ABSTRACT:
A relay unit associated with a fluid cooled transformer apparatus. The relay utilizes an hydraulic bellows circuit system to sense internal pressure changes developing in a tank member of the transformer apparatus; and it responds to a sudden rise in the pressure to operate an alarm switch. The system includes a group of three bellows, one of which reacts to pressure changes in the tank; and the other two of which respond according to the reaction of the first in controlling operation of the switch. A pivoted bracket and supporting spring arrangement associated with the bellows serves to control operation of the switch and to restrain it from being operated by shocks and the like attendant upon seismic conditions.
