Description

Technical Field

[0001] The invention relates to the technical field of transformers, in particular to a modified pole-mounted transformer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core (magnetic core). Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. It can be divided into power transformers and special transformers according to its use.

[0003] With the rapid development of society, transformers play an increasingly important role in human production activities. However, the installation of some transformers is very cumbersome, time-consuming, labor-intensive, and inflexible. At the same time, transformers will generate high-intensity vibrations during operation, which can cause some mounting bolts to loosen easily under long-term vibrations, resulting in loose installation of the transformer and some potential safety hazards. Therefore, a pole-mounted transformer modification is proposed to solve the above-mentioned problems. Summary of the invention

[0010] Preferably, the structure of the contact sleeve is arc-shaped, the surface of the contact sleeve is in contact with the surface of the mounting column, two limit plates are fixedly connected to the left side of the support rod, and the two limit plates are respectively located above the upper clamping plate and the lower clamping plate, and the internal thread of the threaded plate is connected to the surface of the rotating rod.

[0011] Preferably, there are two support rods, and the two support rods are symmetrically distributed with the center line of the beam as the symmetry axis. The inside of the support rod is rotatably connected to the surface of the fixed rotating rod, and the fixed rotating rod is located below the lower clamping plate.

[0015] Compared with the prior art, the present invention provides a pole-mounted transformer modification, which has the following beneficial effects:

[0016] 1. The column-mounted transformer is modified to achieve the rise or fall of the threaded plate by rotating the threaded plate. The support rod will drive the upper and lower clamping plates to move through the lever principle. After that, the contact sleeves on the two clamping plates will be squeezed and contacted with the surface of the mounting column to achieve clamping and fixation.

[0018] 3. The column-mounted transformer is modified, and multiple symmetrical groups of springs are set up to reduce the vibration of the transformer during its operation, reduce the impact of vibration force on the crossbeam and longitudinal beam, and further improve the stability of the overall mounting frame. At the same time, multiple groups of springs can also have the effect of relatively tightening and fixing the transformer.

[0019] 4. The pole-mounted transformer is modified by setting a slide groove inside the longitudinal beam to avoid the different installation distances of the two cross beams and to make them variable. At the same time, the two cross beams can be raised or lowered according to the different installation heights, so that the installation flexibility of the entire device is improved.

[0020] 5. The pole-mounted transformer is modified with a folding ladder installed inside the box door, so that the folding ladder can be taken out when the transformer is maintained, which is convenient for maintenance personnel to maintain the transformer equipment. There is no need for operators to directly climb the installation columns and beams, thereby improving the safety of maintenance personnel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1

[0030] See also Figure 1-4 A modified pole-mounted transformer comprises a mounting column 1, two cross beams 2 are arranged on the surface of the mounting column 1, a locking rod 11 is inserted inside the cross beam 2, two locking nuts 12 are threadedly connected to the surface of the locking rod 11, two longitudinal beams 3 are slidably connected inside the cross beam 2, a transformer body 7 is connected to the upper surface of the longitudinal beam 3 by bolts, two fixing plates 6 are welded to the upper surface of the transformer body 7, a buffer mechanism 10 is arranged on the surface of the fixing plate 6, the bottom of the cross beam 2 is connected to a chassis 4 by bolts, the bottom of the chassis 4 is rotatably connected to a rotating rod 8, and a mounting mechanism 5 is arranged on the surface of the rotating rod 8.

[0031] In this embodiment, the inside of the rotating rod 8 is slidably connected to a grounding tube 9. The design of the grounding tube 9 allows the chassis 4 to be well grounded to the ground, and some leakage current can be well introduced to the ground, thereby reducing the risk of electric shock. The grounding tube 9 is made of copper, and copper has a good conductive and drainage effect. A threading hole 91 is provided inside the grounding tube 9, and the designed threading hole 91 can provide a threading channel for the wires inside the chassis 4, making the introduction and withdrawal of wires safer.

[0032] Furthermore, there are two mounting columns 1, and the structure of the mounting columns 1 is conical. After the mounting columns 1 are set into a cone and are subjected to the deadweight of the transformer itself, the force is downward, thereby greatly reducing the looseness during the installation process. With long-term use, it will only become tighter and tighter. Increasing the distance between the two mounting columns 1 can improve the overall safety of the entire transformer and improve ventilation and heat dissipation.

[0033] Furthermore, two adjustment holes 21 are provided inside the cross beam 2 , the diameter of the adjustment hole 21 is larger than the diameter of the locking rod 11 , and a fixed rotating rod 13 is fixedly connected between the surfaces of the two cross beams 2 .

[0034] When the two beams 2 are raised or lowered, the installation spacing changes due to the change in the diameter of the installation column 1. The locking rod 11 is inserted into the adjustment holes 21 at different positions by using multiple adjustment holes 21 to facilitate the adjustment of the installation height position.

[0035] In addition, the mounting mechanism 5 includes a threaded plate 51, the surface of the threaded plate 51 is rotatably connected to a support rod 52, the left side of the support rod 52 is rotatably connected to a lower clamping plate 53 and an upper clamping plate 54, the upper clamping plate 54 is located above the lower clamping plate 53, and the upper clamping plate 54 is located on the left side of the lower clamping plate 53 and is fixedly connected to a contact sleeve 55.

[0036] The relative movement of the two support rods 52 can be driven directly by rotating the rotating rod 8, making the installation and fixing process simpler, saving time and effort.

