Abstract
The invention provides a distributed-capacitance-type intelligent line fault finder and especially relates to the distributed-capacitance-type intelligent line fault finder capable of intelligently finding a fault when the fault occurs and applied to a power distribution board of a rural comprehensive power distribution station area. When lines operate normally, a separation arithmetic unit measures distributed capacitance between phase and phase as well as between phase and ground during normal operation, and the measurement results are stored to the separation arithmetic unit; when one fault occurs, the separation arithmetic unit can calculate and obtain the fault type and fault distance by measuring the distributed capacitance between phase and phase as well as between phase and ground through a detection connecting line and comparing the measured result with the data stored in the separation arithmetic unit, and gives Chinese character reminding information on an operation display screen; and maintenance personnel are allowed to find the fault point quickly according to the Chinese character reminding information so as to carry out maintenance and power restoration, and thus the purposes of quickly finding the fault type and fault distance as well as finishing maintenance in a short time are realized. The distributed-capacitance-type intelligent line fault finder is reasonable in structure, good in use effect, low in manufacture cost and easy to be widely applied.
