Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electronic transformers, and particularly relates to an electronic transformer and a safe sealing structure thereof. BACKGROUND

[0002] An electronic transformer is a kind of static power equipment which combines power electronic conversion technology and high-frequency electric energy conversion technology based on electromagnetic induction principle to realize conversion of electric energy with one power feature into electric energy with another power feature. When water enters the electronic transformer, the electronic transformer may be burnt, and after the electronic transformer is damp, the insulation of the electronic transformer is aged, and there is a safety hazard in use. If dust particles enter the electronic transformer, the dust particles are easily charged, and interference is easily generated when the electronic transformer conducts electricity, and even the electronic transformer is damaged.

[0003] In addition, due to the state limitation of the electronic transformer, the fixed connection mode is unique, and the electronic transformer is not suitable for various environments.

[0004] A patent with an application number CN202410436984.1 discloses a safe sealing electronic transformer, which comprises a magnetic core one, a magnetic core two and an insulating tape, installation barrels one and two are press-fitted between the magnetic core one and the magnetic core two, a primary winding and a secondary winding are respectively wound around the outer surfaces of the installation barrels one and two, a plurality of groups of pins are installed at the bottom of the installation barrel two, and a fixed disc and a middle barrel are fixedly installed between the installation barrels one and two. The above technical solution utilizes the “chimney effect” generated by the flow of hot air in the main exhaust channel to assist the upward exhaust of air, and forms a non-powered “air flow pump” in the inner cavity of the heat dissipation box. The air flow pump generates negative pressure upward in the inner cavity of the heat dissipation box, and can absorb hot air from the sealing space between the middle barrel and the fixed disc, and finally effectively realizes the heat management balance function of the transformer. However, the use state of the electronic transformer cannot be recognized and protected during use.

[0005] When the electronic transformer is used, due to different use environments, the electronic transformer and the sealing assembly are impacted, which affects the connection state of the electronic transformer in the sealing assembly, and with the use of the sealing assembly, the sealing assembly is damaged, thereby interfering with the use of the electronic transformer.

[0006] Therefore, in order to solve the above technical problems, the application provides an electronic transformer and a safe sealing structure thereof. SUMMARY

DETAILED DESCRIPTION

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] like Figure 1 As shown, an electronic transformer includes a transformer assembly 1, which includes a magnetic core 101 and a coil 102 connected to the magnetic core 101. The connection between the magnetic core 101 and the coil 102 is a common connection method, which will not be described in detail here. Connecting plates 103 are respectively connected to opposite ends of the magnetic core 101. The connecting plates 103 protrude from the magnetic core 101 to facilitate the fixed installation of the transformer assembly 1 and ensure that the transformer assembly 1 will not detach during use.

[0033] To facilitate electrical connection between external cables and transformer assembly 1, multiple conductive pins 1031 are connected to both connecting plates 103. The conductive pins 1031 are located on the surface of the connecting plate 103 and are connected to the magnetic core 101 and the coil 102, which facilitates the normal use of the electronic transformer.

[0034] When in use, first connect the connecting plate 103 to the area where it needs to work to ensure that the transformer assembly 1 will not move during use. Then connect the circuit that needs to be adjusted to the conductive pin 1031 so that the circuit that needs to be adjusted can be adjusted to a suitable voltage value after passing through the transformer assembly 1.

[0035] Example 2

[0036] like Figure 2 - Figure 7 As shown, a safety sealing structure for use in electronic transformers is disclosed. The safety sealing structure covers the transformer assembly 1 to ensure the stability and safety of the transformer assembly 1 during use. It includes a sealing assembly 2, in which the transformer assembly 1 is movably connected. Two limiting plates 3 are connected inside the sealing assembly 2. A connecting plate 103 is engaged with the limiting plates 3 to restrict the position of the transformer assembly 1. A protective assembly 5 is connected to the side of the limiting plates 3 that is far apart from each other to protect the transformer assembly 1 inside the sealing assembly 2.

