Description

Technical Field

[0001] This utility model relates to the field of reactor technology, and in particular to a series reactor for low-voltage capacitors that is easy to assemble. Background Technology

[0002] A reactor, commonly known as an inductor, is a core inductive component widely used in power systems and electronic circuits. Its core function is to store and regulate energy through electromagnetic induction. Its core structure consists of four parts: an iron core, which is the main body of the magnetic circuit; an upper yoke and a lower yoke located at both ends of the iron core to close the magnetic circuit; and an AC working winding that realizes the conversion of electrical energy into magnetic energy. The AC working winding is formed by tightly wound insulated wires around the iron core. After its two ends are reliably connected to the power system circuit, it can not only realize the basic functions of limiting the short-circuit current of the circuit and preventing the fault from spreading, but also supplement the reactive power of the system, suppress harmonic interference, and ultimately ensure the stable operation of the power system.

[0003] Existing series reactors for low-voltage capacitors are inconvenient to quickly fix during winding module assembly. The fixing method during production is cumbersome and relies on manual operation, which prolongs the assembly time and limits the production capacity. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an easy-to-assemble low-voltage capacitor-specific series reactor, which facilitates the rapid fixing of winding modules, reduces adjustment time, and improves overall assembly efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easily assembled low-voltage capacitor-specific series reactor, comprising a mounting base, wherein the mounting base has four snap-fit ​​components inside, each snap-fit ​​component including a telescopic rod installed inside the mounting base, the outer wall of the telescopic rod being fitted with a spring, the telescopic end of the telescopic rod being connected to a movable block, the outer wall of the movable block being respectively connected to a slider, a plug rod, and a connecting rod, the mounting base having a groove adapted to the slider inside, and a slot adapted to the plug rod inside.

[0006] As a further technical solution of this utility model, each of the connecting rods has an insulating block connected to the end of the mounting base after passing through the end of the moving block, and an anti-slip sleeve is fitted on the outer wall of each insulating block.

[0007] As a further technical solution of this utility model, the mounting base has two sets of slots inside, and each set of slots has a mounting bracket slidably connected inside.

[0008] As a further technical solution of this utility model, each of the mounting brackets is equipped with two insulating plates, and a coil is provided between the two insulating plates.

[0009] As a further technical solution of this utility model, each of the mounting brackets has an iron core installed inside, and each of the coils has two terminals installed on its outer wall.

[0010] As a further technical solution of this utility model, two fixing plates are provided on the two mounting brackets, and two fastening bolts are provided inside the two fixing plates. Each fastening bolt passes through the two fixing plates and one of the mounting brackets in sequence and is threaded with a nut.

[0011] As a further technical solution of this utility model, the mounting base has two strip-shaped grooves inside, and each strip-shaped groove is threaded with two fixing bolts.

[0012] This invention provides an easy-to-assemble low-voltage capacitor-specific series reactor, which has the following advantages compared with the prior art:

[0013] This design presents an easily assembled low-voltage capacitor-specific series reactor. A snap-fit ​​assembly consisting of a telescopic rod, spring, and insertion rod allows the insertion rod to automatically snap into the slot using spring force, achieving rapid positioning and fixation of the winding module and mounting base. This replaces the cumbersome operation of bolt tightening, improving assembly efficiency. The cooperation between the slider and the groove precisely guides the movement trajectory of the movable block, ensuring accurate alignment of the insertion rod and slot, guaranteeing installation stability. The insulating block at the outer end of the connecting rod facilitates manual gripping and force application, while the anti-slip sleeve increases friction, making operation effortless and preventing slippage. This, in turn, improves overall assembly efficiency, ease of operation, and safety. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution for an easily assembled low-voltage capacitor-specific series reactor: It includes a mounting base 1, which serves as the basic carrier of the reactor's overall structure, providing installation space and support for components such as the snap-fit ​​assembly 2 and the iron core 9, ensuring stable assembly positions for each part. The mounting base 1 contains four snap-fit ​​assemblies 2, which are the core structure for quickly fixing the winding module to the mounting base 1. They are fastened using their own component linkages instead of bolts, simplifying assembly operations. Each snap-fit ​​assembly 2 includes a telescopic rod 201 installed inside the mounting base 1. The telescopic rod 201 limits the extension and retraction direction of the spring 202, and simultaneously... The movable block 203 provides stable support for movement and prevents it from shifting. The outer wall of the telescopic rod 201 is fitted with a spring 202, which uses its own elasticity to drive the movable block 203 to move, providing power for the insertion rod 206 to automatically engage with the slot 5, thus achieving rapid fixation. The telescopic end of the telescopic rod 201 is connected to the movable block 203. The outer wall of the movable block 203 is connected to the slider 204, the insertion rod 206, and the connecting rod 205, respectively. The movable block 203 connects the slider 204, the insertion rod 206, and the connecting rod 205, which can transmit the force of the spring 202 to each related component, coordinate the linkage of multiple components, and ensure smooth engagement.

