Description

Technical Field

[0001] The utility model relates to the technical field of reactors, and specifically relates to a three-phase water-cooled iron-core reactor. Background Technique

[0002] A reactor, also called an inductor, is widely used in circuits. In a circuit, due to the effect of electromagnetic induction, there is a certain inductance, which can play a role in preventing current changes. When a conductor is energized, a magnetic field will be generated within a certain space it occupies. Therefore, all current-carrying conductors have inductance in a general sense. However, the inductance of a straight energized conductor is small, and the generated magnetic field is not strong. Therefore, an actual reactor is a wire wound in the form of a solenoid, called an air-core reactor; sometimes, in order to make this solenoid have a larger inductance, an iron core is inserted into the solenoid, called an iron-core reactor.

[0003] When the reactor works for a long time, a large amount of heat will be generated inside it. If the reactor works in a high-temperature environment for a long time, its service life will be reduced. Therefore, it is necessary to cool the inside of the reactor in time. The prior art, such as a water circuit pipeline of a water-cooled reactor in a Chinese patent, publication number: CN203205200U, realizes timely cooling of the inside of the reactor by setting a water distributor and water-cooled plates on the reactor. However, the disadvantage of this patent is that both the cooling water and the return water have to pass through the water distributor, and the temperature of the return water is higher than that of the cooling water, which causes heat exchange between the return water and the cooling water, increasing the temperature of the cooling water and thus reducing the water-cooling efficiency. Therefore, it is necessary to further upgrade the water-cooled reactor. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a three-phase water-cooled iron-core reactor, which can improve the working performance of the reactor.

[0006] Preferably, an inlet water flow channel and an outlet water flow channel are opened along the length direction of the water distribution plate; both the inlet water flow channel and the outlet water flow channel are communicated with the water-cooling flow channels of each water-cooled plate.

[0007] Preferably, the inlet water flow channel has a structure of one inlet and two outlets; the outlet water flow channel has a structure of two inlets and one outlet; a plurality of water-cooled plates are connected in series through hoses.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice the present invention. Although the present invention is described in connection with its preferred specific embodiments, these embodiments are only illustrative and do not limit the scope of the present invention.

[0023] Specific Embodiment 1: Please refer to Figures 1-5 A three-phase water-cooled iron core reactor, comprising: a reactor body and a water distribution plate 5, six water-cooled plates 6 and a plurality of hoses 8 provided on the reactor body for heat dissipation. The six water-cooled plates 6 are disposed on both sides of the water distribution plate 5 and are connected to the water distribution plate 5 through the hoses 8. Cooling water is split by the water distribution plate 5 to each water-cooled plate 6, exchanges heat with the reactor body, and then returns to the water distribution plate 5 for discharge, improving the working performance of the reactor.

[0024] The reactor body is a three-phase reactor, comprising an iron core 1, two sets of clamping members 2, three windings 3, six outgoing busbars 4 and a plurality of fasteners. The two sets of clamping members 2 are respectively disposed at the front end and the rear end of the iron core 1 through the fasteners. The windings 3 are sleeved on the iron columns of the iron core 1, and two outgoing busbars 4 are provided for each winding 3.

[0025] The clamping member 2 comprises a top plate 21, a bottom plate 22 and two connecting plates 23. The top plate 21 is disposed on the upper side of the bottom plate 22, and the two are fixedly connected through the two connecting plates 23.

[0026] This iron core reactor further comprises a bracket, which is fixedly disposed on the clamping member 2 located on the front side of the iron core 1; the water distribution plate 5 is disposed on the upper side of the iron core 1 through the bracket; an inlet water channel 51 and an outlet water channel 52 are formed on the water distribution plate 5 along its length direction. The inlet water channel 51 has a structure of one inlet and two outlets, while the outlet water channel 52 has a structure of two inlets and one outlet. That is to say, both the inlet water channel 51 and the outlet water channel 52 each comprise three ports, and the ports of the inlet water channel 51 and the outlet water channel 52 are all located on the outer periphery of the water distribution plate 5 body; two fixing through holes 53 are also longitudinally formed on the water distribution plate 5, and the through holes 53 are located between the inlet water channel 51 and the outlet water channel 52; during implementation, the fasteners pass through the through holes 5 and are connected to the bracket, keeping the water distribution plate 5 fixed.

[0027] In this embodiment, in order to reduce the heat exchange between the inlet water channel 51 and the outlet water channel 52, the water distribution plate 5 can be made of plastic material.

[0028] Each winding 3 is configured with two water-cooling plates 6. During implementation, the water-cooling plates 6 are embedded inside the winding 3, so that the outer periphery of the water-cooling plates 6 can fully contact the winding 3, improving the efficiency of heat exchange; a U-shaped water-cooling channel 61 is provided inside the water-cooling plate 6. In other embodiments, the water-cooling channel 61 can also be a continuously curved serpentine structure; a screw hole 62 is further provided at the upper end of the water-cooling plate 6; the screw hole 62 and the two ports of the water-cooling channel 61 are located on the same side; the water-cooling plate 6 is made of a metal material.

[0029] During implementation, the two outlets of the water inlet channel 51 are respectively connected to the water-cooling plates 6 on both sides of the water distribution plate 5, and the two inlets of the water outlet channel 52 are respectively connected to the water-cooling plates 6 on both sides of the water distribution plate 5. At the same time, the water-cooling channels 61 of the water-cooling plates 6 on the same side are connected in series through a hose 8.

[0030] In other embodiments, in order to make the heat dissipation of the reactor more balanced, while increasing the cooling water flow rate, each water-cooling plate 6 can be respectively connected to the water distribution plate 5, and the water-cooling plates 6 are in parallel with each other. At this time, the number of the water outlet ports of the water inlet channel 51 and the number of the water inlet ports of the water outlet channel 52 are both the same as the number of the water-cooling plates 6.

[0031] In this embodiment, an insulating sleeve 7 is further sleeved on the outer periphery of each water-cooling plate 6.

[0032] In order to reduce the interference of the water-cooling plate 6 to the reactor body and improve the stability and reliability of the reactor, this iron core reactor further includes a number of connecting wires 9. Six water-cooling plates 6 are connected to the clamping piece 2 through the connecting wires 9. The connecting wires 9 and the water-cooling plates 6 are fixedly connected by bolts, and the bolts are arranged in the screw holes corresponding to the water-cooling plates 6; during use, the bottom plate of the clamping piece 2 is grounded.

[0033] Through this technical solution, by arranging a water distribution plate, water-cooling plates and hoses on the reactor body, the water-cooling plates are placed inside the windings on both sides of the water distribution plate and connected to the water distribution plate through hoses. After the cooling water is split by the water distribution plate to each water-cooling plate and exchanges heat with the reactor body, it flows back to the water distribution plate and is discharged. The water distribution plate is made of plastic material. Through such an upgrade, the working performance of the reactor can be improved.
