Description

Technical Field

[0001] This utility model belongs to the field of transformer technology, and in particular relates to a magnetic saturation transformer with voltage stabilization performance. Background Technology

[0002] Magnetic saturation transformers are made using the nonlinear characteristics of the magnetization curve of an iron core. Their core cross-section differs from that of ordinary transformers, and their core structure design also differs. The primary coil has a large core cross-sectional area and is an unsaturated coil, while the secondary coil has a small core cross-sectional area and is a saturated coil. When the transformer is working, as the power supply voltage increases, the magnetic flux within the iron core also increases. When the magnetic flux within the secondary iron core reaches the saturation point, further increases in power supply voltage will only allow the increased magnetic flux to leak into the air, while the magnetic flux within the secondary iron core essentially no longer increases. Therefore, the output voltage generated by the secondary coil remains essentially constant, thus achieving voltage stabilization.

[0003] Existing magnetic saturation transformers have poor overall integrity, making them inconvenient to install, use, and adjust their characteristics. Therefore, new designs are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a magnetically saturated transformer with voltage stabilization performance, strong overall integrity, and adjustable characteristics.

A primary coil, a secondary first coil, a secondary second coil, a secondary third coil, and a secondary fourth coil are installed on the core assembly, and an external capacitor is also included. The primary coil has terminals 1 and 2, which constitute the input terminal. The secondary first coil has terminals 3 and 4, the secondary second coil has terminals 5 and 6, the secondary third coil has terminals 7 and 8, and the secondary fourth coil has terminals 9 and 10. Terminals 3, 6, and 7 are connected together, and terminals 8 and 9 are connected together. The capacitor is connected between terminals 5 and 10, and the output terminal is between terminals 4 and 8.

[0006] Preferably, the core assembly is composed of a first "mountain" shaped core and a second "mountain" shaped core, and the whole is in the shape of a "sun". There is an air gap between the joint of the first "mountain" shaped core and the second "mountain" shaped core, and a shock-absorbing air gap plate is provided in the air gap.

[0008] Preferably, the front frame, the core assembly, and the rear frame are fixedly connected. Assembly holes are provided at the four corners of both the front and rear frames, and connection holes are provided at the four corners of the core assembly. The front frame, the core assembly, and the rear frame are fixedly connected by assembly bolts located at the four corners.

[0010] The advantages and positive effects of this utility model are: This invention provides a magnetic saturation transformer with voltage stabilization performance.

[0016] In this embodiment, the core assembly 2 is composed of a first E-shaped core 2-1 and a second E-shaped core 2-2, and is in a "日" shape as a whole. An air gap is provided between the butt joint portions of the first E-shaped core 2-1 and the second E-shaped core 2-2, and a shock-absorbing air gap sheet is arranged in the air gap. Each of the first E-shaped core 2-1 and the second E-shaped core 2-2 is formed by stacking silicon steel sheets, and the entire core assembly 2 is impregnated with paint.

[0017] In this embodiment, the front frame 1, the core assembly 2 and the rear frame 14 are fixedly connected.
