       The working principle and production process of high voltage packet

First, the working principle of high pressure pack:

High voltage pack, proper name is line output transformer, also known as the pack or line change; When there is an AC current in the primary coil, an AC flux is generated in the iron core (or magnetic core), which induces a voltage (or current) in the secondary coil. A high voltage package transformer consists of an iron core (or magnetic core) and a coil. The coil has more than or equal to two windings, of which the winding connected to the power supply is called the primary coil and the others are called the secondary coil. In a generator, electromotive force can be induced in the coil whether the coil is moving through a magnetic field or the magnetic field is moving through a stationary coil. In both cases, the value of the magnetic flux is the same, but the magnetic flux in the chain intersecting the coil changes. That's how mutual induction works. A transformer is a device that uses electromagnetic mutual inductance to change voltage, current and impedance.

Second,Production process of high pressure pack:

The secondary winding and primary winding are wound successively outside the magnetic core, and then the wound high pressure packet is vacuum-pumped and placed in the mold for encapsulation, poured with glue, and finally put into the oven for solidification and forming. Pay attention to the selection of high pressure pack to choose vacuum perfusion, such as non-vacuum perfusion, the bubble in the high pressure pack is not good, the internal is easy to damage, greatly reducing the service life of the high pressure pack.
