Title:
CABLE WAY ABNORMALITY DETECTOR, AND SWITCH INCLUDING THE SAME
Document Type and Number:
Japanese Patent JP2018101549
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cable way abnormality detector capable of reducing heat generation in a power supply circuit section, and to provide a switch including the same.SOLUTION: A power supply circuit section 20 includes a power storage section 30, a switch 40, and a voltage detector 50. The power storage section 30 is charged with a DC voltage inputted to an input terminal 21 from a detection object cable way of an abnormality detector 60. The voltage charging the power storage section 30 is outputted, as a power supply voltage V1, to the abnormality detector 60. The switch 40 switches the state of the power storage section 30 to any one of the state of charge where a charging current flows from the detection object cable way to the power storage section 30 via the input terminal 21, or the charge stop state where the charging current does not flow to the power storage section 30. The voltage detector 50 detects the power supply voltage V1 outputted from the power storage section 30 to the abnormality detector 60. The switch 40 is controlled according to the detection results from the voltage detector 50.SELECTED DRAWING: Figure 1
