感震遮断システム
Document Type and Number:
Japanese Patent JP6796464
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an earthquake sensitive shutoff system capable of immediately shutting off a particular electric circuit if an earthquake sensitive relay senses an earthquake even if the earthquake sensitive relay is in cooperation with a HEMS.SOLUTION: An earthquake sensitive relay 3 includes, in addition to a pseudo ground leakage output unit 35 for implementing delayed shutoff, an external communication unit 38 for immediately outputting an earthquake detection signal upon detecting an earthquake, and also includes a communication measuring unit 4 and an earthquake sensitive communication unit 5, which relays the output signal from the external communication unit 38 and transmitting it to a HEMS apparatus 11. The earthquake sensitive communication unit 5 includes a first output unit 53 for performing shutoff operation of a second breaker 2b included in a branch breaker 2 upon receiving the earthquake detection signal.SELECTED DRAWING: Figure 1
