Abstract

The utility model discloses a stretchable air bus bridge, which consists of a bridge pier, a bridge body and a bus. The connecting part of two sections of bridge body is formed by adopting a piston type inserted connection; and a copper bar lap joint part of the bus is formed by connecting flexible buses. The utility model directly improves and changes on the basis of the prior style, the primarily-fixed abut joint of the connecting part of bridge bodies is changed into the stretchable piston type inserted connection and fixed bus connection at the lap joint part of copper bars is changed into the flexible bus connection, therefore, the utility model can ensure that the length of the lap joint of the bridge body can be only adjusted in a certain error range without remanufacturing the bus bridge and the bus, and thereby the accuracy of the bus connection can be improved, the loss can be reduced and social benefit can be improved.

Description

A kind of extension type air bus bridge

Technical field

The utility model relates to the high and low voltage switch cabinet, particularly be the connection that is used for high and low voltage switch cabinet main bus bar.

Background technology

As the low-tension switch cabinet of conveying and electrical power distribution after the step-down of electric power network high-tension switch cabinet, it has been widely used in different places.For the frame mode of outlet behind the horizontal bus overhead type of domestic custom employing, its vertical bus is positioned at the cabinet rear side, takies the cabinet degree of depth, and hinders outlet.In traditional low-voltage cabinet, fixedly the separation function unit connects with all requiring on vertical bus punching being connected of vertical bus, this has brought inconvenience to installation, so how can accomplish not only to save the space but also cabinet body structure easy for installation has problem to be solved with regard to having become one.

The air type bus bridge that connects main bus bar in the high and low voltage switch cabinet that is useful on that has now on market is welded type or assembly type, as Fig. 3 in the Figure of description and Fig. 4: it is by

bridge pier

31,32 and the body of a

bridge

33,34 and main bus bar 35 form, its body of a

bridge

33,34 length generally provides drawing to decide by on-the-spot actual measurement or according to the user, so just often produce the situation that measure error and actual installation position and drawing are not inconsistent, the present bus bridge of producing, its body of a

bridge

33,34 length is fixed, uncontrollable, and the

bridge pier

31,32 and the body of a bridge 33 of both sides, be fixedly connected between 34, in a single day distance between them determines it is unmodifiable, the connection bus that is provided with between the two sections body of a

bridge

33,34 inside, distance between them is fixing by the distance between the body of a bridge, in case change between the body of a

bridge

33,34, bus will be readjusted length, and the bus that need more renew, caused the waste of resource.36 all is fixed butt joint in the connection place, so in case construction error takes place or measure mistake, just must make the body of a bridge and bus again, thereby cause the loss of a large amount of human and material resources and financial resources.

The utility model content

It is unadjustable that the utility model has overcome above-mentioned bus bridge height degree, on-the-spot combination scale error and shortcoming such as cause that engineering is done over again, and provide a kind of can be at telescopic bus bridge in the effective fitting limit.

To achieve these goals, the utility model is to realize by the following technical solutions:

A kind of extension type air bus bridge, this bus bridge is made up of bridge pier, the body of a bridge and bus, and the connection place of described two sections body of a bridgies adopts piston type to insert connection, and the copper bar lap-joint of described bus adopts flexible bus to connect.

The utility model is directly to improve on the basis of former pattern and change, change the piston type insertion connection that can stretch with the connection place of the body of a bridge by original fixed butt joint at the body of a bridge, and copper bar lap-joint is connected to change into by fixing bus and adopts flexible bus to connect, can guarantee like this in certain error range, the length that only needs to regulate body of a bridge lap-joint gets final product, and need not to make again bus bridge and bus, improved the accuracy that bus connects, reduce loss, improved social benefit.

Description of drawings

Describe the utility model in detail below in conjunction with the drawings and specific embodiments;

Fig. 1 is the structural representation of the utility model extension type air bus bridge.

Fig. 2 is the vertical view of the utility model extension type air bus bridge.

Fig. 3 is the structural representation of fixed air bus bridge in the prior art.

Fig. 4 is the vertical view of fixed air bus bridge in the prior art.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.

With reference to figure 1 and Fig. 2:

A kind of extension type air bus bridge, this bus bridge is made up of

bridge pier

11,12, the body of a

bridge

13,14 and bus 15, bridge pier generally all is provided with two, about each one, be placed with the bus 15 that connects in the high and low voltage switch cabinet in the inside of

bridge pier

11,12, the air type bus bridge is welded type or assembly type generally speaking, it is by

bridge pier

11,12 and the body of a

bridge

13,14 and main busbar composition.

In order to regulate two body of a bridgies 13, distance between 14, at two sections body of a bridgies 13, the piston type that present extension type is arranged to by original fixed butt joint in 14 connection place inserts connection, insert the distance that connection can be adjusted two sections body of a

bridgies

13,14 by piston type like this, guarantee under the situation of certain error range, the length that only needs to regulate body of a bridge lap-joint gets final product, and need not to make again bus bridge and bus; Copper bar lap-joint is connected by fixing bus and changes flexible bus 16 into and connect, like this can be along with the activity between the body of a

bridge

13,14 is regulated, and bus 15 also can change along with the change of the distance between the distance of the body of a

bridge

13,14.

When mounted, at first provide drawing to decide the size dimension of extension type air bus bridge according to on-the-spot actual measurement or according to the user, so just can prevent the phenomenon that the measure error that produces and actual installation position and drawing are not inconsistent, manufacturing and designing

bridge pier

11,12 and the body of a bridge 13, in the time of 14 bus 15 is installed in bridge pier 11 respectively, 12 and the body of a

bridge

13,14 bosom position, connect with flexible bus 16 in copper bar lap-joint, can change the length of bus 15 like this along with the variation of the body of a

bridge

13,14 positions, by the body of a bridge 13, piston type between 14 inserts and connects, can in different high and low voltage switch cabinets, change its size flexibly, adopt flexible bus 16 to flexibly connect, increase its scope of application.
