Description

Technical Field

[0002] GIS high-voltage cable terminal is a device that connects SF6 gas-insulated fully enclosed combined electrical and cross-linked polyethylene cables. It mainly connects and improves the electric field at the cable end. It is generally composed of a conical base atom made of epoxy resin and an end contact.

[0036] Specifically, the base assembly 100 includes a reinforcement ring 106 , which is fixed to the surface of the positioning shell 103 , and the bottom of the reinforcement ring 106 is fixedly connected to the bottom plate 101 .

[0037] The fixed connection between the reinforcement ring 106 and the base plate 101 plays a role in reinforcing the positioning shell 103 .

[0039] By driving the servo motor 105a, the transmission rod 105b drives the first gear 105c to rotate. When the first gear 105c rotates, it will engage the second gear 105d to rotate. When the second gear 105d rotates, it will drive the threaded rod 105e to rotate. At this time, the second gear 105d will assist in rotating in the inner cavity of the connecting shell 104 through the bearing.

[0040] Specifically, the driving member 105 also includes a threaded sleeve 105f, an extension plate 105g, a lifting plate 105h, a sliding plate 105i, a sliding rod 105j and a limit plate 105k.

[0048] Example 3

[0049] Reference Figure 3 and Figure 5 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0050] Specifically, the limiting member 203 includes a fixing plate 203a, a screw 203b, a torsion block 203c and a retaining ring 203d. The fixing plate 203a is fixed on both sides of the top of the support plate 201, the screw 203b is arranged in the inner cavity of the fixing plate 203a, and one side is fixedly connected to the torsion block 203c, and the retaining ring 203d is fixed on one side of the screw 203b.

[0051] The twisting block 203c is twisted to drive the screw rod 203b to rotate in the inner cavity of the fixing plate 203a. When the screw rod 203b rotates, the clamping ring 203d is driven to move, thereby contacting the cable terminal to limit it.

[0052] Specifically, the limiting member 203 further includes a limiting rod 203e and a positioning ring 203f. The limiting rod 203e is fixed to one side of the clamping ring 203d, and the other side penetrates to the outside of the fixing plate 203a and is fixedly connected to the positioning ring 203f.

[0053] When the clamping ring 203d moves, the limiting rod 203e is driven to move, thereby limiting the movement of the clamping ring 203d.

[0054] Specifically, the limiting member 203 further includes a protective strip 203g, which is fixed to one side of the clamping ring 203d, and the clamping ring 203d is made of rubber.

[0055] The material of the protective strip 203g is rubber, which provides a protective limit to the surface of the cable terminal.

[0056] When in use, first place the cable terminal body 202 in the support plate 201, then move the device to the installation position, then twist the torsion block 203c to drive the screw 203b to rotate in the inner cavity of the fixing plate 203a, and when the screw 203b rotates, it will drive the clamping ring 203d to move, and the protective strip 203g on the clamping ring 203d will be in protective contact with the cable terminal body 202, while improving the stability of the cable terminal body 202 during lifting, and then drive the servo motor 105a to make the transmission rod 105b drive the first gear 105c to rotate, and when the first gear 105c rotates, it will mesh with the second gear 105d rotates, and when the second gear 105d rotates, it will drive the threaded rod 105e to rotate. At this time, the second gear 105d will assist in rotating in the inner cavity of the connecting shell 104 through the bearing. When the threaded rod 105e rotates, the threaded sleeve 105f will move. When the threaded sleeve 105f moves, it will drive the extension plate 105g to move. When the extension plate 105g moves, it will drive the lifting plate 105h and the sliding plate 105i to move. At this time, the sliding plate 105i assists in lifting and lowering on the surface of the sliding rod 105j, so that the cable terminal body 202 is lifted by the lifting plate 105h, so as to facilitate the installation work.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
