摘要
对开关合闸电阻及康铜线电阻材料进行了分析计算,设计并实现了以康铜线作为材料的10 kV馈线短路电阻器。该电阻器具有热容量大、耐受电流高、耐受电流持续时间长的特点,可将短路电流限制到一定范围内。通过将电阻器接入被测线路的两相之间,真实地模拟馈线相间短路故障,从而对配电自动化系统进行测试。
The resistance material such as closing resistor of circuit-breaker and constantan wire is analyzed and calculated. The constantan wire as material of 10 kV feeder short-circuit resistor is designed and implemented. The short-circuit resistor has the characters of large heat capacity, high withstand current, long duration of withstand current. Short-circuit current can be limited to a certain range, through the resistor connected to the line being tested between two phases, true short-circuit fault occurred can be found, thus the distribution automation system can be tested.
