"Transformer Seismic Resistance: Even if the emergency power generation is safe, the transformer is important." TTR
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 power outages due to damage at the terminal sections. With the installation of the TTR, a displacement of ±50mm or less at the terminal sections has been achieved for all experimental seismic waves. It is possible to calculate and simulate the displacement of transformers during earthquakes based on the building's response characteristics. In past earthquakes (such as those in Eastern Japan and Kumamoto), the heaviest transformers in substations were damaged, leading to many cases where electricity could not be extracted even if emergency generators were intact. Transformers are not readily available, meaning that operations would be halted during that time. The TTR not only protects the transformer but also enhances the overall rigidity of the substation, contributing to the protection of various relays and LCBs. It enables efficient disaster mitigation measures (damage reduction and early recovery). 【Features】 ■ Special absorbers at the top of the transformer significantly suppress displacement caused by seismic motions. ■ Effective against continuous earthquakes. ■ Can be installed within substations. ■ 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.