[0037] In order to ensure that the limiting plate 3 can quickly limit the position of the transformer assembly 1 during use, and in the scheme, the cross-sectional structure of the limiting plate 3 is arranged as a "few" character, and the recessed positions of the limiting plate 3 are in a state of being opposite to each other, when the transformer assembly 1 is connected with the sealing assembly 2, the connecting plate 103 is slid into the groove of the limiting plate 3, and the connecting plate 103 can be clamped by the limiting plate 3, so that the position of the transformer assembly 1 is fixed, in order to ensure that the transformer assembly 1 can work normally in the sealing assembly 2 and will not damage the sealing assembly 2, the limiting plate 3 is arranged in the middle region of the sealing assembly 2, after the transformer assembly 1 is connected with the limiting plate 3, the transformer assembly 1 will not contact the sealing assembly 2.

[0038] And after the position of the transformer assembly 1 is clamped with the limiting plate 3, the conductive pin 1031 is in communication with the limiting plate 3, and the limiting plate 3 is in electrical communication with the outside of the sealing assembly 2.

[0039] In order to ensure the stability of the transformer assembly 1 during use, the protection assembly 5 specifically comprises an elastic bag 501, one end of the elastic bag 501 away from the limiting plate 3 is connected with the sealing assembly 2, a protection cavity 502 is formed in the elastic bag 501, and a plurality of folding plates 503 are connected in the protection cavity 502, the folding plates 503 are connected at opposite ends of the protection cavity 502, when the elastic bag 501 is extruded and shrinks, the space in the protection cavity 502 is reduced, and the folding plates 503 are folded.

[0040] It should be noted that in the present application, in order to ensure that the transformer assembly 1 can be stably supported during use, the two ends of the elastic bag 501 distributed along the width direction are made of hard material, and the two hard materials are made of elastic material.

[0041] Further, in order to effectively protect the transformer assembly 1, the sealing assembly 2 comprises a sealing shell 201, the sealing shell 201 can cover the transformer assembly 1, a communication end 202 is connected on the sealing shell 201, the limiting plate 3 is in electrical connection with the communication end 202, that is, during use, by being connected with the communication end 202, the conductive pin 1031 can be connected, so that the transformer assembly 1 can stably work in the sealing shell 201, a mounting cavity 2011 is formed in the sealing shell 201, one end of the mounting cavity 2011 penetrates through the sealing shell 201, the transformer assembly 1, the limiting plate 3 and the protection assembly 5 are located in the mounting cavity 2011, after the transformer assembly 1 is connected with the limiting plate 3, the transformer assembly 1 is located in the mounting cavity 2011 as a whole, a sealing plate 203 for sealing the opening position of the mounting cavity 2011 is connected on the sealing shell 201, so that the mounting cavity 2011 is a relatively sealed space.

[0042] In the process of using the device, the closing plate 203 is first opened, so that the installation cavity 2011 forms an open cavity, and then the transformer assembly 1 is connected with the limiting plate 3 and moves the transformer assembly 1, so that the transformer assembly 1 is completely located in the installation cavity 2011, and then the installation cavity 2011 is closed by the closing plate 203, so that the transformer assembly 1 is in a relatively closed space, and the circuit is connected with the communication end 202, so that the transformer assembly 1 can work stably.

[0043] It should be noted that in the process of using the safety sealing device, the conductive pin 1031 on the connecting plate 103 is in communication with the communication end 202 through the limiting plate 3.

[0044] In order to ensure the stability of the transformer assembly 1 in the installation cavity 2011, the transformer assembly 1 will not be damaged due to vibration or position movement, further, the limiting plate 3 and the protection assembly 5 are connected and provided with a buffer assembly 4 for limiting the position of the limiting plate 3, the buffer assembly 4 includes a buffer rod 401 and two buffer springs 402, the buffer rod 401 and the two ends of the two buffer springs 402 are respectively connected with the limiting plate 3 and the elastic bag 501, after the transformer assembly 1 is connected with the limiting plate 3, and in the case of external interference, the transformer assembly 1 shakes in the installation cavity 2011, and the limiting plate 3 synchronously shakes, at this time, if the shaking amplitude of the transformer assembly 1 is not limited, the service life of the transformer assembly 1 will be greatly affected, and in severe cases, short circuit may occur, at this time, the buffer rod 401 and the buffer spring 402 are compressed during the shaking process of the transformer assembly 1 and the limiting plate 3, so as to weaken the movement amplitude of the limiting plate 3 and ensure the stability of the transformer assembly 1.

