[0002] The amorphous alloy transformer is a low-loss, high-efficiency power transformer that uses amorphous alloy materials as the magnetic core material. The core component of the transformer is the iron core, which plays a vital role in the working principle and performance of the transformer. The tensioning device applies appropriate pressure to tightly combine the various parts of the iron core, reducing loosening or deformation caused by vibration or external impact, thereby ensuring the normal operation and long-term stability of the transformer. Therefore, an amorphous alloy transformer iron core tensioning device is used;

[0003] To this end, the patent with announcement number CN205004142U discloses a core tensioning device for an amorphous alloy transformer, including a transformer base and an iron core located in the middle of the transformer base. The core tensioning device also includes a left clamp and a right clamp fixed to the transformer base, the left clamp and the right clamp facing each other and clamping the iron core in the middle; an intermediate pull plate is provided in the middle of the iron core, and insulating tubes are provided on both sides of the intermediate pull plate; a left pull plate and a right pull plate are provided on the inner sides of the left and right clamps facing each other, respectively; a screw passes through the through holes provided on the left clamp, the left pull plate, the intermediate pull plate, the right pull plate and the right clamp in sequence, as well as the insulating tubes located on both sides of the intermediate pull plate, and nuts are used to lock the two ends of the screw and the insulating tubes on both sides of the intermediate pull plate. The core tensioning device described in this utility model has a simple structure, is easy to install, has good stability, and has a good insulation effect;

[0004] Although the core tensioning device of the amorphous alloy transformer mentioned above locks the various components together through screws during use, it is inconvenient to move during use, making it inconvenient to make the core more uniformly stressed and to avoid damage or deformation caused by uneven stress, resulting in poor stability during use. Utility Model Content

[0005] The purpose of the utility model is to provide an iron core tensioning device for an amorphous alloy transformer, so as to solve the defect that the iron core tensioning device of the existing amorphous alloy transformer is inconvenient to move.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a core tensioning device for an amorphous alloy transformer, comprising a base and a tensioning plate;

[0007] An iron core body is provided at the top of the base, and a movable structure is provided at the top of the base, and the movable structure includes a built-in cavity, a threaded rod, a handwheel, a movable seat, a movable groove and a slider. The built-in cavity is opened at the top of the base, and movable grooves are opened inside the base on both sides of the built-in cavity. A threaded rod is provided inside the built-in cavity, and one end of the threaded rod extends to the outside of the base and is fixed with a handwheel. The outer sides of both ends of the handwheel are threadedly connected to the movable seat, and sliders are provided inside the movable grooves on both sides of the movable seat;

[0008] Both sides of the core body are provided with a protective structure, and one side of the protective structure is provided with a pull plate;

[0009] A pressing structure is provided on the top of the core body.

[0010] When the device is used, the movable structure is provided to realize the function of facilitating tensioning of the device, thereby improving the stability of the core tensioning device of the amorphous alloy transformer during use; the compression structure is provided to realize the function of facilitating compression of the device, thereby improving the applicability of the core tensioning device of the amorphous alloy transformer during use; and the protective structure is provided to realize the function of facilitating insulation of the device, thereby improving the safety of the core tensioning device of the amorphous alloy transformer during use.

[0011] Preferably, the threads at both ends of the threaded rod are in opposite directions, and the top end of the movable seat extends outside the base and is fixedly connected to the bottom end of the pull plate. When the handwheel is turned, the handwheel drives the threaded rod to rotate within the built-in cavity. Since the threads at both ends of the threaded rod are in opposite directions, the threaded rod drives the movable seats at both ends to move in opposite directions.

[0012] Preferably, the top end of the slider extends outside the base and is fixedly connected to the bottom end of the pull plate. The slider and base form a sliding structure via a movable slot. The movable seat drives the pull plate to move, and the pull plate drives the slider to move within the movable slot. The action of the slider enhances the stability of the pull plate during movement, thereby preventing damage or deformation caused by uneven force. The pull plate drives the insulating pad to be fixed to one side of the core body, thereby achieving a tight connection between the various parts of the core body.

[0013] Preferably, the compression structure includes a top plate, a rubber pad, a fixing nut, and a threaded post. The rubber pad is disposed at the top of the core body, the top plate being fixed to the top of the rubber pad. Threaded posts extend through both ends of the top plate, and fixing nuts are engaged with the outer sides of the threaded posts at the top of the top plate. Pressing the top plate causes the top plate to move outside the threaded posts, causing the top plate to drive the rubber pad to press against the top of the core body.

[0014] Preferably, the top plate and the threaded column form a sliding structure, and the bottom end of the threaded column is fixedly connected to the top end of the base. By turning the fixing nut with a wrench, the fixing nut moves outside the threaded column, fixing the fixing nut and the threaded column to each other, thereby causing the bottom end of the rubber pad to contact the top end of the core body, thereby preventing the core body from loosening.

[0015] Preferably, the protective structure includes an insulating pad, a chute, a rubber plate, and a connecting rubber plate. The insulating pads are arranged on both sides of the core body. The chute is evenly formed on one side of the interior of the pull plate. The chute is provided inside each rubber plate, and the connecting rubber plate is fixed to one side of each rubber plate. The insulating pad is moved to one side of the pull plate so that one end of the rubber plate contacts one end of the chute.

[0016] Preferably, the rubber sheet and the pull plate form a sliding structure via a chute, and one side of the connecting rubber sheet extends outside the pull plate and is fixedly connected to one side of the insulating pad. When the insulating pad is pulled, the insulating pad drives the rubber sheet into the chute via the connecting rubber sheet, effectively ensuring the insulation of the core body.

[0017] The utility model provides a core tensioning device for an amorphous alloy transformer, which has the following advantages:

[0018] By providing a moving structure, turning the handwheel, the handwheel drives the threaded rod to rotate inside the built-in cavity. Since the threads at both ends of the threaded rod are in opposite directions, the threaded rod drives the moving seats at both ends to move in opposite directions, the moving seat drives the pull plate to move, and the pull plate drives the slider to move inside the movable groove. Under the action of the slider, the stability of the pull plate during movement is enhanced, thereby avoiding damage or deformation caused by uneven force. The pull plate drives the insulating pad to be fixed to one side of the core body so that the various parts of the core body are tightly combined, realizing the function of facilitating tightening of the device, thereby improving the stability of the core tensioning device of the amorphous alloy transformer during use;

[0019] By providing a clamping structure, the top plate is pressed, and the top plate moves outside the threaded column, so that the top plate drives the rubber pad to press on the top of the core body. The fixing nut is rotated by a wrench, and the fixing nut moves outside the threaded column, so that the fixing nut and the threaded column are fixed to each other, and then the bottom end of the rubber pad is in conflict with the top end of the core body, thereby preventing the core body from loosening, realizing the function of facilitating clamping of the device, thereby improving the applicability of the core tensioning device of the amorphous alloy transformer when in use;

[0020] By providing a protective structure, the insulating pad is moved to one side of the pulling plate, so that one end of the rubber plate contacts one end of the slide groove, and the insulating pad is pulled. The insulating pad drives the rubber plate to move to the inside of the slide groove through the connecting rubber plate. Under the action of the insulating pad, the insulation of the core body is effectively guaranteed, and the function of facilitating insulation of the device is realized, thereby improving the safety of the core tensioning device of the amorphous alloy transformer when in use.
