Abstract
The utility model discloses an auxiliary line for grounding welding of a high-voltage cable. The auxiliary line comprises three circular copper coils, wherein the diameter of the circular copper coil is slightly greater than the wire diameter of the high-voltage cable, and the three circular copper coils are closely adjacent to each other and provided with a copper wire between each two adjacent circular copper coils. The auxiliary line for grounding welding of the high-voltage cable is simple in structure and low in manufacturing cost, the circular copper coils are sleeved on a copper shielding layer when a grounding wire is required to be welded in manufacturing the high-voltage cable, thereby reducing artificial damages factors for the high-voltage cable. A grounding resistor is tested to be good in contact, and operation requirements of the cable are met.
Description
Technical field
The utility model relates to high-tension cable ground connection welding technology field, especially relates to a kind of high-tension cable ground connection welding boost line.
Background technology
Current ， transformer station line, particularly 10～35KV transformer station line medium and high voltage cable is widely used.The manufacture craft of hv cable termination requires very high, in pyrocondensation cable termination technique, need to be with high temperature instruments such as electric iron or welding guns by three-phase copper shield welding ground connection, and still, the high temperature of instrument can cause to the insulating barrier of high-tension cable the destruction of unrepairable.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide a kind of high-tension cable ground connection welding boost line, and it can, when the copper shield ground connection welding of high-tension cable, reduce the destruction to insulating barrier.
For achieving the above object, the utility model adopts following technical scheme:
A high-tension cable ground connection welding boost line, it comprises three circular copper coils, and the slightly larger in diameter of circular copper coil is in the wire diameter of high-tension cable, and three circular copper coils are mutually close between two and are provided with between any two copper cash.
Owing to adopting technical scheme as above, the utlity model has following superiority:
This high-tension cable ground connection welding boost line, it is simple in structure, novelty reasonable in design, cost of manufacture is low, at high-tension cable, be fabricated into need to weld earth connection time circular copper coil is enclosed within on copper shield, reduced the artificial destruction factor to high-tension cable, earth resistance contact is good after tested, meets cable service requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-copper cash; 2-copper coil.
Embodiment
Below by embodiment, also by reference to the accompanying drawings the technical solution of the utility model is described in further detail.
As shown in Figure 1, this high-tension cable ground connection welding boost line, it comprises three circular copper coils 2, and the slightly larger in diameter of circular copper coil is in the wire diameter of high-tension cable, and three circular copper coils are mutually close between two and are welded with between any two copper cash 1; Above-mentioned copper coil, copper cash are 2.5mm
2the copper conductor of specification.
When the three-phase copper shield welding ground connection to high-tension cable, to inside and outside three circular copper coils, polish smooth, then be enclosed within respectively on three-phase copper shield, circular copper coil and copper shield are close to, and are welded with ground connection annealed copper wire in one of them of three circular copper coils.
