摘要:

根据GB/T 4473—2018《高压交流断路器的合成试验》中关于共箱式断路器的试验要求,结合中国电力科学研究院高压开关试验站试验设备、控制测量设备、试验场地等具体情况,决定采用适合本试验室的所有相电流引入的三相合成试验线路。针对三相共箱式断路器进行的短路电流开断试验T100s(b),分析计算中性点非有效接地条件下首开及后开瞬态恢复电压值,利用仿真模型对回路各参数进行仿真验证,仿真结果满足标准要求。

Abstract:

According to the testing requirements for common tank circuit breakers in the national standard GB/T 4473—2018“Synthetic Testing of High-Voltage Alternating Current Circuit-Breakers”,and taking into account the specific conditions of the testing equipment,control and measurement equipment,and testing site of the high-voltage switch testing station of the China Electric Power Research Institute,it was decided to use a three-phase composite testing circuit suitable for all phase currents introduced in this laboratory.The short-circuit current breaking test T100s(b)of a three-phase common tank circuit breaker was focused on.The transient recovery voltage values for the first interrupting and subsequent interrupting phases under the condition of a noneffectively grounded neutral point were analyzed and calculated.The simulation model was used to verify the parameters of the circuit,and the simulation results meet the standard requirements.

Key words: common tank circuit breaker, three-phase synthesis test, parameter calculation, simulation
