Abstract
The utility model discloses a disconnecting switch fastener for a switch cabinet, belonging to the technical field of the safety lock device. The disconnecting switch fastener is arranged between a disconnecting switch and a breaker of a switch cabinet; the disconnecting switch comprises a disk mechanism stop plate; a through hole on the disk mechanism stop plate is provided with a stop head rod in a controlled mode for limiting the disk mechanism stop plate to rotate a handle; the stop head rod is slidingly arranged on a support plate; the end of the stop head rod is connected with a crank arm of the breaker; and an elastic reset mechanism is arranged between the stop head rod and the support plate. The disconnecting switch fastener for a switch cabinet prevents the breaker operates the disconnecting switch on load in an on-position state, thus avoiding misoperation, and is widely applied to the high voltage switch cabinet.
Description
Technical field
The utility model relates to the security lock arrangement technical field, relates in particular to a kind of locking device that prevents circuit breaker in "on" position on-load disconnecting switch operation.
Background technology
At present, XGN-12 type high-tension switch cabinet use isolated operation mechanism as disk mechanism (model: JSXGN-12), though the detailed step of operating personnel's operating mechanism is arranged above the disk mechanism; Operating personnel often and not exclusively operate according to the operating procedure inlet wire above the mechanism, sometimes but in actual use; Operating personnel are in order to save time, at circuit breaker not under the situation of separating brake, and deciliter isolating switch of mistake; The insulating contact starting the arc causes the phase fault accident.Therefore the isolating switch of present switch cubicle and the operation between the circuit breaker do not have safety device, have the hidden danger of misoperation.
The utility model content
The utility model technical problem to be solved is: a kind of switch cubicle separation switch lock device is provided, prevents that circuit breaker from "on" position on-load disconnecting switch operation, having avoided misoperation.
For solving the problems of the technologies described above; The technical scheme of the utility model is: the switch cubicle separation switch lock device; Be installed between the isolating switch and circuit breaker of switch cubicle; Said isolating switch comprises that disk mechanism ends plate, and said disk mechanism ends constraint in the through hole on the plate and is equipped with and is used for the head rod that ends that limit disk mechanism rotary handle rotates, and the said head rod that ends is slidingly mounted on the supporting bracket; Said end of ending head rod connects the connecting lever of circuit breaker, and said ending between head rod and the supporting bracket is provided with flexible restoring organ.
As a kind of improvement, the said head rod that ends is connected through flexible cable with the connecting lever of circuit breaker, and said flexible cable is wound on the fixed pulley, and said fixed pulley rotates and is installed on the said supporting bracket.
As further improvement, said flexible restoring organ comprises the compression spring that is sheathed on the said only head rod.
After having adopted technique scheme; The beneficial effect of the utility model is: owing to designed only head rod between isolating switch and the circuit breaker, it slides by the connecting lever control of circuit breaker to end head rod, and an end that ends head rod inserts in disk mechanism and ends in the through hole on the plate; When circuit breaker in the separating brake position; End head rod extraction disk mechanism and end the through hole on the plate, disk mechanism rotary handle just can rotate, and carries out a deciliter isolating switch, the operation of ground connection cutter; When circuit breaker at closing position, end head rod and insert disk mechanism and end the through hole on the plate, disk mechanism rotary handle just can not rotate, isolating switch just can't be operated, this has just been avoided misoperation, has improved the handling safety performance of switch cubicle.
Be connected through flexible cable with the connecting lever of circuit breaker owing to end head rod, and supporting bracket is provided with a fixed pulley, it is linear slide that flexible cable can maintain one section through fixed pulley, influenced because of the swing of connecting lever, has not guaranteed accuracy of action.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1, plate ends in disk mechanism, and 2, the connecting lever of circuit breaker, 3, end head rod, 4, the compression spring, 5, supporting bracket, 6, flexible cable, 7, fixed pulley.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Shown in accompanying drawing; A kind of switch cubicle separation switch lock device; Be installed between the isolating switch and circuit breaker of switch cubicle, said isolating switch comprises that disk mechanism ends plate 1, said disk mechanism end constraint in the through hole on the plate 1 be equipped be used for that limit disk mechanism rotary handle rotates end head rod 3; The said head rod 3 that ends is slidingly mounted on the supporting bracket 5; Said end of ending head rod 3 connects the connecting lever 2 of circuit breaker, and said ending between head rod 3 and the supporting bracket 5 is provided with flexible restoring organ, and said flexible restoring organ comprises the compression spring 4 that is sheathed on the said only head rod 3.
The said head rod 3 that ends is connected through flexible cable 6 with the connecting lever 2 of circuit breaker; Said flexible cable 6 is wound on the fixed pulley 7; Said fixed pulley 7 rotates and is installed on the said supporting bracket 5; Usually, an end of flexible cable 6 is fixed in an only end of head rod 3, and the other end of flexible cable 6 is fixed on the connecting lever 2 of circuit breaker.Usually, flexible cable 6 can be chosen as steel wire rope, nylon rope, cotton thread rope etc.
During use, when circuit breaker in the separating brake position, the connecting lever of circuit breaker 2 drives and ends head rod 3 and extract disk mechanisms out and end the through hole on the plate 1, disk mechanism rotary handle just can rotate, and carries out a deciliter isolating switch, the operation of ground connection cutter; When circuit breaker at closing position, under the effect of compression spring 4, end head rod 3 and insert disk mechanisms and end the through hole on the plate 1, disk mechanism rotary handle just can not rotate, isolating switch just can't be operated.Through this safety device, just avoided the misoperation of circuit breaker in "on" position on-load disconnecting switch operation, improved the handling safety performance of switch cubicle.
The utility model is not limited to above-mentioned concrete execution mode, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection range of the utility model.