[0045] When the amplitude of the transformer assembly 1 in the installation cavity 2011 is too large, at this time, the effective buffering of the transformer assembly 1 cannot be satisfied only by the action of the buffer rod 401 and the buffer spring 402, that is, when the transformer assembly 1 still has a moving tendency after one side of the buffer rod 401 and the buffer spring 402 is compressed to the maximum and the other side is stretched to the maximum, the compression of the buffer assembly 4 is used to exert force on the protection assembly 5, and the force at this time is greater than the force of the folding plate 503 and the elastic bag 501, so as to make the elastic bag 501 compressed and the folding plate 503 folded, so as to realize the absorption of the force on the buffer assembly 4, so as to realize the purpose of weakening the shaking amplitude of the transformer assembly 1.

[0046] Further, in order to ensure that the protection assembly 5 can identify the use state of the sealing assembly 2, and then the through hole is provided in the buffer rod 401, the installation cavity 2011 is communicated with the protection cavity 502 through the through hole, and the gas flow between the installation cavity 2011 and the protection cavity 502 is realized through the through hole. In the process of using the safety sealing structure, the gas pressure value between the installation cavity 2011 and the protection cavity 502 is ensured to be constant through the through hole.

[0047] When the transformer assembly 1 and the sealing assembly 2 are in normal working state, the pressure value between the installation cavity 2011 and the protection cavity 502 is the same at this time, and the folding plate 503 is partially folded at this time, and the elastic bag 501 is partially compressed.

[0048] When the temperature of the transformer assembly 1 continues to rise as the use time increases, the temperature in the installation cavity 2011 will rise, which will cause the gas in the installation cavity 2011 to expand and enter the protection cavity 502 through the through hole, so that the gas in the protection cavity 502 expands synchronously. However, since the temperature in the installation cavity 2011 is always higher than the temperature in the protection cavity 502, the expansion rate of the gas in the elastic bag 501 will be less than the expansion rate of the gas in the installation cavity 2011, that is, the installation cavity 2011 further compresses the elastic bag 501, and at this time, since the limiting plate 3 is connected with the transformer assembly 1 and the position does not change, the buffer assembly 4 will be elongated.

[0049] When the transformer assembly 1 is in normal working state, but the sealing state of the sealing assembly 2 leaks, the gas in the installation cavity 2011 will be discharged through the leakage point at this time, and at the same time, since the gas in the installation cavity 2011 is discharged, the gas in the protection cavity 502 quickly supplements the gas in the installation cavity 2011, which causes the gas in the protection cavity 502 to be quickly discharged, and then under the action of the folding plate 503, the elastic bag 501 will be quickly expanded.

[0050] Further, in order to ensure that the folding plate 503 can effectively support the protection cavity 502 and can reset the elastic bag 501, a torsional spring is connected at the folding position of the folding plate 503.

[0051] Further, the installation cavity 2011 and the elastic bag 501 are filled with inert gas, which ensures that the transformer assembly 1 can be normally used in the installation cavity 2011, and arc breakdown does not occur, and when the gas flows between the installation cavity 2011 and the elastic bag 501, the use state of the electronic transformer and the safety sealing structure can be identified in time, and the inert gas is preferably helium.

[0052] In order to identify the use state of the safety sealing structure, a display terminal is arranged on the sealing shell 201, which can display the stress condition and the extension length of the buffer assembly 4 in the installation cavity 2011, and intuitively judge the use condition of the transformer assembly 1 and the sealing assembly 2.

[0053] In use, first, the closing plate 203 is taken out, so that the installation cavity 2011 is opened, the transformer assembly 1 is connected with the limiting plate 3, the transformer assembly 1 is completely located in the installation cavity 2011, then the closing plate 203 is closed, and the inert gas is injected, and then the circuit to be connected is connected with the communication end 202, so that the circuit passes through the sealing assembly 2 and then passes through the transformer assembly 1, and the safety of the transformer assembly 1 in the use process is ensured.

[0054] When the device is in a normal working state, the inert gas in the installation cavity 2011 and the protection cavity 502 weakens the arc that may occur on the transformer assembly 1, and the buffer assembly 4 and the protection assembly 5 protect the state of the transformer assembly 1.

