Abstract

The application discloses a distributed ultra-high-frequency (UHF) sensor. The distributed ultra-high-frequency sensor includes: a sensing unit, which is used for collecting a target signal, which isgenerated by partial discharging, when partial discharging of power equipment occurs, wherein the target signal is any one of the following items: an ultra-high-frequency electromagnetic wave signal and an ultrasonic signal; a micro-strip patch antenna, which is packaged in the distributed ultra-high-frequency sensor, and is used for communication connection on the distributed ultra-high-frequencysensor and a detection terminal; a signal processing unit, which is used for processing the collected target signal; and an AD conversion module, which is connected with the signal processing unit, and is used for converting the target signal, which is output by the signal processing unit, into target data. Through the sensor, the problem that cable monitoring systems in related technology cannotmeet higher monitoring requirements in cases where feeding networks are complex and widely distributed, and low cable monitoring efficiency is caused is solved.

Description

technical field [0001] The present application relates to the field of cable detection, in particular, to a distributed UHF sensor. Background technique [0002] In related technologies, with the continuous improvement of the level of industrialization and urbanization in our country, the demand for power has also increased sharply, and the requirements for the safety and stability of the power system have also become higher and higher. Because of the characteristics of easy installation, high electrical strength and small dielectric loss, power cables can effectively solve the problems of urban power consumption aggregation effect and excessive land occupation of overhead lines. It has been rapidly promoted in the power grid, and power cables have developed into important equipment for power transmission at various voltage levels. They play an indispensable role in the safety of power loads and reliable power transmission. Partial discharge monitoring of power cables is an...
