Description

Technical Field

[0001] The utility model relates to the field of electric porcelain insulators, in particular to a high-strength column-type electric porcelain insulator. Background Art

[0002] Porcelain insulators are an electrical insulating material made of ceramic material. Their function is to isolate high-voltage equipment and transmission lines from the ground to prevent current leakage to the ground. The main function of porcelain insulators is to isolate the current between high-voltage equipment and transmission lines and the ground. High-strength post-type porcelain insulators are one of the many types of porcelain insulators. Post-type porcelain insulators are a cylindrical insulator composed of insulating materials and metal parts. They are connected to high-voltage equipment and transmission lines through metal parts and are used to isolate and support equipment. Post insulators are usually composed of multiple units, which are interchangeable for easy maintenance.

[0003] After searching, the publication number CN209312505U is an assembled electric porcelain insulator, which specifically discloses an assembled electric porcelain insulator, including an assembly head, a pillar, a composite umbrella group, a copper foot and a copper foot bolt. The bottom of the assembly head is fixedly connected to a connecting head, the bottom of the connecting head is fixedly connected to one end of the pillar, and the middle part of the outer surface of the pillar is fixedly connected to the composite umbrella group. In the utility model, through the cooperative operation mode of providing a fixing hole and a positioning hole, and with the cooperation of a slide groove and a baffle, when the electric porcelain insulator needs to be assembled, first the bottom edge of the electric porcelain insulator is slid into the inside of the slide groove, and the electric porcelain insulator can be fixed through the obstruction of the baffle, and then the center position of the electric porcelain insulator is aligned with the positioning hole. At this time, the four corners of the electric porcelain insulator are aligned with the fixing hole, and then the electric porcelain insulator is pressed downward to position and fix the electric porcelain insulator, which effectively improves the assembly convenience of the electric porcelain insulator. The utility model is practical and effective and suitable for wide promotion.

[0004] During use, existing post-type porcelain insulators are used in external spaces for a long time. As an important component of power equipment, their waterproof performance directly affects the safe and reliable operation of high-voltage equipment. Post-type porcelain insulators are affected by natural factors such as sunlight and rain, which will cause certain losses to the post-type porcelain insulators themselves. If they lack waterproof capabilities, the loss rate of post-type porcelain insulators will be high after long-term use, and the high-voltage equipment will easily shut down. In the above-mentioned comparative case, the post-type porcelain insulators also lack waterproof capabilities. As a result, not only can the post-type porcelain insulators not operate stably, but the probability of loss and maintenance is also increased when encountering rainy weather.

[0005] Therefore, it is necessary to invent a high-strength column type electric porcelain insulator to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a high-strength column type electric porcelain insulator, which is realized by the column type electric porcelain insulation body, umbrella skirt body, waterproof protective layer, insulating umbrella cover, mounting groove and ring column clamp when used in the outer space of the column type electric porcelain insulator, so that the column type electric porcelain insulator has good waterproof ability, reduces the loss of the column type electric porcelain insulator itself due to long-term sun and rain, and thus reduces the probability of high-voltage equipment shutdown. In this way, it not only ensures the stable operation of the column type electric porcelain insulator, but also reduces the loss and maintenance probability in rainy weather, so as to solve the problem of the column type electric porcelain insulator in the prior art during use. Since post-type porcelain insulators are used in external spaces for a long time, as an important part of power equipment, their waterproof performance directly affects the safe and reliable operation of high-voltage equipment. Post-type porcelain insulators are affected by natural factors such as sunlight and rain, which will cause certain losses to the post-type porcelain insulators themselves. If they lack waterproof capabilities, the loss rate of post-type porcelain insulators will be high under long-term use, and high-voltage equipment will easily shut down. In the above-mentioned comparative case, the post-type porcelain insulators also lack waterproof capabilities. This not only makes the post-type porcelain insulators unable to operate stably, but also increases the probability of loss and maintenance when encountering rainy weather.

[0007] In order to achieve the above-mentioned object, the present utility model provides the following technical solutions: a high-strength post-type electric porcelain insulator, comprising a post-type electric porcelain insulating body, a body for auxiliary circuit operation;

[0008] The umbrella skirt body is provided on the outside of the columnar insulator body, and is used to provide creepage distance and protect the columnar insulator body. The surface of the umbrella skirt body is pasted with a waterproof protective layer. The bottom of the columnar insulator body is fixedly installed with a mounting seat, and the top of the columnar insulator body is provided with an insulating umbrella cover.

