Abstract:

DC miniature circuit breaker (MCB) is used to provide overload,short circuit,overvoltage and undervoltage protection for clean energy system and various DC loads.Based on that the DC circuit has the characteristics of reasonable selection of critical load current and time constant,this paper starts from the development of DC MCB,first combs the application scenarios of DC MCB,combining with the test situation and test data of key tests,expounds and analyzes its design principle,structural design points,material selection,grounding mode and development trend.

Key words: clean energy, DC load, application scenario, terminal protection, DC MCB
