Embodiment Construction
[0022] Such as Figure 1 to Figure 3 As shown, the high-voltage distribution line electromagnetic interference tester includes a box body 1 , an extension bracket 2 and an electromagnetic interference tester 3 . The box body 1 is provided with an extension bracket 2, and an electromagnetic interference tester 3 is installed on the extension bracket 2. The electromagnetic interference tester 3 is an existing device, and will not be introduced too much.
[0023] The box body 1 includes an upper shell 102 and a lower shell 101, which are hinged together. The upper case 102 is further provided with a pull button 103 for locking the upper case 102 and the lower case 101 .
[0024] In an optimized design, magnet pieces are provided on the joint surfaces of the upper casing 102 and the lower casing 101 , and the upper casing 102 and the lower casing 101 are attracted together by the magnetic force of the magnet pieces.
[0025] The extension bracket 2 includes a lower base plate 20...

The invention relates to a high voltage distribution line electromagnetic interference determinator and belongs to the field of distribution equipment. The determinator comprises an electromagnetic interference tester, a casing and a stretching support, wherein the casing is internally provided with the stretching support, the stretching support is equipped with the electromagnetic interference tester, and the casing comprises an upper casing and a lower casing which are connected together. Through the determinator, difficulty in measuring electromagnetic interference and electromagnetic radiation is reduced, and the determinator is suitable for being used by most people. Through the stretching support, measurement work of the electromagnetic interference tester can be more conveniently carried out, the framework formed by the stretching support is suitable for being taken as a shielding region, electric power work personnel of high voltage lines is convenient to dispose related equipment in the shielding region, interference of the high voltage lines on the equipment can be avoided, and small-distance position change of the tester can be realized through the buffer effect of a cylinder.
Description
technical field [0001] The invention relates to the field of electrical distribution equipment, in particular to an electromagnetic interference measuring instrument for high-voltage distribution electrical lines. Background technique [0002] With the development of science and technology and productivity and the improvement of people's living standards, the types of man-made interference sources are increasing, and the electromagnetic interference generated is increasingly polluting the environment. At present, man-made interference has become the main source of electromagnetic environment level. From the way of transmission of interference, electromagnetic interference can be divided into: conducted interference and radiated interference. Electromagnetic disturbances transmitted along wires are called conducted disturbances. Radiated interference refers to electromagnetic interference that propagates through space. [0003] Electromagnetic interference is very harmful ...