[0055] When the sealing shell 201 is impacted by the outside, the transformer assembly 1 is shaken in the installation cavity 2011, the limiting plate 3 is moved by the transformer assembly 1, the buffer rod 401 and the buffer spring 402 are elastically deformed, the elastic potential of the transformer assembly 1 is reduced, the vibration time and amplitude of the transformer assembly 1 are inhibited, and the safety of the transformer assembly 1 is ensured.

[0056] When the amplitude of the transformer assembly 1 in the installation cavity 2011 is too large, the effective buffering of the transformer assembly 1 cannot be met only by the buffer rod 401 and the buffer spring 402, that is, when the transformer assembly 1 still has a moving trend after one side of the buffer rod 401 and the buffer spring 402 is compressed to the maximum and the other side is elongated to the maximum, the protection assembly 5 is pressed by the compression of the buffer assembly 4, and the force at this time is greater than the force of the elastic bag 501 and the folding plate 503, the elastic bag 501 is compressed, the folding plate 503 is contracted under the action of the torsion spring, and since the installation cavity 2011 and the protection cavity 502 are in a relatively sealed chamber, the gas in the protection cavity 502 enters the installation cavity 2011 through the through hole after the elastic bag 501 is compressed, the gas concentration in the installation cavity 2011 is increased, the vibration of the transformer assembly 1 is inhibited, and the safe use of the transformer assembly 1 in the installation cavity 2011 is ensured.

[0057] At the same time, the buffer assembly 4 and the protection assembly 5 are used to protect the transformer assembly 1 and identify the use state of the safety sealing structure.

[0058] When the transformer assembly 1 and the sealing assembly 2 are in a normal working state, the pressure values between the installation cavity 2011 and the protection cavity 502 are the same, and in order to ensure that the elastic bag 501 and the gas in the installation cavity 2011 have the same pressure value, the folded plate 503 is partially folded, the elastic bag 501 is partially compressed, and the protection assembly 5 still has a protection effect on the transformer assembly 1.

[0059] When the transformer assembly 1 generates more and more heat as the use time increases, the temperature also increases correspondingly, the inert gas in the installation cavity 2011 is heated, the gas in the installation cavity 2011 expands and enters the protection cavity 502 through the through hole, the gas in the protection cavity 502 expands synchronously, but because the temperature in the installation cavity 2011 is always higher than the temperature in the protection cavity 502, that is, the expansion rate of the gas in the elastic bag 501 is less than the expansion rate of the gas in the installation cavity 2011, correspondingly, the gas pressure in the installation cavity 2011 is greater than the gas pressure in the protection cavity 502, that is, the gas in the installation cavity 2011 further compresses the elastic bag 501, and drives the length of the buffer rod 401 and the buffer spring 402 on both sides to elongate, the state of the buffer rod 401 and the buffer spring 402 can be identified and displayed, and it should be noted that when the transformer assembly 1 is in a normal working state, the temperature in the installation cavity 2011 and the protection cavity 502 tends to be stable after the transformer assembly 1 works, at this time, the buffer assembly 4 no longer changes obviously.

[0060] In the process of use, when the buffer rod 401 and the buffer spring 402 are excessively elongated, that is, the buffer rod 401 and the buffer spring 402 are close to the limit of elongation, at this time, it means that the use state of the transformer assembly 1 fails, and the user needs to be prompted to detect the transformer assembly 1.

[0061] When the transformer assembly 1 is always in normal working state, when the sealing state of the sealing assembly 2 appears leakage, the gas in the installation cavity 2011 will be discharged through the leakage point, and since the installation cavity 2011 is in communication with the protection cavity 502 through the through hole, when the gas in the installation cavity 2011 is discharged, the gas in the protection cavity 502 is quickly supplemented to the gas in the installation cavity 2011, so that the gas pressure in the protection cavity 502 is quickly reduced, and since the gas pressure in the installation cavity 2011 is also reduced, the pressure of the elastic bag 501 and the folding plate 503 is reduced, under the action of the torsion spring in the folding plate 503, the length of the folding plate 503 is elongated, and then the elastic bag 501 is quickly expanded, and the buffer assembly 4 on both sides is synchronously compressed, at this time, the user is prompted to detect and identify the sealing assembly 2, so as to ensure that the electronic transformer and the safety sealing structure are always in normal working state.
