Title:
電子式回路遮断器
Document Type and Number:
Japanese Patent JP6658969
Kind Code:
B2
Abstract:
An electronic circuit breaker includes: a make and break contact 2 that makes and breaks a conducting path 1; a current sensor 3 that detects a current through the conducing path 1; a first microcomputer 10 that receives an output signal of the current sensor 3 as an input and outputs an instantaneous tripping signal; a second microcomputer 20 that acquires information on the current flowing through the conducting path 1 from the first microcomputer 10 and outputs a time-limited tripping signal; and a tripping device 8 that releases the make and break contact 2 based on the instantaneous tripping signal and the time-limited tripping signal. The first microcomputer 10 notifies the second microcomputer 20 that the first microcomputer has been restarted by a first port output 106a, and the second microcomputer 20 notifies the first microcomputer 10 that the second microcomputer has been restarted by a parallel communication 206b.
