Description

A kind of syndeton of isolated bus conductive cores

Technical field

The utility model relates to a kind of high-voltage insulated bus syndeton, is more specifically oneplant the syndeton of isolated bus conductive cores, belong to power equipment technical field.

Background technology

Isolated bus is generally used for the transmission of high-tension electricity, and existing isolated bus is comprised of conductive cores and screen, screen by alternating packets overlay on conductive cores outer insulation, capacitance pole flaggy forms.Conductive cores adopts conductive metal pipe conventionally, as copper pipe etc.

Isolated bus syndeton is for connecting two sections of isolated buses, relates to the connection of conductive cores in isolated bus connects, and the connection request junction of conductive cores has good conductivity, also will guarantee the mechanical strength of junction.

State Intellectual Property Office's on October 27th, 2010 disclosed " a kind of high-voltage insulated bus connector and attaching method thereof " patent documentation (publication number: 101872907A), the high-voltage insulated bus connector of Introduction of Literatures, the connection of conductive cores adopts conduction tube connector, by extruding, conduct electricity tube connector outside, make to conduct electricity tube connector and conductive metal pipe tight fit.The method of this crimp not only makes to conduct electricity fixedly defective tightness of tube connector and conductive metal pipe, affects conductivity and the mechanical strength of junction, also makes the complicated operation connecting simultaneously.

In addition, State Intellectual Property Office's on August 21st, 2013 disclosed " a kind of syndeton of conductive cores of high-voltage insulated bus " patent documentation (publication number: 203150750U), the syndeton of the conductive cores of the high-voltage insulated bus of Introduction of Literatures, connector comprises connector and is arranged on the fixed body of connector two sides, connector is cylinder, the external diameter of connector equates with the external diameter of conductive cores, connector is between the connecting end surface of two conductive cores, the fixed body of connector two sides penetrates respectively in two conductive cores, make the fixing compact of conductive cores and connector, conductivity and the mechanical strength of junction have been guaranteed, but this syndeton, the complex structure of connector, the making trouble of connector, also make attended operation inconvenience simultaneously.

Utility model content

For above-mentioned situation, it is simple that the problem that the utility model quasi-solution is determined is to provide a kind of conductive cores syndeton, and attended operation is convenient, and junction mechanical strength is high, the high-voltage insulated bus syndeton of good conductivity.

For achieving the above object, the utility model has adopted following technical scheme: a kind of syndeton of isolated bus conductive cores, it comprises conductive cores tube connector, the external diameter of the internal diameter of described conductive cores tube connector and the conductive cores of high-voltage insulated bus coincide, on the inwall of described conductive cores tube connector, there are two sections of screw threads, in the conductive cores of described two high-voltage insulated bus links, be respectively equipped with screw thread, screw thread and the screw thread in conductive cores of described tube connector inwall are intermeshing.

Described tube connector inwall is set to the screw thread in conductive cores: the hand of spiral in described two conductive cores is consistent, the opposite direction of two sections of screw threads on the inwall of described conductive cores tube connector; Or the direction of two sections of screw threads on the inwall of described conductive cores tube connector is consistent, the hand of spiral in described two conductive cores is contrary.

Adopt such scheme, the syndeton of isolated bus conductive cores of the present utility model, conductive cores connection has adopted conductive cores tube connector, on the inwall of conductive cores tube connector, there are two sections of screw threads, in two conductive cores, be respectively equipped with screw thread, and being set to of screw thread: the hand of spiral in two conductive cores is consistent, the opposite direction of two sections of screw threads on the inwall of conductive cores tube connector; Or the direction of two sections of screw threads on the inwall of described conductive cores tube connector is consistent, the hand of spiral in two conductive cores is contrary.By rotating conductive cores tube connector, conductive cores tube connector can be screwed into or two conductive cores of can simultaneously back-outing simultaneously, has both made conductive cores syndeton simple like this, and attended operation is convenient, also guarantees junction mechanical strength and conductivity.
