Abstract
The utility model relates to a kind of direct action type three-station with guiding trestle, including operating mechanism, grounding base, middle base, inlet wire seat, insulation rotating shaft and moving contact, described grounding base, middle base and inlet wire seat conllinear, interval are arranged, it is provided with guiding trestle between described middle base and inlet wire seat, described guiding trestle offers moving contact perforation.Even if the utility model gas tank deforms, three-station moving contact also can reach closing position exactly from isolated location, it is ensured that three-station long-time steady operation.
Description
Technical field
The utility model relates to the tri-station isolating switch technical field of middle pressure box type gas insulating switchgear, specifically public
Open a kind of direct action type three-station with guiding trestle.
Background technology
The tri-station isolating switch of middle pressure box type gas insulating switchgear (C-GIS) commonly uses a kind of Direct Action Type three work
Bit switch (such as Fig. 1)；Direct action type three-station is by the inlet wire seat in gas tank, middle base, grounding base, moving contact, insulation rotating shaft
Part composition, also has the operating mechanism that operation rotating shaft rotates outside gas tank.
This three-station is arranged in metal gas tank, and three-station parts are by insulating part or are directly installed on
On gas tank sidewall.
Moving contact is arranged in insulation rotating shaft, and operating mechanism rotates as required, drives moving contact to move, it is achieved three
Plant different on off states (combined floodgate, isolation, ground connection).
Gas tank can because many factors impact be deformed: the 1st, switchgear in running owing to electric current passes through conductor
And generate heat, make Peng that is heated of insulating gas in gas tank rise；2nd, height above sea level raises；3rd, switchgear ambient temperature changes greatly；Gas
The deformation of case can bring direct action type three-station (from isolated bit to closing position) moving contact when closing a floodgate can not enter inlet wire seat
Interior situation (such as Fig. 2), the normal work of impact.
Utility model content
Goal of the invention of the present utility model is: even if providing a kind of gas tank deformation for solving problem above, three stations are opened
Close moving contact and also can reach the direct action type three-station with guiding trestle of closing position exactly from isolated location.
The utility model be employed technical scheme comprise that such:
A kind of direct action type three-station with guiding trestle, including operating mechanism, grounding base, middle base, inlet wire seat, absolutely
Edge rotating shaft and moving contact, described grounding base, middle base and inlet wire seat conllinear, interval are arranged, between described middle base and inlet wire seat
It is provided with guiding trestle, described guiding trestle offers moving contact perforation.
Further, described guiding trestle is made up of insulating materials.
Further, described guiding trestle is installed on gas tank inner panel.
In sum, owing to using technique scheme, the beneficial effects of the utility model are:
Even if the utility model is in the case that gas tank deforms, three-station moving contact energy in the guiding of guiding trestle
Enough enter precisely in inlet wire seat, it is ensured that three-station long-time stable works.
Brief description
Fig. 1 is prior art construction figure；
Fig. 2 is the condition diagram that prior art construction moving contact can not enter in inlet wire seat；
Fig. 3 is the utility model structural representation；
Fig. 4 is guiding support structure figure described in the utility model.
Detailed description of the invention
With embodiment, the utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 3-4, a kind of direct action type three-station with guiding trestle, including operating mechanism the 1st, grounding base the 2nd, in
Between seat the 3rd, inlet wire seat the 4th, insulate rotating shaft 5 and moving contact 6, described grounding base the 2nd, middle base 3 and inlet wire seat 4 conllinear, interval are arranged,
It is provided with the guiding trestle 7 being made up of insulating materials between described middle base 3 and inlet wire seat 4, described guiding trestle 7 offers dynamic
Contact 6 is bored a hole；Described guiding trestle 7 is installed on gas tank inner panel.
Even if the utility model is in the case that gas tank deforms, moving contact 6 can be exactly in the guiding of guiding trestle 7
Enter in inlet wire seat 4.
Describe know-why of the present utility model above in association with specific embodiment.These descriptions are intended merely to explain this reality
By novel principle, and the restriction to the utility model protection domain can not be construed to by any way.Based on explanation herein,
Those skilled in the art does not needs to pay performing creative labour can associate other detailed description of the invention of the present utility model,
These modes fall within protection domain of the present utility model.
