Description

Technical Field

[0001] The utility model relates to the technical field of power transformers, in particular to a high-stability portable pole-mounted power transformer. Background Art

[0002] A power transformer is a static electrical device that is used to convert an AC voltage (current) of a certain value into another or several voltages (currents) of different values ​​with the same frequency. It is a static device with two or more windings. In order to transmit electrical energy, it converts the AC voltage and current of one system into the voltage and current of another system at the same frequency through electromagnetic induction. Usually, the values ​​of these currents and voltages are different.

[0003] At present, when installing the existing pole-mounted power grid transformer, most of them are directly placed on the preset mounting frame between two power poles, and then further fixed with bolts. Due to the large mass of the transformer, it needs to be installed by hoisting. After the transformer is hoisted to the top of the mounting frame, the position of the transformer bottom steel frame needs to be adjusted, and the corresponding support between the bottom steel frame and the preset mounting frame between the power poles is stable before unhooking.

[0004] However, the transformers currently on the market have smooth surfaces on the bottom steel frame and the top surface of the steel frame between the columns, making it difficult to control the position and distance during docking. In order to ensure the stability of the transformer, the safety of subsequent long-term use, and the aesthetics of the relative parallelism between the transformer and the column, it often takes a lot of time to adjust the position, the installation takes a long time, and the installation efficiency is average. Therefore, we propose to design a high-stability and convenient pole-mounted power transformer. Utility Model Content

[0026] See also Figure 1-4 The utility model provides a high-stability portable pole-mounted power transformer, comprising a transformer box 1, both sides of which are fixedly connected with heat dissipation fins 2.

[0027] A positioning assembly 3 is provided at the bottom of the transformer box 1, and the positioning assembly 3 includes two brackets 4 fixedly connected to the bottom of the transformer box 1, two clamping plates 5 are provided between the two brackets 4, and sliders 9 are fixedly connected at both ends of the two clamping plates 5. The sliders 9 at both ends of the clamping plates 5 respectively penetrate the bracket 4 on the corresponding side and are slidably connected to the inner wall thereof. The sliders 9 can slide in the bracket 4, so as to adjust the distance between the two clamping plates 5.

[0028] A notch 6 is provided at the bottom of the two clamping plates 5 on the side close to each other. The top of the notch 6 and the bottom of the bracket 4 are located in the same horizontal plane. When the bracket 4 is placed on the mounting frame between the electric poles to be installed, it is easy to be clamped on the mounting frame for positioning.

[0029] Positioning holes 13 are provided on both sides of the inner wall of the notch 6. The two ends of the bracket 4 are fixedly connected to the front positioning frame 7 and the rear positioning frame 8 respectively. A bidirectional threaded rod 10 corresponding to the slider 9 is provided between the front positioning frame 7 and the rear positioning frame 8. The bidirectional threaded rod 10 passes through the front positioning frame 7 and the rear positioning frame 8 in sequence. The bidirectional threaded rod 10 is connected to the bearing at the penetration of the front positioning frame 7 and the rear positioning frame 8, which is convenient for positioning the bidirectional threaded rod 10 and can be flexibly rotated in the positioning frame. The bidirectional threaded rod 10 passes through the sliders 9 at the ends of the two brackets 4 and is threadedly connected thereto. By rotating the bidirectional threaded rod 10, it is easy to drive the slider 9 to move, which is convenient for the staff to adjust.

[0030] The end of the bidirectional threaded rod 10 close to the rear positioning frame 8 is threadedly connected with a locking nut 11, which is screwed on the end of the bidirectional threaded rod 10 to fix the bidirectional threaded rod 10. The end of the bidirectional threaded rod 10 away from the locking nut 11 is fixedly connected with an adjusting button 12, which is convenient for the staff to turn the bidirectional threaded rod 10 to drive the bidirectional threaded rod 10 to rotate.

[0031] In this embodiment, the bracket 4 and the clamping plate 5 are both made of channel steel, which has a relatively large structural strength. As the bottom support of the transformer box 1, they have strong stability and ensure that the transformer is stably installed between the electric poles.

[0032] When in use, first measure and determine the distance between the mounting frames on the two electric poles, then simultaneously screw the two bidirectional threaded rods 10 to drive the two clamps 5 closer to each other, so that the distance between the notches 6 in the two clamps 5 corresponds to the size of the electric pole mounting frame, and then hoist the transformer box 1 to the top of the mounting frame.

[0033] The notches 6 at the bottom of the two clamping plates 5 can be just engaged with the edges of both sides of the mounting frame, so that the transformer can be quickly positioned, saving a lot of time and manpower. At this time, the locking nut 11 can be screwed to firmly fix the bidirectional threaded rod 10, and then the clamping plates 5 and the preset mounting frame on the electric pole can be further fixed by installing bolts through the positioning holes 13.

[0034] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
