Improved Design of Fuse Tube for Environmental Protection Cabinet Based on Electric-Field Simulation

چکیده
Since the insulation performance of air is not as good that SF6 and other gases, it necessary to conduct an in-depth study on characteristics fuse tube in order meet requirements normal breaking design a structural improvement scheme for 12 kV environmental protection cabinet suitable using insulating medium. In this study, before was studied, electric-field distribution placed air-insulated switchgear analyzed. The results showed heavily concentrated gap plug around ground rod. structure specifically designed. By spraying conductive paint intersection surface different media, equipotentiality achieved, reasonable metal shielding added site where field intensity so improve avoid breakdown caused by concentration intensity. Through several improved designs, maximum strength can be effectively reduced, relevant standards met. A partial discharge test carried out, local quantity met industry requirements, which verified rationality fuse-tube-improvement scheme.

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
Stiffness-based Approach for Preliminary Design of Framed Tube Structures
A parametric formulation for preliminary design of tubed-system tall buildings is presented in which some optimality criteria and practical constraints are considered. Here, a minimum compliance optimization formulation, developed by other researchers, is applied to a framed-tube structure. The tube behavior is modeled as a cantilevered box beam. Independent variable in this problem is thicknes...
