Title:
ELECTRICAL PATH ANOMALY DETECTION DEVICE AND SWITCH EQUIPPED THEREWITH
Document Type and Number:
WIPO Patent Application WO/2018/116860
Kind Code:
A1
Abstract:
The objective of the present invention is to reduce the generation of heat from a power source circuit section. The power source circuit section (20) comprises a power storage unit (30), switch units (40), a voltage detection unit (50), and a control unit (50). The power storage unit (30) is charged by a direct current voltage inputted into an input terminal unit (21) from an electrical path where detection is carried out by an anomaly detection section (60). The voltage charged into the power storage unit (30) is outputted as a power source voltage (V1) to the anomaly detection section (60). The switch units (40) switch the state of the power storage unit (30) between either a charging state and a charging stopped state. The voltage detection unit (50) detects the power source voltage (V1). The control unit (50) controls the switch units (40) according to the detection result from the voltage detection unit (50).
