Description
Technical field
The utility model relates to a kind of electric elements, specifically is a kind of switch cubicle.
Background technology
Switch cubicle comprises cabinet, is used for realizing line conduction or the isolating switch of partition and the earthed switch of the interior line-to-ground of control cubicle in power supply buses and the cabinet, isolating switch comprises first plug-in strip that is connected with circuit in the cabinet, first copper bar that is connected with power supply buses and is used for driving first operating axis of first plug-in strip rotation, drive the rotation of first plug-in strip by rotating first operating axis, realize conducting or the partition of circuit; Earthed switch comprises second plug-in strip of ground connection, second copper bar and second operating axis that is connected with circuit in the cabinet, drives second plug-in strip by the rotation of second operating axis equally and rotates, and is grounded the break-make of circuit.
When people need repair and maintenance, disconnect earlier isolating switch, cut off circuit in external bus and the cabinet, and then closed ground switch, make the residual charge ground connection of the interior circuit of cabinet; Yet in practical operation, because the operating axis of two switches distance is far away, people can only see the operating axis of a switch and the different operating axis of seeing second switch simultaneously, so often forget operating procedure easily, forget the disconnection isolating switch as a ground connection or disconnected isolating switch and forget ground connection, so have sizable potential safety hazard, damage the cabinet inner member easily, even cause casualties.
Summary of the invention
The technical problems to be solved in the utility model is to provide can avoid forgeing and cut off isolating switch or avoid omitting a kind of switch cubicle of ground connection.
Technical solution of the present utility model is, a kind of switch cubicle is provided, and it comprises isolating switch and earthed switch, and isolating switch comprises first plug-in strip, first copper bar and is used for driving first operating axis of first plug-in strip rotation; Earthed switch comprises second plug-in strip, second copper bar and is used for driving second operating axis of second plug-in strip rotation, it also comprises with the first interlocking hole of first lock core and the second interlocking hole with second lock core adjacent with the first interlocking hole, first lock core is through transmission mechanism and the interlock of first operating axis, and second lock core is through transmission mechanism and the interlock of second operating axis.
A kind of switch cubicle of the utility model compared with prior art has the following advantages and beneficial effect:
Because first lock core in the first interlocking hole and the interlock of first operating axis, second lock core in the second interlocking hole and the interlock of second operating axis, rotate first lock core and just can rotate first operating axis, thereby driving first plug-in strip rotates, realize disconnecting or closed isolating switch, just can rotate second operating axis and rotate second lock core, rotate thereby drive second plug-in strip, thereby disconnect or closed ground switch, and two interlocking hole sites are adjacent, whether like this, people can see two lock cores of two switches of control simultaneously clearly, namely can come into plain view and see two switches clearly and cut off, so can effectively avoid omitting operation, reduce potential safety hazard, prevent that element is impaired in the cabinet, avoid casualties.
As improvement, it also comprises first connecting rod, first connecting lever is fixedly arranged on first lock core, second connecting lever is fixedly arranged on first operating axis, the two ends of first connecting rod are hinged with first connecting lever and second connecting lever respectively, like this, clockwise or be rotated counterclockwise first lock core, drive the clockwise or counter-clockwise swing of first connecting lever, and then drive second connecting lever clockwise or counter-clockwise swing through first connecting rod, and second connecting lever of swing can drive first operating axis clockwise or be rotated counterclockwise, thus realize disconnection or the closure of isolating switch, this transmission mechanism is simple in structure, reliable in function.
As improving again, it also comprises second connecting rod, triangle connecting lever and third connecting rod, the 3rd connecting lever is fixedly arranged on second lock core, the 3rd connecting lever fixedly has first pin away from an end of second lock core, the two ends of second connecting rod are respectively equipped with vertical core and following vertical core, the first pin sliding fit is in last vertical core, rotating shaft is fixedly arranged on the cabinet, the middle-end of triangle connecting lever is rotatable to be engaged in the rotating shaft, a free end of triangle connecting lever fixedly has second pin, the second pin sliding fit is in following vertical core, the 4th connecting lever is fixedly arranged on second operating axis, the two ends of third connecting rod are hinged with another free end and the 4th connecting lever of triangle connecting lever respectively, like this, clockwise or be rotated counterclockwise second lock core, drive the clockwise or counter-clockwise swing of the 3rd connecting lever, driving second connecting rod through first pin again rises or descends, second connecting rod drives second pin and also rises or descend, make the triangle connecting lever clockwise or counter-clockwise swing, and then make third connecting rod advance or retreat, third connecting rod drives the 4th connecting lever clockwise or counter-clockwise swing, make then with fixing second operating axis of the 4th connecting lever clockwise or be rotated counterclockwise, thereby be grounded the closed of switch or disconnect.
