FIELD: physics.SUBSTANCE: optical fuse for body of revolution comprises a housing, in the cavity of which there is a photodiode with an electronic board and a movable spring-loaded element. The fuse further includes an optical receiver with an electronic board. The photodiode and the optical receiver are located in a channel, the axis of which is parallel to the axis of revolution of the housing. The movable spring-loaded element is in form of a sphere, wherein the movable spring-loaded element is installed in a channel, the axis of which is perpendicular to the axis of the channel of the photodiode and the optical receiver and crosses said axis, and the sphere, at its outermost position, closes the channel of the photodiode and the optical receiver under the action of the spring.EFFECT: high reliability of the fuse.2 dwg |
