Description

Technical Field

[0001] The utility model relates to the field of electrical engineering, in particular to a transformer core grounding fault diagnosis simulation device. Background Art

[0002] A transformer core grounding fault diagnosis simulation device is an experimental device used to simulate and analyze transformer core grounding faults. This device can help engineers and technicians better understand the causes, effects, and solutions of transformer core grounding faults, thereby improving the operational reliability and safety of the transformer. The current transformer core grounding fault diagnosis simulation device can only adapt to a fixed height during detection. When faced with transformers of different heights, multiple people are required to cooperate in lifting for detection. However, considering the huge weight of the transformer itself, the process of multiple people lifting not only poses a safety hazard, but also wastes a lot of human resources. For this reason, we propose a transformer core grounding fault diagnosis simulation device. Utility Model Content

[0025] See also Figure 1-5 A transformer core grounding fault diagnosis simulation device includes a base plate 1, vertical side plates 2 are fixedly provided on the top of the base plate 1 near both ends, a transformer 3 is slidably connected to the side plates 2, a crossbeam 10 is fixedly provided between the two sets of side plates 2 near the bottom, and a double-rod hydraulic cylinder 14 is fixedly installed on the top of the base plate 1 corresponding to the side of the crossbeam 10 (a double-rod hydraulic cylinder is a hydraulic cylinder with piston rods on both sides of the piston, generally bidirectional hydraulic drive, which can achieve constant speed reciprocating motion. A double-rod hydraulic cylinder is an actuator in a hydraulic system, which can convert the pressure energy of the liquid into mechanical energy, thereby generating linear reciprocating motion. Its structure mainly consists of five parts: a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. Since there are piston rods on both sides of the piston, the double-rod hydraulic cylinder can achieve constant speed reciprocating motion when working. This is because the effective working area on both sides is equal, and the thrust and speed are consistent in both directions). It also includes:

[0026] A height adjustment component, which is installed at the bottom of the transformer 3 and is used to adjust the height of the transformer 3;

[0027] The sliding assembly is mounted on the crossbeam 10 and is used to enhance the stability when adjusting the height of the transformer 3 .

[0028] A horizontal transformer base 4 is fixed at the bottom of the transformer 3. The transformer 3 is slidably connected to the two sets of side panels 2 through the transformer base 4. The hinge 5 pulls the transformer base 4 to slide downward on the two sets of side panels 2 through the gradual descent of the two sets of rocker arms 8, thereby adjusting the height of the transformer 3.

[0029] The height adjustment assembly includes a hinge seat 5, an empty slot 6, a rotating shaft 7 and a rocker 8. Two sets of hinge seats 5 are fixed at the bottom of the transformer base 4. The bottoms of the two sets of hinge seats 5 are each provided with an empty slot 6. A rotating shaft 7 is fixed between the inner walls on both sides of the empty slot 6. A rocker 8 is rotatably sleeved on the rotating shaft 7. The two sets of rockers 8 are cross-shaped and the corresponding sides of the two sets of rockers 8 are tightly fitted. The two sets of hinge rods 12 respectively drive one end of the two sets of rockers 8 away from each other through the displacement of the two sets of fitting sliders 13.

[0030] The height adjustment assembly also includes a connecting spindle 9, which is provided at the intersection of the two sets of rocker arms 8. The two sets of rocker arms 8 are rotatably sleeved on the connecting spindle 9, and the intersection of the two sets of rocker arms 8 rotates on the connecting spindle 9, and the other ends of the two sets of rocker arms 8 rotate on the rotating shaft 7 in the empty slot 6 and gradually descend.

[0031] The movable rods at both ends of the double-rod hydraulic cylinder 14 are both sleeved with clamping seats 15, and an opening slot is opened on one side of the clamping seat 15. When the height of the transformer 3 needs to be adjusted, the double-rod hydraulic cylinder 14 is first started, so that the piston rods at both ends of the double-rod hydraulic cylinder 14 drive the two sets of clamping seats 15 to retract or extend outward.

[0032] The crossbeam 10 is provided with a cross groove 11 which passes through both sides of the crossbeam 10 , and a limit groove 17 is provided in the cross groove 11 . The block 16 on the fitting slider 13 slides synchronously in the limit groove 17 to prevent the fitting slider 13 from shifting in position when sliding.

[0033] The sliding assembly includes a hinge rod 12, a fitting slider 13 and a block 16. The two sets of rockers 8 are rotatably connected to the hinge rod 12. One end of the hinge rod 12 is sleeved with the fitting slider 13. The fitting slider 13 is sleeved with the block 16. The block 16 is slidably connected in the limit groove 17. The fitting slider 13 is slidably connected in the transverse groove 11. The end of the fitting slider 13 is clamped in the open groove. When the two sets of movable rods extend outward, the two sets of clamping seats 15 are respectively clamped with the two sets of fitting sliders 13 through the open groove so that the two sets of fitting sliders 1 The two sets of sliding blocks 13 slide away from each other in the horizontal groove 11 on the crossbeam 10. The two sets of clamping seats 15 on the double-rod hydraulic cylinder 14 enable the fitting slider 13 to slide on the crossbeam 10. By moving the two sets of fitting sliders 13 away from or closer to each other, the two sets of rocker arms 8 can adjust the height of the transformer 3. By adjusting the height of the transformer 3, the device is made more flexible and can be used to test transformers of different heights, eliminating the steps and time of manual handling of the transformer and improving the testing efficiency.

[0034] When the two movable rods are extended outward, the two clamping seats 15 are respectively engaged with the two sets of fitting slides 13 through the open slots, so that the two sets of fitting slides 13 slide away from each other in the transverse slots 11 on the crossbeam 10, and the blocks 16 on the fitting slides 13 slide synchronously in the limit slots 17 to prevent the fitting slides 13 from shifting when sliding. The two sets of hinge rods 12 drive one end of the two sets of rocking arms 8 away from each other through the displacement of the two sets of fitting slides 13, and the cross position of the two sets of rocking arms 8 rotates on the connecting main shaft 9, and the other ends of the two sets of rocking arms 8 rotate on the rotating shaft 7 in the empty slot 6 and gradually descend. The hinge seat 5 pulls the transformer base 4 to slide downward on the two sets of side plates 2 through the gradual descending of the two sets of rocking arms 8, thereby adjusting the height of the transformer 3.
