Description

Technical Field

[0001] The utility model relates to the technical field of transformer winding testing equipment, in particular to a transformer winding deformation tester. Background Art

[0002] The transformer is the core equipment of the power supply system. The transformer winding refers to the circuit part of the transformer, which is wound by copper or aluminum wire with high conductivity. The degree of deformation of the transformer winding is a key factor in determining whether the transformer can continue to operate safely and stably. When the transformer winding is excessively deformed, it is necessary to use a reactance tester to test the degree of deformation of the transformer winding. However, the existing reactance tester for transformer winding deformation testing is easily damaged by accidental collision when idle, and its practicality is poor.

[0003] The prior art discloses a transformer winding deformation tester with publication number CN213515468U, which comprises a support box without a top wall, a mounting box without a top wall being fixed on the top of the support box, both sides of the inner bottom wall of the mounting box are rotatably connected with vertical screw rods through bearings, the outer rings of the two screw rods are spirally connected with a horizontal transmission plate, the outer ring of the screw rod located on the lower side of the transmission plate is fixedly sleeved with a first pulley, the middle position of the bottom wall of the mounting box is rotatably connected with a vertical rotating shaft through a bearing, the top end of the rotating shaft extends to the interior of the mounting box and is fixedly connected with a second pulley. The utility model has a novel design, can be effectively protected when idle, is not easily damaged by accidental collision, has high practicality, is easy to use, has high convenience, and is suitable for popularization and use.

[0004] Although the above technology provides protection for the internal test instrument through the external support box, and the instrument can be lifted out of the box for use when in use by lifting the transmission plate, the user still needs to use the pull ring and the crank handle in coordination during the process, which makes the storage and use of the entire instrument more cumbersome and not easy to carry. For this reason, we propose a transformer winding deformation tester. Utility Model Content

[0027] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0028] The utility model provides Figure 1-4A transformer winding deformation tester shown includes a main body 1, an instrument storage cavity 2 is provided at the middle end of the main body 1, and buffer plates 3 are distributed around the inner wall of the main body 1, the main body 1 includes a box 101, and a bottom pile 102 is distributed at the bottom end of the box 101, handles 103 are distributed at both ends of the box 101, and the buffer plates 3 are attached to the inner walls around the box 101;

[0029] In order to facilitate the carrying and protection of this instrument, Figure 1 As shown, when the deformation tester is in use, it can be carried by the handles 103 at both ends of the box 101, and can be kept stably placed with the rubber bottom piles 102 at the bottom of the box 101, so as to protect and stabilize the instruments stored inside.

[0030] like Figure 2-3 As shown, the instrument storage chamber 2 includes an instrument end 201, and slide rails 202 are distributed at both ends of the instrument end 201, and cover frames 203 are distributed on both sides of the instrument end 201, and one end of the cover frame 203 is connected to a rotating shaft 204, and gear shafts 205 are distributed at both ends of the rotating shaft 204, and one side of the gear shaft 205 is meshed with a rack frame 206, and screw holes 207 are opened in the middle of both ends of the instrument end 201, and the inner wall of the screw hole 207 is connected to a positioning screw 208;

[0031] In order to improve the convenience of using and storing this instrument, Figure 2-3 As shown, when the deformation tester is in use, the cover frame 203 on both sides of the box 101 can be rotated and unfolded, and the gear shaft 205 at one end of the cover frame 203 can be synchronously rotated to engage the rack frame 206, so that the instrument end 201 can be slid and exposed in cooperation with the unfolding of the cover frame 203, so as to facilitate the user's operation and use. The positioning screws 208 at both ends can be used to position and maintain the stability of the structure after unfolding and storing, which not only provides the protection and stability of the instrument, but also makes the storage and use of the instrument convenient.
