Embodiment
Below in conjunction with accompanying drawing of the present utility model, most preferred embodiment of the present utility model is described in more detail.
Fig. 1 is that interlock of the present utility model is installed in schematic diagram on the switch cubicle door, Figure 2 shows that the structure explosive view of interlock of the present utility model, and the structure of the interlock of this utility model is described below in conjunction with Fig. 1 and Fig. 2.This interlock comprises square rail plate 3, first backguy 4 and the first white pipe 41, tower spring 5, ground connection locking plate 6, second backguy 7 and the second white pipe 71, a few word spring 8 and interlocking shaft 9.Described parts are fixed on the interlocking fixed mount 2, interlocking shaft 9 moves up and down along the hole 31 in the middle of the square rail plate 3, tower spring 5 is contained on the square rail plate 3 and acts on the pad that fixes with interlocking shaft 9, first backguy 4 reaches with the upper end of interlocking shaft 9 to be fixed, second backguy 7 and drive ground connection locking plate 6 slide in the square groove 10 of square rail plate 3, wherein ground connection locking plate 6 left ends have socket 61 can insert interlocking shaft 9, a few word springs 8 are contained between square rail plate 3 and the interlocking fixed mount 2 and block interlocking shaft 9, and the socket on the installation sheet of cabinet door 1 can pass the groove of interlocking shaft 9 bottoms.
Interlock operation principle of the present utility model is: second backguy 7 drives ground connection locking plate 6 and moves along the square groove 10 of square rail plate 3 and the second fixing white pipe 71 together, when the earthed switch ground connection of switch cubicle is operated, ground connection locking plate 6 moves right, when earthed switch was in the isolated location, ground connection locking plate 6 inserted the middle groove 92 of interlocking shaft 9 or goes up in the groove 93.Interlocking shaft lower groove 91 is blocked at bayonet socket 81 places of a few word springs 8, when the switch cubicle door leaves a few word spring openings 82 places, a few word spring of expansible bayonet socket 81 places, thereby make a few word springs 8 no longer block interlocking shaft 9, interlocking shaft 9 can move downward under the action of gravity of switch cubicle door 1, and pass through second backguy, 7 drives relevant isolating switch or the disengagement of earthed switch barrier sheet, thereby allow to finish the normal running of isolating switch or earthed switch.
Below novel interlocking device state and corresponding switching manipulation are described in conjunction with the correlation diagram file.
Fig. 3 is the unlock state schematic diagram when the cabinet door is closed of interlock of the present utility model, has only when isolating switch ground connection, and ground connection locking plate 6 is thrown off part interlocking shaft 9, and interlocking shaft 9 could move.Can close and close the switch cubicle door this moment, when closing a switch cabinet behind the door, drives second backguy 7 and move down, thereby make the catch of original handle hole remove, the operation of can achieve a butt joint ground switch or isolating switch.
Fig. 4 is the lock-out state schematic diagram when the cabinet door is closed of interlock of the present utility model, after the switch cubicle door gets togather, but the operational grounding switch is to the isolated location, because second backguy 7 drives ground connection locking plate 6 to left movement under the effect of earthing mechanism, thereby stick in interlocking shaft 9, mean that having high voltage at any time produces this moment, thereby so the switch cubicle door can not move up and take the switch cubicle door away, thereby guarantee operating personnel's safety.
Fig. 5 is the unlock state schematic diagram when the cabinet door is opened of interlock of the present utility model, and after earthed switch was in earthing position, ground connection locking plate 6 was thrown off interlocking shaft 9, under the reliable ground state, the switch cubicle door can be taken off.
Fig. 6 is the lock-out state schematic diagram when the cabinet door is opened of interlock of the present utility model, and for example the situation of wireline test is carried out at the switch cubicle scene.This moment, the switch cubicle door took off, and the switch cubicle isolating switch is in isolation, and interlocking shaft 9 is owing to blocked by a few word springs 8, and interlocking shaft 9 can not be moved up and down by the switch cubicle door, can guarantee field personnel's safety.
Although disclose preferred embodiment of the present utility model and accompanying drawing for the purpose of illustration, the person skilled in the art in the spirit and scope that do not break away from the utility model and appended claim, can do various replacements, variation and retouching.Therefore, the utility model should not be limited to preferred embodiment and the disclosed content of accompanying drawing, and protection range of the present utility model is as the criterion with the scope that appending claims was defined.
