Abstract
The utility model discloses an operating mechanism for an isolating switch in the isolating switch technical field. The isolating switch is composed of a pole pin, an operating shaft, a limit pin, a three-phase lifting plate, an operating mechanism fixing plate, a connecting rod, a turn arm and guide sliding rods; the operating mechanism is provided with two guide sliding rods which are in parallel with each other and are respectively arranged at the left and the right sides of the operating mechanism fixing plate; the three-phase lifting plate is coated on two guide sliding rods; one end of the turn arm is welded with the operating shaft, and the other end of the turn arm is hinged with one end of the connecting rod through a column pin; one end of the connecting rod is hinged with the three-phase lifting plate, a long pole pin which is connected with an insulating rod of the isolating switch runs through the three-phase lifting plate, and the limit pin is arranged at one side of the connecting rod. The isolating switch has the advantages that the device can be used in the isolating switch, the structure is simple, the operation is convenient and labor-saving, and the reliability is high with nonreturn function.
Description
Technical field
The utility model relates to isolating switch, particularly the operating mechanism of isolating switch.
Background technology
At present, the operating mechanism of the indoor high-voltage isolating switch of domestic market substantially all has positioner, promptly all uses alignment pin lock operation mechanism at closing position and separating brake position, closes a floodgate or separating brake to prevent that isolating switch is unexpected.At first extract the alignment pin release when operation, operation puts isolator operation in place then, and alignment pin is lock operation mechanism once more.In use, because operating mechanism is subjected to the effect of isolating switch counter-force, alignment pin often occurring can not pull out, perhaps operate too quickly, the stressed bending of alignment pin causes alignment pin and location hole to cooperate, can not the positive lock operating mechanism, therefore this operating mechanism reliability is not high, can not satisfy the requirement of switch cubicle.
The utility model content
The purpose of this utility model provide a kind of simple in structure, easy and simple to handle, have non-return function, a isolator operating mechanism that reliability is high.
The purpose of this utility model is achieved in that a kind of operating mechanism of isolating switch, comprise the stock pin, operating axis, spacer pin, the three-phase riser, the operating mechanism fixed head, connecting rod, connecting lever and guiding slide bar, described guiding slide bar has two also to distinguish secured in parallel in the operating mechanism fixed head left and right sides, the three-phase riser is sleeved on two guiding slide bars, one end of connecting lever and operating axis welding, the other end of connecting lever is hinged through straight pin and connecting rod one end, the other end of connecting rod and three-phase riser are hinged, the stock pin that is connected with the insulated tension pole of isolating switch penetrates described three-phase riser, and spacer pin is arranged on connecting rod one side.
During this device work, the operating mechanism fixed head maintains static, operating axis can rotate around its axle center, operating axis turns clockwise under gate-dividing state, the connecting lever that is welded on the operating axis forces the three-phase riser to do rectilinear motion downwards along the guiding slide bar drive link, and the insulated tension pole that the stock pin drives isolating switch moves downward.When connecting rod contacts with spacer pin, finish the isolating switch closing operation, connecting rod and connecting lever keep linear state, make it can remain on the dead-centre position, in like manner, under "on" position, connecting rod and connecting lever also keep linear state, even at this moment the three-phase riser is subjected to the counter-force that isolating switch transmits, also can not move up and down, realized non-return function.When being rotated counterclockwise operating axis, the connecting lever that is welded on the operating axis forces the three-phase riser upwards to do rectilinear motion along the guiding slide bar drive link, and the insulated tension pole that the stock pin drives isolating switch moves upward.When connecting rod contacts with spacer pin, finish the isolating switch sub-switching operation.Connecting rod and connecting lever also can remain on the dead-centre position, even at this moment the three-phase riser is subjected to the counter-force that isolating switch transmits, also can not move up and down, and have realized non-return function equally.This device can reliably be applied in the isolating switch, and compared with prior art, it is simple in structure, uses reliable.

Embodiment
As Fig. 1-5, a kind of operating mechanism of isolating switch, comprise stock pin 7, operating axis 1, spacer pin 9, three-phase riser 5, operating mechanism fixed head 6, connecting rod 4, connecting lever 3 and guiding slide bar 8, described guiding slide bar 8 has two also to distinguish secured in parallel in operating mechanism fixed head 6 left and right sides, three-phase riser 5 is sleeved on two guiding slide bars 8, one end of connecting lever 3 and operating axis 1 welding, the other end of connecting lever 3 is hinged through straight pin 2 and connecting rod 4 one ends, the other end of connecting rod 4 and three-phase riser 5 are hinged, the stock pin 7 that is connected with the insulated tension pole of isolating switch penetrates described three-phase riser 5, and spacer pin 9 is arranged on connecting rod 4 one sides.
During its work, operating mechanism fixed head 6 maintains static, operating axis 1 can rotate around its axle center, operating axis 1 turns clockwise under gate-dividing state, the connecting lever 3 that is welded on the operating axis 1 forces three-phase riser 5 to do rectilinear motion downwards along guiding slide bar 8 drive link 4, and the insulated tension pole that stock pin 7 drives isolating switch moves downward.When connecting rod 4 contacts with spacer pin 9, finish the isolating switch closing operation, connecting rod 4 keeps linear state with connecting lever 3, make it can remain on the dead-centre position, in like manner, under "on" position, connecting rod 4 also keeps linear state with connecting lever 3, even at this moment three-phase riser 5 is subjected to the counter-force that isolating switch transmits, also can not move up and down, realized non-return function.When being rotated counterclockwise operating axis 1, the connecting lever 3 that is welded on the operating axis 1 forces three-phase riser 5 upwards to do rectilinear motion along guiding slide bar 8 drive link 4, and the insulated tension pole that stock pin 7 drives isolating switch moves upward.When connecting rod 4 contacts with spacer pin 9, finish the isolating switch sub-switching operation.Connecting rod 4 also can remain on the dead-centre position with connecting lever 3, even at this moment three-phase riser 5 is subjected to the counter-force that isolating switch transmits, also can not move up and down, and has realized non-return function equally.
