Abstract
The invention discloses a low-voltage outlet column of a transformer. The low-voltage outlet column comprises a column body and a connecting piece which is radially arranged on the column body, wherein an axial banking pin is arranged between the column body and the connecting piece; and the column body, the connecting piece and the axial banking pin are integrated extrusion parts. The column body and the connecting piece are integrated extrusion parts, therefore, the low-voltage outlet column has various advantages that due to low resistance, no heating phenomenon is caused when the low-voltage outlet column suffers from strong current in operation, so that the safety of a product is ensured; no displacement phenomenon is caused under the influence of factors such as mounting position change, the action of mounting tractive force and the like; and the advantages of firmness in connection and lowest consumption are achieved, and the problem that the transformer is easy to have a fault is solved.
Description
[technical field]
The invention belongs to a kind of outlet column, especially belong to a kind of transformer low voltage outlet column.
[technical background]
The transformer low voltage outlet column is used for being connected of transformer coil lead-out wire and outside line, is installed in the transformer top usually, can be divided into brass outlet column and red copper outlet column by material.Chinese patent number is that 022191291 oil-immersed power transformer low pressure conducting rod total performance is a kind of transformer low voltage outlet column, and its structure comprises shaft, and vertical configuration is arranged on the brace on the shaft, and the shaft two ends have screw thread.During assembling, transformer coil lead-out wire or outside line are connected on the brace.In practical application; There is following problem in the transformer outlet column of this structure: because brace need have the installation position-limiting action concurrently; Therefore, under factor affecting such as the variation of transformer installation site, the effect of installation tractive effort, the displacement phenomenon appears in regular meeting in the time of between brace and the shaft; Be connected with the firm of outside line thereby influence the transformer lead-out wire, cause transformer to break down.
[summary of the invention]
For solving the problems of the technologies described above, the present invention aims to provide a kind of transformer low voltage outlet column, and the phenomenon of displacement can not appear producing between brace and the shaft in the outlet column of this structure, has the high advantage of province's material and reliability.
For realizing above-mentioned purpose, the present invention has adopted following technical scheme: the structure of this transformer low voltage outlet column comprises shaft, and radially is arranged on the brace on the said shaft that it is characterized in that: said shaft and said brace are monolithic extruded.
As preferably, be provided with the axial limiting nail between said shaft and the said brace.
As preferably, said banking pin and said shaft and brace are monolithic extruded.
As preferably, the outer contour of said brace is positive circular, the thickness of brace or protrude from the radial width of shaft periphery and the diameter ratio of said shaft is respectively 0.3 and 0.8.
Beneficial effect: compared with prior art, because shaft of the present invention and brace are monolithic extruded structure, make it to have increased plurality of advantages: because resistance is little, being in operation runs into heavy current through difficult generation heating phenomenon, thereby has guaranteed product safety; Change in the installation site, install under the factor affecting such as tractive effort effect, brace is with respect to the shaft phenomenon that can not be shifted; Have be connected firmly, advantage that consumptive material is economized most, solved the troublesome problem of transformer.In addition; The present invention through experimental verification repeatedly brace thickness and protrude from the radial width of shaft periphery and the relation between the said shaft diameter; The thickness of proof brace and the ratio of the radial width and the said shaft diameter that protrude from the shaft periphery are respectively 0.3 and at 0.8 o'clock; When material adopts common industrial pure copper; Can realize effectively that not only the transformer lead-out wire is connected with the firm of external connection, and not receive the transformer installation site to change, install the influence of factors such as tractive effort, can also reach the purpose that consumptive material is economized most.Adopt the banking pin structure to help reducing consumptive material, reduce production costs.
[description of drawings]
Fig. 1 is the structural representation of one embodiment of the invention.
Among the figure: shaft 1, brace 2, screw thread 3, banking pin 4, screw thread 5.
[embodiment]
Referring to Fig. 1, the transverse shape of shaft 1 is rounded, and the brace 2 with positive circular outer contour radially is positioned on the appropriate location of shaft 1.Brace 2 is monolithic extruded with shaft 1, and 1 axial compression forms to shaft through press.
During practical implementation, for increasing the bonding strength of brace 2 and shaft 1, can between shaft 1 and brace 2, set up some pieces of axial banking pins 4, the quantity of certain banking pin 4 is decided by feelings, generally on the shaft anchor ring, is uniformly distributed with three pieces for well.During extruding, banking pin 4 and shaft 1, brace 2 are for once being squeezed into integral body.
In addition; Satisfying under the preceding topic of outlet column functional requirement; The applicant is through repetition test; Draw: when the thickness of brace 2, radial width (width of brace 2 protrusion shafts 1 periphery) preferably are respectively 0.3 and 0.8 with the ratio of said shaft 1 diameter, can reach be connected firmly, purpose that consumptive material is economized most.
