Description

Technical Field

[0001] The utility model relates to the technical field of grading ring protection plates, in particular to an installation structure of a grading ring protection plate. Background Technique

[0002] Due to the stray capacitance between the high-voltage arrester and the ground, the voltage distribution along the arrester is uneven. In this way, the place with high voltage is prone to damage. Therefore, a grading ring is added to balance the stray capacitance to the ground, make the voltage distribution uniform, and prevent local breakdown and damage. The higher the voltage level, the greater the stray capacitance to the ground.

[0003] The installation structure of the grading ring protection plate in the prior art is a whole-wrapped protection. Such a large outer shell will cause the volume of the entire grading ring to become larger. Therefore, the whole will appear relatively large and heavy and will cause excessive load-bearing pressure below. Therefore, those skilled in the art provide an installation structure of a grading ring protection plate to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to provide an installation structure of a grading ring protection plate to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an installation structure of a grading ring protection plate, including an installation rod, the top of the installation rod is fixedly connected with an arrester, a plurality of grading ring bodies are vertically and fixedly sleeved on the outer wall of the installation rod, two clamping rings are clamped on the outer wall of the installation rod, and L-shaped connecting frames are fixedly connected to the mutually remote sides of the two clamping rings. A plurality of protective shells are fixedly connected to the mutually opposite sides of the two L-shaped connecting frames. The inner walls of the tops of the plurality of protective shells are respectively closely attached to the outer walls of the plurality of grading ring bodies.

[0006] As a further scheme of the utility model: two cross holes are symmetrically opened on the inner side of one of the clamping rings, and two cross rods are symmetrically and fixedly connected to the inner side of the other clamping ring. The two cross rods are respectively inserted and clamped in the two cross holes.

[0007] As a further scheme of the utility model: connecting plates are fixedly connected to the mutually opposite sides of the two L-shaped connecting frames, and a plurality of wire clamping tubes are communicated with the bottom of the connecting plates.

[0008] As a further scheme of the utility model: a conductive rod is fixedly connected to the bottom of the L-shaped connecting frame, and the conductive rod is located below the plurality of grading ring bodies.

[0009] As a further scheme of the utility model: insulating plates are fixedly connected to the mutually opposite sides of the two L-shaped connecting frames, and the outer wall of the connecting plate is fixedly connected to the inner side of the insulating plate.

[0010] As a further solution of the present utility model: the protective shell is supported by engineering plastics, and the protective shell is L-shaped.

[0011] As a further solution of the present utility model: the opposite sides of the multiple snap rings and the protective shell are all in contact with each other, and the multiple snap rings and the protective shell are all arc-shaped.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] The two snap rings are installed on the outer wall of the installation rod by being snapped together after docking. Multiple cross rods and cross holes are respectively arranged on the two snap rings. When the two cross rods are snapped into the two cross holes, the docking of the two snap rings can be completed. At this time, the two snap rings and the multiple protective shells will fit together to form a complete whole. The conductive rod located below can be wound with a grounding wire, and then the grounding wire can be connected to the ground.

[0014] The present utility model is simple to use. The multiple snap rings and the grading ring body are installed by tower-shaped splicing, which can reduce the volume of the entire protective shell. And the L-shaped protective shell is more ventilated. After the conductive rod located below is connected to the grounding wire, it can be grounded to guide the current. The protective shell made of engineering plastics is lighter in weight and corrosion-resistant, which can directly reduce the overall weight of the multiple protective shells, thereby reducing the pressure below.
