Description
Technical Field
The invention relates to the technical field of electric appliances, in particular to a cylindrical electric power connecting wire clamp.
Background
With the development of modern society, the requirements of users on power supply reliability are higher and higher. The distribution network is responsible for the task of supplying and distributing electric energy to various users in situ or step by step, and is the most direct and critical link for ensuring the power supply quality. To meet the requirements of mechanical and electrical performance, various types of electrical connectors are continuously developed, and the wire connecting clamp is one of the more widely used types. The adoption of the wire clamp as a hot technology for the drainage operation of the distribution network line has achieved a certain degree of success in practical application, but in recent years, under the dual effects of urban development and economic construction, the life and engineering electricity consumption are greatly increased, and the reliability of the wire clamp is severely challenged. The main failure mode of the lead wire clamp is electric contact failure, wherein the electric contact failure is mainly represented by sharp rise of contact resistance, and the load causes serious heating and even burning. According to related investigation data, the failure rate of the 10kV distribution line accounts for about 70% of the failure rate of the whole network, and the failure rate of the connecting wire clamp accounts for the highest in the failure of the 10kV distribution line, so that serious economic loss and personal safety are caused. In recent years, as the power consumption increases, the circuit load increases, the T-contacts increase, and the lead clamps overheat, which has serious potential safety hazards. Based on the above, the high-reliability and long-service-life wire connecting clamp is definitely an important guarantee for modern efficient power transmission.
The lead wire clamp is applied to a plurality of 10kV distribution lines, such as a C-shaped wire clamp, a puncture wire clamp, a parallel groove wire clamp and the like. The operation purpose of the lead wire clamp is to finish the lead wire connection work of the main overhead transmission line drainage wire in the uninterrupted operation, compared with the traditional line lead connection technology, the use of the lead wire clamp has the advantage of being more matched with the power supply form of a line, and meanwhile, the uninterrupted operation mode of the lead wire clamp creates great economic benefits for power supply enterprises. The parallel groove clamp which is popular in the early stage because of good current carrying capacity adopts bolts to bear the locking task, and the bolts inevitably have the phenomena of creep, loosening, breakage and the like after working for a long time under wind vibration, temperature difference and other complex outdoor environments due to the structural characteristics of the bolts, so that the safety accident occurs, and the maintenance cost is huge. In recent years, the puncture clamp introduced from abroad has simple construction operation, can be directly installed without peeling, but also easily causes too deep puncture to hurt a conductor or insufficient puncture, and the adopted needle point type contact has smaller contact surface and weak current carrying capacity, so that a plurality of potential safety hazards still exist in actual use. So far, the connection mode of the C-shaped wire clamp is generally accepted, and the C-shaped wire clamp is reasonable in design, high in current carrying capacity and self-locking in an ideal state. However, in the actual use process, due to the fact that the size of the wire clamp and the outer diameter of the wire are slightly deviated, when the outer diameter of the conductor of the wire is slightly smaller, a certain gap is formed between the wire clamp and the wire, and poor contact is caused. When the outer diameter of the conductor of the wire is bigger, the installation of the wire clamp and the wire cannot be flattened and self-locking cannot be realized. Furthermore, the C-shaped wire clamp has forty types and specifications, which causes difficult rush repair and large spare parts.
