Description
Technical field
This utility model relates to a kind of rhombus case enclosed busbar altogether, relates 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, rise
The effect of conveying electric energy, belong to equipment for power transmission and distribution field.
Background technology
It is total to company conventional in power control component in case enclosed busbar high and low pressure switchgear assembly and control equipment
Connect equipment, between connection transformer and switch cubicle, switch cubicle, electromotor and transformer switch cabinet equipment it
Between connection, play a part carry electric energy.The many employings of structure of prior art median generatrix are arranged in juxtaposition, bus
The layout shape of structures shape busbar cross-section, in the case of given temperature rise and busbar cross-section area, bus holds
The size of the rated value of the alternating current carried depends on the shape in its cross section, therefore uses cloth arranged side by side in prior art
Put and there is the defect that carrying alternating current rated value is low, and use the cost height of bus.
Utility model content
To be solved in the utility model is that existing busbar cross-section shape is fixed, and many employings are arranged in juxtaposition existence and hold
Carry the problem that alternating current rated value is low.
In order to solve above-mentioned technical problem, this utility model provides one carrying alternating current ability height, can save
The rhombus of bus cost case enclosed busbar altogether, including housing, is provided with the three-phase of three row's busbar assembly compositions in housing
Conductor, often row's busbar assembly includes the multiple insulators being arranged in order, it is characterised in that each described insulator
Being provided with one group of cross section is the conductor of rhombus, and it is made up of four root length strip conductors, and is fixed by bus clip
Connect；Often the bus clip on row busbar assembly connects by an attachment means is fixing；Every conductor and housing it
Between be provided with gap.
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 is from top to bottom through mother
Match with the screw thread in insulator after wire clamp；Insulator is connected by bolt two and the support in housing are fixing.
This utility model can in the case of identical temperature rise and cross-sectional area of conductor are long-pending, 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；
The front view of a kind of rhombus case enclosed busbar altogether that Fig. 2 provides for this utility model；
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 this utility model 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, approximation is relatively
Exchange rated value is as shown in the figure.As seen from Figure 1, cross-sectional area of conductor presses (scheme 7) when rhombus is arranged, its carrying
Alternating current rated value be arranged in juxtaposition (scheme 1) 1.7 times.In like manner, identical alternating current is being reached
During stream 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, be provided with in housing 1
The three-phase conductor (as shown in Figure 3) of three row's busbar assemblies compositions, often row's busbar assembly includes being arranged in order many
Individual insulator 9 (as shown in Figure 2), 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 leads to
Crossing the fixing connection (as shown in Figure 4) of bus clip 6, bus clip 6 is provided with the rhombus groove matched with conductor,
Four conductors load in rhombus groove fixing.Often the bus clip 6 on row busbar assembly is solid by an attachment means 2
Fixed connection.Bus clip 6 is connected by bolt 1 is fixing with insulator 9, and bolt 1 is from top to bottom through mother
Match with the screw thread in insulator 9 after wire clamp 6；Insulator 9 is by bolt 2 10 and propping up in housing 1
Frame is fixing to be connected, and three-phase conductor is provided with a support 1-1 below corresponding three insulators 9.
During installation, conductor 1, conductor 24, conductor 37, conductor 48 are abutted against the four of bus clip 6
In the rhombus groove in week, cross section assumes diamond in shape arrangement.Bolt 1 screws in the spiral shell above insulator 9 through bus clip 6
Pit, after bolt 1 fastening, by bus clip 6, conductor 1, conductor 24, conductor 37, conductor 48
It is fixed on together on insulator 9.It is connected with housing 1 by bolt 2 10 bottom insulator 9, conductor 1,
Must keep enough electric clearances between conductor 24, conductor 37, conductor 48 and housing 1, case is closed altogether
The the most biphase of bus is arranged in housing 1 in the same way, and one end of attachment means 2 is revealed from housing 1
Go out, for connecting with adjacent rhombus case enclosed busbar altogether.
