In the process that the above-mentioned structure detected, the in-process that has probability to take place outside instrument and looped netowrk case mutual contact, the condition that the looped netowrk case took place the electric leakage, the electric leakage current can flow to mobile jib 1 department along locking component 2 this moment, lead to the operating personnel that contacts with mobile jib 1 to take place the electric shock, the insulating effect of handle is not good, and for this reason, mobile jib 1 surface is equipped with insulating cover 12, insulating cover 12 comprises cylindric insulating material's structure, cylindric insulating cover 12's internal diameter is unanimous with mobile jib 1 external diameter, outside mobile jib 1 was located to insulating cover 12 cover, when the electric leakage current was passed to operating personnel along mobile jib 1, insulating cover 12 blockked between mobile jib 1 and operating personnel, the further progress of blocking current has improved insulating effect.
In the process of the insulation function of the structure, since the main rod 1 is used as the holding end, the thickness of the insulation sleeve 12 sleeved outside the main rod 1 is usually thinner, the breakdown voltage is higher than the air with equal thickness, but the insulation effect can not completely meet the requirement when the electric leakage of high voltage is faced, in order to increase the blocking current, the insulation property is further improved, the electric leakage detector 52 is arranged in the locking component 2, the control module 5 is respectively electrically connected with the electric leakage detector 52 and the locking component 2, in the embodiment, the detection end of the electric leakage detector 52 is arranged on one end surface of the lock rod 21 close to the interface, when the electric leakage occurs, the electric current is generated at the lock rod 21, the electric leakage detector 52 detects the voltage of the electric current passing through the lock rod 21 and uploads the voltage to the control module 5, the control module 5 indicates that the electric leakage occurs after the voltage signal is larger than 0 is read, at this time, the control module 5 instructs the locking component 2 to unlock, the lock rod 21 is retracted into the cavity in the lock component 1 after the locking component 2 is unlocked, the connection between the main rod 1 and the interface through the locking component 2 is disconnected, the electric current stops to be transmitted to the main rod 1, and the electric shock is stopped;
in the use process of the main rod 1, the insulating sleeve 12 on the main rod 1 is likely to be damaged after long-term holding or twisting use, and meanwhile, after the locking component 2 is unlocked and disconnected with the connection between the main rod 1 and the connector 4, although a gap exists between the connector 4 and the inner wall of the main rod 1, the condition that the leakage current breaks down the air between the connector 4 and the inner wall of the main rod 1 still can occur, part of current still flows to the main rod 1 after breakdown, when an operator contacts the damaged part of the insulating sleeve 12, the current flows to the operator along the main rod 1 to cause an electric shock accident, however, when the insulating sleeve 12 is not damaged, the breakdown voltage of the insulating sleeve 12 is higher than the same-thickness air breakdown voltage, and therefore, when the control die is controlledIf the determination of the leakage by the block 5 is too strict, the locking module stops fixing the joint 4 under the safety condition, which affects the efficiency of normal operation, and the control module 5 preferably inputs a voltage threshold V in advance for considering the insulation effect and the operation efficiency 0 The voltage threshold is approximately the voltage value of the air between the breakdown joint 4 and the main rod 1, meanwhile, the electric leakage detector 52 uploads the detected voltage V to the control module 5 at a frequency of once per second, and the control module 5 judges whether V is larger than 1/2V after receiving the currently uploaded voltage data V 0 When the judgment result is yes, the leakage current still flows to the main rod 1 after disconnection, although the leakage voltage does not reach a higher degree of breakdown of the insulating sleeve 12, but power failure is still needed to avoid the electric shock risk, at this time, the control module 5 instructs the locking component 2 to unlock, separation between the connector 4 and the main rod 1 is completed before the leakage voltage reaches the breakdown air voltage, and then the main rod 1 and the connector 4 which is lost to lock are separated under the action of external force, or the connector 4 falls back to the main rod 1 after being separated from the contact with the part to be detected of the ring main box under the action of gravity, so that the air thickness between the main rod 1 and the leakage part is further increased, and the situation that the voltage of the leakage part cannot break through air and flows onto the main rod 1 is further ensured;
V 0 can be adjusted according to practical conditions, e.g. V 0 The upper voltage limit which is harmful to human body is set, and at the moment, although the judgment on electric leakage is more strict, the control module 5 can release the locking of the butt joint 4 more frequently, so that the safety can be further improved;
by arranging the leakage detector 52 and enabling the control module 5 to control the locking and unlocking of the locking assembly 2 according to the detection result of the leakage detector 52, the physical separation of the main rod 1 serving as the holding end and the joint 4 serving as the connecting end when the leakage voltage exceeds the threshold value is completed, the transmission path of current from the ring main box to the human body along the operation handle is disconnected, and the insulation effect is improved.
In the above process, after the locking assembly 2 is unlocked and disconnected to connect the main rod 1 and the connector 4, although a gap exists between the connector 4 and the inner wall of the main rod 1, there is still a possibility that the leakage current breaks down the air between the connector 4 and the inner wall of the main rod 1, part of the current still flows to the main rod 1 after breaking down, and the breakdown voltage of the air is related to the thickness of the medium, so that when the size of the connector 4 is larger, the distance between the connector 4 and the main rod 1 is shorter in a short time after unlocking, the thickness of the air between the connector 4 and the main rod 1 is smaller, the breakdown voltage is lower, the air between the connector 4 and the main rod 1 is broken down in the connector 4, the breakdown probability is larger after unlocking is caused by the too high breakdown threshold voltage, and the insulation performance is insufficient, so that the unlocking threshold voltage needs to be reduced when the distance between the connector 4 and the main rod 1 is short, the locking module stops locking the connector 4 under the safe condition when the distance is far, and the normal operation efficiency is influenced, and the distance between the detector 1 and the surface 51 is measured after the distance L between the detector 1 and the connector 1 is further provided;

similarly, when V 0 Set to the upper limit of voltage harmful to human body, the distance L represents the position of the joint 4 after the joint is released from lockingWhen the electric power is in a charged state, the electric power is in contact with the main rod 1, so that the probability of charging the main rod 1 is high, the representative contact probability is high, the electric shock probability is high, the threshold voltage needs to be reduced, when the distance is large, the representative contact probability is small, the electric shock probability is small, and the threshold voltage can be increased;
through setting up the distance detector 51, make control module 5 can judge the air medium thickness between joint 4 and the mobile jib 1 according to distance detection data, simultaneously through the threshold voltage when making control module 5 adjust the unblock judgement according to air medium thickness, accomplish when locking joint 4 of different sizes, control module 5 to the adjustment of unblock threshold voltage, avoided electric leakage breakdown to flow to the unblock under the circumstances of safety when having avoided mobile jib 1, taken into account the operating efficiency.
