Abstract
The utility model relates to an assembly structure for a coil connector bar of a dry-type transformer. The assembly structure comprises a coil starting bar, a first insulator, a second insulator, a metal clamp, a coil tail bar and a transition stud, wherein the first insulator is fixedly arranged on the coil starting bar; the second insulator is fixedly arranged on the metal clamp through a fastener; the first insulator, the coil tail bar and the second insulator are fixedly arranged on a same axis through the transition stud; an insulating pad is arranged between the coil starting bar and the first insulator; and the fastener is a locking bolt. According to the assembly structure for the coil connector bar of the dry-type transformer provided by the utility model, the transition stud is additionally arranged between the first insulator and the second insulator and the first insulator and the second insulator are fixedly connected on the same axis, so that the space for mounting a coil is reduced and the fixing of the coil starting bar and the coil tail bar is ensured.
Description
Technical field
The utility model relates to a kind of winding wiring row's assembly structure, relates in particular to a kind of winding wiring row's for dry-type transformer assembly structure.
Background technology
Dry-type transformer is to rely on cross-ventilation to cool off, and is that a kind of iron core and winding are not immersed in the transformer in the iknsulating liquid, in general dry type localized lighting, electronic circuit, the isallobaric device of plant equipment.For the larger dry-type transformer of some capacity, because the line bank of every phase coil directly is drawn out to the terminal block end, go out line position and the bonding strength when unsettled for what guarantee line bank, all the equipped insulator of design is fastened on winding wiring row on the metal clip of transformer, equipped mode commonly used is that insulator is arranged up and down, and coil is started to arrange with ending row is connected and fixed respectively (as shown in Figure 1).
But find that in real work there are some problems in such assembling mode, when winding wiring row's emersion space is restricted, the distance that is line bank emersion upper clamping piece is restricted, the mode of arranging up and down insulator just can not realize, can not be applicable to being mounted with of jumbo dry-type transformer line bank.
The utility model content
The utility model purpose is to provide a kind of requisite space little in order to overcome the deficiencies in the prior art, the assembly structure of the dry-type transformer coil line bank that applicability is strong.
For achieving the above object, the technical solution adopted in the utility model is: a kind of assembly structure of dry-type transformer coil line bank, comprise coil start row, the first insulator, the second insulator, metal clip, coil ending row and transition double-screw bolt, described coil is fixed with the first insulator on starting and arranging, and described the second insulator is fixed on the metal clip by securing member; Described the first insulator, coil ending row and the second insulator are fixed on the same axis by the transition double-screw bolt.
Preferably, described coil is started and also is provided with insulation cushion between row and the first insulator.
Preferably, described securing member is lock-screw.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
The assembly structure of a kind of dry-type transformer coil line bank of the utility model scheme, by between the first insulator and the second insulator, having set up the transition double-screw bolt, so that the first insulator and the second insulator are fixedly connected on the same axis, so just reduce the space that coil is installed, and guaranteed coil the fixing of row and coil ending row of starting.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of assembly structure of the dry-type transformer coil line bank of prior art;
Accompanying drawing 2 is the structural representation of the assembly structure of dry-type transformer coil line bank of the present utility model;
Wherein: 1, the coil row that starts; 2, the first insulator; 3, the second insulator; 4, metal clip; 5, coil ending row; 6, transition double-screw bolt; 7, insulation cushion; 8, lock-screw.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
The assembly structure of described in the utility model a kind of dry-type transformer coil line bank as shown in Figure 2, comprise coil start row the 1, first insulator 2, the second insulator 3, metal clip 4, coil ending row 5 and transition double-screw bolt 6, described coil is started to arrange on 1 and is fixed with the first insulator 2, and described the second insulator 3 is fixed on the metal clip 4 by securing member; Described the first insulator 2, coil ending row the 5 and second insulator 3 are fixed on the same axis by transition double-screw bolt 6; Described coil is started and also is provided with insulation cushion 7 between row's the 1 and first insulator 2; Described securing member is lock-screw 8.
The assembly structure of dry-type transformer coil line bank of the present utility model, by between the first insulator 2 and the second insulator 3, setting up transition double-screw bolt 6, so that the first insulator 2 and the second insulator 3 are fixedly connected on the same axis, so just reduce the space that coil is installed, guaranteed coil the fixing of row 1 and coil ending row 5 of starting.
Below only be concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
