摘　　要：探讨了电气二次回路接线核查方法,提出了光纤核线法。通过测试装置将信号源的电信号发送给感应装置,感应装置的接口端Ⅰ将接收到的电信号转化为光信号,并将光信号传输给电缆中的线芯本侧;感应装置的接口端Ⅱ将线芯对侧返回的光信号转为电信号发送给测试装置,测试装置将发送的电信号与返回的电信号进行比对,进而确定本侧线芯对应的对侧线芯,完成二次回路接线核对工作。实践证明,采用该方法后的核对过程减少了工作人员负担,工作效率高、经济性好。The wiring check method of electrical secondary circuit was discussed,and the fiber check method was proposed.The electrical signal of the signal source was sent to the sensing device through the test device.The interface terminal Ⅰ of the sensing device converted the received electrical signal into an optical signal,and transmitted the optical signal to the core side of the cable.The interface terminal Ⅱ of the sensing device converted the optical signal returned from the opposite side of the core into an electrical signal and sent it to the test device.The test device compared the sent electric signal with the returned electric signal,and then determined the opposite core corresponding to the current core,and completed the secondary loop wiring check.Practice proved that the verification process after adopting this method reduced the burden on the staff,and the work efficiency was high and the economy was good.
