Description

Technical Field

[0001] This utility model relates to a transformer inductor assembly component, specifically to a fixed encapsulation structure for an energy storage converter transformer inductor. Background Technology

[0002] The transformer inductor in an energy storage converter is mainly used for filtering, energy storage, and suppressing current surges. During the DC-to-AC conversion process, the inductor and capacitor work together to form a low-pass filter circuit, smoothing the output current and reducing the impact of harmonics on the power grid or load. At the same time, it stores instantaneous energy, buffers power fluctuations, and improves system stability. Its practical applications cover scenarios such as new energy grid connection, microgrids, and uninterruptible power supply systems. It needs to adapt to a wide voltage range, high-frequency switching, and harsh conditions such as high temperature / humidity. It is usually fixed with an insulating bracket or metal frame and fastened with bolts. To improve heat dissipation efficiency, it can be mounted on a heat sink or the gaps can be filled with potting compound to enhance insulation and shock resistance.

[0003] In the prior art, 201821446852.3 discloses a power transformer inductor fixed encapsulation structure. This utility model discloses a power transformer inductor fixed encapsulation structure, including an iron core shell. A winding is provided inside the iron core shell, and fixing plates are provided on both sides of the iron core shell. Five sets of leads are provided outside the winding. A first shell is engaged with the front of the iron core shell. One side of the first shell forms a rotating structure with one side of a second shell via a rotating hinge. A fixing buckle fixed on the other side of the first shell engages in a groove opened on the other side of the second shell. A lead fixing groove with a strip-shaped opening is provided on the outside of the first shell. A winding fixing groove with a rectangular groove is provided in the middle of the second shell. Shell fixing grooves are provided on both sides of the winding fixing groove on the second shell. This power transformer inductor fixed encapsulation structure is simple to use and can be attached to the outside of the power transformer inductor structure to isolate the inductor structure from the outside environment, reducing dust adhering to the inductor structure and improving the inductor's performance.

[0004] Although the existing inductor fixing structure can reduce the dust adhering to the inductor structure and improve the inductor's performance, it cannot allow airflow at the bottom of the transformer and cannot effectively dissipate heat. Utility Model Content
