Abstract
The utility model 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 bars. The transformer lead connection structure is characterized in that the copper bars comprise the copper bar A and the copper bar B, the copper bar A and the copper bar B are in taper connection, and a self-insulated layer composed of a forming insulated thread column, a forming insulated thread sleeve and a forming insulated sleeve is arranged around the copper bar A and the copper bar B. The transformer lead connection structure is simple in structure and convenient to use. The copper bar A and the copper bar B are in taper connection, so that a traditional pressure welding mode of the copper bars and bolts is replaced, the effective connection area of the copper bars is increased, and the conductivity is improved. In addition, the transformer lead connection structure is low in manufacturing cost and convenient to apply and popularize.
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, yet 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 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, copper rod A and copper rod B taper connection, and 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.
The insulating barrier of described copper rod outer end parcel is crimped paper insulating barrier.
Described profiled insulation threaded post is threaded with profiled insulation thread bush.
Profiled insulation threaded post of the present invention, profiled insulation thread bush and profiled insulation cover form self insulating barrier, no longer need lead-in wire to wrap up, and have reduced the operating time, have 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, self insulating barrier that copper rod A1 and copper rod B2 are around provided with that profiled insulation threaded post 3, profiled insulation thread bush 4 and profiled insulation cover 5 form.
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 form self insulating barrier, no longer need lead-in wire to wrap up, reduced the operating time, improved operating efficiency.
