longer acts on cam disc 20 with its cam disc 19, make by the effect of the spring force of contact spring 13, the arc extinguishing contact system 9 of closed auxiliary current path again, and between cutter opposite end 5 and cutter opposite end 6 and fixed contact 2 and 3 and sliding contact 15 and 16 between there is enough distances, to meet the dielectric separation condition of switching device and medium voltage switchgear equipment.
Therefore in other words, between the primary importance of on-state of load separating switch 1 of Fig. 1 and the second place of the formed isolating partition with load separating switch 1 of Fig. 6 by rotary support 7 and therefore rotatablely move and pass through the anglec of rotation region of rotatable motion contact 4 in the 4 interior introducings of rotatable motion contact, make first to realize the commutation from primary current path to auxiliary current path of the alternating current that flows through switching device, and at arc extinction and be further rotated when motion, when reaching the second place of Fig. 6, realize the formation of isolating partition.
The connection process of load separating switch 1 realizes in the following way, further introduce rotatablely moving and further rotate rotatable motion contact 4 in identical direction as the illustrated load separating switch 1 in separation point position in Fig. 6, until the second last cutter opposite end 6 is connected with the first fixed contact 2 conductions and the first cutter opposite end 5 is connected with the second fixed contact 3 conductions, before wherein connecting electric arc, light, this is arranged in to fill for load separating switch 1 and does not have problems with the situation in the container of dielectric, and especially realized the vacuum switch tube 10 of constructing at an easy rate arc extinguishing contact system 9, because described vacuum switch tube 10 do not participate in connection process and therefore for its resistance to connection without proposing specific (special) requirements.In addition, in the layout around 360 ° of rotatable motion contacts 4, auxiliary current path can be made by cheap material, for example, by steel, stainless steel or aluminium, make, because guide current in short-term only on auxiliary current path, and especially in auxiliary current path, there is not short circuit current.
Fig. 7 shows threephase switch device 1, wherein each 26,27 or 28 formation of the embodiment according to Fig. 1 to Fig. 6 mutually, obvious housing 24 wherein, and wherein independent phase 26,27 and 28 interconnects by Connection Element 29, make by introducing rotatablely moving to be incorporated into when rotary support 7 is interior have been realized for all phases and operating of driver not illustrated in FIG..
Fig. 8 shows the load separating switch 1 in its second place with formed isolating partition, as explained in detail with reference to figure 6, wherein in Fig. 8, in the second fixed contact 3, provide ground joint 30, described ground joint 30 is connected with ground connection motion contact 31 conductions in Fig. 8, and the described ground connection contact 31 of moving is rotatably mounted and be connected with earth potential on the point of rotation 32.
In Fig. 9, illustrate dividually ground connection motion contact 31 with ground joint 30, make the ground connection in the cable joint region that has formed switching device in Fig. 8 in illustrated position of ground connection motion contact 31, and in Fig. 9 in illustrated position switching device in normal operation mode.
The earthed switch of structure individually of the ground connection motion contact 31 driving by the driver (not illustrated in FIG.) with by independent, the position of the switch of load separating switch 1 and earthed switch is combination mutually changeably, therefore for example also in the failure condition in container, when primary current path is closed and therefore, even when busbar is connected, also can and so effectively prevent pressure initiation when the container indigenous fault electric arc by whole current path ground connection.
