Description

Technical Field

[0001] The utility model relates to the technical field of transformer heat dissipation, in particular to an iron core internal heat dissipation component. Background Art

[0002] Dry-type transformers are widely used in high-rise buildings, airports, mechanical equipment and other places. Simply put, dry-type transformers refer to transformers whose cores and windings are not immersed in insulating oil. The safe operation and service life of dry-type transformers depend to a large extent on the safety and reliability of the transformer winding insulation. The insulation damage caused by the excessive temperature of the core is one of the main reasons for the failure of the transformer to work properly. Therefore, it is very important to monitor the operating temperature of the transformer and control its alarm. The core is a ferromagnetic material, which will produce hysteresis loss and eddy current loss, which is the main factor for the heating of the transformer. The current existing heat dissipation method of dry-type transformers is generally to install a fan on the transformer and dissipate the heat of the transformer through the airflow of the fan. However, this method can only dissipate the heat on the surface of the transformer, and the heat of the transformer is dissipated from the inside of the core. The fan can only blow to the surface of the core and winding, so the cooling effect is not obvious. Utility Model Content

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] This embodiment relates to an internal heat dissipation component of an iron core, the overall structure of which is as follows: Figure 1 As shown, it includes a silicon steel sheet group 1, a clamp 2, a winding 3, a crossbeam 4, and a heat dissipation pipe 5.

[0032] The silicon steel sheet group 1 is composed of a plurality of stacked silicon steel sheets, the clamps 2 are clamped on both sides of the silicon steel sheet group 1, the winding 3 is wound around the silicon steel sheet group 1, the crossbeam 4 is fixedly arranged at the bottom of the clamps 2, and the heat dissipation pipe 5 is fixedly arranged between the silicon steel sheet groups 1.

[0033] It is worth mentioning that the silicon steel sheets are fixed by pull rods and nuts after stacking. The clamps 2 are located on both sides of the silicon steel sheet group 1. The pull rods are inserted on the silicon steel sheets. The clamps 2 are composed of clamps. The clamps and silicon steel sheets are fitted together. The clamps are used to clamp the silicon steel sheet group 1 by pull rods and nuts. The winding 3 is a wound coil inserted on the silicon steel sheet group 1. The winding 3 is a common winding 3 of the transformer in the prior art and will not be described here. The crossbeam 4 is located at the bottom of the clamp 2 and the silicon steel sheet group 1 to facilitate the installation of the transformer. The heat dissipation pipe 5 is installed between the stacked silicon steel sheets. Cooling liquid flows in the heat dissipation pipe 5. The heat dissipation pipe 5 is connected to a liquid pump and can also be connected to a water tank. The water tank is not shown in the figure. Such a setting can ensure that the coolant dissipates heat inside the silicon steel sheet group 1, thereby improving the heat dissipation efficiency.

[0034] Based on the above overall introduction, an exemplary structure of the core internal heat dissipation component of this embodiment is as follows: Figure 2 and Figure 3 As shown, the silicon steel sheet group 1 includes a horizontal column 101 and a vertical column 102 installed on the horizontal column 101, and the winding 3 is wound on the vertical column 102. There are two groups of clamps 2, which are respectively located at the upper and lower ends of the silicon steel sheet group 1, and the winding 3 is located between the two groups of clamps 2. A first spacer 6 is provided between the clamps 2 and the winding 3.

[0035] It should be noted that there are two horizontal columns 101, which are located at the upper and lower ends of the vertical column 102. A winding 3 is inserted on each vertical column 102. The horizontal column 101 and the vertical column 102 are both made of stacked silicon steel sheets. The clamping plates of the clamp 2 are respectively clamped on the two horizontal columns 101. The winding 3 is located between the upper and lower clamps 2. The first pad 6 can fix the winding 3. The first pad 6 is respectively set at the upper and lower ends of the winding 3, and the first pad 6 can also accommodate the laying of the heat dissipation pipe 5. The crossbeam 4 is located on the lower clamp 2, and the crossbeam 4 can facilitate the installation of the transformer.

[0036] As a preferred example, Figure 2 As shown, a second pad 7 is provided between the cross beam 4 and the lower clamp 2 of this embodiment. A bolt 8 is screwed on the clamp 2, and the bolt 8 is rotatably connected to the first pad 6. Specifically, the second pad 7 and the first pad 6 have the same function. The second pad 7 ensures that there is a gap between the cross beam 4 and the silicon steel sheet group 1 to facilitate the laying of the heat dissipation pipe 5. The bolt 8 can rotate on the clamp 2. The bolt 8 is used to support the first pad 6 and adjust the position of the first pad 6 to facilitate the first pad 6 to support the winding 3.

