For solving described problem, technical scheme of the present invention: a kind of GIS dry core cable terminal, comprise body, in body, be provided with cable, the end of body is provided with the outlet gold utensil that is connected with cable core, and main insulation and outer shielding layer incision position in cable in the body are provided with stress cone and awl holder, it is characterized in that, be provided with the transducer that is used for perception stress cone temperature in the position of stress cone in the body, this transducer is connected with the lead that leads to the body outside.Described cable is owing to the qualification of material physicochemical characteristics, and its long-term work operating temperature has the requirements that are no more than 90 degree, otherwise can have influence on the effectiveness of cable, and then has influence on the job stability of cable termination.And at the terminal body in the position of stress cone because complicated electric field action, this place very easily produces higher working temperature.Described transducer promptly is used for the variations in temperature at this place of perception, can preset a critical temperature that equals 90 degree for transducer, when the temperature at stress cone place surpasses default temperature, transducer promptly produces signal, this signal is transmitted to the GIS combined electrical apparatus convergence control cabinet with band PLC Based Intelligent Control that the people keeps an eye on by lead, also can be transmitted to the GIS combined electrical apparatus Central Control Room of non intelligent control separately, realization provides foundation to the remote monitoring and the control of GIS cable termination running status for further taking the human intervention measure.
As preferably, described transducer is a Fibre Optical Sensor, and described lead is an optical fiber.Like this, transducer is little in the electric field influence that the conduction that produces signal and signal is produced by cable termination.
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.
As preferably, described stress cone is two kinds of compound making of liquid high-temperature silicon disulfide rubber by conduction and insulation.Adopt this composite material to make stress cone, make stress cone have the ability of the Electric Field Distribution of excellent control cable terminal external shield incision position.
Compared with prior art, the beneficial effect that has of the present invention:
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.
