Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in further detail.
The present embodiment is as a example by ± 1100kV direct-current wall bushing insulation test device, and as shown in Figures 1 to 4, the present invention implements
Example provide ± 1100kV direct-current wall bushing insulation test device includes: direct-current wall bushing 1, metal fixing plate 2, simulation
Body of wall 3, bracing frame 4, base 5, adpting flange 6, angle regulator 7, metal rotating shaft 8, U-shaped regulation support 9, U
Type pedestal 10, regulation rocking bar 11, angle dial gauge 12, turbine worm decelerator 13.
In the middle part of direct-current wall bushing 1, adpting flange 6 is installed in outside, by adpting flange 6, direct-current wall bushing 1 is installed on gold
Belong in the circular hole in the middle part of fixed plate 2.As in figure 2 it is shown, metal fixing plate 2 is respectively arranged on the left side and the right side corresponding metal rotating shaft
8, metal rotating shaft 8 is inserted in the U-shaped regulation support 9 of angle regulator 7, thus realizes direct-current wall bushing 1 and angle
The docking of adjusting means 7.Angle regulator 7 includes U-shaped regulation support 9 and U-shaped pedestal 10, U-shaped regulation support 9
Inside arranges turbine worm decelerator 13, as it is shown on figure 3, one end of turbine worm decelerator 13 is connected with regulation rocking bar 11,
The other end is then connected with metal rotating shaft 8.Turbine worm decelerator 13 action is driven so that turbine by rotating regulation rocking bar 11
Scroll bar decelerator 13 drives direct-current wall bushing 1 to rotate by metal rotating shaft 8, the angle of inclination of direct-current wall bushing 1 between ±
Between 75 °, it is achieved the angular adjustment of direct-current wall bushing 1.Meanwhile, turbine worm decelerator 13 has auto-lock function, when directly
Flowing through wall sleeve 1 when rotating to certain angle, stop the rotation to regulation rocking bar 11, turbine worm decelerator 13 is locked the most automatically
Extremely, thus realize that direct-current wall bushing 1 rotates to during certain angle fixing.Go back setting angle on U-shaped regulation support 9 simultaneously
Dial gauge 12, as shown in Figure 4, the pointer within angle dial gauge 12 is connected with metal rotating shaft 8, when direct-current wall bushing 1
When being in level, pointer is in by-level zero point, when direct-current wall bushing 1 is rotated by metal rotating shaft 8,
Metal rotating shaft 8 will drive indicators turn, and therefore, the angle that direct-current wall bushing 1 rotates can be directly by angle dial gauge 12
The deflection angle of pointer represents.
U-shaped regulation support 9 is vertically fixed on the top of bracing frame 4 by U-shaped pedestal 10, and simulation body of wall 3 is positioned at angle and adjusts
The outside top being the most vertically fixed on bracing frame 4 of regulating device 7, simulation body of wall 3 is aluminum metal sheets, lighter in weight, convenient examination
Test process and the installation of later maintenance and dismounting.Bracing frame 4 is built with tower-type structure by metal steel, has stronger
Stability and weight capacity, be vertically fixed on bottom it on support base 5.
This assay device for the design of ± 1100kV direct-current wall bushing, the insulating properties of package unit meet ± 1100kV and with
Lower grade wall bushing assay device insulating requirements, can effectively solve the problem that support problem fixed by large-sized DC wall bushing simultaneously, full
Foot ± 1100kV direct-current wall bushing Insulation Test requirement.On the other hand, this assay device possesses angle regulating function, it is possible to change
Become sleeve pipe and ground connection body of wall angle, thus simulate the impact on wall bushing Insulation Test of the actual different installation, it is possible to more
Grasp the insulation characterisitic of direct-current wall bushing all sidedly.
Finally should be noted that: above example is only in order to illustrate that technical scheme is not intended to limit, although reference
The present invention has been described in detail by above-described embodiment, those of ordinary skill in the field it is understood that still can to this
Invention detailed description of the invention modify or equivalent, and without departing from spirit and scope of the invention any amendment or etc.
With replacing, it all should be contained in the middle of scope of the presently claimed invention.
