Abstract
The utility mode discloses a bus duct. The bus duct comprises a case, an accommodating cavity is formed in the case, a plurality of conductors are parallelly arranged in the accommodating cavity, insulating strips are respectively arranged on two sides of each conductor, planar insulating films are arranged on two opposite surfaces of each conductor, and the planar insulating films simultaneously are utilized to separate two adjacent conductors and two adjacent insulating strips. The bus duct has the advantages that the processing technology is simple, the service life is long, and the energy is saved during operating.
Description
Technical field
The utility model relates to a kind of bus duct.
Background technology
Existing bus duct comprises housing, parallelly in housing is provided with many strip conductors, in order to guarantee the insulation between each conductor, the existing practice as shown in Figure 1 and Figure 2, with conductor 20 parcels, this structure has following defective to dielectric film 10 by the mode that coats:
1, dielectric film 10 when coating conductor, needs hot briquetting, has increased processing technology, and technique is more complicated, and the reasonably more difficult control of shape and size;
2, general polyester materials or other insulating material of adopting of dielectric film 10 made, and when the heating bending, insulating material is local can Yin Gaowen and suffer in various degree destruction, according to the octave principle, certainly will affect security of operation and the useful life of product;
3, dielectric film 10 is when coating conductor 20, because of the shape and size of dielectric film 10 together with can not fully fitting between conductor, must produce a large amount of leaving a blank between conductor 20 and housing 30, and the temperature rise of leaving a blank for bus duct is very fatal, to cause temperature rise, the impedance of conductor 20 large, in running, line loss is large, and energy consumption is high.
Summary of the invention
Based on this, the utility model is to overcome the defective of prior art, and a kind of bus duct is provided, and processing technology of the present utility model is simple, and long service life is more energy-conservation during operation.
Its technical scheme is as follows:
A kind of bus duct, comprise housing, form placed cavity in housing, walk abreast in placed cavity and be provided with many strip conductors, be respectively equipped with plane insulation strip in the both sides of each conductor, two apparent surfaces at conductor are provided with dielectric film, and dielectric film separates two adjacent conductors, two adjacent insulation strip simultaneously.
The below describes further technical scheme:
Described housing comprises two cover plates, and the both sides of described dielectric film extend to the inboard of two cover plates.
The both sides of described conductor are evagination circular arc, and described insulation strip is interior concave arc and matches with described conductor shape near described conductor one side, and opposite side is provided with groove, and under nature, the width of insulation strip is greater than the distance of the described housing of conductor both sides distance.
Described groove is rectangular.
The below describes advantage or the principle of aforementioned techniques scheme:
1, realize insulation by dielectric film and insulation strip, in the course of processing, dielectric film does not need the high temperature bending, and technique is simpler, and efficiency of assembling is high, and longer service life.
2, realize insulation by dielectric film and insulation strip, each stacking part get final product, emptying more thorough in housing, product temperature rise in running is low, the impedance of conductor is little, energy consumption is low, and product safety move, just more secure with the life-span.
3, insulation strip one side is interior concave arc, can position conductor, avoids conductor to rock, and the length of opposite side slightly is longer than the distance of the described housing of conductor both sides distance, can avoid due to leaving a blank that mismachining tolerance is brought when distortion.

Embodiment
The below is elaborated to embodiment of the present utility model:
As shown in Figure 3, Figure 4, a kind of bus duct, comprise housing 30, the interior formation placed cavity of housing 30, walk abreast in placed cavity and be provided with many strip conductors 20, be respectively equipped with insulation strip 50 in the both sides of each conductor 20, be provided with plane dielectric film 40 two apparent surfaces of conductor 20, dielectric film 40 separates two adjacent conductors 20, two adjacent insulation strip 50 simultaneously.
Wherein, described housing 30 comprises two cover plates, and the both sides of described dielectric film 40 extend to the inboard of two cover plates.The both sides of described conductor 20 are evagination circular arc, described insulation strip 50 is interior concave arc 52 and matches with described conductor 20 shapes near described conductor 20 1 sides, opposite side is provided with groove 51 (wherein, described groove is rectangular), under nature, the width of insulation strip 50 is greater than the distance of the conductor 20 described housings 30 of both sides distance.
The present embodiment has following advantage:
1, realize insulation by dielectric film 40 and insulation strip 50, in the course of processing, dielectric film 40 does not need the high temperature bending, and technique is simpler, and efficiency of assembling is high, and longer service life.
2, realize insulation by dielectric film 40 and insulation strip 50, each stacking part get final product, emptying more thorough in housing 30, product temperature rise in running is low, the impedance of conductor is little, energy consumption is low, and product safety move, just more secure with the life-span.
3, insulation strip 50 1 sides are interior concave arc 52, can position conductor 20, avoid conductor 20 to rock, and the length of opposite side slightly is longer than the distance of the conductor 20 described housings 30 of both sides distance, can avoid due to leaving a blank that mismachining tolerance is brought when distortion.
The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.
