Description

Technical Field

[0001] This utility model belongs to the field of reactor technology, and in particular relates to a three-phase dry reactor. Background Technology

[0002] A three-phase dry-type reactor is an electrical component used in power systems. It is mainly used to compensate for inductive loads in power systems and reduce voltage fluctuations in the system. By adding a three-phase dry-type reactor to the circuit, the power system can be effectively compensated and the system stability can be improved.

[0003] The existing three-phase dry-type reactors are mainly composed of an iron core and coils. The coils are assembled with the iron core column and fixed by end pads. The upper and lower ends of the coils are also equipped with clamps. The iron core column is fixed as a whole by screws and upper and lower iron yoke clamps. The iron core coils are usually provided with three sets.

[0004] The three sets of iron core coils of this existing three-phase dry reactor are usually fixed between the same upper and lower clamps. When one set of iron core coils is replaced, the entire three-phase dry reactor needs to be removed and replaced, which results in high maintenance and replacement costs. Utility Model Content

The reactor body includes a coil body. Upper clamps are installed on the upper left and right sides of the coil body through bolt assemblies. Lower clamps are installed on the lower left and right sides of the coil body through bolt assemblies. The connecting component assembly includes a U-shaped seat. Two U-shaped seats are arranged vertically opposite each other. Each U-shaped seat has symmetrically arranged embedded holes on one side. A U-shaped frame is integrally provided on the right side of each U-shaped seat. A pull screw is arranged through the two U-shaped frames. The two ends of the pull screw are fixed to the U-shaped frame by nuts.

[0007] Preferably, the upper and lower U-shaped seats are fixedly installed on the outside of the upper clamp and the outside of the lower clamp respectively by bolts and nuts.

[0008] Preferably, the recessed hole is used to accommodate the nut component in the bolt and nut assembly.

[0010] Preferably, the horizontal section of the lower clamp is also symmetrically provided with mounting holes.

[0011] Preferably, the mounting hole is for passing through the bolt in the bolt and nut.

[0020] The present invention will now be described in detail with reference to the accompanying drawings:

[0021] As shown in Figures 1 and 3, the three-phase dry reactor of this utility model includes a reactor body 1 and a connecting component assembly 2 installed with the reactor body 1. The reactor body 1 includes a coil body 11. Upper clamps 12 are installed on the left and right sides of the upper end of the coil body 11 through bolt assemblies 13, and lower clamps 14 are installed on the left and right sides of the lower end of the coil body 11 through bolt assemblies 13.

[0022] In this implementation plan, in conjunction with the appendix Figure 2As shown, the connector assembly 2 includes a U-shaped seat 21, with two U-shaped seats 21 arranged vertically opposite each other. Each U-shaped seat 21 has a symmetrically arranged recessed hole 22 on one side. Each U-shaped seat 21 has an integrally arranged U-shaped frame 23 on its right side. A pull screw 24 is arranged through the two U-shaped frames 23. The two ends of the pull screw 24 are fixed to the U-shaped frame 23 by nuts 25. When installing multiple reactor bodies 1, the user can install or remove the upper and lower U-shaped seats 21 from the upper clamp 12 and the lower clamp 14 to splice or disassemble the reactor bodies 1. The pull screw 24 serves to reinforce the upper and lower U-shaped seats 21 and reduce the deformation of the upper clamp 12 and the lower clamp 14.

[0023] In this embodiment, specifically, the upper and lower U-shaped seats 21 are fixedly installed on the outside of the upper clamp 12 and the outside of the lower clamp 14 respectively by bolts and nuts 26.

[0024] In this embodiment, specifically, the embedded hole 22 is used to accommodate the nut component in the bolt and nut 26.

[0025] In this embodiment, specifically, the horizontal section of the upper clamp 12 is symmetrically provided with mounting holes.

[0026] In this embodiment, specifically, the horizontal section of the lower clamp 14 is also symmetrically provided with mounting holes.

[0027] In this embodiment, specifically, the mounting hole is used to pass through the bolt in the bolt nut 26.

[0028] In this utility model, when installing the reactor body 1, the user assembles the reactor bodies 1 placed side by side using the connecting component 2. When disassembling, the reactor body 1 that needs to be replaced can be replaced individually by removing the connecting component 2, saving replacement and maintenance costs. The user assembles the three sets of reactor bodies 1 and connects them to external wiring to form a three-phase reactor.
