Abstract
An interlocking device of a ground switch operating mechanism of a central-positioned high-voltage switch cabinet comprises an operating rod and a support, wherein the operating rod is provided with a raised head; the support is internally and flexibly connected with a lock sleeve below which a groove is arranged; the raised head extends into the groove of the lock sleeve; the right end of the support is provided with a shaft hole in which a latching shaft with a pressure spring is inserted; the latching shaft is provided with a pin; the pressure spring is positioned between a right end face pin hole of the support and the pin on the latching shaft; and the other end of the latching shaft extends out of a rear door frame. The interlocking device is improved from the original interlocking device by enhancement of reverse interlocking with the rear door so that the ground switch can only be operated after the rear door (a sealing plate) is closed first. The structure is simple, the reliability is strong and the error prevention performance is greatly strengthened.
Description
Technical field
The utility model relates to a kind of switch cubicle interlock, relates in particular to a kind of earthed switch operating mechanism interlock of middle high-tension switch cabinet.
Background technology
" interlocking " of high-tension switch cabinet is to guarantee the power network safe operation, guarantee equipment and personal safety, prevent the important measures of misoperation.The earthed switch operating mechanism of existing middle high-tension switch cabinet does not have the reverse interlocking with the back door, and just earthed switch is opened back door (being shrouding) after closing a floodgate, but still operational grounding switch, the danger that can cause the staff to get an electric shock like this of former interlocking.
The utility model content
Technical problem to be solved in the utility model is to overcome the prior art defective, and a kind of middle high-tension switch cabinet earthed switch operating mechanism interlock is provided, and when guaranteeing that the back door is opened, earthed switch can't be operated.
Technical solution adopted in the utility model is: a kind of middle high-tension switch cabinet earthed switch operating mechanism interlock, comprise action bars, bearing, it is characterized in that action bars is provided with plush copper, be connected with lock tube in the bearing, lock tube has groove, plush copper stretches in the groove of lock tube, the right-hand member of bearing is provided with axis hole, axis hole is inserted with the latch shaft that has stage clip, latch shaft is provided with pin, stage clip is between the pin on the right side of bearing pin-and-hole and the latch shaft, and the latch shaft other end stretches out the back doorframe.During use, latch shaft and back interlocking, when open the back, latch shaft is not subjected to the external force effect, and latch shaft is inoperative to lock tube, and plush copper stretches in the groove of lock tube, and action bars can not rotate, and this interlocking can not be operated; When shutting the back door, the back door is pressed onto latch shaft, latch shaft jack-up lock tube, and plush copper just breaks away from the groove of lock tube, and action bars just can rotate, and this interlocking just can be operated.
The aforesaid operations bar is provided with screw, with a screw precession screw, just forms above-mentioned plush copper.
Be provided with pin-and-hole about above-mentioned bearing, lock tube is installed with movable axis, the pin-and-hole of active pin about bearing, and bearing is provided with the bar hole, and action bars passes the bar hole of bearing.Lock tube just can rotate in bearing like this.
Beneficial effect: of the present utility model by improvement to original this interlock, increase the reverse interlocking with the back door, must shut back door (shrouding) earlier can the operational grounding switch, simple in structure, good reliability, anti-error performance increases greatly.
The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 2 is that the utility model embodiment is at back door closure state schematic diagram.。
Fig. 3 is the schematic diagram of the utility model embodiment lock tube.
Fig. 4 the utility model embodiment lock tube master looks schematic diagram;
Fig. 5 looks schematic diagram for the utility model embodiment lock tube right side.
Among the figure: the 1-action bars; The 2-bearing; The 3-latch shaft; 4, doorframe; The 5-lock tube; The 6-stage clip; The 7-pin; The 8-screw; The 9-movable axis; The 21-pin-and-hole; The 22-installing hole; 23-bar hole; The 24-axis hole; The 51-groove.
Embodiment
As shown in Figure 1, 2, a kind of middle high-tension switch cabinet earthed switch operating mechanism interlock comprises action bars 1, bearing 2, and action bars 1 is provided with screw, stretches out screw with a screw 8, forms plush copper; In conjunction with Fig. 4, Fig. 5, bearing 2 is provided with two installing holes 22, and bearing about 2 is provided with pin-and-hole 24, lock tube 5 is installed with movable axis 9, and movable axis 9 pins are at the pin-and-hole 24 of bearing about 2, and bearing 2 is provided with bar hole 23, action bars 1 passes the bar hole 23 of bearing 2, is rotationally connected with doorframe 4.In conjunction with Fig. 3, lock tube 5 has groove 51, screw 8 afterbody plush coppers stretch in the groove 51 of lock tube 5, the right-hand member of bearing 2 is provided with axis hole 24, axis hole 24 is inserted with the latch shaft 3 that has stage clip 6, latch shaft 3 is provided with pin 7, and stage clip 6 is between the pin 7 on the right side of bearing 2 pin-and-hole 21 and the latch shaft 3, and latch shaft 3 other ends stretch out back doorframe 4.
As shown in Figure 1, latch shaft 3 and back interlocking, when open the back, latch shaft 3 is not subjected to the external force effect, and 3 pairs of lock tubes 5 of latch shaft are inoperative, and screw 8 afterbody plush coppers stretch in the groove 51 of lock tube 5, and action bars 1 can not rotate, and this interlocking can not be operated.
As shown in Figure 2, when shutting the back door, the back door is pressed onto latch shaft 3, latch shaft 3 jack-up lock tubes 5, and screw 8 afterbody plush coppers just break away from the groove 51 of lock tube 5, and action bars 1 just can rotate, and this interlocking just can be operated.
This interlock increases the reverse interlocking with the back door on the basis of former earthed switch operating mechanism interlock.After closing a floodgate, earthed switch opens back door (shrouding), but former interlocking operational grounding switch still, and this interlocking can not be operated, must shut back door (shrouding) earlier can the operational grounding switch.
