Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Please refer to fig. 1 and fig. 2.

The embodiment provides a grading ring pressing device, which comprises two splicing units 11, wherein each splicing unit 11 comprises a fixing ring 7 with a mounting hole, and the fixing ring 7 is sleeved on a lightning-triggering electrode 8.

At least three connecting rods 3 are connected to the outer wall of the fixing ring 7 in an extending manner. The angle between any two adjacent connecting rods 3 is equal. In the present embodiment, three tie rods 3 are used, and the angle between two adjacent tie rods 3 is equal to 120 degrees, i.e. all tie rods 3 are equally spaced around the circumference of the outer wall of the fixing ring 7.

The connecting rod 3 is far away from one end of the fixing ring 7 is provided with a fixing groove 2 for fixing the grading ring 1 through a hoop.

Two splicing units 11 are about equalizing ring 1 symmetry, two splicing units 11 mutual fixed connection.

Specifically, because equalizer ring 1 is the annular shape, consequently the base semicircular in shape of fixed recess 2, two fixed recess 2 concatenations and just in time blocks equalizer ring 1. Furthermore, the two fixing grooves 2 are fixed by screws.

Further, solid fixed ring 7, connecting rod 3 and fixed recess 2 integrated into one piece for this closing device is more firm, light, does benefit to the popularization.

As an alternative, the following fixing method is adopted between the two splicing units 11: connecting holes 6 are formed in the connecting rods 3, fixing screws 5 are installed in the connecting holes 6, and the fixing bolts penetrate through the two connecting rods 3.

In order to prevent the problem of rotational slip between the pressing device and the lightning strike, the mounting hole is square.

In order to ensure that the two splicing units 11 are tightly and fixedly connected, the surfaces of the connecting rods 3 spliced with each other are smooth planes 4.

In order to enhance the firmness of the pressing device, the splicing unit 11 further comprises a reinforcing rib 12, wherein the reinforcing rib 12 is fixed on the connecting rod 3, and one end of the reinforcing rib is connected with the outer wall of the fixing ring 7.

In summary, the equalizing ring pressing device provided by the embodiment of the invention utilizes the two splicing units 11 to be spliced together, so that the equalizing ring 1 is fastened, is portable in installation, is beneficial to connection with other equipment, has strong universality and wide application range, and can be used for not only high-voltage electrical equipment but also equalizing of a space electric field.
