Specific embodiment
The embodiment 1 of GIS device is as shown in Figure 1 and 2：GIS device is that Cubicle Gas-Insulated Switchgear includes open circuit
Device（In figure is not shown）And tri-station isolating switch, tri-station isolating switch includes trigger device and the ground connection of left and right setting is touched
Head and static contact（In figure is not shown）.Trigger device includes moving contact and screw 2.Tri-station isolating switch also includes being operated
The leading screw 3 that the axis that mechanism drives extends in left-right direction, the female thread screw thread of leading screw 3 and screw 2 coordinates and realizes being driven, silk
Thick stick 3 and screw 2 are made by insulant.Moving contact includes the moving contact body 1 of tubular, moving contact body axially along left and right
Direction extends, and the inwall two ends of moving contact body 1 connect integrally formed with the first screw connection bump part 4 and the second screw respectively
Connect bossing（In figure is not shown）, between screw 2 and moving contact body 4 between first, second screw connection bump part
There is annular gap 5.First screw connection bump part 4 and the second screw connection bump part are constituted for being connected with screw
Screw connection bump, in the present embodiment, the first screw connection bump part 4, the second screw connection bump part are annular
Structure.First screw connection bump part 4 is connected female thread with being provided with the inner peripheral surface of the second screw connection bump part, silk
Female consistent with the length of moving contact, the two ends of screw are provided with and the corresponding connection external screw thread connecting screw-internal thread fit, connect interior
The rotation direction of screw thread is oppositely oriented with the female thread of screw.Moving contact and screw adopt with A-A to the symmetrical knot as line of symmetry
Structure.
During use, operating mechanism drives leading screw to rotate, and leading screw is driven with screw and realizes driving moving contact to move left and right, and moves
Contact moves left and right the switching in earthing position, isolated location and closing position for the achievable moving contact.The length of screw and contact
Body length consistent it is ensured that the length of screw, thus increasing the length of action with threads of lead screw with screw it is ensured that leading screw is passing
Engagement distance during dynamic, it is to avoid threaded connection place is because stress is excessive or other reason leads to thread abrasion to make screw thread
The problem it is impossible to normally be driven cannot be engaged；Screw two ends are connected to first, second screw connection bump part, realize
The two ends of screw are supported it is ensured that the support strength of screw；Screw is threaded connection with screw connection bump, threaded shape
Formula can realize being reliably connected of insulating part and metalwork, in addition, the connection screw thread of screw and screw connection bump and leading screw with
To anti-, in leading screw rotation process, screw has towards the mobile trend screwing direction the rotation direction of the connection screw thread of screw, and screw is not
Get loose problem occurs；By screw connection bump using so that the internal diameter of contact body be not required to screw external diameter consistent, can
To effectively reduce the material quantity of moving contact, reduce the cost of manufacture of moving contact；The leading screw of isolation material and the screw of isolation material
Cooperation, compares leading screw directly and for the transmission of metal moving contact, it is to avoid leading screw is rubbed because moving contact rocks, and produces impact
The chip of leading screw insulating properties, also has simple and compact for structure, small volume simultaneously, safe and reliable, and stability is high, low cost and making
The advantages of use life-span length.
In other embodiments of the invention：Screw connection bump can also only include a screw connection bump part；
Screw connection bump can also be welded or is fixed in contact body by screw；First, second screw connection bump part
The two ends in contact body can be not provided with, such as be arranged at the middle part of contact body；The length of screw can also be longer than or
It is shorter than the length of contact body；Screw and leading screw can also be made using metal material, when screw and leading screw are all using metal material
When material is made, need to arrange insulated transmission part between operating mechanism and leading screw, when screw is made up of metal material, screw can
To be fixedly welded in screw connection bump；First, second screw connection bump part may not be whole loop configuration, such as
Say that first, second screw connection bump all includes the projection of circumferentially spaced setting.
The embodiment 2 of GIS device is as shown in Fig. 3 ~ 4：As different from Example 1, moving contact body adopts non-embodiment 2
Symmetrical structure, screw connection bump is only arranged at one end of moving contact body, and the other end of driven contact body is to moving contact originally
Equipped with the insulating sheath arranging with screw split, insulating sheath is fixedly arranged on the inwall of moving contact body body, insulating sheath simultaneously
Withstand in screw connection bump, such insulating sheath to moving contact inner body wall formed encapsulation protection, it is to avoid moving contact due to
Stress is excessive or other reason leads to the directly leading screw directly contact with insulation, avoids the rub chip producing and moving contact simultaneously
Body contacts and produce floating potential, further, it is to avoid that causes because of floating potential climbs electricity, protect simultaneously local put
Electricity, certainly because insulating sheath is arranged with screw split, only undertakes running part by screw, and insulating sheath is no longer used to pass
Dynamic, the selection of insulating sheath is no longer affected by transmission factor, and therefore insulating sheath can be from the more excellent material of insulating properties
Make.In other embodiments of the invention, screw connection bump can also be arranged at the two ends of moving contact body, now move and touch
Head body first need to be arranged to Split type structure, then by insulating sheath be installed to moving contact this internal after, dynamic in two Split type structures
Contact body connects into overall structure.
