Description

Technical Field

[0001] The present invention relates to the technical field of current transformers, and in particular to a winding device and a winding method for a primary coil of a current transformer. Background Art

[0002] After the secondary coil is wound on the microcrystalline iron core in the current transformer, a rectangular silk-wrapped tape primary coil is wound on the outer side of the microcrystalline iron core through a winding device.

[0003] Different current transformers have different sizes of microcrystalline cores, so the specifications of the rectangular primary coils at the winding point are also different. The existing winding devices are mostly used for winding current transformers of a single specification. At the same time, when winding, the width and thickness of the silk tape are different, and the width of the rectangular seat used for winding limit is fixed, and the silk tape cannot be limited. Therefore, during the winding process, the silk tape cannot be limited and guided, which causes the silk tape to deviate. At the same time, due to the high hardness of the silk tape, workers are required to perform hammering and adjustment during winding, otherwise the wound primary coil is uneven and has poor aesthetics.

[0018] A winding method for a winding device of a primary coil of a current transformer, the specific operation steps of the winding method are as follows:

[0019] Step 1: Install the rectangular seat on the mounting ring according to the specifications of the wound primary coil, and place the microcrystalline iron core wound with the secondary coil vertically on the core slot of the iron core seat, with the bottom of the microcrystalline iron core in contact with the bottom side of the core slot. The second threaded rod is driven to rotate by the third motor, and then the two limit plates connected by thread are driven to approach the microcrystalline iron core, and the microcrystalline iron core is clamped and fixed. The first threaded rod is driven to rotate by the second motor, and then the threaded core seat is driven to move up along the vertical slot. When moving up, the motor drives the rotating plate to rotate. At this time, the rotating plate rotates upward until the notch of the rectangular seat is in an open state. At this time, the core seat moves to the inside of the rectangular seat, and the rotating plate rotates to the initial position.

[0020] Step 2: Place the silk-wrapped tape between the first baffle and the second baffle. At this time, the first spring pulls the second baffle toward the first baffle to limit the silk-wrapped tape. At the same time, the second spring drives the lifting rod to move downward to press the second set of wheels on the silk-wrapped tape. At the same time, the third spring acts on the second inner wheel to drive the two translation wheel rods to move away from each other. At this time, the second set of wheels and the second inner wheel are respectively blocked by the first baffle and the second baffle to ensure that the combined length of the first inner wheel and the first set of wheels is the same as the combined length of the second set of wheels and the second inner wheel. The third mounting shaft is driven to rotate by the fifth motor, and then the silk-wrapped tape is transported by the rotating first inner wheel and the first set of wheels.

[0021] Step 3: The end of the silk-wrapped tape moves to the right-angle groove of the rectangular seat. At this time, the second pneumatic cylinder is in an extended state, and the piston rod of the second pneumatic cylinder blocks the end of the silk-wrapped tape. Then the second pneumatic cylinder contracts to drive the right-angle pressure block to move down, and the end of the silk-wrapped tape is clamped between the right-angle groove and the right-angle pressure block. The first motor works, the synchronous wheel and the synchronous belt drive, and the second mounting shaft and the rotating gear are rotated. The rotating gear drives the meshing gear ring to rotate clockwise, and the ring seat is located between the guide wheels and rotates clockwise. After the gear ring rotates 90°, the first pneumatic cylinder works to drive the right-angle seat to move until the horizontal section of the right-angle seat contacts the silk-wrapped tape on the top side of the rectangular seat, and the vertical section of the right-angle seat contacts the silk-wrapped tape on the side wall of the rectangular seat. The fourth motor works to drive the third threaded rod to rotate, and then drives the threaded wheel seat to move along the pressure groove, and the silk-wrapped tape on the top side of the rectangular seat is flattened by the pressure wheel. Then the first pneumatic cylinder contracts, and the rectangular seat continues to rotate, and each rotation angle is 90°, and it is flattened by the right-angle seat and the pressure wheel.

[0022] Step 4: After the winding is completed, the rotating plate is rotated again until the notch is in an open state, and at the same time, the limit plate is separated from the microcrystalline iron core, and the right-angle pressing block moves up in the right-angle groove and does not exceed the top side of the rectangular seat. At this time, the primary coil is removed from the rectangular seat and the microcrystalline iron core is removed from the core seat.

[0023] The beneficial effects of the present invention are as follows: the microcrystalline iron core is initially placed through the iron core groove of the iron core seat, and the microcrystalline iron core is limited and fixed through the limit plate, and the height of the microcrystalline iron core is adjusted through the lifting and moving iron core seat, thereby completing the fixation and loading and unloading of microcrystalline iron cores of different specifications, and at the same time, the mounting ring and the rectangular seat are connected by bolts, which is convenient for replacing the rectangular seat, and then cooperates to complete the winding work of the primary coil of the current transformer of different specifications;

[0024] Under the action of the first spring, the first baffle and the second baffle automatically contact the side wall of the silk tape, thereby limiting the position of silk tapes of different widths during the conveying process, and preventing the silk tapes from deviating in the horizontal direction during the winding process. At the same time, under the action of the second spring, the second set of wheels and the second inner wheel act on the top side of the silk tape, and cooperate with the first inner wheel and the first set of wheels to limit the position of the silk tape in the vertical direction.

[0025] During the winding process, the first pneumatic cylinder is used to move the right-angle seat, so that the horizontal section of the right-angle seat contacts the silk tape on the top side of the rectangular seat, and the vertical section of the right-angle seat contacts the silk tape on the side wall of the rectangular seat. The silk tape on the top side of the rectangular seat is flattened by the translational wheel seat and the pressure wheel, and automatic flattening is achieved to ensure that each layer of silk tape fits tightly and is wrinkle-free.
