Abstract

The invention relates to a miniature electromagnetic-type voltage transformer, which comprises an ultra-crystalline magnetic core, a primary coil, a secondary coil and a four-pin conjoined box cover, wherein the ultra-crystalline magnetic core is installed inside an insulating shell, the primary coil and the secondary coil are wound on the magnetic core, the four-pin conjoined box cover is used for leading out the primary coil and the secondary coil, and the transformer is poured and sealed through epoxy resin. The miniature electromagnetic-type voltage transformer is characterized in that a protecting box is sleeved outside the magnetic core, an environment-friendly Mylar adhesive tape is pasted on the outer surface of the protecting box, and a polyester film is jacketed inside the magnetic core. The miniature electromagnetic-type voltage transformer has the beneficial effects that the structure is simple, hardening processing is simply realized on an original basis, the cost is lowered, and the own performance of the voltage transformer is improved.

Description

technical field [0001] The invention belongs to the field of voltage transformers, and relates to a miniature electromagnetic voltage transformer, which is especially suitable for accurately transforming high-level AC voltage signals into low-level AC voltage signals, so as to be suitable for electronic devices of microprocessors. Circuits and other devices, and the present invention uses epoxy resin potting to withstand harsh natural environments without affecting its performance. Background technique [0002] The current voltage transformers are generally used in outdoor high-voltage occasions, and are rarely used in occasions where the internal space of the device is small. The voltage transformer of the present invention is small in size and light in weight, but the weakness of this miniature voltage transformer is that it is relatively poor in high voltage resistance and stability, so how to solve these two problems has always been a concern for those skilled in the art...
