Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the following embodiments are only used to illustrate rather than limit the present invention.

[0026] A lightning current monitoring centering mechanism module provided by the present invention, such as figure 2 As shown, it includes two symmetrical connectors 61 and 62, the two end surfaces of the two connectors 61 and 62 and the bottom surfaces that fit each other are square, and are fixed by bolts; There are through grooves, and two semi-discs 7 parallel to each other and perpendicular to the square bottom protrude from the other bottom surface of each connecting piece opposite to the attached two bottom surfaces. The clip space forms an annular groove 8 .

[0027] In this embodiment, flat grooves 9 extending longitudinally along the connectors 61 and 62 are provided on the two bottom surfaces that fit together, and a t...

Abstract

The invention relates to a centering mechanism module for lightning current monitoring, which comprises two halves of substantially square connectors, both ends and one bottom of the two halves of the connector are square, and the square bottoms of the two halves of the connector are attached to each other. The combination is fixed by fasteners, and the two square bottom surfaces are centered with through grooves centered on each other, and two mutually parallel and parallel to the square bottom surface protrude from the other bottom surface of each connecting piece. The square base is a vertical semi-circular disc, and the space between the two semi-circular discs forms an annular groove. The invention enables the down conductor to accurately pass through the center of the Rogowski coil, and solves the problem of inaccurate monitoring data in actual monitoring.

Description

technical field [0001] The present invention relates, more specifically, to a lightning current monitoring centering mechanism module. Background technique [0002] Rogowski coil (Rogowski coil), also known as current measuring coil and differential current sensor, is a hollow loop coil evenly wound on non-ferromagnetic material, which is mainly used to measure AC current. The output signal is the differential of the current with respect to time. Through a circuit that integrates the output voltage signal, the input current can be truly restored. The coil has the characteristics of real-time current measurement, fast response, and no saturation, and is suitable for AC, especially high-frequency and large-current measurement. [0003] There are two kinds of Rogowski coils, flexible and rigid, which can be directly placed on the conductor to be measured to measure AC current. The specific working principle is that the coil skeleton surrounds the conductor to be measured, and...
