Power Supply BCP Measures: Seismic Device for Transformers 'TTR Type'

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 was 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 substations were damaged, leading to many cases where emergency generators were intact but electricity could not be extracted. 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 rigidity of the entire substation, 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 motion ■ 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.
