DEVICE FOR SECURING REED SWITCHES IN CELLS OF FACTORY-ASSEMBLED SWITCH-GEARS Russian patent published in 2018 - IPC G01R33/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, can be used for current protection. Such technical result is achieved by the fact that the structure for fastening the reed switches in the cells of factory-assembled switch-gears with three current-carrying buses contains a time-setting unit, an actuating unit, a first plate rigidly fixed to the legs of the withdrawable carriage frame. In the first plate there are longitudinal through holes in which three blocks are fixed, composed of three boxes, stacked on top of each other. At the bottom of each box there are the first and second terminal blocks, the time-setting unit and the second plate, along the side walls of which there are through holes in which 3–6 reed switches are fixed in parallel to each other. Further, the contacts of the reed switches are connected to the input of the first terminal block, whose output is connected to the input of the time-setting unit, whose output is connected to the input of the second terminal block connected to the input of the executive unit.

EFFECT: technical result is the possibility of moving the reed switches in relation to the two directions and their protection from external influences.
