電機器収容キヤビネツト。 A light-controlled bidirectional thyristor is installed in a power transmission/distribution equipment housing cabinet used in an environment where it comes into contact with the public such as passers-by, and which conducts with the arc light caused by an arc short-circuit fault generated inside the cabinet and short-circuits each phase between each phase on the power supply side. In addition, the power transmission and distribution equipment housing cabinet is provided with a light-shielding mechanism that blocks incident light when the door is open, and allows arc light to enter when the door is closed, at the light incidence part of the optically controlled bidirectional thyristor.
