In glass furnaces with higher output, since a single electrode cannot meet the current demand, multiple electrodes are often connected in parallel to one output end of the power supply. When used in parallel, due to the uneven density of the glass liquid in the glass furnace, the current distribution on multiple electrodes connected to the same power output end may be uneven.

[0034] In order to solve the problem of uneven current distribution of multiple electrodes connected in parallel to the output end of a power supply in a glass furnace with high output, the present application provides a power supply device for a glass furnace, wherein a ballast is connected between the power supply and the multiple electrodes to balance the current between the multiple electrodes. For details, please refer to Figure 1 , Figure 1 It is a structural schematic diagram of an embodiment of a glass kiln of the present application.
[0035] The power supply device 1 provided by the embodiments of the present application includes a power source 11, at least two electrodes 12, and a current regulator 13.
[0036] Among them, the current regulator 13 has an input end and two output ends. The output end of the power source 11 is connected to the input end of the current regulator 13. The at least two electrodes 12 include a first electrode 121 and a second electrode 122. The first end of the first electrode 121 and the first end of the second electrode 122 are respectively connected to the output ends of the current regulator 13. The second end of the first electrode 121 and the second end of the second electrode 122 are inserted into the glass liquid of the kiln furnace 2.
[0037] Furthermore, during the process of the power source 11 supplying power to the first electrode 121 and the second electrode 122 through the current regulator 13, the current regulator 13 is used to adjust the current of the first electrode 121 and the current of the second electrode 122 so that the current of the first electrode 121 is equal to the current of the second electrode 122. To ensure that in the glass liquid with different densities in the kiln furnace 2, the current of the first electrode 121 is equal to the current of the second electrode 122, the service lives of the first electrode 121 and the second electrode 122 are prolonged, the influence of the density of the contacted glass liquid on the current in the first electrode 121 and the second electrode 122 is avoided, the controllability of the current in the first electrode 121 and the second electrode 122 is improved, the uniformity of heating the glass liquid by the first electrode 121 and the second electrode 122 is ensured, and the practicability and reliability of the power supply device 1 are improved.
[0038] Optionally, please refer to Figure 2 , Figure 2 which is a schematic structural diagram of an embodiment of the current regulator of the present application. The current regulator 13 includes an induction body, a first winding S1, a second winding S2, a third winding S3, and a fourth winding S4.
[0039] Among them, the induction body has a first induction column 131, a second induction column 132, a first connecting piece 133, and a second connecting piece 134. The first end of the first induction column 131 is connected to the first end of the second induction column 132 through the first connecting piece 133. The second end of the first induction column 131 is connected to the second end of the second induction column 132 through the second connecting piece 134. That is to say, the cross-sectional shape of the induction body is a square frame shape. Among them, the first induction column 131, the second induction column 132, the first connecting piece 133, and the second connecting piece 134 can be silicon steel sheets.
[0040] The first winding S1, the second winding S2, the third winding S3, and the fourth winding S4 are respectively wound around the induction body. Among them, the first winding S1 and the third winding S3 are wound around the first induction column 131 at intervals along the extending direction of the first induction column 131, and the second winding S2 and the fourth winding S4 are wound around the second induction column 132 at intervals along the extending direction of the second induction column 132.
[0041] The power source 11 supplies power to the first electrode 121 through the first winding S1 and the fourth winding S4, and supplies power to the second electrode 122 through the second winding S2 and the third winding S3. The direction of the magnetic field generated by the current in the first winding S1 is the same as the direction of the magnetic field generated by the current in the second winding S2, the direction of the magnetic field generated by the current in the first winding S1 is opposite to the direction of the magnetic field generated by the current in the third winding S3, and the direction of the magnetic field generated by the current in the second winding S2 is opposite to the direction of the magnetic field generated in the fourth winding S4. Specifically, the first winding S1 is connected in series with the fourth winding S4, and the second winding S2 is connected in series with the third winding S3, wherein an end of the first winding S1 close to the second connecting member 134 is connected to an end of the fourth winding S4 close to the second connecting member 134, an end of the second winding S2 close to the second connecting member 134 is connected to an end of the third winding S3 close to the second connecting member 134, an end of the third winding S3 close to the first connecting member 133 is connected to the second electrode 122, and an end of the fourth winding S4 close to the first connecting member 133 is connected to the first electrode 121.
