Single dual-circuit bus duct capable of combining bus and cable

Abstract

The invention relates to a single dual-circuit bus duct capable of combining a bus and a cable. The single dual-circuit bus duct comprises a shell, wherein a busbar accommodating space on the upper part and a cable accommodating space on the lower part are formed in the shell; multiple busbar conductors are arranged in the busbar accommodating space; the multiple busbar conductors are electricallyinsulated by insulating and phase-separating blocks; and multiple cables are arranged in the cable accommodating space. The bus duct provided by the invention combines the busbar conductors capable of forming a power circuit and the cables capable of forming an illumination circuit in the single shell, so that the bus duct is particularly suitable for occasions needing power and illumination distributing lines at the same time, such as an industrial factory building and a track traffic tunnel.

Description

technical field [0001] The invention relates to a bus duct; more specifically, the invention relates to a double-circuit bus duct combining bus bars and cables. Background technique [0002] In industrial automation factories and traffic tunnels, it is necessary to configure power and lighting power at the same time. In the past, in various power occasions including industrial automation factories and rail transit tunnels, cables were usually used (for simplicity, the present invention The wires and cables are collectively referred to as cables) to transmit power and lighting electricity. This power supply method has the following problems: [0003] 1. The service life of the cable is only 18-25 years, and the cost of replacement in the middle is very high; [0004] 2. Since the power cable is laid in the same groove as the lighting cable, it involves heat dissipation, and the carrying capacity is difficult to guarantee; [0005] 3. A short circuit in the cable power suppl...

AI Technical Summary

Problems solved by technology

[0003] 1. The service life of the cable is only 18-25 years, and the cost of replacement in the middle is very high;

[0004] 2. Since the power cable is laid in the same groove as the lighting cable, it involves heat dissipation, and the carrying capacity is difficult to guarantee;

[0005] 3. A short circuit in the cable power supply is likely to cause a fire accident, and a problem with a certain line will also affect the safety of other lines;

[0006] 4. When the cables are laid alone in the tunnel, they are messy and unsightly

[0007] Although with the rapid development of industrial automation and rail transit in my country in recent years, more and more bus ducts are used for power transmission and distribution in industrial automation factories and rail transit tunnels, but the bus ducts that replace cables in the market have single functions and can only They are respectively used for the transmission of power and lighting power, resulting in the high cost of power transmission and distribution systems and inconvenient installation and maintenance in industrial automation factories and rail transit tunnels where power and lighting power are required.
