Description
Technical Field
The invention relates to the technical field of power grid equipment, in particular to a voltage divider support for direct-current buses with different structures.
Background
The +/-800 kV direct current bus voltage divider imported from abroad is a Trench RC 800-VG type voltage divider and a Schniewindow HVR-GC type voltage divider with higher operation reliability, and the two voltage dividers are made by different manufacturers and have different models. Since 2015, the conventional direct current used the Trench RC 800-VG type voltage divider frequently failed, and the Schniewind HVR-GC type voltage divider needs to be replaced on the basis of the Trench RC 800-VG type voltage divider, but the installation of the two types of voltage dividers is structurally different, mainly due to the differences in weight, height and base connection, the base of the TRENCH voltage divider is circular, and the bottom of the Schniewind voltage divider is square. The existing voltage divider support cannot meet the interchange of the voltage dividers of the two types, and great trouble is brought to maintenance and replacement.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides a voltage divider bracket which can improve the replacement efficiency and is convenient to operate and used for direct current buses with different structures.
In order to solve the technical problems, the invention is realized by the following technical scheme:
a voltage divider bracket for direct current buses with different structures comprises a bracket body, a mounting seat arranged at the lower end of the bracket body and a supporting connecting plate arranged at the upper end of the bracket body; the frame body comprises four upright posts which are distributed in a rectangular shape, a plurality of cross rods which are connected with adjacent upright posts and a plurality of diagonal braces which are connected with adjacent upright posts; the detachable chain is connected with the switching frame at the upper end of the supporting connecting plate; the switching frame comprises a lower mounting plate, a support cylinder, an upper mounting plate and a plurality of rib plates, wherein the lower mounting plate is supported on the support connecting plate and connected with the support connecting plate through bolts; the upper mounting plate is provided with a connecting hole.
Preferably, the cross bar is connected to the vertical column by a bolt.
Preferably, the diagonal brace is connected with the upright post through a bolt.
Preferably, the support connecting plate is welded to the frame body.
Preferably, the upper mounting plate is welded to the support cylinder.
Preferably, the lower mounting plate is welded to the support cylinder.
Compared with the prior art, the invention has the following advantages:
the switching module framework can be connected with a shorter Trench RC 800-VG type voltage divider base. Through switching module design structure, convenient and fast when realizing two kinds of not isostructure voltage dividers change need not wholly change basic framework, only need change switching module framework supply two kinds of model voltage dividers difference that exist on high and connection base mounting means can, reduce the degree of difficulty of changing by a wide margin.
