差込接続ユニット
Document Type and Number:
Japanese Patent JP6605058
Kind Code:
B2
Abstract:
To provide an insertion type connection unit having a function for making a circuit breaker operate even if a normally-operable wiring state is not secured, in a receptacle to which the insertion type connection unit is connected.SOLUTION: An insertion type connection unit includes: a plug blade inserted in response to a plug receiver at each pole provided in a receptacle; a power supply circuit electrically connected to the plug blade to obtain driving power; a current generation part for flowing an electric current between a neutral pole and a grounding pole in a receptacle circuit; a voltage measurement part for measuring a voltage between the neutral pole and the grounding pole; and a grounding resistance calculation part for calculating a grounding resistance from the electric current generated from the current generation part and the voltage measured by the voltage measurement part. Based on a level of the grounding resistance obtained by the grounding resistance calculation part, the level of the electric current output from the current generation part is changed and output.SELECTED DRAWING: Figure 1
