| 摘 要： | 以单频振荡回路作为实验电源，以不同型号的塑壳断路器作为研究对象，通过不同条件下的开断对比实验，研究了双断点塑壳断路器的开断性能特点，提出了双断点结构在短路开断过程中更容易发生触头熔焊，以及容易出现断口问能量不平衡等特点。 |
| 关 键 词： | 塑壳断路器 双断点 实验研究 |

| Abstract: | Use a capacity bank as power source,experimental observation to the breaking process of several type circuit breakers is executed under deferent conditions,to research characteristics of double-break modeled case circuit breakers(MCCB).As a result it is presented in this paper that double-break MCCBs have some characteristics comparing to single-break MCCBs including: unbalance of switching-arc energy between two gaps is easer to act and,double-break MCCB is easier to fusion welding than single break MCCBs,... |
| Keywords: | modeled case circuit breaker double-break experimental research |
