Homemade small power transformer
Homemade communication 220V single-phase power transformer, can be divided into design calculations and detailed winding of two stages.
1. design calculation power transformer winding power transformer, first of all, according to the required voltage, current, etc., calculations to determine the production parameters of the transformer. (1) Determine the power of the power transformer.
(2) Determine the size of the core cross-sectional area S based on the transformer's power P. (3) Calculate the voltage per volt.
(3) Calculate the number of turns per volt.
(4) Calculate the number of turns in each winding of the primary and secondary.
(5) Select the enameled wire according to the current of each winding. In the above example, the primary winding L1 of the current I1
2. Detailed production of power transformer design calculations are completed, you can do the following steps to produce.
(1) with insulating cardboard to make a wire package frame, the following side of the board on both sides of the primary and secondary windings, respectively, open the lead hole.
(2) Winding the primary winding. Weld the enameled wire to the lead wire, and the exposed parts such as the welding point are wrapped with insulating paper, and the lead wire is threaded out of the lead hole in the side panel of the wire wrapping frame. After the primary winding is wound, the end of the wire is also connected to the lead wire like the wire head.
(3) Wrap a layer of insulating paper around the primary winding and then wind the secondary winding. Since the enameled wire used for the secondary winding is thicker, it can be used directly as the lead wire.
(4) After all the windings are wound, the outermost layer should be wrapped with insulating paper and the voltage and current of the winding should be marked on both sides.
(5) Next insert the silicon steel sheet core.
(6) in the core on the outside of the clamping shell made of iron, power transformer will be made. Then after dipping paint, drying and other insulation treatment, this power transformer can be used.
