[0033] The following is attached figure 2 The present invention will be described in detail. figure 2 It is a structural diagram of the device for quickly identifying the fault location of the distribution network line of the present invention, and the labels E0-E9 are respectively corresponding detection devices installed on the circuit breakers D0-D9 (normally, the circuit breaker D7 is disconnected, and other circuit breakers are Closing state), the detection device is used to detect the current flowing through the corresponding circuit breaker, assuming that a short circuit fault occurs in the circuit breaker D4~D5, the position of circuit breaker D4, circuit breaker D3, circuit breaker D2, circuit breaker D1, circuit breaker D0 The fault current can be detected everywhere. At this time, the detection devices E0~E4 generate and send out detection signals after detecting the fault current, and the detection devices E0~E4 are placed in the fault state. The dotted line betw...
