Device and method for testing thermal electromotive force of shunt

Abstract

The invention provides a device for testing the thermoelectromotive force of a shunt. The device comprises a heating module, a heat dissipation module, a control module, a data acquisition module, a data analysis module, a display module and an alarm module, the heating module and the heat dissipation module are connected to manganese-copper weld joints on the left side and the right side of a product correspondingly, and the control module is electrically connected with the heating module and the heat dissipation module and used for controlling on-off of circuits of the heating module and the heat dissipation module. The data acquisition module is connected with a product and is used for acquiring surface temperature data of the product and voltage data after electrification and transmitting the acquired data to the data analysis module, and the data analysis module is used for sorting the received data and calculating by using a function to obtain a required test value and then transmitting the required test value to the display module; and meanwhile, the data acquisition module performs comparison control on the obtained test value and a threshold value, when the test value is less than or equal to the threshold value, the next test is automatically performed, and when the test value is greater than the threshold value, the test is judged to be unqualified, the test is stopped, and the alarm module is controlled to output alarm sound and light.
