The beneficial effects are that can compress tightly the group of conductors completely, eliminate the group of conductors and produce mechanical oscillation because of the electric power, eliminate the odd harmonic of the defeated in -process of telex, improve quality of supply, can effectively reduce temperature rise, increase of service life moreover.

Description

A kind of compact type bus groove case

Technical field

This utility model belongs to low pressure dispensing electric installation field, especially relates to a kind of compact type bus groove case.

Background technology

Bus groove case joins power transmission system for low pressure, middle part has the accommodation cavity holding conductor group, low tension is transmitted by conductor group, traditional bus groove case can not compacted conductor group completely, again owing to conductor group itself can because electric power produces mechanical vibration, so in use there is the problem that conductor group vibration noise is big in traditional bus groove case, conductor group is vibrated in magnetic field, also can produce odd harmonic, reduces power supply quality, temperature also can raise substantially simultaneously, reduction of service life.

Utility model content

In view of this, this utility model is directed to a kind of compact type bus groove case, it is possible to compacted conductor group completely, eliminate conductor group and produce mechanical vibration because of electric power, eliminate the odd harmonic in electricity transmitting procedure, improve power supply quality, and can effectively reduce temperature rise, increase the service life.

For reaching above-mentioned purpose, the technical solution of the utility model is achieved in that

A kind of compact type bus groove case, including the cover plate and the side plate that are spliced into " II " shape, described cover plate is positioned at upper and lower both sides, described side plate is positioned at the left and right sides, the described cover plate of both sides and the middle part of described side plate are provided with the conductor group for laying conductor group and hold chamber, the two ends up and down in described conductor group accommodation chamber are respectively connected with a stay tube of hollow cuboid, described stay tube has corresponding the first through bolt hole in left and right with the contact position of described side plate, and the contact position of described cover plate and described side plate has the second corresponding through up and down bolt hole.

Further, described stay tube is that " [" shape semicanal is butted into square-tube-shaped for hollow square tube or two.

Further, described conductor group holds the left and right width left and right thickness less than conductor group in chamber.

Relative to prior art, compact type bus groove case described in the utility model has the advantage that

nullThis utility model is spliced into the structure of bus groove case by cover plate and side plate，The conductor group at middle part holds chamber can hold conductor group，And conductor group is held the width on the left and right directions of chamber and is slightly less than the thickness of conductor group，When conductor group is placed into conductor group accommodation intracavity，The effect of interference fit can be produced，Side plate is made to produce minute elastic deformation，The stay tube being arranged on the upper and lower two ends of conductor group realizes being connected with side plate fixing by stay bolt and nut，Side plate can compress the conductor group at middle part，And a stay tube is applied thrust by the side plate producing miniature deformation simultaneously，Contribute to a further compacted conductor group of stay tube，Eliminate conductor group and produce mechanical vibration because of electric power，Avoid vibrating in magnetic field，Generation odd harmonic can be prevented effectively from，Promote power supply quality，Simultaneously，Propping up stay tube is hollow cuboid，Hollow-core construction contributes to heat radiation，Temperature rise can be reduced，Increase the service life.Prop up the space that the space between stay tube and upper and lower cover plates is reserved cabling.
