Three bus contacts of three epoxy-pouring full-insulation solid isolating switch of the present utility model are connected AC power A, B, C three phase isolated bus (also available tangible cable end is pegged graft) respectively successively.With one is that example is described below mutually:
The house lead in source current arrives insulating contact by the bus contact through the switching busbar, if this moment, epoxy-pouring full-insulation solid isolating switch was in "on" position, electric current flow to middle contact from the bus contact through isolating moving contact, again from middle contact through the lead that is flexible coupling to external electric equipment, finally form the galvanic circle.
When the needs epoxy-pouring full-insulation solid isolating switch carries out separating brake (ground connection), at this moment controlled operating mechanism driven gear rotates, the linkage leading screw rotates, thereby make screw on leading screw, rely on screw thread to move backward, driving moving contact makes the front end of moving contact leave insulating contact, reach the disjunction distance, and finish the separating brake process.
The utlity model has combined floodgate, separating brake and three kinds of states of ground connection, ground state designs for this isolating switch is in a safe condition, ground state is: moving contact rotates and moves backward always along with leading screw, the interior watch chain fingertip of the front end of final moving contact and middle contact contacts, watch chain fingertip in the rear end of moving contact and the grounding contact contacts, and finishes the ground connection process.
Characteristics of the present utility model:
1, the utility model is to adopt poured with epoxy resin all insulation equipment, and the surrounding environment influence that is not subjected in service is not subjected to condensation and filthy influence.
2, complete equipment has high electrical safety performance, and switch cut-offs and do not exist during accident such as the electric current that is short-circuited the possibility of blast.
3, insulated part all adopts good epoxy resin of hydrophobicity and silicon rubber manufacturing.Do not have the danger that gas and liquid are revealed.Can not pollute to environment.
4, the utility model isolating switch adopts the epoxy sealing cavity, and sealing is not influenced by outside air.
5, the utlity model has combined floodgate, separating brake and three kinds of states of ground connection.
6, the grounding contact of the utility model isolating switch, middle contact, isolate lift one's head, the bus contact is positioned on the same isolation body, one-time cast-forming fully guarantees the proper alignment of its three contact, makes reliable transmission, dynamic/static contact contact reliable.
