摘要:
为了解决轨道交通电力变流器噪声测量没有试验规范可依的问题,提出了一种基于包络法的电力变流器噪声测量方法,该方法适用于大多数实验室并能使不同实验室测量结果之间的复验性标准偏差≤ 3.0 dB(A),在保证试验数据的科学性和准确性的同时有利于不同实验室间噪声测量的能力比对,为电力变流器噪声测量提供了一种切实可行的规范。
Abstract:
In order to solve the problem that there is not test specification for the railway applied power converter noise survey, a method of noise survey for power converter based on the envelope method was proposed. The method was suitable for most of the laboratory and could make the difference between the results from laboratory measurement reproducibility standard deviation less than or equal to 3.0dB(A), which could ensure the scientific and accuracy of test data, at the same time, it was beneficial to compare the capability of noise survey between different laboratories. It also provides a practical specification for noise survey of power converter.
