Abstract
The invention discloses an interlocking device of a switch cabinet. The interlocking device of the switch cabinet comprises an auxiliary switch controlled by a switch-on position state and a switch-off position state of a main switch. A rotary shaft of the auxiliary switch is connected with an output crank arm. The output crank arm, a connecting rod and a transmission crank arm form a connecting rod mechanism, wherein the connecting rod and the transmission crank arm are hinged to each other. The transmission crank arm is installed to the fixed part in the switch cabinet through a rotary shaft in the middle of the transmission crank arm. A lifting rod which lifts along with swinging of the transmission crank arm is hinged to one end of the transmission crank arm. The lower end of the lifting rod is connected with a baffle which can lift along with the lifting rod. The baffle is located on the inner side of a panel of the switch cabinet. The panel of the switch cabinet is provided with an operating hole, an operating handle of an earthing switch can be plugged into the operating hole, and the operating hole can be opened or closed through lifting of the baffle. The connecting rod and the transmission crank arm are connected in a welded mode. The diameter of the connecting rod is greater than or equal to 12 mm. By the adoption of the interlocking device of the switch cabinet, the connecting rod can be prevented from falling off, and the stability of the connecting rod is improved.
Description
Technical field
The present invention relates to the modular construction of high-tension switch cabinet, particularly relate to a kind of interlocking device of switch cabinet.
Background technology
In the structure of high-voltage switch gear, for ensureing the safe, reliable of operation, conventionally need to main switch and earthed switch point, closing operation interlocks, and only allows main switch can operate earthed switch under particular state.
Existing interlock, because the divide-shut brake of switch acts frequently, stationary links both sides be plain cushion and nut, time one nut of long stationary links can become flexible and leave gradually, thereby connecting rod is come off.And connecting rod below is A facies tract goddess of lightning row, connecting rod comes off and meets A facies tract goddess of lightning row, and A phase short circuit grounding accident will occur.
Summary of the invention
The object of this invention is to provide a kind of interlocking device of switch cabinet, can solve due to the divide-shut brake of the switch problem that causes connecting rod to come off that acts frequently.
For achieving the above object, the invention provides following scheme:
A kind of interlocking device of switch cabinet, comprise one by main switch point, the auxiliary switch of closing position state control,
The rotating shaft of this auxiliary switch is connected with an output toggle arm, output toggle arm forms a linkage with the connecting rod being hinged and transmission crank arm, transmission crank arm is arranged on the standing part in switch cubicle by the rotating shaft at its middle part, one end of transmission crank arm is also hinged with one and can moves and the elevating lever of lifting with the swing of transmission crank arm, elevating lever lower end is connected with one can be with the baffle plate of lifter rod lifting, this baffle plate is positioned at the inner side of switch cabinet panel, on switch cabinet panel, have the handle hole inserting for earthed switch operating grip, the lifting of baffle plate can be opened or " locked in " operation hole,
The junction of described connecting rod and described transmission crank arm is welding, and the diameter of described connecting rod is more than or equal to 12 millimeters.
Optionally, the surface of described connecting rod (3) scribbles corrosion resistant coating.
According to specific embodiment provided by the invention, the invention discloses following technique effect:
Interlocking device of switch cabinet of the present invention, by the junction in described connecting rod and described transmission crank arm, described connecting rod and described transmission crank arm are welded together, the diameter of described connecting rod is more than or equal to 12 millimeters, can avoid causing the nut of stationary links loosening because the divide-shut brake of switch acts frequently, and then the problem that causes connecting rod to come off, the stability of increase connecting rod.
Brief description of the drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of a kind of interlocking device of switch cabinet embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of a kind of interlocking device of switch cabinet embodiment of the present invention.As shown in Figure 1:
This interlocking device of switch cabinet includes dividing by main switch, the auxiliary switch 1 of closing position state control, the rotating shaft of this auxiliary switch is connected with an output toggle arm 2, output toggle arm forms a linkage with the connecting rod 3 and the transmission crank arm 4 that are hinged, transmission crank arm is arranged on the standing part in switch cubicle by the rotating shaft 5 at its middle part, one end of transmission crank arm 4 is also hinged with one and can moves and the elevating lever 6 of lifting with the swing of transmission crank arm, elevating lever lower end is connected with one can be with the baffle plate of lifter rod lifting 7, this baffle plate is positioned at the inner side of switch cabinet panel 8, on switch cabinet panel, have the handle hole 9 inserting for earthed switch operating grip, the lifting of baffle plate 7 can be opened or " locked in " operation hole 9.
Described connecting rod 3 is welding with the junction of described transmission crank arm 4, and the diameter of described connecting rod 3 is more than or equal to 12 millimeters.
Because described connecting rod 3 is welding with the junction of described transmission crank arm 4, the diameter of described connecting rod 3 is more than or equal to 12 millimeters, so can avoid causing the nut of stationary links loosening because the divide-shut brake of switch acts frequently, so the problem that causes connecting rod to come off, the stability of increase connecting rod.
In practical application, get rusty in order to prevent that connecting rod is corroded, the surface of described connecting rod 3 can also scribble corrosion resistant coating.
Applied specific case herein principle of the present invention and execution mode are set forth, the explanation of above embodiment is just for helping to understand method of the present invention and core concept thereof; Meanwhile, for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications.In sum, this description should not be construed as limitation of the present invention.
