Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage disconnect switches, in particular to a high-voltage disconnect switch with an insulator that is easy to replace. Background Art

[0002] High-voltage disconnectors are key devices in power systems used to disconnect or connect high-voltage lines under no-load conditions. Insulators, as an important component of high-voltage disconnectors, are primarily used to support conductors and provide electrical insulation, ensuring that current can be safely transmitted between devices. The performance of insulators directly affects the reliability of high-voltage disconnectors and the stable operation of the entire power system.

[0003] The installation and replacement of traditional insulators is a complex and time-consuming process. Usually, insulators are fixed to the base or other supporting structure of the high-voltage disconnector by bolts. However, the bolt fixing method requires personnel to carry and use tools to remove the bolts when replacing the insulators. This process is not only time-consuming, but also increases the complexity and labor intensity of the operation. In addition, the insulators are installed by bolts. During the installation process, the operator needs to accurately align the mounting holes on the insulators with the bolt holes on the base or supporting structure. When this operation is performed at high altitude, it is affected by wind, equipment vibration and visual angle limitations, which increases the difficulty of alignment. It is easy to cause installation deviations due to inaccurate alignment, affecting electrical performance. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a high-voltage disconnector with easy-to-replace insulators.

[0005] The utility model is implemented by the following technical solution: a high-voltage disconnector with an easy-to-replace insulator comprises an auxiliary base, a positioning groove is provided on the upper surface of the auxiliary base, a movable slider is slidably connected to the interior of the positioning groove, an assembly block is fixedly connected to the upper surface of the movable slider, a first positioning hole is provided in the middle of the upper surface of the assembly block, an assembly pin is plugged into the interior of the first positioning hole, a side groove is provided on the surface of the assembly pin, a telescopic spring is fixedly connected to the interior of the side groove, and a limiting buckle is fixedly connected to the surface of the telescopic spring.

[0006] Through the above technical solution, the movable slider can slide in the positioning groove body, thereby driving the insulator to move through the assembly block, which is convenient for rapid positioning of the insulator during installation and ensures accurate installation position. The limit buckle can be retracted inside the assembly pin through the telescopic spring. When subjected to pressure, the limit buckle can be retracted inside the side groove through the telescopic spring.

[0007] As a further improvement of the above solution, the assembly block is slidably connected to the upper surface of the auxiliary base via a movable slider, and the first positioning hole is adapted to the assembly pin.

[0008] As a further improvement of the above solution, an insulator group is fixedly connected to the upper surface of the assembly block.

[0009] Through the above technical solution, the insulator group is fixedly connected to the upper surface of the assembly block, which can provide a more stable support and installation position, ensuring that the insulator maintains a stable working state under various environmental conditions.

[0010] As a further improvement of the above solution, a mounting base is fixedly connected to the interior of the auxiliary base.

[0011] As a further improvement to the above solution, a second positioning hole adapted to fit the assembly pin is provided in the middle of the upper surface of the mounting base plate.

[0012] Through the above technical solution, the design of the second positioning hole enables quick positioning during the assembly process, greatly improving assembly efficiency. The design of the positioning hole and the latch also makes subsequent maintenance and disassembly work more convenient and quick.

[0013] As a further improvement of the above solution, a through hole is opened inside the second positioning hole, and the through hole is adapted to the limiting buckle.

[0014] Through the above technical solution, the limit buckle automatically extends under the action of the spring and snaps into the through hole. This design greatly simplifies the installation steps and realizes quick installation. The function of the limit buckle is to prevent the components from loosening due to vibration or other external forces after installation, thereby improving the reliability of the connection. When adjustment or disassembly is required, just press the limit buckle to easily release the limit, which is convenient and quick.

[0015] As a further improvement of the above solution, the assembly pin passes through the first positioning hole on the surface of the assembly block, and the bottom end of the assembly pin is engaged with the inside of the second positioning hole through a limiting buckle.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model realizes the flexible sliding of the assembly block through the cooperation of the movable slider and the positioning groove body, greatly simplifies the pre-installation positioning process of the insulator group, effectively prevents the position deviation during the installation of the insulator, and improves the installation accuracy and efficiency. The combined use of the assembly pin and the limit clip not only ensures the stability and reliability of the installation of the insulator group, but also realizes the rapid replacement of the insulator through the automatic pop-up and retraction of the limit clip, thereby improving the maintenance efficiency. Compared with the traditional bolt fixing method, the device eliminates the use of disassembly tools, reduces the difficulty of operation, and saves the time required for replacing the insulator.

