[0032] See also Figure 1 , which is a structural diagram of an industrial power transformer according to an embodiment of the present invention.

[0033] An industrial power transformer 10 of an embodiment includes a mounting base 100 and a transformer assembly 200. Figure 2The mounting base 100 includes a base body 110 and a glue-filled separation ring column 120 that are interconnected. The base body 110 is provided with a glue-filled space 102, and the glue-filled separation ring column 120 is arranged in the glue-filled space 102. The transformer assembly 200 includes a transformer conversion component 210 and a transformer transmission component 220. The transformer conversion component 210 is arranged in the glue-filled space 102, the primary side of the transformer conversion component 210 is used to connect to the industrial voltage, and the secondary side of the transformer conversion component 210 is electrically connected to the transformer transmission component 220. The transformer transmission component 220 is connected to the mounting base 100, and the transformer transmission component 220 covers the glue-filled space 102. Among them, the voltage-changing transmission component 220 is provided with a glue injection hole 202 and a glue injection full inspection hole 204. The glue injection hole 202 is used to inject thermal conductive fixing glue into the glue injection space 102. The glue injection full inspection hole 204 is arranged corresponding to the center of the glue injection full separation ring column 120.

[0034] In this embodiment, when pouring glue, after the thermal conductive fixing glue in the glue pouring space 102 is filled to a sufficient amount, the glue filling inspection hole 204 is used to observe the filling situation of the thermal conductive fixing glue. When the thermal conductive fixing glue enters the glue pouring separation ring column 120 and fills it, it indicates that the glue pouring space 102 is full of glue. There is no need to continue pouring glue, which effectively ensures that the glue is poured in a sufficient amount and avoids insufficient or excessive thermal conductive fixing glue.

[0035] In one embodiment, see Figure 2 The glue injection hole 202 is located away from the glue filling inspection hole 204, and the projection of the glue filling separation ring 120 on the voltage conversion component 210 is offset from the glue injection hole 202. In this embodiment, the glue injection hole 202 serves as a pouring port for the thermally conductive fixing glue, that is, the thermally conductive fixing glue is poured into the glue injection space 102 through the glue injection hole 202. The glue injection hole 202 is arranged away from the glue filling inspection hole 204, so that the glue injection hole 202 is away from the center position of the glue filling separation ring column 120, thereby making the glue injection hole 202 and the center of the glue filling separation ring column 120 misaligned. Specifically, the projections of the glue injection hole 202 and the glue filling separation ring column 120 on the voltage transformer 210 do not overlap, ensuring that the thermal conductive fixing glue injected from the glue injection hole 202 is located outside the glue filling separation ring column 120, which is convenient for fixing the voltage transformer 210 in the glue injection space 102, thereby avoiding glue injection into the glue filling separation ring column 120.

[0036] In one embodiment, see Figure 2The base body 110 includes a mounting portion 112 and a heat dissipation portion 114 that are interconnected. The voltage conversion component 210 is housed in the mounting portion 112. The heat dissipation portion 114 is located on the side of the mounting portion 112 that is away from the voltage transmission component 220. The heat dissipation portion 114 is also in contact with the voltage conversion component 210. In this embodiment, the mounting portion 112 serves as a receiving component for the voltage conversion component 210, that is, the voltage conversion component 210 is housed in the mounting portion 112 to facilitate the installation and fixation of the voltage conversion component 210. The heat dissipation portion 114 is connected to the mounting portion 112. The heat dissipation portion 114 dissipates the heat generated by the voltage conversion component 210 in the mounting portion 112, allowing the heat on the voltage conversion component 210 to be dissipated into the air, thereby improving the heat dissipation performance of the voltage conversion component 210.

[0037] Further, see Figure 3 The heat dissipation portion 114 is provided with a plurality of heat dissipation slots 104 for dissipating heat from the voltage conversion element 210. In this embodiment, the heat dissipation slots 104 are provided on the surface of the heat dissipation portion 114. The heat dissipation slots 104 increase the surface area of ​​the heat dissipation portion 114, thereby increasing the contact area between the heat dissipation portion 114 and the air, thereby further improving the heat dissipation performance of the heat dissipation portion 114.

