Description

Technical Field

[0001] The utility model relates to the technical field of insulator installation, in particular to a novel insulator installation structure. Background Art

[0002] The traditional installation method of the insulator on the high-voltage pulse capacitor is to set a threaded mounting hole on the mounting shell, and open an adapter thread at the insertion position of the tail of the insulator, so that the insulator is installed on the high-voltage pulse capacitor by screwing the thread.

[0003] However, the tail of this type of insulator is injection-molded with threads, which are easy to slip when installed with threads in the mounting holes, resulting in loose installation. When the capacitor carries high voltage current, leakage occurs at the threaded installation. If the capacitor tips over, the oil on the inner wall will also leak from the installation.

[0004] Therefore, a new type of insulator installation structure is needed, in which a flange is used to fix the insulator and the capacitor. This can solve the problem of leakage at the installation point under high voltage transmission due to the injection molded thread stripping installation being not tight enough and the problem of oil leakage at the installation point due to the tipping of the capacitor. Utility Model Content

[0005] In order to solve the above technical problems, a new type of insulator installation structure is provided, which solves the problems of leakage at the installation point under high voltage transmission and leakage at the installation point caused by the tipping of the capacitor due to the injection-molded threaded stripping installation of the traditional insulator in the prior art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: a new type of insulator installation structure, including a shell cover and an insulator body vertically penetrating the inner wall of the shell cover, an annular skirt is arranged on the outer wall of the insulator body, and the skirt is in contact with the top surface of the shell cover, and is characterized in that: it also includes an annular groove surrounding the bottom surface of the skirt, a sealing ring in contact with the top surface of the shell cover is embedded in the annular groove, and an installation mechanism for pressing the sealing ring is arranged on the outer side of the skirt;

[0007] The mounting mechanism comprises a flange sleeved on the outer wall of the skirt and a clamping plate sleeved on the outer wall of the insulator body above the flange; the flange is fixedly connected to the top surface of the shell cover, and the clamping plate is detachably connected to the top surface of the flange.

[0008] Preferably, the clamping plate includes two flange covers which are symmetrically arranged on the top surface of the flange in a semi-circular shape, the inner walls of the two flange covers are in contact with the surface of the insulator body, and the flange covers are fixed to the flange by bolts.

[0009] Preferably, a plastic cover is provided above the skirt, the plastic cover is slidably sleeved on the insulator main body rod, and the plastic cover is opened on one side facing the skirt.

[0010] Preferably, a plastic screw barrel is fixed to the top surface of the plastic cover, and the plastic screw barrel is threadedly sleeved on the main rod of the insulator.

[0011] Compared with the prior art, the advantages of the utility model are:

[0012] (1) After the insulator body is inserted into the shell cover by setting the sealing ring and the installation mechanism, the skirt is aligned with the embedded flange, so that the outer periphery of the skirt fits with the inner wall of the flange, and then the clamping plate is attached to the flange and the top surface of the skirt for installation. The skirt is squeezed by the clamping plate and the flange, so that the skirt and the sealing ring are pressed and fit on the top surface of the shell cover, thereby increasing the sealing of the sealing ring and the skirt to the shell cover installation. In this way, the leakage phenomenon at the installation under high voltage transmission caused by the injection molding thread sliding installation is solved, and the problem of oil leakage at the installation caused by the capacitor tipping over can be solved.

[0013] (2) By covering the skirt with the clamping plate and the flange, and utilizing the fit between the skirt, the flange and the clamping plate, the sealing performance of the installation of the clamping plate and the flange on the skirt can be increased.

[0014] (3) Through the arrangement of the plastic screw barrel and the plastic cover, after the insulator body is installed on the shell cover through the flange cover and the flange plate, the plastic screw barrel can be rotated forward, and then the plastic cover is driven to descend along the insulator body through the plastic screw barrel until the plastic cover contacts the top surface of the shell cover. During this process, the plastic cover is opened to completely cover the flange cover and the flange plate, so that the external dust, dirt and humid air can be isolated from the outside through the plastic cover, thereby slowing down the rusting of the locking bolts between the flange cover and the flange plate.

[0023] By setting the sealing ring 7 and the installation mechanism, after the insulator body 1 is inserted into the shell cover 2, the skirt 8 is aligned and embedded in the flange 4, so that the outer periphery of the skirt 8 fits with the inner wall of the flange 4, and then the cardboard is attached to the flange 4 and the top surface of the skirt 8 for installation. The skirt 8 is squeezed by the cardboard and the flange 4, so that the skirt 8 and the sealing ring 7 are pressed and fit on the top surface of the shell cover 2, thereby increasing the sealing of the shell cover 2 installation. At the same time, the skirt 8 is covered by the cardboard and the flange 4, and the skirt 8 is fit with the flange 4 and the cardboard, so that the sealing of the skirt 8 installation can be further increased. In this way, the leakage phenomenon at the installation under high voltage transmission caused by the injection molding thread slipping installation is not tight enough and the problem of oil leakage at the installation caused by the capacitor tipping over can be solved.

[0024] Furthermore, it is worth noting that, referring to Figures 1 to 3 As shown, the clamping plate includes two semi-circular flange covers 3 symmetrically arranged on the top surface of the flange 4, the inner walls of the two flange covers 3 are in contact with the surface of the insulator body 1, and the flange covers 3 and the flange 4 are fixed by bolts;

[0025] By setting the clamping plate, after the skirt 8 is aligned with the flange 4 and inserted, the flange cover 3 is aligned with the flange 4 and placed in contact with the top surface of the skirt 8, and the flange cover 3 is tightly locked on the flange 4 with bolts, and the skirt 8 under the flange cover 3 is locked in the flange 4.

[0026] After using it for a period of time, it was found that due to the use environment of the high-voltage pulse capacitor and the magnetism caused by electricity during use, dust and dirt were attracted and accumulated on the bolts on the flange cover 3, and the humid air caused the bolts to rust.

[0027] In view of this, in order to solve the above problems, refer to Figures 1 to 3 As shown, it is worth noting that a plastic cover 6 is arranged above the skirt 8, and the plastic cover 6 is slidably sleeved on the rod of the insulator body 1, and an opening is opened on one side of the plastic cover 6 facing the skirt 8;

In this way, the external dust, dirt and humid air can be isolated from the outside through the plastic cover 6, and then the locking corrosion between the flange cover 3 and the flange plate 4 is slowed down.
