Abstract
The utility model provides a transformer iron core no-load loss measuring winding which comprises an aviation plug connector socket, an aviation plug connector plug and a multi-core flexible cable. The number of cores of the multi-core flexible cable is at least one more than the number of poles of the aviation plug connector socket, the aviation plug connector socket is connected with the aviation plug connector plug through the multi-core flexible cable, one lead end is respectively reserved at two ends of the multi-core flexible cable, and the two ends do not belong to the same core of the multi-core flexible cable and are conducted. The transformer iron core no-load loss measuring winding can be suitable for no-load loss measuring of various types of transformer iron cores with different capacities and is very convenient and rapid to install. Compared with a current temporary winding formed through a manual winding method, the transformer iron core no-load loss measuring winding saves time and effort and greatly improves testing efficiency. In addition, the number of turns of the temporary winding is constant, the number of turns cannot be misremembered, measuring data cannot have errors, and measuring accuracy is improved greatly.
Description
Technical field
The utility model relates to a kind of transformer core open circuit loss and measures winding.
Background technology
Current, China is in the stage that Resources for construction economizing type and environmentally friendly amphitypy society constantly advance, and under global energy present situation at full stretch, advocating resources conservation is the important decision of country.Transformer has been widely used in every field as an electricity consumption product, and the consumption that the loss direct relation of transformer itself power resource, if every transformer can suitably reduce the loss of himself, the national like this electric energy that can save is immeasurable.Therefore, transformer will strictly be controlled the loss value of its body in the design production run, particularly control the size of open circuit loss unshakable in one's determination, in general, every transformer core is being made completion but also just should not measure its open circuit loss numerical value in suit coil, if find that loss is higher, just can in time search the reason processing of doing over again, unnecessary formed product is by the time just processed, and causes unnecessary loss, particularly volume is unshakable in one's determination, and this step necessarily can not be lacked.The method of independent measurement open circuit loss unshakable in one's determination is to add interim winding on each core limb, and at present, the method for making that open circuit loss is measured interim winding is exactly directly one to enclose and be entwined on core limb with insulated conductor, so not only time-consuming but also the effort, and the number of turn that is wound around is easy to make mistakes, and causes the inaccurate of measurement data.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of transformer core open circuit loss applied widely, easy to use to measure winding.
The technical scheme that the utility model adopts is: comprise aviation plug connector socket, aviation plug connector plug and a multi-core flexible cable, the core number of described multi-core flexible cable is Duoed a core at least than the number of poles of aviation plug connector socket, aviation plug connector socket is connected with aviation plug connector socket by multi-core flexible cable, the multi-core flexible cable two ends reserve respectively a conducting wire end, and two conducting wire ends do not belong to same core and the conducting of multicore flexible circuit conductor.
The beneficial effects of the utility model are: the utility model goes for the transformer core open circuit loss of various types and different capabilities and measures, install very convenient rapid again, the interim winding that forms than present manual winding method not only saves time but also laborsaving, has greatly improved the efficient of test; In addition, because the number of turn of the interim winding of the utility model is changeless, can not misremember what of the number of turn, measurement data also just can not go wrong, and has greatly improved the precision of measuring.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is back panel wiring schematic diagram of the present utility model.
Fig. 3 is work schematic diagram of the present utility model.
Specific implementation method
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model comprises aviation plug connector socket 1, aviation plug connector plug 3 and a multi-core flexible cable 2, the core number of described multi-core flexible cable 2 is Duoed a core at least than the number of poles of aviation plug connector socket, aviation plug connector socket 1 is connected with aviation plug connector socket 3 by multi-core flexible cable 2, multi-core flexible cable 2 two ends reserve respectively same core and the conducting that a conducting wire end 4, two conducting wire ends 4 do not belong to multicore flexible circuit conductor 2.
The below illustrates the annexation of aviation plug connector socket 1 and aviation plug connector socket 3 take the aviation plug connector socket 1 of four utmost points as example.as shown in Figure 2, adopt by five core flexible cables 2, during connection, first the core in five core flexible cables 2 is welded on the A terminal of aviation plug connector socket 1 and starts as of the present utility model, then, with the B terminal of three cores in five core flexible cables 2 with aviation plug connector socket 1, C terminal and D terminal respectively with A ' number terminal of aviation plug connector plug 3, B ' number terminal connects with the C number of being connected terminal, the insulated conductor of then being drawn by D ' number terminal of aviation plug connector plug 3 is as tail head of the present utility model, like this, of the present utility model head and tail head is conducting, the coil that is equivalent to two circles.The length of five core flexible cables 2 is the core limb outer circumferences of capacity maximum in transformer core 5 tested according to all and definite.
As shown in Figure 3, in figure, transformer core 5 is unshakable in one's determination for the three-phase transformer volume, therefore need to have three the utility model to match and just can complete open circuit loss measurement unshakable in one's determination.First three identical the utility model of the number of turn are enclosed within respectively on three core limbs of transformer core 5, three winding directions of the present utility model must be consistent, then with stube cable 6, three tail heads of the present utility model are linked together, design circle voltage by transformer during test is inputted the three-phase alternating-current supply of corresponding size starting of three interim windings, so just can utilize experimental apparatus to measure open circuit loss value unshakable in one's determination.
