Description
Technical field
The utility model belongs to switch electrical control gear field, particularly a kind of ring main unit.
Background technology
In the prior art, a kind of small size vacuum ring main unit is arranged, its patent No. is ZL200720036344.3, its structure mainly comprises vacuum switch, isolating switch, circular main bus bar and the outlet insulating base that is provided with in the cabinet, described vacuum switch is made of vacuum interrupter, vacuum switch operating mechanism and insulated tension pole, vacuum switch operating mechanism and insulated tension pole interlock, the insulated tension pole lower end links to each other with the moved end of vacuum interrupter; Described isolating switch is made of bus contact, insulating contact, insulating contact, grounding contact, isolator operating mechanism and moving contact, the insulating contact upper end links to each other with isolator operating mechanism, the insulating contact lower end links to each other with the insulating contact middle part, insulating contact one end and moving contact are hinged, the insulating contact other end is corresponding with bus contact and grounding contact respectively, and the bus contact is connected with circular main bus bar; Isolator operating mechanism is interlocked mutually with the vacuum switch operating mechanism, 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, it is indoor that the remaining part of vacuum switch and isolating switch all is arranged on insulation, the moving contact of described isolating switch is fixed on the insulation indoor, and moving contact and vacuum interrupter moved end indoorly are flexible coupling through electric conducting material insulating; The outlet insulating base stretches into insulation and indoorly links to each other with the quiet end of vacuum interrupter lower end.When this device uses, some insulation chamber can be set according to the number of phases of circular main bus bar, when isolating switch during at closing position, vacuum switch closes a floodgate, major loop is connected, this moment is because the interlocking effect of isolator operating mechanism and vacuum switch operating mechanism, isolating switch can not be opened, have only behind vacuum switch separating brake, isolating switch just can be opened, and after isolating switch was opened, insulating contact and grounding contact were connected, can close vacuum switch this moment, and major loop is grounded through outlet insulating base, vacuum switch, insulating contact, grounding contact.In the above-mentioned course of work, the insulation chamber is isolated with the charged workpiece of each corresponding isolating switch and vacuum switch, improved the class of insulation, because what isolator operating mechanism adopted is that the revolution mode is separated insulating contact and bus contact, need the space of certain gyration, cause the volume of ring main unit bigger, especially for small-sized ring main unit, the leeway of further reduced volume is arranged still.
The utility model content
The purpose of this utility model is to provide a kind of miniaturized intelligent vacuum ring main unit, makes its more compact structure, and volume is littler.
For achieving the above object, miniaturized intelligent vacuum ring main unit provided by the utility model, comprise the vacuum switch, isolating switch and the outlet insulating base that are provided with in the cabinet, described vacuum switch comprises vacuum interrupter, vacuum switch operating mechanism and insulated tension pole, 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; Described isolating switch comprises bus contact, insulating contact, grounding contact, isolator operating mechanism and moving contact, and isolator operating mechanism is interlocked mutually with the vacuum switch operating mechanism, and moving contact is electrically connected with the vacuum interrupter moved end; Described 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 utility model work, when isolating switch during at closing position, vacuum switch closes a floodgate, and major loop is connected, this moment is because the interlocking effect of isolator operating mechanism and vacuum switch operating mechanism, isolating switch can not be opened, 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, 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 described interlock insulating bar lower end between bus contact and the moving contact.
