Converter valve assembly loss measuring device

The invention provides a converter valve assembly loss measuring device, and belongs to the field of electrical performance testing devices. The measuring device comprises a box body, the box body is internally provided with a setting space for setting a converter valve assembly, the box body is connected with an air inlet duct and an air outlet duct, and the air inlet duct or the air outlet duct is provided with a fan; the converter valve assembly loss measuring device further comprises an air inlet temperature sensor used for detecting the temperature of air entering the box body, an air outlet temperature sensor is installed in the air outlet duct, and an air volume tester is further installed in the air inlet duct or the air outlet duct so as to calculate heat dissipated by the converter valve assembly through air. Loss of the converter valve assembly is transmitted to air in the setting space in a heat mode, then the air in the box body rapidly flows in the set direction, energy consumed by the converter
