Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, and be not used in restriction invention.
Fig. 1 shows the structure of the actuating mechanism of ring main unit major loop that the embodiment of the present invention provides and ground connection deciliter.For convenience of explanation, illustrate only part related to the present invention.
This actuating mechanism comprises: the first manual action disk 1, spring supporting post 2, the manual action disk 4 of major loop action disk 3, second, landing operation dish 5;
First manual action disk 1 is in transmission connection with one end of spring supporting post 2, and spring supporting post 2 is also in transmission connection with major loop action disk 3, and the other end of spring supporting post 2 and the second manual action disk 4 and landing operation dish 5 are in transmission connection.
In embodiments of the present invention, the first manual action disk 1 is also in transmission connection with ring main unit major loop mechanism handle.
In embodiments of the present invention, the second manual action disk 4 is also in transmission connection with ring main unit earthing mechanism handle.
In embodiments of the present invention, this actuating mechanism is also provided with ground connection locking device, and when major loop is in "on" position, ground connection is in gate-dividing state, and now ground connection locking device moves to assigned address, makes landing operation dish 5 cannot action.
Below in conjunction with drawings and the specific embodiments, application principle of the present invention is further described.
As shown in Figure 1, Figure 2 and Figure 3, rotate ring main unit major loop mechanism handle, drive manual activity dish to turn clockwise, spring supporting post 2 is moved down, thus drive major loop action disk 3 to be rotated clockwise to assigned address, major loop is closed a floodgate; Otherwise major loop separating brake.
Rotate ring main unit earthing mechanism handle, drive manual activity dish to turn clockwise, spring supporting post 2 is moved down, thus drive landing operation dish 5 to be rotated clockwise to assigned address, make contact of earth; Otherwise ground connection separating brake.
When major loop is in "on" position, ground connection is in gate-dividing state, and now ground connection locking device moves to assigned address, makes landing operation dish 5 cannot action, thus ensure that device security.
The actuating mechanism of the ring main unit major loop that the embodiment of the present invention provides and ground connection deciliter, by the first manual action disk 1, spring supporting post 2, major loop action disk 3, second manual action disk 4 and landing operation dish 5 are formed, first manual action disk 1 is in transmission connection with one end of spring supporting post 2, spring supporting post 2 is also in transmission connection with major loop action disk 3, the other end of spring supporting post 2 and the second manual action disk 4 and landing operation dish 5 are in transmission connection, first manual action disk 1 is also in transmission connection with ring main unit major loop mechanism handle, second manual action disk 4 is also in transmission connection with ring main unit earthing mechanism handle, this actuating mechanism is also provided with ground connection locking device, when major loop is in "on" position, ground connection is in gate-dividing state, now ground connection locking device moves to assigned address, make landing operation dish 5 cannot action, produce and use cost lower, easy for installation, simple to operate, stop the generation of misoperation phenomenon, practical, there is stronger propagation and employment be worth.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
