Seismic measures start with "transformers"! We achieve efficient disaster reduction measures (damage mitigation and early recovery).
The seismic isolation device "TTR type" significantly reduces the displacement of transformer terminal sections caused by large seismic motions, preventing large-scale power outages due to transformer damage. With the installation of TTR, a displacement of ±50mm or less at the terminal section has been achieved for all experimental seismic waves. Based on the building's response characteristics, it is possible to calculate and simulate the displacement of the transformer during an earthquake. In past earthquakes (such as those in Eastern Japan and Kumamoto), the heaviest transformers in the cubicles were damaged, resulting in many cases where emergency generators could not supply electricity even if they were intact. Transformers are not readily available, meaning that operations would be halted during that time. TTR not only protects the transformer but also enhances the overall rigidity of the cubicle, contributing to the protection of various relays and LCBs. TTR realizes efficient disaster mitigation measures. 【Features】 ■ Special absorbers at the top of the transformer significantly suppress displacement caused by seismic motions. ■ Effective even against continuous earthquakes. ■ Can be installed within the cubicle. ■ Minimal changes to panel size with TTR installation. ■ Does not compromise the effectiveness of the installed vibration isolation device. *For more details, please refer to the PDF document or feel free to contact us.
