Description
Technical field
The present invention relates to a kind of transformer line bag, relate in particular to a kind of transformer line bag of avoiding coil to produce short circuit.
Background technology
Transformer is a kind of electronic building brick commonly used, is generally used for promoting or reduces voltage in the electronic circuit.The structure of transformer generally is made up of drum stand, coil and iron core three parts, and wherein drum stand and coil constitute transformer line bag.As shown in Figure 1, drum stand is by a hollow bracket tube 10, constitute with hollow bracket tube 10 vertical space bars that link to each other 20,21,22,23,24 and connecting seat 30,31 respectively, space bar 24 links to each other with connecting seat 30 with connecting seat 31 respectively with space bar 20, is forming winding slot 50,51,52 and 53 successively between space bar 20 and 21, between 21 and 22, between 22 and 23, between 23 and 24.The hollow space of hollow bracket tube 10 is in order to place iron core 2,3, and the outer surface of hollow bracket tube 10 is in order to twine copper coil; Comprise a plurality of pins 40,41,42 and 43 on the connecting seat 30 and 31, starting point and terminal point in order to the fixed copper coil, wherein, the copper cash of secondary ports is wound between space bar 20 and the space bar 22, the copper coil of primary port is wound between space bar 23 and the space bar 24, and in order to carry out the voltage transitions between primary port and the secondary ports.
As shown in Figure 2, when the secondary end copper coil is wound in drum stand, to the end of copper cash be twisted into as shown in Figure 3 twisted wire section 220 with coil winding machine earlier, twisted wire circle 260 is left at the two ends of twisted wire section 220, again twisted wire section 220 starting points 100 are fixed on the pin 40, then, copper cash is wound on the winding slot 50, to form copper coil 60.When on the winding slot 50 behind full copper coil 60, copper cash enters in the winding slot 51 and the continuation coiling by the line recess of crossing on the space bar 21, when in the winding slot 51 around to the regulation the number of turns after, stop coiling at a high speed, at last, the twisted wire section is that approach is wound to copper cash on the terminal point pin 41 with the edge of demarcation strip 21.Because the relative current ratio of primary port is bigger, selected copper cash line footpath is thicker, be not easy broken string, so when the coiling beginning, do not need twisted wire, can directly wind the line, promptly coil winding machine is fixed in the starting point of primary port copper cash earlier on the pin 42, copper cash is wound on the winding slot 53 again, when winding turns reaches the number of turns of regulation, stop coiling at a high speed, at last copper cash is wound on the terminal point pin 43.
And the twisted wire section is set at the secondary end copper coil, be little because generally be used to drive the power of the transformer of lighting a plurality of cold-cathode tubes, be generally about 10W, but the output voltage of high-pressure side is very high, is about 1000V～2000V, promptly about the overcurrent 10mA of the copper cash of high pressure port institute, and the line of high-pressure side copper cash footpath is generally about 0.03mm, be easy on the pin cause the broken string phenomenon if be wrapped in single strand of copper wire, thus the twisted wire section is set, to increase the intensity of copper cash.
Though the drum stand of above-mentioned transformer has used for many years, but facts have proved and still have some shortcomings (as shown in Figure 4): 1, because the winding slot that is provided with on the drum stand all is used for twining copper cash, and after twisted wire section and copper cash be wound into winding slot simultaneously, because the voltage difference of 205 at the terminal point of the starting point 100 of twisted wire section and copper cash is very big in the secondary ports, for example be 1000V～2000V, the current potential of the superiors' copper coil in the high-tension coil in twisted wire section 220 and the winding slot 50 differs very big, also be to approach 500V～600V, twisted wire section 220 contacts with high-tension winding in contact-making surface 200, and regular meeting produces short circuit condition because of the problem of the insulation film defect of copper line surface; 2, because the twisted wire section has certain length, the twisted wire circle 260 of twisted wire section 220 and twisted wire section 220 ends is wrapped on the drum stand around putting later in addition rising, twisted wire circle 260 joins with the upper strata copper cash of high-tension coil, twisted wire circle 260 is when coiling, may erect or cross groove (if the twisted wire circle is around crossing the line indent, just might cross groove), twisted wire circle 260 erects and will contact with the intermediate layer copper coil of high-tension winding, so also can be because of the problem of the insulation film defect of copper line surface and produce short circuit condition; Twisted wire circle 260 is crossed groove and will be contacted with the high-tension winding of winding slot 51; twisted wire circle 260 differs bigger with the current potential of the copper coil of winding slot 51; near 1000V, regular meeting produces short circuit condition because of the problem of the insulation film defect of copper line surface, and therefore transformer is damaged and can't uses.
Summary of the invention
