Title:
INSPECTION PLUG
Document Type and Number:
Japanese Patent JP2014202671
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce complexity and erroneous wire connection of an inspection of a relay system.SOLUTION: The inspection plug includes: an electrode body connected to a first current transformer when an inspection plug is inserted to a main body; a variable resistor connected to the first current transformer when the inspection plug is inserted to the main body and connected to the electrode body so as to generate a pseudo current that simulates a current indicating an occurrence of an accident; a projection piece projecting from the inspection plug so as to prohibit the inspection plug from being inserted to the main body before the inspection plug is inserted to the main body and prohibit the inspection plug from being taken out from the main body while the inspection plug is inserted to the main body; a knob for causing a resistance value of the variable resistor to become a value which makes the value of the pseudo current become a predetermined value or more when the projection piece is projected, and causing the resistance value of the variable resistor to become the value which makes the value of the pseudo current become less than the predetermined value when the projection piece is retracted, and projecting and retracting the projection piece and adjusting the resistance value of the variable resistor.
