Technical Field

[0001] The utility model relates to an insulating base for a lightning arrester, in particular to an insulating base for a lightning arrester of a low-voltage switch cabinet. Background Art

[0002] Low-voltage switchgear is a key device used in power systems to control, protect, and distribute low-voltage electricity. It is widely used in power plants, substations, industrial and mining enterprises, high-rise buildings, and other locations. It typically consists of a cabinet, switchgear, busbars, cables, relays, and instruments, and features a compact structure, comprehensive functionality, and ease of operation.

[0003] The arrester insulation base in low-voltage switchgear is a crucial component for ensuring the proper operation of the arrester. Its primary function is to support the arrester and maintain a certain degree of insulation between the arrester and the ground, thereby preventing incorrect wiring caused by direct grounding of the arrester. The insulation base is typically made of high-alumina porcelain or monolithic porcelain and is bolted to the base steel frame.

[0004] However, the insulating base of the lightning arrester is generally set in a triangular shape. It is fixed to the basic steel frame by bolts, and its three corners need to be installed one by one. This installation method is time-consuming and has low work efficiency.

[0005] At the same time, the existing insulating base cannot be adjusted if it is fixedly connected to the basic steel frame by bolts. However, if the position needs to be adjusted, there are certain limitations. Utility Model Content

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figure 1-Figure 7 As an embodiment of the present invention, the lightning arrester insulating base of the low-voltage switch cabinet includes a basic steel frame 1 and a slider 2 slidably arranged inside the basic steel frame 1, and a quick installation mechanism is provided on the top of the slider 2:

[0030] The quick installation mechanism includes a stud 9, the surface of which is rotatably connected to a tripod 7, and when the stud 9 moves downward, the tripod 7 is synchronously moved downward;

[0031] A horizontal adjustment mechanism is also provided on the inner side of the basic steel frame 1 . The horizontal adjustment mechanism includes a screw rod 11 . The screw rod 11 is used to adjust the horizontal positions of the tripod 7 and the stud 9 .

[0032] In this embodiment, when it is necessary to install an insulating base on the basic steel frame 1, a synchronous and rapid installation can be achieved through the provided quick installation mechanism. The stud 9 is rotated. Since the stud 9 and the tripod 7 are rotatably connected and can and can only rotate relative to each other, when the stud 9 moves downward, it will also drive the tripod 7, thereby making the tripod 7 move downward. When the tripod 7 moves downward, it will be quickly installed through other structures in the quick installation mechanism, and the screw rod 11 can also be used to adjust the horizontal position of the lightning arrester on the basic steel frame 1.

[0033] As a further solution of the present invention, the basic steel frame 1 is provided as a group, and a group of the basic steel frames 1 is provided on the low-voltage switch cabinet.

[0034] In this embodiment, the basic steel frame 1 is fixedly installed on the low-voltage switchgear, and the distance between the inner sides of a group of basic steel frames 1 is fixed.

[0035] As a further solution of the present invention, a threaded groove is provided inside the slider 2 , and the screw rod 11 is threadedly connected to the slider 2 .

[0036] In this embodiment, the inner position of the slider 2 on the base steel frame 1 can be adjusted by rotating the screw rod 11 .

[0037] As a further solution of the present invention, a slide groove 101 is opened inside the shell of the basic steel frame 1, and the quick installation mechanism also includes a connecting gasket 3. A limiting block 301 is set at the bottom of the connecting gasket 3. The limiting block 301 can slide inside the slide groove 101, and the bottom of the limiting block 301 is connected to the slider 2.

[0038] In this embodiment, the connection gasket 3 can slide on the basic steel frame 1. When the screw rod 11 adjusts the position of the slider 2, the slider 2 can synchronously drive the connection gasket 3 to move through the limit block 301.

[0039] As a further solution of the present invention, the quick installation mechanism also includes a lower base 4, an upper base 5 and an adjusting rod 6, the upper base 5 is arranged above the slider 2, the lower base 4 is located between the slider 2 and the upper base 5, the lower base 4 is slidingly connected to the slider 2, the other end of the connecting gasket 3 is arranged between the lower base 4 and the upper base 5, the upper surface of the adjusting rod 6 is provided with a spiral groove, and is rotatably connected to the upper base 5, the lower surface of the adjusting rod 6 is provided with a threaded protrusion, and is threadedly connected to the lower base 4, a hemispherical groove 701 is provided on the inner wall of the tripod 7, and the threaded grooves on the upper surfaces of the tripod 7 and the adjusting rod 6 are connected by a ball 10.

[0040] In this embodiment, combined with the first embodiment, when the tripod 7 moves downward, the spiral groove on the upper surface of the adjusting rod 6 will be squeezed by the ball 10, so that the adjusting rod 6 can rotate, and the adjusting rod 6 and the upper base 5 are rotatably connected and can and can only rotate relative to each other, so the adjusting rod 6 cannot move axially downward, so that the bottom of the adjusting rod 6 is threadedly connected to the lower base 4. Since the lower base 4 cannot rotate, when the adjusting rod 6 is rotated, the lower base 4 will slowly push the connecting gasket 3 and the bottom of the upper base 5 to clamp, thereby synchronously completing the connection between the upper base 5 and the basic steel frame 1, and quickly installing the insulating base structure on the basic steel frame 1.

[0041] As a further solution of the present invention, the upper base 5 and the stud 9 are threadedly connected, and a convex ring is provided on the surface of the adjusting rod 6 , and the convex ring is located on the upper surface of the upper base 5 .

[0042] In this embodiment, when the stud 9 rotates, it moves downward in the upper base 5. A convex ring is provided on the surface of the adjusting rod 6 to prevent the adjusting rod 6 from moving downward, so that the adjusting rod 6 can only rotate.

[0043] As a further solution of the present invention, an insulating seat 8 is provided on the top of the stud 9, and a lightning arrester is threadedly connected to the inner wall of the insulating seat 8.

[0044] In this embodiment, when the stud 9 is initially rotated, an insulating seat 8 is pre-connected to the top of the stud 9. When the stud 9 is rotated, the insulating seat 8 is actually rotated. When the position of the insulating seat 8 and the basic steel frame 1 is determined, a lightning arrester is installed on the insulating seat 8.

[0045] As a further solution of the present invention, the threaded protrusions provided on both sides of the screw rod 11 are in opposite directions.

[0046] In this embodiment, the threaded protrusions on both sides of the screw rod 11 are arranged in opposite directions so that when the screw rod 11 is adjusted, the screw rod 11 will synchronously push the slider 2 to move toward the middle or to both sides, thereby adjusting the position of the insulating base on the basic steel frame 1.

[0047] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
