Study on Noise Source Contribution of Converter Cabinet Based on Transfer Path Analysis Test

Abstract There are fan noise and transformer sources inside the converter cabin which may bring environmental pollution through airborne or structural borne paths. In order to identify contribution of each source its path, transfer path analysis test was performed. Take full load working condition at speed as an example, contributions air noise, 88.33%, 3.79%, 7.37% 0.51% respectively. The is 95.70% more than that 4.30%. end aerodynamic simulation compared with experimental result in good coincidence, this can also verifies result.
