Structures for mounting reed switches near the busbars of electrical installations with remote control of their position.

It is noted that in relay protection resource savings can be achieved by replacing current transformers with ferromagnetic cores with miniature current sensors, such as inductance coils, reed switches, etc. It is emphasized that special designs are required for their mounting near the busbars. Models of two such designs for mounting reed switches are proposed. The first differs from the known ones by the presence of a single stepper motor connected to a microcontroller, which makes it possible to remotely move the reed switch in the horizontal plane, and the second – two electric motors, which allows you to move the reed switches in the vertical plane. At the same time, the microcontroller is located in the relay compartment of the cell of the complete switchgear, which ensures the safety of service personnel. The method of regulating the position of reed switches in space using the proposed designs is described. [ABSTRACT FROM AUTHOR]
