Description

TECHNICAL FIELD

[0002] As an important electrical device, mutual inductors are widely used in power systems to realize the transformation and transmission of voltage, current and other electrical quantities. The stability and reliability of their performance are directly related to the safe operation of the power system.

[0003] In the manufacturing process of mutual inductors, the glue pouring operation is an indispensable link. The main purpose of glue pouring is to protect the coils and other key components inside the mutual inductor, prevent environmental factors (such as moisture, dust, etc.) from causing damage, and improve the mechanical strength and insulation performance of the mutual inductor.

[0004] However, in the existing mutual inductor glue pouring technology, there are some problems to be solved. First, the existing technology often ignores the preheating of the mutual inductor during the glue pouring operation. Since the glue used in the glue pouring process usually needs to be hot-melted, if the hot-melted glue is directly injected into the mutual inductor without preheating, a large temperature difference will occur between the glue and the mutual inductor and its internal coils. This temperature difference may cause uneven shrinkage during the cooling and shrinkage of the glue, thereby generating internal stress, which may even cause the mutual inductor to crack, affecting its performance and service life.

[0005] Secondly, the existing technology lacks effective means to remove the residual bubbles or voids inside the mutual inductor after glue pouring. These bubbles or voids not only reduce the density of the glue pouring and affect the insulation performance and mechanical strength of the mutual inductor, but also may become potential fault points, threatening the safe operation of the power system.

The plurality of mutual inductors 12 are placed at the top end of the rotating aluminum plate 81 along the circumference at equal intervals. The rotating aluminum plate 81 serves as a basic rotating platform for bearing the mutual inductors 12 and is rotatably arranged at the top end of the heating base 1 through a bearing, so as to ensure smooth rotation under the action of the driving device. The plurality of air holes 2 are located below the rotating aluminum plate 81, so that the steam can uniformly act on the mutual inductors placed on the rotating aluminum plate 81 and provide a suitable temperature environment for the mutual inductors. The outer wall top end of the driving ring 84 is arranged on the inner wall of the rotating aluminum plate 81. The inner wall of the driving ring 84 is provided with a plurality of driving grooves 85 along the circumference at equal intervals. The inner wall of the driving ring 84 is also provided with a plurality of positioning grooves 86 along the circumference at equal intervals. The positions of the plurality of positioning grooves 86 correspond to the positions of the plurality of mutual inductors 12 one by one. The number of the driving grooves 85 is the same as that of the positioning grooves 86. The driving ring 84 plays a role in transmitting rotating power. The motor 87 is screw-connected to the middle part of the top end of the heating base 1. The motor 87 is a prior art. The motor 87 is a servo motor. The motor 87 is connected with a servo controller, which will not be described in detail here. The motor 87 provides energy for the whole rotating mechanism, drives the rotating rod 88 to rotate, and further drives other components to rotate, so as to realize the rotating function of the mutual inductors 12. The rotating rod 88 is locked on the output end of the motor 87 through a shaft coupling. The driving disc 89 is arranged on the outer wall top of the rotating rod 88. The driving disc 89 is matched with the positioning grooves 86 and the driving grooves 85. The driving disc 89 realizes power transmission by cooperating with the driving grooves 85, so as to make the driving ring 84 rotate. At the same time, the driving disc 89 cooperates with the positioning grooves 86 to control the mutual inductors during the rotating process, so as to ensure the accuracy and stability of the rotation of the mutual inductors 12. The number of the limiting plates 82 is a plurality. The plurality of limiting plates 82 are arranged on the top end of the rotating aluminum plate 81 along the circumference at equal intervals. The plurality of mutual inductors 12 are respectively and adaptively inserted into the inner cavities of the plurality of limiting plates 82.

The number of the positioning columns 83 is a plurality. The plurality of positioning columns 83 are arranged on the top end of the rotating aluminum plate 81 along the circumference at equal intervals. The plurality of positioning columns 83 are respectively and adaptively inserted into the inner cavities of the plurality of mutual inductors 12. The positioning columns 83 can further fix the positions of the mutual inductors, prevent the mutual inductors from shaking during the rotating, and also play a role in positioning and guiding during the installation of the mutual inductors, so as to ensure the accuracy of the installation positions of the mutual inductors.

