Abstract RU 2523717 C2

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering. Switchgear features magnetic opening system (1) including at least one armature (2), one coil (3), one yoke (4) and one yoke bushing (5). Armature (2) and yoke bushing (5) are almost coaxial, and coil (3) is located almost around armature (2) and/or yoke bushing (5). Yoke (4) is positioned around coil (3), and armature (2) is intended at least for indirect opening of switchgear opening device. The result is achieved by yoke busing (5) consisting of at least one first bent part (6) positioned inside second bent part (7).

EFFECT: better fabricability resulting in reduced production, energy and material cost.