[0042] Furthermore, in the process that the power supply 11 supplies power to the first electrode 121 through the first winding S1 and the fourth winding S4, and supplies power to the second electrode 122 through the second winding S2 and the third winding S3, the magnetic field generated by the current in the first winding S1 on the first sensing column 131 and the magnetic field generated by the current in the third winding S3 will affect each other, and the magnetic field generated by the current in the second winding S2 on the second sensing column 132 and the magnetic field generated by the current in the fourth winding S4 will affect each other. If the current of the first electrode 121 and the current of the second electrode 122 are equal at this time, the magnetic field generated by the current in the first winding S1 and the magnetic field generated by the current in the third winding S3 are equal in magnitude and opposite in direction, and cancel each other out, and the magnetic field generated by the current in the second winding S2 and the magnetic field generated by the current in the fourth winding S4 are equal in magnitude and opposite in direction, and cancel each other out.
[0043] When the current of the first electrode 121 and the current of the second electrode 122 are not equal, the magnetic field generated by the current in the first winding S1 and the magnetic field generated by the current in the third winding S3 are opposite in direction and unequal in magnitude, and cannot be completely offset; and the magnetic field generated by the current in the second winding S2 and the magnetic field generated by the current in the fourth winding S4 are opposite in direction and unequal in magnitude, and cannot be completely offset. At this time, the remaining magnetic field on the first induction column 131 and the second induction column 132 will form a magnetic field loop through the first connecting member 133 and the second connecting member 134, and generate an induced current on the winding that generates a larger magnetic field to hinder the increased current, reduce the gap between the current of the first electrode 121 and the current of the second electrode 122, until the current of the first electrode 121 is equal to the current of the second electrode 122.
[0044] Among them, Figure 2As shown, port 1 is one end of the first winding S1 close to the first connector 133, port 2 is one end of the first winding S1 close to the second connector 134, port 3 is one end of the fourth winding S4 close to the second connector 134, port 4 is one end of the fourth winding S4 close to the first connector 133, port 5 is one end of the second winding S2 close to the first connector 133, port 6 is one end of the second winding S2 close to the second connector 134, port 7 is one end of the third winding S3 close to the second connector 134, and port 8 is one end of the third winding S3 close to the first connector 133.
[0045] That is, when the power source 11 supplies power to the first electrode 121 and the second electrode 122 via the ballast 13, the current output by the power source 11 first enters the first winding S1 via the port 1 of the first winding S1, and enters the fourth winding S4 via the port 2 of the first winding S1 and the port 3 of the fourth winding S4, and then enters the first electrode 121 via the port 4 of the fourth winding S4. At the same time, the current output by the power source 11 first enters the second winding S2 via the port 5 of the second winding S2, and enters the third winding S3 via the port 6 of the second winding S2 and the port 7 of the third winding S3, and then enters the second electrode 122 via the port 8 of the third winding S3.
[0046] The first winding S1, the second winding S2, the third winding S3 and the fourth winding S4 may be wound in the same direction on the induction body. The end of the first winding S1 close to the second connector 134 and the end of the fourth winding S4 close to the second connector 134 are opposite ends with opposite polarities; and the end of the second winding S2 close to the second connector 134 and the end of the third winding S3 close to the second connector 134 are opposite ends with opposite polarities.
[0047] Furthermore, the first winding S1 and the second winding S2 are connected in parallel, and one end of the first winding S1 close to the first connecting piece 133 is connected to one end of the second winding S2 close to the first connecting piece, and one end of the first winding S1 close to the first connecting piece 133 and one end of the second winding S2 close to the first connecting piece 133 are the same ends with the same polarity.
[0048] In the process of the power supply 11 supplying power to the first electrode 121 and the second electrode 122 through the ballast 13, the current in the first winding S1 will induce a first magnetic field, the current in the second winding S2 will induce a second magnetic field, the current in the third winding S3 will induce a third magnetic field, and the current in the fourth winding S4 will induce a fourth magnetic field. Since the first winding S1 and the fourth winding S4 are connected in series, and the end of the first winding S1 close to the second connector 134 and the end of the fourth winding S4 close to the second connector 134 are opposite ends, the current in the first winding S1 is equal to the current in the fourth winding S4, then, the magnitude of the first magnetic field is equal to the magnitude of the fourth magnetic field, and the direction of the first magnetic field is opposite to the direction of the fourth magnetic field. Similarly, the magnitude of the second magnetic field is equal to the magnitude of the third magnetic field, and the direction of the second magnetic field is opposite to the direction of the third magnetic field.
