Description
Technical field
The utility model is related to switch cubicle electrical current carriers field, more particularly to a kind of New bar class current-carrying attachment means.
Background technology
Mainly there is two ways through-flow in existing box type aeration switch cubicle, one kind is to use flat copper line as electrical current carriers,
It is bolted connection realization；Another realized by the conventional quiet overlap joint of copper rod bolt, the dynamic overlap joint of other end fingertip.
But, the equal Shortcomings of both the above mode, the field strength distribution of first way copper bar is uneven, insulating properties compared with
Difference, and faying surface contact resistance is larger, temperature rise is higher；The second way copper rod and bolt lap-joint there is also Electric Field Distribution not
Uniform situation, and it is larger to requirements of installation space, in the case where meeting class of insulation requirement, cabinet size can not meet small-sized
Change and integrated user requires.
The content of the invention
The utility model is in view of the shortcomings of the prior art there is provided a kind of New bar class current-carrying attachment means, and CURRENT DISTRIBUTION is more
Plus it is uniform, while reducing space-consuming.
The utility model is achieved by the following technical solution there is provided a kind of New bar class current-carrying attachment means, is used for
Bus-bar insulator and busbar copper pipe are connected, the attachment means include offering the connection body of through hole, one end of the through hole
Affixed by screw thread and the bus-bar insulator, the other end is offered at least one fingertip mounting groove, the fingertip mounting groove
Fingertip is installed, the busbar copper pipe sequentially passes through the endoporus of each fingertip, and is not contacted with bus-bar insulator, this programme, which is utilized, to be touched
Refer to and screw thread realize the current-carrying of busbar copper pipe and bus-bar insulator, Electric Field Distribution with good insulating.
It is provided with internal thread, bus-bar insulator and sets with the junction of bus-bar insulator as optimization, on the through hole
There is the external screw thread being adapted to the internal thread, it is easy to connect, reduce installation dimension.
As optimization, the fingertip mounting groove be two, along the through hole axis direction arrange, it is ensured that overlap joint it is reliable
Property, reduce heating.
As optimization, the connection body is cylinder, and the axis of the through hole is overlapped with being connected the axis of body, convenient
Production and processing and installation.
As optimization, the connection body is towards the screw being additionally provided with the one end side of busbar copper pipe circumferentially
Hole, lid screw hole is easy to connect the fixation of body as reserving installation hole.
The beneficial effects of the utility model are：Busbar copper pipe and bus insulation are realized using the fingertip and screw thread of attachment means
The current-carrying of son, in the case of current-carrying is met, Electric Field Distribution is more uniform, and insulating properties are more preferable, and this kind of connected mode is saved
Space, convenient installation, debugging are simple in construction, and low to requirement on machining accuracy, stability is high, meet miniaturization and integrated requirement.

Embodiment
For the technical characterstic for illustrating this programme can be understood, below by embodiment, this programme is illustrated.
A kind of New bar class current-carrying attachment means as shown in Figure 1, between bus-bar insulator 1 and busbar copper pipe 4, are used for
Bus-bar insulator 1 and busbar copper pipe 4 are connected, the attachment means include offering on the connection body 2 of cylinder, connection body 2
Through hole, and axis coincidence of the axis of through hole with being connected body 2.
One end of through hole is affixed by screw thread and bus-bar insulator 1, and the junction on through hole with bus-bar insulator 1 is provided with
The external screw thread being adapted to the internal thread is provided with internal thread, bus-bar insulator 1.The other end of through hole offers two along through hole
Axis arrangement fingertip mounting groove, be mounted on fingertip 3 in fingertip mounting groove, busbar copper pipe 4 sequentially passes through the interior of each fingertip 3
Hole, and do not contacted with bus-bar insulator 1.
In connection body 2 towards four screw holes 5 being additionally provided with the one end side of busbar copper pipe 4 circumferentially, use
Fixed in the installation of connection body 2.
Such a attachment means install simple with dismounting, reduce production and the cost of overhaul, and save space, pass through fingertip
The current-carrying of busbar copper pipe and bus-bar insulator is realized with screw thread, in the case of current-carrying is met, Electric Field Distribution is more uniform, insulating properties
Can be more preferably.
Certainly, described above is also not limited to the example above, and technical characteristic of the utility model without description can lead to
Cross or realized using prior art, be will not be repeated here；Above example and accompanying drawing are merely to illustrate technology of the present utility model
Scheme is not to limitation of the present utility model, with reference to preferred embodiment the utility model is described in detail, originally
Field it is to be appreciated by one skilled in the art that those skilled in the art institute in essential scope of the present utility model
The variations, modifications, additions or substitutions made are without departure from objective of the present utility model, and should also belong to right of the present utility model will
Seek protection domain.
