Description
Technical field
The utility model relates to a kind of drum stand of pressure reduction transformer, is meant a kind of drum stand with the pressure reduction transformer that improves copper cash generation short circuit especially.
Background technology
Generally speaking transformer includes drum stand (Bobbin) and iron core (Core), and by being wound with two copper cash on the drum stand, and I sections core is inserted in the drum stand, and E sections core is located at drum stand one side, to form flux path with copper cash, in order to carrying out the voltage transitions between low pressure port and the high pressure port, thereby reach the purpose of voltage transitions.
Yet traditional transformer very easily produces situation of short circuit because of current potential differs great problem because the voltage difference between the terminal point of the starting point of the copper cash at high pressure port and copper cash is quite big.Secondly, also, make copper cash be in contact with one another, and then produce situation of short circuit that therefore transformer is damaged can't use easily because of copper cash mutual scratch of its insulation paint film in winding process comes off.
Therefore, for improving above-mentioned problem, as shown in Figures 1 and 2, drum stand 1 for known traditional pressure reduction transformer, in order to twine the first copper cash A and the second copper cash B, drum stand 1 discloses a hollow bracket pipe 11, one first connecting seat 12 and one second connecting seat 13, first connecting seat, 12 sides are provided with the first pin 14a and the second pin 14b, 13 of second connecting seats are provided with the 3rd pin 14c and the 4th pin 14d, the bottom surface of first connecting seat 12 then is provided with into first of X font to be gone into wire casing 121 and second and goes into wire casing 122, and each aslope slopes inwardly gradually.
The starting point A 1 of the first copper cash A is wrapped in the first pin 14a, and go into wire casing 121 by first, be wound in again on the hollow bracket pipe 11, the terminal point A 2 of the last first copper cash A is wrapped on the second pin 14b, and 2 of the starting point B 1 of the second copper cash B and terminal point B are wrapped on the 3rd pin 14c and the 4th pin 14d.Wherein the first copper cash A's plays the corner vicinity (as Fig. 1) that is positioned at hollow bracket pipe 11 around an A 3, to solve the short circuit problem that traditional transformer causes because of voltage difference is excessive, and by first design of going into wire casing 121, the first copper cash A of introducing will can not contacted with the copper cash line segment on being wrapped in hollow bracket pipe 11, lacquer is come off and situation of short circuit to improve the coiling friction.
Yet, rising around point of the first above-mentioned copper cash still too near the coiling section of first copper cash, so the suffering that short circuit is arranged because of the excessive problem of voltage difference is still arranged, especially the line of first copper cash directly is the line footpath less than second copper cash, easier during coiling have friction that lacquer is come off, thereby short circuit makes first copper cash in the line segment fracture that rises around a place.Further, the situation of fracture is arranged easily at the line segment of the first connecting seat corner, first copper cash promptly, transformer is damaged and can't use.
