Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the description of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0019] The directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the utility model.

[0020] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0021] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0022] See also Figure 1 and Figure 2 The utility model provides an auxiliary device for debugging and testing a dry-type transformer, comprising a clamp head 1, a clamp 2, a connector and an insulating rope 4. The clamp head 2 is detachably connected to the clamp head 1 through the connector to form a clamping space, and the insulating rope 4 is clamped in the clamping space to form a preset clamping ring.

[0023] It can be known that when the metal clamp cannot clamp the copper busbar on the dry-type transformer well, that is, the two clamping plates of the metal clamp cannot be clamped, therefore, the purpose of the auxiliary device for the dry-type transformer debugging test is to enable the two clamping plates to remain clamped. When performing the clamping operation, first place the insulating rope 4 in the clamping space between the card 2 and the clamping head 1, so that the section of the insulating rope 4 outside the card 2 and the clamping head 1 forms a preset clamping ring, and the preset clamping ring can clamp the two clamping plates so that the two clamping plates are clamped.

[0024] See also Figure 1 In some embodiments, the chuck 1 includes a chuck body, a chuck body, a clamping groove 103 is opened on the chuck body, and the two ends of the clamping groove 103 extend to the two ends of the chuck body respectively, the card 2 is connected to the chuck 1 through the connecting piece 3, and the card 1 covers the clamping groove 103 to form a clamping space.

[0025] It can be understood that the clamping groove 103 can be across the length direction of the clamp head body, and the depth of the clamping groove 103 can be adapted to the insulating rope 4. The shapes and sizes of the card 2 and the clamp head 1 are adapted. The clamp head 1 of this structure has a simple structure and is convenient for clamping the insulating rope 4.

[0026] See also Figure 1 In some embodiments, the clamp body includes two main body sections 101 and a connecting section 102. The two main body sections 101 are connected by the connecting section 102. The main body section 101 includes a circular block and an extension block. The extension block is connected to one side of the circular block. The circular blocks of the two main body sections 101 are connected by the connecting section 102.

[0027] It can be understood that the extension block can be rectangular, the connecting section 102 can also be rectangular, and the clamping groove 103 can be arranged across the main section 101 and the connecting section 102, wherein the portion of the clamping groove 103 located on the extension block and the connecting section 102 can be rectangular, and the portion of the clamping groove 103 located on the circular block can be an adaptive circular shape. The clamping head body of this structure cooperates with the card 2 to clamp the insulating rope well, thereby maintaining the stability of the clamping ring.

[0028] Please continue reading Figure 3 In some embodiments, the connecting member includes at least two bolts 302 and two nuts 301. The two bolts 302 are respectively arranged on corresponding circular blocks. The nuts 301 are threadedly connected to the bolts 302 and are tightly attached to the card 2 so that a clamping space is formed between the card 2 and the clamping head 1. The card 2 includes a sheet body 201 and a through hole 202 opened on the sheet body 201. The bolts 302 are respectively inserted into the corresponding through holes 202 and connected to the corresponding nuts 301.

[0029] It is understandable that the bolt 302 can be welded on the circular block, and the head of the bolt 302 is located in the clamping groove 103 on the circular block. The connecting member 3 of this structure can conveniently realize the detachable connection between the card 2 and the clamp head 1.

[0030] See also Figure 4 In some embodiments, the insulating rope 4 includes two end sections, two clamping sections and a loop section. The two end sections are connected to the loop section through a clamping section respectively. The two end sections are located on one side of the clamp 1, the two clamping sections are clamped in the clamping space, and the loop section is located on the other side of the clamp 1.

[0031] It can be understood that the end section can be the part at both ends of the insulating rope 4, and the size of the loop section depends on the length of the end section. The longer the end section, the smaller the loop section. Correspondingly, the shorter the end section, the larger the loop section. The size of the loop section depends on the size of the metal clip.

[0032] From the above description, it can be known that in the auxiliary device for debugging and testing of dry-type transformers provided by the utility model, part of the insulating rope section is clamped in the clamping space between the card 2 and the clamping head 1, so that the section of the insulating rope 4 located outside the card 2 and the clamping head 1 forms a preset clamping ring, and the preset clamping ring can clamp the clamping plates of the two metal clamps so that the two clamping plates are clamped, thereby avoiding poor contact between the metal clamp and the copper busbar.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the attached claims.
