PURPOSE: An independent power generation glass bulb sensor operation part is provided to operate an electric automatic extinguishing device by generating a current in a circular coil of an electromotive force generation part according to the movement of a permanent magnet of a moving core. CONSTITUTION: An independent power generation operation apparatus(100) comprises a moving core inducing electromotive force and an electromotive force generation part(44) generating electromotive force according to the movement of the moving core. The moving core comprises a head(82), a rod connected to the head and a concave part(84) connecting the head and the rod. The concave part forms a concave area by being narrower than the rod. The moving core comprises a permanent magnet(88) connected to the end of the rod. The head, the concave part and the rod of the moving core are inserted into a moving core insertion tube(12). |
