Description
technical field
The utility model relates to a kind of GIS miniaturization cable terminal structure, belongs to the GIS high voltage switchgear cable terminal structure technical field of 145kV and following electric pressure.
background technology
At present, the GIS high voltage switchgear of 145kV and following electric pressure adopts circuit breaker place to be connected with special-shaped conductor by supporting insulator with cable termination; End shield and contact assembling are bolted on special-shaped conductor; Conducting rod and cable plug head link together in final insertion contact.Its structural stability is poor, and electric connection point is many, and loop resistance is large, and assembling difficult point is many, and the electric connection point heating that long-time logical super-high-current causes simultaneously easily causes that loop resistance increases, and temperature rise is difficult to control.
summary of the invention
The utility model is in order to make up the defect of prior art, provides that a kind of structural stability is good, dependable performance and assemble simple GIS miniaturization cable terminal structure.
The utility model is achieved by the following technical solution:
A kind of GIS miniaturization cable terminal structure, comprise supporting insulator and housing, it is characterized in that: described enclosure interior is provided with contact base, contact base lower end is fixedly connected with new-type conducting rod, new-type conducting rod lower end is fixed with cable plug head, and housing outer end one side is provided with adsorbent assembling.
Wherein:
Described new-type conducting rod is S shape the groove with mounting spring fingertip, and housing outer end opposite side is provided with electrification display.
The utility model can, by electrification display holder housing, really meet the requirement to a main electrical scheme of GIS of national grid and south electric network, not only simplifies the structure, and provides cost savings, and is more conducive to the useful life of high voltage switchgear through-current capability and cable plug.
The beneficial effects of the utility model are: assemble simple and easy flexibly, install fastening, major loop resistance value is less, fitting operation is convenient, has shortened in the time of on-the-spot installing cables connect-disconnect plug that is not suitable for GIS assembling; Cost is low, and long service life is easy to utilize.
