Description
Technical field
The utility model relates to carries electric apparatus field, says it is a kind of 72.5 kilovolt of three station isolation earthing switch electrical connection device in detail.
Background technology
As everyone knows: the gas insulated metal enclosed swit chgear isolation earthing switch is regenerated through bringing in constant renewal in, product develops towards simple, convenience, safety, integration direction, three station isolation earthing switch are also more and more had an optimistic view of by the user with it self advantage, but the conductive component complex structure of isolation earthing switch the inside, relatively harsher to installation requirement, difficult for the overall performance control ratio of switch; Originally the fingertip of Cai Yonging is the flap fingertip, because the demand of ampacity, the structure that electrically connects is huger, and is bigger for the barrel space dimensional requirement of switch, has restricted isolation earthing switch and has developed to the direction of oversimplifying miniaturization.
Summary of the invention
The purpose of this utility model just is to overcome the deficiency of existing technology, a kind of three station isolation earthing switch electrical connection devices are provided, simple in structure, easy for installation, satisfying under the situation of rated current, the overall structure that electrically connects is compact more, profile is littler, has saved the inner space of isolating switch, and the reliability that electrically connects is higher.
The utility model adopts following technical solution: a kind of three station isolation earthing switch electrical connection devices, be provided with the four-way cylindrical shell, ground connection cover plate and disk insulator are fixed by bolts to respectively on the four-way cylindrical shell, ground connection Electricity Federation bar is by being bolted on the ground connection cover plate, isolate the Electricity Federation extension bar by being bolted on the disk insulator, rotate extension bar centre, Electricity Federation and be connected as a single entity by rotating shaft, the rotating shaft two ends link to each other with bearing by bearing, rotating shaft is connected as a single entity three-phase conductor by rotating insulator, link to each other through rotating insulator between driving shaft and the rotating shaft, ground connection Electricity Federation extension bar, rotate the Electricity Federation extension bar, isolate on the extension bar of Electricity Federation and have watchband fingertip mounting groove, multiconductor formula watchband fingertip is housed in the watchband fingertip mounting groove, and rotation Electricity Federation extension bar is vertical with ground connection Electricity Federation extension bar and isolation Electricity Federation extension bar respectively.
The beneficial effects of the utility model are, and are simple in structure, easy for installation, satisfying under the situation of rated current, and the overall structure that electrically connects is compact more, and profile is littler, has saved the inner space of isolating switch, and the reliability that electrically connects is higher.
