A voltage divider support for DC buses with different structures

Abstract

The present invention discloses a voltage divider bracket used for direct current buses with different structures. The bracket is aimed at providing the easily-operated voltage divider bracket used for direct current buses with different structures. The bracket comprises a bracket body, mounting seats arranged on the lower ends of the bracket body, and a supporting and connecting plate arranged onthe upper end of the bracket body. The bracket body comprises four rectangularly-distributed upright columns, multiple transverse rods connecting the adjacent upright columns, and multiple oblique support rods connecting the adjacent upright columns. The bracket body also comprises a transferring bracket connected with the upper end of the supporting and connecting plate via detachable chains. The transferring bracket comprises: a lower-part mounting plate, wherein the lower-part mounting plate supports on the supporting and connecting plate, and the lower-part mounting plate is connected with the supporting and connecting plate via screw bolt(s); a support cylinder arranged at the middle of the upper end of the lower-part mounting plate; an upper-part mounting plate arranged on the upperend of the support cylinder; and multiple stiffened plates, wherein the stiffened plates are arranged on the outer wall of the support cylinder, and each stiffened plate is separately connected withthe lower-part mounting plate and the upper-part mounting plate. The upper-part mounting plate is provided with connection holes. The bracket can effectively improve the maintenance efficiency of thedirect current buses.

Description

technical field [0001] The invention relates to the technical field of power grid equipment, in particular to a voltage divider bracket used for DC buses with different structures. Background technique [0002] Among the ±800kV DC bus voltage dividers imported from abroad, Trench RC 800-VG and Schniewindt HVR-GC voltage dividers are more reliable in operation. These two voltage dividers have different manufacturers and models. Since 2015, the Trench RC 800-VG voltage divider used by Puqiao DC has frequently failed. It is necessary to replace the Schniewindt HVR-GC voltage divider on the basis of the Trench RC 800-VG voltage divider. However, due to the two types of voltage dividers The structure of the divider is different when it is installed, mainly in the difference in weight, height and base connection. The base of the TRENCH voltage divider is round, while the bottom of the Schniewindt voltage divider is square. However, the existing voltage divider support cannot meet...
