Description

Technical Field

[0001] The utility model relates to the technical field of transformer equipment, in particular to a transformer core grounding lead structure. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components include a primary coil, a secondary coil and an iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization (magnetic saturation transformer).

[0003] The transformer core grounding lead structure is a key part to ensure the normal operation and safety of the transformer. The main purpose of transformer core grounding is to eliminate the floating potential generated by the core and avoid the potential difference between the core and the oil tank, thereby preventing intermittent discharge. Under normal circumstances, the transformer core is not allowed to be grounded at multiple points to ensure its safe and stable operation.

[0004] In terms of specific structure, the grounding lead of the transformer core is usually achieved through a specific grounding device, which may include an epoxy grounding plate, a grounding wire and other connecting parts. The epoxy grounding plate is connected to the oil tank at the bottom of the core, and the core, clamps and other key components are grounded through the grounding wire. The entire grounding device needs to ensure good electrical connection and insulation performance to prevent electrical failures and safety hazards.

[0005] At present, the grounding wire on the transformer core grounding lead structure is directly connected to the outside of the transformer, and the connection between the core grounding lead and the connecting wire and the connecting wire and the grounding wire are mostly fixed by a single bolt.

[0006] This results in poor connection between the core grounding lead wire and the connecting wire, and between the connecting wire and the grounding wire, making the lead wire loose and easily pulled during daily use, causing danger. Because the grounding wire is outside the transformer and has no protective structure, the grounding wire will be exposed to sunlight when used for a long time, which will accelerate the aging of the grounding wire and reduce its service life. Utility Model Content

[0007] Based on this, the purpose of the utility model is to provide a transformer core grounding lead structure to solve the technical problems in the prior art that the grounding wire is relatively loose in firmness and that the grounding wire will age faster when exposed to sunlight for a long time, thus affecting its service life.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a transformer core grounding lead structure, comprising a transformer body, a grounding wire body connected to one side of the transformer body, a fixed block fixedly installed on the right side of the transformer body, an arc-shaped groove used in conjunction with the grounding wire body opened in the fixed block, a first gas storage block fixedly connected in the fixed block, a first movable block movably installed in the first gas storage block, a first movable rod fixedly connected to the right side of the first movable block, a second pressure block fixedly connected to the top of the first movable rod, the second pressure block is located on the outer surface of the fixed block, clamping blocks are symmetrically arranged on both sides of the fixed block, a second gas storage block used in conjunction with the first gas storage block is arranged on the inner side of the fixed block, a second movable block movably installed in the second gas storage block, a second movable rod is fixedly connected between the second movable block and the clamping block, and a first pressure block used in conjunction with the second pressure block is arranged on the right side of the transformer body.

When the first pressing block is continuously pressed toward the grounding wire body, the second pressing block can continuously move toward the fixed block, so that the first movable rod and the first movable block are squeezed inwardly, and then the gas in the first gas storage block is squeezed, so that the gas in the first gas storage block enters the second gas storage block, and then the second movable block in the second gas storage block cooperates with the first movable rod to move the second movable block outwardly, so that the clamping block can clamp the grounding wire body, so that the grounding wire body is clamped and fixed, so as to solve the technical problem that the connection firmness between the grounding lead wire and the connecting wire and the connecting wire and the grounding wire in the prior art is poor, the lead wire is relatively loose, and it is easy to be pulled and dangerous in daily use, thereby improving the practicality and stability of the entire device.

[0010] The utility model is further configured that a protective shell is arranged on the right side of the transformer body, fixed connecting members are fixedly installed on both sides of the protective shell, and the fixed connecting members are fixedly connected to the transformer body.

[0011] By adopting the above technical solution, the fixed connecting parts can fix the protective shell on both sides of the transformer body.

[0012] The utility model is further configured such that a support leg is fixedly installed at the bottom of the transformer body, and an anti-rust coating is provided on the outer side of the protective shell.

[0013] By adopting the above technical solution, the supporting legs are provided to facilitate the installation and fixation of the entire device, and the anti-rust coating on the outside of the protective shell can increase the anti-corrosion and anti-rust effect of the protective shell, thereby improving the service life of the protective shell.

[0014] The utility model is further configured such that air guide pipes are fixedly connected to both sides of the first air storage block, and an air delivery pipe is fixedly connected between the air guide pipe and the second air storage block.

[0015] By adopting the above technical solution, the provided air guide pipe and the air delivery pipe cooperate with each other, so as to squeeze the gas in the first gas storage into the second gas storage block for use.

[0016] The utility model is further configured such that a spring is fixedly connected between the first gas storage block and the first movable block.

[0017] By adopting the above technical solution, the spring is provided so that the first movable block can move more smoothly in the first gas storage block, and the performance of the spring itself can assist the first movable block in resetting.

[0018] The utility model is further configured such that outer surfaces of the first pressing block, the second pressing block and the clamping block are all provided with rubber structures.
