Abstract
The invention discloses a rhombic nonsegregated-phase busbar comprising a shell. A three-phase conductor consisting of three rows of busbar components is arranged in the shell, and every row of busbar components includes a plurality of insulators in sequential arrangement. The rhombic nonsegregated-phase busbar is characterized in that a group of conductors with rhombic cross sections is arranged on every insulator and includes four conductors fixedly connected through busbar clamps, the busbar clamps on every row of busbar components are fixedly connected through a connecting device, and a gap is reserved between every conductor and the shell. The rhombic nonsegregated-phase busbar has the advantages of high loaded rated alternating current, high mechanical strength and lower conductor cost under the conditions of same temperature rise and conductor sectional area.
Description
Technical field
The present invention relates to a kind of rhombus case enclosed busbar altogether, relate generally in high-low pressure switchgear assembly, for between connection transformer and switch cubicle, switch cubicle, the connection of electromotor and transformer switch cabinet equipment, play a part conveying electric energy, belong to equipment for power transmission and distribution field.
Background technology
It is total to connection equipment conventional in power control component in case enclosed busbar high and low pressure switchgear assembly and control equipment, for the connection between connection transformer and switch cubicle, switch cubicle, between electromotor and transformer switch cabinet equipment, play a part conveying electric energy.The many employings of structure of prior art median generatrix are arranged in juxtaposition, bus structure determines the layout shape of busbar cross-section, when given temperature rise and busbar cross-section area, the size of the rated value of the alternating current of bus carrying depends on the shape in its cross section, therefore prior art adopts to be arranged in juxtaposition and there is the defect that carrying alternating current rated value is low, and use the cost height of bus.
Summary of the invention
To be solved by this invention is that existing busbar cross-section shape is fixed, and adopt is arranged in juxtaposition the problem that existence carrying alternating current rated value is low more.
In order to solve above-mentioned technical problem, the present invention provides a kind of and carries the rhombus case enclosed busbar altogether that alternating current ability is high, can save bus cost, including housing, the three-phase conductor of three row's busbar assembly compositions it is provided with in housing, often arrange multiple insulators that busbar assembly includes being arranged in order, it is characterised in that it is the conductor of rhombus that each described insulator is provided with one group of cross section, it is made up of four root length strip conductors, and connects by bus clip is fixing；Bus clip on each row busbar assembly connects by a connecting device is fixing；It is provided with gap between every conductor and housing.
Preferably, described bus clip is provided with the rhombus groove matched with conductor.
Preferably, described bus clip is connected by bolt one and insulator are fixing, and bolt one matches with the screw thread in insulator from top to bottom after bus clip；Insulator is connected by bolt two and the support in housing are fixing.
The present invention can when identical temperature rise and cross-sectional area of conductor be long-pending, and the rated alternating current of carrying is big, mechanical strength is high, save conductor cost.
Accompanying drawing explanation
Fig. 1 is the comparison diagram that bus exchanges rated current when various arrangement mode；
Fig. 2 is the front view of a kind of rhombus provided by the invention case enclosed busbar altogether；
Fig. 3 is the top view of Fig. 2；
Fig. 4 is the side view of Fig. 2.
Detailed description of the invention
For making the present invention become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
In FIG, listing seven kinds of conductor arrangements, its sectional area is 10000mm2, the approximate rated value of exchange relatively is as shown in the figure.As seen from Figure 1, cross-sectional area of conductor presses (scheme 7) when rhombus is arranged, the alternating current rated value of its carrying is 1.7 times that are arranged in juxtaposition (scheme 1).In like manner, when reaching identical alternating current rated value, scheme 7 can save the bus cost of 41% than scheme 1.
Therefore, present embodiments provide a kind of rhombus case enclosed busbar altogether, including housing 1, the three-phase conductor (as shown in Figure 3) of three row's busbar assembly compositions it is provided with in housing 1, often arrange multiple insulators 9 (as shown in Figure 2) that busbar assembly includes being arranged in order, it is the conductor of rhombus that each described insulator 9 is provided with one group of cross section, it is by four root length strip conductors, i.e. conductor 1, conductor 24, conductor 37 and conductor 48 composition, and connect (as shown in Figure 4) by bus clip 6 is fixing, bus clip 6 is provided with the rhombus groove matched with conductor, four conductors load in rhombus groove fixing.Bus clip 6 on each row busbar assembly connects by a connecting device 2 is fixing.Bus clip 6 is connected by bolt 1 is fixing with insulator 9, and bolt 1 matches with the screw thread in insulator 9 from top to bottom after bus clip 6；Insulator 9 is connected by bolt 2 10 and the support in housing 1 are fixing, and on three-phase conductor, corresponding three insulators 9 are connected with a support 1-1.
During installation, conductor 1, conductor 24, conductor 37, conductor 48 being abutted against in the rhombus groove of surrounding of bus clip 6, cross section assumes diamond in shape arrangement.Bolt 1 screws in the screwed hole above insulator 9 through bus clip 6, after bolt 1 fastening, bus clip 6, conductor 1, conductor 24, conductor 37, conductor 48 is fixed on together on insulator 9.It is connected with housing 1 by bolt 2 10 bottom insulator 9, enough electric clearances must be kept between conductor 1, conductor 24, conductor 37, conductor 48 and housing 1, the additionally biphase of case enclosed busbar is arranged in housing 1 in the same way altogether, one end of connecting device 2 is exposed from housing 1, for connecting with adjacent rhombus case enclosed busbar altogether.