[0035] More specifically, when the transformer 12 needs to be driven to rotate, the motor 87 is started, and its output end drives the driving disc 89 to rotate through the rotating rod 88; when the driving disc 89 is engaged with the driving groove 85 on the inner wall of the driving ring 84, the driving force is transmitted to the rotating aluminum plate 81 through the driving ring 84, driving the rotating aluminum plate 81 and the transformer 12 at the top to rotate synchronously; when the driving disc 89 is engaged with the positioning groove 86, the driving ring 84 and the rotating aluminum plate 81 stop rotating, and at this time, the transformer 12 at the current position is just aligned with the glue pouring gun 13 or the exhaust mechanism 9, achieving precise positioning; through the alternating cooperation of the driving disc 89 and the driving groove 85 and the positioning groove 86, the rotating mechanism 8 can drive the transformer 12 to complete intermittent rotation, ensuring that each transformer 12 completes the preheating, glue pouring, exhaust and other processes in turn, realizing continuous processing.

[0036] Specifically, the exhaust mechanism 9 comprises a bracket 91, a sliding groove 92, a guide rod 93, an electric telescopic rod 94, a sliding block 95, a sealing cover 96 and a vacuum pump 97. The bracket 91 is arranged at the top end of the heating base 1. The outer side of the bracket 91 is provided with the sliding groove 92 in the up-down direction. The bracket 91 serves as the basic support structure of the exhaust mechanism, provides mounting positions and support for other components, guarantees the stability and reliability of the entire exhaust mechanism, enables each component to work normally at the appropriate position, and prevents the sliding block 95 from deviating or shaking during the sliding process. The two guide rods 93 are arranged at the left and right ends of the inner cavity of the sliding groove 92. The guide rods 93 serve to guide and stabilize the sliding block 95, guarantee the smooth sliding of the sliding block 95 in the sliding groove 92, and make the lifting process of the sealing cover 96 more stable. The sliding block 95 is slidably and adaptively connected to the inner cavity top end of the sliding groove 92, and is slidably sleeved on the outer wall of the guide rod 93. The sliding block 95 serves as an intermediate component connecting the electric telescopic rod 94 and the sealing cover 96, transmits the telescopic movement of the electric telescopic rod 94 to the sealing cover 96, drives the sealing cover 96 to move linearly along the direction of the sliding groove 92 and the guide rod 93, and realizes the lifting action of the sealing cover 96. The electric telescopic rod 94 is arranged at the top end of the bracket 91, and the bottom end of the electric telescopic rod 94 is slidably extended into the inner cavity of the sliding groove 92. The bottom end of the electric telescopic rod 94 is arranged at the top end of the sliding block 95. The electric telescopic rod 94 is a power source for driving the sealing cover 96 to lift and lower. Through the telescopic movement of the electric telescopic rod 94, the sliding block 95 is driven to slide up and down in the sliding groove 92, thereby realizing the lifting and lowering of the sealing cover 96. The sealing cover 96 is arranged on the outer side of the sliding block 95. The position of the inner cavity of the sealing cover 96 corresponds to the position of the transformer 12. The bottom end of the sealing cover 96 is provided with a sealing rubber ring, so as to prevent the sealing cover 96 from leaking. The inner cavity diameter of the sealing cover 96 is greater than the length of the transformer 12, so as to guarantee that the transformer 12 can be completely accommodated in the inner cavity of the sealing cover 96. When the sealing cover 96 is lowered, the transformer 12 can be completely accommodated in the inner cavity. The vacuum pump 97 is screw-connected to the top end of the bracket 91. The air inlet of the vacuum pump 97 is connected to the inner cavity of the sealing cover 96 through a pipeline. The vacuum pump 97 is a core air extraction component of the exhaust mechanism, which can extract the air in the inner cavity of the sealing cover 96 after being started, form a negative pressure environment, extract the air inside and around the transformer 12, achieve the purpose of exhaust, and improve the quality of transformer glue pouring.

