Document Type and Number:
Japanese Patent JP6715215
Kind Code:
B2
Abstract:
To provide a high frequency separation fuse which is not blown off by a high frequency lightning surge current, and is blown off reliably by a low frequency abnormal current.SOLUTION: A high frequency separation fuse 1 which separates a high frequency current, and is blown off by a low frequency current includes an abnormal current blowout part 1d capable of feeding a low frequency current from the input port 1a side to the output port 1b side, and an external housing 1c placed to cover the abnormal current blowout part 1d, and capable of feeding the high frequency current and the low frequency current from the input port 1a side to the output port 1b side. When the low frequency current flowing through the abnormal current blowout part 1d is an abnormal current exceeding a predetermined current amount, the abnormal current blowout part 1d is blown off to block the abnormal current flow from the input port 1a to the output port 1b side.SELECTED DRAWING: Figure 1
