Description

Technical Field

[0001] The utility model relates to the field of bushing heating, in particular to a connection structure of the secondary circuit of a transformer for heating a platinum bushing. Background Art

[0002] The glass fiber bushing heating process uses a water-cooled transformer. The main function of the water-cooled transformer is to use the electric energy output by itself as the main heat source for the bushing to rise in temperature (constant temperature), convert the electric energy into heat energy, and realize the production of glass fiber drawing by heating the bushing. The production of glass fiber requires the water-cooled transformer to change the high voltage and working current on the primary side into the low voltage and large current on the secondary side.

[0003] Patent No. ZL201621470729.6 discloses a centrifugal glass wool bushing flow heating device, which realizes the power supply operation of the bushing by arranging an energized circuit structure on one side of the bushing. Since the secondary circuit current is as high as more than 10,000 A, a strong magnetic field will be formed on one side of the bushing. Different-density induced currents will be generated in the bushing in the strong magnetic field (as shown in Figure 1 ), resulting in uneven heating of the bushing and affecting the temperature uniformity of bushing heating. It is necessary to improve it. Summary of the Invention

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A connection structure of the secondary circuit of a transformer for heating a platinum bushing includes a bushing load, and both ends of the bushing load are electrically connected to the high-voltage control part of the transformer; a first copper bar and a second copper bar are arranged between the bushing load and the high-voltage control part of the transformer. The first copper bar is in the shape of a rectangular ring with one end open and is arranged on the outer periphery of the bushing load. Both ends of the first copper bar are electrically connected to the high-voltage control part of the transformer; the second copper bar is arranged between both ends of the first copper bar. One end of the second copper bar is electrically connected to the high-voltage control part of the transformer, and the other end of the second copper bar is electrically connected to one end of the bushing load close to the transformer in the length direction. One end of the bushing load far from the transformer in the length direction is electrically connected to the middle of the first copper bar.

[0007] Furthermore, one side of the strong - electricity control part of the transformer is fixedly connected with a first mounting part. There are three first mounting parts, and the three first mounting parts are arranged at equal intervals along the width direction of the leakage - plate load. The strong - electricity control part of the transformer is electrically connected with the first mounting parts; a first clamping hole is arranged in the first mounting part; the three first mounting parts are respectively fixedly connected with both ends of a first copper bar and one end of a second copper bar through the first clamping holes.

[0008] Furthermore, a second mounting part is arranged in the middle of the first copper bar. A second clamping hole is arranged on the second mounting part, and the second mounting part is fixedly sleeved outside the middle of the first copper bar through the second clamping hole. The second mounting part is electrically connected with one end in the length direction of the leakage - plate load.

[0009] Furthermore, the leakage - plate load is a platinum plate. The leakage - plate load is in the shape of a rectangular plate.

[0010] Furthermore, a first connecting copper bar is arranged between the first load connection block and the second mounting part. The first load connection block is fixedly connected with the second mounting part through the first connecting copper bar; a second connecting copper bar is arranged between the second load connection block and the second copper bar.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are:

[0013] Through the design of arranging the first copper bar and the first copper bar being annularly arranged on the outer periphery of the leakage - plate load, when the leakage - plate load is heated, the current of the strong - electricity control part of the transformer simultaneously supplies power to both ends of the leakage - plate load through the first copper bar and the second copper bar. The first copper bars located on both sides in the width direction of the leakage - plate load are evenly arranged, so that the first copper bars form a uniform strong magnetic field on both sides of the leakage - plate load, thereby enabling the leakage - plate load to generate an induced current with uniform density in the strong magnetic field. This induced current can make the leakage - plate load heat evenly, ensuring the uniformity of the leakage - plate load heating and effectively improving the heating effect of the leakage - plate load.

[0019] As Figure 2 shown, this embodiment discloses a connection structure of the secondary circuit of a transformer for platinum orifice plate heating, including an orifice plate load 3, and both ends of the orifice plate load 3 are electrically connected to the strong electricity control part of the transformer 1;

[0020] The orifice plate load 3 is in the shape of a platinum rectangular plate. A first copper bar 10 and a second copper bar 4 are arranged between the orifice plate load 3 and the strong electricity control part of the transformer 1. The first copper bar 10 is in the shape of a rectangular ring with one end open and is arranged on the outer periphery of the orifice plate load 3. Both ends of the first copper bar 10 are electrically connected to the strong electricity control part of the transformer 1; the strong electricity control part of the transformer 1 is arranged on one side of the open end of the first copper bar 10. The second copper bar 4 is arranged between both ends of the first copper bar 10. One end of the second copper bar 4 is electrically connected to the strong electricity control part of the transformer 1, and the other end of the second copper bar 4 is electrically connected to one end of the orifice plate load 3 close to the length direction of the transformer 1. One end of the orifice plate load 3 far from the transformer 1 in the length direction is electrically connected to the middle part of the first copper bar 10.

[0021] One end in the length direction of the orifice plate load 3 is fixedly connected with a first load connection block 6, and the other end in the length direction of the orifice plate load 3 is fixedly connected with a second load connection block 7; both the first load connection block 6 and the second load connection block 7 are metal conductive blocks.

[0022] On one side of the strong - electricity control part of the transformer 1, there is a first mounting part 2 fixedly connected. There are three first mounting parts 2, and the three first mounting parts 2 are arranged at equal intervals along the width direction of the leakage - plate load 3. The strong - electricity control part of the transformer 1 is electrically connected to the first mounting part 2; a first clamping hole is arranged in the first mounting part 2; the three first mounting parts 2 are respectively fixedly connected to both ends of the first copper bar 10 and one end of the second copper bar 4 through the first clamping holes.

[0023] In the middle of the first copper bar 10, there is a second mounting part 5. The second mounting part 5 is provided with a second clamping hole and is fixedly sleeved outside the middle part of the first copper bar 10 through the second clamping hole. The second mounting part 5 is fixedly connected to the first load - connecting block 6 through the first connecting copper bar 9.

The first copper bars located on both sides of the width direction of the leakage - plate load are evenly arranged, so that a uniform strong magnetic field is formed by the first copper bars on both sides of the leakage - plate load, thereby enabling a uniformly - distributed induced current to be generated in the leakage - plate load in the strong magnetic field (as Figure 3 shown). This induced current can make the leakage - plate load heat evenly, ensuring the uniformity of the leakage - plate load heating, and thus effectively improving the heating effect of the leakage - plate load.
