Abstract
The utility model discloses a rectification transformer in the field of transformers. The rectification transformer comprises an upper iron core and a lower iron core, wherein three core columns are arranged between the upper iron core and the lower iron core; each core column is sleeved in a primary side winding and a secondary side winding which is arranged between the primary side winding and the core column; each core column is sleeved in four secondary side windings in two pairs; the two secondary side windings are stacked from top to bottom; each pair comprises an internal winding and an external winding concentrically arranged; the internal winding of one pair is the winding D while the external winding is the winding Y; the internal winding of the other pair is the winding Y while the external winding is the winding D; wire leads are extracted out from the upper end and the lower end of the internal winding and the external winding; and the winding D presents a delta connection while the winding Y presents a star connection. The insulation distance between the primary side winding and the secondary side winding is reasonable, which improves the space factor between the core column and the windings. The utility model has simple wiring, convenient production, short production period and low cost.
Description
Technical field
The utility model relates to a kind of rectifier transformer winding construction, belongs to the transformer technology field.
Background technology
Existing rectifier transformer, comprise upper core and lower core, be arranged with three stem stems between upper core and the lower core in parallel, each stem stem is set with first side winding outward, first side winding is provided with some secondary side winding outward, described secondary side winding is the round pie of diameter unanimity, secondary side winding superposes in pairs and is sleeved on outside the first side winding, two windings of every centering are all D winding or Y winding, two windings of its adjacent pairs correspond to Y winding or D winding, and each secondary side winding is extracted lead-in wire respectively out, and are unified at last by copper bar triangularity or Y-connection, wherein D winding triangularity connects, and the Y winding becomes Y-connection.Its weak point is: this rectifier transformer manufacturing process complexity, and life cycle of the product is longer, has wasted the plenty of time; Primary side is near stem stem, and insulation distance between the two is less, causes discharge easily; Its lead-out wire has much lifts one's head, and the pad between the copper bar is many.
The utility model content
The purpose of this utility model provides a kind of rectifier transformer, solves existing rectifier transformer insulation distance and is difficult to handle, and the problem of secondary side winding wiring difficulty can shorten the manufacturing cycle, reduces technology difficulty.
The utility model is achieved through the following technical solutions: a kind of rectifier transformer, comprise upper core and lower core, be arranged with three stem stems between upper core and the lower core in parallel, each stem stem is set with first side winding and secondary side winding outward, described secondary side winding is arranged between first side winding and the stem stem, the described secondary side winding of the outer suit of each stem stem is provided with four in pairs, two pairs of secondary side winding are stacked up and down, every centering comprises the interior winding and the outer winding of concentric setting, wherein the interior winding of a centering is the D winding, and outer winding is the Y winding; Interior winding in another group is the Y winding, and outer winding is the D winding, described in winding and outer winding extract lead-in wire out from two ends up and down, D winding triangularity connection wherein, the Y winding becomes Y-connection.
The utility model is arranged on secondary side winding between first side winding and the stem stem, and the symmetrical up and down quadripartion structure of one-tenth, change original first side winding and leaned against near the structure of stem stem, make the insulation distance of first side winding and secondary side winding reasonable, effectively improved simultaneously the activity coefficient between stem stem and the winding, compared with prior art, the utlity model has following beneficial effect: the lead-in wire of secondary side winding is few, lead-in wire is by the above-below direction outlet, the manufacture process easy operating, easy-to-connect, insulation distance is reasonable, can shorten the manufacturing cycle, reduce technology difficulty.
Description of drawings
Fig. 1 is the utility model structural representation
Fig. 2 is that the A-A of Fig. 1 is to view.
Among the figure, 1 upper core, 2 folders, 3 stem stems, 4,8 interior windings, 5,7 outer windings, 6 first side winding, 9 lower cores, 10 insulating boards.
Embodiment
Below, in conjunction with the accompanying drawings structure of the present utility model is made concrete elaboration:
As illustrated in fig. 1 and 2, be a kind of rectifier transformer, its structure mainly comprises upper core 1 and lower core 9, be arranged with three stem stems 3 between upper core 1 and the lower core 9 in parallel, upper core 1, be connected to a fixed through folder 2 and screw rod between the lower core 9, isolated between folder 2 and corresponding upper core 1 and the lower core 9 through insulation cardboard 10, each stem stem 3 outer first side winding 6 and secondary side winding of being set with, secondary side winding is arranged between first side winding 6 and the stem stem 3, the described secondary side winding of each stem stem 3 outer suit is provided with four in pairs, two pairs of secondary side winding are stacked up and down, every centering comprises the interior winding 4 of concentric setting, 8 and outer winding 5,7, wherein the interior winding 4 of a centering is the D winding, and outer winding 5 is the Y winding; Interior winding 8 in another group be the Y winding, and outer winding 7 be the D winding, described in winding 4,8 and outer winding 5,7 go between from two ends extraction up and down, D winding triangularity connection wherein, the Y winding becomes Y-connection.
The secondary side winding of this device turns to up and down the quadripartion structure of symmetry, up and down and about adopt and intersect connection, saved considerable manufacturing cost.
The utility model is not limited to the foregoing description, replaces with equivalence as the obvious distortion of said structure all to fall in the protection range of the present utility model.
