Embodiment

[0038] refer to figure 1 The corona discharge positioning device includes an array antenna sensor 100 , a switching circuit 200 and a processor 300 connected in sequence.

[0039] refer to figure 2 , the array antenna sensor 100 includes an arc structure 120 and a plurality of antenna coils 110 arranged at equal intervals arranged on the arc structure 120 . Specifically, a plurality of antenna coils 110 are arranged at equal intervals in all directions along the outer surface of the arc surface of the arc structure 120 . The direction of each antenna coil 110 is perpendicular to the arc structure 120 .

[0040] And, if image 3 As shown, the antenna coil 110 has a helical structure; the helical antenna is used to receive electromagnetic pulse signals because of its flat characteristic impedance, good circular polarization characteristics, and superior electrical performance of end-fire and side-fire performance.

[0041] The number of antenna coils 110 here is at least fo...

Description

technical field [0001] The invention relates to the technical field of power system operation monitoring and measurement, in particular to a corona discharge positioning device and a positioning drone. Background technique [0002] Corona discharge is a discharge phenomenon that occurs due to the high electric field intensity on the surface of the wire, which causes air ionization. Corona discharge produces high-frequency pulse currents, which cause electromagnetic interference to radio communications, cause chemical reactions in the air, cause damage or corrosion to solid media and metal electrodes, accelerate the aging of composite insulators, and generate energy loss, etc. [0003] Corona discharge is the focus of attention in power systems. To solve the corona discharge, the first problem is to determine the location of the corona discharge. Contents of the invention [0004] In view of this, the object of the present invention is to provide a corona discharge positi...