[0037] More specifically, when the rotating mechanism 8 drives the completed filled mutual inductor 12 to rotate to the position corresponding to the sealing cover 96, the exhaust process starts; first, the electric telescopic rod 94 is powered on, and its output end extends downward to push the sliding block 95 to slide vertically downward along the inner cavity of the sliding groove 92 and the outer wall of the guide rod 93; the guide rod 93 limits the sliding block 95 in both directions to ensure that its movement trajectory is stable and has no deviation, thereby synchronously and smoothly lowering the sealing cover 96 fixed to the outer side of the sliding block 95; when the sealing rubber ring at the bottom end of the sealing cover 96 tightly abuts against the top end of the rotating aluminum plate 81, the electric telescopic rod 94 stops working; at this time, the mutual inductor 12 is completely accommodated in the inner cavity of the sealing cover 96 (because the inner cavity diameter of the sealing cover 96 is greater than the length of the mutual inductor 12), and the sealing rubber ring ensures that the inner cavity of the sealing cover 96 forms a closed space to prevent air leakage; then, the vacuum pump 97 starts to perform the air exhaust operation on the inner cavity of the sealing cover 96 through the connecting pipeline to form a negative pressure environment in the closed space; under the action of the negative pressure, the air bubbles or gaps remaining in the mutual inductor 12 after the filling are affected by the pressure difference, and the air in them is forced to be discharged into the inner cavity of the sealing cover 96 and then be sucked away by the vacuum pump 97, thereby completely eliminating the air bubbles or gaps in the mutual inductor 12; after the exhaust is completed, the vacuum pump 97 stops working, the output end of the electric telescopic rod 94 is retracted, and the sliding block 95 and the sealing cover 96 are lifted to reset, thereby preparing for the next filled mutual inductor 12 to enter the exhaust station.

[0038] The working principle is as follows:

[0039] Step one, when in use, the condensate water is transported into the inner cavity of the condensing box 10 through the conveying pipe 11, and after the condensate water in the inner cavity of the condensing box 10 is filled, the cooling water in the inner cavity of the condensing box 10 can flow into the inner cavity of the heating base 1 through the water inlet pipe 3, the electric heating plate 7 is started, and the cooling water in the inner cavity of the heating base 1 is heated by the electric heating plate 7, the high-temperature steam generated after heating will float upward and contact the rotating aluminum plate 81 through the air hole 2, thereby heating the rotating aluminum plate 81, and further heating the mutual inductor 12 placed on the top end of the rotating aluminum plate 81, which can reduce the temperature difference and reduce the stress risk, and at the same time, due to the increase of the temperature in the inner cavity of the heating base 1, the air pressure in the inner cavity of the heating base 1 will increase, and when the air pressure in the inner cavity of the heating base 1 reaches a certain value, the one-way pressure relief valve 6 will be opened under the action of the air pressure, thereby causing the high-temperature steam in the inner cavity of the heating base 1 to flow into the inner cavity of the steam pipe 5, and then flow into the inner cavity of the condensing box 10 through the steam pipe 5, and the high-temperature steam in the inner cavity of the steam pipe 5 is condensed by the condensate water in the inner cavity of the condensing box 10, and the condensed condensate water is discharged through the steam pipe 5 for unified collection and treatment;

[0040] Step two, start the glue gun 13, the current with its position corresponding to the mutual inductor 12 can be used for glue operation, after the completion of the glue, start the motor 87, the output end of the motor 87 is driven by the rotating rod 88 to drive the rotating disc 89, the driving disc 89 can be rotated and the driving groove 85 is combined to promote the driving ring 84 to drive the rotating aluminum plate 81 to rotate, so that the rotating aluminum plate 81 can drive the top of the mutual inductor 12 to rotate, after the driving disc 89 and the driving groove 85 are separated, the driving disc 89 is immediately engaged with the positioning groove 86, so that the driving disc 89 and the positioning groove 86 can be used to limit the driving ring 84, so that the driving ring 84 can be used to limit the rotating aluminum plate 81, at this time, the next mutual inductor 12 can be promoted to correspond to the position of the glue gun 13, so that the glue gun 13 can be used for glue operation on the mutual inductor 12, and the above-mentioned operation can be repeated to realize the continuous glue of the mutual inductor 12.

[0041] Step three, after the completion of the mutual inductor 12 is rotated to the sealing cover 96, the electric telescopic rod 94 is started, the sealing cover 96 is driven by the electric telescopic rod 94 to move downward, until the bottom end of the sealing cover 96 contacts the top end of the rotating aluminum plate 81, at this time, the mutual inductor 12 is completely accommodated in the inner cavity of the sealing cover 96, the vacuum pump 97 is driven, the air in the inner cavity of the sealing cover 96 is pumped out by the vacuum pump 97, so that the bubbles remaining in the mutual inductor 12 are discharged, and the bubbles or gaps remaining after the mutual inductor 12 is glued can be discharged, so that the glue is completed.

[0042] The device effectively solves the problem of internal stress and cracking caused by large temperature difference during glue filling, improves the reliability and service life of the product, and integrates the exhaust mechanism, which can completely remove the bubbles or gaps remaining after glue filling, ensures the glue quality, and reduces the potential failure risk.
