Abstract
The utility model relates to an interlocking device in a switch cabinet. The interlocking device comprises cams (1), a long push rod assembly (2), a long bottom board (3), a double-shaft reinforcing board (4), a guide shaft sleeve (5), a guide nail (6), a lengthened main shaft (7), a four-position fixing sleeve (8), and a PVC shaft sleeve (9). Two switches which are provided with the interlocking device are in an interlocked state: only one of the two switches can be switched on, and the other switch can be switched off, and if the other switch is expected to be switched on, the first one switch must be switched off firstly and then switched on; or both of the two switches can be switched off. The interlocking device is advantageous in high reliability, simple structure, long service life and the like.
Description
Technical field
The utility model relates to the high-voltage vacuum load switch field, relates in particular to interlock between a kind of switch cubicle.
Background technology
At present, existing switch cubicle adopts electrical interlock and mechanical lock usually at power supply entering line.Electrical interlock must have the support of power supply, and the non-transformer place just can't be realized chain; Aspect mechanical lock, just select the closing locking calutron, the closing locking calutron adopts electromagnetic lock usually, electromagnetic lock also must power supply support and the long-time energising of electromagnetic lock after failure rate high, so the above generation that either way can't fundamentally prevent misoperation.
Summary of the invention
The utility model is for above problem, provides that a kind of reliability is high, simple in structure, interlock between the switch cubicle of long service life.
The technical scheme that its technical problem that solves the utility model adopts is:
Interlock between a kind of switch cubicle comprises that cam (1), the assembling of long push rod (2), elongated base plate (3), diaxon stiffener (4), guideway (5), guide pin (6), lengthening main shaft (7), four fixed covers (8), PVC axle sleeve (9) is characterized in that:
When two switches all are in gate-dividing state and since long push rod assembling (2) can be between the concave surface of two cams (1) free play, can and only can carry out closing operation to any switch at this moment; When any switch closes a floodgate, all can impel the cam (1) of closing switch that long push rod assembling (2) is pushed in cam (1) concave surface at another switch place.
After the First switch closes a floodgate, because the cam (1) of First switch has rotated direction, impel long push rod assembling (2) top in the concave surface of second switch cam (1); At this moment, long push rod assembling (2) can not be moved between two cams (1) fully, and this is with regard to so that second switch can't carry out closing operation
If second switch will be closed a floodgate, must be first with First switch separating brake, this timer is in Fig. 1 state, long push rod assembling (2) can be between two cams (1) concave surface free play, so just second switch can be closed a floodgate, be in state shown in Figure 4 behind the combined floodgate.
In sum, interlock between a kind of switch cubicle of the utility model, two switches that this device is set are in Interlock Status, and two switches can only have a switch to close a floodgate, and another separating brake if want second combined floodgate, must will close a floodgate behind the First separating brake first again; Perhaps two separating brakes all have the characteristics such as, long service life high, simple in structure in reliability.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is plan structure cutaway view of the present utility model;
Fig. 2 is the front section view when two switches all are in separating brake of the present utility model;
Fig. 3 is that the First switch of working as of the present utility model is in combined floodgate, the front section view when second switch is in gate-dividing state;
Fig. 4 is that the First switch of working as of the present utility model is in separating brake, the front section view when second switch is in "on" position.
Embodiment
Below in conjunction with the drawings and specific embodiments interlock between a kind of switch cubicle of the present utility model is further described.
Shown in accompanying drawing 1～4, a kind of device for interlocking between switch cubicle comprises cam (1), the assembling of long push rod (2), elongated base plate (3), diaxon stiffener (4), guideway (5), guide pin (6), lengthens main shaft (7), four fixed covers (8).Shown in accompanying drawing 1～2, when two switches all are in gate-dividing state since long push rod assembling (2) can be between the concave surface of two cams (1) free play, can and only can carry out closing operation to any switch at this moment; When any switch closes a floodgate, all can impel the cam (1) of closing switch that long push rod assembling (2) is pushed in cam (1) concave surface at another switch place.
As shown in Figure 3, after the First switch closes a floodgate, because the cam (1) of First switch has rotated direction, impel long push rod assembling (2) top in the concave surface of second switch cam (1); At this moment, long push rod assembling (2) can not be moved between two cams (1) fully, and this is with regard to so that second switch can't carry out closing operation.
Shown in accompanying drawing 2,4, if second switch will be closed a floodgate, must be first with First switch separating brake, this timer is in Fig. 1 state, long push rod assembling (2) can be between two cams (1) concave surface free play, so just second switch can be closed a floodgate, be in state shown in Figure 4 behind the combined floodgate.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solution of the present invention scope and replacing all should be included in the protection range of the present utility model.
Claims (1)
1. interlock between a switch cubicle comprises cam (1), the assembling of long push rod (2), elongated base plate (3), diaxon stiffener (4), guideway (5), guide pin (6), lengthens main shaft (7), four fixed covers (8), PVC axle sleeve (9) is characterized in that:
When two switches all are in gate-dividing state and since long push rod assembling (2) can be between the concave surface of two cams (1) free play, can and only can carry out closing operation to any switch at this moment; When any switch closes a floodgate, all can impel the cam (1) of closing switch that long push rod assembling (2) is pushed in cam (1) concave surface at another switch place;
After the First switch closes a floodgate, because the cam (1) of First switch has rotated direction, impel long push rod assembling (2) top in the concave surface of second switch cam (1).
