GIS withstand voltage test discharge rod

Abstract

This utility model relates to the field of power tool technology and discloses a GIS withstand voltage test discharge rod. A copper column head is threaded to the top of the intermediate rod, and a hook is fixedly installed on the side of the copper column head. A strip-shaped opening is formed inside the copper column head, and a hinge shaft is inserted into the inner wall of the strip-shaped opening. A sealing rod is movably installed on the outer side of the hinge shaft. By pressing down the pressure plate, the sliding sleeve moves downward, and the clamp disengages from the end of the sealing rod. Then, an insulating pull rope is tied to the end of the sealing rod. Simultaneously, the torsion spring returns to its original deformation, controlling the other end of the sealing rod to rotate into the notch. The copper column head is then threaded onto the top of the intermediate rod, which is threaded onto the top of a telescopic rod. The telescopic rod is then opened, and by holding the insulating sleeve, the hook can be hooked onto the clamp of the GIS withstand voltage equipment. The sealing rod seals the bottom of the hook, ensuring that the entire discharge rod will not accidentally fall off the hook.

Description

Technical Field

[0001] This utility model relates to the field of power tool technology, specifically a GIS withstand voltage test discharge rod. Background Technology

[0002] Before commissioning, GIS substations require an aging withstand voltage test to verify that the insulation performance of the newly installed equipment meets operational requirements. After the aging withstand voltage test, a significant amount of residual charge remains inside the GIS substation, necessitating effective discharge to ensure that this residual charge does not injure personnel. Conventional discharge rods are simply rods with hooks. When these rods are attached to the primary side clamp of the GIS substation, accidental contact or strong winds can cause them to fall from a height, potentially injuring people or damaging the GIS substation on the ground. This compromises the safety of personnel and the substation during the discharge process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a GIS withstand voltage test discharge rod that is not easily detached, thus solving the aforementioned problems.

[0005] (II) Technical Solution

[0006] To achieve the aforementioned goal of preventing detachment, this utility model provides the following technical solution: a GIS withstand voltage test discharge rod, comprising an insulating sleeve, a telescopic rod inserted inside the insulating sleeve, a middle rod threaded to the top of the telescopic rod, a copper column head threaded to the top of the middle rod, a hook fixedly installed on the side of the copper column head, a strip-shaped opening inside the copper column head, a hinge shaft inserted through the inner wall of the strip-shaped opening, a sealing rod movably installed on the outer side of the hinge shaft, a torsion spring fitted into the pre-drilled section of the sealing rod located outside the hinge shaft, a notch corresponding to the sealing rod on the inner side of the hook, and a protrusion fixedly installed on the side of the notch.

[0007] Preferably, a conductive post is fixedly installed on the surface of the copper post head, a locking nut is threadedly connected to the threaded section of the conductive post, a collar is fitted on the outside of the conductive post, and a grounding wire is fixedly installed at the bottom of the collar.

[0008] Preferably, the copper column head has an internal mounting groove, the opening of the mounting groove is provided with a horizontal plate, a sliding sleeve is slidably installed inside the mounting groove, two symmetrically arranged clamping pieces are fixedly installed on the top of the sliding sleeve, pressure plates are fixedly installed on the sides of the clamping pieces, and a spring is fixedly installed on the bottom of the sliding sleeve.

[0009] Preferably, the sealing rod has a rope hole at its tail end, and an insulating pull rope is provided inside the rope hole.

[0010] Preferably, the horizontal plate is placed between two clamping pieces, and the inner bottom wall of the strip-shaped opening has a groove opposite to the pressing piece.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, this utility model provides a GIS withstand voltage test discharge rod, which has the following beneficial effects:

[0013] 1. This GIS withstand voltage test discharge rod works by pressing down the pressure plate, causing the sliding sleeve to move downwards, and the clamping plate to disengage from the end of the sealing rod. Then, an insulating pull rope is tied to the end of the sealing rod. At the same time, the torsion spring returns to its original deformation, thereby controlling the other end of the sealing rod to rotate into the notch. Then, the copper column head is threaded onto the top of the intermediate rod, which is threaded onto the top of the telescopic rod. Then, the telescopic rod is opened, and by holding the insulating sleeve, the hook can be hung on the clamp of the GIS withstand voltage equipment. The sealing rod will seal the bottom of the hook, ensuring that the entire discharge rod will not fall off the hook accidentally.

