Description

A kind of bus connecting device

Technical field

This utility model relates to a kind of bus connecting device, and this device, in high-low pressure switchgear assembly, plays Connect conductor effect, belong to equipment for power transmission and distribution field.

Background technology

Bus is the common electric accessory in high and low pressure switchgear assembly, plays a part to carry electric current.? In the case of given temperature rise and sectional area, the size of bus exchange rated value depends on the shape in the cross section of its conductor Shape, the rectangular conductor commonly used in switchgear assembly, the size of its exchange rated value depends on its conductor Arrangement mode.When four rectangular conductor cross sections are diamond array, its exchange rated value is more than other arrangement modes, Can effectively save conductor cost, but because its connect difficulty and can not popularization and application.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of connect reliable, easy for installation, be prone to inspection The bus connecting device repair, easily promoted, solves in switchgear assembly, and using four cross sections is diamond array Rectangular conductor time, connect difficulty and can not the problem of popularization and application.

In order to solve above-mentioned technical problem, the technical solution of the utility model there is provided a kind of bus and connects dress Put, it is characterised in that include cushion block, cushion block be formed around four pieces of connecting plates, the two ends of four pieces of connecting plates are divided Be not connected with two groups of bus-bars conductor groups outside it, one end of every piece of connecting plate all with its outside a bus lead Body connects, and often group bus-bars conductor group is made up of four bus-bars conductors, the cross sectional arrangements diamondwise of four bus-bars conductors Shape.

Preferably, described cushion block be cross section be foursquare cuboid, four pieces of connecting plates are respectively placed in cushion block Surrounding.

Preferably, four rectangle faces of described cushion block are provided with two groups of holes being mutually perpendicular to, front and back staggering.

Preferably, described two groups of bus-bars conductor groups are connected with cushion block by two groups of bolts, and two groups of bolts are mutually to hang down The mode staggered before and after straight, sequentially passes through bus-bars conductor, connecting plate and cushion block.

This utility model can connect the conductor of diamond array, have connection reliable, easy for installation, be prone to maintenance Advantage, and make conductor diamond array technology be promoted, save bus cost.

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.

Enumerating 7 kinds of busbar arrangement schemes, its sectional area is 10000mm2, and approximation exchanges rated value relatively, As shown in Figure 1.As can be seen here, busbar cross-section presses (scheme 7) when rhombus is arranged, the alternating current of its carrying Stream rated value is be arranged in juxtaposition (i.e. scheme 1) 1.7 times.In like manner, to reach identical alternating current specified During value, scheme 7 can save the bus cost of 41% than scheme 1.

This utility model is a kind of bus connecting device, is diamond array for connecting four rectangular conductor cross sections, As shown in Fig. 2-1, Fig. 2-2, Fig. 2-3, it includes cushion block 13, connecting plate, bolt three part, cushion block 13 Four faces on be fitted with connecting plate, put in the middle of the bus-bars conductor of four diamond arraies, and by bolt even Fishplate bar in succession.The i.e. two ends of four pieces of connecting plates are connected with two groups of bus-bars conductor groups outside it respectively, every piece of connection One end of plate is all connected with a bus-bars conductor outside it, and often group bus-bars conductor group is by four bus-bars conductor groups Becoming, the cross sectional arrangements diamondwise shape of four bus-bars conductors, two groups of bolts 12 are to be mutually perpendicular to the side front and back staggered Formula, through bus-bars conductor, connecting plate and cushion block 13, is pressed on bus-bars conductor on connecting plate.

Cushion block 13 is foursquare cuboid for cross section, on four rectangle faces of cushion block 13, has two groups of phases The hole vertically, front and back staggered mutually.Connecting plate is arranged on four rectangular of cushion block 13, connecting plate Hole is concentric with the hole of cushion block 13, and four strip conductors of diamond array are clipped on the connecting plate of cushion block 13 surrounding respectively, Through bus-bars conductor, connecting plate, cushion block 13 and screw with bolt 12, bus-bars conductor be pressed on connecting plate, Will be connected with bus connecting device of the present utility model by bus-bars conductor.Use same at the other end of the present utility model The method of sample is connected with another group bus-bars conductor, thus is connected by two groups of conductors.

One group of bus-bars conductor group is attached with another group bus-bars conductor group, and during actual application, these are led Body section assumes diamond in shape arrangement, and its process is as follows:

First, four faces of cushion block 13 are respectively mounted first connecting plate the 9, second connecting plate the 10, the 3rd Connecting plate the 11, the 4th connecting plate 14, be then placed in the middle of one group of bus-bars conductor group (the i.e. first bus-bars conductor 1, In the rhombus that second bus-bars conductor 2, triple bus-bar conductor the 3, the 4th bus-bars conductor 4 surround).By one group of bolt 12 lead through triple bus-bar conductor the 3, second connecting plate 10, cushion block the 13, the 4th connecting plate the 14, first bus Fasten after body 1；Again by another group bolt 12 through the second bus-bars conductor the 2, the 3rd connecting plate 11, cushion block 13, Fasten after first connecting plate the 9, the 4th bus-bars conductor 4.In kind, by another group bus-bars conductor group (i.e. 5th bus-bars conductor the 5, the 6th bus-bars conductor the 6, the 7th bus-bars conductor the 7, the 8th bus-bars conductor 8) it is arranged on pad On outside the other end of block 13 and connecting plate, thus complete the connection of two groups of conductors.

Wherein, often group bolt has at least two bolt 12 and nut.