[0037] In addition, the structure of the contact sleeve 55 is arc-shaped, and the surface of the contact sleeve 55 contacts the surface of the mounting column 1. Two limit plates 56 are fixedly connected to the left side of the support rod 52, and the two limit plates 56 are respectively located above the upper clamping plate 54 and the lower clamping plate 53. The internal thread of the threaded plate 51 is connected to the surface of the rotating rod 8.

[0038] The arc-shaped contact sleeve 55 can be in good contact with the mounting column 1, so that the contact area can be increased, the friction force can be increased, and the stability of the installation is improved. The limiting plate 56 limits the contact sleeve 55, so that when the gravity of the transformer deviates downward, the contact sleeve 55 will not flip clockwise when sliding up and down, providing a good limiting effect.

[0039] It is worth noting that there are two support rods 52, and the two support rods 52 are symmetrically distributed with the center line of the beam 2 as the symmetry axis. The inside of the support rod 52 is rotatably connected to the surface of the fixed rotating rod 13, and the fixed rotating rod 13 is located below the lower clamping plate 53.

[0040] By setting up two support rods 52, the surface of the contact sleeve 55 can be relatively squeezed and clamped on the surfaces of the two mounting columns 1, making the clamping and mounting process more stable. The two clamping plates are located above the fixed rotating rod 13, and the reaction of the lever is above the fixed rotating rod 13. The two clamping plates are used to perform double-sided installation of the mounting column 1 in the upper and lower positions to improve its stability.

[0041] Example 2

[0042] Please refer to Figure 4-6 On the basis of Example 1, in this embodiment, the buffer mechanism 10 includes a first spring 101 and a second spring 104, one end of the first spring 101 is clamped with an upper pull ring 102, and the other end of the first spring 101 is clamped on the surface of the fixed plate 6, one end of the second spring 104 is clamped with a lower pull ring 103, and the other end of the second spring 104 is clamped on the surface of the longitudinal beam 3, and the surfaces of the upper pull ring 102 and the lower pull ring 103 are respectively fixedly connected to the surfaces of the upper clamping plate 54 and the support rod 52.

[0043] A plurality of symmetrical groups of springs are provided to reduce the vibration of the transformer during operation, reduce the influence of the vibration force on the cross beam 2 and the longitudinal beam 3, further improve the stability of the overall mounting frame, and achieve the effect of relatively tightening and fixing the transformer.

[0044] In this embodiment, a slide groove 107 is opened inside the longitudinal beam 3, and the inner wall of the slide groove 107 is slidably connected to the limiting screw 105. The bottom of the limiting screw 105 passes through the interior of the longitudinal beam 3 and the cross beam 2 in turn and is connected to the internal thread of the limiting nut 106.

[0045] The slide groove 107 provided inside the longitudinal beam 3 is to avoid the two cross beams 2 being installed at different spacings and to allow for variable adjustment thereof. At the same time, the two cross beams 2 can be raised or lowered according to the different installation heights, thereby improving the flexibility of the entire device and making the installation process relatively simple.

[0046] It is worth noting that the front part of the chassis 4 is rotatably connected to a box door 41, and a folding ladder 42 is clamped inside the box door 41. By providing the folding ladder 42, the folding ladder 42 can be taken out when the transformer is maintained, which is convenient for maintenance personnel to maintain the transformer equipment. There is no need for operators to directly climb the installation column 1 and the beam 2, thereby improving the safety of maintenance personnel.

[0047] Working principle: when installing the transformer, the threaded plate 51 is raised or lowered by rotating it, and the rotating rod 8 is rotatably connected to the bottom of the chassis 4. When the threaded plate 51 rises, the support rod 52 will drive the upper clamping plate 54 and the lower clamping plate 53 to move through the lever principle, and then the contact sleeves 55 on the two clamping plates will be squeezed and contacted with the surface of the mounting column 1 to achieve clamping and fixing. The symmetrical structure can be directly installed and fixed on the surface of the two mounting columns 1.

[0048] First, the mounting column 1 is set to be conical, and is subjected to the deadweight of the transformer itself, and is forced downward. The entire support point is above the fixed rotating rod 13, and its own gravity will also squeeze and stress the upper half of the support rod 52, thereby greatly reducing the looseness during the installation process. With long-term use, it will only become tighter and tighter. At the same time, the installation process of the entire device is simple, convenient and fast. At the same time, during the squeezing and locking process, the two first springs 101 and the second springs 104 will also be driven to be pulled apart. The two first springs 101 and the second springs 104 tighten the transformer body 7 as a whole. A plurality of symmetrical groups of springs are provided, so that the vibration of the transformer during its own work can be reduced, and the transformer can be relatively tightened and fixed. Through the action of the limit screw 105, the transformer can slide relatively left and right on the beam 2.

[0049] Afterwards, it is fixed and locked by the action of the spring, and the slide groove 107 arranged inside the longitudinal beam 3 is to avoid the different installation spacings of the two cross beams 2 and to make it variably adjustable. At the same time, the two cross beams 2 can be raised or lowered according to the different installation heights. The locking rod 11 is inserted into the adjustment holes 21 at different positions by using multiple adjustment holes 21 to facilitate the adjustment of the installation height position. Finally, a folding ladder 42 is arranged inside the box door 41, so that when the transformer is maintained, the folding ladder 42 can be taken out, which is convenient for maintenance personnel to maintain the transformer equipment without the need for operators to directly climb the installation column 1 and the cross beam 2.
