Embodiment Construction

[0046] At present, there are two main products of low-voltage busbars in my country. 1: Air-type busbars. As the name implies, the insulating medium between copper bars is air, that is to say, it is insulated by air. The main structure is composed of: metal shell A, (cold-rolled thin steel plate , aluminum alloy profiles), insulating bracket D (DMC unsaturated resin glass fiber reinforced plastic), copper bar B, etc., copper bar B and metal shell A are isolated by insulating bracket D, and there are copper bars B between each phase A certain space distance, solid and called the air bus, the structure see figure 1 . 2: Intensive busbar, the insulation medium between copper bars B is organic insulating film or heat shrinkable sleeve E, the main structure is composed of: metal shell A (cold-rolled thin steel plate, aluminum alloy profile), polyethylene film or heat shrinkable sleeve Tubes, assembly rivets F, etc., each phase copper bar B is individually covered by polyethylene fil...

Abstract

The invention discloses a small busbar combined all-insulated enclosed bus, and belongs to the technical field of buses and branch buses for low-voltage electrical transmission and distribution. The small busbar combined all-insulated enclosed bus comprises a bus, bus interfaces, cable crimping outgoing line devices, bus vertical tees and bus vertical elbows, wherein the bus adopts a small copperbar combined structure design, the heat dissipation area of a single-phase small copper bar is several times that of an existing bus, the copper consumption can be properly reduced, and the product material cost can be obviously reduced. The bus has four phases and each phase has independent insulation and high mechanical strength. A bus interface adopts a non-insulating bolt connection scheme, and therefore the material cost is obviously reduced. The standardization rate is extremely high, the bus production process is simple, the production cost is low, the production efficiency is high, andthe stock fund utilization rate is greatly improved. The bus provided by the invention has the core concepts of independent innovation, cost reduction, benefit increase, safety and first in key scheme design of a bus structure, a wire outlet mode, an interface, a vertical tee joint, a vertical elbow and the like, and can truly realize enterprise commitment of maintenance-free and lifelong qualityguarantee of a product.

Description

technical field [0001] The invention belongs to the technical field of low-voltage electrical transmission and distribution busbars and branch busbars, and in particular relates to a fully insulated closed busbar combined with small busbars. Background technique [0002] The application of low-voltage power distribution busbars in my country is mainly divided into two stages. 1: From the 1960s to the 1980s, bare copper (aluminum) conductive bars were used to insulate overhead with porcelain insulators. Since organic insulating materials were not popular at that time, so The power transmission and distribution busbar products at this stage belong to the primary connection section and will not be described in detail. 2: Since the 1990s, due to the popularization and application of new materials such as organic insulating materials (DMC, PE), cold-rolled thin steel plates, and aluminum alloy profiles, products such as air-type closed busbars and dense-type closed busbars have ap...