[0038] Furthermore, the heat dissipation unit has a heat dissipation circulation channel that communicates with the outside to introduce a heat dissipation medium into the heat dissipation unit. In this embodiment, the heat dissipation circulation channel is located within the heat dissipation unit and flows with a heat dissipation medium. Specifically, the heat dissipation medium is cooling water. Cooling water flows through the heat dissipation circulation channel. After the voltage conversion element generates heat, the cooling water in the heat dissipation circulation channel removes the heat transferred from the heat dissipation unit. In other words, the cooling water and the heat dissipation unit exchange heat, allowing the heat from the voltage conversion element to be removed through the cooling water, effectively improving the heat dissipation performance of the industrial power transformer.

[0039] For further information, see Figure 2The heat dissipation portion 114 includes a heat dissipation main body 114a and a heat dissipation cover plate 114b that are interconnected. The heat dissipation main body 114a is provided with a heat dissipation groove 106, and the heat dissipation cover plate 114b covers the opening of the heat dissipation groove 106 to form the heat dissipation circulation channel. In this embodiment, the heat dissipation groove 106 is provided on the heat dissipation main body 114a, and the heat dissipation cover plate 114b is connected to the heat dissipation main body 114a. The heat dissipation cover plate 114b covers the heat dissipation groove 106 to form a heat dissipation circulation channel for placing the heat dissipation medium to prevent the heat dissipation medium from leaking out. In another embodiment, the heat dissipation main body 114a is provided with a liquid inlet and a liquid outlet that are connected to the heat dissipation groove 106. The liquid inlet is used to communicate with the liquid inlet pipe, and the liquid outlet is used to communicate with the liquid outlet pipe, so as to facilitate the circulation of the heat dissipation medium.

[0040] Further, see Figure 2 The heat dissipation portion 114 further includes a sealing rubber ring 114c, which is disposed between the heat dissipation main portion 114a and the heat dissipation cover plate 114b. In this embodiment, the sealing rubber ring 114c is connected to the heat dissipation main portion 114a and the heat dissipation cover plate 114b, respectively. That is, the sealing rubber ring 114c is disposed between the heat dissipation main portion 114a and the heat dissipation cover plate 114b. The sealing rubber ring 114c fills the gap between the heat dissipation main portion 114a and the heat dissipation cover plate 114b, thereby improving the sealing between the heat dissipation main portion 114a and the heat dissipation cover plate 114b, ensuring the stability of the heat dissipation medium in the heat dissipation circulation channel, and further reducing the probability of leakage of the heat dissipation medium.

[0041] In one embodiment, see Figure 2 The voltage conversion component 210 is provided with a limiting hole 206, and at least a portion of the glue-filled separation ring column 120 is passed through the limiting hole 206. In this embodiment, the limiting hole 206 is provided on the voltage conversion component 210, and the glue-filled separation ring column 120 is passed through the limiting hole 206, that is, a portion of the glue-filled separation ring column 120 is located within the limiting hole 206, so that the voltage conversion component 210 is sleeved on the glue-filled separation ring column 120, thereby making the voltage conversion component 210 and the glue-filled separation ring column 120 mutually sleeved, thereby improving the installation stability of the voltage conversion component 210 in the glue-filling space 102.

[0042] In one embodiment, see Figure 3The voltage-transforming transmission element 220 includes a first voltage-transforming output plate 222 and a second voltage-transforming output plate 224, which are spaced apart from each other. The first voltage-transforming output plate 222 is electrically connected to the first end of the secondary side, and the second voltage-transforming output plate 224 is electrically connected to the second end of the secondary side. In this embodiment, the first voltage-transforming output plate 222 is a positive output plate, and the second voltage-transforming output plate 224 is a negative output plate. The first voltage-transforming output plate 222, the second voltage-transforming output plate 224, and the secondary side of the voltage-transforming conversion element 210 form a transformed circuit, facilitating output via the first voltage-transforming output plate 222 and the second voltage-transforming output plate 224. In another embodiment, the transformer transmission element 220 further includes a transformer insulating plate, which is located between the first transformer output plate 222 and the second transformer output plate 224. The transformer insulating plate is used to insulate and separate the first transformer output plate 222 from the second transformer output plate 224 to prevent a short circuit between the first transformer output plate 222 and the second transformer output plate 224.

[0043] In another embodiment, the glue-filled separation ring column has a center hole corresponding to the glue-filled inspection hole, and the aperture of the center hole gradually increases in the direction approaching the voltage transformer transmission component. In this way, when the thermally conductive fixing glue enters the glue-filled separation ring column, the hole wall of the center hole forms a downward sliding slope, which facilitates the rapid guidance of the thermally conductive fixing glue to the bottom of the glue-filled separation ring column, thereby facilitating the timely observation of the thermally conductive fixing glue through the glue-filled inspection hole and the timely stopping of the glue filling.

