Description

Technical Field

[0001] The utility model relates to the technical field of power transformer testing, in particular to an automatic rubber encapsulation testing machine for office power transformers. Background Art

[0002] The power transformer is a soft magnetic electromagnetic component whose functions are power transmission, voltage conversion and insulation isolation. It is widely used in power supply technology and power electronics technology. According to the size of the transmitted power, the power transformer can be divided into several grades: above 10kVA is high power, 10kVA~0.5kVA is medium power, 0.5kVA~25VA is low power, and below 25VA is micro power.

[0003] Existing testing machines cannot adapt to transformers of different specifications. One testing machine can only perform one test on the transformer. Therefore, after completing a test, the staff is often required to remove the transformer and place it in other project testing machines, which greatly slows down the testing rate of the transformer. At the same time, the test can only test one side of the transformer and cannot take into account both sides of the transformer. Errors will occur during the test and cannot meet the staff's usage needs.

[0004] To this end, we propose an automatic rubber encapsulation testing machine for office power transformers to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 An automatic rubber encapsulation tester for office power transformers includes a base 1, a plurality of feet 20 are arranged on the lower end surface of the base 1, and a worker can stably place the base 1 at a designated position through the plurality of feet 20, which facilitates the subsequent detection work. Two mutually symmetrical clamping structures are arranged on the upper end surface of the base 1, and the clamping structure includes a structural body 2 fixedly connected to the upper end surface of the base 1, and a rotating rod 3 runs through the structural body 2, and the rotating rod 3 is rotatably connected to the structural body 2;

[0021] A limit assembly is provided in the structural body 2, and the limit assembly includes a sliding opening 16 arranged on the structural body 2, and a limit rod 17 is slidably connected in the sliding opening 16. A plurality of positioning openings 18 are provided on the rotating rod 3, and the plurality of positioning openings 18 are matched with the limit rod 17. Through the above structure, the staff can pull the limit rod 17 to rise and leave the positioning opening 18, so that the rotating rod 3 can be rotated to perform the transformer flipping work, which is convenient for the staff to flip the transformer to a specified position. One end of the rotating rod 3 is fixedly connected to the flip rod 4, and a handle 19 is provided on the end of the rotating rod 3 away from the flip rod 4. The staff can conveniently rotate the flip rod 4 through the handle 19, so as to easily complete the flipping work;

[0022] A slot 5 is provided in the flip rod 4, and two sliders 6 are slidably connected in the slot 5 and are symmetrically arranged. The two sliders 6 are both threaded with a threaded rod 7. The ends of the two threaded rods 7 that are close to each other are fixedly connected, and the two threaded rods 7 are in opposite directions. The ends of the two threaded rods 7 that are away from each other both penetrate the flip rod 4. Through the above structure, when the staff rotates one end of the threaded rod 7, the two fixedly connected threaded rods 7 can rotate in opposite directions, so that the two sliders 6 can move relative to each other, so that the transformer can be clamped. The ends of the two sliders 6 that are away from the slot 5 are each provided with a clamping claw 8, and the side walls of the four clamping claws 8 that are close to each other are each provided with a protective layer. Through the protective effect of the protective layer, when the clamping claw 8 clamps the transformer, the situation of damage caused by extrusion is reduced. A test assembly is provided on the upper end surface of the base 1, and the test assembly includes a support block 9 fixedly connected to the upper end surface of the base 1, and one end of the support block 9 is provided with a bracket 10, and the end of the bracket 10 away from the support block 9 is provided with a rotating motor 11;

[0023] The rotating motor 11 is a prior art. By opening the rotating motor 11, the motor shaft of the rotating motor 11 can be rotated, and the object fixed on the motor shaft can be rotated at the same time. The motor shaft of the rotating motor 11 is fixedly connected to an operating panel 12. A detection device 13 is provided on the lower end surface of the operating panel 12, a detection device 2 14 is provided on the lower end surface of the operating panel 12, and a detection device 3 15 is provided on the lower end surface of the operating panel 12. The detection device 1 13, the detection device 2 14 and the detection device 3 15 are prior art, and can include three items of testing: appearance inspection of the transformer, insulation resistance inspection between the winding and the core, and power loss. The detection device 13 can be used to inspect the appearance ...

[0024] During the use of the utility model, the staff first places the base 1 at the designated position, and stably places the base 1 at the designated position through the foot 20 to complete the initial placement work, and then the staff takes out the rubber-coated power transformer, and then rotates the threaded rod 7 to make the four clamping claws 8 move relatively close until the power transformer is clamped stably, thereby completing the clamping task, and then the staff can open the detection device 13, and the detection device 13 automatically descends until it reaches the designated position to start the test work, and after completing the test work, the detection device 13 is closed and reset, and then the rotating motor 11 is turned on to rotate the detection device 2 14 to the designated position, and then the detection device 2 14 is turned on to make the detection device 2 14 automatically descend to the designated position and complete the test work, and the above operation is repeated to make the detection device 3 15 also complete the test work. The operator then turns off the rotating motor 11 and resets the operating panel 12 to its original position to complete the test on one end face of the transformer. At this time, the operator pulls the limit rod 17 to move the limit rod 17 away from the positioning port 18 and rotates the handle 19. Through the connection between the handle 19 and the flip rod 4, the flip rod 4 is rotated to drive the clamped transformer to flip over until it rotates to the specified position. The operator releases the limit rod 17 and, through the gravity factor of the limit rod 17 itself, the limit rod 17 slides down and enters another positioning port 18, thereby completing the restriction work and allowing the flip rod 4 to maintain a stable balance and not rotate. At this time, the operator can repeat the above operation so that the tester can test the other end face of the transformer, thereby completing the test of multiple items on both end faces of the power transformer, greatly reducing the work flow of the operator and improving the test efficiency.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
