The ring transformer is a large type of electronic transformer. It has been widely used in electronic equipment with high home appliances and other technical requirements. Its main purpose is as a power transformer and isolation transformer.
Method method of ring transformer winding
1. Remove the old winding with scissors to cut the insulating paper and expose the secondary winding of the transformer. The trail of the secondary winding line is usually thicker. In actual maintenanceMany, so it can be dismantled one by one to count the number of turns.2. The iron heart that is insulated by the insulation treatment of the ring -shaped iron heart is usually made of high -quality high -guide magnetic rate silicon steel rolls.When the primary coil is burned, the insulating layer of the ring -shaped iron heart with the insulating paint will be damaged to varying degrees, and the paint should be performed before the re -wound.3. In order to facilitate manual operations, the stroke must make a dedicated winding line edge.4. Winding coils Wrap the primary winding first, take a high -quality high -intensity lacquer cable with the same diameter of the original thread, dual lines and wrap on the "work" shape line shuttles, and the number of circles meets the requirements.Stick the dual -line head with double -sided adhesion on the outer circular circumference of the ring -shaped iron heart, so that the shuttle shuttle is worn around the inner hole of the ring -shaped iron heart.After all winding is winding, put the ring transformer into the thermostat box for a while to dry the inside paint.Then use a thicker insulation paper on the outermost layer, and the ring transformer is made.
Benefits of ring transformers
The ring transformer magnetic flux is better than ordinary, low in electricity, and very small communication sounds.At the same time, it has a significant improvement than ordinary transformer power, the voltage is stable, and the communication noise itself can be reduced a lot.It has a good smooth and degradation effect on the voltage of the primary input.In general, it is better than ordinary transformers.
Circle transformer principle
The principle of the transformer is the principle of the transformer. When a sine AC voltage U1 is added to both ends of the primary coil, there is a cross -transformer current i1 in the wire and generates the transformer magnetic generals.The secondary coil forms a closed magnetic circuit.In the secondary coil, it is induced to induced the interaction potential U2. At the same time, the ф1 will also sense a self -sensing potential E1 on the primary coil. The direction of the E1 is similar to the opposite of the additional voltage U1, which limits the size of i1.In order to maintain the existence of magnetic flux 1, a certain amount of electric energy consumption is required, and the transformer itself has a certain loss. Although there is no load in the secondary stage at this time, there is still a certain current in the primary coil. We call this current as "empty load current current"" ".
Circular transformer power calculation
By designing a power transformer for 50Hz quartz lamps, its primary voltage U1 = 220V, secondary voltage U2 = 11.8V, secondary current i2 = 16.7A, voltage adjustment rate ΔU ≤7%, to explain the calculation method and stepsEssence1) Calculate transformer secondary power p2p2 = i2U2 = 16.7 × 11.8 = 197VA (5) 2) Calculating transformer input power P1 (Set the transformer efficiency η = 0.95) and input current i1
Circle transformer price
