Abstract
A creepage power supply transformer with free from noise, low magnetism. Setting two annular transformers iron core 1 and 2 that are of same specification magnetic field direction reverse but close to installation. Annular transformer iron core 1 and 2 respective winding to make the primary coil 3 and coil 4 of the same circle number and the secondary coils 5, 6, 7, 8 of multi-winding group and same circle number. The same name terminal of the primary coil 3 is connected with the different name terminal of the primary coil 4. The same name terminal is connected with the different name terminal of the primary coil 3. The same name terminal of the secondary coil 5 is connected with the same name terminal of the secondary coil 7. The same name terminal of secondary coil 6 is connected with the same name terminal of secondary coil 8. The utility model adopts two annular transformer iron of the same specification magnetic field direction reverse and close to installation and the winding group of the same circle numbers, uses the theory of its magnetic field, electric field vector direction reverse, same width value, counteracting each other, so that achieving the whole the power supply transformer mechanism vibration is counteracting each other to be zero. The counteracting each other of the electric field that makes the electromagnetism width reduces ten times.
Description
Technical field
The utility model relates to the power transformer technical field, and particularly a kind of noiseless is hanged down the magnetic leakage power transformer.
Background technology
The power supply transformation all can produce machinery noise and electromagnetic radiation in various degree when using near rated power, this is unallowed in a lot of demanding occasions, for example aspects such as high precision measuring instrument instrument, high-end audio equipment and some demanding military project purposes equipment.In the prior art, for the mechanical oscillation that reduce power transformer and the influence of electromagnetic radiation, can only be under aspect the selection of material and the manufacturing process worker's time, but its effect is very little, still can not effectively overcome its machinery noise and electromagnetic radiation.
Summary of the invention
The purpose of this utility model provides a kind of low magnetic leakage power transformer of noiseless that can effectively overcome machinery noise and electromagnetic radiation.
Described noiseless is hanged down the magnetic leakage power transformer, comprise ring transformer cores, it is characterized in that: the low magnetic leakage power transformer of noiseless is provided with the ring transformer cores 1 of the opposite and arranged adjacent of two same specification magnetic directions, 2, ring transformer cores 1, be wound with the primary coil 3 of the identical number of turn on 2 respectively, 4 with the identical secondary coils 5 of many group umber of turns, 6,7,8, the end of the same name of primary coil 3 is connected with the non-same polarity of primary coil 4, the end of the same name of primary coil 4 is connected with the non-same polarity of primary coil 3, the end of the same name of secondary coil 5 is connected with the end of the same name of secondary coil 7, and the end of the same name of secondary coil 6 is connected with the end of the same name of secondary coil 8.
The utility model adopts the ring transformer cores and the identical winding of the number of turn thereof of the opposite and arranged adjacent of two same specification magnetic directions, the principle of use its magnetic field, the electric field intensity direction is opposite, amplitude equates, cancelling out each other, thereby reaching that whole power transformer mechanical vibration force cancel out each other is zero, electric field is cancelled out each other, and electromagnetic radiation has reduced ten times.
The beneficial effects of the utility model are: novel structure, effectively eliminated noise, significantly reduce magnetic leakage, be applicable to high precision instrument instrument, high-end audio equipment and high-tech area.