[0009] The mounting groove is arranged inside the insulating umbrella cover and is used for docking and installing the insulating umbrella cover and the column-type electrical porcelain insulating body. An embedded groove is opened inside the mounting groove, and a second damping reset rod is arranged inside the embedded groove. A ring column clamp is fixedly installed on one end of the second damping reset rod.

[0010] Preferably, the waterproof protective layer is tightly fitted to the umbrella skirt body, and the material of the waterproof protective layer is acrylic.

[0011] Preferably, a positioning bolt is passed through the top of the mounting seat, a ring sleeve is provided on the outside of the column-type electrical porcelain insulation body, a fixing frame is fixedly installed on the outside of the ring sleeve, and a stabilizing rod is movably connected to the inside of the fixing frame.

[0012] Preferably, a buffer groove is provided on the surface of the mounting seat, and a first damping reset rod is fixedly installed inside the buffer groove.

[0013] Preferably, a lower wire pressing frame is fixedly installed above the insulating umbrella cover, a fastening bolt passes through the upper part of the lower wire pressing frame, one end of the fastening bolt is movably connected to the upper wire pressing frame, and a terminal is fixedly installed above the upper wire pressing frame.

[0014] Preferably, the annular column clamp is movably connected to the mounting groove, and the second damping reset rods are distributed at equal intervals on the mounting groove.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. The utility model is provided with a column-type electric porcelain insulation body, an umbrella skirt body, a waterproof protective layer, an insulating umbrella cover, a mounting groove and a ring column clamp. When the column-type electric porcelain insulator is used, the second damping reset rod can be pressed toward both sides of the mounting groove by the ring column clamp, so that the second damping reset rod drives the ring column clamp to retract and retract, and then the insulating umbrella cover is directly sleeved on the top of the column-type electric porcelain insulation body through the mounting groove, so that the second damping reset rod will drive the ring column clamp to resist and be installed on the top of the column-type electric porcelain insulation body. Combined with the umbrella skirt body and the waterproof protective layer, when used in the external space of the column-type electric porcelain insulator, the column-type electric porcelain insulator has good waterproof ability, reducing the loss of the column-type electric porcelain insulator itself due to long-term sun and rain, thereby reducing the probability of high-voltage equipment shutdown. This not only ensures the stable operation of the column-type electric porcelain insulator, but also reduces the loss and maintenance probability in rainy weather;

[0017] 2. The utility model is provided with a column-type porcelain insulator body, a mounting seat, a positioning bolt, a ring sleeve, a fixing frame, a stabilizing rod, a buffer groove and a first damping reset rod. Since the column-type porcelain insulator is used in mid-air for a long time, when it encounters external interference and shaking, multiple groups of stabilizing rods can drive the first damping reset rod to extend and retract toward the buffer groove of the mounting seat. Such telescopic buffering can effectively reduce the amplitude of the left and right swing of the column-type porcelain insulator, allowing the column-type porcelain insulator to remain stable when operating on high-voltage equipment, reducing the impact of external factors on the column-type porcelain insulator.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The utility model provides Figure 1-5 A high-strength post-type electric porcelain insulator shown includes a post-type electric porcelain insulating body 1, which is used as a main body for auxiliary circuit operation;

[0028] The shed body 2 is provided on the outside of the columnar insulator body 1 to provide creepage distance and protect the columnar insulator body 1. The surface of the shed body 2 is adhered with a waterproof protective layer 3. The bottom of the columnar insulator body 1 is fixedly mounted with a mounting seat 4. The top of the columnar insulator body 1 is provided with an insulating umbrella cover 11.

