It is, comprises the following steps：
1) the online pulling force detector of high voltage cable is fixed by cable clamp (2) with cable, and makes line of the cable from its two ends
Cable ring (3) is passed through, and pulling force detector is connected with ground monitoring unit using wireless mode；, then tense cable so that cable by
Tension tautness；
2) the stress point height value H1, the height value H2 and the side line of cable clamp two of cable rings of cable clamp on pulling force detector are measured
The distance between cable ring value L, can obtain cable pulling force according to Newton's law and act on the mathematics modulus of conversion of cable clamp partial pressure
Type is：Wherein T is value of thrust suffered by cable, and F is that pressure sensor is detected
Pressure value；
3) central processing module receive pressure sensor signal, based on step 2) principle, calculating processing after by wirelessly passing
Defeated module is transferred to ground detection unit；
4) according to step 2) mathematics transformation model and with reference to DL/T5092 designing technique codes, calculate pressure sensor
Maximum range, and by its typing ground monitoring unit；
5) the cable value of thrust T for being connected to the shaft tower obtained by detection is transferred to ground monitoring list by wireless transport module
Member, and maximum corresponding with the model cable is born pulling force and is compared in ground monitoring unit, and shaft tower can be monitored in real time
Bear pulling force situation.
10. the detection method of the detecting system of the online pulling force detector of high voltage cable according to claim 9, its feature exists
In：In step 1) in, the cable clamp (2) is occupy in the middle of two cable rings (3)；For anchor support and turning tower, in tension
The high voltage cable online pulling force detector is installed on the electric wire that wire clamp goes out；For tangent tower, in the two ends cable of tangent tower
It is upper that the online pulling force detector of high voltage cable is installed.
