The technology of winding the output transformer is a rather delicate work, since any inaccuracies can lead to nonlinear distortions and voltage differences on the primary windings. In this regard, it is necessary to first get acquainted with the theoretical part and calculate the necessary parameters, and then proceed to direct manufacturing.
Necessary
- - electric or hand drill;
- - machine with a coils stacker;
- - magnetic circuit;
- - the frame of the output transformer.
Instructions
Step 1
Prepare a bobbin winder in advance. In a primitive form, it can be represented by an ordinary electric or hand drill, which is clamped in a vice. In this case, it is necessary to make a bent threaded rod, which is fixed in wooden blocks. An ideal case would be the presence of a special winding machine with a stacker of turns and a counter of their number, since such a device will provide the most dense ordinary layer-by-layer winding.
Step 2
Select the type of frame of the output transformer to be wound on. You can purchase an industrial one, but it does not always fit and is quite expensive. You can make it yourself. To do this, use fiberglass or getinax material with a thickness of 1.5-2mm. The most primitive option would be to purchase a polypropylene tube with a diameter of 20 mm and a length of 5-6 cm in a plumbing store. Appropriate small indentations are made on it for winding the wire.
Step 3
Purchase a magnetic circuit for the output transformer. Judging by the quality of work, the type of this material is not significant, however, it will be most convenient to wind the O-shaped tape split core-type magnetic circuit. Purchase the required footage with a margin.
Step 4
Attach the output transformer section frame to the rewinder. If you used a drill, then wrap the electrical tape around the drill so that the frame is held tight and even. Secure the core of the magnetic core and start winding. Make sure that the wires are not piled on top of each other and run smoothly and in layers.
Step 5
Wind the primary and secondary windings in this way, and then connect them in series. Fill the output transformer with hot paraffin wax to simulate vacuum processes. You can also use epoxy.
