Embodiment Construction

[0056] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0057] Radio interference is the formation of corona current by corona discharge of high-voltage wires, and the corona current propagates in the wires, thereby emitting electromagnetic waves into space.

[0058] In view of the dispersive nature of corona discharge, long-term measurement statistics are required to obtain its regularity; long-term tests are carried out using corona cage test devices. At present, the radio interference test in the corona cage is to obtain the radio interference of the transmission wire by collecting the corona current on the wire coupled to the current signal on the capacitor and inductance in the corona cage test device, and then performing a certain...

Abstract

The invention discloses a patch antenna for measuring television interference, a television interference measuring device and method. The patch antenna for TV interference measurement comprises: a dielectric substrate; a ground plane located on the reverse side of the dielectric substrate; a radiator positioned on the front side of the dielectric substrate, the radiator having a first central symmetrical notch at the upper edge thereof and a second central symmetrical notch at the lower edge thereof; the first center symmetrical notch is symmetrical to the longitudinal center line of the dielectric substrate; the second center symmetrical notch is symmetrical to the longitudinal center line of the dielectric substrate; The first center symmetrical notch and the second center symmetrical notch are symmetrical to a transverse center line of the dielectric substrate. The patch antenna is mounted on the inner wall of the corona cage, which can directly measure the TV interference of the transmission line in space and reduce the measurement error.

Description

technical field [0001] The present invention relates to the technical field of TV interference measurement, and more particularly, to a patch antenna for TV interference measurement, a TV interference measurement device and method. Background technique [0002] The electromagnetic environment effect of UHV overhead transmission lines has attracted increasing attention, and it also involves the feasibility and economy of power transmission and transformation projects. Among them, radio interference may cause interference to surrounding radio stations such as communication, direction finding, navigation and radar stations. Radio interference is the formation of corona current by corona discharge of high-voltage wires, and the corona current propagates in the wires, thereby emitting electromagnetic waves into space. [0003] With the development of radio services, radio frequencies are getting higher and higher, and there are more and more incidents of interference caused by t...
