Abstract
The utility model discloses a line-shaped rapid grounding switching device. The line-shaped rapid grounding switching device comprises a housing. The housing internally comprises a bearer, a transmission mechanism, a moving contact and a connector base, wherein the transmission mechanism is connected with the moving contact, the moving contact is arranged in the shape of a line and is correspondingly sleeved in the connector base, and the transmission mechanism comprises a support, a rotation shaft, a connecting lever and a connecting rod. According to the utility model, the rotation of the rotation shaft dials the connecting lever to correspondingly rotate, and the connecting lever and the connecting rod are fixed together so as to drive the support to perform upwards or downwards linear motion under the limiting of the connector base and accordingly drive the moving contact connected with the support to perform linear motion, enabling the switching device to realize switching-off and switching-on. Since an insulation basin is eliminated, the size is smaller, and the material cost is saved; the spring contact connection between the moving contact and the connector base not only can satisfy stable contact point and contact force, but also can reduce operation power to the maximum; and the moving contact is arranged in the shape of a line so that the electric field inside the housing is more uniform, and the device reliability is improved.

Background technology
Quick ground switch device is an assembly of Cubicle Gas-Insulated Switchgear, be configured in the outgoing line interval switch of transmission line circuit by circuit one side, it has two effects: folding parallel aerial circuit is due to the capacitance current of electrostatic induction generation and the inductive current of electromagnetic induction generation; When creepage phenomenon or enclosure arcing appear in enclosure insulator, high speed grounding switch, by major loop rapid grounding, utilizes circuit breaker excision fault current.
Existing high speed grounding switch have three-phase separate box with two kinds of technical schemes of Threephase common-box.Three-phase separate case structure is complicated, closes in process frictional resistance larger, and the operating work of mechanism is had relatively high expectations, and this structure need adopt flat raft to arrange in addition, and floor space is larger, build drop into larger.
Threephase common-box has two kinds of mentalities of designing, a kind of is " in-line " high speed grounding switch, connection in existing this technology between moving contact and conducting rod realizes by busbar and soft copper band, during Quick ground switch device divide-shut brake, soft copper band is due to reciprocating motion, there will be to fall copper scale, the phenomenon even fractureing, the security reliability of switch is inadequate; Another kind is " isosceles triangle " high speed grounding switch, this high speed grounding switch complex structure, during folding, by guide rail, lead, centering requirement to part is very high, when itself and tri-station isolating switch are used in conjunction with, separates for separate switch element between the two by disc insulator, and high speed grounding switch can not vertical duction, such structure is not only installed inconvenience, and makes the connecting mode of tri-station isolating switch cannot flexible arrangement, and the cost of whole device is higher.
Summary of the invention
For the existing above-mentioned technical problem of prior art, the utility model provides a kind of in-line Quick ground switch device, and its moving contact is " one " font and arranges, Electric Field Distribution is more even, simple and compact for structure, without fall the sorrow of bits because of wearing and tearing, insulation safety is reliable.
An in-line Quick ground switch device, comprises housing, includes bearing, transmission mechanism, moving contact and junction block in described housing; Described transmission mechanism is connected with moving contact, and described moving contact is that in-line is arranged and correspondence is sheathed in junction block.
Described transmission mechanism comprises:
Support, it is connected with moving contact;
Rotating shaft, its one end and housing are rotationally connected, and the other end is connected with bearing;
Connecting lever, it is installed in rotating shaft;
Connecting rod, its one end is connected with connecting lever, and the other end is connected with support.
Described housing is provided with grounding base, and described grounding base is connected with junction block by busbar; Guarantee stable electrical connection, improved the reliability of device.
In described housing, also comprise flange, described junction block is located on flange.
Preferably, described junction block is connected with moving contact by spring contact; To have guaranteed have stable contact point and contact force, again very large reduction frictional resistance, reduced the operating work of device.
Described housing adopts cast aluminium.
The utility model rotates by rotating shaft, and then stir the corresponding rotation of connecting lever, connecting lever and connecting rod are fixed together, thereby drive support to do rectilinear motion up or down under junction block spacing, thereby drive the moving contact joining with support to do rectilinear motion, make Three-phase common-box type high-speed grounding switching device realize separating brake or combined floodgate.
The utility model device is owing to having removed insulating basin, and volume is less simultaneously, has saved material cost; Owing to adopting single guiding bar linkage structure in parallel, increased the accuracy of motion simultaneously; Its joint link lever Structure Improvement mechanically operated reliability, guaranteed the accuracy closing; Between moving contact and junction block, adopt spring contact to connect and both can meet stable contact point and contact force, can maximum possible reduce actuating merit again, moving contact is " one " font to be arranged, and the electric field of enclosure interior is more even, has improved the reliability of device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that Fig. 1 is along the profile of AA line direction.
Embodiment
In order more specifically to describe the utility model, below in conjunction with the drawings and the specific embodiments, the technical solution of the utility model is elaborated.
As depicted in figs. 1 and 2, a kind of in-line Quick ground switch device, comprises housing 1, includes bearing 11, transmission mechanism, flange 4, moving contact 6 and junction block 5 in housing 1, and housing 1 is provided with grounding base 2; Transmission mechanism is connected with moving contact 6, and moving contact 9 is that in-line is arranged and correspondence is sheathed in junction block 5.
Transmission mechanism comprises support 10, rotating shaft 7, connecting lever 8 and connecting rod 9; Wherein: one end of rotating shaft 7 is connected with housing 1 inner rotation, the other end is connected with bearing 11, on connecting lever 8, rod connection point is set, connecting rod 9 is for machining in pairs, and connecting rod 9 two ends are connecting respectively connecting lever 8 and support 10, by the balanced transmission mechanism of connecting rod 9, moved, moving contact 6 is fixedly connected with support 10, and support 10, under junction block 5 is spacing, drives moving contact 6 to do rectilinear motion, three junction blocks 5 are fixed on flange 4, and three busbars 3 are fixed between corresponding junction block 5 and grounding base 2.
Housing 1 is monolithic construction, and it adopts monoblock cast processing technology.
The moving contact 6 that support 10 connects is placed in junction block 5, so guaranteed the position degree of moving contact 6 simultaneously.
