Special equipment for overhauling electric wires and cables

Abstract

The invention discloses special equipment for overhauling electric wires and cables. The structure of the special equipment comprises a device main body and a glue injection needle, wherein the devicemain body is provided with a main rod, a pneumatic push box, a glue injection device, a sealing rubber gasket and a humidity observation device, and the glue injection needle is provided with a glueinjection channel, a humidity detecting head and a humidity conducting device. The special equipment has the beneficial effect of being capable of injecting water absorbing sponge into the cable in the form of a pinhole, and absorbing moisture in the cable by means of the water absorbing sponge, thereby detecting humidity in the cable by means of a detector, displaying the humidity by means of a detection lamp, being convenient to check damp situation of the cable quickly, being capable of detecting the damp section easily through setting a plurality of the glue injection needles at a certaindistance, reducing loss of the cable, detecting the damp degree without cutting the cable, sealing the pinholes with glue when removing the needles, and avoiding the cable from suffering water entrance and damping again.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a special equipment for checking and repairing wires and cables. Background technique [0002] In urban power grid engineering, cables play a particularly important role and have been widely used. It is precisely because of the particularity of cables that the cables have high requirements for installation methods and maintenance methods, especially when the cables are in the process of maintenance. In the process, there will be many problems that will occur in the cable, such as the insulator is damaged and falls off, causing leakage, or the interior of the cable is damp and water enters, which affects the service life and safety of the cable. [0003] For the current special equipment for wires and cables, relative solutions have been formulated for the following problems: [0004] In the process of cable maintenance, it is necessary to check whether the interior of the cable i...

AI Technical Summary

Problems solved by technology

[0004] In the process of cable maintenance, it is necessary to check whether the interior of the cable is damp. Generally, if the damp cable is not soaked in water, it is difficult to see whether the interior is damp from the surface. At this time, the cable should be cut to judge the damp section inside the cable. , in this case, it may be necessary to cut off a large part of the cable to confirm the wet section for maintenance, and the cable material is expensive, so a lot of cables will be wasted
