Abstract:
This invention concerns a device for an outdoor switching apparatus of an electrical power line, the switching apparatus being enclosed within a case. The device includes a wall made of electrically conductive material capable of blocking sun rays. The device also includes a fastening assembly for fastening the wall with respect to the case in a position for blocking, at least partially, sun rays from hitting the case during day time. The fastening assembly has at least one spacer made of insulating material for spacing the wall with respect to the case, thus delimiting an air gap between the wall and the case. The device also includes at least one electrical connector for electrically connecting the wall to circuitry of the switching apparatus, located inside the case, for powering and voltage monitoring.
Abstract:
There is provided a contact switching device which has high productivity and in which operation characteristics hardly vary. The contact switching device includes an electromagnetic unit (60), a holder (35), a movable shaft (43), a movable yoke (48), a movable contact piece (49) having movable contacts (49a) at both ends, fixed contacts (33a), and a fixed yoke (51). At the time of excitation of the electromagnetic unit (60), the movable shaft (43) moves to the holder (35) side along a direction of an axis center. A magnetic circuit is formed of the fixed yoke (51) and the movable yoke (48) due to a magnetic field generated by a current that flows into the movable contact piece (49a) as a result of the movable contacts (49) coming into contact with the fixed contacts (33a). The movable yoke (48) is then attracted to the fixed yoke (51).