[0025] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-5, a high-voltage disconnector with easy insulator replacement in this embodiment includes an auxiliary base 1, a positioning groove 2 is provided on the upper surface of the auxiliary base 1, a movable slider 3 is slidably connected inside the positioning groove 2, an assembly block 4 is fixedly connected to the upper surface of the movable slider 3, a first positioning hole 5 is provided in the middle of the upper surface of the assembly block 4, an assembly pin 6 is inserted into the first positioning hole 5, a side groove 7 is provided on the surface of the assembly pin 6, a telescopic spring 8 is fixedly connected to the inside of the side groove 7, and a limiting buckle 9 is fixedly connected to the surface of the telescopic spring 8. A person slides the assembly block 4 to the upper surface of the auxiliary base 1 through the movable slider 3 to pre-position and install the insulator, and then inserts the assembly pin 6 into the first positioning hole 5. The limiting buckle 9 is subjected to the pressure of the hole wall and is contracted by the telescopic spring 8 to continue to be inserted downward inside the side groove 7.

[0028] The assembly block 4 is slidably connected to the upper surface of the auxiliary base 1 through the movable slider 3 , and the first positioning hole 5 is adapted to the assembly pin 6 .

[0029] An insulator group 10 is fixedly connected to the upper surface of the assembly block 4. The main function of the insulator group 10 is to electrically isolate the conductor from the ground potential component to ensure that the current can flow along a predetermined path without leakage or short circuit.

[0030] A mounting base plate 11 is fixedly connected to the interior of the auxiliary base 1 .

[0031] A second positioning hole 12 adapted to the assembly pin 6 is opened in the middle of the upper surface of the mounting base 11. The assembly pin 6 is engaged with the through hole of the second positioning hole 12 through the limiting buckle 9 to ensure the stability and reliability of the insulator group 10 during installation.

[0032] A through hole is provided inside the second positioning hole 12, which is adapted to the limiting buckle 9. When the assembly pin 6 is inserted into the second positioning hole 12, the limiting buckle 9 is engaged. When the limiting buckle 9 moves to the surface of the through hole, due to the lack of pressure from the hole wall of the second positioning hole 12, the limiting buckle 9 will automatically extend under the action of the telescopic spring 8. After the limiting buckle 9 is inserted into the through hole, it will fit tightly to the edge of the through hole due to the pressure of the spring to prevent loosening due to vibration or external force. When disassembly or adjustment is required, just press the limiting buckle 9 to retract it into the assembly pin 6, and the limit can be easily released for disassembly.

[0033] The assembly pin 6 passes through the first positioning hole 5 on the surface of the assembly block 4 , and the bottom end of the assembly pin 6 is engaged with the inside of the second positioning hole 12 through the limiting buckle 9 .

[0034] The implementation principle of a high-voltage disconnector with easy insulator replacement in the embodiment of the present application is as follows: a person slides the assembly block 4 to the upper surface of the auxiliary base 1 through the movable slider 3, so that the first positioning hole 5 is aligned with the second positioning hole 12, and the assembly pin 6 is inserted into the first positioning hole 5 and penetrates the assembly block 4. The limiting buckle 9 is subjected to the pressure of the hole wall and continues to be inserted downward inside the side groove 7 through the contraction of the telescopic spring 8 until the assembly pin 6 is inserted into the second positioning hole 12. When the limiting buckle 9 is aligned with the through hole in the second positioning hole 12, the limiting buckle 9 has no pressure from the hole wall, and the elastic potential energy stored in the telescopic spring 8 will push the limiting buckle 9 to extend and snap into the through hole. The hole is perforated, so that the assembly block 4 is connected to the mounting base 11, and the insulator group 10 is fixed to the surface of the auxiliary base 1, completing the assembly of the insulator. When the insulator group 10 needs to be replaced, the personnel only needs to press the limit buckle 9 to overcome the elastic force of the telescopic spring 8 and retract it into the inside of the side groove 7. The personnel can then pull out the assembly pin 6 from the second positioning hole 12 and the first positioning hole 5. At this time, the assembly block 4 is no longer fixedly connected to the mounting base 11, and the personnel can use the movable slider 3 to slide the assembly block 4 and the surface insulator group 10 out of the positioning groove body 2 on the surface of the auxiliary base 1, thereby completing the disassembly of the insulator group 10.

[0035] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
