Abstract

A power line carrier radiation detection ring assembly comprises a detection ring and a winding, the detection ring is formed by hinging a first semi-ring and a second semi-ring, the winding is woundon the detection ring, is a twisted pair and is formed by mutually winding a first wire and a second wire, the twisted pair is divided into a first wire and a second wire by the branching module at the tail ends of the first semi-ring and the second semi-ring, the first wire and the second wire enter from the wire inlet hole and extend out from the wire outlet hole respectively, the two ends of the first wire are connected with the input end, the two ends of the second wire are connected with the load, and the load is used for filtering interference waves from the outside. When the detection ring works, the detection ring is directly sleeved on a power line for radiation detection, and the effect of radiation detection is much higher than that of a traditional power line carrier detectionantenna due to large contact area and load filtering interference waves.

Description

technical field [0001] The invention relates to the technical field of power carrier radiation detection, in particular to a power carrier radiation detection loop assembly. Background technique [0002] Power carrier is a unique method in the power system. The realization of power carrier is the technology of high-speed transmission of analog or digital signals through the use of existing power lines. When power carrier is connected to terminal equipment, electromagnetic signals will be generated and transmitted through power lines. , and this electromagnetic signal will radiate to space through the power line. By detecting this radiation signal, the connectivity status and physical distribution of the power line can be evaluated. However, the electromagnetic radiation generated when the power carrier passes through the wire is relatively weak, coupled with the interference of external electromagnetic signals, the effect of directly detecting the radiation generated by the...
