Abstract (en)
[origin: EP0945951A2] A gas-accumulation Buchholz relay, which comprises, to be immersed in an oil bath, a supporting frame (23) for magnetic switches (27) for closing circuits and at least one movable device (28,29) of the float type for actuating the switches. The relay is characterized in that the float (30) is of the lever type with a rotation axis which is fixed to the frame (23) and is operatively connected to a magnet holder which acts as a counterweight. The float (30) is articulated in its rotation with respect to the magnet holder through a given angle. <IMAGE>
