Intelligent copper-aluminum composite conductor bus groove

Abstract

The invention relates to an intelligent copper-aluminum composite conductor bus groove, which consists of a box body and buses, wherein the box body consists of two aluminum-magnesium alloy side plates and upper and lower aluminum-magnesium alloy cover plates; the buses are arranged in the box body and uniformly distributed between upper and lower insulating brackets at intervals; each bus is a copper-aluminum composite bus of which an outer layer is copper and an inner core is aluminum; the area of the copper section of the outer layer is 20 percent of that of the whole section; and an insulating layer is coated outside the copper-aluminum composite bus. The intelligent copper-aluminum composite conductor bus groove is simple in structure, low in impedance, low in voltage drop, low in energy consumption, low in cost and high in using reliability; a temperature monitoring system and an electric leakage monitoring system which are arranged on the bus groove can automatically detect the temperature of the bus groove during operation and the leakage current of a power supply line, perform out-of-limit alarming and guarantee the safety of a power supply system; and the bus groove is intelligent, low-cost and energy-saving and has a wide application prospect.

Description

technical field [0001] The invention belongs to power distribution equipment in the field of electric power, and relates to a bus duct, in particular to an intelligent copper-aluminum composite conductor bus duct. Background technique [0002] The rapid development of my country's electric power industry has led to a substantial increase in copper demand. The cost of copper conductors in bus ducts accounts for more than 70% of the total cost, and the price of copper has increased by more than 4 times in recent years, which has brought huge pressure to bus duct manufacturers. , forcing enterprises to reduce the conductor cross-section to deal with it, which not only reduces the safety performance of the bus duct, but also increases energy consumption. my country is poor in copper and rich in aluminum. The basic performance parameters of copper-aluminum composite conductors are close to those of copper conductors, but the cost is reduced by more than 40%. Using copper-aluminum ...
