Description
Technical field
The present invention relates to the pin configuration of large capacity oil-filled transformer, be specially a kind of D type lead-in wire fixed clamping device and method.
Background technology
Along with the development of China's superhigh pressure, high-power transformer technology, transformer capacity constantly increases, and in transformer lead, electric current constantly increases, and causing constantly increases for the outside conductor cross-section that is connected use of transformer coil exit and transformer.The wire clamp of using with anchor leg as clamping, available technology adopting be fixedly clamped structure in not affecting transformer inner space, cannot meet the lead-in wire weight of continuous increase.In prior art, conductor clamping fixed structure as shown in Figure 1, is made up of wire clamp 5 and clamp 6, by the fastening installation of insulation blanket stud.While adopting this structure, when lead-in wire makes direction by laterally drawing direction bending while being longitudinal direction by wire clamp, wire need carry out a coordinated transposition, arrangements of conductors order need be three row's two row by two row's three row coordinated transpositions, bending place becomes large because of the intersection local arrangements size of wire, and arrangements of conductors is irregular; And owing to being provided with groove in wire clamp 5, reduce its intensity on the one hand, made it cannot bear the conductor structure of large weight and most amounts, also brought inconvenience to processing on the other hand; Clamp 6 structural strengths that are mated are lower, fixing and clamping weak effect.
Summary of the invention
For problems of the prior art, the invention provides a kind of fixing cord quantity large, do not change D type lead-in wire fixed clamping device and the method for wire installation direction.
The present invention is achieved through the following technical solutions:
A kind of D type lead-in wire of the present invention fixed clamping device, comprises the first wire clamp assembly, the second wire clamp assembly and support; The first wire clamp assembly is the rectangular frame of a length sides opening, and the second wire clamp assembly is linear pattern framework, and the length sides of the second wire clamp assembly and the first wire clamp assembly opening is fixed formation closed frame, and wire clamp is held in closed frame; Parallel one end that is fixed on support of width edge of the first wire clamp assembly.
Preferably, the stiff end of support is provided with for locating fixing tapped through hole.
Preferably, first length sides of wire clamp assembly and the junction of width edge are fillet setting, and the radius of fillet is not less than the radius that is held wire.
Further, the length sides of the length of the second wire clamp assembly and the first wire clamp assembly is equal in length.
Further, the first wire clamp assembly, fixes by insulation blanket stud respectively between the second wire clamp assembly and support; The first wire clamp assembly, link position place overlapping between the second wire clamp assembly and support is fixedly connected with by same insulation blanket stud.
Further again, the second wire clamp assembly, the first wire clamp assembly and support are cascading, and the opening of the first wire clamp assembly is towards the direction setting away from support stiff end.
The present invention a kind of based on more further the lead-in wire of described D type lead-in wire fixed clamping device fix to clamp method, comprise the steps, support is fixed by the tapped through hole of stiff end, then the first wire clamp assembly is fixed on support by insulation blanket stud, being arranged in the first wire clamp assembly the constant wire column position that changes gear again, finally the second wire clamp assembly and the first wire clamp assembly are fixed, realized the arrangement of wire and fix.
Compared with prior art, the present invention has following useful technique effect:
Fixed clamping device of the present invention, the closed frame forming by the cooperation of the first wire clamp assembly and the second wire clamp assembly realizes the clamping to wire, wire can directly be drawn without coordinated transposition, do not change the installation direction of wire, size transition and variation are mild, and utilize width edge to be fixedly connected with support, ensure on the one hand reservation and location to open space when wire is installed, also the rigidity of support and the intensity of integrated connection have been ensured on the other hand, can realize multilead, the drawing and clamping of large weight wire, be specially adapted to superhigh pressure, the lead-in wire of high capacity rectangular transformer clamps and is fixing.
Further, utilize the tapped through hole arranging can efficient and conveniently realize being fixedly connected with of support, thereby provide origin reference location to ensure to lead-in wire location.
Further, arrange by fillet, can make the contact site of corner's wire become face contact by point, improved fixing and clamped effect, and having reduced the deformation of original conductor structure.
Further, arrange by wire clamp assembly equal in length, when ensureing stable connection, improve the globality of closed frame, and by the same insulation blanket stud arranging in overlapping junction, realized the raising to hard-wired simplification and bulk strength.
Further, by the overlapping of wire clamp assembly and support, and the optimization of opening direction, ensure to install time easy to connect, the work of conductor clamping operation is provided and has safeguarded space.
Clamping means of the present invention, in transformer lead process, when wire is by laterally drawing bending while being longitudinal direction again, do not carry out wire transposition, thereby wire transposition number of times in minimizing transformer lead, increase the quantity of clamping wires by the winding displacement mode that still adopts two rows three to be listed as, make to operate in lead-in wire process more practical, convenient, clean and tidy and reliable; Be suitable in superhigh pressure, the large huge transformer of capacity wire-lead radical many, what weight was large is fixedly clamped.