[0049] Since the first winding S1 and the second winding S2 are connected in parallel, the end of the first winding S1 close to the first connector 133 and the end of the second winding S2 close to the first connector 133 are the same end, so the direction of the first magnetic field is equal to the direction of the second magnetic field. It can be obtained that on the first sensing column 131, the direction of the first magnetic field is opposite to the direction of the third magnetic field; on the second sensing column 131, the direction of the second magnetic field is opposite to the direction of the fourth magnetic field.
[0050] Thus, the direction of the magnetic field generated by the current in the first winding S1 is the same as the direction of the magnetic field generated by the current in the second winding S2, the direction of the magnetic field generated by the current in the first winding S1 is opposite to the direction of the magnetic field generated by the current in the third winding S3, and the direction of the magnetic field generated by the current in the second winding S2 is opposite to the direction of the magnetic field generated in the fourth winding S4. The magnetic fields generated by the currents in each winding affect each other, so that the current of the first electrode 121 and the current of the second electrode 122 remain equal.
[0051] In one embodiment, if the current in the first winding S1 is equal to the current in the second winding S2, that is, the current of the first electrode 121 is equal to the current of the second electrode 122, then the current in the first winding S1, the current in the second winding S2, the current in the third winding S3, and the current in the fourth winding S4 are equal to each other. That is, on the first sensing column 131, the magnitude of the magnetic field generated by the current in the first winding S1 is equal to the magnitude of the magnetic field generated by the current in the third winding S3, and the direction of the magnetic field generated by the current in the first winding S1 is opposite to the direction of the magnetic field generated by the current in the third winding S3, and the magnetic field generated by the current in the first winding S1 and the magnetic field generated by the current in the third winding S3 cancel each other out. On the second sensing column 132, the magnitude of the magnetic field generated by the current in the second winding S2 is equal to the magnitude of the magnetic field generated by the current in the fourth winding S4, and the direction of the magnetic field generated by the current in the second winding S2 is opposite to the direction of the magnetic field generated by the current in the fourth winding S4, and the magnetic field generated by the current in the second winding S2 and the magnetic field generated by the current in the fourth winding S4 cancel each other out. Furthermore, the magnetic field generated by the current in each winding will not generate an induced current in other windings to affect the current of other windings, and the current of the first electrode 121 and the current of the second electrode 122 remain equal.
[0052] That is, when the current of the first electrode 121 is equal to the current of the second electrode 122, the magnetic fields generated by the currents in the first winding S1, the second winding S2, the third winding S3 and the fourth winding S4 of the sensing body cancel each other out, there is no magnetic field loop in the sensing body, and the current of the first electrode 121 and the current of the second electrode 122 remain equal.
[0053] In another embodiment, if the current in the first winding S1 is greater than the current in the second winding S2, that is, the current in the first electrode 121 is greater than the current in the second electrode 122, then on the first sensing column 131, the magnitude of the magnetic field generated by the current in the first winding S1 is greater than the magnitude of the magnetic field generated by the current in the third winding S3, and a magnetic field exists on the first sensing column 131, and the direction of the magnetic field is the same as the direction of the magnetic field generated by the current in the first winding S1. On the second sensing column 132, the magnitude of the magnetic field generated by the current in the second winding S2 is less than the magnitude of the magnetic field generated by the current in the fourth winding S4, and a magnetic field exists on the second sensing column 132, and the direction of the magnetic field is the same as the direction of the magnetic field generated by the current in the fourth winding S4.
[0054] Among them, Figure 2From the perspective shown, since the direction of the magnetic field generated by the current in the first winding S1 is opposite to the direction of the magnetic field generated by the current in the fourth winding S4, if the direction of the magnetic field generated by the current in the first winding S1 is downward, the direction of the magnetic field generated by the current in the fourth winding S4 is upward. Since the first end of the first sensing column 131 is connected to the first end of the second sensing column 132 through the first connecting member 133, and the second end of the first sensing column 131 is connected to the second end of the second sensing column 132 through the second connecting member 134, the magnetic field on the first sensing column 131 will enter the second sensing column 132 through the first connecting member 133, and the magnetic field on the second sensing column 132 will enter the first sensing column 131 through the second connecting member 134. The magnetic fields on the two sensing columns flow mutually, forming a magnetic field loop in the sensing body, and the direction of the magnetic field loop is counterclockwise.
[0055] Furthermore, the magnetic field loop will generate induced current in the first winding S1 and the fourth winding S4. Specifically, the magnetic field loop will generate a first induced current in the first winding S1. At the same time, the magnetic field loop will generate a second induced current in the fourth winding S4. According to Lenz's law, at this time, the direction of the first induced current is opposite to the original current direction in the first winding S1, and the direction of the second induced current is opposite to the original current direction in the fourth winding S4, so as to reduce the current size in the first winding S1 and the current size in the fourth winding S4.
