and the tangential plane is aligned to mark the tangential plane, and whether the alignment is completed is judged according to the coincidence rate of the marks of the two tangential planes in the alignment.
In practice, the cable alignment unit determines that the cables are aligned by uniformly marking the cable sections, and marking the overlapping number to be higher than 90% on Ji Shibiao;
when the connector connecting unit works, the connector is arranged at the aligned cable connection position, and the bolts are used for applying pressure to the conductors of the cable for connection and fixation.
Referring to fig. 3, a schematic diagram of a second connection mode of an explosion-proof module of a military high-voltage cable connection system according to an embodiment of the present invention is shown, wherein the cable connection unit is provided with a first connection mode and a second connection mode, and the first connection mode and the second connection mode are provided;

In the implementation, the spiral winding connection of the second connection mode is to divide linear conductors such as copper wire conductors into a plurality of groups with the same quantity, each group of copper wires is connected by tightly winding, the winding can be realized by any one of the prior art, and it is understood that when the quantity of the conductors is consistent, the more the number of groups is, the more the contact area of the winding is, and the connection is more stable;
the preset stability is 1/3 of the average impact times received by the area in the history, and it can be understood that in a military scene, the impact force value generated by most situations is very large, such as the impact force caused by a bomb, so that the value of the preset stability is a smaller value, and the stability of the wiring cable is ensured when the workload of part of cable wiring is reduced.
In the military high-voltage cable wiring system, the connecting module is provided with two connecting modes, the two connecting modes are suitable for different cable working environments, when the working environments have a great influence on the stability of the cables, the connecting mode is used for connecting, the stability of the connection is ensured, and when the working environments have a small influence on the stability of the cables, the connecting mode is directly used for contact connection, so that the cable connecting process is simplified.
In particular, the explosion-proof module comprises,
the filling unit is used for insulating and sealing the gap between the connector and the conductor;
the fixing unit is used for fixing the conductors connected by the connector for the first time by using a heat-shrinkable insulating material;
the impact-resistant unit is connected with the fixing unit and is used for secondarily fixing the outer insulating layer at the wiring position after primary fixing, wherein the fixing force of the secondary fixing is determined according to the impact parameters;
wherein the impact parameters include impact direction and impact force.
In the implementation, the gap is insulated and sealed, namely, the gaps at the two ends of the crimping pipe are filled up by using a semi-conductive adhesive tape, so that the gap discharge is avoided, and the used semi-conductive adhesive tape can be any one of the existing semi-conductive adhesive tapes;
the fixing unit uses a thermal shrinkage insulating material to wrap the wiring position of the cable, and then fixes the material in a heating shrinkage mode;
the shock-resistant unit is used for secondarily fixing the wiring positions through the hard materials with the same lengths arranged on the outer insulating layer, the situation that the cable is separated from the connector due to the fact that tension is generated at the wiring positions when the cable shakes is avoided, after the secondary fixing, an explosion-proof shell is arranged outside the hard materials, the wires are wrapped by the hard materials which are secondarily fixed, and the wiring positions are prevented from damaging wiring materials which are secondarily fixed when the wires are impacted greatly.
In the military high-voltage cable wiring system, the explosion-proof module is provided with the filling unit, the filling unit is used for filling the gap between the connector and the conductor, the conductor is fixed after the gap is filled, the fixing stability is improved, meanwhile, gap discharge is prevented, the outer insulating layer is fixed after the conductor is fixed, the stability of cable wiring is further improved in a secondary fixing mode, and the situation that the cable wiring position is separated or loosened after receiving huge impact force caused by bomb explosion and the like is avoided.
Referring to fig. 4, a schematic diagram of determining a fixing force of an explosion-proof module of a military high-voltage cable wiring system according to an embodiment of the present invention is shown, wherein the fixing force is determined according to two forces opposite to each other in a horizontal direction caused by a working scene to a cable wiring position, and the fixing force is determined according to the following formula:
，
wherein F is a fixed force, F1 is the first cable impact force, F2 is the second cable impact force, theta 1 is the angle between the first cable impact force and the first cable horizontal direction, and theta 2 is the angle between the second cable impact force and the second cable horizontal direction.
In the implementation, when the impact is caused to the cable connection position, the stability of the connection part is affected when the horizontal components of the impact forces to the two cables are in opposite directions, so that the included angle between the second cable impact force and the horizontal direction of the first cable is larger than 90 degrees; for exampleF1=1.3×10 7 N，F2=1.7×10 7 N, θ1=27°, θ2=40°, the fixing force f= 2.372 ×10 7 N。
In practice, the source of the impact force is related to the location where the impact occurs, and in particular, for a single device using a military cable, the direction of the source of the impact force that may be received in a single working scene may be set within a sector of no more than 60 °.
It will be appreciated that for a military cable, it is typically located underground, and when it is impacted, the force in the vertical direction at the cable junction is shared by the soil, so for a military cable, the impact force it receives in the horizontal direction is the impact force that the cable junction actually needs to overcome.
Specifically, the position of the butt joint line is detected, wherein the connection strength detection is specifically,
generating corresponding test tension for the cable according to environmental factors in the cable working scene, wherein the test tension comprises a first test tension and a second test tension;
applying the first test tension to a first test point on the carrying cable away from the wiring location, and applying the second test tension to a second test point on the carrying cable away from the wiring location;
and determining the connection tightness degree of the wiring position according to the tensile force generated when the wiring position is deformed and the test tensile force.

the heat conducting material may be any plastic material with insulating function and good heat conducting property, such as heat conducting plastic, heat conducting silicone grease, etc., and is not particularly limited herein.
Specifically, when the accuracy of comparison between the detection result after the wiring adjustment of the cable by the wiring adjustment module and the expected result is higher than the accuracy in the wiring history database, the cloud storage module replaces the data in the original wiring history database.
In the implementation, the wiring adjustment module refers to the content with high similarity in the wiring history database when adjusting the cable, the similarity is determined according to the working environment and the wiring parameters, and under the similar working environment, the closer the wiring parameters are, the higher the similarity is;
under the condition of high similarity, the adjustment quantity should be close to the adjustment quantity value in the history record, if the difference is large, the adjustment is judged to be unreasonable, and the adjustment quantity is determined again.
After the connection process of the cable is adjusted, the connection parameters are re-measured, connection strength detection, current detection and temperature detection are carried out, the detection results are compared with preset values, the closer judgment is that the accuracy is high, and the data in the database are replaced at the moment.