[0037] As a preferred embodiment, Figure 3 and Figure 5As shown, in this embodiment, the heat dissipation pipe 5 includes a first longitudinal pipe 501 clamped on the longitudinal column 102, a second longitudinal pipe 502 clamped on the transverse column 101, and a transverse pipe 503 connecting the first longitudinal pipe 501 and the second longitudinal pipe 502. A gap 504 is provided between the silicon steel sheet groups 1, and the first longitudinal pipe 501 and the second longitudinal pipe 502 are arranged between the gaps 504. The transverse pipe 503 is in a C shape and fits with the transverse column 101.

[0038] It should be noted that the first longitudinal pipe 501 is laid on the longitudinal column 102, the second longitudinal pipe 502 is laid on the transverse column 101, the first longitudinal pipe 501 and the second longitudinal pipe 502 are arranged in parallel, and the transverse pipe 503 connects the first longitudinal pipe 501 and the second longitudinal pipe 502, so as to realize the circulation of the coolant in the first longitudinal pipe 501, the second longitudinal pipe 502 and the transverse pipe 503. The first longitudinal pipe 501, the second longitudinal pipe 502 and the transverse pipe 503 are set to be square, so as to increase the contact surface. When the silicon steel sheets are stacked, a gap 504 is left in the middle position, so as to facilitate the laying of the first longitudinal pipe 501 and the second longitudinal pipe 502, and then dissipate heat inside the silicon steel sheet group 1. The purpose of setting the transverse pipe 503 in a C shape is to ensure that the gap 504 between the first longitudinal pipe 501 and the second longitudinal pipe 502 is not affected and avoid being blocked by the transverse pipe 503. The transverse pipe 503 fits with the transverse column 101, and the thickness of the transverse pipe 503 is less than the thickness of the first spacer 6, so as to ensure that the transverse pipe 503 can be laid without being affected by the winding 3.

[0039] Preferably, as Figure 4 and Figure 5 shown, a support bar 9 is provided between the first longitudinal pipe 501 and the second longitudinal pipe 502 in the gap 504 of this embodiment, and a blower 10 for blowing air into the gap 504 is provided on the cross beam 4. The first longitudinal pipe 501 and the second longitudinal pipe 502 are each composed of two, and multiple groups are arranged in the gap 504. The two first longitudinal pipes 501 at the tail are connected by a joint 505.

[0040] Specifically, the support bar 9 is used to support the gap 504 of the silicon steel sheet group 1 to prevent the first longitudinal pipe 501 and the second longitudinal pipe 502 from being squeezed and deformed. The blower 10 can blow into the gap 504, thereby improving the heat dissipation efficiency inside the silicon steel sheet group 1. The first longitudinal pipe 501 and the second longitudinal pipe 502 are combined in pairs. Through the cooperation of the transverse pipe 503 and the joint 505, it is ensured that a loop can be formed between the first longitudinal pipe 501, the second longitudinal pipe 502 and the transverse pipe 503. When a liquid pump is installed, circulation can be realized. The first longitudinal pipe 501 and the second longitudinal pipe 502 can be set in multiple groups according to the lateral distance of the silicon steel sheet group 1, and the longitudinal column 102 can also be set in multiple groups. The two first longitudinal pipes 501 on the tail longitudinal column 102 are connected by a joint 505, so as to connect the first longitudinal pipe 501 and the second longitudinal pipe 502 and form a loop. The two first longitudinal pipes 501 on the head headquarters are connected to the liquid pump, so as to realize circulation.

[0041] The internal heat dissipation component of the iron core in this embodiment ensures that the inside of the iron core can dissipate heat through the arrangement of the heat dissipation pipe 5 and the silicon steel sheet group 1, and ensures that the airflow of the fan 10 can be blown into the inside of the iron core through the arrangement of the gap 504, thereby improving the heat dissipation efficiency of the transformer. The arrangement of the first cushion block 6 and the second cushion block 7 ensures that the cross pipe 503 can be installed at the upper and lower ends of the cross column 101 without being affected by the winding 3 and the cross beam 4. The arrangement of the support bar 9 can prevent the heat dissipation pipe 5 from being squeezed and deformed, and the arrangement of the bolt 8 ensures that the position of the second cushion block 7 can be adjusted, thereby facilitating the installation of the cross pipe 503.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
