摘要
介绍了火花试验装置的结构、原理及其在本质安全电路评定中的应用,指出将该装置用于本质安全电路评定时应进行多方面的调整和验证,并指出该装置具有不适用于试验电流大于3 A的电路等局限性。
The paper described structure and principle of spark test device and its application in assessment of intrinsically safe circuit,and pointed out that the device should be adjusted and verified from different aspects while applied to assessment of intrinsically safe circuit,and that the device has limitations such as inapplicability for circuit with testing current greater than 3 A.
