc extinguishing chamber, a current transformer and other main components, and the connection mode between these components is directly related to the reliability and maintenance cost of the equipment. Early pole-mounted switches often use simple mechanical fixing methods such as welding or bolt connection. Although this method has a simple structure, it is easy to loosen due to vibration during long-term use, which affects the safe operation of the equipment.

[0003] In recent years, with the development of material science and mechanical engineering, the locking structure of the pole-mounted switch has been improved, and various new materials and technical means have been introduced, such as adding damping devices and optimizing the design of connecting pieces, to improve the stability and service life of the equipment. However, the existing locking structure still has some shortcomings, and the center of gravity cannot be locked at the middle point of the two supports, so that one of the supports bears a large force, and long-term use can easily produce vibration, so we propose a locking structure of a pole-mounted switch.

[0010] Optionally, the bottom plate is connected with the bottom plate by the second bolt, and a countersunk hole is formed on the bottom plate.

[0011] Compared with the prior art, the utility model has the advantages that:

[0012] 1. By setting the scale line and the strip-shaped mounting port on the base plate, the flexible adjustment of the equipment installation position is realized, so that the operator can quickly and accurately adjust the center of gravity of the equipment to the middle point of the two support frames according to the actual situation. Such design not only simplifies the installation process, but also ensures the balanced distribution of the equipment, thereby reducing the additional load borne by the single-side support frame.

[0020] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] like Figs. 1 to 4 As shown in the figure, this utility model provides a locking structure for a column-mounted switch.

[0022] The system includes a pole-mounted switch mechanism box 3. The upper part of the pole-mounted switch mechanism box 3 is provided with an arc-extinguishing chamber 1. A current transformer 2 is connected to one side of the arc-extinguishing chamber 1. The lower part of the pole-mounted switch mechanism box 3 is provided with a first support frame 4 and a second support frame 5. The first support frame 4 and the second support frame 5 are respectively installed on both sides of the utility pole. The first support frame 4 and the second support frame 5 are connected by several screws 6. Several nuts are connected to the screws 6. A pad 7 is provided on the upper part of the first support frame 4 and the second support frame 5. A center plate 15 is fixedly connected to the upper center of the pad 7. The left and right sides of the center plate 15 are provided with scale lines 14 located on the pad 7, which are used to observe whether the position of the pad 7 is located at the midpoint between the first support frame 4 and the second support frame 5.

[0023] The pad 7 has a strip-shaped mounting opening 13. A rubber shock absorber 16 is fixedly connected to the upper part of the pad 7. A base plate 8 is connected to the upper part of the pad 7. The upper part of the base plate 8 is connected to the lower part of the column-mounted switch mechanism box 3.

[0024] The pad 7 is connected to the second support frame 5 and the first support frame 4 by long bolts 9 respectively. The second support frame 5 and the first support frame 4 are respectively provided with first mounting holes 10.

[0025] The bottom part of the base plate 8 is provided with a positioning groove 11, which is engaged with the center plate 15.

[0026] The bottom of the base plate 8 has a mounting groove, and a silicone buffer block 12 is glued to the bottom of the mounting groove.

[0027] The lower part of the pad 7 is welded with reinforcing ribs 19, and the pad 7 is connected to the base plate 8 by the first bolt 18.

[0028] The base plate 8 is connected to the base plate 8 by the second bolt 17, and the base plate 8 has countersunk screw holes.

[0029] Working Principle: In use, the column-mounted switch locking structure of this utility model first achieves precise position adjustment through the strip mounting opening 13 and scale line 14 on the pad 7. The operator can adjust the position of the pad 7 using the strip mounting opening 13 according to actual needs, and by observing the scale line 14, ensure that the center plate 15 on it is precisely located in the middle of the first support frame 4 and the second support frame 5, ensuring that the center of gravity of the equipment is in the optimal position. At this time, by observing the scale line 14, it can be confirmed that the equipment is correctly aligned, thereby avoiding excessive stress on one side of the support frame and enhancing the stability of the overall structure. Next, the pad 7 is fixed to the first support frame 4 and the second support frame 5 using long bolts 9, and tightened using the first mounting hole 10 to ensure a firm connection.

[0030] The rubber damping block 16 fixed to the upper part of the pad 7 plays a crucial role in vibration damping. When the pole-mounted switch is subjected to external vibration or impact, the rubber damping block 16 can absorb and disperse these forces, preventing them from being transmitted to the pole-mounted switch mechanism box 3, thereby protecting the internal electrical components from damage and ensuring the normal operation of the pole-mounted switch. In addition, the presence of the rubber damping block 16 also reduces the risk of fatigue damage to the equipment caused by long-term vibration, extending the service life of the equipment.

[0031] The positioning groove 11 at the bottom of the base plate 8 engages with the center plate 15, ensuring precise alignment between the base plate 8 and the pad 7. The design of the positioning groove 11 allows the base plate 8 to quickly find the correct position during installation and connect to the pad 7 via the first bolt 18. Simultaneously, the silicone buffer block 12 bonded within the mounting groove at the bottom of the base plate 8 further enhances the shock absorption effect of the equipment, ensuring good working condition under various environmental conditions.

[0032] In summary, through reasonable structural design and selection of appropriate materials, this utility model not only improves the stability of pole-mounted switches during installation and use, but also enhances their resistance to environmental interference, providing a solid foundation for the reliable operation of power systems.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
