Abstract

An openable and closable clamping support of a flexible Rogowski coil is used for clamping the flexible Rogowski coil and at least comprises an annular support body and a damping device arranged on the annular support body. The annular support body comprises an annular shell and an elastic chuck; and the damping device comprises a driven insertion piece, a transverse sliding rod, a sliding device and a damping insertion cylinder. An opening and closing method of the openable and closable clamping support of the flexible Rogowski coil is characterized by comprising the following steps: 1, closing, half-opening and full-opening; and 2, changing of the rotation damping of a front half ring. According to the openable and closable clamping support of the flexible Rogowski coil and the opening and closing method thereof, the openable and closable clamping support is arranged on a tested element in a sleeving mode and used for clamping and fixing the flexible Rogowski coil, the structure is reasonable, and operation is easy; the damping insertion cylinder and the sliding device can assist the annular shell to achieve the effect of complete closing or automatic complete opening; and the operation damping of the damping insertion cylinder can be further adjusted, namely the damping generated when the front half ring is rotated is adjusted.

Description

technical field [0001] The invention relates to the technical field of Rogowski coils, in particular to an opening and closing method suitable for a flexible Rogowski coil openable and closable clamping bracket. 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 installed...
