Abstract

The invention provides a test device for a current sensor. The test device for the current sensor comprises a mounting rack and a control box. The mounting rack comprises a bottom plate, a left support, a right support, a copper bar connecting the left support and the right support, and a left adjustment handle and a right adjustment handle which are arranged on the copper bar, wherein the left support and the right support are mounted on the bottom plate; the left adjustment handle and the right adjustment handle are used for tightening or loosening the copper bar; and multiple current sensors can be mounted on the copper bar. The control box comprises a voltage test module, a power supply module and a current source module, wherein the power supply module is connected with the current sensors and is used for providing power to the current sensors; the current source module is connected with the left support and the right support and is used for powering on the copper bar to provide aprimary side bus current to the current sensors; and the voltage test module is connected to the sensors and is used for measuring output voltage of the current sensors. The test device has the advantages of high test efficiency.

Description

technical field [0001] The invention relates to the field of testing devices, in particular to a testing device for a current sensor. Background technique [0002] Current sensors are widely used in various fields such as industry, automobiles, transportation, and new energy. Current sensors are divided into open-loop and closed-loop structures. With the advancement of science and technology, the continuous improvement and development of high-speed rail technology, the successful research and development of high-end smart meters, and the continuous advancement of intelligent manufacturing, the requirements for the accuracy and performance of sensors are constantly improving, so the requirements for the performance and efficiency of corresponding test devices are also increasing. come higher. The traditional test method is to use a copper rod as the primary terminal of the current sensor to provide the current sensor with the bus current of the primary side. The wrench is l...