[0056] Until the current in the first winding S1 is equal to the current in the second winding S2 again, that is, the current in the first electrode 121 is equal to the current in the second electrode 122, at this time there is no magnetic field loop on the induction body, and no induced current is generated in the first winding S1 and the fourth winding S4.
[0057] In summary, when the current of the first electrode 121 is larger than the current of the second electrode 122, the leveler 13 is used to reduce the current of the first electrode 121 so that the current of the first electrode 121 is equal to the current of the second electrode 122, thereby avoiding uneven current distribution on the first electrode 121 and the second electrode 122, and uneven heating of the glass liquid by the first electrode 121 and the second electrode 122. The leveler 13 is able to adjust the current on the first electrode 121 and the second electrode 122, thereby improving the practicality and reliability of the leveler 13, improving the operating efficiency of the power supply device 1, and enhancing the user experience of the power supply device 1.
[0058] In other embodiments, if the current in the first winding S1 is smaller than the current in the second winding S2, that is, the current in the first electrode 121 is smaller than the current in the second electrode 122, then on the first sensing column 131, the magnitude of the magnetic field generated by the current in the first winding S1 is smaller than the magnitude of the magnetic field generated by the current in the third winding S3, a magnetic field exists on the first sensing column 131, and the direction of the magnetic field is the same as the direction of the magnetic field generated by the current in the third winding S3. On the second sensing column 132, the magnitude of the magnetic field generated by the current in the second winding S2 is greater than the magnitude of the magnetic field generated by the current in the fourth winding S4, a magnetic field exists on the second sensing column 132, and the direction of the magnetic field is the same as the direction of the magnetic field generated by the current in the second winding S2.
[0059] Among them, Figure 2 From the perspective shown, since the magnetic field generated by the current in the second winding S2 is in opposite directions to the magnetic field generated by the current in the third winding S3, if the magnetic field generated by the current in the second winding S2 is in a downward direction, the magnetic field generated by the current in the third winding S3 is in an upward direction. Since the first end of the first sensing column 131 is connected to the first end of the second sensing column 132 through the first connecting member 133, and the second end of the first sensing column 131 is connected to the second end of the second sensing column 132 through the second connecting member 134, the magnetic field on the first sensing column 131 and the magnetic field on the second sensing column 132 flow through each other, forming a magnetic field loop in the sensing body, and the direction of the magnetic field loop is clockwise.
[0060] Furthermore, the magnetic field loop will generate induced current in the second winding S2 and the third winding S3. Specifically, the magnetic field loop will generate a first induced current in the second winding S2. At the same time, the magnetic field loop will generate a second induced current in the third winding S3. According to Lenz's law, at this time, the direction of the first induced current is opposite to the original current direction in the second winding S2, and the direction of the second induced current is opposite to the original current direction in the third winding S3, so as to reduce the current size in the second winding S2 and the current size in the third winding S3.
[0061] Until the current in the second winding S2 is equal to the current in the first winding S1 again, that is, the current in the first electrode 121 is equal to the current in the second electrode 122, at this time there is no magnetic field loop on the induction body, and no induced current is generated in the second winding S2 and the third winding S3.
[0062] In summary, when the current of the first electrode 121 is smaller than the current of the second electrode 122, the leveler 13 is used to reduce the current of the second electrode 122 so that the current of the first electrode 121 is equal to the current of the second electrode 122, thereby avoiding uneven current distribution on the first electrode 121 and the second electrode 122, and uneven heating of the glass liquid by the first electrode 121 and the second electrode 122. The leveler 13 is able to adjust the current on the first electrode 121 and the second electrode 122, thereby improving the practicality and reliability of the leveler 13, improving the operating efficiency of the power supply device 1, and enhancing the user experience of the power supply device 1.
[0063] Therefore, according to the analysis of the above situation, in the process of the power supply 11 supplying power to the first electrode 121 and the second electrode 122 through the leveler 13, the current in the first winding S1, the current in the second winding S2, the current in the third winding S3 and the current in the fourth winding S4 will generate a magnetic field, and when the current of the first electrode 121 and the current of the second electrode 122 are not equal, a magnetic field loop will be generated in the leveler 13 to suppress the increase of the current, adjust the current of the first electrode 121 and the current of the second electrode 122, and ensure that the current of the first electrode 121 and the current of the second electrode 122 are equal. Reduce the loss of the first electrode 121 and the second electrode 122, extend the life of the first electrode 121 and the second electrode 122, improve the uniformity of heating the glass liquid in the kiln 2, improve the practicality of the power supply device 1, and improve the quality of the manufactured glass.
