英文摘要：

Hybrid circuit breakers which take advantage of the traditional switch and overcome their shortcomings are the development trend and research hotpot of future smart grid. Consequently, we discussed the development and research status of hybrid circuit breakers at home and abroad, and classified hybrid circuit breakers based on their structure and operating principle. Moreover,we reviewed the operating principle, structure, and application fields of hybrid circuit breakers based on vacuum and SF_6 in series and based on power electronic. The dynamic insulation characteristics, operation precision and the optimal synergy control strategy of the HCB with series-connected VCB and SF_6 circuit breaker should be deeply investigated in order to promote its application in the field of high voltage and large current. The key technology of HCB based on the power electronics is vacuum arc commutating characteristic, fast actuator and breaking control strategy. This type of HCB will be used in low-voltage DC breaking.
