Description
Technical Field
The invention relates to the technical field, in particular to a novel seamless splicing fitting.
Background
At present, the power line terminal tower (pole), the transformer substation inlet and outlet wires and the urban cable line outdoor terminal are mostly connected with an overhead conductor by wire noses, the tail ends of the two wire noses are connected through bolts, and the wire and the cable at the head end are connected by crimping ends in a crimping mode. The existing splicing fitting at the connecting point of the wire and the cable head of the hybrid transmission line is connected by a bolt at the joint of two wire noses, the bolt is easy to loosen when the wire is operated for a long time, the contact area of the connecting part is small, so that the contact resistance is not uniformly distributed, and the heating problem is easy to occur at the connecting point of the wire noses of the line; the power failure treatment is needed in time after the heating, the wire nose is detached to remove an oxidation film and coat the conductive paste for continuous use, the cable accessory is seriously heated and even needs to be replaced, and the power failure time and the cost required by the whole process are greatly increased.
Analysis of the conduction current of the wire and cable and the wire nose: the effective contact area of the tail end of the wire nose and the wire is much smaller relative to the crimping position, and the contact area is only about 25% of the horizontal wire area of the crimping point seen from the side surface, namely, only the edges of the tail end holes of the wire nose are mutually contacted to participate in current conduction, and the bolt only plays a role of pressing under the general condition; when the load current is too large, namely the current flowing through the wire nose is the rated current of the electric wire and cable, the bolt participates in conducting the current, however, the bolt is easy to rust, the bolt is not well contacted with the tail end hole of the wire nose (the bolt only plays a fastening role), and due to the fact that the expansion coefficient of the iron bolt, the expansion coefficient of the copper cable and the expansion coefficient of the aluminum conducting wire are different, under the environment of external application, the pressure of the bolt is loosened due to cold and hot changes of temperature, and the contact resistance is increased. Therefore, the excessive current causes the contact portion of the bolt with the end of the wire nose to generate heat, which further oxidizes the bolt to rust and the wire nose portion to form an oxide film to further increase the contact resistance. Thus, the heat generation is further increased and the oxidation is more serious. The circulation leads to the melting and burning of the wire nose, so that the cable accessories or the wires are burnt. Therefore, with the wire noses, problems each occur at a portion where both wire nose ends contact. It is found from the two wire noses which are actually removed that failures occur at portions where the ends of the two wire noses contact, and the load of the incoming line cannot be excessive for the hybrid power line connected using the wire noses. If the heat is not processed in time after being heated, the safe and reliable operation of the power grid can be influenced, the transmission capacity of the power grid is reduced, and system obstacles and power failure accidents can be directly generated seriously; and power failure treatment is needed in time after heating, the wire nose is detached for replacement or the oxide film is removed and coated with conductive paste for continuous use, and the power failure time required in the whole process is 7 hours. Not only the power supply reliability of the area is reduced, but also a large amount of electric quantity loss is caused, and great construction risks are caused in the construction process.
To above problem, now develop one set of gold utensil device that can the multiple spot use, the special messenger is used for power grid power cable and wire tie point to be connected, prevents that power grid power cable and wire tie point from being connected the unreliable emergence of generating heat, the power failure accident that arouses.
