Abstract

The invention provides a high-frequency 3M circular test tool of a tri-coaxial cable shielding effectiveness test system. The tri-coaxial cable shielding effectiveness test system comprises a vector network analyzer and the high-frequency 3M circular test tool. The high-frequency 3M circular test tool comprises an outer loop near-end short-circuit structure, a shielding cap structure and a metal cylinder structure, and the outer loop near-end short-circuit structure comprises a left end cover and a short-circuit clamping piece; the shielding cap structure comprises an inner loop far-end shielding box, an outer loop far-end assembly, a supporting assembly and a connector. The metal cylinder comprises a first outer copper pipe and a second outer copper pipe.

Description

technical field [0001] The invention belongs to the field of electrical measurement technology and instruments, in particular to a three-coaxial method cable shielding effectiveness testing system. Background technique [0002] There are domestic research patents related to the evaluation of cable shielding effectiveness distributed in the fields of electric vehicles, aerospace, ships, etc., and there are few high-frequency band test systems based on the triax method for RF coaxial cable shielding effectiveness. In the field of high-voltage shielded cables for rail transit Also in the blank area. [0003] With the continuous emergence of various communication services, the development of high-frequency communication has become a trend. The demand for broadband communication has become the driving force for the development and innovation of coaxial cables. High-frequency communication has put forward higher requirements for coaxial cables that transmit radio frequency signals...