[0044] In one embodiment, see Figure 4The glue filling separation ring column 120 has a glue filling preview slope 108. The glue filling preview slope 108 is located near the voltage transformation transmission component 220 and is inclined in a direction away from the glue filling inspection hole 204. In this embodiment, the glue filling preview slope 108 is located at the end of the glue filling separation ring column 120 away from the mounting base 100, and the glue filling preview slope 108 corresponds to the glue filling inspection hole 204. The glue filling preview slope 108 is inclined toward the direction away from the glue filling inspection hole 204, so that the glue filling preview slope 108 is toward the glue filling hole 202. In the direction from the glue filling hole 202 to the glue filling inspection hole 204, the distance between the glue filling preview slope 108 and the voltage transformer transmission component 220 gradually increases, that is, the height of the glue filling separation ring column 120 close to the glue filling hole 202 is greater than the height of the glue filling separation ring column 120 away from the glue hole 202. In view of the influence of the flow rate of the thermal conductive fixing glue, the thermal conductive fixing glue on the side of the glue-filled separation ring column 120 close to the glue-filling hole 202 gathers faster, that is, the thermal conductive fixing glue rising rate on the side of the glue-filled separation ring column 120 close to the glue-filling hole 202 is greater than the thermal conductive fixing glue rising rate on the side of the glue-filled separation ring column 120 away from the glue-filling hole 202. When the thermal conductive fixing glue is poured into the glue-filling space 102 through the glue-filling hole 202, the glue-filled separation ring column 120 is filled with a large amount of heat. The thermally conductive fixing glue on the side of the spacer ring column 120 away from the glue filling hole 202 reaches the lowest point of the glue filling preview slope 108 in advance, so that the thermally conductive fixing glue is evenly distributed and sufficient in the glue filling space 102 after standing still, that is, after standing still for a period of time, the liquid level of the thermally conductive fixing glue in the glue filling space 102 is level, and at this time the thermally conductive fixing glue is fully in contact with the voltage transformer 210, ensuring that the thermally conductive fixing glue is evenly in contact with the voltage transformer 210 and the total amount used is not excessive.

[0045] In one embodiment, see Figure 5 The present application also provides a method for filling glue for an industrial power transformer based on any of the above embodiments, and the method includes some or all of the following steps.

[0046] S100: injecting thermally conductive fixing glue into the glue injection hole 202.

[0047] In the embodiment, the glue filling hole 202 is used as an injection port of the pouring heat-conducting fixing glue of the industrial power transformer, the glue filling hole 202 is used for the introduction of the heat-conducting fixing glue, and the heat-conducting fixing glue is poured through the hole away from the glue filling and filling inspection hole 204. On the one hand, the heat-conducting fixing glue is avoided from being poured into the glue filling and filling separation ring column 120 too early, and on the other hand, more heat-conducting fixing glue can be poured into the glue filling space 102, so that the heat-conducting fixing glue in the glue filling space 102 is more fully in contact with the transformer conversion piece 210, to improve the connection stability and heat dissipation performance of the transformer conversion piece 210.

[0048] S200: Obtain a pouring image through the glue filling and filling inspection hole 204.

[0049] In the embodiment, the glue filling and filling inspection hole 204 is correspondingly arranged with the glue filling and filling separation ring column 120. The glue filling and filling separation ring column 120 is observed through the glue filling and filling inspection hole 204. That is, after the heat-conducting fixing glue is poured to a sufficient amount, part of the heat-conducting fixing glue passes over the top of the glue filling and filling separation ring column 120 and enters the column. At this time, the image inside the column is collected through the glue filling and filling inspection hole 204, so as to determine whether the heat-conducting fixing glue enters the glue filling and filling separation ring column 120, thereby determining whether the heat-conducting fixing glue is poured to a sufficient amount, and further facilitating subsequent control of the amount of the heat-conducting fixing glue. The pouring image is an image of the bottom of the glue filling and filling separation ring column 120, which is used to determine whether the heat-conducting fixing glue enters the column, so as to determine whether to continue pouring or stop pouring the heat-conducting fixing glue.

[0050] S300: Determine whether the pouring image matches a preset image.

