Embodiment
Following structure drawings and Examples are further described the utility model.
As shown in Figure 1.
A kind of ground buried pipeline burglar alarm reach formula induction band, it is made up of with the resistance 2 that the some resistances that are attempted by on this lead group equate the lead group that two one group lead 1 is formed at least, described lead group is fixed on to be had in the flexible strip insulation base material 3, resistance 2 can fixedly be in the insulating substrate 3, also can take insulation measures to be placed between the section and section of adjacent insulating substrate 3.In addition, in order to tackle complicated environment for use, the utility model in the surface applied of insulating substrate 3 can bear the cuticula of 7000V voltage strength.
Fig. 2 is a concrete application examples of the present utility model, 4 is pipelines among Fig. 2, the 5th, the wired adhesive tape of the warning effect of also playing that principle of work is identical with the utility model, the generation of the accident of failing to report that causes to prevent the part offender from when punching, not destroying induction band of the present utility model.
Principle of work of the present utility model is:
As shown in Figure 3.
Induction band of the present utility model just is equivalent to the resistance 2 of dose known amounts and resistance and (establishes the resistance number=n that incorporates into, the resistance=R of resistance
0), the circuit of the parallel resistance that constitutes according to known spacing (or geographic coordinate).If the resistance of each resistance 2 all equates=R
0, the spacing between each resistance 2 represents that with L the resistance item nearest from the monitoring station is 1, is n from the item of supervising station resistance farthest, then:
Length overall=the L of protected pipeline section
1+ L
2+ ... + L
N-1+ L
n
The monitoring all-in resistance R of this pipeline section
T=R
0/ n, R
0=nR
T
Suppose that the unprincipled fellow is arranged, when certain of protected pipeline section was stolen on a bit, it must break ground and destroy the outer anticorrosive coat of pipeline earlier, the sensing silk will be cut off.Be between the resistance that item is x and x+1 if steal point, then the all-in resistance measured of supervising device has not been No. 1 all-in resistance to the n parallel connection, but arrives x parallel resistor value No. 1, that is:
Monitored resistance R
x=R
0/ x=nR
T/ x then,
Steal the resistance item x=nR of point
T/ R
