Abstract:
An electrical assembly comprising a housing forming a liquid tank inside thereof, dielectric liquid in the liquid tank, at least one fuse, and a blown fuse indication system. Each of the fuses is immersed in the dielectric liquid, and is provided with a striker pin. The blown fuse indication system is adapted to indicate a blowout of any one of the fuses by an indication signal. The blown fuse indication system comprises a first indication member and a second indication member. The first indication member is movable by the striker pins. The second indication member is immovably connected to the housing, and adapted to generate the indication signal as a response to relative movement between the first indication member and the second indication member.
