FIELD: electricity.
SUBSTANCE: gas relay (1) contains supporting frame (2) which contacts oil; actuating facilities (3) connected to frame (2); switching devices (4) functionally connected to facilities (3) and meant for blocking or unblocking of fault-signalling network and/or of tripping scheme of electrical equipment; adjusting gate (5) of oil flow connected to frame (2) and designed with possibility of impact of oil flow on it, it has the first position in which it blocks tripping scheme and the second position to which it sets if oil flow rate exceeds certain threshold value and in which it unblocks tripping scheme. Relay (1) contains counteracting devices connected to frame (2) and gate (5) to maintain the gate in the first position.
EFFECT: possibility of rising of threshold of action of transformer tripping scheme under high oil flow due to rising of gate action threshold.
