Come, and scram is realized to cableway control PLC by I/O interfaces output alarm signal.
The present invention principle be：
1st, the present invention is detected come the winding of touching for carrying out steel wire rope based on the principle of traveling-wave protection.
Using two steel wire ropes as two conducting wires, apply specific ac supply signal, when certain point F sends out on circuit
Can be analyzed using principle of stacking during raw short circuit (steel wire rope is contacted and wound).Therefore, Fig. 1 (a) can be equivalent with Fig. 1 (b), enters
And Fig. 1 (b) can be considered normal duty component Fig. 1 (c) with fault component Fig. 1 (d) superposition of the two.Due to travelling wave ranging it is only anti-
Time extremely short fault transient component signal is reflected, therefore fault transient component signal is only discussed.From Fig. 1 (d), fault component
When being zero equivalent to system potential, one is added at the F of trouble point equal in magnitude and in opposite direction with the normal duty state
Voltage.
It is assumed that line parameter circuit value is uniformly distributed along the line, and the impact of negligible resistance and conductance, that is, think that electric wire is uniform lossless
, the equivalent circuit of its solid conductor is as shown in Figure 2.In Fig. 2, circuit unit length inductance and electric capacity are respectively L and C, then in Δ

Calculating, Fig. 4 (b) is both-end traveling wave positioning schematic.
If tm, tnRespectively the initial traveling wave of failure reaches the moment of m sides and n side bus, then have
In formula, v is traveling wave spread speed, and Δ t receives the time difference of initial traveling wave for both sides.Local terminal is measured after failure
To time pass to opposite end, two ends can calculate fault distance.
The present invention calculates the distance of trouble point F to M ends or N-terminal using single-ended traveling wave detection and localization principle.
