2、日哈爾濱理工大學學士學位論文IIIntelligent leakage protection device based on SCMAbstractIn recent years, due to the scale of China's economic construction continues to expand, the rapid growth of the use of electricity, electrical

3、 safety issue is very important. In everyday life the principle of power protection equipment due to improper use of electrical or electronic circuit turn is caused by residual current principle. But the presence of the

4、dead zone leakage protection in some cases can not be effectively implemented leakage protection, there is a great security risk. These problems at home and abroad has not been effectively addressed, and therefore need t

5、o study new leakage protection principles, adapt the protection requirements of different situations. Electronic technology advances, considerable development and application of SCM also contributed to the progress

6、 of leakage protection, single-chip technology will be applied to the residual current protection device may improve reliability, achieve more suitable for users of multi-functional protection. Therefore, the use of resi

7、dual current protection chip technology has a strong advantage in terms of function realization.In this paper, the leakage protection technology for the study, through the study of residual current transformer for differ

8、ent types of leakage currents theoretical analysis, uses chip technology hardware and software design, implementation, detection of leakage current, fast processing and display, design of new leakage protection and high
