Description

Technical Field

[0001] The utility model relates to the technical field of transformers, and more specifically to a support bar structure for internal support of a transformer coil. Background Art

[0002] The support bar structure inside the transformer coil is a structure used to support the transformer coil. It is usually made of insulating material and installed inside the coil to provide additional support and keep the shape of the coil stable.

[0003] The design of the bracing structure can be adjusted according to the specific transformer requirements. It can be a single or multiple braces, distributed along the length of the coil. The braces are usually fixed at both ends or in the middle of the coil and fixed to the frame of the transformer by support rings or other fixing devices.

[0004] Among them, after searching, it was found that the utility model patent with patent application number CN201921915841.X disclosed a support bar structure for the internal support of the transformer coil, which belongs to the technical field of large-scale power transformer manufacturing. The technical solution is: a notch is opened at the upper end of the marked length support bar, one end of the marked length support bar to the notch is the actual support bar, and the other end of the marked length support bar to the notch is the redundant support bar, and the length of the actual support bar is the same as the axial height of the transformer coil; the lower end surface of the marked length support bar is pasted with the lower layer of insulating paper.

[0005] When the structure is in use, slots are made on the standard length support bars, and the operator breaks them off at the slots after wrapping. This can simplify drawings, promote design standardization, reduce labor intensity, improve work efficiency, and eliminate safety hazards. However, the structure is only a single support bar when in use, and it is not easy to position the coil, resulting in poor support performance. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a support bar structure for internal support of a transformer coil, aiming to solve the problems raised in the above-mentioned background technology.

[0007] The utility model is implemented in this way. The utility model provides the following technical solutions: a support bar structure for internal support of a transformer coil, comprising a support body, one side of the support body is stacked with a plurality of clamping assemblies;

[0008] The clamping assembly comprises an extension piece arranged on one side of the support body, and a limiting piece for limiting the position of the coil is arranged on the outer side of the extension piece;

[0009] The limiting member is provided with a dislocation opening for clamping the coil, and the inner wall of the dislocation opening is provided with a plurality of limiting cavities for combing the coil.

[0010] It can be seen that in the above technical solution, the interference between the limiting member and the coil is staggered by the offset opening, and the coil is combed and clamped by each limiting cavity, so as to improve the supporting stability of the device when in use.

[0011] Optionally, in a possible implementation manner, a protective sleeve is provided on the outside of the extension piece and inside the limiting piece, and the protective sleeve is sleeved on the extension piece and detachably connected to the extension piece.

[0012] Optionally, in a possible implementation manner, limiting columns are provided on the top and the bottom of the protective sleeve.

[0013] Optionally, in a possible implementation manner, a slip ring is movably connected to each of the two limiting columns, and each of the slip rings is mounted on the limiting member.

[0014] Optionally, in a possible implementation manner, a docking rod is provided at one end of the extension piece, and a slot for limiting is provided in the middle of the docking rod.

[0015] Optionally, in a possible implementation manner, a docking block detachably connected to the support body is provided in the slot, and buckles that are mutually engaged are provided on the docking block and the docking rod.

[0016] It can be seen that in the above technical solution, the slip ring is driven to rotate along the axial point of the connection between the slip ring and the limit column by rotating the limit member, so the angle and position of the limit member can be easily adjusted according to needs, thereby improving the adaptability of the device during use, and through the setting of the docking block, the buckle and the docking rod, the user can increase the number of extension members and limit members according to needs. The docking block and the docking rod are clamped together by the slot and the buckle, which makes it easy to disassemble the extension member, so that the device can adapt to different working environments during use.

[0017] Technical effects and advantages of the utility model:

[0018] By setting the clamping assembly, compared with the prior art, the overall design is simple and the structure is reasonable. Through the corresponding coordination of various structures, the interference between the limiting member and the coil is staggered through the staggered opening, and the coil is combed and clamped through various limiting cavities, so as to improve the support stability of the device when in use;

[0019] When the device is in use, the slip ring can be driven to rotate along the axis point of the connection between the slip ring and the limit column by rotating the limit member, so that the angle and position of the limit member can be easily adjusted according to needs, thereby improving the diversity of the device when in use.
