Abstract

A Buchholz relay (1) for comprising a support frame (2) in contact with the oil, drive means (3) coupled to the support frame (2), switching means (4), operatively connected with the drive means (3) and suitable for an alarm circuit and/or a shutdown circuit of the electrical equipment, a regulation valve (5) of the oil flow, coupled to the support frame (2), suitable to be affected by the oil flow in order to define a first position in which it disables the shutdown circuit and a second position in which, if the oil discharge exceeds a certain threshold, it enables the shutdown circuit. The Buchholz relay (1) also includes biasing means associated with the support frame (2) and with the valve (5) to keep the latter in the first position.
