Embodiment Construction

[0076] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0077] An openable and closable clamping bracket for a flexible Rogowski coil, used to clamp the flexible Rogowski coil m, at least including an annular frame body and a damping device arranged on the annular frame body;

[0078] The ring frame includes:

[0079] The annular shell a is circular, and the annular shell a includes a semi-annular rear half-ring a-1, and a front half-ring a-2 hinged on the left front of the rear shell a1;

[0080] The elastic collets b are evenly distributed on the upper end surface of the annular shell a in the circumferential direction, and the elastic collets b include a collet longitudinal rod arranged upwardly from the upper end face of the annular shell a, arranged on the upper end of the collet longitudinal rod and along the The annular shell a is radially away from the chuck cross bar of the axial center of the annular sh...

Abstract

An openable and closable clamping bracket for a flexible Rogowski coil, used for clamping a flexible Rogowski coil, at least includes a ring frame body and a damping device arranged on the ring frame body; the ring frame body includes a ring shell, an elastic clip head; the damping device includes a driven insert, a horizontal slide bar, a sliding device, and a damping insert; an opening and closing method for an openable and closable clamping bracket of a flexible Rogowski coil, which is characterized in that it includes the following steps: Step 1 , close, half-open, fully open; step 2, change of the rotational damping of the front half-ring. The invention provides an openable and closable clamping bracket for a flexible Rogowski coil and an opening and closing method thereof, which is sleeved on a measured element to clamp and fix the flexible Rogowski coil, and has a reasonable structure and simple operation; the damping insert and the The sliding device can assist the annular shell to realize the effect of fully closing or automatically fully opening; it is also possible to further adjust the running damping of the damping insert, that is, adjust the damping when rotating the front half ring.

Description

technical field [0001] The invention relates to the technical field of Rogowski coils, in particular to an openable and closable clamping bracket of a flexible Rogowski coil and an opening and closing method thereof. Background technique [0002] Rogowski coil, also known as current measuring coil or differential current sensor, is a toroidal coil evenly wound on a non-ferromagnetic material. 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. [0003] Because Rogowski coils are made of soft materials, sometimes rigid materials can be used to make clamping brackets, which can be fixed on the measured element and support the Rogowski coils to maintain a stable attitude of the Rogowski coils. The patent of authorized notification number CN205333717U discloses a Rogowski coil fixing frame, but the fixing frame is cumbersome to install and cannot be inst...
