Claims

[Scope of Claim for Utility Model Registration] (1) A test terminal cover that can be opened and closed to close the insulation barrier of an automatically connecting type grounding device that is inserted into a closed switchboard and has a testing function for the withstanding voltage or current transformer of the system. , a lock plate attached to the test terminal cover, an opening formed in the test terminal cover, and a grounding device located below the test terminal cover are attached so as to be movable up and down, so that the test terminal cover is opened. A position lock rod whose upward movement is sometimes regulated by the lock plate, and whose upper end passes through the opening when the test terminal cover is closed, and whose upward movement is allowed to rise; and a position lock rod which is provided on the closed switchboard side and is grounded. When inserting the device into a closed switchboard, when the position lock rod is lowered, it engages the lower end of the position lock rod to restrict the insertion of the earthing device, and when the position lock rod is raised and the earthing device is in the middle of insertion, the position lock is engaged. A grounding device characterized by comprising a lock plate on the closed switchboard side that restricts the descent of the rod and allows the position lock rod to fall when the earthing device is inserted and connected, allowing the test terminal cover to be opened. Equipment interlock mechanism. (2) The earthing device interface set forth in claim (1) of claim 1, wherein the lock plate has a fan shape, and its arc portion restricts the upward movement of the position lock bar. Lock mechanism.
