[0003] The traditional installation method of the transformer is to install it on sheet metal or guide rails using self-tapping screws or screws. When installing the transformer, not only do the corresponding installation tools are required, but installation on the sheet metal surface will damage the sheet metal. In addition, after installation, it is impossible to ensure that the transformer and the wires remain perpendicular. This is very inconvenient during installation.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1-10 The present invention provides a technical solution: a transformer that is convenient to install, comprising a transformer body 1, an end of the transformer body 1 is fixedly connected to a base 11, and an end of the base 11 away from the transformer body 1 is provided with a guide rail 12;

[0033] The fixing mechanism 2 is located on both sides of the transformer body 1, and the transformer body 1 can be fixed on the guide rail 12 through the fixing mechanism 2;

[0034] The adjustment mechanism 3 is located outside the base 11. The adjustment mechanism 3 can adjust the angle of the transformer body 1 after the transformer body 1 is fixed to the guide rail 12 through the fixing mechanism 2;

[0035] When in use, the present invention fixes the transformer body 1 to the guide rail 12 through the fixing mechanism 2 by pressing the transformer body 1, which not only effectively saves installation time and labor costs and simplifies the operation process, but also reduces fatigue of the metal caused by repeated stress by abandoning the traditional method of fixing with screws, thereby preventing cracking of metal materials such as the guide rail 12 and sheet metal.

[0036] After the transformer body 1 is fixed by the fixing mechanism 2, the angle of the transformer body 1 can be changed by adjusting the knob 39 of the adjustment mechanism 3, so that the wires and cables can pass through the transformer body 1 in a vertical direction, effectively avoiding the destruction of the symmetry of the magnetic circuit due to the tilt of the transformer body 1, thereby preventing the magnetic saturation or leakage caused by the imbalance of the magnetic circuit from being aggravated.

[0037] The fixing mechanism 2 includes a bottom plate 21 disposed at one end of the base 11 away from the transformer body 1. A fixing shell 22 is fixedly connected to the surface of the bottom plate 21. The base 11 is located inside the fixing shell 22 and is slidably connected to the fixing shell 22. The bottom plate 21 includes fixing holes 23 opened on both sides of the transformer body 1. A reserved groove 24 is formed around the fixing hole 23. The reserved groove 24 is located at the end of the bottom plate 21 away from the transformer body 1.

[0038] After the bottom plate 21 is fixed to the surface of the guide rail 12 by the fixing mechanism 2, the direction and angle of the transformer body 1 can be adjusted by adjusting the position of the base 11 inside the fixed shell 22 to ensure that the transformer body 1 can be installed perpendicular to the wires and cables. When installed vertically, the transformer body 1 can more effectively receive electromagnetic signals in the wires. When the transformer body 1 is perpendicular to the wires, it can more fully cut the magnetic lines of force, so that the current induced inside the transformer more accurately reflects the actual current in the wires, reducing the measurement error caused by improper installation angle, ensuring the reliability of the measurement data, and providing an accurate basis for monitoring and scheduling of the power system; at the same time, vertical installation of the transformer body 1 helps the transformer body 1 to remain stable during operation. The transformer body 1 will generate a certain electromagnetic force and vibration during operation. Vertical installation can make the direction of these forces and vibrations more coordinated with the direction of gravity, reducing the position offset or loosening of the transformer body 1 caused by external forces. During long-term operation of the transformer body 1, the vertical installation method can better withstand the influence of its own weight and external vibration, reduce the risk of equipment failure, and extend the service life of the transformer body 1.

[0039] A trigger member 5 capable of triggering the fixing member 4 is provided inside the fixing hole 23. The trigger member 5 includes a trigger rod 51 slidably connected to the fixing hole 23. A reserved disk 52 is fixedly connected to the end of the trigger rod 51. The reserved disk 52 is located inside the reserved groove 24 and is slidably connected to the reserved groove 24. A trigger plate 53 is fixedly connected to the end of the trigger rod 51 away from the reserved disk 52. The trigger plate 53 is hook-shaped.

[0040] A baffle 54 is fixedly connected to the end of the bottom plate 21 near the trigger plate 53. A spring 1 55 is fixedly connected to the end of the baffle 54 away from the trigger rod 51. A slide 56 is fixedly connected to the end of the spring 1 55 away from the baffle 54. The slide 56 is located inside the trigger plate 53 and is engaged with the trigger plate 53. The end of the slide 56 away from the spring 1 55 is fixedly connected to the push rod 57. A limit ring 58 is fixedly connected to the outer wall of the bottom plate 21. The limit ring 58 is located outside the push rod 57 and is slidably connected to the push rod 57.

