Detailed description of the invention
Technical spirit of the present utility model and beneficial effect can be fully understood in order to make the public; applicant will describe in detail detailed description of the invention of the present utility model below by reference to the accompanying drawings; but applicant is not the restriction to technical scheme to the description of embodiment, any changing in the form rather than substance according to the utility model design all should be considered as protection domain of the present utility model.
Refer to Fig. 1 and Fig. 2, the utility model relates to a kind of vacuum circuit breaker, this vacuum circuit breaker has vacuum bubbles 1, insulated tension pole 2, connecting lever 3, operating mechanism 4 and sensor 5, and wherein vacuum bubbles 1, connecting lever 3, operating mechanism 4 and sensor 5 are installed on framework 10.Insulated tension pole 2 is between vacuum bubbles 1 and connecting lever 3, the swinging end that one end connects the moved end of vacuum bubbles 1, the other end of insulated tension pole 2 connects connecting lever 3 of this insulated tension pole 2, another swinging end attended operation mechanism 4 of connecting lever 3, connecting lever 3 rotates and is arranged on described framework 10.Thus operating mechanism 4 can drive connecting lever 3 to swing, and then drive insulated tension pole 2 to move, the contact system in final drive vacuum bubbles 1 carries out conjunction point action.This operating mechanism 4 also includes energy-stored spring 41, and described energy-stored spring 41 provides energy for the action of operating mechanism 4.This operating mechanism 4 is specifically as follows spring operating mechanism or permanent-magnet operating mechanism, to adapt to different client's needs.
Sensor 5 described in the utility model be arranged on be close to operating mechanism 4 side framework 10 on, and to be connected with described connecting lever 3.Thus after connecting lever 3 swings, sensor 5 can monitor the displacement of connecting lever 3, and outwards transmits.Preferably, described sensor 5 be arranged in three dividing plates 101 on the framework 10 of vacuum circuit breaker wherein at least one, three dividing plates 101 mark off four independently spaces on framework 10, thus make sensor 5 be more suitable for being connected with nearer connecting lever 3.Certainly, if dividing plate only has a requirement that also can meet this programme.Preferably, described sensor 5 is arranged on the below of dividing plate 101 short transverse, corresponding with the position of connecting lever 3.When dividing plate 101 is multiple, sensor 5 can be arranged on different dividing plates 101, makes the installation site of sensor 5 convertible, adapts to vacuum circuit breaker internal space requirements.The quantity of sensor installation 5 depends on actual needs, and installing one under normal circumstances can meet actual needs.
