Abstract
The utility model discloses a temporary winding for no-load loss testing of iron cores of a distribution transformer, which comprises a multi-core aviation plug, wherein a male socket of the aviation plug and a female socket of the aviation plug are connected in a staggered manner through a plurality of conducting wires for constituting a multi-turn open winding, and the number of the conducting wires is smaller than the number of the cores of the aviation plug by one. The temporary winding is simple to manufacture and convenient to use, and has the following advantages: the winding time of the temporary turn conducting wires is 1/15 of the original winding time and the working efficiency is improved; the testing time is reduced, the full inspection of all the iron cores can be realized and the unqualified iron cores can be prevented from flowing into the next process step; the frequency of damaging external insulations of the conducting wires is reduced and the service life of the conducting wires is prolonged; the frequency of bruising and injuring the hand of an operator is reduced and the personal professional harm is greatly reduced; and as the fixed number of the turns is adopted for measurement, the wrong number of the turns caused by artificial counting is avoided and the accuracy and the correctness of measurement are improved.
Description
Technical field
The utility model design transformer manufacturing and field tests specifically, are the empty interim windings of test that decreases of a kind of distribution transformer cores.
Background technology
At present, most of transformers, transformer core manufacturing firm carry out at the mode that the measurement of these performance index of no-load loss unshakable in one's determination is adopted sampling measurement or twine interim circle lead continuously on core limb.It is higher that this method is twined big, consuming time, the interim harness damage frequency of difficulty, very easily produces number of turn mistake, and operating personnel's hand is subjected in winding process and unshakable in one's determination damaging or abrading easily.
Summary of the invention
Goal of the invention: the purpose of this utility model is to address the above problem, and provides a kind of simple to operate, safe in utilization, and is not fragile, the empty interim winding of test that decreases of the distribution transformer cores that test accuracy is high.
Technical scheme: the empty interim winding of test that decreases of a kind of distribution transformer cores, comprise the multicore aviation plug, be cross-linked by multiple conducting wires between the male seat of described aviation plug and the female seat of aviation plug, form the open circuit winding of a multiturn, the radical of lead lacks one than the core number of multicore aviation plug.
Wherein, the first circle of described open circuit winding is connected lead-in wire respectively with last circle.
Wherein, twine with the electrical adhesive tape half-stack package outside of the female seat of the male seat of described aviation plug, aviation plug, lead and lead-in wire.
Wherein, described lead and lead-in wire are tetrafluoroethene multiply flexible cord.
The utility model is made simple, and is easy to use, possesses following effect:
1) saved winding time of interim circle lead greatly, the winding time only is original about about 1/15, has improved operating efficiency;
2) because the reduction of testing time can realize all full inspections unshakable in one's determination, avoid the defective next process that flows into unshakable in one's determination, cause and do over again, and increase quality cost;
3) reinforcement of minimizing of winding number of times and lead external insulation has reduced the frequency that the lead external insulation damages, the life cycle that has prolonged lead;
4) minimizing of twining number of times has reduced the frequency that operating personnel's hand abrades, damages, and has significantly reduced personal employment injuries;
5) owing to adopt fixedly the number of turn to measure, avoid the number of turn mistake of artificial counting generation, improved measurement accuracy.
Description of drawings
Figure is a structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in the figure, the empty damage of distribution transformer cores of the present utility model tested the aviation plug that comprises one 11 core with interim winding, ten leads 3 (radical that is lead 3 lacks one than the core number of multicore aviation plug) and two lead-in wires 4, lead 3 and lead-in wire 4 all adopt tetrafluoroethene multiply flexible cord.Be cross-linked by ten leads 3 between the male seat 1 of aviation plug and the female seat 2 of aviation plug, form the open circuit winding of one ten circle, the first circle of open circuit winding is connected a lead-in wire 4 respectively with last circle.In order to make interim winding more durable, twine with the electrical adhesive tape half-stack package at female seat 2, the lead 3 of the male seat 1 of aviation plug, aviation plug and 4 the outside of going between.
Using method of the present utility model: earlier with three groups of empty interim windings of test that decrease of distribution transformer cores of the present utility model, according to same around to respectively around to three stem stems of iron core, the number of turns of coiling is decided according to the low voltage winding in transformers design number of turn, be generally the 2-3 circle for distribution transformer cores, the promptly interim number of turn is 20 circles or 30 circles; Then three groups of interim windings are interconnected, if designed transformer low voltage winding is Y-connection, the tail end of 3 groups of interim windings is continuous, and head end is drawn stand-by; Connect if designed transformer low voltage winding is a dihedral, 3 groups of interim windings are joined end to end successively, a remaining end is drawn stand-by; Next giving interim winding energising, is example to twine 3 circles, and applied voltage designs 30 times of circle voltage for low-voltage coil; Read the no-load loss and the no-load current of this iron core at last by the loss test instrument.
Behind the EOT, cut off the electricity supply, remove interim winding, carry out the test of next iron core.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
