安全生产是关系人民群众生命财产安全的大事,是经济社会协调健康发展的标志.当前,我国正处在工业化、城镇化持续推进过程中,生产经营规模不断扩大,传统和新型生产经营方式并存,致使各类事故隐患和安全风险交织叠加,生产安全事故易发多发.这些现状无不要求企业在生产经营中重视安全生产工作,而与电气相关的事故,包括触电事故、电路老化引起的火灾事故等正是绝大部分企业在日常生产经营中最常遇到的事故.

The paper mainly introduced the application of TDS3014B oscilloscope in detecting the synchronous waveform of voltage and current of micro breaker.Five to ten times of rated current was loaded,instantaneous disconnection and closure of micro breaker can be detected by TDS3014B oscilloscope.Meantime,disconnection and closure voltage and current of each phase can be measured.
