Body is related to a kind of three position mechanism positioning switching device.
[background technique]
Three-station mechanism is usually used in fully closed combined electric unit or compound electric apparatus, is usually used in XGN ring network cabinet.It is so-called
Three stations refer to three operating positions: (1) closing position that main fracture of isolating switch is connected；(2) the separated isolated bit of main fracture
It sets；(3) earthing position of ground side.
Traditional three-station is exactly to incorporate the function of both disconnecting switch and earthing switch in fact, and by a knife
Complete, mechanical latching thus may be implemented, prevent major loop electrification from closing earthing knife-switch because one knife can only a position,
And not as traditional disconnecting switch, operator is operator, and earthing knife-switch is earthing knife-switch, may go out maloperation between two knives.And three stations
Disconnecting switch is a knife, and it is not in main switch closing position, just that one, which the operating position of knife is at a time unique,
It is in isolated location or earthing position.In traditional GIS, disconnecting switch and earthing switch are two functional units, using electrical
Interlocking is controlled.
When traditional three position mechanism operation can only double-throw contact simultaneously, cannot be touched in designated position Pre-handoff part
Point.

Changing device, it realizes Pre-handoff contact using the closure of microswitch；It has it is easy to use, it is fixed using three position mechanism
Position switching improves work efficiency to realize Pre-handoff part contact.
A kind of three position mechanism described in the utility model positions switching device, it includes positioning switching device ontology, should
Positioning switching device ontology includes pivot pin, screw one, stop screw two, mounting plate, microswitch, switching connecting lever；
The mounting plate is mounted on three position mechanism machine core；The shape of the mounting plate is L shape；The microswitch
It is mounted in the vertical plate body of mounting plate；The left end of the horizontal plate body of the mounting plate is equipped with switching connecting lever, passes through screw one
Hingedly on a mounting board and switching connecting lever can be rotated automatically around screw one；On the mounting plate, switch the horizontal component of connecting lever
Stop screw two is provided with above right-hand end；The pivot pin is mounted on three position mechanism machine core, the vertical brake on the left of mounting plate
In road.
Further, the shape of the switching connecting lever is L shape, and the horizontal component length of the switching connecting lever is slightly shorter than mounting plate
The height of the width of vertical plate body, the vertical component of the switching connecting lever is higher than microswitch, switches connecting lever to inward side to rotation
When, it can touch to microswitch.
Further, the microswitch is the model PS056- of Boluo Shiwan Dike Electronics Co., Ltd.'s production
The microswitch of 01N-200.
After adopting the above structure, the utility model has the beneficial effect that a kind of three position mechanism described in the utility model is fixed
Position switching device, it realizes Pre-handoff contact using the closure of microswitch；It has it is easy to use, utilize three station machines
Structure positioning switching improves work efficiency to realize Pre-handoff part contact.

[specific embodiment]
Be described in detail the utility model below in conjunction with attached drawing and specific embodiment, illustrative examples therein with
And explanation is only used to explain the utility model, but is not intended to limit the scope of the present invention.
As shown in Figure 1-Figure 3, a kind of three position mechanism positioning switching device described in present embodiment, it includes fixed
Position switching device ontology, the positioning switching device ontology include that pivot pin 1, screw 1, stop screw 23, mounting plate 4, fine motion are opened
Close 5, switching connecting lever 6；
The mounting plate 4 is mounted on three position mechanism machine core 7；The shape of the mounting plate 4 is L shape；The fine motion
Switch 5 is mounted in the vertical plate body of mounting plate 4；The left end of the horizontal plate body of the mounting plate 4 is equipped with switching connecting lever 6, leads to
Crossing screw 1 and being hinged on mounting plate 4 and switch connecting lever 6 can rotate automatically around screw 1；On the mounting plate 4, switching is turned
Stop screw 23 is provided with above the horizontal component right-hand end of arm 6；The pivot pin 1 is mounted on three position mechanism machine core, installation
In the vertical gate 8 in 4 left side of plate.
Further, the shape of the switching connecting lever 6 is L shape, and the horizontal component length of the switching connecting lever 6, which is slightly shorter than, to be installed
The width of 4 vertical plate body of plate, the height of the vertical component of the switching connecting lever 6 are higher than microswitch 5, and switching connecting lever 6 is to inward side
To when rotation, can touch to microswitch 5.
Further, the microswitch 5 is the model PS056- of Boluo Shiwan Dike Electronics Co., Ltd.'s production