[0014] 2. When the sealing rod is not in use, rotate the sealing rod 90 degrees to release the pressure on the pressure plate. The spring pushes the sliding sleeve upward, and the two clamps fit perfectly into the end of the sealing rod. Then, the sealing rod is vertically hidden in the strip opening, so that the entire discharge rod is in two working states, one with a seal and the other without a seal, realizing the dual use of the entire discharge rod.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-2 A GIS withstand voltage test discharge rod includes an insulating sleeve 1, a telescopic rod 2 is inserted inside the insulating sleeve 1, the telescopic rod 2 extends and retracts like a fishing rod, this is prior art and will not be described in detail; the top of the telescopic rod 2 is threadedly connected to an intermediate rod 3, the top of the intermediate rod 3 is threadedly connected to a copper column head 4, and a hook 5 is fixedly installed on the side of the copper column head 4 for hanging on the wire.

[0024] Please see Figure 2-6 A conductive post 6 is fixedly installed on the surface of the copper post head 4. A locking nut 7 is threadedly connected to the threaded section of the conductive post 6. A collar 8 is fitted on the outside of the conductive post 6. A grounding wire 9 is fixedly installed at the bottom of the collar 8 to guide the current to the ground.

[0025] Please see Figure 2-6 The copper column head 4 has a slotted opening 10 inside. A hinge pin 11 is inserted into the inner wall of the slotted opening 10. A sealing rod 13 is movably installed on the outer side of the hinge pin 11. A rope hole is opened at the tail end of the sealing rod 13, and an insulated pull rope 20 is installed inside the rope hole. By pulling down the insulated pull rope 20, the sealing rod 13 rotates, and the hook 5 is in the open state, so it can be removed from the power cord.

[0026] Please see Figure 2-6 A torsion spring 12 is fitted onto the pre-drilled section of the sealing rod 13, located outside the hinge pin 11. A notch 14 corresponding to the sealing rod 13 is opened on the inner side of the hook 5, and a protrusion 15 is fixedly installed on the side of the notch 14. The torque of the torsion spring 12 allows one end of the sealing rod 13 to press against the protrusion 15, ensuring that the hook 5 is in a closed state and preventing the hook 5 from falling off.

[0027] Please see Figure 2-6The copper column head 4 has an internal mounting groove with a horizontal plate at its opening. A sliding sleeve 16 is slidably mounted inside the mounting groove. Two symmetrically arranged clamping pieces 17 are fixedly mounted on the top of the sliding sleeve 16. The horizontal plate is placed between the two clamping pieces 17 to prevent the sliding sleeve 16 from disengaging from the mounting groove. A pressure plate 18 is fixedly mounted on the side of the clamping piece 17, and a groove corresponding to the pressure plate 18 is formed on the inner bottom wall of the strip-shaped opening 10. A spring 19 is fixedly mounted on the bottom of the sliding sleeve 16. Using the elastic force of the spring 19, the clamping piece 17 can be locked at the end of the sealing rod 13, keeping the sealing rod 13 in a vertically concealed mode.

[0028] Working principle: When in use, by pressing down the pressure plate 18, the sliding sleeve 16 moves downward, the clamping plate 17 disengages from the end of the sealing rod 13, and then the insulating pull rope 20 is tied to the end of the sealing rod 13; at the same time, the torsion spring 12 restores its deformation, thereby controlling the other end of the sealing rod 13 to rotate into the notch 14.

[0029] Next, thread the copper column head 4 onto the top of the intermediate rod 3. The intermediate rod 3 is threaded onto the top of the telescopic rod 2. Then, open the telescopic rod 2 and hold the insulating sleeve 1 to hang the hook 5 on the clamp of the GIS withstand voltage equipment. The sealing rod 13 will seal the bottom of the hook 5 to ensure that the entire discharge rod will not fall off the hook 5 accidentally.

[0030] Conversely, by pulling down the insulated rope 20, the sealing rod 13 rotates, and the hook 5 is in the open state, so it can be removed from the power line.

[0031] When the sealing rod 13 is not in use, rotate the sealing rod 13 ninety degrees to release the pressure on the pressure plate 18. The spring 19 pushes the sliding sleeve 16 upward, and the two clamping plates 17 fit perfectly into the end of the sealing rod 13. Then, the sealing rod 13 is vertically hidden in the strip opening 10, so that the entire discharge rod is in two working states, one with a seal and the other without a seal, realizing the dual use of the entire discharge rod.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
