As preferably, the position in stress cone on the described body is provided with epoxy resin bushing.Epoxy resin bushing is to be positioned on the outer peripheral face of body, and it can provide good insulation performance for body effectively.
As preferably, the position near described epoxy resin bushing on the described body is provided with the spring compression transition apparatus, and this transition apparatus and described outlet gold utensil branch are listed in the both sides of epoxy resin bushing.The spring compression transition apparatus can be for certain pretightning force is provided between the corresponding component that assembles in the body, for the connective stability between the associated components is given security.
As preferably, described transducer is between awl holder and stress cone.Under the co-extruded of awl holder and stress cone, described transducer can contact with stress cone well, and this provides assurance for transducer temperature conditions real-time, accurately perception stress cone.
For ease of of the management of this GIS dry core cable terminal, be detachable the connection between described outlet gold utensil and the body in production, storage, the process of circulation.Electric cable accessories manufacturer only needs to produce a kind of body in process of production, and for the outlet gold utensil that different size requires, and only need directly be assembled to the outlet gold utensil on the body to get final product.
As preferably, described outlet gold utensil is equipped with detachable radome outward.Detachable radome had both adapted to the structural requirement of detachable outlet gold utensil, also can give security for the work operation stability and the fail safe of outlet gold utensil simultaneously.
As preferably, the end of described body is axially arranged with screwed hole, and the end of described outlet gold utensil is provided with the trip bolt that is connected with described screwed hole.By the cooperation of trip bolt and screwed hole, realize fixedlying connected between outlet gold utensil and the body, convenient to operation.
Compared with prior art, the beneficial effect that the utlity model has:
1, because cable termination is designed to dry construction, so stopped the hidden danger of product leakage of oil.
2, owing to be provided with transducer in the cable termination, realized remote monitoring and control, guaranteed the safety in operation and the stability of terminal GIS cable termination running status.
3, since between outlet gold utensil on the terminal and body for removably connecting, by transferring the outlet gold utensil of different length regulation, can realize and the cooperation that is connected of the old and new's two generations GIS combined electrical apparatus, made things convenient for the user, be convenient to the be correlated with management of link of product.
