Embodiment Construction

[0022] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0023] As described in the background technology, when the cable terminals in the prior art are installed, due to the complexity of the construction site and the volume and weight of the assembled cable terminals, when the installation distance of the cable through the warehouse is too long, etc. In this case, it is very easy to cause the cable terminal to bend, and the cable terminal bumps into the cable compartment, thereby destroying the lead filling effect and the position of the stress cone, that is, there is a problem that the cable terminal is easy to twist and destroy the lead filling effect. In order to solve the above problems, in a typical implementation of the present application, a...

Abstract

The invention provides an anti-twist device for a cable terminal. The anti-twist device for the cable terminal comprises a hoop and at least two connecting rods, wherein each connecting rod comprises a first end and a second end, which are oppositely arranged; the first end is detachably connected with the hoop; and adjacent connection points of the connecting rods and the hoop are equal in interval. The cable terminal and a cable body are deadly locked through the hoop and the connecting rods; and the adjacent connection points of the connecting rods and the hoop are equal in interval, so that stress of the cable terminal in various orientations is in balance; twisting of the cable terminal is effectively avoided; the cable terminal is prevented from colliding with a cable tank; and damages to a lead enameling effect and a stress cone position are avoided.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an anti-twist device for a cable terminal. Background technique [0002] For the installation of 110kV and 220kV cable GIS terminals and transformer terminals, accessories are usually assembled and sealed outside the warehouse. The connection and sealing method between the cable body and the cable terminal head accessories is usually lead enamel, that is, after the lead-tin alloy is melted on site, it is tightly and evenly covered on the cable connection, and the connection and sealing are completed after the alloy is cooled. Work. Due to the characteristics of the lead-tin alloy itself, the lead-lined part cannot bear a large force, otherwise it will be easily damaged. However, due to the complexity of the construction site and the volume and weight of the cable terminal after assembly, when the installation distance of the cable through the warehouse is too long, it is very ...
