Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a horizontal conjugate water-cooled reactor. Background Art

[0002] Reactors are electrical components in power systems, mainly used to reduce the capacitive load of equipment during operation to improve the equipment's operating efficiency and power quality. Reactors are usually composed of coils and iron cores. Alternating current is passed through the coil to form an electromagnetic field, causing the current to shift in phase.

[0003] The use of reactors will result in the consumption of a large amount of electrical energy. Due to the thermal effect of current, a large amount of heat is generated. If the heat is not dissipated in time, the internal temperature of the reactor will be too high, damaging the equipment and causing system failures, affecting the stability of the system and the quality of power.

[0004] In the prior art, there are many options for heat dissipation of reactors. According to the characteristics of the equipment and the use environment, most of them adopt natural ventilation, forced ventilation and water cooling. Natural ventilation heat dissipation is relatively simple, but the efficiency is not high and the temperature cannot be controlled. Forced ventilation and water cooling equipment are more complicated, but they can effectively control the temperature of the reactor and improve the heat dissipation efficiency.

[0049] As attached Figure 1 As shown, in an illustrative embodiment of a horizontal conjugate water-cooled reactor of the utility model, it includes:

[0050] The coil package includes three coils, which are defined as A, B, and C phases in sequence along the horizontal direction. Each phase coil package includes an iron core 1, a coil 2, an iron core heat sink 3, and a coil heat sink 4;

[0051] The coil 2 is sleeved on the outside of the same-phase iron core 1; each coil 2 is provided with a heat dissipation slot 401; the iron core heat dissipation plate 3 is fitted and installed at the intersection of the iron core 1 and the coil 2; the coil heat dissipation plate 4 is embedded and installed in the heat dissipation slot 401;

[0053] In this embodiment, multiple cooling pipes 703 are connected in parallel to the bus to reduce water resistance. Cooling water is introduced into one end of the bus. The cooling water flows through each core heat sink 3 and each coil heat sink 4 along the cooling pipe 703, and finally flows out from the other end of the bus to achieve heat dissipation of the reactor.

[0054] To improve the heat dissipation efficiency, in some embodiments, a plurality of heat dissipation slots 401 are provided in the same phase coil, and a coil heat dissipation plate 4 is provided in each heat dissipation slot 401.

[0057] The first coil 201 is arranged at the first end of the wire package, and the second coil 202 is arranged at the second end of the wire package;

[0060] The second end terminal row 503 is disposed at the second end of the second coil 202 .

[0061] In this embodiment, the first incoming line board surface 5011 is an electrical connection end, and two coils use one starting terminal block, thereby avoiding the additional connection of the incoming line busbar.

[0065] The reactor also includes:

[0066] The conjugate core block 8 is disposed in the cavity and connected to the core of the adjacent coil.

[0067] In this embodiment, the reactor is configured as a conjugate reactor, so that each phase line package becomes a whole, and the structural strength is higher.

In this embodiment, cooling water flows into the first busbar 701 through the water inlet, and the first busbar flows the cooling water into the connected cooling pipelines respectively, and flows into each coil heat sink 4 and the iron core heat sink 3 through the water inlet nozzle. After absorbing heat, the cooling water flows out through the water outlet nozzle, merges into the second busbar 702, and finally flows out of the reactor through the water outlet to reduce the heat generated by the reactor.

[0069] In some embodiments, it also includes:

[0070] The busbar mounting clamp 704 is mounted on the side surface of the A-phase wire package, and the busbar mounting clamp 704 is made of insulating material. The first busbar 701 and the second busbar 702 are both mounted on the outside of the busbar mounting clamp 704. The busbar mounting clamp 704 is made of insulating material to improve the safety performance of the water cooling process and prevent safety hazards caused by water and electricity leakage.

[0074] The conjugate assembly pull rod 803 connects the conjugate upper clamp 801 and the conjugate lower clamp 802 .

[0075] Preferably, the conjugate upper clamp 801, the conjugate lower clamp 802, and the conjugate assembly rod 803 may be made of platinum, and this fastening method can be used to strengthen the connectivity between each phase coil and improve the overall structural strength of the reactor.

[0076] In some embodiments, it also includes:

[0078] The second yoke piece 902 is arranged opposite to the first yoke piece 901 and connected to the second end of the iron core of each phase coil;

[0079] Two upper clamps 903 are symmetrically arranged and are respectively installed above the first yoke piece 901 and the second yoke piece 902;

[0080] Two bases 904 are symmetrically arranged and respectively installed below the first yoke piece 901 and the second yoke piece 902;

[0081] Assemble the pull rod 905 to connect the upper clamp 903 and the base 904 on the same side.

[0082] In this embodiment, the conjugate reactor is configured as a horizontal solution, which effectively saves the size in the height direction. At the same time, the outer side of the reactor is fastened by the upper clamp 903, the base 904 and the assembly rod 905, which effectively improves the structural strength.
