Abstract
The utility model provides a supporting conductor for a high voltage isolation switch. The supporting conductor is characterized by comprising a wiring terminal (11), an outer ring (12) and an inner ring (14) both connected with the wiring terminal (11), and multiple ribbed slabs (13) connected between the inner ring (14) and the outer ring (12). The utility model also provides the high voltage isolation switch comprising the supporting conductor mentioned above.
Description
Technical field
The utility model relates to a kind of supportive conductors for high voltage isolator and this high voltage isolator.
Background technology
Along with the development in economy and power technology and market, can carry larger rated current becomes one of target that high-voltage AC switches equipment need to realize.In Chinese market, this requirement is particularly outstanding at present.High voltage isolator when realizing large rated current design, particularly in the turning junction, due to electric current skewness in conductor, can cause the too high problem of conductor temperature rise as the significant element in switchgear.Present design in this respect can't be satisfactory, especially in the design of perpendicular type supportive conductors.
The utility model content
At least one purpose of the present utility model is to provide a kind of improved supportive conductors and comprises the high voltage isolator of this conductor.
According to the utility model, a kind of supportive conductors for high voltage isolator is provided, it is characterized in that, comprise binding post, the outer shroud that is connected with described binding post, interior ring and be connected to a plurality of floors between described interior ring and described outer shroud.
In one embodiment, described a plurality of floor is evenly distributed between described outer shroud and described interior ring.
In one embodiment, described floor extending axially along described outer shroud or described interior ring.
In one embodiment, the quantity of described floor is six, eight or ten.
In one embodiment, described supportive conductors also comprises the earth terminal that is arranged on described outer shroud.
In one embodiment, described binding post, described outer shroud, described interior ring and described a plurality of rib-shaped become one.
In one embodiment, described supportive conductors is the supportive conductors of carrying out the perpendicular type switching.
This ribbed structure can make the CURRENT DISTRIBUTION that flows through supportive conductors more even, and area of dissipation is larger, can carry larger rated current, and economical with materials, and can reduce the volume of whole isolating switch.
The utility model also provides a kind of high voltage isolator, it is characterized in that, comprises aforementioned arbitrary described supportive conductors.

Fig. 5 schematically shows the stereogram according to the supportive conductors of the another kind of execution mode of the utility model.
Embodiment
Below with reference to accompanying drawing, the specific descriptions of optional execution mode of the present utility model have been provided.
As shown in Figure 1, in high voltage isolator, fixed contact 1 and moving contact 2 are via the electric connection each other of power spring 4 for example.Supportive conductors 10 can realize that for supporting moving contact 2 perpendicular type (approximately 90 °) connects simultaneously, plays effect through-flow, that support and shield.Between supportive conductors 10 and moving contact 2 via for example power spring 5 electric connections.In addition, moving contact strutting piece 3 also supportive conductors 10 is connected, and the driven unit (not shown) at the right-hand member place by being arranged on moving contact 2 drives moving contact 2 and moves left and right.When moving contact 2 is positioned at position shown in Figure 1, moving contact 2 and fixed contact 1 electric connection, thereby current lead-through.When driven unit driving moving contact 2 moved right, moving contact 2 separated with fixed contact 1, thereby turn-off current plays buffer action.
In fact, the electric current that flows through supportive conductors 10 is not equally distributed, but due to the impact that is subject to skin effect and proximity effect etc., produces inhomogeneous distribution, especially in this perpendicular type syndeton.This inhomogeneous distribution can bring problems, for example can make the local temperature of supportive conductors 10 too high.In order to make electric current more be evenly distributed on supportive conductors 10, the utility model proposes a kind of improved structure.
To shown in Figure 4, supportive conductors 10 comprises binding post 11, the outer shroud 12 that is connected with binding post 11, interior ring 14 and is connected to a plurality of floors 13 between interior ring and outer shroud as Fig. 2.Binding post 11, outer shroud 12, floor 13 and interior ring 14 can form as one.Can find by simulation, this ribbed structure makes CURRENT DISTRIBUTION more even, and area of dissipation is larger, can carry larger rated current, and economical with materials, and can reduce the volume of whole isolating switch.Binding post 11 for example can be connected with other GIS modules.
Here, for further increasing heat radiation area, can make floor 13 extending axially along interior ring 14 or outer shroud 12.Although should be appreciated that the form with equally distributed eight floors 13 schematically illustrates in Fig. 2 to 4, scope of the present utility model is not limited to this.The concrete shape of floor 13, quantity and distribution mode can be simulated and adjust according to concrete electric current demand, can be for example six floors or ten floors.
Fig. 5 illustrates the structure according to the supportive conductors of the another kind of execution mode of the utility model.Compare to structure shown in Figure 4 with Fig. 2, also be provided with earth terminal 18 on supportive conductors shown in Figure 5, be used for making supportive conductors ground connection.
Although should be appreciated that the aforementioned supportive conductors that connects with perpendicular type is described, scheme of the present utility model also can be applied to the structure that connects with other angles, and is not limited to perpendicular type.
Although illustrate and described the utility model with reference to some preferred embodiment of the present utility model, but it will be appreciated by those skilled in the art that, in the situation that do not deviate from the spirit and scope of the present utility model that limited by appended claims, can make a variety of changes it in the form and details.
