Description
Technical field
The present invention relates to a kind of electric cable accessories, relate in particular to a kind of GIS dry core cable terminal of not having oil.
Background technology
In recent years; Because the electric load of down town rises year by year, for improving the supply of electrical energy quality in medium and small city, the through successively down town of 110KV transformer station; But local-style dwelling houses such as the down town is commercial, financial, logistics thick and fast; The unsuitable transformer station that sets up open type can only take a kind of gas-insulated metal-enclosed formula combined electrical apparatus usually, is called for short GIS.It is that equipment except that transformer such as circuit breaker, earthed switch, isolating switch, voltage transformer, current transformer, lightning arrester etc. in the transformer station all are enclosed in the metal shell of ground connection, and utilizes SF
6Gas is as arc extinguishing and dielectric.This GIS volume is little, in light weight, can save the area of transformer station greatly.Be referred to as the GIS cable termination with the terminal of the supporting electric energy transmitting of gas-insulated metal-enclosed formula combined electrical apparatus.
The characteristics of this GIS special-purpose terminal are: compact conformation, stable performance.Because the terminal is in the metal shell, and is closed in SF
6In the gas, so do not receive the ambient atmosphere condition influence.Interior insulation system is generally the dielectric of rubber stress cone filling oiliness, and shortcoming is the hidden danger that has leakage of oil.China's utility model patent: promptly disclose this cable termination in 200520045566.2.
The length of the outlet gold utensil on the GIS dry core cable terminal has two kinds of specifications, that is: that old type is 757mm, and that novel is 470mm.On practical structure, the outlet gold utensil is fixedly connected on the body of terminal, and electric cable accessories manufacturing enterprise normally is the cable termination of making two kinds of specifications in process of production.This production to product, storage, circulation control have brought trouble.
Summary of the invention
For overcoming above-mentioned defective, the technical problem that the present invention need solve is: a kind of GIS dry core cable terminal is provided, and it oil leakage phenomenon can not occur, is convenient to the people in the course of the work for monitoring, to guarantee the stability of its work operation.
Another technical problem that need to solve for invention is: a kind of GIS dry core cable terminal of in production, storage, the process of circulation, managing be convenient to is provided.
For solving said problem, technical scheme of the present invention: a kind of GIS dry core cable terminal comprises 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 requirement that is 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 preset temperature; Transducer promptly produces signal, and 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 through 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, said transducer is a Fibre Optical Sensor, and said lead is an optical fiber.Like this, transducer is little in the influence that the conduction that produces signal and signal is produced by cable termination.
As preferably, the position in stress cone on the said 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 property for body effectively.
As preferably, the position near said epoxy resin bushing on the said body is provided with the spring compression transition apparatus, and this transition apparatus and said 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, said transducer can contact with stress cone well, and this is a sensor in real time, accurately the temperature conditions of perception stress cone provides assurance.
For ease of of the management of this GIS dry core cable terminal, be detachable the connection between said 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, said 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 said body is axially arranged with screwed hole, and the end of said outlet gold utensil is provided with the trip bolt that is connected with said screwed hole.Through the cooperation of trip bolt and screwed hole, realize being fixedly connected between outlet gold utensil and the body, convenient to operation.
As preferably, said stress cone is two kinds of compound processing 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 at terminal GIS cable termination running status.
3, since between outlet gold utensil on the terminal and body for removably connecting, through 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.
