Puncture cable clamp

Abstract

The invention provides a puncture cable clamp which comprises a puncture cable clamp which comprises a fixed bracket component and an insulation puncture power taking component arranged on the fixed bracket component. The fixed bracket component comprises a fixed bracket, at least two sliding blocks, and elastic pieces with the same number of the sliding blocks. The fixed bracket is provided with sliding grooves which are matched with the sliding blocks. The sliding grooves are arranged along the radial direction of the fixed bracket. The elastic pieces are arranged in the sliding grooves and are used for allowing the sliding blocks to generate outward expansion trend. The invention provides the puncture cable clamp and aims to combining the puncture cable clamp and a Rogowski coil into a whole body through a locking mechanism formed by the sliding blocks and the elastic pieces, cable with different diameters can go through the center of the coil, the sampling precision is improved, the cost of individually assembling puncture cable clamp is saved, in the condition of no power cut, an operator can carry out power taking in completely safe isolation.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a piercing clip. Background technique [0002] The Rogowski coil is also called the current measuring coil and the differential current sensor. It is a circular coil evenly wound on the non-ferromagnetic material, and 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 measurement of current, fast response, no saturation, and almost no phase error, so it can be applied to relay protection, thyristor rectification, frequency conversion speed regulation, resistance welding and other signal distortions and electric furnaces, Short-circuit test, lightning signal acquisition and other high-current occasions. [0003] The piercing clamp can pierce the insulator of the wire and have good contact with the c...

AI Technical Summary

Problems solved by technology

[0004] Due to the needs of some specific occasions, it is necessary to configure the piercing wire clip and the Rogowski coil at the same time, but when the existing piercing wire clip is used in conjunction with the Rogowski coil, the piercing wire clip and the Rogowski coil are installed separately, and the Rogowski coil and the piercing wire clip installed separately It cannot be guaranteed that cables of different wire diameters pass through the center of the Rogowski coil, which affects the measurement accuracy, and the two installed separately cannot be combined into a whole, and the cost of a separate piercing clip is very high
