Abstract
The utility model discloses a transformer lead connection structure which comprises a pressure welding connector, wherein one end of the pressure welding connector is connected with a paper-wrapped cable, and the other end of the pressure welding connector is connected with a wiring terminal. In the manufacturing process of a transformer lead, a cold welding structure is adopted to replace a phosphor copper welding structure, and the transformer lead connection structure has the advantages of being simple in structure, convenient to operate, safe, friendly to the environment, clean in operating environment, high in work efficiency, and the like.
Description
Technical field
The utility model relates to transformer lead structure field, is specially a kind of transformer lead syndeton.
Background technology
Lead-in wire is the important component part of power transformer, is the electric path that transformer is realized electromagnetic conversion, and succinct, rational pin configuration is the basic guarantee that transformer possesses premium properties.Traditional pin configuration is that paper bag cable first carries out phosphor-copper welding with copper strips, and then copper strips is connected with sleeve pipe oil middle connecting terminal.Because phosphor-copper welding needs professional welding personnel operation, the technical merit of welding quality and welding personnel is closely related, and poor quality controls; It is clean that the metallic particles of cooling water, towel and generation etc. all affects transformer; In welding process, easily produce waste gas, contaminated environment, and easily scald operator; Before weldering, need lead-in wire, device body etc. to protect, the postwelding operation such as need to polish, operation is loaded down with trivial details, is unfavorable for raising the efficiency.
Utility model content
The purpose of this utility model is to provide a kind of transformer lead syndeton, the problem existing to solve prior art.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of transformer lead syndeton, is characterized in that: include pressure joint, pressure joint one end and transformer paper bag cable cold connect in succession, and the pressure joint other end is connected with bushing shell for transformer oil middle connecting terminal by bolt.
Described a kind of transformer lead syndeton, it is characterized in that: described pressure joint is made up of body, the plate body that is connected to body one end, the plate body of pressure joint is connected with bushing shell for transformer oil middle connecting terminal by bolt, and the body of pressure joint and transformer paper bag cable cold connect in succession.
The utility model good effect is as follows:
The utility model is easy to operate, does not need professional and technical personnel, and simple training can operate, and crimp quality is intuitively controlled; Need not heat, not need polishing, can not produce metallic particles and waste gas, clean environment firendly; Be conducive to increase work efficiency.
Brief description of the drawings
Fig. 1 is the utility model structure front view.
Fig. 2 is the utility model structure side view.
Fig. 3 is the utility model pressure joint schematic diagram.
Embodiment
As shown in Figure 1-Figure 3.A kind of transformer lead syndeton, includes pressure joint 1, and pressure joint 1 one end is connected with 2 cold welds of transformer paper bag cable, and pressure joint 1 other end is connected with bushing shell for transformer oil middle connecting terminal 3 by bolt.
Pressure joint 1 is made up of body 11, the plate body 12 that is connected to body 11 one end, and the plate body 12 of pressure joint 1 is connected by bolt and bushing shell for transformer oil middle connecting terminal 3, and the body 11 of pressure joint 1 is connected with 2 cold welds of transformer paper bag cable.
Claims (2)
1. a transformer lead syndeton, is characterized in that: include pressure joint, pressure joint one end and transformer paper bag cable cold connect in succession, and the pressure joint other end is connected with bushing shell for transformer oil middle connecting terminal by bolt.
2. a kind of transformer lead syndeton according to claim 1, it is characterized in that: described pressure joint is made up of body, the plate body that is connected to body one end, the plate body of pressure joint is connected with bushing shell for transformer oil middle connecting terminal by bolt, and the body of pressure joint and transformer paper bag cable cold connect in succession.
