System and method for testing performance of relay contact based on infrared thermal imaging

Abstract

The present disclosure provides a system and method for testing performance of a relay contact based on infrared thermal imaging, and relates to the field of performance testing of relay contacts. The system includes a collection device, a testing device, and a time relay. The testing device is separately connected to a tested relay and the time relay, and configured to control closing and release of a contact of the tested relay by using the time relay. The collection device is connected to the testing device, and configured to collect a temperature, a closing quantity, and working duration of the contact of the tested relay. The present disclosure resolves a limitation in existing performance testing methods for intermediate relays, which predominantly concentrate on individual parameters like voltage, current, and time, while overlooking the assessment of contact performance.
