| Abstract: | Environmental factors bring about many problems to temperature test accuracy and uncertainty in power cabin under environment of strong electromagnetic interference. In order to accurately study on temperature distribution, as far as possible to reduce effects of environmental factors, problem of electromagnetic interference restraining must be solved. According to characteristics of circuit design of temperature measuring system, design electromagnetic interference suppression circuit module, propose a new scheme to restrain electromagnetic interference effectively, it has been applied in practical engineering and had certain practicality, it satisfy high precision temperature measurement in power cabin. |
