Summary of the invention
The object of the present invention is to provide a kind of miniaturized intelligent permanent magnetism vacuum ring main unit, make its more compact structure, volume is littler.
For realizing above-mentioned purpose; Miniaturized intelligent permanent magnetism vacuum ring main unit provided by the present invention; Comprise the vacuum switch, isolating switch and the outlet insulating base that are provided with in the cabinet; Said vacuum switch comprises vacuum interrupter, vacuum switch operating mechanism and insulated tension pole, and vacuum switch operating mechanism and insulated tension pole are in transmission connection, and the insulated tension pole lower end links to each other with the moved end of vacuum interrupter; The outlet insulating base is arranged on the quiet end of vacuum interrupter; Said isolating switch comprises bus contact, insulating contact, grounding contact, isolator operating mechanism and moving contact, and isolator operating mechanism is interlocked with the vacuum switch operating mechanism mutually, and moving contact is electrically connected with the vacuum interrupter moved end; Said isolator operating mechanism straight line is connected with the interlock insulating bar, and insulating contact is arranged on interlock insulating bar end, and the insulating contact position is corresponding with bus contact and grounding contact respectively; Be connected through flexible conductor between moving contact and the insulating contact.
In the work of the present invention, when isolating switch during at closing position, vacuum switch closes a floodgate; Major loop is connected, and this moment is because the interlocking effect of isolator operating mechanism and vacuum switch operating mechanism can not be opened isolating switch; Have only behind vacuum switch separating brake, isolating switch just can be opened, after isolating switch is opened; Insulating contact and grounding contact are connected, and can close vacuum switch this moment, and major loop is grounded through vacuum switch, insulating contact, grounding contact.During combined floodgate, isolator operating mechanism is action earlier, and then, vacuum switch can move; During separating brake, vacuum switch is action earlier, and behind the arc control device arc extinguishing, isolating switch just can move, and above-mentioned interlocking action is to guarantee safety.In the above-mentioned course of work, interlock insulating bar rectilinear motion has reduced the operating space; The volume that makes vacuum ring main unit in terms of existing technologies, further minification makes structure compact more; Reduce the cabinet materials; Reduced cost, this technical scheme makes ring main unit guarantee further to realize miniaturization under the safe prerequisite.
For improving insulation effect, be provided with the hollow insulation chamber of upper opening in the cabinet, isolator operating mechanism and vacuum switch operating mechanism are fixed on insulation chamber upside, and it is indoor that the remaining part of vacuum switch and isolating switch is arranged on insulation.The vacuum insulation chamber can according to the number of phases of bus one by one correspondence many groups are set, to reach better insulation effect.
For guaranteeing enough safe distances are arranged, the L-shaped bending in said interlock insulating bar lower end between bus contact and the moving contact.
