Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a bottom support component for a transformer. Background Technology

[0002] Modern production and daily life are inseparable from electricity, and the transmission of electricity and the acquisition of various voltage levels are inseparable from transformers. Dry-type transformers are transformers whose cores and windings are not immersed in insulating oil. Dry-type transformers are mainly composed of a core made of silicon steel sheets and coils cast with epoxy resin. Dry-type transformers have advantages such as strong short-circuit resistance, low maintenance workload, high operating efficiency, small size, and low noise. They are often used in places with high performance requirements such as fire prevention and explosion prevention, and are widely used in local lighting, high-rise buildings, and airports. Vibration damping pads are usually installed between the windings and the base of dry-type transformers to support the transformer windings, reduce the vibration and noise of the core and windings, and ensure the stability of the core and windings.

[0003] Currently, the vibration damping blocks of dry-type transformers are usually placed directly on the two steel support beams of the transformer. This method of installation is not stable enough, and the damping blocks are prone to falling off the steel support beams during the installation of the iron core and windings, posing a safety hazard. Therefore, it is necessary to propose a more stable and safer bottom support for transformers. Utility Model Content

[0029] Please refer to Figures 1 to 3The transformer uses a bottom support component, including a support member 3. The support member 3 includes a first support element 31 and a second support element 32 arranged in parallel at intervals.

The top surface of the first support element 31 is provided with a receiving groove 4 along the length direction of the first support element 31. The top surface of the second support element 32 is provided with a receiving groove 4 along the length direction of the second support element 32.

The shock-absorbing pad 5 can slide in the receiving groove 4 along the length direction of the support member 3. The shock-absorbing pad 5 can slide along the length of the support member 3 within the receiving groove 4, thereby facilitating the operator to adjust the position of the shock-absorbing pad 5 to better support the transformer winding 1. In this embodiment, three shock-absorbing pads 5 are provided in each receiving groove 4, and the shock-absorbing pads 5 in two receiving grooves 4 are arranged in pairs.

The bottom surface of each shock-absorbing pad 5 has a threaded hole that mates with the locking bolt in the vertical direction. When the locking bolt is tightened, it secures the corresponding shock-absorbing pad 5. When the locking bolt is loosened, the corresponding shock-absorbing pad 5 can move within the receiving groove 4 along the length of the support component 3. Using locking bolts to fix the shock-absorbing pads 5 further improves their stability and enhances safety. In this embodiment, each shock-absorbing pad 5 is provided with one locking bolt, and the bottom surface of each shock-absorbing pad 5 has a threaded hole formed vertically, with the top of the threaded hole extending to the middle of the shock-absorbing pad 5.

When it is not necessary to move the bottom support of the transformer, the connecting rod can be adjusted so that the connecting rod drives the swivel wheel to retract from the opening into the movable element 7, thus preventing the bottom support of the transformer from moving.

[0038] Preferably, the bottom support for the transformer further includes multiple cooling fans, each of which is sequentially installed along the length of the support component 3 at the slots of the first support element 31 and the second support element 32, with the air outlet direction of the cooling fans facing upwards. The cooling fans are installed to cool the transformer core 2 and winding 1. The cooling fans are installed after all the shock-absorbing pads 5 are fixedly installed to avoid obstructing the installation of the locking bolts.
