Spacing rod used for erecting high-voltage bus

Abstract

The present invention provides a spacing rod used for erecting a high-voltage bus, and relates to the electric power engineering field. The spacing rod used for erecting the high-voltage bus comprises a rod body, a top plate is fixedly connected at the top of the rod body, and a fixing plate is in lap joint with the upper surface of the top plate. An upper snap ring is fixedly connected at the right side of the fixing plate, the bottom of the upper snap ring is in lap joint with the upper surface of the top plate, and the upper surface of the fixing plate is equipped with an open hole communicated with the lower surface. A screw is in threaded connection inside the open hole, and the upper surface of the top plate is equipped with a screw hole communicated with the lower surface. According to the spacing rod used for erecting the high-voltage bus, by using the upper snap ring to drive a clamping block to be inserted in a groove, an effect of increasing the clamping degree of the upper snap ring to the high-voltage bus is realized; by the mutual cooperation of the screw, the fixing plate and the top plate, the effect that the screw fixes the fixing plate and the top plate mutually, at the same time, fixes the upper snap ring, is realized; and by sliding a sliding block rightwards, an effect that a first snap ring and a second snap ring clamp the high-voltage bus, is realized.

Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a spacer bar for erecting a high-voltage bus. Background technique [0002] Two, four or more split conductors are used for each phase conductor of the long-distance and large-capacity high-voltage transmission bus. At present, 220KV and 330KV transmission lines use two-split conductors, 500KV transmission lines use three-split and four-split conductors, and ultra-high voltage transmission lines with voltages higher than 500KV use six-split and more split conductors. In order to ensure that the distance between the split wire harnesses remains unchanged to meet the electrical performance, reduce the surface potential gradient, and in the case of a short circuit, the electromagnetic force will not be generated between the wire harnesses, causing mutual attraction and collision, or even if the instantaneous attraction collision is caused, but after the accident i...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a spacer bar for erecting a high-voltage busbar, which solves the problem that the existing spacer bar is inconvenient to adjust the length, so workers must use the spacer bar that is matched with the wire when installing the spacer bar. Such an installation method Not only will it reduce the practicability of the spacer, but it will also affect the construction of the workers, resulting in the problem that the construction period is extended
