FIELD: electricity.
SUBSTANCE: invention pertains to a single-pole disconnecting device. The single-pole disconnecting device is suggested with the following composition: contacting bridge (22) with at least one fixed contact (41, 51) operated together with the contact bridge as well as a tuner bar (26) having a cross bore (21) wherein the contacting bridge is mounted and protruded from each side of the turner bar (26), at that the bar (26) is inserted between two side plates (14) of the disconnecting device. The contacting bridge comprises two seal flanges (27) placed between radial surfaces of the turner bar (26) and side plates (14) respectively. At least one arc blow-out chamber (24) is communicated to open space of the contacting bridge (22). The turner bar (26) comprises at least one channel (29) connected to transversal intake opening (21).
EFFECT: development of the disconnecting device with turner bar and effective sealing facility.
