Description
Technical Field
The utility model relates to a reduce device that 10KV transformer pin joint generates heat belongs to the supporting facility technical field of power equipment.
Background
The existing transformer wire outlet terminal is a whole, a cylindrical part is connected with a wire outlet column on a transformer body, a planar part is connected with a busbar, the busbar is divided into three layers, one layer is clamped between two pieces of the wire outlet terminal, the other two layers are respectively arranged on two sides of the wire outlet terminal, and all the three layers are compressed by 9 screws of a flat plate part. When the bus bar is compressed by the connection mode, the wire outlet column part can not be compressed tightly, the contact resistance is increased, and the heat is easy to generate. The heating of the outlet terminal of the transformer can seriously affect the safe operation of the transformer.
Disclosure of Invention

Detailed Description
In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the following will combine the drawings in the embodiment to clearly and completely describe the technical solution in the embodiment of the present invention, and obviously, the embodiment described is a small part of the embodiment of the present invention, rather than the whole embodiment, based on the embodiment of the present invention, all other embodiments obtained by the ordinary skilled person in the art without creative work belong to the protection scope of the present invention.
A device for reducing the heating of a 10KV transformer lead connector comprises a bus clamp 1 and a flexible connection 2, wherein the bus clamp 1 is formed by casting a whole piece of copper and is in the shape of a combination of a circular part and a plane part, and the plane part consists of a short parallel arm and a long parallel arm; the flexible connection 2 is a copper strip and is connected with the short parallel arm of the bus clamp 1 for use, and the total length of the two connected flexible connection is equal to that of the long parallel arm; the round part of the bus clamp 1 is connected with the wire outlet column, and the bus bar 3 is connected with the flexible connection 2 and the long parallel arm of the bus clamp 1.
The busbar 3 and the flexible connection 2 are fastened with the long parallel arm of the busbar clamp 1 through six screws.
In practical application, the bus clamp is formed by casting the whole copper, and the copper strip is used for flexible connection. One part of the original structure is replaced by flexible connection, so that the circular part is connected with the wire outlet column and is pressed by three screws; a part of the busbar and the circular part are in flexible connection through a copper strip and are fastened by six screws; because there is the copper strips to cushion between the two, the atress can not influence each other. The flexible connection and the hard connection are arranged between the outgoing line column and the bus connector, so that the connection stability can be ensured, and the requirement of stress buffering can be met, thus the problem of contact fastening is solved, the contact resistance is reduced, the heating phenomenon of the outgoing line terminal of the transformer is reduced, and the potential safety hazard of the operation of the transformer is eliminated.
The utility model discloses in practical application, implementation effect is showing, and the 68 degrees before the binding post temperature falls to 35 degrees under the normal load, has eliminated transformer binding post's the hidden danger that generates heat effectively, has guaranteed the safety and stability operation of transformer, has improved the life of transformer simultaneously greatly. Furthermore, the utility model discloses the field usage of being convenient for, and low in manufacturing cost, the maintenance of being convenient for. Therefore, the overall implementation effect is good after transformation, the applicability is strong, and the method can be popularized and applied to more power transformer systems.
