FIELD: fire dangerous industrial plants.
SUBSTANCE: plug socket can be used in industrial plants when automatic disconnection of electric circuits is required if environmental temperature increases till specified limit. Plug socket of electric connection has case, contact group, safety fuse, resilient member intended for disconnecting plug socket from plug, and protection casing with holes mounted onto case. Resilient member and safety fuses are disposed between case and protection casing. Safety fuse doesn't belong to electric circuit and it is made in form of insertion. Resilient member is fixed in compressed position by safety fuse which has insertion made of material with temperature of melting being equal to 85-90°C. Heat-insulating gaskets are mounted among insertion, case and casing. Casing is made of material with heat conductance being equal or higher than 100-160-kcal/m·hour°C. Plug socket is provided with locker, which provides irreversibility of disconnection of electric circuits.
EFFECT: improved precision of operation induced by influence of environment; provision of irreversible disconnection.
