Description

Technical Field

[0002] Zero-flux Hall-effect current sensors, also known as closed-loop Hall-effect current sensors, are based on the magnetically balanced Hall principle and closed-loop design. When the magnetic flux generated by the primary current IP is concentrated in the magnetic circuit through a high-quality magnetic core, a Hall element is fixed in the air gap to detect the magnetic flux. A multi-turn coil wound around the core outputs a reverse compensation current to offset the magnetic flux generated by the primary IP, maintaining the magnetic flux in the magnetic circuit at zero. Through special circuit processing, the sensor's output output accurately reflects the changes in the primary current.

[0003] When using existing zero-flux Hall current sensors, the outer shell is mostly cast in one piece or spliced ​​with front and back halves by bolts.

The magnetoelectric conversion element is fixed through the cooperation of the front and rear clamping plates, so that the position of the magnetoelectric conversion element in the top frame is stable, which increases the stability of the device when in use.

[0020] 2. The high-strength protection zero-flux current transformer housing has a connecting mechanism, so the staff only needs to insert the insert plate into the front and rear sides of the base. The interface of the card plate 1 is inserted into the front and rear sides of the base and fits into the inner and outer sides of the left and right ends of the card frame at the same time, completing the stabilization of the card frame connected to the base, increasing the stability of the top frame and the base after splicing.

At the same time, since the racks on the upper and lower sides are respectively driven and controlled by the transmission gear rollers on the upper and lower sides that mesh with each other, the staff only needs to drive the upper rotating rod to rotate to control the racks on the upper and lower sides to move synchronously inward or outward, ensuring the synchronization of the movement of the upper and lower racks.

[0044] Example 3

[0045] See Figure 1 、 Figure 7 、 Figure 8 and Figure 9 On the basis of Example 1 and Example 2, it is further obtained that the regulating mechanism 3 includes an adjusting component 31 and a positioning component 32, the adjusting component 31 is arranged on the left and right sides of the base 4, and the positioning component 32 is arranged on the left and right sides inside the base 4.

[0046] The adjustment component 31 includes a torsion plate 3101, which is arranged on the left and right sides of the base 4.

[0047] Furthermore: the staff only needs to twist the torsion plates 3102 on the left and right sides to control the racks 2202 on the left and right sides of the base 4 to move synchronously inward and outward, which makes it convenient for the staff to control the racks 2202 to complete the disassembly and assembly of the top frame 1101. At the same time, since the racks 2202 on the upper and lower sides are respectively driven and controlled by the transmission gear rollers 3203 that mesh with each other on the upper and lower sides, the staff only needs to drive the upper rotating rod 3202 to rotate to control the racks 2202 on the upper and lower sides to move synchronously inward or outward, ensuring the synchronization of the movement of the racks 2202 on the upper and lower sides. At the same time, the worm 3105 and the worm wheel 3201 cooperate in transmission, so that the rotating rod 3202 in the base 4 cannot rotate by itself to drive the rotating shaft 3104 to rotate, thereby increasing the stability of the top frame 1101 after installation.

[0048] During actual operation, when this device is used, when the magnetoelectric conversion element 5 needs to be replaced, the staff first twists the torsion plates 3102 on the left and right sides. The rotation of the torsion plates 3102 drives the rotating shaft 3104 to rotate through the torsion disk 3101. The rotation of the rotating shaft 3104 drives the worm gear 3201 to rotate through the worm 3105. The rotation of the worm gear 3201 drives the transmission gear roller 1 3203 to rotate through the rotating rod 1 3202. The rotation of the transmission gear roller 1 3203 drives the upper rack 2202 to move outward. At the same time, the rotation of the transmission gear roller 1 3203 drives the lower transmission gear roller 2 3204 to rotate in the opposite direction. The rotation of the transmission gear roller 2 3204 drives the lower rack 2202 to move outward. The racks 2202 on the upper and lower sides move outward, driving the card plate 2 201 to move outward. , the second card plate 2201 moves outward to release the connection with the card plate 1 2102 and the card frame 1102, and then the staff can move the top frame 1101 upward to complete the disassembly of the top frame 1101 and the base 4, and then the staff rotates the torsion rings 1202 on the left and right sides, and the rotation of the torsion rings 1202 on the left and right sides drives the screw tube 1203 to rotate, and the screw tube 1203 rotates on the inner circle of the fixed screw barrel 1201 to move outward, and the screw tube 1203 moves outward to release the connection between the torsion ring 1202 and the fixed screw barrel 1201, so that the torsion ring 1202 releases the positioning of the top frames 1101 on the front and rear sides, and then the staff can move the top frames 1101 on the front and rear sides outward to release the connection between the protruding rod 1104 and the sleeve block 1105 to complete the disassembly of the magnetoelectric conversion element 5;

[0049] After that, the staff will place the new magnetoelectric conversion element 5 in the top frame 1101, so that the sleeve 1105 is sleeved on the outer ring of the protruding rod 1104 on one side, and then the staff will splice the front and rear top frames 1101, so that the protruding rod 1104 on the other side is also clamped on the inner ring of the sleeve 1105. After that, the staff will control the torsion ring 1202 to insert the screw tube 1203 into the inner ring of the fixed screw barrel 1201 while keeping the front and rear top frames 1101 spliced ​​together, and the screw tube 1203 rotates on the inner ring of the fixed screw barrel 1201 to drive the torsion ring 1202 to move inward, and the torsion ring 1202 moves inward and sleeves on the outer rings of the front and rear fixed screw barrels 1201 to complete the splicing and fixation of the front and rear top frames 1101. After that, the staff will control the top frame 1101 to insert the card frame 1102 into the top of the base 4, so that the card frame 11 02 bottom is fitted with the bottom of the base 4, and then the staff inserts the inlay plate 2101 and the card plate 1 2102 into the front and rear sides of the base 4, so that the card plate 1 2102 is set on the inner and outer sides of the left and right ends of the card frame 1102 to complete the stabilization of the position of the card frame 1102, and then the staff twists the torsion plates 3102 on the left and right sides. It can be seen from the above that the rotation of the torsion plates 3102 drives the racks 2202 at the upper and lower ends on the left and right sides of the base 4 to move synchronously. At this time, the rotation of the torsion plates 3102 drives the multiple racks 2202 to move inward synchronously, and the multiple racks 2202 move inward synchronously to drive the card plate 2 2201 to move inward. The card plate 2 2201 moves inward through the card frame 1102 and the card plate 1 2102 and is connected to the card frame 1102 and the card plate 1 2102. At this time, the installation of the top frame 1101 is completed;

[0050] Finally, the staff starts the driving motors 1302 on the front and rear sides. The driving motors 1302 start and drive the driving gears 1304 to rotate through the rotating shaft 1303. The driving gears 1304 rotate through the transmission gears 1 1401 on the left and right sides and drive the transmission gears 2 1501 on the left and right sides to rotate. The transmission gears 2 1501 on the left and right sides rotate through the threaded rotating cylinder 1502 and drive the threaded rods 1503 on the left and right sides to move inward and outward synchronously. The movement of the splint 1504 drives the limit plate 1505 to move until the limit plates 1505 on the front and rear sides move inward and outward to push the magnetoelectric conversion element 5 to the middle position in the top frame 1101.
