Abstract
The invention belongs to the technical field of transformer structures, and particularly relates to a transformer lead connection structure. The transformer lead connection structure comprises an insulating layer and copper rods. The transformer lead connection structure is characterized in that the copper rods include the copper rod A and the copper rod B, the copper rod A and the copper rod B are connected in a conical shape, and a self-insulating layer composed of a formed insulating threaded column, a formed insulating threaded sleeve and a formed insulating sleeve is arranged around the copper rod A and the copper rod B. The transformer lead connection structure is simple in structure and convenient to use; the copper A and the copper B are connected in the conical shape instead of a traditional compression joint mode between copper rods and bolts, so that the effective connection area of the copper rods is enlarged, and conductivity is improved; besides, manufacturing cost is low, and therefore popularization and application are facilitated.
Description
(1) technical field
The present invention relates to a kind of transformer lead syndeton, belong to transformer device structure technical field.
(2) background technology
Present stage, the connected mode of the power transformer lead-in wire of 110kV and above adopts copper rod and bolt crimping more, but its connection area is little and connect weak effect, conductivity is also bad, outside needs to shield simultaneously and adds bag insulating barrier, lengthens working hours, and increases labour intensity.
(3) summary of the invention
The present invention, in order to make up the defect of prior art, provides a kind of simple in structure, can increase the effective connection area of copper rod and the transformer lead syndeton of conductivity is provided.
The present invention is achieved through the following technical solutions:
A kind of transformer lead syndeton, comprises insulating barrier and copper rod, it is characterized in that: described copper rod comprises copper rod A and copper rod B, and copper rod A and copper rod B taper connection, copper rod A and copper rod B are provided with self insulating barrier around.
Wherein:
Described copper rod A and copper rod B taper connection, substitute traditional copper rod and bolt crimping mode, increased effective connection area of copper rod, improves electric conductivity.
Profiled insulation threaded post of the present invention, profiled insulation thread bush and profiled insulation cover composition self insulating barrier, no longer need lead-in wire to wrap up, and reduced the operating time, improved operating efficiency.
The present invention is mainly used in the power transformer of 110kV and above.
The invention has the beneficial effects as follows: simple in structure, easy to use; Copper rod A and copper rod B taper connection, substitute traditional copper rod and bolt crimping mode, increased effective connection area of copper rod, improves electric conductivity; Cost is low, easy to utilize.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Accompanying drawing 1 is transformer lead syndeton schematic diagram of the present invention;
Accompanying drawing 2 is conventional wire syndeton schematic diagram.
In figure: 1, copper rod A; 2, copper rod B; 3, profiled insulation threaded post; 4, profiled insulation thread bush; 5, profiled insulation cover; 6, crimped paper insulating barrier; 7, copper rod C; 8, bolt; 9, insulating barrier.
Embodiment
Accompanying drawing is specific embodiments of the invention.
Transformer lead syndeton of the present invention as shown in Figure 1, comprise crimped paper insulating barrier 6, copper rod A1 and copper rod B2, copper rod A1 and copper rod B2 taper connection, copper rod A1 and copper rod B2 are around provided with self insulating barrier of profiled insulation threaded post 3, profiled insulation thread bush 4 and profiled insulation cover 5 compositions.
Conventional wire syndeton as shown in Figure 2, comprise copper rod C7, bolt 8 and insulating barrier 9, copper rod A1 of the present invention and copper rod B2 taper connection, substitute traditional copper rod and bolt 8 crimping modes, increased effective connection area of copper rod, improve electric conductivity, wherein profiled insulation threaded post 3, profiled insulation thread bush 4 and profiled insulation cover 5 compositions self insulating barrier, no longer need lead-in wire to wrap up, reduced the operating time, improved operating efficiency.