[0041] When installing and fixing the transformer body 1, align the transformer body 1 with the guide rail 12 and press it. At this time, the reserved plate located at the end of the bottom plate 21 away from the transformer body 1 abuts against the guide rail 12, and the reserved plate drives the trigger rod 51 to slide in the fixing hole 23 until the reserved plate slides into the reserved groove 24. At this time, the bottom plate 21 is tightly attached to the guide rail 12, and at the same time, the trigger rod 51 can drive the trigger plate 53 to slide when it slides in the fixing hole 23. At this time, the trigger plate 53 no longer hooks the slide plate 56, and the slide plate 56 is lifted up by the spring 55. Since the baffle 54 is fixed on the surface of the bottom plate 21, the slide plate 56 slides toward the end away from the baffle 54. The limit ring 58 can limit the sliding direction of the push rod 57. When the slide plate 56 drives the push rod 57 to slide inside the limit ring 58, it can drive the fixing part 4 to fix the guide rail 12.

[0042] A fixing member 4 is provided at the end of the bottom plate 21 for fixing the guide rail 12. The fixing member 4 includes a fixing groove 41 opened at the end of the bottom plate 21. The fixing groove 41 corresponds to the position of the push rod 57. A fixing rod 42 is fixedly connected to the inner wall of the fixing groove 41. A fixing ring 43 is rotatably connected to the outer periphery of the fixing rod 42. A fixing hook 44 is fixedly connected to the outer wall of the fixing ring 43. The fixing hook 44 is rotatably connected to the fixing rod 42.

[0043] A fixing plate 45 is fixedly connected to the outer wall of the fixing ring 43. The fixing plate 45 is rotatably connected to the fixing rod 42. The fixing plate 45 and the fixing hook 44 are at right angles.

[0044] When the push rod 57 slides, the push rod 57 can push the fixing plate 45, so that the fixing plate 45 drives the fixing ring 43 to rotate around the fixing rod 42. Since the fixing plate 45 is at right angles to the fixing hook 44, when the fixing plate 45 rotates to be parallel to the pushing rod 57, the fixing hook 44 hooks the guide rail 12. At this time, the fixing hook 44 can fix the base plate 21 on the surface of the guide rail 12; the installation method without using screws only requires simple operations to complete the installation, which greatly shortens the installation time and improves work efficiency. For example, in some large-scale substation construction, the use of screw-free installed transformers can quickly complete the installation and commissioning of the equipment, so that the progress of the entire project is effectively promoted; and the installation method without screw drilling is suitable for more installation scenarios, and at the same time avoids the phenomenon that the screws in the traditional screw fixing method loosen due to thread wear or insufficient pre-tightening force in a vibration environment. The installation is quick and convenient, safe and firm.

[0045] The adjusting mechanism 3 includes a universal groove 31 opened at one end of the base 11, a universal ball 32 is rotatably connected inside the universal groove 31, a support rod 33 is fixedly connected between the universal ball 32 and the inner wall of the fixed shell 22, a spring 2 is fixedly connected to one end of the base 11, the end of the spring 2 34 away from the base 11 is fixedly connected to the inner wall of the fixed shell 22, the spring 2 34 is located at the end of the base 11 close to the universal ball 32, a slider 35 is provided at the end of the base 11 away from the spring 2 34, the slider 35 is slidably connected to the base 11, and a plurality of teeth 36 are fixedly connected to the end of the slider 35 away from the base 11, a positioning rod 37 is fixedly connected to the end of the bottom plate 21 close to the transformer body 1, a gear 38 is rotatably connected to the periphery of the positioning rod 37, the gear 38 is meshed with the teeth 36, and a knob 39 is fixedly connected to the end of the gear 38 away from the bottom plate 21, and the knob 39 is located on the outside of the fixed shell 22;

[0046] After fixing the transformer body 1, the angle of the transformer body 1 can be adjusted by rotating the knob 39. When the knob 39 is rotated, it can drive the gear 38 located on the periphery of the positioning rod 37 to rotate. Since the gear 38 meshes with the teeth 36 on one side of the slider 35, the gear 38 can drive the slider 35 to slide when it rotates. At this time, the slider 35 squeezes the base 11, causing the base 11 to rotate around the universal ball 32. The universal ball 32 is located in the universal groove 31 provided in the base 11 and can rotate in any direction. The spring 2 34 at one end of the base 11 can ensure that the base 11 maintains a stable posture when the slider 35 slides. By changing the direction of the knob 39, the angle of the transformer body 1 can be adjusted, ensuring that the wires and cables pass through the transformer body 1 vertically. The installation of the transformer body 1 vertically with wires is more convenient during maintenance and repair. Technicians can more intuitively observe the operating status of the transformer body 1 and check whether the wiring is loose or the insulation is good. Moreover, when replacing or repairing the transformer body 1, the vertical installation method facilitates operation, reducing the difficulty and time cost of maintenance work.
