Dynamic ground connection 3 quick rotation of transmission shaft of armband, actuator 31 is with 51 turns of actuating arm of drive in ground connection 3 separating brake rotation process of transmission shaft
It is dynamic, so that transmission mechanism 5 drives the ground connection output shaft 4 to carry out separating brake rotation, and grounding contact pair is driven by ground connection output shaft
The acting of separating brake needed for outer offer and impulse stroke.When being converted into gate-dividing state from "on" position, actuator drives actuating arm
On pin shaft part and locking level formed lock fit, to keep open position to limit.
It is grounded operating mechanism making process：The ground connection operating shaft 2 is driving ground connection transmission shaft 3 just by gear transmission structure
To rotation, actuating arm 51 is locked in combined floodgate first half term and remains stationary, by actuator 31 with ground connection transmission shaft combined floodgate rotation
Driving locking level 61 and actuating arm 51 unlock cooperation in the process, and at the same time, the first elastic component 7 is rotated in ground connection transmission shaft
It is transitted in the process by energy storage and releases energy, and ground connection 3 quick rotation of transmission shaft is driven by rocker arm under de-energized state, and then drive
Transmission mechanism drives the ground connection output shaft 4 to carry out combined floodgate rotation, and it is required to drive grounding contact externally to provide by output shaft
Combined floodgate acting and impulse stroke.
The operating device of the present embodiment further includes isolated operation mechanism, and the isolated operation mechanism includes isolated operation axis 8
With the isolation transmission shaft 9 driven by the isolated operation axis 8, the isolation transmission shaft 9 is parallel with the ground connection transmission shaft 3 to be set
It sets, for the safety operation for guaranteeing disconnecting switch, realizes that the room machine of isolator operating mechanism and isolator operating mechanism closes
Lock prevents maloperation occur disconnecting switch is closed a floodgate, disconnecting switch separating brake and disconnecting switch are grounded between three positions, it is described every
From being provided between transmission shaft 9 and the ground connection transmission shaft 3 in be isolated that "on" position limits ground connection transmission shaft 3 rotation the
One interlocking mechanism, and, the second interlocking mechanism that isolation transmission shaft 9 rotates described in contact of earth state limit.
Illustrate the specific set-up mode of the first interlocking mechanism and the second interlocking mechanism below with reference to Fig. 3-5：
First interlocking mechanism includes the first limit plate 32 being fixedly installed on the ground connection transmission shaft 3, and, it is right
First limit plate 32 is answered to be fixedly installed on the second limit plate 91 on the isolation transmission shaft 9, second limit plate 91
When the isolation transmission shaft 9 closes a floodgate with first limit plate 32 with respect to or offset, at isolated operation mechanism as shown in Figure 5
In closing position, being grounded operating mechanism at this time can not be closed a floodgate by the limitation of the first interlocking mechanism.As a kind of specific set-up mode, institute
Stating the second interlocking mechanism includes the third limit plate 54 taken shape on the actuating arm 51, and the corresponding third limit plate 54 is solid
Surely the 4th limit plate 92 being set on the isolation transmission shaft 9, the third limit plate 54 close a floodgate in the ground connection transmission shaft 3
When it is opposite with the 4th limit plate 92 or offset, ground connection operating mechanism as shown in Figure 3 be in closing position, and isolation is grasped at this time
Making mechanism can not be closed a floodgate by the limitation of the second interlocking mechanism.By above structure, it is ensured that the operating position of operating device is not
In isolation closing position, it is exactly to realize mechanical latching in isolation open position or earthing position, prevents major loop electrification from closing ground
Knife avoids maloperation bring from endangering, to meet the relevant regulations of safety operation：Need to first separate earthing switch, then close every
Pass is left, prevents from just closing disconnecting switch before not dividing earthing switch, or just closes earthing switch before preventing not point disconnecting switch, is protected
Demonstrate,prove operational safety.
Embodiment 2
It include isolator operation device described in embodiment 1 the present embodiment provides a kind of disconnecting switch, thus from
So have the advantages that due to above-mentioned isolator operation device is set bring all, be able to achieve close a floodgate in isolation, be isolated separating brake and
Conversion between three stations of contact of earth, operating position are uniquely, to prevent major loop electrification from closing earthing knife-switch, maloperation is avoided to bring
Harm.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes among the protection scope created still in the utility model.
