Description

New energy high-frequency energy storage transformer

Technical Field

The utility model relates to a transformer, in particular to a transformer in a power switch of a new energy automobile.

Background

A Transformer (Transformer) is a device for changing an ac voltage using the principle of electromagnetic induction, and the main components are a primary coil, a secondary coil, and an iron core (magnetic core).

The electricity consumption frequency for our daily life production is 50 Hz, and we call this alternating current as low frequency alternating current. If the transformer is operated at such a frequency, we turn this transformer into a low frequency transformer, also known as a power frequency transformer. The iron core of the transformer is formed by stacking mutually insulated silicon steel sheets, the primary and secondary coils are wound by enameled wires, and the primary and secondary voltages are in direct proportion to the turns of the primary and secondary coils. In addition to this, some transformers operate at tens or even thousands of hertz, which become high frequency transformers. High frequency transformers generally do not use an iron core, but rather a magnetic core. The high-frequency transformer is a power transformer and is mainly used as a high-frequency switching power transformer in a high-frequency switching power supply. The transformer used in the switching power supply is also called an energy storage transformer, and is also called a pulse transformer.

Eight locating holes are formed in the connecting plate, and eight copper bars are matched with the eight locating holes in a one-to-one mode. Each copper bar is bent upwards to protrude out of the magnetic core, and an insulating pad is arranged on the magnetic core below the copper bar for safety although a gap exists between the copper bar and the magnetic core.

The bottom of each transformer unit is provided with a bottom limiting structure, the bottom limiting structure is concave downwards, and the magnetic core is matched in the bottom limiting structure. The magnetic core is formed by splicing a pair of E-shaped magnetic cores, so that the pair of magnetic cores spliced together are required to be fixed, and the bottom limiting structure plays a role in fixing the magnetic cores.
