のメガリング機構。 In a megger ring mechanism that makes it possible to measure the insulation resistance of a load circuit consisting of a load cable, a motor, etc. in a power distribution board, a shutter device is driven that opens and closes the front surface of a connecting bushing of a draw-out type circuit breaker in the power distribution board in conjunction with the circuit breaker. The lever is rotatably supported by a support member fixed to the inside of the connection bushing mounting partition via an insulator, so that it contacts the fixed contact of the connection bushing when the circuit breaker is pulled out, and opens when it is pulled in. A movable contact for the ground circuit is connected via a lever passing through the partition wall, and a torsion spring that presses the movable contact for the ground circuit in the opening direction when the movable contact for the ground circuit is opened,
The mega ring mechanism of the power distribution board is characterized by being attached to its rotating shaft.
