Detailed description of the invention
Describe the present invention below in conjunction with the accompanying drawings.
As shown in Figures 1 and 2, the present invention is a kind of breaker handcart of switch cabinet and earthed switch interlocking mechanism,
It includes 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 has downwardly extended side plate 12, in this U-board 11
Portion is symmetrically arranged on two with axis hole (not shown) in opening 13, and this side plate 12 is provided with locking plate hole (in figure not
Show).
In conjunction with seeing Fig. 3 and Fig. 4, this connecting plate 2 is triangular in shape, have first, second, third jiao of end (21,
22,23), this first jiao of end 21 is inwardly fixed with rotating shaft 24, and this rotating shaft 24 is through this support U-board 11
Two axis holes so that connecting plate 2 is connected with this support 1, this connecting plate 2 can rotate around support 1；This second jiao of end
Bearing pin 25 outwards it is fixed with, the operation by the third angle end 23 with switch cabinet grounding switch of this connecting plate 2 at 22
Pedestal (not shown) connects, and has fixing hole it addition, run through between this first jiao of end 21 and the third angle end 23
26。
This mounting angle plate 3 has straight plate 31, and these straight plate 31 two ends have each extended over the first bent plate 32 and second
Bent plate 33, this mounting angle plate 3 is solid with the U-board 11 of this support 1 by bolt 34 by this straight plate 31
Fixed, and this mounting angle plate 3 is fixed with breaker handcart of switch cabinet by this first bent plate 32 and the second bent plate 33
Position plate (not shown) is fixed, and makes to be formed between mounting angle plate 3 and handcart location-plate accommodation space 35.
One end of this locking plate 4 and the handcart lock hole (not showing in figure, for prior art) on this handcart location-plate
Corresponding, the other end is fixed through bearing pin 25 with this connecting plate 2 behind the locking plate hole of this support 1, so that locking plate
4 move linearly through left and right in accommodation space 35, locking plate hole under the rotation of connecting plate 2.
This torsion spring 5 is set around in the rotating shaft 24 between two axis holes of this U-board 11, and its one end is arranged in this company
In the fixing hole 26 of plate 2, the other end is resisted against side plate 12 bottom of this support 1.
In conjunction with seeing Fig. 5, when circuit breaker cart is in switch cubicle testing position, if earthed switch is in conjunction
Lock state (i.e. earthed switch receives after switching signal, earthed switch operation pedestal action, drive connecting plate 2 around
Rotationally clockwise, drive locking plate 4 is that handcart location-plate direction is moved to support 1 simultaneously to the left), now,
Handcart lock hole on handcart location-plate is blocked by locking plate 4, makes circuit breaker cart cannot be locked in testing position
Fixed, now must divide earthed switch, along with grounding switch tripping operates, connecting plate 2 is multiple under torsion spring 5 acts on
Position, locking plate 4 moves right, and handcart lock hole exposes, and circuit breaker cart could lock into place.
When circuit breaker cart testing position from switch cubicle is shaken and is entered operating position and be in operating position,
Locking plate 4 is kept out by the handcart lock hole on handcart location-plate, makes locking plate 4 not to be moved to the left, and connecting plate 2 is also
Rotationally clockwise, thus operational grounding can not can not switch, earthed switch also cannot be made to close a floodgate.
