Abstract

The invention discloses a high-voltage large-current coaxial cable connection structure and method. The connection structure comprises a connector, a copper net fixing assembly and a corrugated pipe. The copper net fixing assembly comprises a butt joint pipe, a conical sleeve and an outer sleeve, the conical sleeve sleeves one end of the butt joint pipe, and a conical space for clamping a copper net is formed between the conical sleeve and the butt joint pipe; one end of the outer sleeve is sleeved on the conical sleeve, the inner wall of the outer sleeve and the outer wall of the conical sleeve are provided with matched conical surfaces, and the other end of the outer sleeve is provided with a boss matched with the step; external threads matched with the threaded hole are formed in the middle of the butt joint pipe, and a connecting end is arranged at the other end of the butt joint pipe; and a connecting part detachably connected with the connecting end is arranged at the end part of the corrugated pipe. According to the connection method, the high-voltage large-current coaxial cable connecting structure is connected with one end of the coaxial cable, and the connection method comprises the steps of preparation work before connection, fixing of a copper net and connecting of a corrugated pipe. The connection structure is high in strength and reliability, and the connecting performance of the connecting position can be guaranteed.

Description

technical field [0001] The application belongs to the technical field of cable connection, and in particular relates to a high-voltage and high-current coaxial cable connection structure and a connection method. Background technique [0002] In order to increase the pulse power of high-power pulse devices, it is necessary to reduce their loop inductance. Coaxial cables are often used to transmit large pulse currents to the load, and the transmitted pulse currents are as high as tens or even hundreds of kiloamperes. In the specific application of the shock wave generated by the electric explosion of the metal wire, the energy converter of the same type needs to go deep into the inner working of the borehole. The patent "A Large-Current Transmission Coaxial Drill Pipe" with the application number CN201810575812.7 discloses a segmented coaxial high-current transmission method. Although it has many advantages in its application field, the two-stage coaxial There are the followi...
