設備用地絡保護装置。[Claims for Utility Model Registration] 1. In a solar cell power generation facility that is divided into a plurality of power generation blocks and connected in parallel to a pair of positive and negative common busbars, one of the two busbars is grounded. Ground fault detection is installed at the connection between both buses and each generating block to detect the ground fault current flowing through the connection in the event of a ground fault, and to selectively disconnect the generating block that has caused the ground fault from the bus. A ground fault protection device for solar cell power generation equipment characterized by being equipped with a breakout switch. 2 Utility Model Registration Claims In the ground fault protection device for solar power generation equipment as set forth in claim 1, the ground fault detection and disconnector are integrated with the connection line, and the connection line can be connected by being inserted into the bus bar and the power generation block. A ground fault protection device for solar cell power generation equipment, characterized in that it is configured as a plug-in unit. 3. In the earth fault protection device for solar cell power generation equipment as set forth in claim 1 of the utility model registration claim, the power generation block is a roof-mounted block, the bus bar is surrounded by a channel-shaped protective cover, and the connecting wire is connected to the channel. A ground fault protection device for solar cell power generation equipment, characterized by having a curved portion that can be connected to a busbar by climbing over the legs.
