Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage cables, and in particular to a filling auxiliary device and method. Background Art

[0002] Power cables are widely used in power generation (including thermal power generation, hydropower generation and other new energy power generation), power transmission and distribution (including long-distance power transmission, substation, urban power grid and rural power grid distribution) and terminal power consumption (including rail transit, new energy, construction engineering, marine engineering, communications, petroleum, chemical industry, automobile, industrial production, etc.) and other aspects of power production, transmission and application, which are closely related to the development of the national economy and people's daily life. As a result, the competition in the high-voltage cable market is becoming increasingly fierce, and the State Grid and the Southern Grid have put forward higher requirements for the process control of cables. Due to the shape and size of the segmented sector blocks, there are gaps between the sector blocks when the segmented conductors are cabled. When the conductor shield is extruded in the cross-linking process, the conductor shield is pressed by the extrusion of the conductor shield, and the wrapping tape is concave inward, resulting in obvious gap marks on the conductor shielding layer, which is uneven. In serious cases, rework is required, resulting in a waste of materials and resources. At present, there is less filling of gaps in the industry, and the filling is non-fixed. As the segmented conductor sector blocks are brought in when they are cabled, the filling will deviate or run out of the gaps during the process.

[0003] When the split conductor is extruded into a conductor shield, there are side gaps in the split conductor. Under the pressure of the conductor shield extrusion, the wrapping tape is sunken inward, resulting in obvious side gap marks and unevenness of the conductor shielding layer.
