Embodiment

[0040] see figure 1 , is a structural schematic diagram of the fixed terminal assembly of the present application installed on the wire.

[0041] Such as figure 1 and image 3 As shown, the application provides a device for restoring the mechanical properties of the wire insulation layer, the device comprising:

[0042] A fixed terminal assembly 100, the fixed terminal assembly 100 is arranged at the boundary of the wire 200 whose insulation layer has been stripped and extends outward for a certain distance;

[0043] A connecting part 300, the connecting part 300 is connected to the fixed terminal 103 assembly;

[0044] The load cell 400 is installed on the connection part 300 and connected in series with the connection part 300 .

[0045] In the above technical solution, when the wire core 202 whose insulation layer has been stripped is subjected to tension, a certain friction force will be generated between the combination of the two fixed terminal assemblies 100 connected...

Abstract

The application provides a device for restoring the mechanical properties of the wire insulation layer, including a fixed terminal assembly, a connecting part and a force gauge, the fixed terminal assembly is arranged on the boundary of the wire whose insulation layer has been stripped and extends outward for a period distance; the connection part is connected to the fixed terminal assembly; the force gauge is installed on the connection part. This application resists the external pulling force through the anti-slip accessories and the friction between the anti-slip teeth and the wire insulation layer, thereby restoring the mechanical properties of the wire section whose insulation layer has been stripped, with a simpler structure, more convenient operation, and a higher safety factor; The force gauge installed on the component can monitor the force of the device in real time. When the force reaches the set threshold, an alarm will be issued to provide evidence for the staff of the operation and maintenance department, which is safer and more reliable.

Description

technical field [0001] The present application relates to the technical field of peel-off electrometric grounding rings, and in particular to a device for restoring the mechanical properties of wire insulation layers. Background technique [0002] In the occasions of operation, maintenance, and infrastructure projects of distribution network lines, it is necessary to install temporary grounding wires on the line according to the requirements of the work. Since the insulated wires are insulated from the air as a whole, there is no exposed wire part, and temporary grounding wires need to be installed for power failure operations. For the grounding wire, an electric inspection grounding ring is set on the insulated wire at a distance of about 20 cm from the insulator. The inside of the device is connected to the core of the insulated wire, and a metal ring is set outside. , can carry out electrical inspection and suspend temporary grounding wire on this ring. [0003] In the p...
