[Information] Shirutoku Report No. 68 # Types and Roles of Breakers

The breakers lined up in the distribution board are of different types according to their purposes!

★★Shirutoku Report: Useful Information You Should Know★★ The Power Supply Design Department designs various types of switching power supplies, such as AC-DC converters and DC-AC inverters, and conducts various evaluations and tests specific to power supplies. Among these tests, there are rigorous evaluations known as "abnormal tests," which assess safety during component failures. One of the important devices that protects the evaluation equipment during such harsh tests is the "circuit breaker." Many may be more familiar with the term "breaker." This report will introduce you to these breakers. 【Contents】 ■ Ampere Breaker: Maintains the current value contracted with the power company ■ Leakage Breaker: Protects commercial systems held by households and power companies from accidents ■ Safety Breaker: Maintains the current value for each circuit (each room) *For more details, please refer to the PDF document or feel free to contact us.

Case studies of traffic barriers installation on bridges

It is also expected to prevent secondary disasters caused by mistakenly entering due to overlooking signs and boards!

In the case of bridges, following the damage caused by Typhoon No. 21 in 2018, pre-traffic regulations have been implemented in areas where certain wind speeds are anticipated, with the aim of preventing the expansion of damage and avoiding traffic confusion caused by sudden regulations. This has been discussed and introduced in various locations. Our company has examples such as the installation of the "SG-1 type" in Amagasaki City, Hyogo Prefecture (existing bridge) and the installation of the "SG-3 type" in Kawasaki City, Kanagawa Prefecture (new bridge). We have introduced these examples with photographs, and we hope they will be helpful for your considerations regarding implementation. 【Examples (excerpt)】 ■ Amagasaki City, Hyogo Prefecture (existing bridge) - SG-1 type (one unit for each lane on one side, fully closed with double doors) - A tarpaulin sign that wraps and stores is deployed when barriers are in place. ■ Kawasaki City, Kanagawa Prefecture (new bridge) - SG-3 type (only one lane on each side for both directions) - Curved pillars are used to minimize interference with the sidewalk area. *For more details, please refer to the PDF materials or feel free to contact us.
