Embodiment
Further the structure of the utility model operation power supply carriage is described below in conjunction with accompanying drawing.
Fig. 1 is that the utility model operation power supply carriage places the indoor structural representation of control cubicle operating power, and Fig. 2 hauls out outdoor operating power structural representation with operation power supply carriage.By Fig. 1, shown in Figure 2, the utility model operation power supply carriage comprises dolly support 9, place the chassis car 10 under the dolly support 9, place the high-tension fuse 3 of 6 winding sides of voltage transformer, with the insulation booth 4 that high-tension fuse 3 is connected mutually, be connected in the high pressure supporting insulator 5 between insulation booth 4 and the dolly support 9.High pressure supporting insulator 5 plays the supports insulative box on the one hand, also plays insulating effect simultaneously.With the high-tension insulating bushing 2 that the other end of insulation booth 4 is connected, a moving contact 1 that places the fixed contact 14 with on placing cabinet 12 (control cubicle) of high-tension insulating bushing 2 front ends to match.Place the valve riser 11 below moving contact of dolly support 9 front ends.Socket 7 is moved in the aviation that is seated on dolly support 9 tops that is connected on voltage transformer 6 secondary winding.That matches with the moving socket 7 of aviation places aviation static socket 8 on the cabinet 12.Be equipped with electrical interlock 15 (direct connection relational shows on the figure) between being connected of work loop in control cubicle in aviation static socket 8 and the control cubicle.Electrical interlock 15 is to place on cabinet 12 and the operating power chamber door 1201.Because the connected sum that the closure of electrical interlock 15 is being controlled work loop in aviation static socket 8 and the control cubicle disconnects, the connected sum of just controlling the loop of working in voltage transformer 6 secondary winding and the control cubicle disconnects.Again because electrical interlock 15 is to place on cabinet 12 and the operating power chamber door 1201, the closure of electrical interlock 15 is controlled by shutting and opening of operating power chamber door 1201, so voltage transformer 6 secondary winding are communicated with and disconnection with the interior work of control cubicle loop, also just are controlled by shutting and opening of operating power chamber door 1201.
Fig. 3 is the structural representation of the chassis car 10 of operation power supply carriage, described chassis car 10 is fixed in the bottom of operation power supply carriage, by shown in Figure 3, chassis car 10 comprises base plate 1004, the roller of installing on four jiaos below the base plate 1,004 1001, place the trap 1003 on base plate 1004 sides, place pass trap 1003 on the centre position above the base plate 1004 shake screw mandrel 1005, be contained in and expose outer the shaking of trap 1003 and shake handle 1002 on screw mandrel 1005 tops.In the present embodiment, shake handle 1002 and adopt universal crank handle device.
Fig. 4-1, Fig. 4 the-the 2nd, the concrete structure of electrical interlock 15 and the state that closes and open thereof.Shown in Fig. 4-1, Fig. 4-2, electrical interlock 15 comprises the oily column 1502 that places on the cabinet 12, places the travel switch 1503 of oily column 1502 centres; Place the impact block 1504 on the operating power chamber door 1201.In order to prevent that impact block 1504 from falling to going up dust, is equipped with dust guard 1505 on the next door of impact block 1504.Contain interior contacts 1501 at travel switch 1503.When operating power chamber door 1201 is shut, impact block 1504 impact stroke switch 1503, make in its interior contacts 1501 1., 3. junction closure (shown in Fig. 4-1), then make to be inserted in and be connected in the aviation static socket 8 in the moving socket of aviation and the interior work circuit communication of control cubicle, the operating power of promptly closing on the voltage transformer 6; When operating power chamber door 1201 is opened, in travel switch 1503 interior contacts 1501 1., 3. contact disconnects (shown in Fig. 4-2), i.e. rupturing operation power supply.
As above-mentioned structure, operation power supply carriage push operation power supply dolly is indoor, and this moment, operation power supply carriage was in isolation/test position.Shake handle (universal crank handle device) 1002, the screw mandrel 1005 that shakes in the operation power supply carriage chassis car 10 moves thereupon, and the power supply dolly enters the service position operated-slowly.Valve riser 11 on the operation power supply carriage backs down retaining on the cabinet 12 at the valve cover plate 13 of fixed contact 14 front ends at this moment, fixed contact 14 contacts with a moving contact 1 on the operation power supply carriage, then main circuit power is (in the present embodiment, the voltage of main circuit power is 10KV) through its high-tension fuse 3, be transported to voltage transformer 6 interior windings, to the secondary winding (the voltage transformer here is equivalent to transformer) of voltage transformer 6, therefore the voltage through the output of voltage transformer 6 secondary winding becomes 220V again.Shut operating power chamber door 1201, impact block 1504 on the described operating power chamber door 1201 contacts with the travel switch 1503 of oily column 1502 on being arranged in cabinet 12, make in its interior contacts 1501 contact 1., 3. closed, the 220V power supply just passes through the closure of travel switch 1503, be transported in the work loop through the moving socket 7 of aviation, aviation static socket 8, for control cubicle provides working power.When switchgear operation is broken down (as the improper tripping operation of combined electrical apparatus of control cubicle etc.), under emergency, opening operation power supply room door 1201, this moment, impact block 1504 separated with travel switch 1503,1., 3. travel switch 1503 interior contacts disconnect, and operating power is cut off.Utilization is shaken handle 1002 operation power supply carriage is shaken out to isolation/test position, fixed contact 14 in the cabinet 12 separates with a moving contact 1 on the operation power supply carriage, valve cover plate 13 on fixed contact 14 also closes thereupon, main circuit power is also intercepted, and can carry out the safety inspection operation to operation power supply carriage.
