Low capacity recess insulated bus duct

Abstract

The invention relates to a low-capacity bus duct for motive power and illumination. The bus duct consists of an insulation separation groove, electric conduction bars, an insulation pressing block and a metal housing, wherein the insulation separation groove consists of a base plate, a side plate and a baffle plate; the baffle plate separates the insulation separation groove into two or more thantwo separation grooves; the baffle plate of the insulation separation groove separates an conductor safely; the electric conduction bars are positioned at the bottom of the inner side of the insulation separation groove, and are transversely arrayed in a plane manner; the insulation pressing block tightly presses the electric conduction bars at the bottom of the insulation groove; and an insulation body and the electric conduction bars are packaged inside the metal housing. The bus duct provided by the invention has the beneficial effects that low material cost and manual manufacturing cost, higher water-proof and dust-proof protection levels, low impedance and magnetism, and high cost performance.

Description

technical field [0001] The invention relates to 80A-500A power and lighting low-voltage power supply and distribution lines, in particular to a small-capacity bus duct for power and lighting. Background technique [0002] The existing densely insulated bus ducts and air insulated bus ducts are only suitable for the use of large-capacity power bus trunks above 630A due to the limitation of their design structures. Intensive busway (see image 3 ) and air type busway (see Figure 4 ) consists of a conductive row, an insulating film, an insulating bracket, a casing, and connecting bolts. The conductive row is placed vertically and arranged in parallel. The dense type adopts the insulation method of covering and winding the insulating film on the conductive row, so that the row and the row plane are in close contact; the air type adopts the insulating fixing bracket, and the air insulation method is used to separate the conductive row from the conductive row. The small-capacit...

AI Technical Summary

Problems solved by technology

[0003]1. Due to the similar conductive row planes, the electromagnetic induction area is large, and the electromagnetic effect of the inductance formed causes large reactance, impedance, and high reactive power loss;

[0004]2. Since the design of the lead-out of the branch line limits the thickness of the conductive row, the surface area is fixed while the cross-sectional area is determined, and the surface area of ​​the conductive row cannot be increased arbitrarily. The use of the current skin effect;

[0005]3. Intensive and air-type bus ducts are mainly suitable for large-capacity lines. When the same structure is used for small-capacity lines, the overall volume is large and the structure is complicated. Assembly Inconvenient, the material cost per ampere per meter of the product is high, and the labor cost per ampere per meter is high;

[0006]4. The cost performance is lower than that of power cables, and there is no market competitive advantage
