       本公司自主研发的UHF传感器采用一体化设计,结构简洁、尺寸小巧,可实现非侵入式带电检测方式,广泛适用于各种电力监控现场。UHF传感器具有高灵敏度、高抗干扰性、宽频带特点,接入后端的测量设备进行处理传输(包含滤波、检波、调理、数字化,识别、远传),以便对运行电力设备进行在线或者巡检监控。
       局部放电(PD)是由于用户电气高压绝缘系统的缺陷而发生的故障之一,用户需要局放测量来监控设备状况并避免故障。当GIS内部产生局部放电现象时,产生的超高频电磁波会沿着管体传播开来,当此信号到达盘式绝缘子时,信号能量可通过绝缘缝隙向外辐射,UHF传感器可通过接收此高频信号作为判断设备内部局部放电程度的判断依据。

 The UHF sensor independently developed by our company adopts an integrated design, with simple structure and small size. It can realize non-invasive live detection and is widely applicable to various power monitoring sites. The UHF sensor has the characteristics of high sensitivity, high anti-interference and wide frequency band. It is connected to the measuring equipment at the back end for processing and transmission (including filtering, wave detection, conditioning, digitization, identification and remote transmission), so as to carry out online or patrol inspection and monitoring on the operating power equipment.

    Partial discharge (PD) is one of the faults that occur due to the defects of the user’s electrical high-voltage insulation system. The user needs partial discharge measurement to monitor the equipment condition and avoid faults. When partial discharge occurs in GIS, the generated UHF electromagnetic wave will spread along the tube. When this signal reaches the disc insulator, the signal energy can radiate outward through the insulation gap. The UHF sensor can receive this high-frequency signal as the judgment basis for judging the degree of local discharge inside the equipment.
