Title:
PLUG-IN CONNECTION UNIT
Document Type and Number:
Japanese Patent JP2019134681
Kind Code:
A
Abstract:
To provide a plug-in connection unit having a function for operating a circuit breaker, even if a normally operable wiring state is not ensured, in an outlet with which the plug-in connection unit is connected.SOLUTION: A plug-in connection unit used by connecting with an outlet circuit having a voltage electrode (L pole), a neutral electrode (N pole), and a ground electrode (E pole) includes a plug blade being plugged in corresponding to the plug receptacle of each pole provided in the outlet, a power supply circuit connected electrically with the plug blade and acquiring a drive power supply, a current generation unit for feeding a current between the neutral electrode and the ground electrode in the outlet circuit, a voltage measurement unit for measuring the voltage between the neutral electrode and the ground electrode, and a grounding resistance calculation unit for calculating the grounding resistance from the current generated in the current generation unit and the voltage measured in the voltage measurement unit.SELECTED DRAWING: Figure 1
