Description

Earthquake-proof and vibration-proof system for electric transformer}

The present invention relates to an earthquake-proof and vibration-proof system for an electric transformer. More specifically, it prevents vibrations generated by the operation of the transformer from being transmitted directly to the ground where the transformer is placed, and also prevents vibrations from being transmitted directly to the ground, such as earthquakes, at a certain level. This relates to a vibration-proof and vibration-proof system for an electric transformer that can effectively prevent damage to the transformer by adding an additional gel-like cushioning material around the lower part of the transformer when the above impact is applied from the outside.

In general, although transformers are key devices that supply electricity, they are the subject of complaints by residents living near substations due to their high noise-generating characteristics, which not only disrupts effective power supply but also causes work loss for substation workers.

This phenomenon is getting worse as urban centers expand and residential areas come closer to substations, and new substations are built in urban areas.

Meanwhile, in the case of the outdoor type, such a transformer is fixed on the ground using a fixing means, and in the case of an indoor type, a large transformer is placed on a support structure and then operated by fixing its position using a fixing means.

Meanwhile, the purpose of fixing the transformer to the ground is to prevent loss of function that occurs when the transformer is displaced due to external shocks such as an earthquake. However, by fixing the transformer, the noise propagated outside the transformer increases due to vibration amplification of the transformer itself. In addition, as the transformer vibration is transmitted to the ground, it affects the soundness of structures around the transformer. In particular, in the case of indoor transformers, the transformer support structure is often damaged due to the magnitude of the transformer.

For this purpose, conventionally, checkerboard-shaped ribs are formed on the bottom of the transformer, and rubber pads designed to have a natural frequency of 10 Hz or less are arranged at a slight distance from each other and are installed in contact with the bottom of the transformer, and are attached to the lower fixing flange of the transformer. A dust-proof cap configured to be fixed to the ground by a fixing means is installed to surround the side of the lower fixing flange, and the dust-proof cap is fastened by the fixing means to an insertion groove into which the lower fixing flange is inserted and received. It was designed to be constructed with a suitable support.

However, in the prior art, the checkerboard-shaped ribs are effective in controlling only low-frequency vibration, and may have little effect on high-frequency vibration, and the rubber pad hardens and wears over time, reducing the vibration control effect. Gaps between pads may not effectively absorb vibration energy.

In addition, rubber pads must be installed and replaced individually, which takes a lot of time and effort, and if the rubber pads are damaged or worn, they must be inspected and replaced regularly.

In addition, if the fixing means is corroded, the dustproof cap may fall off, and it is difficult to always recognize the state of corrosion of the fixing means, such as a metal screw member fixed to the ground, and if the fixing means is corroded and damaged, the transformer itself cannot be dust-proofed. There is a problem that cannot be resolved.

The staggered arrangement of the sound-absorbing partition walls 410 between layers can maximize the effect of absorbing noise of various frequencies.

Additionally, the sound-absorbing panel 400 can absorb vibration energy to further reduce the vibration of the case.

In addition, the sound-absorbing panel 400 can further seal the gap between the bottom of the case and the support portion to more effectively prevent the intrusion of dust, moisture, noise, etc.

Additionally, the combination of improved sealing effect and sound absorption effect can further improve the dustproof effect.

Furthermore, the sound-absorbing panel 400 together with the corrugated pipe 21 and the lower pad 250 of FIG. 3 can further improve the earthquake-proof and dust-proof effects.

The configuration according to FIGS. 4 and 5 can contribute to more effective protection of the electric transformer and ensure stable power supply through sound absorption effect, vibration reduction effect, improved sealing effect, and improved dustproof effect.

The vacuum space 211 of the elastic spring 210 is connected to the vacuum tube 212. The vacuum tube 212 receives vacuum from the vacuum provider 213 and provides it to the vacuum space 211.

When the external shock is transmitted, the controller 340 may provide vacuum to the vacuum space 211 using the vacuum provider 213 to increase the vacuum at a set rate for the transmitted external shock.

The effects of the configuration according to FIG. 8 are as follows.

The vacuum space 211 inside the elastic spring 210 absorbs vibration energy and reduces vibration. The vacuum condition prevents the transmission of noise and vibration and also contributes to the anti-vibration effect.

Additionally, the vacuum space 211 controls the deformation of the elastic spring 210 caused by external shock to alleviate the shock. The controller 340 can adjust the vacuum degree of the vacuum space 211 according to the situation to optimize the impact mitigation effect.
