RELAY ON REED RELAYS Russian patent published in 2019 - IPC H01H57/00 

FIELD: electric power engineering.

SUBSTANCE: invention relates to electric power industry, namely to relay protection equipment, and can be used for protection of electric installations against short circuits. In relay comprising two reed relays with one control coil with n turns, one with closing and the other with opening contacts, according to invention reed relays are installed mutually perpendicular relative to each other, and their contacts are connected in series, at that, on reed switch with closing contact, m turns of n turns of control winding are wound, and on turns with opening contact there are wound n-m turns, at that ratio of turns on sealed terminal with opening contact and turns on sealed terminal with closing contact is equal to not more than 1.5.

EFFECT: prevention of excessive actuation of relays from interference in circuit of its control coil.
