An Open Type Rogowski Coil Current Sensor Convenient for Mounting at High Places

Abstract

The invention discloses an open-type Rogowski coil current sensor which is convenient to be mounted at a high place. ; The hanging support rod is a hollow structure, one end of the telescopic inner support rod is sleeved in one end of the hanging support rod, the other end of the telescopic inner support rod is connected with one end of the connecting rod, and the side surface of the other end of the connecting rod is It is connected with one end of the main support frame and the fixed pulley, and the connecting rod is provided with a clamping slot along the axial direction, and one end of the push plate is clamped in the clamping slot; one end of the rope is fixed on the push plate, and the other end of the rope After the fixed pulley is fixed on the other end of the hanging strut, the signal transmission line is connected with the output end of the current sensor. The user can stand at a low place and suspend the current sensor of the present invention to a high place, and the operation is simple and the safety is high.

Description

technical field [0001] The invention relates to a current sensor, in particular to an open-type Rogowski coil current sensor which is convenient to be mounted at a high place. Background technique [0002] With the continuous development of electrical measurement technology, the current sensor has become a common current detection device, which can sense the information of the measured current, and transform the information sensed by the detection into an electrical signal or Other required forms of information output to meet the requirements of information transmission, processing, storage, display, recording and control, etc. Among them, the Rogowski coil current sensor uses electromagnetic induction as the mechanism, and under the action of the changing circular magnetic field, the induced The electromotive force is transformed into the current output equivalent to the measured lead through the integrating circuit. Because of its stable performance, simple structure, conv...

Problems solved by technology

[0003] But usually the through-hole Rogowski coil current sensor is a jaw type, which can only be stuck on the current-carrying line of the tested circuit at a low or grounded place by manual operation. Climbing on ladders or aerial operations with slings to mount sensors will increase certain work steps and processes as well as manpower, and at the same time increase safety risks