[0021] The mounting base 1 has an internal groove 3 that matches the slider 204. The groove 3 is sized to match the slider 204, providing a sliding path for the slider 204. By limiting the movement trajectory of the slider 204, the displacement direction of the movable block 203 is indirectly constrained, ensuring that the insertion rod 206 can be accurately aligned with the slot 5, thus guaranteeing the stability and accuracy of the engagement action. The mounting base 1 also has an internal slot 5 that matches the insertion rod 206. The slot 5 is structurally compatible with the insertion rod 206 and serves as the engagement and positioning point for the insertion rod 206. Through the engagement with the insertion rod 206, the winding module is directly engaged. The mechanical fixation of the block to the mounting base 1 prevents the parts from loosening or shifting after assembly. Each connecting rod 205 has an end away from the movable block 203 that passes through the mounting base 1 and is connected to an insulating block 207. The insulating block 207 is made of insulating material, which can isolate current conduction and avoid the risk of electric shock during assembly or maintenance, ensuring operational safety. Each insulating block 207 has an anti-slip sleeve 208 on its outer wall. The anti-slip sleeve 208 increases the friction between the hand and the insulating block 207, making it more stable for the operator to hold and preventing slippage when applying force, thus improving the convenience and reliability of operation.

[0022] The mounting base 1 has two sets of slots 4 inside, which provide a sliding assembly path for the mounting bracket 6, facilitating quick alignment and insertion of the mounting bracket 6, while limiting the lateral displacement of the mounting bracket 6 to ensure its assembly accuracy with the mounting base 1. Each set of slots 4 has a mounting bracket 6 slidably connected inside, and each mounting bracket 6 has two insulating plates 7 installed on it. The insulating plates 7 are installed on both sides of the coil 8, and the insulating material blocks the current conduction between the coil 8 and the mounting bracket 6 to avoid the risk of leakage and ensure the electrical safety performance of the reactor. A coil 8 is set between the two insulating plates 7. An iron core 9 is installed inside each mounting bracket 6. The iron core 9 serves as the magnetic circuit carrier of the coil 8, enhancing the magnetic field strength generated by the coil 8, improving the reactance efficiency of the reactor, and providing structural support for the coil 8. Two terminals 13 are installed on the outer wall of each coil 8.

[0023] Two mounting brackets 6 are provided with two fixing plates 10. The two fixing plates 10 are provided with two fastening bolts 11. Each fastening bolt 11 passes through the two fixing plates 10 and one of the mounting brackets 6 in sequence and is threaded with a nut 12. Through the locking force of the fastening bolts 11 and the nuts 12, the fixing plates 10 and the mounting brackets 6 are firmly fixed, which enhances the overall structural stability. The mounting base 1 has two strip grooves 14 inside, and each strip groove 14 is threaded with two fixing bolts 15.

[0024] The working principle of this utility model is as follows: During assembly, the connecting rod 205 and the movable block 203 are moved by pulling the insulating block 207, causing the telescopic rod 201 to retract and the spring 202 to compress. The insertion rod 206 slides along the slide groove 3 with the movable block 203 and exits the slot 5. The mounting bracket 6 with the iron core 9 is slid into the mounting base 1 along the slot 4. The insulating block 207 is released, the spring 202 returns to its original position, and the telescopic rod 201 extends. The insertion rod 206 is re-engaged into the slot 5, achieving rapid fixation of the iron core 9. Subsequently, the two mounting brackets 6 are securely connected by two fixing plates 10 in conjunction with fastening bolts 11 and nuts 12. The insulating plate 7 isolates the coil 8 from the mounting bracket 6 to ensure electrical safety. The wiring terminal 13 is used for the circuit connection of the coil 8. Finally, the entire mounting base 1 is fixed to the external equipment or bracket by the fixing bolts 15 in the strip groove 14, completing the overall assembly.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