[0064] In one embodiment, other numbers of electrodes 12 may be connected to the ballast 13, such as three electrodes in parallel, four electrodes in parallel, etc., which may be set according to user needs; further, when other numbers of electrodes are connected in parallel to the ballast 13, the number of windings and the number of induction columns in the ballast 13 may be increased based on the number of connected electrodes, and the present application does not impose any restrictions on this.
[0065] The present application also provides a glass furnace A, such as Figure 1 The method comprises a power supply device 1 and a kiln 2, wherein at least two electrodes 12 of the power supply device 1 are inserted into the glass liquid in the kiln 2 to heat the glass liquid.
[0066] Optionally, see Figure 1 The power supply 11 may be a three-phase power supply, the power supply device 1 may include a first group of rectifiers 13, a second group of rectifiers 13 and a third group of rectifiers 13, and the at least two electrodes 12 further include a third electrode 123, a fourth electrode 124, a fifth electrode 125 and a sixth electrode 126.
[0067] Among them, the first electrode 121 and the second electrode 122 are connected to the first output end of the power supply 11 through the first group of ballasts 13, the third electrode 123 and the fourth electrode 124 are connected to the second output end of the power supply 11 through the second group of ballasts 13, and the fifth electrode 125 and the sixth electrode 126 are connected to the third output end of the power supply 11 through the third group of ballasts 13.
[0068] Furthermore, one end of the first electrode 121, the second electrode 122, the third electrode 123, the fourth electrode 124, the fifth electrode 125 and the sixth electrode 126 are inserted into the glass liquid in the kiln 2, and the power supply 11 supplies power to the first electrode 121, the second electrode 122, the third electrode 123, the fourth electrode 124, the fifth electrode 125 and the sixth electrode 126 through the first group of rectifiers 13, the second group of rectifiers 13 and the third group of rectifiers 13 to heat the glass liquid in the kiln 2.
[0069] Wherein, when the current on the first electrode 121 and the current on the second electrode 122 are not equal, the first group of levelers 13 is used to adjust the current on the first electrode 121 and the current on the second electrode 122 so that the current on the first electrode 121 and the current on the second electrode 122 are equal. When the current on the third electrode 123 and the current on the fourth electrode 124 are not equal, the second group of levelers 13 is used to adjust the current on the third electrode 123 and the current on the fourth electrode 124 so that the current on the third electrode 123 and the current on the fourth electrode 124 are equal. When the current on the fifth electrode 125 and the current on the sixth electrode 126 are not equal, the third group of levelers 13 is used to adjust the current on the fifth electrode 125 and the current on the sixth electrode 126 so that the current on the fifth electrode 125 and the current on the sixth electrode 126 are equal.
[0070] The currents of the electrodes connected to each other are adjusted by the first group of levelers 13, the second group of levelers 13 and the third group of levelers 13, thereby ensuring the uniformity of the currents between the electrodes, ensuring the uniformity of the heating of the glass liquid in the kiln 2 by the multiple electrodes 12, improving the practicality of the levelers 13, and improving the practicality and reliability of the power supply equipment 1.
[0071] Optionally, the second end of the first electrode 121, the second end of the second electrode 122, the second end of the third electrode 123, the second end of the fourth electrode 124, the second end of the fifth electrode 125 and the second end of the sixth electrode 126 are arranged at intervals in the glass liquid of the kiln 2, and the distance between the second end of any electrode 12 and the second end of the adjacent electrode 12 is equal, thereby avoiding the situation where part of the glass liquid in the kiln 2 is heated to too high a temperature due to the densely arranged electrodes 12, and part of the glass liquid is heated to insufficient temperature due to the small number of electrodes 12, further ensuring the uniformity of heating the glass liquid in the kiln 2 by multiple electrodes 12, thereby improving the quality of the manufactured glass.
[0072] In summary, in the power supply equipment 1 provided in the embodiment of the present application, the stabilizer 13 is used to adjust the current of the electrodes 12 connected in parallel to the same output end of the power supply 11, so that the current of each electrode 12 is equal, so as to reduce the loss of the electrode 12, extend the life of the electrode 12, improve the heating uniformity of the glass liquid in the kiln 2, improve the practicality of the stabilizer 13, improve the practicality of the power supply equipment 1, improve the operating efficiency of the glass kiln A, and improve the quality of the manufactured glass.
