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 small busbar combination fully insulated closed busbar belongs to the technical field of low-voltage electrical transmission and distribution busbars and branch busbars, including busbars, busbar interfaces, cable crimping outlet devices, busbar vertical tees and busbar vertical elbows. In the present invention, the busbar adopts the combined structure design of small copper bars. The heat dissipation area of ​​the single-phase small copper bars is several times that of the existing busbars, and the amount of copper can be moderately reduced, which can significantly reduce the cost of product materials. The bus bar is four-phase and each phase has high mechanical strength of independent insulation. The busbar interface adopts the non-insulated bolt connection scheme, and the material cost is significantly reduced. The standardization rate is extremely high, the busbar production process is simple, the production cost is low, and the production efficiency is high, which greatly improves the utilization rate of inventory funds. The busbar in the present invention has the core concept of independent innovation, cost reduction and efficiency increase, and safety first in the design of key schemes such as busbar structure, outlet mode, interface, vertical tee, and vertical elbow, and can truly realize product maintenance-free and life-long A corporate commitment to quality.

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...
