[0002] Reactors are common devices in power systems, used to regulate voltage and current in circuits. However, corrosion of reactor joints is a common problem during use. The main reasons are as follows:

[0003] Environmental conditions: The external environment of the reactor may contain humid, acidic, or alkaline chemicals, especially in coastal areas or industrial zones. Without proper protection, these substances can corrode and damage the reactor joints.

[0004] Material selection: The reactor joint is made of corrosion-resistant material. If the material selected is of low quality or does not meet the requirements, it will easily lead to corrosion of the reactor joint.

[0005] The existing reactors still lack corrosion resistance and are prone to corrosion damage after long-term use, which can lead to power system failure. Therefore, it is necessary to improve them. Utility Model Content

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a corrosion-resistant high-frequency reactor assembly for a hydrogen fuel cell system, comprising an iron core assembly and a coil. The coil is assembled on the iron core assembly and includes a wound reactor wire. Both ends of the reactor wire are provided with terminals. The terminals are provided with quick-connect structures, which include an outer sheath and a copper tube inner core. The outer sheath is made of rubber material and is molded and connected to the sheath of the reactor wire. The copper tube inner core is sleeved on the reactor wire core. When an external wire is connected, the outer wire core of the external wire is inserted into the copper tube inner core, and the copper tube inner core is clamped and connected to both the outer wire core and the reactor wire core to achieve electrical connection between the reactor wire and the external wire.

[0008] In a further technical solution, the core assembly includes an upper core plate, a lower core plate, a central iron rod, and two side iron plates. The upper core plate and the lower core plate are respectively arranged vertically.

The central iron rod is located in the middle position, and the two side iron plates are located on both sides. The central iron rod is sleeved on a winding bracket, and the reactance wire is wound on the winding bracket.

[0009] In a further technical solution, a ceramic washer is fitted on the upper and lower parts of the winding bracket.

[0010] In a further technical solution, internal threaded openings are respectively provided at the center positions of the upper core plate and the lower core plate; the outer surface of the central iron rod is formed with external threads, and the central iron rod is threaded to the internal threaded openings of the upper core plate and the lower core plate respectively.

[0011] In a further technical solution, a limiting nut is provided at the top of the central iron rod. The outer contour of the limiting nut is set in a regular hexagon, and the bottom surface of the limiting nut is matched with the upper surface of the upper core plate.

[0012] In a further technical solution, threaded holes are provided at the four corners of the upper core plate and the lower core plate; through-holes are provided on both sides of the side iron plate, and a fastening screw is inserted through each hole. The fastening screws are threaded to the corresponding threaded holes of the upper core plate and the lower core plate to achieve fastening assembly between the upper core plate, the lower core plate and the side iron plate.

[0013] In a further technical solution, limit connection parts are formed at the four corners of the lower core plate to fix the reactor assembly.

[0014] In a further technical solution, the outer surfaces of the upper core plate, lower core plate, central iron rod, and two side iron plates are respectively coated with an anti-oxidation layer, which includes pickling and passivation paste, silicon carbide coating, or silane treatment agent.

[0015] In a further technical solution, the wall thickness of the inner core of the copper tube is 0.1mm-0.5mm.

[0016] The advantages of this invention compared to the prior art after adopting the above structure are:

[0017] 1. Through the double protection structure of rubber outer sheath and copper tube inner core, the joint is effectively isolated from the corrosion of external humid and acidic / alkaline environments. Compared with traditional single metal joints, the corrosion resistance is improved by more than 60%.

[0018] 2.
