Description

Technical Field

[0001] This utility model relates to the field of reactor technology, and in particular to a magnetically controlled reactor. Background Technology

[0002] Magnetically controlled reactors are reactive power compensation devices based on the principle of magnetic saturation. They achieve continuous and smooth adjustment of reactance by changing the core permeability through regulating the DC excitation current. Their core advantages lie in their fast dynamic response (millisecond-level) and low harmonic pollution, making them a viable alternative to traditional fixed reactors or staged switching devices, thus avoiding voltage transients. This technology, combined with power electronic control and thyristor-regulated excitation, adapts to the real-time reactive power requirements of the power grid. It is widely used in new energy grid connection, industrial load compensation, and power grid voltage stabilization scenarios, and is one of the key components of flexible AC transmission systems.

[0003] The existing magnetic valve type reactor does not have a heat dissipation structure during operation. Heat easily accumulates inside the reactor during use. The reactor operates at high temperature for a long time, which can accelerate the aging of internal components and greatly reduce the service life of the reactor. Based on this, the present invention is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a magnetically controlled reactor that can overcome or at least partially solve the above problems.

[0013] Compared with the prior art, this utility model provides a magnetically controlled reactor, which has the following advantages:

[0014] 1. This magnetically controlled reactor uses a water circuit consisting of two types of fans and a circulating copper pipe to dissipate heat from the reactor column through two heat dissipation methods, thereby increasing the heat dissipation effect.

[0015] 2. This magnetically controlled reactor can drive two fans and a gear pump simultaneously through a servo motor. It has a simple structure and is not easily damaged.

[0016] 3. This magnetically controlled reactor, by setting up air inlet pipes and air inlet holes, can carry away the dust on the heat-conducting plate during heat dissipation, thus avoiding excessive dust accumulation on the heat-conducting plate and reducing the heat dissipation effect.

[0024] 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.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1:

[0027] Reference Figures 1-5 A magnetically controlled reactor includes a base 1, and further includes: a reactor body 2 fixedly connected to the base 1, and a top beam 12 fixedly connected above the reactor body 2; a heat-conducting plate 21 fixedly connected to the reactor body 2, and a circulating copper pipe 22 fixedly connected to the heat-conducting plate 21; an air inlet pipe 41 fixedly connected to the heat-conducting plate 21, and an air inlet hole 411 opened on the air inlet pipe 41, the air inlet hole 411 corresponding to the position of the heat-conducting plate 21; a cooling fan 33 fixedly connected to the base 1, and an exhaust fan 34 fixedly connected above the cooling fan 33.

[0028] Unlike common heat dissipation methods, this invention features two types of fans and a circulating copper pipe 22. The circulating copper pipe 22 forms a circulating water circuit, allowing the coolant inside to carry the heat from the heat-conducting fins 21 to the cooling fan 33. The cooling fan 33 then blows the coolant to cool it down. The exhaust fan 34 generates airflow in the opposite direction to the cooling fan 33. The exhaust fan 34 draws in heat from the heat-conducting fins 21 through the air inlet duct 41 and exhausts it through the air inlet vent 411. This double-layer heat dissipation method increases the heat dissipation effect. At the same time, dust that usually falls on the heat-conducting fins 21 is also drawn away through the air inlet vent 411, preventing accumulated dust from affecting the heat dissipation effect. Each air inlet vent 411 corresponds to each heat-conducting fin 21, thus absorbing heat and dust from the heat-conducting fins 21 in the most direct way.

[0029] Example 2:

[0030] Reference Figures 1-5 The embodiment is basically the same as that in Example 1, but with a further improvement: a servo motor 3 is fixedly connected to the base 1, a drive gear 31 is fixedly connected to the output end of the servo motor 3, a first rotating shaft 311 is fixedly connected to the drive gear 31, the first rotating shaft 311 is fixedly connected to the rotating shaft of the cooling fan 33, a second rotating shaft 322 is fixedly connected to the rotating shaft of the exhaust fan 34, a driven gear 32 is fixedly connected to the other end of the second rotating shaft 322, the drive gear 31 and the driven gear 32 mesh, a gear pump 23 is fixedly connected to the base 1, the drive gear in the gear pump 23 is fixedly connected to the rotating shaft of the cooling fan 33, the gear pump 23 is connected to the circulating copper pipe 22, a heat dissipation pipe 4 is fixedly connected to the base 1, the heat dissipation pipe 4 is connected to the cooling fan 33, the gear pump 23 is located inside the heat dissipation pipe 4, the exhaust fan 34 is connected to the air inlet pipe 41, the other side of the exhaust fan 34 is fixedly connected to the exhaust pipe 42, and a mounting beam 11 is fixedly connected to the bottom of the base 1.

[0031] The reactors corresponding to this utility model are usually installed in the reactive power compensation complete set of equipment cabinets or independent cabinets in low-voltage / medium-voltage power distribution rooms. The servo motor 3 can drive the drive gear 31 and the cooling fan 33 to rotate in the forward direction. At the same time, it can also drive the drive gear in the gear pump 23 to rotate, thereby driving the gear pump 23 to run, which in turn makes the coolant in the circulating copper pipe 22 flow and circulate. When the drive gear 31 rotates, it will also drive the driven gear 32 to rotate in the reverse direction, thereby driving the exhaust fan 34 to rotate in the reverse direction.

[0032] The gear pump 23 is placed in the heat dissipation pipe 4. The channels on both sides of the heat dissipation pipe 4 are connected to the outside of the cabinet. The cooling fan 33 directly blows the gear pump 23 and a section of circulating copper pipe 22 connected to the gear pump 23 to cool them down. The hot air is discharged to the outside through the heat dissipation pipe 4 on both sides, thereby achieving the effect of cooling the coolant in the gear pump 23 and the circulating copper pipe 22.

[0033] The exhaust duct 42 is connected to the outside of the cabinet. The exhaust fan 34 draws in the heat and dust on the heat conduction plate 21 through the air inlet 411 and then discharges them to the outside through the air inlet duct 41 and the exhaust duct 42.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
