Abstract

The invention relates to a tubular busbar system and a tubular busbar installation parameter determination method. The tubular busbar system comprises a plurality of tubular busbars and a plurality ofconnecting devices connected with the tubular busbars, wherein the maximum allowable span of the tubular busbar is determined according to a three-phase short-circuit current peak value, a phase-to-phase distance, a vibration coefficient, an internal force coefficient, a wind speed non-uniform coefficient, an aerodynamic coefficient, a busbar conductor outer diameter, tubular busbar dead weight,tubular busbar icing weight, a tubular busbar section coefficient and 50% of maximum wind speed during short circuit. According to the embodiment of the invention, the problem of poor reliability of an existing tubular busbar can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of electrical connection devices, and in particular to a tubular busbar system and a method for determining installation parameters of the tubular busbar. Background technique [0002] As a large current transmission equipment, solid insulated tubular busbars have been gradually and widely used in substations and power transmission and transformation lines. [0003] At present, the installation of solid-insulated tubular busbars is based on the actual situation on site, and the manufacturer installs them by themselves after surveying and mapping based on the actual site conditions. After the busbar is installed, environmental factors such as foundation conditions, climate and ambient temperature, and seismic activity are more complicated. The layout of the tubular busbar often leads to hidden dangers in the fixing of the tubular busbar due to improper selection of fixing methods or poor design consi...
