Abstract
The utility model discloses a bottom-housing for a gas insulation vacuum switch. The bottom housing is provided with three-phase terminal pillars, all located on the same arc. The utility model makes improvements and modifications to the present bottom housings for gas insulation vacuum switches by arranging the three terminal pillars on the same arc and separating the wires in the center of the circle. Each of the separated three wires has an equal distance to the terminal pillar it is connected thereto. Consequently, without adjusting the length of a wire, the wire can still be conveniently and swiftly connected to a terminal pillar.
Description
Technical field
The utility model relates to the gas-insulated vacuum switch, relates in particular to a kind of housing of gas-insulated vacuum switch.
Background technology
The gas-insulated vacuum switch generally includes and is sealed with sulphur hexafluoride (sf
6) housing of gas, housing is made up of upper shell and lower house, is provided with three-phase isolation switch and earthed switch in this housing, is connected with vacuum outside upper shell, outside lower house, be connected with three cable connection posts, be connected respectively to the threephase switch in the housing.When the cable of outside need be connected on these three binding posts, cable skin must be cut, three strands of electric wires of its parcel respectively by three binding posts that are sequentially connected to of three-phase, because three cable connection posts generally are triangularly arranged or linear array, cause the distance of three strands of electric wire to three binding posts and unequal, must select again each strand electric wire cut off and to receive on the binding post smoothly after adjusting length.But the cable that is used for this kind gas-insulated vacuum switch is very thick and heavy, and is very difficult time-consuming when the workman operates.
Summary of the invention
At the shortcoming of prior art, the purpose of this utility model provides a kind of lower house of gas-insulated vacuum switch, and the troublesome operation when having solved wiring has been saved the time.
To achieve these goals, the technical solution of the utility model is: a kind of lower house of gas-insulated vacuum switch, on this lower house, be provided with the three-phase binding post, and every binding post all is positioned on the same circular arc.
About two binding posts equate to the distance of indirect terminal.
Described lower house is rectangular shape, vertically is connected with an ennation below this lower house, and described binding post is arranged on this prolongation housing.
Equidistantly be provided with three phase holes on the base plate of described lower house inside along its length, these three phase holes link to each other with three binding posts respectively, and the horizontal stripe with projection between each phase hole separates.
Described horizontal stripe is close to prolong on the madial wall of described lower house a bit of triangular in shape.
Compared with prior art, the utility model has carried out improving design to the lower house of gas-insulated vacuum switch, three cable connection posts of lower house all are arranged on the same circular arc, at its circle centre position cable is separated, its three strands of electric wires telling equate to the distance of each corresponding binding post, needn't be again can be connected on the binding post the length adjustment of electric wire, convenient fast.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation one of the present utility model.
Fig. 2 is a structural representation two of the present utility model.
Fig. 3 is a structural representation three of the present utility model.
Embodiment
Seeing also Fig. 1, Fig. 2 and Fig. 3, is respectively the structural representation of the utility model under different visual angles.The lower house 1 of the gas-insulated vacuum switch of present embodiment is rectangular shape, below this lower house, vertically be connected with an ennation 2, on this prolongation housing, be provided with three-phase binding post 3, every binding post all is positioned on the same circular arc, and about two binding posts equate to the distance of indirect terminal.On the base plate of lower house inside, equidistantly be provided with three phase holes 4 along its length, these three phase holes link to each other with three binding posts respectively, horizontal stripe 5 with two groups of projections between each phase hole separates, every group has three horizontal stripes, this kind structure can strengthen the creepage distance between each phase, thereby make the gas-insulated vacuum switch realize miniaturization, satisfy the economic needs of enterprise; Horizontal stripe is close to prolong on the madial wall of lower house a bit of triangular in shape, prevents that further electric arc from walking around from sidewall.
Though the present invention discloses as above with a preferred embodiment, is not in order to limit scope of the invention process.Any those of ordinary skill in the art, promptly every when doing a little improvement in not breaking away from invention scope of the present invention according to the equal improvement that the present invention did, should be invention scope of the present invention and contain.
