Embodiment
Describe the present invention below in conjunction with accompanying drawing.
As shown in Figures 1 and 2, the present invention is a kind of breaker handcart of switch cabinet and earthed switch interlocking device, and it comprises support 1, connecting plate 2, mounting angle plate 3, locking plate 4 and torsion spring 5.Wherein:
This support 1 has U-board 11, and this U-board 11 is extended with side plate 12 downwards, and this U-board 11 top is provided with axis hole (not shown) in opening 13 bilateral symmetry, and this side plate 12 is provided with locking plate hole (not shown).
In conjunction with see Fig. 3 and Fig. 4, this connecting plate 2 is triangular in shape, has first, second, third jiao of end (21,22,23), and this first jiao of end 21 is inwardly fixed with rotating shaft 24, this rotating shaft 24 is connected with this support 1 to make connecting plate 2 through two axis holes of this support U-board 11, and this connecting plate 2 can rotate around support 1; This second jiao of end 22 place is outwards fixed with bearing pin 25, and this connecting plate 2 is connected with the operation pedestal (not shown) of switch cabinet grounding switch by triangle end 23, in addition, runs through and have fixing hole 26 between this first jiao of end 21 and triangle end 23.
This mounting angle plate 3 has straight plate 31, these straight plate 31 two ends are extended with the first bent plate 32 and the second bent plate 33 respectively, this mounting angle plate 3 is fixed by the U-board 11 of bolt 34 with this support 1 by this straight plate 31, and this mounting angle plate 3 is fixed with breaker handcart of switch cabinet location-plate (not shown) by this first bent plate 32 and the second bent plate 33, makes to form accommodation space 35 between mounting angle plate 3 and handcart location-plate.
Handcart lock hole on one end of this locking plate 4 and this handcart location-plate is (not shown in the figures, for prior art) corresponding, the other end is fixed with the bearing pin 25 of this connecting plate 2 through behind the locking plate hole of this support 1, to make locking plate 4 left and right rectilinear movement in accommodation space 35 through locking plate hole under the rotation of connecting plate 2.
In rotating shaft 24 between two axis holes that this torsion spring 5 is set around this U-board 11, its one end is arranged in the fixing hole 26 of this connecting plate 2, and the other end is resisted against side plate 12 bottom of this support 1.
In conjunction with see Fig. 5, when circuit breaker cart is in switch cubicle test position, if earthed switch is in "on" position (after namely earthed switch receives switching signal, the action of earthed switch operation pedestal, connecting plate 2 is driven to rotate around support 1 clockwise direction, drive locking plate 4 to be that handcart location-plate direction is moved left) simultaneously, now, handcart lock hole on handcart location-plate is blocked by locking plate 4, circuit breaker cart cannot be locked in test position, now earthed switch must be divided, along with grounding switch tripping operation, connecting plate 2 resets under torsion spring 5 acts on, locking plate 4 moves right, handcart lock hole exposes, circuit breaker cart could lock and put in place.
When circuit breaker cart test position from switch cubicle shake enter service position and be in service position time, locking plate 4 is kept out by the handcart lock hole on handcart location-plate, locking plate 4 can not be moved to the left, connecting plate 2 can not rotate by clockwise direction, thus can not operational grounding switch, earthed switch also just can not be made to close a floodgate.
