Title:
SEISMOSCOPIC INTERRUPTION SYSTEM
Document Type and Number:
Japanese Patent JP2018068098
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a seismoscopic interruption system for making it easy to perform setting and grasp an operation state on a seismoscopic relay installed in a power distribution board.SOLUTION: A seismoscopic relay 3 for making a trunk breaker 1 perform interruption operation after the lapse of a prescribed time after occurrence of an earthquake includes: a MCU 39 for making an earthquake detection signal be output immediately when sensing an earthquake having seismic intensity equal to or higher than predetermined seismic intensity; and an external communication section 38 for making it possible to set a seismic intensity threshold and delay time from the outside of a power distribution board. On the other hand, a display unit 4 for displaying information based on an earthquake detection signal when the seismoscopic relay 3 outputs the earthquake detection signal is provided outside the power distribution board B; a seismoscopic communication unit 5 for managing communication between the display unit 4 and seismoscopic relay 3 is included in the power distribution board B. When setting operation for the seismoscopic relay 3's seismic intensity threshold and delay time is performed via the display unit 4, setting for the seismoscopic relay 3 is performed by relay of the seismoscopic communication unit 5.SELECTED DRAWING: Figure 1
