Description
Technical field
The utility model relates to switching device, relates in particular to a kind of isolation switch device of three station Omnibearing visuals.
Background technology
In the prior art, the position of the isolating switch moving contact in solid insulation ring main unit can not be directly visual, can only indirectly indicate by the action of operating mechanism or pull bar, cause operating maintenance personnel can not judge reliably the operating state of isolating switch, when the instruction of mechanism or pull bar and the physical location of isolating switch moving contact are inconsistent time, probably will therefore produce security incident.
At present, have producer to place visible observation window in solid cabinet insulating cylinder front, but operating maintenance personnel can only see some stations of isolating switch, in the process of power-off, maintenance, power transmission, can not understand all sidedly the operating state of isolating switch.The scheme that Ye You producer adopts vacuum switch tube and isolating switch to distribute up and down, be provided with observation window in insulating cylinder front, rear side is installed one by the fixing arc transparent cover plate of nut inserts, there is the risk of insulation breakdown in the scheme of this secondary seal, and cupboard while normally moving the moving contact of isolating switch nestle up the observation window in insulating cylinder front as electrified body, band electrical distance cannot meet security needs, there is very large danger, and adopt the moving contact pull bar of this scheme isolating switch towards bottom of cabinet, the operation of isolating switch is inevitably placed in bottom of cabinet, bring numerous inconvenience to operating maintenance personnel's work, especially under some above-mentioned extreme cases, just likely cause danger, even cause large security incident.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, provides a kind of isolation switch device of three station Omnibearing visuals.
Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of isolation switch device of three station Omnibearing visuals, it is characterized in that: comprise insulating cylinder, vacuum switch tube, movable contact block, fixed contact, moving contact, fracture contact and grounding contact, described vacuum switch tube is arranged on the inner rear side of insulating cylinder, described movable contact block is fixed on bottom, insulating cylinder front side, movable contact block connects moving contact, fracture contact is fixed on directly over movable contact block, and fixed contact and grounding contact distribute in the bilateral symmetry of movable contact block; Described vacuum switch tube is connected with fixed contact by being flexible coupling; Described insulating cylinder front is provided with transparent windows.
Further, the top of described insulating cylinder is provided with LED illuminating lamp, for insulating cylinder interior lighting provides light source.
Further, described grounding contact is arranged on observation window one side.
Isolating switch of the present utility model is arranged on the insulating cylinder inside of once-forming, does not have the risk of secondary seal, near observation window be the earthing position of this isolating switch, effectively ensured safety, and its three service positions can be directly visual.
The utility model advantage is compared with prior art: isolating switch of the present utility model is arranged on the insulating cylinder inside of once-forming, there is not the risk of secondary seal, near observation window is the earthing position of this isolating switch, effectively ensured safety, and its three service positions can be directly visual.

Fig. 2 is the schematic diagram of isolating switch at closing position.
Fig. 3 is the schematic diagram of isolating switch at open position.
Fig. 4 is the schematic diagram of isolating switch at earthing position.
In figure: 1-insulating cylinder, 2-vacuum switch tube, 3-is flexible coupling, 4-fixed contact, 5-moving contact, 6-movable contact block, 7-fracture contact, 8-grounding contact, 9-transparent windows, 10-LED illuminating lamp.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figures 1 to 4, the full visual isolation switch of three station described in the utility model is arranged on the inner front side of solid insulation ring main unit insulating cylinder 1, vacuum switch tube 2 is arranged on the inside rear side of insulating cylinder 1, 3 be connected with fixed contact 4 by being flexible coupling, importantly: movable contact block 6 is fixed on the bottom of insulating cylinder 1, fixed contact 4 distributes in the bilateral symmetry of movable contact block 6 with grounding contact 8, grounding contact 8 is arranged on observation window 9 one sides, fracture contact 7 movable contact block 6 directly over, when moving contact 5 is vertical, be that isolating switch is in sub-gate position, moving contact 5 under the driving of isolator operating mechanism along some rotation on movable contact block 6, respectively with fixed contact 4, fracture contact 7, grounding contact 8 contacts respectively, form and close a floodgate, separating brake, the transformational structure of ground connection three stations, movable contact block 6 is not because can cause obstruction to people's sight line in bottom, be provided with the transparent windows 9 of the moving contact station state for observing tri-station isolating switch in the front of insulating cylinder 1, the co-bit of isolating switch, divide position, ground connection position and observation window are almost in one plane, all contacts of isolating switch are exposed under observation window completely, this design makes the service position of observing isolating switch moving contact from front become possibility, operating maintenance personnel can be according to the moving contact 5 and fixed contact 4 seen, the contact situation of fracture contact 7 or grounding contact 8, judge intuitively the service position of isolating switch and the integrality of contact, and grounding contact 8 is arranged on the side near observation window 9, electrified body is spaced out effectively, effectively ensure operating maintenance personnel's safety.
In order further to strengthen observing effect, in this programme, be provided with LED illuminating lamp 10 at the top of insulating cylinder 1, for insulating cylinder 1 interior lighting provides light source.
Above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised to scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; As long as any being equal to done according to spirit that this patent discloses changes or modify, all fall into the scope that this patent comprises.
