CN2805169Y - Novel and high performance bus casing - Google Patents

Abstract

The utility model provides a bus duct with the advantages of high efficiency, energy saving and high safety. The utility model is composed of a bus duct casing body, insulating materials and conductors, wherein each single phase wire conductor changes one original and single chip conductor into a set of multichip conductors, and each set of the multichip conductors are formed by arranging two or more chips of conductors; the surface area of each single phase wire conductor is enlarged, therefore the power conducting capability is enhanced and the contact resistance and the temperature rise are obviously lowered. The utility model has the characteristics of low cost, electricity saving, high safety, high efficiency and favorable performance. Compared with products with the same quality and the same specification, the utility model can reduce cost by 30 per cent or so. The utility model can replace the old generation product as an inserting product for connecting a power supply, and can be used in the places of buildings, factories, markets, public facilities, etc.

Description

New and effective bus duct

Technical field

The utility model relates to a kind of bus duct that is used for conductivity, relates in particular to the conduction of a kind of high-performance, energy-conservation novel bus groove.

Background technology

Existing bus duct properties of product are low, stock utilization is low, can not adapt to developing rapidly of society.Several years ago, Tianjin Jin Lifeng fire-fighting electric equipment Co., Ltd once developed the bus duct that a kind of safety is light, the interchangeability versatility is good according to the demand in market, be characterized in shell make-up machine one-shot forming, busbar is placed on the insulating support of a series of close proximity, thereby makes bus-bar system have very high short-circuit strength.This product has improved the degree of protection of original air insulation bus duct, has reduced resistance value.But in today of economic market develop rapidly, this product also exists is worth more improved problems, still needs to improve as the utilance of electrical efficiency and material etc.

Summary of the invention

In order to improve electrical efficiency better, cut down the consumption of energy, the utility model proposes a kind of energy-efficient, safe and reliable bus duct.

The utility model is made up of bus groove case, insulating material and conductor.Wherein, key technology point of the present utility model is that each phase line conductor is originally single a slice conductor, make into now for each phase line conductor all be one group of two or two multi-disc conductor that above conductor arrangement constitutes together that leave the gap each other.

The utility model has overcome shortcomings such as original bus duct cost is higher, usefulness is lower, has that cost is low, economize on electricity, safety, efficient height, characteristics that performance is good.Be that the plain conductor surface area increases greatly than phase line conductor when the phase line conductor is many conductors, and, exist the gap to form cross-ventilation between the multi-disc conductor and can reduce conductor temperature, conductive capability is strengthened.The utility model has obviously reduced contact resistance and temperature rise, has improved the stability and the reliability of system, simple installation, and can not have replacing or extension under the situation about damaging.Through test, the utility model is than reducing cost about 30% with class same specification product.

Description of drawings

Fig. 1 is a profile front view of the present utility model.

Fig. 2 is a side-looking generalized section of the present utility model.

Among the figure, 1-bus groove case, 2-insulating material, 3-conductor.

Embodiment

The utility model is made up of bus groove case 1, insulating material 2 and conductor 3.Wherein, each phase line conductor 3 becomes one group of multi-disc conductor to original single a slice conductor.Each group multi-disc conductor is arranged by the conductor horizontal parallel more than two or two or parallel longitudinal structure arranged form is formed.Each sheet conductor leaves the gap each other.Shown in Figure 2 is that each phase line conductor is 4 a situation.Conductor is that copper or aluminum are made.Isolating by insulating material 2 insulation between each phase conductor 3 and between conductor 3 and the housing 1.Like this, the coefficient of safety of bus duct has obtained ensureing well.The phase conductor of multi-sheet structure can adopt multiple mode commonly used to be fastenedly connected and form integral body.

The grafting product that the utility model connects as power supply, renewable older generation's product is widely used in places such as building, factory, market, communal facility.

Claims (3)

1, a kind of new and effective bus duct is made up of bus groove case, insulating material and conductor, it is characterized in that: each phase line conductor all is one group of two or two multi-disc conductors that above conductor arrangement constitutes together leaving the gap each other.

2, bus duct according to claim 1 is characterized in that: arrange or parallel longitudinal structure arranged form for horizontal parallel between the multi-disc conductor of each phase line conductor.