[0029] The mounting groove 16 is provided inside the insulating umbrella cover 11 and is used for docking the insulating umbrella cover 11 with the column-type insulator body 1. The mounting groove 16 has an embedded groove 17, and a second damping reset rod 18 is provided inside the embedded groove 17. A ring column clamp 19 is fixedly mounted on one end of the second damping reset rod 18. The second damping reset rod 18 can be pressed to both sides of the mounting groove 16 by the ring column clamp 19, so that the second damping reset rod 18 drives the ring column clamp 19 to retract and retract, and then the insulating umbrella cover 11 is directly sleeved on the top of the column-type insulator body 1 through the mounting groove 16, so that the second damping reset rod 18 will drive the ring column clamp 19 to resist and be installed on the top of the column-type insulator body 1.

[0030] like Figure 1 、 Figure 2 and Figure 3As shown, the waterproof protective layer 3 fits tightly with the umbrella skirt body 2. The material of the waterproof protective layer 3 is acrylic ester. The insulating umbrella cover 11, the umbrella skirt body 2 and the waterproof protective layer 3 can make the column type electric porcelain insulator have good waterproof ability when used in the external space of the column type electric porcelain insulator. A positioning bolt 5 is passed through the top of the mounting seat 4. A ring sleeve 6 is provided on the outside of the column type electric porcelain insulating body 1. A fixing frame 7 is fixedly installed on the outside of the ring sleeve 6. A stabilizing rod 8 is movably connected to the inside of the fixing frame 7. The first damping reset rod 10 can be driven by multiple groups of stabilizing rods 8 to extend and retract toward the buffer groove 9 of the mounting seat 4. Such telescopic buffering can effectively reduce the amplitude of the left and right swing of the column type electric porcelain insulator, so that the column type electric porcelain insulator can remain stable when running on high-voltage equipment. A buffer groove 9 is provided on the surface of the mounting seat 4, and a first damping reset rod 10 is fixedly installed inside the buffer groove 9. The structure of the first damping reset rod 10 is simple and easy to operate. If a fault occurs, it is also convenient for maintenance personnel to repair and replace it in time.

[0031] like Figure 1 、 Figure 4 and Figure 5 As shown, a lower pressing frame 12 is fixedly installed above the insulating umbrella cover 11, and a fastening bolt 13 is passed through the top of the lower pressing frame 12. One end of the fastening bolt 13 is movably connected to the upper pressing frame 14, and an end 15 is fixedly installed above the upper pressing frame 14. The lower pressing frame 12, the upper pressing frame 14 and the end 15 facilitate the connection and installation of the column type insulator with the circuit of the high-voltage equipment. The ring column clamp 19 is movably connected to the mounting groove 16, and the second damping reset rod 18 is evenly spaced on the mounting groove 16. The ring column clamp 19 clamps both sides of the column type insulator body 1, so that the insulating umbrella cover 11 is not easy to fall off when used on the column type insulator body 1.

[0032] The working principle of this utility model is as follows: first, when installing the column insulator on the high-voltage equipment, the device and the high-voltage equipment are first installed through the mounting seat 4 and the positioning bolt 5, and then the second damping reset rod 18 can be pressed to both sides of the mounting groove 16 through the ring column clamp 19, so that the second damping reset rod 18 drives the ring column clamp 19 to retract and retract, and then the insulating umbrella cover 11 is directly sleeved on the top of the column insulator body 1 through the mounting groove 16, so that the second damping reset rod 18 will drive the ring column clamp 19 to resist and be installed on the top of the column insulator body 1, and then with the umbrella skirt body 2 and the waterproof protective layer 3, when used in the outer space of the column insulator, the column insulator has good waterproof ability, which reduces the damage of the column insulator caused by long-term sun and rain. The loss of the insulator itself, thereby causing the probability of high-voltage equipment shutdown, is then reduced. After the installation is completed, when the post-type porcelain insulator is disturbed and shakes due to external factors during use, multiple sets of stabilizing rods 8 can drive the first damping reset rod 10 to extend and retract toward the buffer groove 9 of the mounting seat 4. Such telescopic buffering can effectively reduce the amplitude of the left and right swing of the post-type porcelain insulator, allowing the post-type porcelain insulator to remain stable when running on the high-voltage equipment, reducing the impact of external factors on the post-type porcelain insulator. Finally, after completing the installation and use of all the post-type porcelain insulators according to the above operations, daily maintenance of the device is sufficient. The material of the waterproof protective layer 3 is: acrylic ester, and the use process of the high-strength post-type porcelain insulator is completed.