[0051] In the embodiment, the pouring image is an image of the bottom of the glue filling and filling separation ring column 120, which is used to determine whether the heat-conducting fixing glue exists at the bottom of the glue filling and filling separation ring column 120. The preset image is a standard bottom image. Specifically, the preset image is an image corresponding to the case that the bottom of the glue filling and filling separation ring column 120 is free of the heat-conducting fixing glue. The pouring image and the preset image are matched and detected, so as to detect the case that the heat-conducting fixing glue exists at the bottom of the glue filling and filling separation ring column 120, thereby determining whether the heat-conducting fixing glue is poured at the bottom of the glue filling and filling separation ring column 120, and further determining whether the heat-conducting fixing glue in the glue filling space 102 is full.

[0052] S400: When the pouring image does not match the preset image, stop pouring the heat-conducting fixing glue.

[0053] In this embodiment, the overflow image is an image of the bottom of the glue-filled separation ring column 120, which is used to determine whether there is thermally conductive fixing glue at the bottom of the glue-filled separation ring column 120. The preset image is a standard bottom image. Specifically, the preset image is an image corresponding to when there is no thermally conductive fixing glue at the bottom of the glue-filled separation ring column 120. The overflow image does not match the preset image, indicating that thermally conductive fixing glue has appeared at the bottom of the glue-filled separation ring column 120, which means that the thermally conductive fixing glue in the glue-filled space 102 has entered the glue-filled separation ring column 120, which means that the thermally conductive fixing glue poured into the glue-filled space 102 is sufficient. At this point, the pouring of the thermally conductive fixing glue is completed, and there is no need to continue pouring. It is only necessary to stop injecting the thermally conductive fixing glue to avoid excessive pouring of the thermally conductive fixing glue.

[0054] In the above embodiment, when pouring glue, after the thermal conductive fixing glue in the glue pouring space 102 is filled to a sufficient amount, the glue filling inspection hole 204 is used to observe the filling situation of the thermal conductive fixing glue. When the thermal conductive fixing glue enters the glue pouring separation ring column 120 and fills it, it indicates that the glue pouring space 102 is full of glue. There is no need to continue pouring glue, which effectively ensures that the glue is poured in a sufficient amount and avoids insufficient or excessive thermal conductive fixing glue.

[0055] In one embodiment, detecting whether the overflow image matches a preset image includes detecting whether the overflow image matches an image of the empty bottom of the fully glue-filled separator ring 120. In this embodiment, the preset image is an image of the empty bottom of the fully glue-filled separator ring 120, i.e., the preset image is an image corresponding to a state where there is no thermally conductive adhesive at the bottom of the fully glue-filled separator ring 120. Using this empty bottom image as a standard image facilitates improving the accuracy of determining whether the thermally conductive adhesive has been introduced. In another embodiment, the empty bottom image can be determined based on the intensity of reflected light from the bottom of the fully glue-filled separator ring 120. i.e., when the thermally conductive adhesive has not entered the fully glue-filled separator ring 120, the reflected light intensity of the overflow image is maximum. After the thermally conductive adhesive enters the fully glue-filled separator ring 120, as the amount of thermally conductive adhesive gradually increases, the reflected light intensity of the overflow image gradually decreases. In this way, the presence of the thermally conductive adhesive in the fully glue-filled separator ring 120 can be determined based on the reflected light intensity.

[0056] In one embodiment, the detection of whether the overflow image matches the preset image further includes: when the overflow image matches the preset image, continuing to pour the thermally conductive fixing glue, reacquiring the overflow image and returning to the previous step. In this embodiment, the overflow image is an image of the bottom of the glue-filled separation ring column 120, which is used to determine whether there is thermally conductive fixing glue at the bottom of the glue-filled separation ring column 120. The preset image is a standard bottom image. Specifically, the preset image is an image corresponding to when there is no thermally conductive fixing glue at the bottom of the glue-filled separation ring column 120. The overflow image matches the preset image, indicating that thermally conductive fixing glue has not appeared at the bottom of the glue-filled separation ring column 120, that is, the thermally conductive fixing glue in the glue-filled space 102 has not yet entered the glue-filled separation ring column 120, that is, the thermally conductive fixing glue poured into the glue-filled space 102 is still in the pouring process. At this time, the amount of the thermally conductive fixing glue injected is not enough and needs to be injected further. It is only necessary to stop injecting the thermally conductive fixing glue to avoid excessive injection of the thermally conductive fixing glue.

[0057] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
